Nerve block injection test device

Abstract

The invention discloses a nerve block injection test device. The device comprises a nerve block puncture needle, a liquid injection catheter, an injector, an injection pump and a treadle type filling injector; the liquid inlet end of the nerve block puncture needle is connected with the liquid outlet end of the liquid injection catheter; the liquid inlet end of the liquid injection catheter is connected with the liquid outlet end of the injector; the injector is clamped on the injection pump; the treadle type filling injector is connected with the injection pump through signal conveying lines. The device has the advantages that when in implementation, a doctor holds an ultrasonic probe by one hand so that a part which needs anesthetization on a patient body can develop on a computer, the doctor holds the nerve block puncture needle by the other hand to conduct puncture on the corresponding part which needs anesthetization, and then the filling injection of narcotic liquid can be completed by stepping on the corresponding treadle type filling injector, so that the troubles can be omitted that the doctor talks to another doctor and guides another doctor to hold the injector and push the narcotic medicine to a narcotic part, then the injection test work can be completed only by one doctor, and thus the labor can be saved, and the working efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a nerve block test injection device. Background technique [0002] Nerve block, as the name suggests, is to inject local anesthetic around the nerve trunk, plexus, and node to block its impulse conduction and anesthetize the innervated area. [0003] Nerve block only needs to be injected in one place to obtain a larger area of ​​anesthesia, but it may cause serious complications. Therefore, it is necessary to be familiar with the local anatomy, understand the tissues that the puncture needle will pass through, and the nearby blood vessels, organs and organs. body cavity etc. [0004] Commonly used nerve blocks include interstitial, infraorbital, sciatic, and digital (toe) nerve trunk blocks, cervical plexus, brachial plexus blocks, and stellate ganglion and lumbar sympathetic ganglion blocks for diagnosis and treatment. [0005] However, in the prior art, when a docto...

AI Technical Summary

Problems solved by technology

[0007] Specifically, on the one hand, at least two doctors are required to cooperate with the patient to perform nerve block test injection, which takes up manpower and increases labor costs; on the other hand, when two doctors cooperate with the operation, if If it is not good, it will take a long time for nerve block test injection, which will increase the workload of doctors and reduce work efficiency
