Abstract

A medical diagnostic and communications apparatus with audio output comprises an electronic processor for processing stethoscope signals and secondary audio signals. An electronic stethoscope sensor is contained within a housing for transducing body sounds to electronic signals, and is operatively connected to the electronic processor. One or more secondary audio signal sources operatively connects to the electronic processor. A common audio output is connected to electronic processor to convert electronic stethoscope signals or secondary audio signals to acoustic output. These sounds may be produced separately or mixed.

Claims

1. An electronic stethoscope with expanded program execution and communications capability, comprising:

a portable housing in the physical form of a stethoscope that is wearable around the neck or shoulders of an operator, to house further elements comprising;

central processing unit;

nonvolatile digital memory means selected from a group consisting of flash memory, electrically erasable programmable read only memory (EEPROM), and magnetic media;

one or more software programs, executable by said central processing unit, which expand the functions executed by said stethoscope,

said functions comprising medical measurement, information processing and communications functions;

digital communications means;

wherein said software programs are transferred via said digital communications means, stored in said nonvolatile digital memory means, and executed by said central processing unit.

2. The electronic stethoscope as in claim 1 wherein said digital memory means is physically removable from electronic stethoscope housing.

3. The electronic stroboscope as in claim 1 wherein said digital communication means is a wired cable.

4. The electronic stethoscope as in claim 1 wherein said digital communications means is an infrared optical communications link.

5. The electronic stethoscope as in claim 1 wherein said digital communications means is a wireless communications link.

6. The electronic stethoscope as in claim 1 wherein said digital communications means is a wireless communications means physically removable from said electronic stethoscope housing.

7. The electronic stethoscope as in claim 1 wherein said digital communications means uses an 802.11 communications protocol.

8. The electronic stethoscope as in claim 1 wherein said digital communications means uses an Internet protocol selected from the group consisting of transmission control protocol/Internet protocol (TCP/IP), file transfer protocol (FTP), and point to point protocol (PPP) communications protocols.

9. The electronic stethoscope as in claim 1 wherein said one or more software programs are medical information software programs selected from the group consisting of drug dosage database access software, drug interaction database access software, and medical research database access software.

10. The electronic stethoscope as in claim 9 further comprising a barcode reader operatively connected to said central processing unit such that database reading and writing can be effected by barcode scanner input.

11. The electronic stethoscope as in claim 1 wherein said software includes algorithms for the processing of auscultation sounds.
