Key Considerations for Integrating Wireless Technology in Medical Devices

Significant opportunities exist to incorporate wireless technology into medical devices. Wireless technology increases the effectiveness of countless every day functions. While some simply are about the convenience factor, like being able to quickly transmit patient records from one hospital to another via email, others have the power to be lifesaving. Medical device manufacturers know that there is significant opportunity to incorporate wireless technology into medical devices. However, design engineers who are extremely knowledgeable about the design of medical devices face a number of challenges in marrying off-the-shelf wireless chipsets with proprietary medical devices in development.

Micro-Endoscope as Thin as a Human Hair

Single fiber endoscope increases resolution fourfold over previous similar devices. Engineers at Stanford University have developed and demonstrated a prototype single-fiber endoscope that, they say, quadruples the resolution over existing designs, which might lead to the development of needle-thin, minimally invasive endoscopes able to view features out of reach of today’s instruments.

Managing Post-Traumatic Pain with Ultrasound Neuromodulation

This ultrasound technique is an alternative to narcotics for treating pain from acute trauma. The objective of this effort was to demonstrate the feasibility of using ultrasound induced neuromodulation (UNMOD) to manage pain. Pain management for acute trauma is generally accomplished with narcotics, which is less than ideal in a battlefield scenario. The technology of peripheral ultrasound neuromodulation (PUNMOD) offers several advantages over narcotics and current methods of neurostimulation. PUNMOD has the potential to be highly portable as a battlefield analgesic, and has the advantage of leaving the patient’s cognitive abilities intact. In addition, PUNMOD does not carry with it the risk of abuse or the need for the surveillance that is associated with pharmaceutical analgesics.

Self-Charging Power Cell for Small Devices

A hybrid power cell uses a new technique for electrical charge conversion and storage. Scientists at Georgia Tech say that they have developed a new self-charging power cell technology that directly converts mechanical energy to chemical energy. Then, the power is stored until it is needed to generate electricity. This hybrid generator- storage cell utilizes mechanical energy more efficiently than systems using separate generators and batteries, they say.

Integrating Electrical Systems into 3D Mechanical Models

Real-time integration of 2D schematics and 3D models allows mechanical and electrical teams to better collaborate and deliver more accurate designs. Product development teams are under increasing pressure to engineer more complex products that combine numerous electrical systems within a single design, including visual interfaces, power systems, logic controllers, complex wiring and harnesses. Simplifying the design of these electro-mechanical systems using intelligent design tools, and a shared, comprehensive parts database, medical device designers are able to achieve significant cost savings. These savings are multiplied when this electrical design work is done in perfect synchronization with the mechanical and industrial design teams using a shared data model.

Lithium Batteries for Medical Applications

Recent advances in lithium technology have increased the variety of commercially available batteries. The element lithium possesses fundamental properties that make it ideal for use as the anode in both primary and rechargeable batteries. Vendors have paired the popular lithium anode with a variety of cathode and electrolyte materials, resulting in the wide choice of different chemistries available today. This article discusses the types of primary lithium batteries commonly used for medical applications and introduces a new type based on recent innovations in materials and manufacturing processes. Information about the basic properties, advantages, and disadvantages are provided for each battery type.

VA Developing New Heat- Enhanced Pulse Ox Device

Probe improves accuracy in reading blood oxygen saturation levels in patients who are harder to read due to low core temperature. Pulse oximetry has gained widespread clinical acceptance as a standard patient vital sign measurement because it can give clinicians an early warning of low arterial blood oxygen saturation levels, or hypoxemia. Conventional pulse oximetry is subject to technological limitations that reduce its effectiveness and the quality of patient care. To mitigate the limitations of current technologies, the U.S. Department of Veterans Affairs (VA) has developed a novel device that provides reliable pulse oximetry measurements of oxygen saturation and heart rate in patients with low body temperature due to vasoconstriction and low blood perfusion.
