Passive physiological monitoring (p2m) system

Abstract

Passive physiological monitoring apparatus and method has a sensor for sensing physiological phenomenon. The sensor is a piezoelectric film of polyvinylidene fluoride. A pad may incorporate the PVDF film. The film converts mechanical energy into voltage signals. A microcomputer is used for recording, analyzing and displaying data from the sensor for on-line assessment and for providing realtime response. The sensor may be an array of sensors provided in a MEDEVAC litter or other patient support for measuring acoustic and hydraulic signals from the body of a patient for field monitoring, hospital monitoring, transport monitoring, home, remote monitoring.

1 . Passive physiological monitoring apparatus comprising at least one sensor for sensing data by placing the at least one sensor on a body, a converter communicating with the at least one sensor for converting sensed data into signals, a computing device communicating with the converter for receiving and computing the voltage signals and for outputting computer data, and instrumentation communicating with the computing device for real-time interaction with the device and for display of the computed data.
