Description

Cerebrospinal fluid anti-reflux detection device for spinal anesthesia

technical field

The utility model relates to the field of cerebrospinal fluid detection for intraspinal anesthesia, in particular to a cerebrospinal fluid anti-reflux detection device for intraspinal anesthesia.

Background technique

Anesthesiologists perform spinal anesthesia, especially when combined spinal and epidural anesthesia, because the resistance disappearance method is used to determine the position of the epidural space, so it is impossible to distinguish whether the liquid drained by the lumbar puncture needle is cerebrospinal fluid or normal saline. The location of the puncture needle cannot be determined. The drug efficacy and tissue damage caused by drug administration in different anatomical sites in the spinal canal or subsequent operations are very different, which seriously affects the efficacy and safety of clinical anesthesia.

Previous literature suggests that cerebrospinal fluid contains sugar, while normal saline does not. Therefore, testing whether sugar is present can effectively distinguish cerebrospinal fluid from normal saline, with an accuracy rate of 100%. The glucose test strip changes color when it encounters sugar, which is simpler and more intuitive than the interval change of the PH color card. In the existing cerebrospinal fluid anti-reflux detection device for spinal anesthesia, in terms of anti-reflux, the air pressure in the device is mainly controlled by a one-way valve, thereby preventing the liquid from refluxing. This solution has the following problems:

(1) The backflow problem cannot be solved due to the poor sealing of the device or the aging of the equipment, and a new valve needs to be replaced;

(2) The valve is controlled manually, and the operation is complicated.

In terms of detection, liquid detection is mainly carried out through pH test paper. This solution has the following problems:

(1) Because the pH value of cerebrospinal fluid and normal saline is not very different, the results obtained by pH test paper should not be distinguished; and the results after pH change need to be compared with the color card, which is more complicated.

(2) It is necessary to observe through the perspective window, which is inconvenient to observe.
