Cerebrospinal fluid detection apparatus for intraspinal anesthesia

Abstract

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, and safe implementation of combined spinal epidural anesthesia is guaranteed; the apparatus is no need to be taken off in injection of local anesthetic drugs by the design of the valves, displacement of the spinal-anesthesia puncture needle is avoided to a certain degree, and convenience, efficiency and safety in anesthesia operation are guaranteed.

Description

technical field [0001] The invention belongs to the field of medical treatment, in particular to a cerebrospinal fluid detection device for intraspinal anesthesia. Background technique [0002] When anesthesiologists perform spinal anesthesia, especially combined spinal epidural anesthesia, they cannot distinguish whether the fluid drained by the lumbar puncture needle is cerebrospinal fluid or saline because they use normal saline to determine the location of the epidural space by the method of resistance loss. There is no way to determine where the puncture needle is located. Drug efficacy and tissue damage caused by administration of different anatomical parts of the spinal canal or subsequent operations are very different, which seriously affects the effect and safety of clinical anesthesia. [0003] In 2015, the applicant applied for an invention patent titled "a cerebrospinal fluid detection device for spinal anesthesia", and its technical solution is: a cerebrospinal...

Problems solved by technology

[0004] Although the above-mentioned patent can prevent the cerebrospinal fluid in contact with the test paper from flowing back into the liquid inlet to a certain extent, when the local anesthetic is injected, the device needs to be removed, which makes the steps of injecting the drug too cumbersome and may cause spinal anesthesia. The possibility of displacement and thus affecting the effect of anesthesia
