Cerebrospinal fluid stop valve

Abstract

The invention discloses a cerebrospinal fluid stop valve. The erebrospinal fluid stop valve comprises a polysulfone plastic connector. The polysulfone plastic connector is axially provided with a first through hole. A groove communicated with the first through hole is formed in the polysulfone plastic connector. A silica gel membrane covers the orifice of the first through hole and is provided with a second through hole. The silica gel membrane is provided with a polysulfone plastic pressing cap matched with the polysulfone plastic connector. The polysulfone plastic pressing cap is provided with a third through hole. The first through hole, the second through hole and the third through hole are communicated with one another. The inner diameters of the first through hole and the third through hole are larger than the outer diameter of a catheter. The inner diameter of the second through hole is smaller than the outer diameter of the catheter. The cerebrospinal fluid stop valve has the advantages that the stop valve can effectively prevent cerebrospinal fluid from flowing out of a human body through the gap between a needle seat and the catheter during surgery, the surgery can be performed smoothly, the health of a patient is guaranteed, and the embarrassment of helplessness of doctors when the cerebrospinal fluid flows out of the human body during the surgery can be prevented effectively.

AI Technical Summary

Benefits of technology

This technology prevents blood or other fluids from coming back into your brain's spine by creating tiny gaps where there are two parts - one on top of another called an insertion point for inserting medical instruments like syringe needles with small holes inside it.

Problems solved by technology

This patented technology solves issues with controlling the amount of liquid that flows from brain tissue during medical procedures without causing any harm or discomfort for patient's own safety.
