Cerebrospinal fluid quantitative drainage device

Abstract

The invention discloses a cerebrospinal fluid quantitative drainage device. The device comprises a drainage tube, a pressing valve, an adjusting mechanism, a detection mechanism and a drainage bag, the drainage tube is sequentially connected with the pressing valve, the adjusting mechanism, the detection mechanism and the drainage bag, the adjusting mechanism is provided with an oval container, a branch pipe, a lifting ball, a spring, an adjusting plate, a protective sleeve, a driving bevel gear, a driven bevel gear, a screw, an adjusting rod and an adjusting knob, and the upper end of the oval container communicates with the drainage pipe. According to the device, the pressing valve can be pressed to avoid precipitation after cerebrospinal fluid is precipitated in a pipeline, a filtering mechanism can filter a plurality of large tissues or clots to prevent the pipeline from being blocked, in addition, the adjusting mechanism and the detection mechanism are used in cooperation, a displayer displays the pressure of the upper end face of the lifting ball in real time, the adjusting knob is screwed according to needs to achieve lifting of an adjusting plate so as to adjust the elasticity of the spring, the elasticity of the spring can reach a preset pressure value, and when intracranial pressure is larger than the preset value, the lifting ball is pressed downwards to enable the cerebrospinal fluid to flow out of the branch pipe and be drained into the drainage bag.

Description

technical field [0001] The invention belongs to medical equipment, in particular to a quantitative drainage device for cerebrospinal fluid. Background technique [0002] After some neurosurgery operations, it is necessary to drain the cerebrospinal fluid in the brain to achieve a dynamic balance of intracranial pressure, so as to avoid excessive intracranial pressure from affecting the patient's recovery. The existing cerebrospinal fluid drainage device has a simple structure and can The inaccurate control of the drainage volume and easy blockage will result in excessive or insufficient drainage, which will seriously affect the recovery of patients. Contents of the invention [0003] In order to solve the above problems, the present invention discloses a quantitative cerebrospinal fluid drainage device, which can adjust the drainage volume according to the cerebrospinal fluid drainage demand, control the drainage of cerebrospinal fluid according to the preset intracranial ...
