Noise Rejecting Electronic Stethoscope
The U.S. Navy seeks to commercialize through patent licensing an acousticelectronic stethoscope that selectively amplifies sounds of medical importance while suppressing environmental background noise.
The Naval Submarine Medical Research Laboratory in Groton, Connecticut, has developed a unique and effective device for improving the ability to transmit required sounds in noise-laden environments. This technology uses a combination of structural and electronic components that maximizes the signal to noise ratio. The stethoscope includes a novel diaphragm with dual piezoelectric sensor elements with opposing polarity and is enclosed in a convenient water-resistant housing.
- Ability to hear abnormal heart and lung sounds in a noisy environment
- Ability to provide quality care and confident diagnosis
- Delivers clean electronic output for telemetry, archival storage and acoustically-based diagnostic analysis
- Simple design is made to be very durable and water-tight
- Easy to operate
- Cost competitive with competing devices
The Navy has developed, prototyped, and successfully tested a medical stethoscope that provides statistically significant, substantial improvements when compared to existing technologies. The device was ruggedized for a US Marine Corps field test and additionally tested on HSV-2 Swift by US Navy medical staff. Interested companies may review additional technical and performance details from the laboratory or receive a demonstration of the technology. Published US patent publication number 2008/0137876 is available for licensing.
