Embodiment Construction

[0071] The preferred P2M system is a monitoring device with two main subsystems, one for measuring the signal and the other for processing the data into meaningful information.

[0072] figure 1 shows a schematic diagram of the system, while figure 2 A perspective view of the system is shown. First, the piezoelectric membrane, an electroactive fluoropolymer, converts mechanical energy such as motion induced by a heartbeat into voltage measurements that can support time-series analysis techniques. This voltage is then recorded and analyzed using a microcomputer control system, the reason for which is to distinguish the signal from background noise and display it on a screen or printout. Techniques such as pre-amplification and pre-conditioning using high-pass and low-pass filters reduce noise.

[0073] The piezoelectric material 1 used is the polymer polyvinylidene fluoride (PVDF), which can be formed into cables, films or thick tiles. PVDF piezoelectric films are environ...

Abstract

Passive physiological monitoring apparatus has a sensor for sensing physiological phenomenon and method converter converts sensed data into electrical signals and a computer receives and computes the signals and output computed data for real-time interactive display. The sensor is a piezoelectric film of polyvinylidene fluoride. Signals detected include mechanical, thermal and acoustic signatures reflecting cardiac output, cardiac function, internal bleeding, respiratory, pulse, apnea and temperature. The sensor may be an array provided in a MEDEVAC litter or other device for measuring acoustic and hydraulic signals from the body of a patient for field monitoring, hospital monitoring, transport monitoring, home, remote monitoring.

Description

Background technique [0001] It is imperative to minimize the time it takes to transport an injured soldier to an appropriate level of medical care to ensure that the wounded soldier receives timely treatment, which is critical to the survival of the wounded soldier. During this period, aeromedical care in the ambulance helicopter environment was often used to identify and transport casualties. [0002] Routine aeromedical evacuations conducted by military units, both in war and peacetime, expose patients and flight / medical personnel to noise or environmental stress and harsh surveillance conditions. As in the civilian community, military nurses rely on reliable and efficient monitoring equipment to provide accurate patient monitoring in a variety of settings, some of which are hostile and reckless to the use of traditional monitoring equipment. Although aeromedical escorts are a life-saving procedure for most, it is nearly impossible for medical personnel to monitor vital sig...
