My worker firmware works! It flashed itself over, now just to add some roll back, security, and validation features. But effectively this means I never have to plug in another ESP32 to send them firmware. I can just tell them to post to MQTT from the worker firmware for logging and post the firmware binary to my local file server. This makes my life so much easier while building out this mesh of meshes multi-protocol com lib. Hell yeahhh

A Comprehensive Guide for Embedded Software Development for Medical Devices 

As a reality check, the embedded software development life cycle of a medical device is not only challenging, but it is also sophisticated in regard to the value proposition it presents to the healthcare payers and patients. Consequently, as the field of medicine continuous to evolve, these tools become more complex as their operations are managed by embedded software which needs to be integrated with the system in a way that guarantees safe and effective operation. This in-depth tutorial will guide you through the development embedded software for medical devices and all regulatory considerations that must be addressed.

Grasping the Regulatory Framework

Manufacturers of medical devices will always be bound by the numerous laws from the Federal Drug Administration (FDA) concerning effectiveness and safety of medical devices. Starting March 2023, the FDA began restricting submissions of Software Bill of Materials (SBOM) unless there was a set cybersecurity strategy. By October 2023 the FDA started refusing to accept submission of devices that had cyber security problems.

The regulatory landscape requires manufacturers to:

Implement a risk-based approach to software design and testing Conduct thorough validation of software functionality and security

Ensure devices can detect and respond to security incidents

Establish processes for monitoring and reporting security issues

Conduct ongoing testing throughout the device's lifecycle

Key Components of Embedded Medical Device Software

Hardware-Software Integration

In medical devices, embedded systems must achieve full intergration of hardware parts and software. This is necessary to guarantee that the medical devices operate as needed and that safety regulations are satisfied.

Real-Time Operating Systems (RTOS)

Many medical devices use Real-Time Operating Systems because they require some degree of waiting time to perform an important task. Such OS’s are essential in time-sensitive operations. For embedded medical devices, RTOS frameworks like FreeRTOS and Zephyr are routinely deployed.

Software Architecture

The structure has to be modular, so that later maintenance, testing, and validation would be easier. That also helps meet regulatory standards because tracking requirements to be enacted is simplified.

The Development Process

Establishing a Regulatory Strategy Early

Prior to commencing any developmental work, formulate and put in writing a regulatory strategy that is aligned with the device's capabilities and goals. This becomes particularly critical in the case of Software as a Medical Device (SaMD), wherein modifying software becomes relatively easier than changing a hardware component.

Selecting the Right Development Team

Select the relevant personnel from the software policy team having working knowledge in cyber security, more so, if drastic changes are anticipated post initial launch of the product. Engage the services of engineers specialized in software development of medical devices as they have working knowledge of the required documentation for the device regulatory processes.

Programming Languages and Tools

Common languages used in embedded medical device development include:

C: Efficient and suitable for low-level memory management

C++: Provides object-oriented features for complex systems

Assembly: For performance-critical applications requiring direct hardware access

Rust: Offers memory safety features for developing secure systems

Implementing Security by Design

Security is not an add-on but a fundamental aspect of medical device software development. The FDA requires manufacturers to:

Conduct secruity risk assessments to identify potential vulnerabilities

Implement security controls to mitigate identified risks

Design software to be resilient against potential attacks

Ensure the ability to detect and respond to security incidents

Testing and Validation

Comprehensive Testing Approach

Testing should cover every aspect of the software, including:

Unit testing for individual components

Integration testing for combined components

System testing for the entire device

Performance testing under various conditions

Security testing to identify vulnerabilities

Documentation Requirements

Thorough documentation is essential for regulatory compliance. This includes:

Design specifications

Risk assessments

Test protocols and results

Validation reports

User manuals and technical documents

Post-Market Requirements

Getting regulatory clearance is just the beginning. Once your device is on the market, you must:

1. Maintain annual Establishment Registration

2. List your device(s)

3. Implement and maintain Quality Management System (QMS) processes

4. Document changes to software and assess regulatory impact

5. Be prepared for FDA audits

6. Run postmarket cybersecurity processes including periodic penetration tests and vulnerability scans

7. Conduct postmarket surveillance

8. Produce Unique Device Identifiers for new versions

Managing Software Updates

Yes, you can update your software after FDA clearance, and in fact, the FDA expects you to provide cybersecurity updates. However, significant changes may require a new 510(k) submission, possibly including new clinical or performance data.

Strategic planning around feature development is crucial. Consider creating key features that FDA needs to evaluate in version 1.0, then have your engineering team work on version 1.1 features while waiting for FDA review.

Best Practices for Success

Optimize code for performance, power consumption, and memory usage

Implement robust error handling mechanisms

Reuse code when possible to reduce development time

Provide thorough documentation for maintainability

Perform comprehensive testing to ensure code meets requirements

Raise sufficient funding for clinical performance validation, non-clinical testing, software documentation, and cybersecurity.

Conclusion

A greener tomorrow starts with better healthcare today, and embedded software for medical devices is at the forefront of this transformation. By integrating robust security measures, following regulatory guidelines, and implementing best development practices, manufacturers can create safe, effective medical devices that enhance patient care while maintaining compliance.

Let's build smarter, develop better, and create medical devices that care for both patients and healthcare providers. The truth is, embedded software development for medical devices is complex but essential for advancing healthcare technology and improving patient outcomes.

好きだから -- ぼ虹の日 edit

This is very self indulgent and I wasn't even expecting to finish it in time for boniji day. Maybe I just love the pairing so much I wanna make something for it also cuz I still haven't drawn anything about them lately cuz depression go brrrrr

This is initially from Nijika's POV towards Bocchi but some lyrics strayed from that especially the dog part and the last one. But this could also be from Bocchi's POV visualizing Nijika's feelings about her since the edit did start and end with Bocchi in it so...yeah that's how this edit is interpreted (also I kinda got stuck of not knowing what clips that could fit in some parts so ignore if most of the clips are from episode 8)

Btw at the 「またね」 and 「また明日」 part, I was originally going to put the same lines by both Nijika & Bocchi from the show but it sounds out of place so I scrapped it. Tho if I'm better at editing I could make it work and blend it along with the song without it sounding weird (but I'm not :P)

Another thing is that although the lyrics did say 授業 (class) / 放課後部 (after-school club) / LINE in some parts, I changed it to バイト (part time job or in this case I chose work) / 帰宅部 (go-home club) / LOINE to fit the terms in BTR
