The scope of application and reuse of reusable cloth masks

Masks are protective equipment worn on the face to block dust, viruses, and other substances. The outbreak of the new crown epidemic has caused a surge in mask sales. Mask materials such as melt-blown nonwovens and spunbond nonwovens are in short supply. The function of reusable cloth masks is essential to the people's fight against the new crown epidemic.

Scope of application

Chinese masks are mainly divided into three categories: civilian masks, medical masks, and industrial protective masks. Reusable masks, as the name suggests, are civilian masks that can be reused. The group standard "Reusable Masks for Civilians" points out that reusable masks are suitable for blocking microorganisms, droplets, pollen, and other particulate matter in daily life, and their reusable scenarios are mainly for large-scale regional pneumonia, influenza, and other epidemics, as well as other preventive measures. Control the sharp shortage of masks in emergency situations. It must be pointed out that reusable masks, as a kind of civilian masks, cannot be used for medical and industrial dustproof purposes.

Multiplexing

During wear, the mask will block dust and droplets, and absorb pollutants such as atmospheric bacteria, viruses, and particulate matter. . Therefore, when the mask is reused, it is necessary to wash the mask regularly to completely remove the pollutants adsorbed on the mask. In addition, reusable masks should be disinfected regularly to avoid bacterial and viral infections during flu-prone periods or pneumonia outbreaks. Therefore, reusable masks need to be disinfected and cleaned regularly to ensure that the masks themselves are clean and hygienic.

When reusable masks are reused, reasonable and effective decontamination methods are extremely important. The "Reusable Civilian Masks" team standard stipulates that the disinfection and cleaning methods provided by the manufacturer should be combined into one. and cleaning methods, as well as IKEA drying methods that can charge and regenerate the filter layer of the mask, and clearly stipulate the number of decontaminations (not less than 3 times) and the wearing time (not less than 24h). The group standard "Washable and Reusable Fabric Masks" stipulates a stricter number of reuses (50 times) and further clarifies the decontamination methods (washing machine washing, medical alcohol disinfection). According to China's new coronavirus pneumonia diagnosis and treatment plan, masks can be disinfected by medical alcohol disinfection, chlorine-containing disinfectant disinfection, boiling, boiling water, hot water disinfection, steam disinfection, hair dryer hot air disinfection, oven high-temperature disinfection, and ultraviolet disinfection. The research results of the Hong Kong University of Science and Technology of China show that medical alcohol disinfection, steam disinfection, boiling water disinfection, autoclaving disinfection, oven heating disinfection, and ultraviolet disinfection can effectively kill Staphylococcus aureus, and the sterilization rate is as high as 99.99%. Detergent cleaning is only 50.00% efficient in disinfection. Therefore, disinfection is essential during the reuse process of reusable masks during the epidemic. In order to conform to the actual use scenario, the decontamination method should also be suitable for home operation as much as possible. For Chinese consumers, it is easy to clean masks by hand or machine washing followed by drying or air drying, and disinfection is easy to use medical alcohol disinfection or hot or boiling water disinfection.

The process of cleansing the face with a compressed cellulose sponge

Friends who often go to beauty institutions for facial care must know that beauticians will use highly absorbent and soft puffs, which are compressed fibers when cleaning the skin such as makeup removal, dust removal, and facial mask removal for customers. Plain sponge. Although the compressed cellulose sponge sheet looks simple, there are still many skills to use. The following four steps will introduce the process of compressing the cellulose sponge to clean the face.

First: Preparations for cleaning the face

First of all, before the start of the treatment, the beautician needs to prepare a small basin, which contains some warm water to wet the dry sponge (because it can become soft and large after foaming with water), pay attention to this basin must be placed in A place that beauticians have at their fingertips. The temperature of clean water should not be lower or higher, so as not to stimulate customers. When taking out the sponge sheet, it is necessary to squeeze out the excess water inside, so as not to let the water drop on the customer's face and cause discomfort.

Second: the best time to change the water

On the premise of not affecting the cleaning process, the beautician can also use clean water as needed. The most appropriate time is when the customer is steaming the face or applying a hot towel. Another good time to change the water is when the customer is applying When putting on the mask.

