Pressure gauge, particularly for measuring intracranial pressure

Abstract

Abstract The pressure sensor is comprised of a cylindrical cavity (21) of which the front face has the form of a membrane (23), and is also comprised of an oscillator (29). The signal frequency of the oscillator provides a measuring value of the pressure exerted on the membrane; said signal (32) is radio-transmitted and may be processed by means of an appropriate receiver provided with a frequency counter or similar. The power supply is provided by means of an incorporated battery (31) or by irradiation. In order to measure the intracranial pressure, the pressure sensor is implanted in the cranial bone (11) by means of a special coupling sleeve (18).
