ABSTRACT:
An apparatus and method are provided for detecting body vibrations of a living animal or human being, such as those generated by heart function and respiration. The system employs a rigid spring-like structure formed of one or more deflectable elements such as metal or plastic strips or a strip-like formation, preferably configured in a sinuous or irregular path and supported at one or more locations along its length by a support, such as a frame forming the wall of a container such as the bottom of a bassinet or other container. In one form, the irregularly shaped deflectable member or members are disposed to be directly engaged by an animal lying thereon, for testing purposes. In another form, a sheet of plastic is disposed across the deflectable member or members on the upper surface of which a portion of the body of an animal or human being may lie or sit to permit body vibrations to be transmitted through the sheet to the deflectable member and to be detected when such member deflects. The vibrational energy transmitted to the deflectable member is conducted therefrom through a centrally disposed rod or pin to a transducer, such as an audio speaker, which transduces the vibrational energy to electrical signals which may be amplified and detected by a recording or indicating instrument.
