Unpacking the Complexities of Portable Medical Devices: A Deep Dive

One of the challenges faced by portable medical devices today is that they need not only remote connectivity capabilities but also the maintenance of quality and responsiveness of all gathered data. Furthermore, portability is a significant consideration. The term “portable” in portable medical devices is primarily in contrast to the large-scale medical equipment used in hospitals, most of which are wheel-mounted and cumbersome to move. Today’s “portable” medical devices are not just transport-friendly; many are even “wearable.” These transformations pose multiple challenges for designers.

Upon “dissecting” portable medical devices, several functional blocks can be identified that are common across most portable consumer and home-use medical devices. These include: biometric sensors, amplification and analog-to-digital conversion of sensor input, battery and power management, low-power microcontrollers or digital signal processors (DSP), user interface or display, human-machine interface (HMI), and data interfaces (both wireless and wired).

Microcontrollers (MCU)/DSP:

Portable medical devices produce a considerable amount of raw data. The ability to store and process data, recognize changes, provide feedback, connect with large systems, and execute diagnostic algorithms are typically essential features of system microcontrollers. However, ultra-low power consumption and high performance often clash, making it vital to balance system processing needs with power constraints. Key design considerations for portable medical devices are low power consumption, primarily to prolong battery life. Other requirements include faster time-to-market, cost-efficiency, reliability, compact size, and higher integration.

Battery and Power Management:

For portable medical devices, simple systems with very low power consumption can use disposable batteries, while larger systems might need various sizes of rechargeable batteries and battery packs. When medical systems are needed, there often isn’t the luxury of time to wait for charging. Dynamic power path management and other features can charge the battery independently while powering the system, eliminating wait time for battery charging before operation. The lifespan of portable medical devices can range from a few days, months, or even several years.

With the maturation of lithium battery research and development technologies and the increasing mobility demands of portable medical devices, lithium batteries, boasting high voltage, high energy, and longevity, are gradually taking the lead in the medical device industry. These batteries enable medical devices such as defibrillators, monitoring instruments, ultrasound equipment, and infusion pumps to operate in locations distant from hospitals. It is precisely because of technologies like lithium batteries that 50-pound defibrillators can now be replaced with lighter, more compact devices.

Benefits of using lithium batteries in medical devices:

  • Excellent Safety Performance: Lithium batteries for medical devices adopt an aluminum-plastic flexible packaging, different from the metal casing of liquid lithium batteries. In potentially unsafe scenarios, liquid batteries can explode, while medical device batteries at most might inflate.
  • Slim Design: There’s a technical limitation for liquid lithium-ion batteries to be less than 3.6mm in thickness. However, medical device batteries face no such constraint even when they’re less than 1mm thick.
  • Lightweight: Lithium batteries for medical devices weigh 40% less than steel-shelled batteries of equivalent capacity and 20% less than aluminum-shelled ones.
  • Customizable Shapes: The shape of lithium batteries for medical devices can be altered based on customer needs. This flexibility allows for adjustments in battery thickness and form factor swiftly.
  • High Capacity: The capacity of lithium batteries designed for medical devices is 10-15% higher than steel-cased batteries of the same size and 5-10% more than their aluminum-cased counterparts.
  • Low Internal Resistance: Special designs can substantially reduce the impedance of the lithium battery, significantly enhancing its high-current discharge performance.

Touch Screen Control (TSC) is pivotal for the convenience of portable medical devices. It replaces traditional keyboards, significantly reducing the overall size of the device. TSC enables menu-driven function selection, fine-tuning of input/output data display, and magnification, significantly enhancing device usability. The electrostatic (ESD) handling capability of the chosen solution is an essential factor to consider when implementing TSC.

Sensor Interface and Signal Chain Technology:

The right signal chain is critical for temperature, pulse, glucose readings, and other biometric sensors. In most applications, designers strive to find microvolt-level signals amidst millivolt noise. Given the AC characteristics of the target signal, an amplifier that meshes well with a high-pass filtering scheme is necessary, coupled with a high-performance analog-to-digital converter.


The hallmark of portable medical devices lies in their low power consumption, reliability, and cost-effective sensor technology.
