Description

Nerve block anesthesia needle, anesthesia device and use method thereof

Technical Field

The invention relates to the technical field of medical equipment, in particular to a nerve block anesthesia needle, an anesthesia device and a using method thereof.

Background

Nerve block anesthesia is a method in which a local anesthetic is injected near a peripheral nerve trunk to block conduction of nerve impulses, thereby anesthetizing a region innervated by nerves. Local anesthetic is injected around nerve trunk, plexus and node to block its impulse conduction, so that the innervated area produces anesthesia, called nerve block. The nerve block only needs one injection to obtain a larger anesthesia area. However, since there is a possibility of causing serious complications, it is necessary to be familiar with the local anatomy and understand the tissue through which the puncture needle passes, and the blood vessel, organ, body cavity, and the like in the vicinity. The commonly used nerve block is helpful for the blocking of the interorbital, infraorbital, ischiadic and phalangeal nerve trunk, the cervical plexus, brachial plexus, and the stellate ganglion and lumbar sympathetic ganglion for diagnosis and treatment.

When the anesthetic is injected, the anesthetic is pushed backwards, inwards and downwards at a proper position, and when a patient feels strange feeling of radiating to fingers, wrists or forearms, the advance is stopped, and if blood or air is not pumped back, the liquid medicine is injected. Therefore, during the injection of the anesthetic, the withdrawal is important, and the complications caused by improper puncture can be effectively avoided.
