Kind Code:
A3
Abstract:
The application relates to a hydrocephalus valve (100) for draining fluid from the ventricle systems of patients, said valve having at least one housing (200) with a housing interior (201); and at least one first passage for admission (202) and/or discharge (203), and having at least one body (500) provided in the housing interior, said body being designed to move in at least one direction. At least one adjusting unit (700) is provided. The application aims to improve tried-and-tested existing valves. To achieve this, the adjusting unit is designed to adjust at least one drainage rate in the passage, and to allow the drainage rate to be adjusted between 1 ml per hour and 1000 ml per hour at a pressure at the hydrocephalus valve of 20 cm water column, in order to slow or accelerate, by means of this adjustment, a change in pressure in the ventricle system that results from the drainage.
