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 an insulated human body immersed in a cold water environment is due to heat loss through respiration.

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.

Environmental Awareness Leads to PVC-Free Assemblies

Totally PVC-free products provide an environmentally safer alternative. Over the last several years, the medical industry has become more aware of the toxic side effects of polyvinyl chloride (PVC). The American Public Health Association passed a resolution in November 2011 urging hospitals, schools, and nursing homes to reduce the amount of PVC they use.

Prosthetic Foot Uses Unique Aerospace Material

A new space-age material creates a prosthetic foot that’s built to last. Formerly used only in the aerospace arena, Flexeon is a radical departure from the rigid carbon fiber materials found in most prosthetic feet. It’s a specially- formulated reinforced fiberglass material that is nearly indestructible, extremely flexible, and available exclusively on Ability Dynamic prosthetic devices, such as the RUSH™ foot. Flexeon underwent thorough and extensive testing for flexibility, material strength, and durability in prosthetic labs, as well as on patients aged 21 to 69 in clinical trials. The results of these tests and trials revealed that this high-tech material is three times more flexible than carbon and much more durable than current standard carbon fiber products.

Instantly Capture, Edit, and Store Medical Images via Online Applications

Online tool allows user to conveniently capture and manage images from medical devices. A new image capture software development kit (SDK), called the Dynamic Web TWAIN, allows the simplified creation of an online tool to manage images of patient records. It enables image application providers to deliver a method to capture images from medical devices, such as intraoral cameras and digital x-ray equipment, and then send the medical images to a central web server. Such medical image captures can be sent alongside a patient’s identification, results data, applied treatments, next visit schedules, and more. An SDK allows implementation within popular Internet browsers, including Internet Explorer, Chrome, Firefox, Safari, or Opera. (See Figure 1)

New Blood Pressure Connectors Prevent Misconnects

Fittings make quick connections easier and safer, even in low-light situations. Healthcare professionals use medical devices in a variety of settings and situations from urgent to routine. In an emergency, any sort of confusion, hindrance, or hesitation concerning the most minor detail or part of a device can mean a matter of life or death. As a result, there is a constant battle among medical device manufacturers to develop products with superior ergonomics, risk-free designs, and the ability to meet extensive technical requirements—all while maintaining a reasonable profit margin. In response to these concerns, Value Plastics has developed a new line of quick connect fittings. Their BPL Series of tubing connectors incorporates a number of features that are not only aimed at meeting engineers’ needs but also designed to ease users’ stress and frustration that can arise from use in critical situations.

Transferrable Sensor Tattoo Measures Metabolic Stress

Smiley sensor works like a temporary tattoo to detect disease. A medical sensor, that adheres to the skin like a temporary tattoo could make it easier for doctors to detect metabolic problems in patients as well as help coaches to fine-tune athletes’ training routines, say researchers at the Department of Physical & Environ mental Sciences at the University of Toronto, Scarborough, Canada (UTSC). The entire sensor was designed as a thin, flexible package shaped like a smiley face.
