High sensitivity stethoscopic system and method
First Claim
1. A constant monitoring stethoscope and radio wave transmitter and receiver system connectable to a local radio receiver only by radio waves for amplifying stethoscopically monitored heart and chest sounds to attending personnel that are not directly connected to the patient or said stethoscope and transmitter system, said constant monitoring stethoscope and radio wave transmitter and receiver system comprising:
- a stethoscope head defining an acoustic contactor body means having a closable opening formed therein including an acoustic pickup recess means for capturing acoustical vibrations between the skin of the patient and the acoustic contactor body means,a microphone transducer means sealably connected directly into said opening formed in said connector body to enclose and seal said contactor body and define a sealed acoustic pickup recess means for converting acoustical vibrations in said recess to electrical signals;
a radio transmitter means having an input means, said input means connected to said transducer microphone, said input means of said radio transmitter means for receiving said electrical signals, said radio transmitter means including amplifier means connected to said input means for amplifying said electrical signals, and an antenna means connected to said radio transmitter means to transmit radio waves of said acoustical sounds,said contactor body means connecting said constant monitoring stethoscope and radio wave transmitter system to a patient, said contactor body means formed from a flexible material and shaped as an inverted concave member forming in said recess a partial vacuum acoustical space between the patient'"'"'s skin and said recess means wherein acoustic vibrations permeating from the patient'"'"'s inner organs are transferred without distortion or being diminished through said partial vacuum in said acoustical space to said sealably connected microphone transducer means and then transmitted to the local radio receiver.

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.

-
a stethoscope head defining an acoustic contactor body means having a closable opening formed therein including an acoustic pickup recess means for capturing acoustical vibrations between the skin of the patient and the acoustic contactor body means, a microphone transducer means sealably connected directly into said opening formed in said connector body to enclose and seal said contactor body and define a sealed acoustic pickup recess means for converting acoustical vibrations in said recess to electrical signals; a radio transmitter means having an input means, said input means connected to said transducer microphone, said input means of said radio transmitter means for receiving said electrical signals, said radio transmitter means including amplifier means connected to said input means for amplifying said electrical signals, and an antenna means connected to said radio transmitter means to transmit radio waves of said acoustical sounds, said contactor body means connecting said constant monitoring stethoscope and radio wave transmitter system to a patient, said contactor body means formed from a flexible material and shaped as an inverted concave member forming in said recess a partial vacuum acoustical space between the patient'"'"'s skin and said recess means wherein acoustic vibrations permeating from the patient'"'"'s inner organs are transferred without distortion or being diminished through said partial vacuum in said acoustical space to said sealably connected microphone transducer means and then transmitted to the local radio receiver. - View Dependent Claims (2, 3, 4, 5)

6. A process for utilizing a stethoscope constant monitoring system including a stethoscope head defining an acoustic contactor body means having a closable opening formed therein including an acoustic pickup recess means for capturing acoustical vibrations between the skin of the patient and the acoustical contactor body means, a microphone transducer means sealably connected directly into the said opening formed in said connector body to enclose and seal said contactor body and define a sealed acoustic pickup recess means for converting acoustical vibrations in said recess to electrical signals, said contactor body means formed from a flexible material and shaped as an inverted concabe member which when squeezed by fingertip pressure of the attending personnel forming in said recess a partial vacuum acoustical space between the patient'"'"'s skin and said recess means wherein acoustic vibrations permeating from the patient'"'"'s inner organs are transferred without distortion or being diminished through said partial vacuum in said acoustical space to said sealably connected microphone transducer means comprising the steps of:
-
(a) selecting the desired location on a patient to be monitored by said stethoscope constant monitoring system, (b) arranging said suction stethoscope head upon said area, (c) applying the necessary pressure upon said suction stethoscope head so as to cause the body of said suction stethoscope head to yield inwardly toward the patient'"'"'s body thereby forcing a volume of air within the acoustical recess to emerge from said recess passing through the area of contact between said patient'"'"'s body and said suction stethoscope head; and (d) disengaging all pressure and fully removing the pressure (hand) source from said suction stethoscope head thereby causing a partial outward displacement of the inwardly displaced portion of said suction stethoscope head which will result in a state of negative pressure relative to ambient pressure within the acoustic recess of said suction stethoscope head and causing said suction stethoscope head to come into firm contact with said patient, said pressure differential resulting in the continuous equilibrium fixed position of said suction stethoscope head.

7. A process for utilizing a stethoscope constant monitoring system including a solely patient mounted heart and breath sound detection means comprising a cup with an acoustical recess designed and arranged to remain connected in any desired location on a patient for monitoring acoustical vibrations therefrom and a detachable microphone transducer means sealably yet removably connectable to the cup, comprising the steps of:
-
(a) selecting the desired location on a plurality of patients to be monitored by said stethoscope constant monitoring system, (b) providing a plurality of said cups; (c) arranging each of said cups upon said locations; (d) securing said plurality of said cups to the bodies of the patients; and (e) engaging said microphone transducer means in a first of said plurality of said cups to monitor heart and breath sounds; (f) quickly disengaging said microphone transducer means from said first cup and reconnecting it to another different cup of said plurality of said cups.
