Description

A cerebrospinal fluid drainage device

technical field

The utility model belongs to the technical field of medical equipment and relates to a cerebrospinal fluid drainage device.

Background technique

Cerebrospinal fluid leak is a common complication of spinal surgery. Negative pressure drainage will be placed in the wound cavity after conventional spinal surgery to suck out the accumulated blood in the wound cavity and prevent incision infection and surgical adhesion. For patients with cerebrospinal fluid leaks, negative pressure drainage will also drain cerebrospinal fluid. The amount of cerebrospinal fluid produced in an adult is about 450ml/24h, and when the drainage exceeds 100ml/24h, the patient may experience headaches, vomiting, and even brain herniation. In clinical work, the speed of cerebrospinal fluid leakage is usually judged according to the color and drainage volume of the drainage fluid. When the drainage fluid tends to be red, it is mainly blood at this time, and it needs to be sucked out with negative pressure to prevent infection. And when the drainage fluid tends to be clear, the cerebrospinal fluid is the main source at this time, and positive pressure drainage is required to prevent the cerebrospinal fluid from being excessively drawn out and causing serious consequences. Existing drainage catheters are relatively thin, and are easily twisted and folded during the drainage process. Due to factors such as bloody cerebrospinal fluid, increased flocs caused by infection, and increased protein content, the catheter is often blocked during the drainage process, requiring repeated punctures, causing patients The comprehensive cost of secondary injury and treatment increases; after the successful placement of the drainage tube, it cannot be effectively fixed and easily falls off. Repeated placement increases the infection rate, delays the treatment time, and is not conducive to the recovery of patients.
