A design of brain port with a built-in bi-directional check valve improves the ventriculostomy

초록

The increase of intracranial pressure is a life-threatening condition which requires urgent treatment to prevent the further neurologic problem. A design of the brain port is proposed, in which a bi-directional check valve controls the flow of the cerebrospinal fluid depending on the intracranial pressure in accordance with the other devices. Drug administration and cerebrospinal fluid drainage could be performed easily without any additional surgery other than the transplant of a brain port. The intracranial pressure value at which the cerebrospinal fluid should be drained is adjustable by altering the pressure of the drainage bag. The results of the experiment with the simulated brain system are supporting and verifying the substance of this article.
