ABSTRACT:
A self-contained stethoscope transmitter comprises a pickup head including a housing which defines a precordial dome formed thereinto for contact with a patient whose bodily sounds are to be observed and/or monitored, and electronic circuitry positioned within the housing for receiving the sounds, converting the sounds into an FM signal representative thereof and transmitting the FM signal. The frequency of transmission is tunable over a range of frequencies by using a screwdriver which is removably secured within the housing. The pickup head includes a luer taper within a base of the head for alternate operation with an esophageal probe. The base can also be rotated relative to the remainder of the head to configure the head for either precordial or esophageal use with rotation of the head switching an internal battery to conserve the battery for shipment, storage or extended usage of the transmitter if desired. Preferably, the pickup head is constructed of inexpensive materials such that the stethoscope transmitter can be thrown away after a single use without concern for contamination which would otherwise require cleaning and sterilization of the stethoscope transmitter for subsequent use.
