ABSTRACT:
A telemetering intracranial pressure transducer comprises an airtight casing member housing a pressure-electric transducer for detecting an intracranial pressure, a pressure-receiving layer disposed in contact with the pressure-electric transducer and in pressed engagement with the dura under the skull, and a transmitting circuit for transmitting an output signal indicative of the intracranial pressure through a transmitting antenna. The transmitting circuit includes a telemetering transmission circuit, a microbattery and a switch for switching on and off the microbattery. The transducer thus constructed is entirely embedded below the head, dispensing with external wires or a receiving coil on the head, and detects an intracranial pressure safely and accurately without confining or disturbing the activities of a testee.
