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.