Third: the procedure of cleaning the face

1. Take a sponge that has been squeezed through the water in both hands, and alternately clean the neck by rolling upwards, first cleaning one side of the neck, and then cleaning the other side. Repeat several times on each side.

2. Place the sponge on the lower jaw, and clean with both hands along the jaw line to the lower part of the ear at the same time.

3. Roll up the right cheek with both hands to clean from the chin to the temple, and then gradually move to the corner of the mouth.

4. Continue the rolling motion, pass the lower jaw to the left cheek, and repeat the same motion on the left cheek. Clean the area under the nose with both hands from the mid-person to the corners of the mouth at the same time, and repeat several times.

5. Clean the parts under the nose with both hands from the center of the body to the corners of the mouth on both sides at the same time, and repeat several times.

6. Clean the nose and the side of the nose with both hands in an outward motion. Repeat several times.

7. Move both hands alternately upwards from the center of the forehead to the right temple, continue the rolling motion, move to the left temple through the forehead, and then withdraw to the center of the forehead to stop.

8. Gently lift the right eyebrow with the sponge on the left hand, and gently clean the eyelid and eyelashes in a downward motion. Repeat several times or until the eye shadow and eyeliner are all removed. Clean the under-eye area from the outer corner of the eye toward the nose. Repeat the above action on the left eye.

Fourth: force control during cleaning

Whether using a towel or a sponge to clean the skin, the common point is that the force should be gentle, so as not to over-stimulate the skin and make customers feel discomfort or pain.

What is the specific working principle of a handheld 2D scanner

Barcode scanners are also commonly referred to as barcode scanners/readers. They are devices used to read the information contained in barcodes. They can be divided into one-dimensional and two-dimensional barcode scanners.

The structure of barcode scanner is usually the following parts: light source, receiving device, photoelectric conversion component, decoding circuit, computer interface. The basic working principle of the scanning gun is: the light emitted by the light source is irradiated on the barcode symbol through the optical system. The reflected light is imaged on the photoelectric converter through the optical system, and interpreted by the decoder as a digital signal that can be directly accepted by the computer. In addition to one, two-dimensional barcode scanner classification. Also classified as: CCD, full angle laser and laser handheld barcode scanners.

Ordinary barcode scanners usually use the following four technologies: light pen, CCD, laser, and image-type red light.

How the light pen works

The light pen is a handheld barcode scanner that appeared first in the economy. The working principle is to contact the light pen with the barcode, because the barcode label is a line composed of

It is composed of strips that meet black and white, so it can be based on the principle of light reflection: part of the white light is reflected, and part of the black light is absorbed

Receive, compile the barcode by the change of voltage.

How CCD works

The CCD barcode scanner parses the barcode information by covering the entire barcode label with LED light, which is different from the light pen barcode scanner

The only thing is that it scans the entire barcode.

Its advantages are that it is cheap, easy to use, light in weight, and the scanning distance does not need to be in direct contact with the barcode label.

How Laser Works

The laser scanner is the most expensive among many scanners, because it provides more complete functions and better functional indicators, and the current usage is relatively high.

The laser scanner emits a beam of light through a laser diode, and then the light is reflected by the prism and then converted into an electrical signal by the scanner, which finally encodes the barcode. The laser scanner has high recognition and reading ability, can read irregular barcode labels or can identify barcodes by stealing glass and other media, and has good anti-drop performance.

The working principle of image-type red light

The image-type red light barcode scanner has a scanner depth of 30cm and a scanner speed of 300 times per second. It has a particularly good performance in reading barcodes and has a strong decoding ability. It is used for barcodes that cannot be recognized by general barcode scanners The image red light scanner can still be parsed. In addition, the scanner also has rich barcode data editing functions, and the price is not expensive. It is a scanner worth choosing.

Application Prospects of Barcode Scanners

Barcode scanning industry technology has been widely used in many fields and industries, such as retail, manufacturing, logistics, medical, warehousing, and even security. The most used is the QR code scanning technology on WeChat. You can use your phone camera to scan and identify the information contained in the QR code.

The specific principle of Al recognition POS weighting scale

Have you ever had to wait too long at the supermarket and give up buying? Do you encounter slow recognition speed due to employees querying the commodity code table on-site? Have you ever seen businesses increase equipment and personnel in order to reduce queues?

