Anesthesia medicine spraying device for anesthesia department nursing and cleaning method of spraying nozzle

Technical Field

The invention belongs to the field of anesthesia department nursing, and particularly relates to an anesthetic spraying device for anesthesia department nursing and a cleaning method of a spraying nozzle.

Background

Anesthesia is divided into local anesthesia and general anesthesia, while local anesthesia is mostly used in surgical operations, for example, when a patient has a trauma, medical staff firstly debrides the trauma and then disinfects the trauma, then an anesthetic is used, the anesthetic is used for infiltration anesthesia (belonging to local anesthesia) around the wound, and the local anesthetic is injected around the wound and can play a role in temporarily blocking local nerves. The local anesthetic can be anesthetized for about half an hour generally, the drug effect of the anesthetic is reduced after half an hour, and the body of a patient can feel painful. Local anesthesia care methods generally include local injection methods and spraying methods. The common anesthetics used for the spray anesthesia include lidocaine, tetracaine and procaine hydrochloride, the dosage for local anesthesia is 0.5-1% of solution, the dosage for each time cannot exceed 1g, and the 0.1% solution is commonly used for intravenous injection. Other local anesthetics commonly used in the prior art are mostly western medicines, the dosage of the anesthetics cannot be well controlled and is performed according to the experience of doctors, some patients are inherently allergic to the anesthetics, and serious medical accidents can occur if the anesthetics are improperly injected by doctors in an anesthesia department;
