Maintenance of biological safety cabinet

In order to ensure the safety of the biological safety cabinet, the safety cabinet should be maintained and maintained regularly:

1. The working area of the safety cabinet should be cleaned and disinfected before and after each use. 2. After the service life of the HEPA filter expires, it should be replaced by a professional who has received special training in biological safety cabinets. 3. The laboratory biosafety manual promulgated by WHO, the U.S. biosafety cabinet standard NSF49 and the China Food and Drug Administration biosafety cabinet standard YY0569 all require one of the following conditions, the biosafety cabinet should be tested for safety: the installation is completed and put into use Before; annual routine inspection; when the safety cabinet is shifted; after replacing the HEPA filter and repairing internal parts. Safety inspection includes the following aspects: 1. Inlet flow direction and wind speed detection: Inlet flow direction is detected on the working section by smoke method or silk thread method. The detection position includes the periphery and middle area of the working window; the wind speed of the intake flow is measured by the anemometer at the section wind speed of the working window. 2. Detecting the wind speed and uniformity of the sinking airflow: use an anemometer to measure the wind speed of the cross-section evenly. 3. Cleanliness detection of working area: adopt dust particle timer to detect in the working area. 4. Noise detection: the horizontal center of the front panel of the biological safety cabinet is 300mm outwards, and the noise is measured with the sound level at a position 380mm higher than the work surface. 5. Illumination detection: set a measuring point every 30cm along the center line of the length of the worktable. 6. Leakage detection of the cabinet: Seal the safety cabinet and pressurize it to 500Pa. After 30 minutes, connect a pressure gauge or pressure sensor system to the test area for detection by the pressure decay method, or by the soap bubble method.

Classification and selection principles of biological safety cabinets

According to the NSF49 standard, the medium of biosafety level 1 (P1) refers to ordinary harmless bacteria, viruses and other microorganisms; the medium of biosafety level 2 (P2) refers to general pathogenic bacteria, viruses and other microorganisms; biosafety The medium of level 3 (P3) refers to microorganisms such as potent/fatal bacteria and viruses, but can be cured after infection; the medium of biosafety level 4 (P4) refers to microorganisms such as potent/fatal bacteria, viruses, etc., which are not easily cured after infection .

This standard divides biological safety cabinets into gradesⅠ,Ⅱ, andⅢ, which can be applied to the operation of media of different biological safety grades.

Principles for selecting biological safety cabinets in biosafety laboratories

Generally, there is no need to use a biological safety cabinet when the laboratory level is level 1, or use a level I biological safety cabinet. When the laboratory level is level two, when microbial aerosols or splashing operations may occur, a level I biological safety cabinet can be used; when handling infectious materials, a level II biological safety cabinet with partial or full exhaust should be used ; If it involves handling chemical carcinogens, radioactive substances and volatile solvents, only Class II-B full exhaust (B2 type) biological safety cabinets can be used. When the laboratory level is level three, a level II or level III biological safety cabinet should be used; all operations involving infectious materials should use a fully exhausted type II-B level (B2 type) or level III biological safety cabinet. When the laboratory level is level four, a level III full exhaust biological safety cabinet should be used. When personnel wear positive pressure protective clothing, a Class II-B biological safety cabinet can be used.

[healforceworld]

The structure of the biological safety cabinet

Biological safety cabinets generally consist of two parts: a box body and a bracket. The body part of the biological safety cabinet mainly includes the following structures:

1. Air Filtration System

The air filtration system is the most important system to ensure the performance of this equipment. It consists of a driving fan, an air duct, a circulating air filter and an external exhaust air filter. Its main function is to continuously bring clean air into the working room, so that the flow rate of the sinking airflow (vertical airflow) in the working area is not less than 0.3m/s, and ensuring that the cleanliness in the working area reaches Class 100. At the same time, the external exhaust flow is also purified to prevent environmental pollution.

