Using UVC LEDs to Reduce the Spread of Healthcare Acquired Infections (HAIs)

According to FDA, contact with infected objects and medical devices is a leading cause of healthcare associated infections (HAIs). Reducing HAIs by better understanding the effectiveness of antimicrobials, sterilization, and reprocessing of medical devices is one of the agency’s regulatory science priorities for 2017.

PTC Heater Brings Greater Control for Hand-held Medical Devices and Disposables

Point of Care diagnostics devices, whether handheld or single-use, often require a brief application of tightly controlled heat. The disposable nature of these devices requires a low-cost component capable of delivering that heat reliably and safely. Heatron's new PTC heater solution uses a polymer-based heater technology that controls heat to within ±2°C of the target temperature, and reduces unit cost by eliminating sensors and applied controls.

High-Quality Tissue Formation Method

This technology could be used in research and development, pharmaceutical development, regenerative medicine, and drug screening and testing.

NASA's Johnson Space Center seeks interested parties for the commercialization of the High Density Spot Seeding (HDSS) method to create 2D and 3D tissue models. This method can potentially be used to develop tissue models for a variety of applications, including wound treatment, therapy, and tissue modeling of skeletal muscle, cardiac muscle, nerve, and bone. The HDSS technique has an easy four-step method that does not require expensive reagents, such as specialized serum or growth factors, and compared to traditional methods, HDSS has the potential to yield superior-quality tissue samples.

Filtering Molecules with Nanotube Technology

Innovators at NASA's Johnson Space Center have developed a filtration device to eliminate contaminants from water supplies. Originally developed to purify waste-water for reuse aboard the International Space Station, the innovation is applicable to numerous situations on Earth where there is a need to collect potable, medical-grade water from a contaminated water supply. The unique aspect of the technology is its use of acoustics, rather than pressure, to drive water through small-diameter carbon nanotubes. The invention requires less power than conventional filtration systems, and is well-suited to a variety of water processing needs.

Algorithm Measures Range of Motion and Applies Eccentric and Concentric Loads During Exercise

Microprocessor-controlled exercise equipment that uses a servomotor has the capability to adjust the applied resistive load based on position, velocity, and acceleration. One method of applying the resistive load consists of applying a greater load during the eccentric phase of the exercise motion (muscles actively lengthening) than during the concentric phase of the motion (muscles actively shortening). This technique, called eccentric overloading, can improve the benefits of a strength training session significantly. Although the exercise device can alternate between concentric and eccentric loading based solely on the direction of the bar movement, this is undesirable for several reasons. First, when the velocity is close to zero, the system would rapidly switch between the eccentric and concentric loads. Second, if the exerciser is unable to complete a lift with the concentric load and wishes to lower the bar, the system would apply the high eccentric load, which is highly undesirable. Thus, it is necessary for the system to know the limits of the movement (range of motion, ROM) so that the system can identify when the user has completed the lift and the eccentric load can be properly applied.

ISO 11135:2014 Changes – Are You Prepared?

ISO 11135:2014 (Sterilization of health-care products - Ethylene oxide - Requirements for the development, validation and routine control of a sterilization process for medical devices) was originally published in August 2014. As the end of the 3-year transition period approaches, the specifications in the previous edition will no longer apply.

Designing for Mechanical and Signal Integrity in Handheld Medical Treatment Applications

Handheld medical devices must perform across a wide range of device specifications and end-user environmental conditions. Mechanical and signal integrity of cable components is especially important for high-level performance, accuracy, durability, longevity, and user satisfaction. A great variety of insulating and jacketing material options exist for wire and cable in medical electronics. Performance factors that affect material selection decisions include biocompatibility, disinfection and sterilization compatibility, revision control assurance, environmental regulatory compliance, aesthetics, flexibility, durability, and cost. Subtle differences in priority may result in significant differences in product design, as well as overall cost.
