ABSTRACT:
System for measuring or monitoring the intracranial pressure which comprises a non-elastic detecting pouch to be inserted into the space between the skull and the cerebrum, a flexible tube connected to the pouch, a device for supplying a liquid into the pouch through the flexible tube and a device for measuring the pressure of the liquid in the pouch. When the pressure of the liquid reaches the intracranial pressure, the curve showing relation between liquid pressure vs. pouch volume flattens. Thus, by measuring the pressure of the flattened region, intracranial pressure may be determined.
