Device for draining cerebrospinal fluid

摘要: A device for draining cerebrospinal fluid automatically to the venous system in cases of hydrocephalus. The includes an outer elastic tube which houses its interior identically flow oriented upstream and downstream check (unidirectional) valves respectively communicating with system. Each valve inner tubular member within having open end a closed end. At region each is formed at least one axially extending slit forms outlet valve. Within freely movable ball located where situated. rigid situated has short distance from provide restricted extent free movement. Because movability this thereof kept clean, particularly slits, thus malfunctioning due clot formations reliably avoided. Moreover, since extends substantially member, dead space blood can obstruct eliminated danger infection reduced.
