Abstract

A lightweight, improved precordial suction stethescope constant monitoring system including a heart and breath sound detection means, solely mounted to patient using only suction or other connection means, and an inexpensive radio wave transmission means and a remote radio wave receiver and audio means. A quick connect suction cup or other stethescope, which is especially suitable for use on the wet skin of a newborn, is used to provide the acoustical recess of the stethescope head. A microphone transducer located in the stethescope head or in a detachable housing is used for converting acoustical vibrations into an electrical impulse. The said remote radio wave receiving means amplifies and converts the electronically transmitted physiological condition information into an audible signal. This system allows the attending medical personnel to be totally free of any physical connection to the patient being monitored.