The core component of the system is a HEPA filter, which uses a special fire-resistant material as the frame. The frame is divided into grids with corrugated aluminum sheets, filled with emulsified glass fiber sub-fine particles, and its filtration efficiency can reach 99.99% to 100%. The pre-filter cover or pre-filter at the air inlet makes the air pre-filtered and purified before entering the HEPA filter, which can prolong the service life of the HEPA filter.

2. External exhaust air box system

The external exhaust air box system is composed of an external exhaust air box shell, a fan and an exhaust duct. The external exhaust fan provides exhaust power to extract the unclean air in the working room, and it is purified by the external exhaust filter to protect the samples and the experimental items in the cabinet. Due to the external exhaust function, the working room is under negative pressure to prevent The air in the work area escapes to protect the operator.

3. Sliding front window drive system

The sliding front window drive system is composed of the front glass door, door motor, traction mechanism, drive shaft and limit switch, etc. The main function is to drive or traction each door shaft so that the front glass door is in the normal position during the operation of the equipment.

4. The illuminating light source and ultraviolet light source are located inside the glass door to ensure a certain brightness in the working room and to disinfect the work surface and air in the working room.

5. On the control panel, there are devices such as power supply, ultraviolet lamp, lighting lamp, fan switch, and control the movement of the front glass door. The main function is to set and display the system status.

What is a biological safety cabinet?

Biological safety cabinet (BSC) is a box-type air purification negative pressure safety device that can prevent certain dangerous or unknown biological particles from aerosols from escaping during the process of experimental operation. It is widely used in scientific research, teaching, clinical testing and production in the fields of microbiology, biomedicine, genetic engineering, biological products, etc. It is the most basic safety protection equipment in the first-level protective barrier of laboratory biosafety.

Working principle of biological safety cabinet

The working principle of the biological safety cabinet is mainly to suck the air inside the cabinet to maintain a negative pressure in the cabinet, and protect the staff through the vertical airflow; the outside air is filtered by a high-efficiency particulate air filter (HEPA) After filtering, enter the safety cabinet to avoid contamination of the processed samples; the air in the cabinet also needs to be filtered by a HEPA filter before being discharged into the atmosphere to protect the environment.

Advantages of real-time fluorescence quantitative PCR instrument

Real-time fluorescence quantitative PCR instrument, composed of fluorescence quantitative system and computer, is used to monitor the fluorescence in the cycle process. A computer connected to a real-time device collects fluorescence data. The data is displayed in the form of graphs through the developed real-time analysis software. The raw data is plotted as a graph of fluorescence intensity versus cycle number. After the raw data is collected, the analysis can be started. The software of the real-time device can normalize the collected data to compensate for the difference in background fluorescence. After normalization, the threshold level can be set, which is the level of analysis of fluorescence data.

The number of cycles the sample goes through to reach the threshold level is called the Ct value (the number of cycles at the limit point). The threshold should be set to maximize the amplification efficiency in the exponential phase, so that the most accurate and repeatable data can be obtained. If a standard product with the corresponding concentration is also amplified at the same time, the linear regression analysis will generate a standard curve, which can be used to calculate the concentration of the unknown sample.

[healforceworld]

Real-time PCR and reverse transcription PCR

Real-time PCR and reverse transcription PCR, the abbreviations of the two are RT-PCR, are there any similarities and differences between these two concepts?

Real-time PCR is a type of quantitative PCR (Q-PCR), which performs quantitative analysis of DNA based on the increase in DNA within a certain period of time.

Fluorescent pigments are used for quantification in real time PCR, and there are currently two methods. One is to insert a specific fluorescent pigment into the ds DNA; the other uses a fluorescent probe that can be combined with a specific oligonucleotide sequence in the amplified DNA sequence.

Reverse transcription PCR, or reverse transcription-PCR (RT-PCR), is a widely used variant of polymerase chain reaction (PCR). In RT-PCR, an RNA strand is reverse transcribed into complementary DNA, which is then used as a template for DNA amplification by PCR.

