Injection device for animals

Abstract

The invention discloses an animal injection device, which comprises an injection tube and a push rod. The left end of the syringe is provided with an injection needle, and the left end of the push rod is provided with a piston matching the injection tube. It is characterized in that the piston The left and right sides of the injection tube respectively form a drug injection area and an air cavity, the right end of the injection tube is provided with a sealing plate, and the sealing plate is provided with a flexible tube communicating with the air cavity, and the end of the flexible tube is Features hand grip airbags. The invention has very obvious beneficial effects: simple and stable structure, low cost, convenient installation, disassembly and use, high work efficiency, good safety performance and experimental accuracy, and can be used repeatedly.

Description

technical field [0001] The invention relates to the technical field of medical instruments, and more specifically relates to a structure of an animal injection device. Background technique [0002] In the process of pathological research, researchers often need animal experiments. Intravenous administration of drugs to animals is a type of pathological research. Currently, researchers generally position the animal with a clamp, and then inject the drug into the animal's muscle tissue through a syringe. In this process, the animal clamps are increased, the cost is high, and the clamping of the animals is a waste of time, and there is also the problem of low work efficiency. However, the structure of the general injection device in the prior art does not effectively solve the above problems. For example, Chinese Patent Announcement No. CN 2039204 U, announced on June 14, 1989, the name of the invention is the airbag type disposable ampoule syringe. The combined innovation ...
