Negative pressure detection device and detection method for epidural anesthesia

Abstract

A negative pressure detection device for epidural anesthesia disclosed by the present invention comprises a detection cylinder, the left end of the detection cylinder is fixedly connected with a metal block, the left side of the metal block is provided with a positioning device, the left end of the metal block is fixedly connected with a protective cover, and the interior of the detection cylinder is slidably connected with a first piston block in a sealed manner. A glass tube fixedly penetrates through the center position of the first piston block, the left end of the glass tube is communicated with a needle tube, and the left end of the needle tube penetrates through the inner wall of the left side of the detection cylinder, the metal block and the protective cover. A negative pressure detection method for epidural anesthesia comprises the following steps that S1, a to-be-detected part of a patient is made to be horizontal, and the detected part is wiped and disinfected; s2, a threaded rod is rotated through a rotating block, a first piston block and a second piston block are moved, and most of the needle tube is located in the detection cylinder and the protective cover. The negative pressure detection device has the advantages that operation is simple, negative pressure detection work can be stably carried out, and the detection result is accurate and effective.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a negative pressure detection device and detection method for epidural anesthesia. Background technique [0002] Epidural anesthesia (also known as epidural block) is one of the anesthesia techniques widely used clinically, because of its small effect on cardiovascular, respiratory and gastrointestinal functions, definite analgesic effect, muscle relaxation Good, economical and practical, it has always played an irreplaceable role in clinical anesthesia and pain treatment. The scope of epidural block includes: surgical anesthesia, postoperative analgesia, labor analgesia, pain treatment of the neck, chest, abdomen, lumbar base, perineum, lower limbs and feet. Major abdominal surgery, etc. [0003] Before performing epidural anesthesia, it is necessary to find the epidural space of the anesthesia site to ensure that the anesthetic agent is effectively injected into the e...

Problems solved by technology

[0003] Before performing epidural anesthesia, it is necessary to find the epidural space of the anesthesia site to ensure that the anesthetic agent is effectively injected into the epidural space. The way to find the epidural space is usually to use a negative pressure detection device for negative pressure experiments. Existing The most convenient experimental method is to use a syringe to measure the negative pressure, that is, insert the syringe filled with air or liquid into the experimental position, push the syringe manually, and judge whether there is resistance, so as to judge whether it is located in the epidural space. The feeling is not accurate enough, and the needle of the syringe is easily blocked by human cells during the detection process, which in turn causes injection resistance and affects the experimental judgment
