Molded Interconnect Device Technology Enables Smaller Medical Devices
Posted in Electronics & Computers, Electronics, Manufacturing & Prototyping, Features, MDB on Monday, 01 March 2010
The need to minimize healthcare costs is creating greater demand for equipment that, among other things, improves and expands patient diagnostics, both inside and outside healthcare facilities. For example, portable medical instruments such as glucose meters, blood pressure monitors, and oxygen meters can be designed with communication capabilities to provide continuous information to caregivers almost anywhere. Smaller handheld devices can also improve various diagnostic procedures in dentistry and medical offices. In addition, these smaller portable devices can improve the quality of life for patients who use them. While such devices hold the promise of improved care at lower cost, they require advanced technologies that allow greater miniaturization to further improve portability and functionality.

RF/EMI Shields
Posted in Electronics & Computers, Electronics, Products, MDB on Monday, 01 March 2010
Photofabrication Engineering (Milford, MA) has introduced a line of EMI/RF shields with snap-on/snap-off covers, allowing access to components within the shields. The shields are designed to protect components from radio frequency/electromagnetic interference and environmental hazards, and to provide electrical grounding in medical and biomedical equipment. Standard forming tools are available in any size and shape to create covers that attach onto a fence, yet can be removed and replaced easily. The photochemically etched fences have grooves etched approximately 50% of the material thickness, so custom spring finger designs snap into them firmly. Shielding options for circuit board applications include one-piece or two-piece construction; standard base materials such as brass, tin, tin-lead, nickel, copper, and cold-rolled steel, all of which can be provided with solderable plating; and nickel-silver base material, which does not require additional finishing because it is already solderable.

This germicidal irradiation system eliminates airborne bacteria, molds, and viruses in one pass.

Ultraviolet germicidal irradiation (UVGI) technologies are being used as infection control devices, primarily in healthcare facilities. No standard exists, but the dose of UV and the airflow are critical to ensuring all contaminated air is treated. The UVGI process is mainly influenced by the microorganism population, the irradiation intensity, and the intimate exposure time to the lamps. This new technology enables the system to increase the intensity field or to improve the inactivation process, without adding more energy or increasing the output efficiency of the lamps.

Remote Diagnostic Technology for Hearing Assessment
Posted in Bio-Medical, Electronics & Computers, Electronics, Medical, Patient Monitoring, Briefs, MDB on Tuesday, 01 September 2009

Clinicians can remotely assess, diagnose, and remedy hearing loss.

Individuals with hearing loss need to have ready access to hearing screenings, assessments, treatment, and consultation. This diagnostic technology facilitates early detection and intervention of hearing loss. It allows for improved monitoring and expands service scope, reach, and access. By reducing or eliminating travel times, it is also a more efficient utilization of time for audiologists and professional staff. The tele-hearing device and protocol provides clinicians the tools and the ability to remotely assess, diagnose, and remedy hearing loss. This is accomplished either directly or indirectly by facilitating assistance to other less experienced clinicians remotely.
