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 Technology:
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.
Benefits:
- 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 Opportunity:
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.
