发明名称 Brain ventricle shunt system
摘要 A brain ventricle shunt system having a first catheter to be inserted into brain ventricle, a second catheter to be inserted into another part of a human body, and a shunt main body connected at one end thereof to the first catheter and at the other end to the second catheter. A check valve is provided for preventing cerebrospinal fluid from flowing back from the second catheter to the first catheter. The shunt main body has a reservoir formed therein and communicated with the first catheter to store the cerebrospinal fluid therein. A dome-shaped flexible portion is formed on the shunt main body and defining the reservoir. The dome-shaped flexible portion is provided to be upwardly projected from the shunt main body by pressure of brain ventricle and provided to be pressed through a scalp by a rod of an external pressure sensor to compress the reservoir.
