Abstract

The invention discloses a cerebrospinal fluid extracting device which comprises a jugular vein indwelling tube device, a two-sided lateral ventricle indwelling tube device and cauda equine cone indwelling tube device. The two-sided lateral ventricle indwelling tube device comprises a two-sided lateral ventricle indwelling tube and a cerebrospinal fluid volumetric flask, the jugular vein indwelling tube device comprises a jugular vein indwelling tube and an intravenous syringe, and the cauda equine cone indwelling tube device comprises a cauda equine cone indwelling tube and a cerebrospinal fluid collector. The cerebrospinal fluid extracting device has the advantages that the cerebrospinal fluid extracting device is easy and convenient to operate, short in time and stable in operation, can become effective fast and can be used for research experiments on drugs which pass blood brain barriers, diversified nervous system diseases and nervous system disease targeted drug metabolism, intravenous administration can be facilitated, and a large quantity of cerebrospinal fluid can be continuously extracted by the aid of the cerebrospinal fluid extracting device.

Description

technical field [0001] The invention belongs to the field of medical instruments, in particular to a cerebrospinal fluid extraction device. Background technique [0002] Cerebrospinal fluid is a colorless transparent liquid produced by the choroid plexus cells of the ventricle. Its indications reflect the biochemical and pathological conditions of the central nervous system. People have been working on long-term continuous collection and testing of cerebrospinal fluid to study central nervous system diseases, such as Alzheimer's disease and Parkinson's disease. And the study of cerebrospinal fluid is often linked to intravenous administration, in order to obtain practical drugs that can act on the nervous system and penetrate the blood-brain barrier. [0003] Traditionally, cerebrospinal fluid is generally collected by puncture of the cerebellar cisterna magna, each time takes about 20 minutes, and about 100 μl can be collected, but the interval between two times can be as ...
