Vital signs monitoring system
First Claim
1. A portable patient vital signs monitoring system comprising, in combination:
- first sensing means to be attached to a patient'"'"'s body for sensing a first physiological condition represented by heart and lung sounds and for generating a first electrical signal corresponding thereto;
second sensing means to be attached to a patient'"'"'s body for sensing a second physiological condition and for generating a second electrical signal corresponding thereto;
elongated conductor means connected to said first and second sensing means for conducting said signals away from the patient'"'"'s body;
a remotely located monitoring unit including control means connected to said conductor means for receiving said first and second signals from said conductor means and for processing said signals;
said monitoring unit including an IR transmitter having emitter means for omnidirectional transmission of said processed first and second signals; and
a remote portable, IR receiver to be worn on an operator'"'"'s body for receiving said processed first and second signals and for converting said received signals into audible form.

Abstract
A vital signal monitoring system for monitoring the vital signs of a patient, particulary prior to and during anesthesiology, during and after operational procedures, includes first sensor unit including a microphone for mounting on the patient'"'"'s chest for picking up breath and heart sounds with a filter and automatic gain control circuit, second sensor unit including a microphone for positioning beneath the blood pressure cuff for picking up the blood flow sounds with a filter and automatic gain control circuit, both connected into a system of electronic components with selection means for selecting either of these sound systems and transmitting the sounds by way of an audio IR transmitter to a portable audio IR receiver carried by a monitoring physician, including an earphone for monitoring the selected sounds. Each sensor unit also includes a thermistor for measuring the patient'"'"'s external temperature. This system is combined into a patient monitoring system including an esophageal stethoscope for monitoring a patient'"'"'s vital signs during surgery with the system including electronics processing circuitry and a microprocessor unit programmed to initiate test procedures, control multiple vital signs displays and for initiating one or more alarms in response to deviation from normal vital signs conditions. The overall system includes a switch selector bank permitting the monitoring physician to select one of the three sensing systems to monitor with the portable receiver enabling the attending physician to move freely about an operating room during the monitoring procedures.