In response to this kind of queuing and weighing problem, we have developed an AI recognition POS weighing scale, which can quickly identify products without entering the product code.

Visual identity technology has its value in all fields, and retail is not uncommon. From automatic checkout, automatic replenishment, and face payment to today's visual recognition scales, this is just the beginning of the application of AI technology in the retail industry. In order to let everyone better understand this trend, today I will reveal the principle of AI recognition POS weighing scales. Help everyone better understand the related issues of AI recognition

AI recognizes the process of POS weighing scale recognition

access to information

It's like seeing things with our eyes. The Al recognition POS weighing scale through the camera to capture the goods on the weighing pan, and converts the light-sensing information into electrical information that the machine can recognize. For example, in image description, a photo can be described by describing the hue, saturation, brightness and other parameters of each pixel through the HSB color mode. In addition, there are many common methods such as RGB, LAB, and grayscale.

preprocessing of information

The process of processing photos before image recognition, including the selection and processing of information. The first is selection. When the camera takes a photo, we need to quickly select the clearest one to use among the multiple photos taken. Next is the photo noise reduction process. Here is the processing of images. Including image restoration and filling, image dehazing, image contrast enhancement, image lossless enlargement, stretch image restoration, image sharpness enhancement, image color enhancement, etc. In the end, just to eliminate interference factors, get a photo that is most suitable for the algorithm to identify.

Feature extraction and selection

A simple understanding is that the images we study are of various kinds. Some images contain apples, and some images contain bananas. If we want to classify these images, we must identify them by their own characteristics. The process of obtaining features such as bananas and apples is feature extraction. The features obtained in the feature extraction may not be useful for this identification. For example, there is a label on the apple, and we have no plan to identify it through the label. At this time, we must extract the features related to the apple and discard the label Features, this is the selection of features. Feature extraction and selection is one of the key technologies in the image recognition process, so understanding this step is the focus of image recognition.

Classifier Design and Classification Decisions

Classifier design refers to obtaining a recognition rule through training, through which a feature classification can be obtained, so that the image recognition technology can obtain a high recognition rate. Classification decision refers to classifying the identified objects in the feature space, so as to better identify which category the object under study belongs to. For example, in the identification of uncoded products, we found that the features with large areas of leaves belong to vegetables, because we can add the category of vegetables to the feature classification, so that when the algorithm finds the features of large areas of leaves, it will be in the Match in the category of leafy vegetables, instead of going to the category of fruits or dry goods.

The difference between thermal printers and ordinary printers

With the rapid development of communication technology and logistics, printers have been popularized in various places. In daily life, the printers in the hands of couriers are generally thermal printers, while most of the printers in the office are inkjet printers. Today I will explain to you the difference between thermal printers and other printers.

The difference

1. The subject is different. Thermal printers are printers that print using thermal methods. Ordinary printers use dot-type, ink-jet, or laser methods to print.

2. The principle is different. The thermal printer is equipped with a semiconductor heating element on the print head, and the print head can print the desired pattern after heating and contacting the thermal printing paper. Ordinary printers first generate small ink droplets and then use the inkjet head to guide the small ink droplets to the set position. The smaller the ink droplet, the clearer the printed picture.

Working principle

The working principle of a thermal printer is that a semiconductor heating element is installed on the print head. After the print head is heated and contacts the thermal printing paper, the desired pattern can be printed. The image is heated to generate a chemical reaction in the film. This thermal printer chemical reaction needs to be carried out at a certain temperature, and a high temperature will accelerate this chemical reaction. When the temperature is below 60 degrees Celsius, it takes a considerable amount of time for the paper to turn dark; when the temperature is 200 degrees Celsius, the reaction is completed in a few microseconds.

Thermal printing technology was first used in fax machines, and thermal printers have been widely used in POS terminal systems, banking systems, medical instruments and other fields. Thermal printers can only use special thermal paper. The thermal paper is coated with a coating that will change color due to a chemical reaction when heated, similar to the photosensitive film, but this coating will change color when heated. This characteristic of thermal coatings has led to the emergence of thermal printing technology.

