Disposable sensing device with contaneous conformance
First Claim
1. A patch sensing device for picking up multiple acoustic output signals in a subject'"'"'s anatomy and for triangulating the acoustic output signals so as to pinpoint a location and source of the acoustic output signals in the subject'"'"'s anatomy,wherein the acoustic output signals have a location and source in the subject'"'"'s anatomy,wherein said patch comprises a sheet of compliant material which can be conformed to a shape of a surface of a portion of the subject'"'"'s anatomy above the subject'"'"'s heart valves,wherein the sheet comprises at least two sensors in laterally spaced apart association therewith,wherein each of said laterally spaced apart sensors has a diaphragm formed from a piezoelectric polymer transducer material, andwherein said laterally spaced apart sensors are positioned to cover the subject'"'"'s heart valves when the patch is conformed to the shape of the surface of the portion of the subject'"'"'s anatomy above the subject'"'"'s heart valves.

Abstract
The present invention relates to a sensing device for capturing acoustic heart sounds. The sensing device has a diaphragm formed from a piezoelectric transducer material which generates excitation signals in response to acoustic and vibratory energy outputs. The sensing device includes metallization layers on the diaphragm for receiving and transmitting the excitation signals to an output display device via associated electrical contacts and electrical leads and also includes a layer of adhesive material for coupling the sensing device to the subject. The sensing device further includes snap connectors for allowing the device to be quickly disengaged from electrical leads and discarded. A patch sensor device is disclosed which enables acoustic outputs to be triangulated and pinpointed.
