Description
Technical field
The invention belongs to medicine equipment, after neurosurgery ventriculo-peritoneal shunt, regulate and control brain ridge according to intracranial pressure particularly to one
Liquid shunt volume also can prevent the device that isocon blocks.
Background technology
Ventriculo-peritoneal shunt operation is the hydrocephalic conventional operation of neurosurgical treatment.Ventriculo-peritoneal shunt Post operation, by
Inserting an isocon between the ventricles of the brain and abdominal cavity, cerebrospinal fluid shunt unnecessary in the ventricles of the brain enters abdominal cavity can reduction of patient intracranial hypertension
Symptom, but the Hypotensive cranial pressure that shunting excessively causes is likely to cause patient fatal threat.In branching process, shunt pipe plug
