Electronic stethoscope having battery carriage
First Claim
1. An electronic stethoscope adapted to receive auscultatory sounds from a body, adapted to transmit, said auscultatory sounds to a user, and adapted to be powered by a battery having a positive terminal and a negative terminal, comprising:
- a chestpiece adapted to be utilized in cooperation with said body;
an acoustical transducer cooperating with said chestpiece for receiving said auscultatory sounds and transforming said auscultatory sounds into an electrical input signal;
signal processing means being operatively coupled to said acoustical transducer for processing said electrical input signal to produce an electrical output signal;
speaker means operatively coupled to said signal processing means for converting said electrical output signal into an acoustical output signal;
an earpiece receiving said acoustical output signal and providing said acoustical output signal to, said user;
said chestpiece having a cavity adapted to contain said battery;
power supply means for supplying electrical power from said battery to said signal processing means, said power supply means having a positive electrical connection and a negative electrical electrical connection; and
a battery carriage being slidably insertable into said cavity of said chestpiece and adapted to receive said battery before said battery carriage is inserted into said cavity of said chestpiece, said battery carriage providing electrical continuity from said battery to said power supply means when said battery carriage is inserted into said cavity of said chestpiece, said battery carriage receiving said battery in only one orientation with said positive terminal of said battery being electrically coupled to said positive electrical connection;
said battery carriage receiving said battery so that said positive terminal of said battery can only be electrically coupled to said positive electrical connection of said power supply means;
wherein said battery carriage provides a wiping action for said positive electrical connection upon said insertion of said battery carriage into said chestpiece.

Abstract
An electronic stethoscope which is adapted to receive auscultatory sounds from a body, is adapted to transmit the auscultatory sounds to a user, or other medical device which is adapted to be powered by a battery. The stethoscope has a chestpiece adapted to utilized in cooperation with the body, an acoustical transducer cooperating with the chestpiece for receiving the auscultatory sounds and transforming the auscultatory sounds into an electrical input signal. The stethoscope or medical device has an electronic processor for processing the electrical signal. The stethoscope has a speaker for converting the electrical output signal into an acoustical output signal and an earpiece receiving the acoustical output signal and providing the acoustical output signal to the user. The chestpiece (or housing of the medical device) has a cavity adapted to contain the battery. A battery carriage is insertable into the cavity of the chestpiece and is adapted to receive the battery before the battery carriage is inserted into the cavity of the chestpiece or housing. The battery carriage provides electrical continuity from the positive terminal of the battery to power supply circuitry when the battery carriage is inserted into the cavity of the chestpiece or housing. The battery carriage receives the battery in only one orientation with the positive terminal of the battery coupled to the positive electrical connection.
