[Postoperative hydrocephalus. Automatic control of intracranial pressure in patients treated with external drainage].
An experimental analogical device is described; it is able to stabilize the intracranial pressure (ICP) at an adjustable value in subjects exhibiting hydrocephalus. The mean ICP is measured by the intraventricular catheter, using a pressure measurement apparatus of conventional electric design. The result and two practical examples are presented.
