Assignee: ENTAC MEDICAL, INC.
Field: Medical technology (Instruments)
Classification: CPC A | IPC A

Claim 0:
1. An intestinal audio analysis device comprising:
a patient interface adapted to attach to a surface of a patient's abdomen;
a diaphragm adapted to vibrate in response to intestinal sounds to create acoustic pressure waves which amplify the intestinal sounds made within the patient's abdomen;
an acoustic chamber adapted to receive the acoustic pressure waves caused by diaphragm vibrations which amplify the intestinal sounds;
a primary audio collection device located in or near the acoustic chamber;
a secondary audio collection device;
a housing comprising a computer,
wherein the computer, the primary audio collection device, and the secondary audio collection device are contained within the housing;
a memory comprising one or more algorithms,
wherein at least one of the one or more algorithms analyzes collected audio data from the acoustic pressure waves collected by the primary audio collection device for false signals due to ambient noise,
wherein at least one of the one or more algorithms analyzes two or more spectral event values of the collected audio data over time,
wherein, after the collected audio data is analyzed for the false signals, at least one of the one or more algorithms serves to produce a slope of a linear regression analysis of the two or more spectral event values of the collected audio data over time,
wherein the slope of the linear regression analysis is compared to a pre-determined slope threshold so as to make a binary prediction regarding gastrointestinal impairment; and

a user interface comprising a display.
