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 Once the needle is inserted into the wrong position, if it is not withdrawn to check whether it penetrates into an artery or vein, a series of complications will appear due to improper puncture.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

Abstract

The present invention provides a nerve block anesthesia needle, an anesthesia device and a using method thereof. The nerve block anesthesia needle includes a syringe with a cavity and a liquid outlet hole at the front end, a piston core rod matched with the syringe, and a speed-blocking assembly, and the speed-blocking assembly includes a folded arm and a support bladder, so the The barrel wall of the needle cylinder is provided with a notch that penetrates to the cavity, the hinged arm is hinged in the notch, and the hinged arm is connected to the needle through a support bag from an extension end of its hinge point. The inner wall of the cylinder is connected, and the support bag is filled with gas, so that the hinged arm extends from the notch to the cavity from the other extension end of its hinge point; the support bag is provided with an energy A seal that tears and vents gas, and the hinged arm is attached to the seal. Compared with the related art, the nerve block anesthesia needle provided by the present invention has the function of reminding the operator to withdraw, which improves the accuracy of puncture and reduces the discomfort of the patient.

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 method for using the same. Background technique [0002] Nerve block anesthesia is the injection of local anesthetics near the peripheral nerve trunk to block the conduction of nerve impulses to anesthetize the area innervated by the nerve. Local anesthetic is injected around the nerve trunk, plexus, and ganglion to block its impulse conduction and make the innervated area anesthetize. .But there is the possibility of serious complications, so you must be familiar with the local anatomy, understand the tissue that the puncture needle will pass through, as well as the nearby blood vessels, organs and body cavities. Finger (toe) nerve trunk block, cervical plexus, brachial plexus block, as well as stellate ganglion and lumbar sympathetic ganglion block for diagnosis and treatment. [0003] When the anesthetic is ...