Advantages of thermal printers

1. High printing speed and low noise

2. The large gear is durable

3. Support QR code printing

4. Multiple international languages are available

5. Easy paper loading

6. Optional communication interface (such as USB+, parallel port, USB+Ethernet)

At present, thermal printers are equipped with cutters. With the existence of cutters, the work efficiency of the printer is greatly improved. After printing one sheet, one sheet can be cut, saving a lot of unnecessary wasted time. There are many types of printers, various brands, and various configurations, but often some customers cannot make full use of these products because they do not understand these products. Before buying a thermal printer, be sure to understand its related parameters and the label content you need to print. According to these two points, you can buy a printer that suits you.

Reasons why supermarkets use touch screen billing pos machines

With the development of the economy, the traditional cash register methods such as manual checkout have been abandoned by the times due to their low efficiency and high error rate, and the use of smart cash registers has become the most important cash register method.

Nowadays, almost every store is using touch screen billing machines, ranging from supermarkets to small convenience stores. Now smart touch screen billing machines generally use the Android system. Why are single-screen smart touch-screen billing machines and dual-screen smart touch-screen billing machines the first choice for many businesses? We can think that compared with the traditional cash register screen like the previous computer monitor, the Android version of the touch screen billing machine can not only realize various cash register payments but also have functions such as a built-in receipt printer, commodity scanning window, etc., which greatly improves the efficiency of convenience.

Advantages of touch screen billing machines in supermarkets

The touch screen billing machine is the necessary auxiliary equipment for modern commercial enterprises. The intelligent touch cash register is mainly used in department stores, supermarkets, chain stores, hotels, restaurants, bookstores, gas stations, canteens, and other industries. The following is an analysis of the advantages of the smart touch screen billing machine:

1. The touch screen billing machine adopts the current popular capacitive screen touch control technology, which can enhance the enthusiasm of employees and improve their enthusiasm for work. At the same time, the operation time of employees is reduced and the efficiency is improved.

Types of medical protective clothing, use occasions and design ideas

Since the beginning of the 21st century, outbreaks of infectious diseases have continuously challenged human society, and high-level diseases such as SARS, H5N1 avian influenza, H5N1 influenza, Ebola, and new coronary pneumonia (COVID-19) have appeared one after another. Infectious diseases. In order to ensure that medical personnel who are fighting on the front line of the epidemic are not infected by the virus, the demand for high-safety personal protective clothing is increasing, which has also promoted the in-depth research and rapid development of related technologies and equipment. In addition, because biological laboratory researchers may come into direct contact with high-risk and high-concentration viruses, the protective performance requirements of the positive pressure biological protective clothing they are equipped with are undoubtedly higher. Therefore, the research and development of biological protective clothing are also of great significance.

Types and application of non-woven protective materials

The scope of application of GB 19082-2009 "Technical Requirements for Medical Disposable Protective Clothing" stipulates that medical personnel must wear for isolation and protection when working in contact with potentially infectious patients' blood, body fluids, secretions, and particulate matter in the air. medical disposable protective clothing. At present, most of the medical protective clothing used in domestic and foreign hospitals is a disposable composite material with non-woven fabric as the main fabric, which is not only hygienic and convenient but also effectively prevents iatrogenic cross-infection. The preparation technologies of non-woven medical protective materials generally include spunbond, meltblown, spunbond-meltblown-spunbond (SMS) composite, spun lace, and flash evaporation; composite processing technologies include finishing, coating and lamination, etc. craft. As far as the nonwoven material itself is concerned, the common polypropylene spunbond nonwoven fabric and the spun lace fabric composited with polyester fiber and wood pulp are soft, comfortable, and inexpensive, but have poor protective performance and can only be used for sterile surgical operations. General protective equipment such as clothing, sterilization wraps, etc. Meltblown nonwovens have small fiber diameters and high porosity, and their barrier properties are better than spunbond nonwovens and spunlaced nonwovens, but their strength and wear resistance are poor, and they are only suitable for occasions that do not require high strength. Polypropylene SMS composite non-woven material combines the advantages of spun-bond non-woven fabric and melt-blown non-woven fabric and is suitable for certain invasive occasions. It has been widely used at home and abroad as a high-end surgical gown. Not suitable for highly infectious areas with special post-treatment. The overall performance of the flash-evaporation protective clothing developed by DuPont in the United States is very good, which can protect the wearer from particles as small as microns, and plays a crucial role in the barrier of viruses and microorganisms, but its domestic application is limited Manufacturing technology and cost constraints. For composite materials with non-woven fabrics as the main body, the materials made by composite processing technology can be used in areas with strong infectious power, but the breathability and moisture permeability of various materials are not the same, to a large extent. Will affect the wearing comfort of medical staff. Although traditional coating materials and polyurethane non-porous film composite materials have good protective effects, they have poor thermal and humid comfort, which is not conducive to the efficient work of medical staff. The "three-rejection and one-antibody" (alcohol-repellent, blood-repellent, oil-repellent and antistatic) SMS composite materials are based on functional finishing and lamination process respectively, and a layer of breathable composite material on the original non-woven fabric substrate The coating material of the microporous film has both protection and wearing comfort to a certain extent, and together with the flash evaporation method mentioned above, it has become the mainstream medical protective clothing material used in major epidemic prevention and control occasions.

