ABSTRACT:
A differential pressure sensing device is fully implanted beneath the skin in the living body such that its pressure responsive means, such as a diaphragm means, senses the difference in pressure between an internal bodily pressure and the pressure on the skin which is just above the sensor. The sensor has a stop, or a mechanical contact means, for the diaphragm means so that the diaphragm will be pressed against the stop when an externally applied pressure on the skin equals or exceeds the internal pressure. The sensor also has a means with a detectable parameter that can be detected outside the body by external apparatus. The external apparatus also converts the parameter to an audible sound or audio signal. The parameter has a specific response when the diaphragm is near the stop position, and this response can be heard via the audio signal. Thus by increasing the externally applied pressure to the skin above the sensor and listening for the characteristic audio signal corresponding to the diaphragm being at or near the stop position, one can determine the external pressure needed to balance the internal bodily pressure, and thus measure the latter.
