US 2023/0142937 A1 · ELECTRONIC STETHOSCOPE

Abstract

An electronic stethoscope uses a contact sensor to confirm continuous contact with a patient. A recording of body sounds is begun while a timer is initiated. Upon a signal from the timer, recording is terminated. The duration of the timer may be set remotely by a practitioner. Additionally, the contact sensor may require a minimum level of force as an implicit indication that the stethoscope is firmly stationary. Once a valid measurement is recorded, it is analyzed in comparison to a baseline. Artificial intelligence is used to select the appropriate from a database of sampled data. Bootstrapping is used to develop additional data sets and Random Forest algorithm is used to select the appropriate baseline from the data. The current recording is analyzed with respect to the AI selected baseline. A display on the electronic stethoscope displays analyzed results as well as providing the visual aspect of a user interface.

Dependent claims

An electronic stethoscope for recording sounds produced from within a body, the electronic stethoscope comprising:

a housing;
a diaphragm at a surface of the housing;
a chest piece behind the diaphragm, the chest piece having an aperture through it;
a sound sensor within the housing positioned to receive sound from the aperture in the chest piece;
a programmable processor capable of executing machine readable instructions;
a display screen;
a battery;
user controls;
and,
a contact sensor proximal to the diaphragm;
wherein,
the programmable processor monitors the contact sensor for a contact signal indicating that the diaphragm is in position and the programmable processor operates a timer to control the duration of a recording from the sound sensor.
