Abstract: A sensor patch for attachment to a patient's body for obtaining physiological data from the patient and transmitting the physiological data to monitoring equipment. The sensor patch includes a structural support for supporting the sensor patch on the patient's body, a sensor for sensing physiological data from the patient's body, an adhesive for attaching the sensor patch to the patient's body, an electronics package including a power supply and circuitry for processing the sensed data to produce a conditioned signal, communications equipment for passing the sensed data from the sensor to the electronics package, and a transmitter for transmitting the conditioned signal from the sensor patch to the monitoring equipment. In a preferred embodiment, the electronics package and transmitter form part or parts of the sensor patch itself, and the sensor comprises one or more thermistors to sense the temperature of the patient's body. In another embodiment, the transmitter is an infra-red transmitter.

Abstract: A portable combined pacemaker parameter and vital sign monitor acquires data relating to a patient's ECG waveform and an in vivo pacemaker waveform by means of electrodes which contact the patients's skin near the location of the patient's pacemaker. The monitor detects signals from the pacemaker and displays derived waveforms on a self-contained display screen. The monitor also includes a storage device to store data derived from the detected signals for subsequent recall and analysis. The waveform information is displayed on the monitor so as to show the relationship in time between the ECG waveform and the pacemaker waveform. The monitor is particularly useful for the portable measurement of ECG and/or pacemaker waveforms and for the ongoing analysis of the condition of a working pacemaker in vivo.
