Attorney, Agent or FirmInternational ClassA61B 005/02AbstractA 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. | |
