Description

Follow-up regulation fixing frame for ventricular external drainage

Technical Field

The utility model relates to a fixing frame for the following adjustment of the ventricular external drainage.

Background

The drainage outside the cerebrospinal fluid means that the drainage tube is placed into a cerebral ventricle or a lumbar vertebral canal to continuously drain the cerebrospinal fluid, so that the drainage tube can achieve the effect of reducing intracranial pressure and can promote the drainage of inflammatory cerebrospinal fluid or bloody cerebrospinal fluid to achieve the effects of cleaning the cerebrospinal fluid, assisting in treating the inflammation of the cerebral ventricle and preventing hydrocephalus caused by fiber adhesion. The most important thing of continuous external drainage of cerebrospinal fluid is how to control the drainage speed of cerebrospinal fluid, excessive drainage can be caused at too high speed, acute cerebral hernia is formed and endangers life, drainage is unsmooth at too low speed, finally, because the inner diameter of the drainage tube is small, blockage of the tube is easily caused, and finally, the intracranial infection is formed or further aggravated. The formation amount of cerebrospinal fluid of human brain per day is basically constant, about 500ml/d, the cerebrospinal fluid is mainly slowly released by ventricular choroid, in the drainage process, the drainage speed which keeps continuous and balanced is the most critical, and the key for determining the drainage speed is that the drainage device is hung at the horizontal relative height of an external auditory canal, the hanging height is generally required to be 10-15 cm above the horizontal line of the external auditory canal, and the height is not accurate enough by visual inspection in the past.
