Patient monitoring system
First Claim
1. A system for monitoring physiological variables of a patient and evaluating the patient'"'"'s condition from the information contained therein comprising:
- a sensor for transducing select physiological variables used to detect the onset of a select physical malady in said patient and producing analog signals in accordance therewith;
circuitry for processing said analog signals and converting same to digital signals;
a signal analysis computer in proximity with said patient, said signal analysis computer is used for analyzing said digital signals by comparing same with reference signals corresponding to the same physiological variable and said signal analysis computer is used to detect the onset of said select physical malady in said patient and producing first code signals in accordance with the comparison;
a decision computer for processing the first code signals produced by the signal analysis computer, evaluating same to determine if the onset of a physical malady will affect the patient'"'"'s condition requiring medical treatment, and generating coded control signals indicative of the condition if such determination is made; and
a short wave transmitter for receiving said coded control signals and short wave transmitting said coded signals to a monitor station wherein medical personnel will be alerted as to the onset of said select physical malady by an alarm.

Abstract
A system for monitoring and computer analyzing select physiological variables of a patient in real time in order to alert medical personnel to the need for medical treatment or automatically administering such treatment under computer control. Such physiological variables monitored by the system may include lung sounds, respiratory rate and rhythm, heart rate and rhythm, heart sounds, and body temperature. Coded signals relating to the physiological variables are produced and compared with reference versions of same by a decision computer in order to evaluate the patient'"'"'s condition. If the evaluation indicates medical treatment is needed, the decision computer activates a local and/or a remote alarm to alert medical personnel and/or activates one or more actuators for adminstering a medical treatment such as the injection or infusion of a drug.

13. A system for monitoring the condition of a patient comprising:
-
a body sound sensor for transducing respiratory and heart sounds and producing audio signals in accordance therewith; electronic circuitry for processing said audio signals and generating digital signals therefrom; a signal analysis computer for analyzing said digital signals by electronically comparing said signals with reference signals corresponding to respiratory and heart sounds and producing code signals in accordance with the comparison; a monitor station remote from said patient; a decision computer for processing the code signals produced by the signal analysis computer, determining if the patient'"'"'s condition requires medical treatment, and generating coded control signals indicative of the determination; and a short wave transmitter for transmitting said coded control signals to said monitor station wherein an alarm indicates that the patient'"'"'s condition requires medical treatment. - View Dependent Claims (14, 15, 16)
