Cerebrospinal fluid drainage system and adjusting device in same

Abstract

An embodiment of the invention provides a cerebrospinal fluid drainage system and an adjusting device in the same. The device comprises an upper cover, a base, a flow limiting seat, an anti-siphon ball, a supporting piece and a spring plate. The upper cover and the base are combined to form a hollow structure, the flow limiting seat is fixed in the hollow structure, and a sealing cavity is formed in the flow limiting seat; the anti-siphon ball is positioned in the sealing cavity, is placed in a ball mounting hole, and is used for blocking the ball mounting hole; the supporting piece is positioned in the sealing cavity and is mounted in a supporting piece mounting hole; a supporting table is arranged at the top end of the supporting piece; the spring plate is positioned in the sealing cavity; a first end of the spring plate is in lap joint to the anti-siphon ball; a second end of the spring plate is in lap joint to the supporting table; a mounting part is arranged in the middle of the spring plate; and a spring plate support limits the spring plate through the mounting part. By the scheme, the problems of control and regulation on pressure and drainage speed in a cerebrospinal fluid drainage process, counterflow and excessive drainage due to rapid change of intracranial pressure are solved, and meanwhile, nursing operation in a drainage process is facilitated.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an adjustment device in a cerebrospinal fluid drainage system and the cerebrospinal fluid drainage system. Background technique [0002] In the medical field, cerebrospinal fluid drainage (specifically, external ventricular drainage or lumbar drainage) is a very common and effective treatment for neurosurgery clinical treatment, and cerebrospinal fluid drainage generally requires A cerebrospinal fluid drainage system is used. Taking the cerebrospinal fluid drainage system used for external ventricular drainage as an example, it usually includes: a drainage tube and a drainage bag. The patient's ventricle is connected to the drainage bag through the drainage tube, and the cerebrospinal fluid in the patient's ventricle can enter the drainage bag through the drainage tube. The cerebrospinal fluid drainage system currently clinically used in external ventricular drainage has...