The transcription of a single strand of RNA into complementary DNA (cDNA) is called "reverse transcription", and it is done by RNA-dependent DNA polymerase (reverse transcriptase). Subsequently, the other strand of DNA is completed by deoxynucleotide primers and DNA-dependent DNA polymerase, which doubles with each cycle, that is, the usual PCR. The original RNA template is degraded by RNase H, leaving behind complementary DNA.

The exponential amplification of RT-PCR is a very sensitive technique that can detect very low copy number RNA. RT-PCR is widely used in the diagnosis of genetic diseases, and can be used to quantitatively monitor the content of a certain RNA. (For methods of detecting gene expression, see Northern Blot method.)

RT-PCR is sometimes referred to as real-time PCR. In order to distinguish it from reverse transcription PCR, it is usually written as quantitative PCR or RTQ-PCR (real-time quantitative PCR).

The combination of real time PCR and reverse transcription PCR can use a small amount of RNA to find the specifically expressed genetic genes in a specific time, cell, and tissue. The combination of these two types of RT-PCR is also called "quantitative RT-PCR"

[healforceworld]

Real-time fluorescence quantitative PCR

The so-called real-time fluorescent quantitative PCR technology refers to the method of adding fluorescent groups to the PCR reaction system, using the accumulation of fluorescent signals to monitor the entire PCR process in real time, and finally quantitatively analyzing the unknown template through the standard curve.

Detection method

1. SYBRGreenⅠ method:

In the PCR reaction system, an excess of SYBR fluorescent dye is added. After the SYBR fluorescent dye is specifically incorporated into the DNA double-strand, it emits a fluorescent signal. The SYBR dye molecule that is not incorporated into the chain will not emit any fluorescent signal, thereby ensuring the fluorescent signal The increase in PCR products is completely synchronized with the increase in PCR products.

SYBR quantitative PCR amplification fluorescence curve

Melting curve graph of PCR product (single peak graph indicates the unity of PCR amplified product)

2. TaqMan probe method:

When the probe is intact, the fluorescent signal emitted by the reporter group is absorbed by the quenching group; during PCR amplification, the 5'-3' exonuclease activity of Taq enzyme cleaves and degrades the probe, making the reporter fluorescent group and quencher The fluorescent group is separated, so that the fluorescence monitoring system can receive the fluorescence signal, that is, every time a DNA strand is amplified, a fluorescent molecule is formed, and the accumulation of the fluorescence signal is completely synchronized with the formation of the PCR product.

[healforceworld]

Real-time PCR technology use

Real-time PCR technology can be used not only for basic research such as gene isolation, cloning and nucleic acid sequence analysis, but also for disease diagnosis or any place where DNA and RNA are present.

Polymerase chain reaction (English full name: Polymerase Chain Reaction), polymerase chain reaction, referred to as PCR. Polymerase chain reaction (PCR) is a method of enzymatically synthesizing specific DNA fragments in vitro. It consists of several steps of high temperature denaturation, low temperature annealing (renaturation) and temperature extension. Rapid expansion.

[healforceworld]

Real-time PCR quantitative definition

Real-time quantitative polymerase chain reaction (Real-time quantitative polymerase chain reaction, referred to as Real Time PCR) is a nucleic acid quantitative technology developed on the basis of qualitative PCR technology.

The real-time fluorescent PCR quantitative technology was launched by Applied Biosystems in 1996. Fluorophores were added to the PCR reaction system and the fluorescence signal accumulation was used to monitor the entire PCR process in real time, so that each cycle became "visible", and finally passed the Ct value and The standard curve is a method for quantifying the initial concentration of DNA (orcDNA) in a sample.

