Claim 1
Independent Claim
211 words
An improved stethoscope comprising: a. a chest piece having a body containing: 1. a pick up section; 2. an amplifier section; and 3. a display section; in which the pick up section comprises a diaphragm or bell mounted on the body and adapted to pick up the vibration of heart or other bodily sounds and a transmission space containing a vibration transmitting medium and means to pick up the vibration of heart sounds and convert them to an electrical signal and transmit them to the amplifier section; and in which the amplifier section is spaced from the diaphragm or bell and comprises miniaturized circuitry adapted to receive the transmissions from the pick up section, amplify and transmit signals to the display section; and in which the display section comprises a miniaturized cathode ray tube for receiving and displaying a signal from the amplifier section, the display section being located on the stethoscope proximate to the body; b. a tube assembly comprising a hollow tube communicating with the transmission space and dividing to form a pair of tubes adapted to reach the ears of the stethoscope user and to transmit the vibration of heart or other bodily sounds. c. an integral power source for operating the amplifier and the cathode ray tube.
