Cerebrospinal fluid detection apparatus for intraspinal anesthesia

The invention belongs to the field of medical treatment, and particularly relates to a cerebrospinal fluid detection apparatus for intraspinal anesthesia. The cerebrospinal fluid detection apparatus comprises an apparatus body, a liquid inlet end and a ventilation drug injecting end is arranged on the apparatus end, a reagent detection chamber is arranged in the apparatus body, the liquid inlet end and the reagent detection chamber are intercommunicated through a dripping hole, a ventilation hole and the reagent detection chamber are intercommunicated through an air guide hole, a first one-way valve is used for sealing the air guide hole is arranged in the air guide hole, and a second one-way valve used for sealing the dripping hole is arranged in the dripping hole. Since cerebrospinal fluid and test paper have chemical reaction, the cerebrospinal fluid contacting with the test paper can be prevented from flowing into a spinal-anesthesia puncture needle by the aid of design of the dripping hole and the valves
