Cerebrospinal fluid detection device used for intraspinal anesthesia

Abstract

The invention belongs to the medical field, and particularly relates to a cerebrospinal fluid detection device used for intraspinal anesthesia. The cerebrospinal fluid detection device comprises a device body. A liquid entering end is arranged at one end of the device body. A vent hole is formed in the other end of the device body. A reagent detection chamber is arranged in the device body and is internally provided with pH test paper. A contrast chamber is arranged beside the reagent detection chamber. The liquid entering end and the reagent detection chamber are communicated with each other through a liquid dropping hole. The vent hole and the reagent detection chamber are communicated through a gas guide hole. The cerebrospinal fluid detection device overcomes the defect for the first time that normal saline and cerebrospinal fluid can not be identified clinically, whether fluid flowing out of a lumbar puncture needle is cerebrospinal fluid or normal saline can be identified, and doctors can confirm the position of the lumbar puncture needle. Meanwhile, the cerebrospinal fluid detection device has the advantages of being simple, visual and rapid in flow.

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. The drug efficacy and physiological effects produced by different anatomical parts of the spinal canal are very different, which in turn affects the effect and safety of clinical anesthesia. At present, there is no clinical detection device for distinguishing between normal saline and cerebrospinal fluid. And no relevant inventions were found in the existing patents.
