Design Considerations (Parameters) in Designing Wearable Medical Devices
Designing wearable health devices requires careful consideration of various parameters to ensure their effectiveness, comfort, and safety. Some key design considerations for wearable medical devices include:
Ergonomics and Comfort
The device should be ergonomically designed to fit comfortably on the user’s body for extended periods. The choice of materials, weight distribution, and shape should minimize discomfort and skin irritation.
For example - in the design of a wearable insulin pump, the device needs to be worn consistently for effective glucose management. If the pump is not ergonomically designed, with consideration for factors like weight distribution and ease of movement, it could lead to discomfort and skin irritation for the wearer.
Sensor Accuracy and Reliability
Calibrated and validated sensors ensure that the device provides accurate measurements and data.
User Interface and Interaction
The design of the user interface must prioritize intuitiveness and ease of navigation, particularly for older individuals or those with physical limitations. The incorporation of user-friendly buttons, touchscreens, or voice commands should ensure accessibility for all users.
In the case of wearable heart rate monitors, a clear and intuitive display, along with user-friendly controls, enables individuals to easily access their heart rate data during various activities.
Connectivity and Data Transfer
Seamless connectivity to smartphones, tablets, or cloud platforms is vital for data transfer and analysis.
Data Security and Privacy
Wearable medical devices collect sensitive health data, necessitating robust encryption and data protection measures to safeguard user privacy and comply with data protection regulations.
Water and Dust Resistance
Many wearables are exposed to various environmental conditions, so they should be designed with appropriate water and dust resistance to ensure durability and longevity.
Adherence and Wearability
Design features that promote user adherence, such as easy on/off mechanisms, adjustable straps, or interchangeable accessories, can encourage consistent device usage.
We worked with a wearable respiratory monitor for patients with chronic lung conditions. The device needs to be water and dust-resistant, adhere comfortably to the skin, and be wearable throughout various activities. Our team collaborated with developers to ensure the selected appropriate materials, have appropriate durability and comfort as per applicable standard requirements. We guided the integration of specialized adhesives that maintain a secure fit even during physical exertion.
Power Management and Battery Life
Efficient power management is essential for wearable devices. Longer battery life or alternative power sources, such as solar or kinetic energy, can enhance device usability and reduce the need for frequent recharging.
Medical Grade and Regulatory Compliance
Depending on the device’s classification, manufacturers must adhere to relevant medical device regulations and standards, ensuring compliance with safety and performance requirements.
While using a wearable ECG monitor, patients need continuous heart monitoring, but frequent recharging can disrupt usage. While the company was struggling to understand regulatory expectations, Elexes collaborated with engineers to assist them in implementing power-saving features, like intelligent sleep modes and low-energy Bluetooth connectivity from a regulatory expertise standpoint.
Interoperability and Compatibility
Wearable devices may need to integrate with other medical devices or health platforms. Design considerations for interoperability and compatibility are essential for seamless data exchange.
Imagine a hospital that uses a comprehensive Patient Monitoring System to track vital signs and provide real-time data for patient care. The PMS consists of various interconnected medical devices, including Vital Sign Monitors to measure a patient’s vital signs, such as heart rate, blood pressure, and oxygen saturation, Central Monitoring Station to collect data from vital sign monitors and displays it in real-time for healthcare professionals to review, and Electronic Health Records (EHR) System to store patient records, including historical medical data and current vital signs.
What are the ramifications of not registering a wearable medical device?
Failing to register a wearable medical device can have serious consequences for both the manufacturer and the users of the device.
The ramifications of not registering a wearable medical device can vary depending on the country or region in which the manufacturer intends to market and sell the device.
Here are some potential ramifications:
Legal Consequences and Market Access Restrictions
Selling an unregistered medical device can lead to legal penalties, fines, or even criminal charges and devices shall be barred from entering the market.
Loss of Consumer Trust
Operating without proper registration can damage the reputation and consumers may lose trust in the device’s safety and effectiveness, impacting its sales and market acceptance..
Product Recall or Seizure and Patient Safety Risks
Regulators can recall products or seize unregistered medical devices if found on the market. This can cause financial losses and harm to users if the device is risky.
Competitive Disadvantage
Other registered products may have an advantage in terms of market access and credibility.
Conclusion
Wearable medical devices have ushered in a new era of personalized healthcare, empowering individuals to take control of their health.
