摘要：
A pressure valve for regulating intracranial pressure by means of draining cerebrospinal fluid and a method for using same, the pressure valve comprising: a valve housing (100)； a partitioning member (200), the partitioning member (200) being movably disposed in the valve housing (100) and partitioning an inner cavity of the valve housing (100) into a liquid-containing chamber (110) and a liquid-free chamber (120)； the liquid-containing cavity (110) comprises: a liquid outlet channel (111), the liquid outlet channel (111) being located in the liquid-containing chamber (110) and being in contact with the partitioning member (200) under a normal state, wherein the partitioning member (200) may control the opening or closing of the liquid outlet channel (111)； a liquid storage chamber (112), the liquid storage chamber (112) being used for storing a liquid； when the liquid outlet channel (111) is opened, the liquid in the liquid storage chamber (112) may flow into the liquid outlet channel (111)； an adjusting mechanism (300), the adjusting mechanism (300) being disposed in the liquid-free chamber (120) and comprising: a force applying member (310), the force applying member (310) being used for applying a pushing force to the partitioning member (200) for closing the liquid outlet channel (111)； an adjusting member (320), the adjusting member (320) being used for adjusting the magnitude of the pushing force applied by the force applying member (310).L'invention concerne une soupape de pression permettant de réguler la pression intracrânienne au moyen du drainage d'un liquide céphalo-rachidien et son procédé d'utilisation, la soupape de pression comprenant : un boîtier (100) de soupape ； un élément de séparation (200), l'élément de séparation (200) étant disposé mobile dans le boîtier (100) de soupape et divisant une cavité interne du boîtier (100) de soupape en une chambre (110) contenant le liquide et une chambre (120) exempte de liquide ； la cavité (110) contenant du