Design ideas for medical protective clothing

The design requirements of medical protective clothing include meeting protection, comfort, and physical and mechanical properties. Protection is isolation performance, including liquid barrier and anti-permeability, particle barrier and anti-microbial permeability, etc.; comfort includes breathability and moisture permeability, antistatic and operational flexibility; physical and mechanical properties include breaking strength, seam strength, piercing strength and fluffing, etc. Protection and breathability are often opposed, so comfort should be satisfied on the basis of protection, and a relative balance between the two should be found. It is worth noting that although the diameter of the virus is nanoscale (for example, the diameter of the SARA coronavirus is 80-120 nm, and the diameter of the new coronavirus is 60-140 nm), it cannot exist independently, and is generally found in body fluids, blood, and droplets. Liquids, aerosols, and suspended microparticles are used as carriers to indirectly contact the human body. Therefore, only on the premise of clarifying the overall performance requirements of virus transmission carriers and medical protective clothing, can further select appropriate protective clothing fabrics, and make sure that the clothing is not affected. Design and forming put forward corresponding requirements.

Standards for medical protective masks in different countries

Masks are an essential item in the fight against the epidemic. There are many types of masks on the market. Wearing a suitable mask is an important guarantee for scientific epidemic prevention. Below, we will introduce the relevant standards for masks in various countries.

1. Medical protective masks

1) China's implementation standard: GB 19083 standard, which is currently the most demanding protective mask in the domestic medical field. The technical indicators are detailed in GB 19083, which can be used for the protection of high-risk and high-exposure front-line medical staff and staff.

Function: Anti-foaming, good air tightness, flame retardant, anti-liquid splash. Generally used for professional medical staff.

2) American standard: N series masks (N means that it is not suitable for oily particles (for example, the oily particles produced by cooking are oily particles, and the droplets produced by people talking or coughing are not oily))

Executive standard: GB 19083-2010*. The formulation of GB 19083-2010 originated from SARS in 2003. At that time, it was found that N95 masks can effectively prevent the spread of viruses. Therefore, the 2003 version requires particle filtration efficiency ≥95%. Subsequently, the standard was revised to add anti-synthetic blood penetration, anti-water resistance, etc. performance.

Function: It is suitable for medical work environments with strong pathogenic transmission and a great need for protection. It is characterized by barrier protection and strong adhesion. It is mainly used for medical care and staff on the front line of the epidemic. It is not recommended for the elderly, children, and frail healthy adults to wear it.

2. Other alternative medical protective masks

Function: It can be used as a substitute for medical protective masks in non-medical institutions, and the effect is inferior to that of medical protective masks.

1) Chinese standard: KN series masks (KN itself refers to non-oily particles)

Executive standard: GB2626-2006. GB 2626-2006 is a mask used in the field of safety supervision and labor insurance to protect workplaces from the inhalation of various particulates. The test methods and requirements of KN95 and N95 in the US Federal Regulations 42 CFR Part 84 are similar, so they can play a better role. Barrier protection, its 2019 version will be implemented in the second half of 2020.

Mask level: KN90, KN95, KN100, KP90, KP95, KP100. (KN type is only suitable for filtering non-oily particles, KP type is suitable for filtering non-oily particles and oily particles, so KP type has a stronger protective effect.)

