Abstract
Abstract A method and a system for evaluation of a human disease by recording body sounds for extended periods of time by a microphone placed in contact with the body of the patient and using computer processing of body sound data to provide frequency domain and time domain sound amplitudes. A computer reads out a converted measurement of a sound taken by the microphone and places the data on the computer data bus for further processing. The method and system provide a diagnostic information on diseases, such as certain diseases of the gastro-intestinal tract and the heart, which generate abnormal body sounds and provide assessment of patient progress during treatment of such disease entities.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
130 words
A system for evaluation of a human disease associated with abnormal body sound production from body multiple organ systems, the system comprising a microphone device placed in contact with a patient's body; means for generating and amplifying an analog sound signal received from said microphone device; as frequency analyzer connected to said generating and amplifying means and including first means for separating the sound signal into various frequency bands in infrasonic and audible spectrums, second means for determining a sound amplitude in each frequency band, and means for digitizing the analog sound signal to obtain digital signals; and a computer for receiving said digital signals from said frequency analyzer and performing an average wave form analysis of said signals so as to provide time averaged calculation of body sound data.
Claim 2
Independent Claim
130 words
A system for evaluation of a human disease associated with abnormal body sound production from body multiple organ systems, the system comprising a microphone device placed in contact with a patient's body; means for generating and amplifying an analog sound signal received from said microphone device; as frequency analyzer connected to said generating and amplifying means and including first means for separating the sound signal into various frequency bands in infrasonic and audible spectrums, second means for determining a sound amplitude in each frequency band, and means for digitizing the analog sound signal to obtain digital signals; and a computer for receiving said digital signals from said frequency analyzer and performing an average wave form analysis of said signals so as to provide time averaged calculation of body sound data.
Claim 3
Dependent Claim
24 words
A system as set forth in claim 1, and further comprising means for generating time/amplitude plots arranged to provide evaluation of a human disease.
Claim 4
Dependent Claim
24 words
A system as set forth in claim 1, and further comprising means for generating frequency/amplitude plots arranged to provide evaluation of a human disease.
Claim 5
Dependent Claim
32 words
A system as set forth in claim 1, and further comprising means for identifying peaks in the body sound data arranged to provide amplitude, volume, width, and frequency patterns of the peaks.
Claim 6
Dependent Claim
37 words
A system as set forth in claim 1, wherein said frequency analyzer and said computer are adapted for analyzing bowel sounds and arranged to provide information for diagnosis and monitoring of certain diseases of the gastro-intestinal tract.
Claim 7
Dependent Claim
24 words
A system as set forth in claim 1, wherein said generating means includes an electronic amplifier connected to said microphone device via a cable.
Claim 8
Dependent Claim
18 words
A system as set forth in claim 1, wherein said separating means includes a bank of analog filters.
Claim 9
Dependent Claim
16 words
A system as set forth in claim 1, wherein said digitizing means includes an analog-to-digital converter.
Claim 10
Dependent Claim
23 words
A system as set forth in claim 1, wherein said computer is arranged so as to perform said analysis in the infrasonic range.
