A kind of anti-siphon means of hydrocephalus drainage tube,Include: a ventricular drainage tube,One peritoneal cavity drainage tube,One one-way control valve and an anti-siphon means； Wherein the anti-siphon means set a guide wire,The guide wire set the what one-way control valve,Between the peritoneal cavity drainage tube,The guide wire sets an inflow pipe,Guan Yuyi loop pipe is flowed into communicate,The loop pipe is communicated with siphunculus in two,This in two siphunculus communicated with an effuser； Also,Set that a upper cover covers body and a lower cover covers body on the guide wire,On this,Lower cover cover body it is just upper,Lower cover covers the guiding pipe surface and oppress on what loop pipe,Lower section,Use the flow velocity that compressing mode slows down celiolymph； In this way,Through on this,The compressing that lower cover covers body slows down flow velocity,It prevents from generating larger siphonage in the what hydrocephalus drainage tube due to sufferer sits up or stands,It avoids excessively aspirating hydrocephalus.一種腦積水引流管之抗虹吸裝置，包括：一腦室引流管、一腹腔引流管、一單向控制閥及一抗虹吸裝置；其中該抗虹吸裝置設一導引管，該導引管設於該單向控制閥、該腹腔引流管之間，該導引管設一流入管，流入管與一環狀管相通，該環狀管與二中通管相通，該二中通管與一流出管相通；又，該導引管上設一上蓋覆體及一下蓋覆體，該上、下蓋覆體恰上、下蓋覆該導引管表面並壓迫於環狀管上、下方，藉以壓迫方式減緩腦脊髓液之流速；如此，透過該上、下蓋覆體之壓迫減緩流速，即防止因該病患坐起或站起而於該腦積水引流管中產生較大虹吸作用，避免過度抽吸腦積水。