2) Korean standard: KF series masks

Implementation standard: Korea Food and Drug Administration (MFDS) standard (no standard number)

Mask level: KF80, KF94, KF99. (Example: KF94 mask means that the filtration rate of particles with a diameter of 0.4 μm is greater than 94%)

3) European standard: FFP series masks

Executive standard: CE certification level of respirator according to EN149 standard (EN 149:2001+A1:2009 FFP2)

Mask level: FFP1, FFP2, FFP3. (The object protection filter material is divided into two specifications for solid particle protection and liquid particle protection. The minimum filtration effect of FFP1 is ≥80%, the minimum filtration effect of FFP2 is ≥94%, and the minimum filtration effect of FFP3 is ≥97%.)

4) Japanese standard: DS series masks

Executive standard: JS-T-8151 standard

5) Australian standard: P series masks

Executive standard: AS 1716 standard (AS/NZS 1716:2012)

6) Specifications of other standard protective masks

The current common classification is based on the three indicators of the Nielsen laboratory: VFE (viral filtration efficiency), BFE (bacterial filtration efficiency), and PFE (particulate filtration efficiency). Among them, BFE simply refers to the filtration efficiency of 3 μm particles, while PFE usually has the filtration efficiency of 0.3 μm. BFE greater than 95% can be used as a secondary substitute, but it should be noted whether it meets the national standard.

3. Medical surgical masks

Executive standard: YY0469-2011*.

Function: Relatively cheap, anti-foaming, flame retardant, anti-liquid splash, but poor air tightness. It is suitable for medical staff to prevent infection during surgery. The main function is to protect medical staff. The key indicators are anti-synthetic blood penetration, bacterial filtration efficiency, and particulate filtration efficiency. Spread, protect yourself and those around you.

Description: The biggest feature is the design of flame retardant and liquid splash resistance, which also makes them more suitable for use in medical environments.

4. Disposable medical masks

Executive standard: YY/T 0969-2013

Function: cheap, anti-splash of self-pollutants, but poor air tightness. It is suitable for wearing in ordinary medical environments and is the most common mask that can be seen in daily pharmacies. It is also suitable for people to wear protection during the epidemic.

What is the difference between silicone sponge and rubber sponge

Rubber is divided into natural rubber and synthetic rubber. The structure of natural rubber is a high polymer of isoprene, and synthetic rubber such as butadiene rubber, neoprene, styrene-butadiene rubber, etc. As a kind of rubber, silica gel has the characteristics of high and low temperature resistance, weather resistance, ozone resistance, non-toxicity and environmental protection. Silicone and rubber cannot be said which is better, it can only be said that it is good to apply it in the right way. The following is a detailed introduction to the difference between silicone and rubber.

The difference

Rubber is divided into natural rubber and synthetic rubber. The structure of natural rubber is a high polymer of isoprene, and synthetic rubber such as butadiene rubber, neoprene, styrene-butadiene rubber, etc. When the cross-linked rubber is deformed by external force, it can recover quickly, and has good physical and mechanical properties and chemical stability.

Silicone rubber is mainly composed of high molar mass linear polysiloxane. Since the Si-O-Si bond is the basic bond type, the silicon atom is mainly connected to the methyl group, and a very small number of unsaturated groups is introduced into the side chain. It is arranged outside and can rotate freely, so after vulcanization, silicone rubber has excellent high and low temperature resistance (-100~315℃), weather resistance, water repellency, electrical insulation, physiological inertia and other characteristics. It has been widely used in production and people's daily life. The most important thing is that it is not toxic, and it is commonly used in pacifiers and breast augmentation fillers.

1. The two definitions are different. Rubber is a general term that includes many types, such as natural rubber, cis-butadiene rubber, styrene-butadiene rubber, propylene rubber, and of course silicone rubber; and silicone is one of the specific varieties of rubber.

2. Rubber has a wide range of uses, mainly using the elastic effect of rubber, such as rubber tires, bridge shock absorption, hose rubber rollers, etc., mainly in industrial applications; silicone is mostly used in food and household appliances, such as Pacifiers, spoons for children, pressure cooker seals, etc.

