Abstract
Abstract A throwaway, one-time use signal sensing and telemetric transmitting device for use such as in the care of medical patients requiring a monitoring of a physiological function such as the cardiac function of the patient. The device includes one-time use self-powering battery means, adhesive means for attachment of the device to the patient and electrodes for sensing the physiological functioning. A disposable cover is removed to expose the adhesive means and the battery means are actuated to power the device at the time of use. The radio frequency transmitted signal is received on a suitable radio telemetry receiver for monitoring and recording as desired.

Claims Analysis
Total Claims: 21
Claim 1
Independent Claim
152 words
A throwaway, one-time use physiological signal sensing and telemetric transmitting device comprising: a mounting element; electrodes carried by said mounting element; adhesive means carried by said mounting element for causing a substantially one-time adherence of the mounting element to the skin of a patent with the electrodes in electrical-signal-receiving contact with said patient; a wireless transmitter carried by said mounting element connected to said electrodes for transmitting a signal corresponding to physiological information picked up by said electrodes; battery means carried by said mounting element for self-powered operating of said device; and means carried by the device for maintaining the device inoperative prior to a desired use and irreversibly manually operable to cause the transmitter to be placed in a one-time energized operative condition, the elements of the device being miniaturized to provide a low cost construction suitable economically to permit disposal of the device upon completion of a one-time use thereof.
Claim 2
Dependent Claim
152 words
A throwaway, one-time use physiological signal sensing and telemetric transmitting device comprising: a mounting element; electrodes carried by said mounting element; adhesive means carried by said mounting element for causing a substantially one-time adherence of the mounting element to the skin of a patent with the electrodes in electrical-signal-receiving contact with said patient; a wireless transmitter carried by said mounting element connected to said electrodes for transmitting a signal corresponding to physiological information picked up by said electrodes; battery means carried by said mounting element for self-powered operating of said device; and means carried by the device for maintaining the device inoperative prior to a desired use and irreversibly manually operable to cause the transmitter to be placed in a one-time energized operative condition, the elements of the device being miniaturized to provide a low cost construction suitable economically to permit disposal of the device upon completion of a one-time use thereof.
Claim 3
Dependent Claim
21 words
