Administration device for anesthesiology department

Abstract

The invention discloses an administration device for anesthesiology department, and effectively solves the problems that an existing anesthesia administration device cannot carry out quantitative injection according to different parts and injection medicines are not uniformly mixed. The administration device comprises a needle cylinder, a baffle plate is fixed at right end of needle cylinder, a supporting plate is fixed to the right side of the baffle plate, a piston is slidably connected into the needle cylinder, a push rod is fixed at right end of piston, the push rod is in threaded connection with a sleeve, an ejector rod capable of moving left and right is arranged on the front side of the supporting plate, a full gear capable of rotating leftwards and rightwards is arranged on the front side of the supporting plate, the full gear generates forward and reverse rotation along with the left-right movement of the ejector rod, a dial coaxial with the full gear is fixed to the front side of the supporting plate, a pointer capable of being matched with the dial is fixed to the front end face of the full gear, a plurality of scale marks are evenly distributed on the outer edge face ofthe needle cylinder, a stirring shaft is coaxially and rotationally connected to the left end in the needle cylinder, the right end of the stirring shaft extends into the push rod and is in threadedconnection with the push rod, and a plurality of telescopic stirring blades are arranged on the stirring shaft; the device is novel in concept, ingenious in structure, convenient to operate and high in practicability.

Description

technical field [0001] The invention relates to the technical field of anesthesia appliances, in particular to a drug delivery device for anesthesia department. Background technique [0002] Oral local anesthesia, referred to as local anesthesia, refers to the use of local anesthetic drugs to temporarily block the sensory conduction of nerve endings and fibers in a certain area of ​​the body, so that the pain in this area disappears. [0003] The existing oral local anesthesia injection device is extremely inconvenient to use, especially when different parts are anesthetized, the required dosage is different. Because it is in the oral cavity, it is not easy to observe the injection process and dosage, resulting in a large amount of injection. Inaccurate will affect the effect of anesthesia and treatment, and it is generally necessary to add appropriate amount of epinephrine and other vasoconstrictor drugs to the anesthesia drug, and the anesthesia drug in the syringe is mixe...
