Description (Brief)
Rectangular and gray plastic, marked "CardioBeeper Heart Monitor." Three buttons are located on the front of the monitor, respectively marked "Test," "Beep," and "ECG." On the upper right side of the CardioBeeper is a red light recessed into a red triangle, and just below is a green light recessed into a green square. Two black electrodes with wires are stored in the back of the device. One black wire is marked "left," and the white wire is marked "right." The beeper is stored in a zippered brown plastic case with black trim. The case is marked "Survival Technology Inc: Bethesda MD."
The CardioBeeper was Invented by Stanley J. Sarnoff, M.D. (1917-1990). His most recognized invention is the Epi-Pen. Sarnoff founded the Rodana Research Corporation and its successor Survival Technology Inc. is a subsidiary of Meridian Technologies, which itself is a subsidiary of Pfizer. The original request to patent the CardioBeeper was filed in 1973 and the patent was issued in 1976. CardioBeeper received FDA approval in 1981. CardioBeeper was produced and manufactured during the 1980s, and was used by patients to monitor their heart rate. As a battery powered, hand held device, the CardioBeeper could be used by patients to monitor their heart rate and transmit their data via the telephone to their doctor. The two electrodes are placed under the armpits of the patient, and the physician and patient stay in contact as the data is transmitted by telephone.
