Problems solved by technology
None of these currently used anesthesia needles has a reminder function for withdrawal. Once the needle is inserted into the wrong position, if it is not withdrawn to check whether it penetrates into an artery or vein, a series of complications will appear due to improper puncture. patient brings pain

The invention provides a nerve block anesthetic needle, an anesthetic device and a using method thereof. The nerve block anesthetic needle comprises a needle cylinder, a piston core rod and a speed blocking assembly, the needle cylinder is provided with a cavity, a liquid outlet hole is formed in the front end of the needle cylinder, the piston core rod is matched with the needle cylinder, the speed blocking assembly comprises a folding arm and a supporting bag, a notch communicated with the cavity is formed in the cylinder wall of the needle cylinder, and the folding arm is hinged into the notch. The folding arm is connected with the inner wall of the needle cylinder through a supporting bag body from one extending end of the hinge point of the folding arm, and the supporting bag body isfilled with gas, so that the folding arm extends into the cavity from the notch from the other extending end of the hinge point of the folding arm; a sealing strip capable of being torn and exhaustinggas is arranged on the supporting bag body, and the folding arm is adhered to the sealing strip. Compared with the prior art, the nerve block anesthetic needle provided by the invention has the function of reminding an operator of withdrawing, the puncture accuracy is improved, and the discomfort of a patient is reduced.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a nerve block anesthesia needle, an anesthesia device and a use method thereof. Background technique [0002] Nerve block anesthesia is the injection of local anesthetics near the peripheral nerve trunk to anesthetize the area innervated by the nerve by blocking the conduction of nerve impulses. Inject local anesthetics around nerve trunks, plexuses, and nodes to block their impulse conduction and anesthetize the innervated area, which is called nerve block. Only one injection of nerve block is required 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 passes through, and the nearby blood vessels, organs and body cavities. Commonly used nerve blocks can help interstitial, infraorbital, sciatic, and Finger (toe) nerve trunk block...
