ELECTRONIC SYSTEM FOR MESURING THE RATE OF HEART BEAT FOR MEDICAL MONITORING AND REMOTE WARNING BY RADIOFREQUENCY LINK

摘要

The system provides for the remote and permanent monitoring by radiofrequency with alarm of an infant, a child or an adult. A miniature sensor-emitter, attached to the wrist of the patient, comprises a sensor (1) which detects the beats of the pulse, a circuit (2) intended to shape and code the information concerning the "rate of heart beat" and "presence of cardiac pauses", if any, and an emitter (3) sends the radiofrequency signal S. A receiver-display unit provides for the remote monitoring of the patient and comprises a radiofrequency receiver (7) intended to pick up the signal S, a circuit (8) providing for the decoding of the signal S, and the display of the rate of heart beat R by means of a digital display (9). The circuit (8) further compares permanently R with minimum and maximum values, and sets off alarms (10, 11 and 21) if said extreme values are exceeded, or if cardiac pauses are detected.
