The Next Generation of Cold Immersion Dry Suit Design Evolution for Hypothermia Prevention

The system design recovers warm exhaled air and re-circulates it inside the suit. A body at sea is vulnerable to hypothermia, which often leads to loss of life. Hypothermia is caused by the differences between the core body temperature and the surrounding air and seawater temperatures. The greater the differences between the body core temperature and the sea temperature, the more rapidly the core body temperature will drop, and hypothermia can quickly set in. Heat loss is primarily caused by conduction of heat away from the body. Most cold immersion suits on the market are passive designs that only insulate the body against the cold, although some cold immersion suits use special materials such as paraffin to absorb heat and to radiate the heat back to the body. This new utility patent is an active design that relies on the lung’s role as an organic heat exchanger for providing deep body core heating of air. It is based on the fact that the greatest heat loss mechanism for insulated human body immersed in a cold water environment is due to heat loss through respiration.

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.

Fifty Years of Small Diameter High Quality Precision Tube Technology

Technology, applications, and materials evolve from analog meters to cutting edge medical devices. Over the past fifty years, thin wall small diameter precision metal tubing has undergone quite a transformation. From its use in the mid-1960s as pointers for analog meters, tubes have become essential components in the most cutting edge medical devices. To make that transition, precision tube companies have had to adapt to changing technology, applications, and materials.

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.

Hand-Based Biometric Analysis

Hand-based biometric analysis systems and techniques provide robust handbased identification and verification. An image of a hand is obtained, which is then segmented into a palm region and separate finger regions. Acquisition of the image is performed without requiring particular orientation or placement restrictions. Segmentation is performed without the use of reference points on the images. Each segment is analyzed by calculating a set of Zernike moment descriptors for the segment.

Choosing Chiller Pumps to Cool Medical Lasers

Medical lasers must be cooled either by premounted or portable chiller systems. Laser systems continue to grow in application use throughout the medical industry. Applications for laser systems include diagnostic analysis systems, DNA sequencing systems, dental cleaning and surgery, skin care, eye surgery, tattoo removal, and much more. These systems commonly require cooling of the laser and other electronic components either by air flow on lower power laser systems, or by fluid circulation/chiller systems on higher power lasers. Higher power laser require an increased level of cooling capacity that results in systems that provide several gallons per minute of fluid circulation. This increased flow rate will maintain the laser and other electronics at the proper operating conditions.
