Problems solved by technology

[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. Unable to determine the position of the puncture needle
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

Embodiment 1

[0023] A cerebrospinal fluid detection device for intraspinal anesthesia includes a device body 1, one end of the device body 1 is provided with a liquid inlet port 2, and the other end of the device body 1 is provided with a ventilation hole 4, and the device body 1 A reagent detection chamber 3 is arranged inside, and a pH test paper is arranged in the reagent detection chamber 3, and a control chamber 5 is arranged beside the reagent detection chamber 3, and the liquid inlet port 2 and the reagent detection chamber 3 pass through a drip hole 8 communicate with each other, and the ventilation hole 4 communicates with the reagent detection chamber 3 through the air guide hole 7 . This application solves the problem of being unable to distinguish between normal saline and cerebrospinal fluid clinically for the first time, and can distinguish whether the fluid drained by the lumbar puncture needle is cerebrospinal fluid or normal saline, so that doctors can determine the locatio...

Embodiment 2

[0025] A cerebrospinal fluid detection device for intraspinal anesthesia includes a device body 1, one end of the device body 1 is provided with a liquid inlet port 2, and the other end of the device body 1 is provided with a ventilation hole 4, and the device body 1 A reagent detection chamber 3 is arranged inside, and a pH test paper is arranged in the reagent detection chamber 3, and a control chamber 5 is arranged beside the reagent detection chamber 3, and the liquid inlet port 2 and the reagent detection chamber 3 pass through a drip hole 8 communicate with each other, and the ventilation hole 4 communicates with the reagent detection chamber 3 through the air guide hole 7 .

[0026] The control chamber 5 is provided with pH neutral color test paper used for the color of the pH test paper in the reagent detection chamber 3, that is, the control chamber is provided with test paper for comparison. pH neutral color test paper is the color of pH test paper when it meets cere...

Embodiment 3

[0036] A cerebrospinal fluid detection device for intraspinal anesthesia includes a device body 1, one end of the device body 1 is provided with a liquid inlet port 2, and the other end of the device body 1 is provided with a ventilation hole 4, and the device body 1 A reagent detection chamber 3 is arranged inside, and a pH test paper is arranged in the reagent detection chamber 3, and a control chamber 5 is arranged beside the reagent detection chamber 3, and the liquid inlet port 2 and the reagent detection chamber 3 pass through a drip hole 8 communicate with each other, and the ventilation hole 4 communicates with the reagent detection chamber 3 through the air guide hole 7 .

[0037] The control chamber 5 is set as a neutral color for the color of the pH test paper in the contrast reagent detection chamber 3, that is, the control chamber itself is set as a neutral color. The pH neutral color is the color of the pH test paper when it meets the cerebrospinal fluid.

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.
