SENSOR, SENSOR PAD AND SENSOR ARRAY FOR DETECTING INFRASONIC ACOUSTIC SIGNALS

摘要

A sensor, sensor pad and sensor array for detecting infrasonic signals in a living organism is provided. The sensor, sensor pad and/or array can be utilized for detecting, determining and/or diagnosing level of stenosis, occlusion, or aneurysm in arteries, or other similar diagnosis. The sensor can include unique circuitry in the form of a piezoelectric plate or element sandwiched between two conductive O-rings.

主权项

1. A disposable sensor pad for transmitting acoustic signals from a body to a sensor comprising a circular disk of a low durometer value material having an upper contacting portion having a forward facing surface for contacting a body, wherein the upper contacting portion includes a circumferential side wall and a circular upper surface and a bottom portion having a flat circular surface connected to the upper contacting portion for contacting a sensor element, a circumferential concave groove, and a circumferential lip on the outer portion of the circumferential concave groove; wherein the forward facing surface is suitable for contacting a body and the bottom portion is suitable for being positioned onto a piezoelectric element for sensing acoustic signals; wherein the bottom portion of the disposable sensor pad does not flex upon a force being applied to the forward facing surface.
