Craniocerebral drainage device

Abstract

The invention provides a craniocerebral drainage device. The craniocerebral drainage device comprises a drainage bottle main body, a sliding plate and a scale plate, wherein the drainage bottle main body is arranged on the sliding plate, the sliding plate is arranged on the scale plate, the sliding plate is provided with a connecting sliding hole, a drainage positioning hole and a sampling positioning hole, a connecting post is arranged at the rear side of the drainage bottle main body, the connecting post is mounted in the connecting sliding hole, a separating-preventing baffle ring is arranged at the rear end part of the connecting post, a positioning pressure spring is arranged between the rear side of the sliding plate and the separating-preventing baffle ring, a positioning pin and asampling connecting base are arranged on the drainage bottle main body, and a sampling flow channel is arranged on the sampling connecting base; a sampling baffle is arranged on the sampling connecting base; a negative pressure drainage connector is arranged at the upper part of the drainage bottle main body, a partition wall for partitioning the inside of the drainage bottle main body into a drainage main cavity and a drainage auxiliary cavity is arranged in the drainage bottle main body, and a negative pressure limiting valve is arranged at the upper part of the drainage auxiliary cavity. The craniocerebral drainage device is simple in structure and convenient to use, initial drainage and pipeline dredging are convenient, sampling analysis is convenient, dredging after pipeline blockageis also convenient, and the treatment effect is good.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a brain drainage device with simple structure, convenient use and no accidental risk in the sampling process. Background technique [0002] We know that craniocerebral trauma, effusion lesions, cerebrospinal fluid infection, and cerebral hematoma caused by high blood pressure are common clinical diseases. One of the ways to reduce intracranial pressure is to implant a drainage tube into the brain or lumbar spine, connect a drainage collection device, and drain cerebrospinal fluid, cerebrospinal fluid, and cerebral hematoma out of the brain, thereby reducing intracranial pressure and saving the patient's life. The structure of the brain drainage device is relatively simple, and there are the following inconveniences in clinical use: 1. During the drainage process, it is often necessary to sample and analyze the drainage fluid. The routine operation is to disconnect the drainage tube...

[0002] We know that craniocerebral trauma, effusion lesions, cerebrospinal fluid infection, and cerebral hematoma caused by high blood pressure are common clinical diseases. One of the ways to reduce intracranial pressure is to implant a drainage tube into the brain or lumbar spine, connect a drainage collection device, and drain cerebrospinal fluid, cerebrospinal fluid, and cerebral hematoma out of the brain, thereby reducing intracranial pressure and saving the patient's life. The structure of the brain drainage device is relatively simple, and there are the following inconveniences in clinical use: 1. During the drainage process, it is often necessary to sample and analyze the drainage fluid. The routine operation is to disconnect the drainage tube for sampling. When the drainage tube is disconnected, the drainage fluid is easy to splash and cause cross-infection ; 2. The operation of disconnecting the drainage tube is likely to cause effusion reflux and lead to intracranial infection, and the risk of clinical use is high; 3. The disconnection and connection of the drainage tube is complicated, time-consuming and laborious; For the collection device, the height of the drainage collection device needs to be lowered, and the drainage can be promoted by increasing the height difference. The operation is completely based on clinical experience. If the height difference is too low, drainage cannot be performed, and if the height difference is too large, it will easily cause cerebral herniation, which is very inconvenient to operate; 5. During the drainage process If there is a large blood clot or the thickened blood is likely to cause blockage of the drainage tube, once it is blocked, the drainage system can only be replaced again, which is not only inconvenient to operate, but also likely to cause secondary infection
