Fluid drainage device for brain tumor surgery

Abstract

The invention discloses a fluid drainage device for a brain tumor surgery. The device comprises a fluid storage tank body, a drainage tube, an air suction tube and a negative pressure device, and thenegative pressure device mainly comprises a small air pump; the small air pump is provided with a gas pump suction nozzle, air suction joints are fixedly inserted into both ends of the air suction tube, the air suction joints and the air suction tube adopt an integral structure, and one end of the air suction tube is inserted into the gas pump suction nozzle through the air suction joints; the device is in the process of actual drainage, the fluid can enter the bottom layer of the fluid storage tank by flipping a liquid separation plate to the vertical state or the inclined state, when the storage reaches a certain amount or the secondary liquid is extracted, the lowermost liquid separation plate is flipped to the horizontal position, the liquid separation plate can be used for achieving the partitioning action, so that the fluid is continuously pumped in order, and multiple-fluid extracting is stored separately so as to avoid the confusing effect caused by the accumulated fluid of multiple fluid taking.

Description

Technical field [0001] The invention relates to the medical field, in particular to a effusion drainage device for brain tumor surgery. Background technique [0002] The secretion and absorption of normal cerebrospinal fluid are often in dynamic equilibrium. In pathological conditions, excessive intracranial cerebrospinal fluid accumulates in the ventricular system, or sometimes accumulates in the subarachnoid space, and most of the intracranial pressure increases, which is called hydrocephalus. When the cerebrospinal fluid circulatory system is obstructed in any part, hydrocephalus will appear, and hydrocephalus caused by brain tumors is the most common. [0003] Hydrocephalus is generally treated with drainage therapy. Normally, the pathological phenomena of hydrocephalus drawn at different times are different. However, the existing drainage devices mostly use one drainage bag, so the effusions drawn from different periods are mostly mixed together. It is easy to cause confusio...

Problems solved by technology

[0003] Hydrocephalus generally adopts drainage therapy. Usually, the pathological phenomena of hydrocephalus extracted at different time periods are different. However, the existing drainage devices mostly use one drainage bag, so the effusions extracted from different periods are mostly mixed together, so It is easy to cause effusion confusion, making it difficult to observe pathological features
