Local anesthesia drug spraying gun

Abstract

The invention discloses a local anesthesia drug spraying gun. The local anesthesia drug spraying gun comprises a pistol-shaped casing, a handle part of the casing is provided with a local anesthesia drug inlet, the local anesthesia inlet is communicated with a drug storage chamber in the bottom, the drug storage chamber is communicated with one end of a drug feeding guide pipe, and the other end of the drug feeding guide pipe is connected with a drug inlet valve on a spraying pipe; the spraying pipe is also provided with a piston, the piston is connected with a trigger and sleeved with a spring, the front end of the spraying pipe is provided with a drug outlet valve, the drug outlet valve is connected with a conversion head, and the conversion head is connected with a spraying head througha spraying drug pipe. The local anesthesia drug spraying gun has the advantages that the operation is convenient, a spraying chamber pipe can be freely rotated, local anesthesia of the pharynx and throat part is fully perfected and conducted, the dosage of a local anesthesia drug is precisely calculated, and the whole local anesthesia drug spraying gun is transparent and is a plastic product which is low in price and can be used by one person for one purpose and can reduce cross infection.

Description

technical field [0001] The invention belongs to the technical field of medical devices and relates to a local anesthetic spray gun. Background technique [0002] Good and complete local anesthesia can greatly reduce adverse reactions during endotracheal intubation, such as hypertension, arrhythmia, etc., and is also a necessary operation for endotracheal intubation through the nasal cavity. Currently, the commonly used local anesthetic watering can in clinical practice needs two hands or two people to operate and spray the local anesthetic by squeezing the distal balloon, which is inconvenient to operate; the spray tube can only spray in one direction and cannot rotate the direction; there is no The scale makes it impossible to accurately calculate the volume of local anesthetics; the front end of the nozzle is a metal tube, and the watering can is used repeatedly and cannot be sterilized, which may easily cause cross-infection.
