Abstract
A sensor system for measuring the blood pressure in such a way that the sensing position is in a correct position relative to the heart is devised. The system consists of a wireless sensing device, a transceiver, and a computing and recording device. The sensor reading is recorded wirelessly. The sensor is placed at a convenient location on the body. The coupling antennas are designed in such a way that the antenna characteristics ensures that only when the sensors is within a predetermined position relative to the heart will a recording of the blood pressure actually take place.
Claims9
A system for measuring blood pressure in an artery by wireless reading of a sensor comprising:
- a sensor having a sensor antenna, the sensor being mounted in close proximity to an artery and emitting a sensor signal in response to the blood pressure in the artery, and wherein the sensor antenna allows for wireless reading of the sensor signal, and
- a transceiver having a transceiver antenna and being adapted to wirelessly read the sensor signal from a position close to the heart of the patient,
- wherein antenna properties of the sensor antenna and the transceiver antenna are designed so that a reading of the sensor signal can only be performed when the sensor is within a predetermined space relative to the transceiver.