Real-time fluorescent PCR quantification is currently the most sensitive and accurate method for determining the copy number of DNA (or cDNA) in a sample. If used for RNA detection, this is called reverse transcription real-time PCR (Real-time RT-PCR) is a real-time PCR method, which refers to the DNA or reversed-in (RT-PCR) RNA through the polymerase chain React and monitor the DNA amplification process in real time, and measure the amplified product during the exponential growth phase of the amplification, because the measured value of the exponential growth phase of the amplification is correlated with the initial amount of specific DNA (RNA), thereby realizing quantitative detection. The basic goal of RealTime PCR is to accurately measure and identify very small amounts of specific nucleic acids, so that the content of the original target gene can be quantified by monitoring the CT value. The biggest advantage of the real-time fluorescent quantitative PCR method is to overcome the large error of the end-point PCR method after entering the plateau or saturation period, and realize the accurate quantification of DNA/RNA. This technology not only realizes the quantification of DNA/RNA templates, but also has the characteristics of high sensitivity and specificity, multiple reactions, high degree of automation, pollution-free, real-time and accuracy, etc. The technology is used in medical clinical testing and clinical medical research. It has important meaning.

How important is heart health? ECG machines focus on your concerns!

Our heart is one of the important vital organs of our body. With the irregular lifestyle of modern workers and the increasing work pressure, the burden on the heart is gradually increasing. Nowadays, cardiovascular health has become an important topic of general concern in the global medical community. People’s physical functions often decline when aging, and cardiovascular disease has become a major health concern for middle age person or even younger range.

In 2019, the British Medical Journal published research on cardiovascular disease, found out that having a good cardiovascular status at the age of 50 or older can reduce the risk of dementia.

With the advancement of medical technology, home-used electrocardiogram devices have become more and more popular in people’s homes, helping people to manage their heart health more conveniently, but for some users, it is hard to even start buying an ECG when there are different types of ECGs in the market. It can be quite overwhelming and complicated. Let’s learn about the relevant knowledge of the ECG devices. Hopefully after reading this article, it is clear to you when selecting an ECG.

What are the types of ECGs(electrocardiogram)?

The ECG devices can be divided into single-lead and multi-lead (such as three-lead, six-lead, twelve-lead) electrocardiograph according to the signal derivative that can be recorded at one time.

Single-lead ECG

The single-lead ECG machine has one ECG signal amplification channel, that is, one waveform is displayed on the screen at a time. It is a household ECG testing instrument often used at home. It has the advantages of convenient and easy operation, simple and fast. Heal Force PC-80B Easy ECG, provides quick measurement in 30 seconds, can store 2700 sets or 22.5 hours of ECG monitoring waveforms, it is an essential device to monitor your heart anytime, anywhere.

Multi-lead ECG

The multi-lead ECG machine has multiple amplification channels, which can simultaneously reflect the changes in the ECG signal of multiple leads. The ECG signal changes measured by the multi-lead ECG machine are more comprehensive, which is helpful to judge the heart condition. Heal Force 3-lead ECG PC-80D display three waveforms on 3.5inch LCD screen. It is able to detect up to 19 types of arrhythmia results, provide accurate measurement and real-time feedback.

Heal Force 3-lead ECG PC-80D

Lead wires are needed for long-term ECG monitoring. The more leads, the more ECG measurements, therefore the more heart states observed. For example, myocardial ischemia is often clinically asymptomatic, and the 12-lead ECG system can be used to reflect symptoms in time. Almost 70% to 90% of myocardial ischemia is discovered through 12-lead monitoring. Therefore, the multi-lead professional electrocardiogram is very important to diagnose the nature of diseases such as arrhythmia, determine the treatment method, and observe the treatment effect.

Heal Force 12-lead ECG

Keep away from Indigenous Method and Be Wary of Neonatal Jaundice

What You Need to be Careful about Yellowing of Babies’ Skin

Due to the abnormal metabolism of bilirubin, the blood bilirubin level is increased, and symptoms characterized by yellow staining of the skin, mucous membrane, and sclera appear, which is a common clinical problem in newborns.

