ABSTRACT:
This invention provides a method for measuring intracranial pressure and a device for the same which enable intracranial pressure to be accurately measured without any conventional calibration using data obtained by previous measurement because they are characterized in that intracranial pressure is measured after a communication valve capable of communicating with the atmosphere is closed following zero point correction of a pressure transducer performed by adjusting the internal pressure of a flexible membrane provided at the tip of a pressing part and filled with a fluid to atmospheric pressure by the operation of the above communication valve.
