First Claim
Patent Images
1. A medical monitoring device for monitoring the pulse and respiration rate of an individual, said device comprising:
- a bladder member having means conditioned for placement against and contact with the body of said individuals, said bladder member including attached acoustic sensor means for detection o the heartbeat sounds of said individual, and delivery of a pulse signal when such heartbeat sounds are detected, said bladder member further including attached pressure sensor means for detection of the bodily expansion during respiration by the indivdual, and delivery of a respiration signal when such bodily expansion is detected;
signal processing means for receiving said pulse signal delivered by said acoustic sensor and said respiration signal delivered by said pressure sensor, said signal processing means conditioned to time the repetitive receipt of each of said pulse signal and said respiration signal, said signal processing means further conditioned to deliver an alarm signal when either of said pulse signal or said respiration signal is not received within a predetermined time;
speaker means for generation of an audible alarm upon receipt of said alarm signal from said signal processing means;
transmitter means for transmission of a radio alarms signal upon receipt of said alarm from said signal processing means; and
remote alarm means for receipt of said radio alarm signal from said transmitter means, and generation of a remote audible alarm upon such receipt.

Abstract
A medical monitoring device monitors the pulse and respiration rate of an infant, and transmits an alarm signal to a remote receiver when pulse and/or respiration rate irregularities are detected. The device incorporates an acoustic sensor (microphone) and pressure sensor adjacent a small gas or liquid-filled bag or bladder member. The bladder member and attached sensors are contained in a compact monitor housing which is positioned against the monitored infant'"'"'s body, so that the bladder member directly contacts the body, and is preferably held in place by a small belt wrapped around the infant.