Therefore, when parents see a new-born baby, if they have symptoms such as sudden yellowing of the skin, they must not take it lightly. Many elderly people will give a variety of solutions, such as “feeding water constantly, taking a bite of honey”, etc., which are the “indigenous method” often heard by novices and parents. We kindly remind you that newborn babies have delicate skin and incomplete digestive and respiratory system development. When they encounter neonatal jaundice, parents should ask their doctors for professional diagnosis, determine the baby's health, and follow the doctor's instructions for follow-up diagnosis and treatment.

Causes of Jaundice

Generally speaking, the occurrence of neonatal jaundice is divided into physiological jaundice and pathological jaundice.

(1) Physiological jaundice Physiological jaundice is related to the characteristics of neonatal bilirubin metabolism, including relatively high bilirubin production, insufficient uptake of bilirubin by hepatocytes, poor ability of plasma albumin to connect to bilirubin, and defective bilirubin excretion capacity, increased enterohepatic circulation and other reasons. Therefore, 60% of full-term infants and 80% of preterm infants may have visible jaundice in the first week after birth.

(2) Pathological jaundice

Excessive bilirubin production Due to the destruction of excessive red blood cells and the increase of enterohepatic circulation, the unbound bilirubin in serum increases.

Hepatic bilirubin metabolism disorder Due to the low uptake and binding of bilirubin by hepatocytes, the unconjugated bilirubin in serum increases.

Bile excretion disorders Hepatocyte excretion combined with bilirubin disorder or bile duct obstruction can cause hyperconjugated bilirubinemia, but if it is accompanied by impaired liver cell function, there may also be an increase in unconjugated bilirubin.

How to Deal with Neonatal Jaundice?

Light therapy is a simple and effective way to reduce serum unbound bilirubin. At present, the commonly used method in China is blue light irradiation. The newborn is lying in a phototherapy box, and both eyes are protected with black goggles to prevent damage to the retina. Sensitive fillings are covered with diapers, and the rest are exposed. Irradiate with single-sided light or double-sided light for 2 to 48 hours (generally no more than 4 days). The treatment can be stopped until the bilirubin drops below 7 mg/dL when conducting continuous or intermittent irradiation.

Safe and efficient light source-sufficient and uniform light, adjustable light intensity: -The emitted main radiation spectrum is between 400nm~550nm -Large disc: increase the light area, while ensuring sufficient and even light sources, improving curative effects -Multi-point LED light source: more than 500 lamp beads are evenly distributed, even if you look directly at it, it will not dazzle the eyes; provide high-intensity cold light source to treat light, reduce the impact of heat conduction on children

Long service life, high cost performance: -The service life of LED lamp beads is up to 10000hrs -Flexible combination: It can be matched with a variety of incubators and warming stations to reduce mobile touch

More precise bilirubin irradiance: -0~99% adjustable light intensity

Fanless ultra-thin closed design: -Reduce noise stimulation to children, do not disrupt laminar flow, and reduce hidden dangers of infection; easy to move, comfortable to look and feel, and no dust accumulation

Cluster Blu-ray Controller: -Easy to operate, timing, and displaying cumulative time, reducing the burden of medical operations

4 Factors to Consider When Choosing a Glucose Meter

Blood glucose meters are compact, computerized devices that measure and display your blood glucose level. It is specially helpful to use for people who have diabetes. Many types of blood glucose meters are available for at-home use. These range from basic models that only read blood glucose levels to more advanced versions that offer features such as memory for storing information. How should we choose a glucose meter?

There are few aspects to consider when choosing a blood glucose meter:

Accuracy

Medical-grade testing equipment will ensure the accuracy of the measurement results. According to the national standards, when the blood glucose value is ≥4.2mmol/L, the error range is within 20%. However, it is recommended to compare the test results with the hospital laboratory test results and always refer to the hospital test results.

