摘要

(57) Abstract For example the patient who possesses the normal cranial internal pressure (the patient who is not ill the hydrocephalus), relative at fixed flux of for the sake of, the cerebrospinal fluid of the patient (CSF) the device and method in order to remove CSF from the cavity. For example as for these devices and method, the normal cranial internal pressure (, -170mmH2O in the patient who is upright the cranial internal pressure with 200mmH2O in the patient who has lain) being similar, relatively low flux (usually, under 0.2ml/minute) with it offers the discharge road which makes the removal of CSF possible. The removal of CSF at relatively low one constant speed is suitable, although virulence in Alzheimer''s disease, and CSF and/or it remedies the other condition which it is related to the existence of the pathogenic substance, especially.