3. Different types and grades of rubber have different applications. For example, natural rubber is mainly used for tires, butyl rubber is mainly used for inner tubes, and EPDM rubber is used for sealing products.

4. When choosing rubber, it needs to be based on specific performance requirements, such as hardness, tensile strength, compression deformation, wear, tear, use environment, etc. From their properties, we can see that silicone rubber has the incomparable advantages of ordinary rubber. The price of silicone rubber is more expensive. Which one is better depends on our use? If ordinary rubber products can meet our needs, there is no need to kill chickens with a knife, use better performance and higher price silicone.

Sponge silicone tube is a kind of special rubber with a wide range of comprehensive properties. It has excellent electrical insulation properties, aging resistance, chemical stability, oxidation resistance and weather resistance, radiation resistance, physiological inertia, good air permeability, high and low temperature resistance, and can be Long-term use at -60℃～250℃.

What precautions should be taken before and after colonoscopy?

Colonoscopy, also known as an electronic colonoscopy, is a diagnostic method that doctors use to examine the interior of the large intestine and terminal ileum. A colonoscope is a slender, flexible instrument, about 1 cm in diameter, that is passed through the anus into the large intestine. The front end of the electronic colonoscope is equipped with a camera, and the image is transmitted to the display through the optical fiber, allowing the doctor to see the picture inside the intestine in real-time; it can also transmit the signal to the acquisition system to take a picture of the inside of the intestine. Usually, there is also a channel for placing operating instruments inside the colonoscopy, so that the tissue can be clamped under the colonoscope for pathological examination, and even operations such as resection of lesions can be performed.

In what situations do you need a colonoscopy?

1. Unexplained blood in the stool.

2. Changes in defecation habits: increased stool frequency or frequent bowel movements, but no stool discharge, or constipation.

3. Chronic diarrhea of unknown cause.

4. Mucus or pus and blood-like fluid in the stool.

5. Stool thinning. Flattened.

6. Abdominal mass, cannot rule out the large intestine and terminal ileum lesions.

7. Middle and lower abdominal pain of unknown cause.

8. Suspected benign or malignant colon tumor, which cannot be diagnosed by X-ray examination.

9. Suspected chronic intestinal inflammatory disease.

10. If an abnormality is found in barium enema or bowel system examination, it is necessary to further clarify the nature and scope of the lesions.

11. Determining the lesion range before the colon cancer surgery, re-examination, and curative effect follow-up after colon cancer polyps.

12. Abdominal distension. Abdominal pain and other unexplained low intestinal obstruction.

How to prepare for a colonoscopy?

The day before colonoscopy:

1. Only eat a slag-free semi-liquid diet, and do not eat vegetables and fruits containing fiber.

2. Take a laxative (such as 2 bisacodyl enteric-coated tablets) before going to bed at night.

Colonoscopy day:

1. Fasting before colonoscopy.

2.8:00 Start taking intestinal cleansers (such as polyethylene glycol electrolyte powder, see the video for how to take it). It is recommended not to go out at this time, so as not to find the toilet.

3. If necessary, take an antifoam (such as Simethicone Emulsion 30ml) one hour after taking the bowel cleanser. So, all the medicines have been taken.

4. Excretion will start about an hour after taking the medicine. When the excrement turns yellow or colorless water-like stool, the intestinal preparation is basically over.

What should I pay attention to after the inspection?

1. It is recommended that patients come to the hospital to be accompanied by their family members.

2. Stop taking iron grades (such as ferrous sulfate, polysaccharide iron, etc.) three days before the examination.

3. Long-term constipation patients should explain to the doctor in advance.

4. No food was eaten on the day of the colonoscopy, and hypoglycemic drugs before meals do not need to be taken.

5. Antihypertensive drugs should be taken one hour before bowel cleansing.

6. On the day of the colonoscopy, if there is dizziness and hypoglycemia without eating, you can take sugar water to replenish energy.

7. Be sure to inform your doctor about the long-term use of anticoagulants (such as aspirin, warfarin, clopidogrel, etc.).

8. If severe abdominal pain, abdominal distension, blood in the stool, etc. occurs 1-2 days after the examination, seek medical attention immediately.

9. Do not drive, ride, or work at heights within 8 hours after colonoscopy.