Heal Force GUC-1ble is a device which provides blood glucose, uric acid and cholesterol analysis. It is certified that its measurement data is accurate by the national second-class medical device registration with the medical grade standard. The measurement results can be used as references for daily monitoring of blood sugar and other health conditions, as long as the device is operated correctly, the test strip is not expired and damp-free.

Functional Diversity

When choosing a glucose meter, in addition to the accuracy of measurement, it is necessary to compare the diversification of its functions, such as the number of supported measurement values, data storage capacity, and so on.

Heal Force blood glucose, uric acid and cholesterol analyzer GUC-1ble can automatically identify three different test strips of blood glucose, uric acid and cholesterol. Through manual coding adjustment, it can accurately measure the the values of blood glucose, uric acid and cholesterol of the human body. It is widely applicable to people with diabetes, obesity, gout and other chronic disease.

Each time you open a new pot of test strips you will need to recalibrate your meter. It may sound like a bit of a chore, but it is like when you are making a cake, you need to zero out the scales before you start doing all the measurements. If the scales change each time you weigh out your ingredients, at the end you will get a odd cake. Therefore, calibration removes the margin of error when possible. It is important to get your blood sugar readings as close to accurate as is possible.

Although blood test meters are commonly used, the technology used is still highly sensitive. Additionally, in the production of the blood test strips, the differences in product raw materials and production conditions (temperature and air temperature during production, etc.) makes the different batch of test strips different in reactivity. Therefore, a sample of each batch is taken and tested against a standard solution, the reading from the test is then given as a code number, thus the code number in entered into your meter which will recalibrate your meter correctly for that set of strips.

Data Accessibility

Under the influence of the Internet of Things integrate with medical health, data communication between different devices has becoming more and more important. The blood glucose meter with intelligent data transmission function is more suitable for people’s lives. Using mobile phones and other devices, you can easily retrieve historical records and intuitively understand the recent history over a period of time.

It is easier for doctors to retrieve your measurement and contruct suitable diet, exercise plan for you.

Heal Force GUC-1ble blood glucose, uric acid and cholesterol meter can automatic store test data, transmit measurement data via Bluetooth, enjoy the intimate service of Heal Force smart APP, , farewell to traditional paper records, it also can automatically generate blood glucose, uric acid, and cholesterol data reports/trends. Analyzing graphs is a good way to help patients understand their own health conditions in daily life.

After-sales Service

The blood glucose meter is not a disposable item, so the after-sales experience has become particularly important. As a professional team focusing on medical and health for more than 30 years, Heal Force after-sales service team has always adhered to the service principle of “attentiveness, concentration, consideration, peace of mind, and satisfaction”.

How to build a comprehensive vaccine cold chain storage solution?

The current global demand of COVID-19 vaccine has reached 12-15 billion. As the successful development of COVID-19 vaccine on a large scale this year, its implementation is inevitably facing a huge test on the vaccine cold chain storage, transportation and handling globally. COVID-19 vaccines with an ultra-low temperature cold chain profile pose several challenges for many countries and remote areas.

Specially, in many developing countries, the technologies are sparse, it is an inflection point for these countries to invest and increase in their cold chain abilities. Like the Pfizer-bioNTech COVID-19 vaccine currently has the most difficult storage requirement of any other vaccines, with a recommended temperature of minus 70 degrees Celsius, which has raised concerns that it won’t be a realistic fit for a rollout in most African cities. However, reported by devex.com that Africa CDC is acting to purchase more ultra-cold storage freezers to increase the cold chain capacity in order to cope with the demand of COVID-19 vaccine. 

By understanding about vaccine cold chain, we know that it involves with a set of strict rules to ensure vaccine transportation within proper temperature handled by distributors from manufacturer to facilities. It is a shared responsibility amount manufacturers, distributors, public health staff, and health care providers to ensure vaccine quality and maintaining the cold chain for the COVID-19 vaccine.

