title: [One-way valve extension tube for continuous cerebrospinal fluid drainage system].
abstract: We designed an extension tube with built-in one-way valve to be used in the external CSF drainage. Placement, replacement or removal of the value can be performed easily and rapidly in patients who require continuous external CSF drainage. Advantages of the system using this one-way value extension tube were discussed. History of ventricular drainage was also mentioned.