Vaccine distribution in each country generally uses urban-centered approach from central cities national/provincial, region, to health facility. Each level has a different emphasis on vaccine circulation tasks.

The national level focuses on centralized storage and distribution to various regions.

The regional area generally focuses on the management of regional vaccine storage.

The distribution of community hospitals and part of the inoculation work.

The health facility as the final stage is responsible for the limited amount of storage and inoculation of vaccines covering the community and outrage service to remote areas.

According to the distribution, Heal Force provide vaccine cold chain storage solution as illustrated below.

TOPSUN 7060 | Lighten Your Operating Room Vision

With the development of medical technology and the increasing demand for clinical surgery, the requirements for shadowless surgical lights in various operations are getting higher and higher. In the new era, operating room clinics have put forward very strict parameters such as the illumination, color temperature, and color rendering index of shadowless lights.

Heal Force launched the TOPSUN series of operating lights. The color temperature is adjustable in 10 levels, and the adjustment range is 3650K-5000K. It allows doctors to freely adjust the color temperature when facing different operations or different surgical sites, and restore the true color of human tissue.

TOPSUN Series Operating Light

10-level Color Temperature Adjustment Light sources with four colors ( Green, Amber, Red, and Warm/Cold/White) high CRI up to (Ra>=95). Meanwhile, the New Light Source requires fewer LEDs to reach an ideal illuminance with lower irradiated heat. The ten-level adjustable color temperature of 3650k-5000k supports doctors to distinguish different tissue types more easily, with less fatigue and more concentration, especially during long-lasting procedures. Ambient Light Mode The chief surgeon spends a long time indoors, which requires the surgical lights to maintain a relatively comfortable lighting environment. When performing minimally invasive surgery and endoscopic surgery, TOPSUN series lights can quickly reduce the illuminance, make the light softer and more comfortable, and make the imaging effect of the operation screen better.

Automatic shadow compensation

During the operation, the doctor’s head and body movements may block the lights and create shadows. TOPSUN Series features an Automatic Illumination Control System that senses the position of the surgeon’s head so as to achieve an excellent shadowless effect by automatically reducing the light bulb illuminance in the blocked area and increases illuminance in other areas. The temperature rise of the surgeon’s head is also lowered to assist the carrying out of the operation.

Wireless Inductive Dimmable

The Development Status of IoT Health Industry in China

The global Internet of Things (IoT) market was valued at $44.5 billion in 2018 and is expected to grow to $254.2 billion in 2026, according to AllTheResearch.  

In China, the development of IoT health industry has been very large. With the rapid development of mobile Internet and deployment of 5G networks, it ranges from functional smart wearable sensors and  in-home care, to community remote health monitoring and in-clinic/in-hospital management. The integration of health IoT operating devices such as smart watch, smart medicine chests, IoT medical equipment, smart robots, smart pharmacies, and health huts are widely used in different places nowadays. Concerns have gradually shifted from how to maintain health of individual patient, to how to improve services in the medical and health field.

Heal Force Health Management Workstation and Hub

The development of the IoT system has already penetrated into our lives. In the case of the epidemic that has profoundly affected the global medical and health industry in 2020, the Shanghai Public Health Clinical Center has used a continuous body temperature sensor based on the Bluetooth protocol to help fight the spread of the new coronavirus.

Doctors use multiple Bluetooth bio-sensors to collect patient vital signs data at the same time and send them to the central management system. Medical staff monitor their vital signs, reducing the need for routine physical examinations of patients, thereby reducing the communication time between patients and medical staff. The possibility of cross-infection can block the transmission of infectious diseases.

The IoT system has huge development prospects in life and has relatively mature practical solutions. The release of the “Healthy Internet of Things White Paper” in China will bring a more complete and complete normative reference to the health of Internet of Things industry, and promote the healthy development and progress of the industry.
