Injector for wild animals

Abstract

An injector for wild animals comprises a needle head, a double-end piston, a front needle cylinder, a springback limiting device, a middle connecting sleeve, a rear piston cylinder, a sliding rod and a power starting device. The springback limiting device is mounted at the front end of the front needle cylinder and internally provided with a needle head; two ends of the double-end piston are respectively in tight sliding connection with the inner walls of the front needle cylinder and the rear piston cylinder; the power starting device is fixedly mounted at the rear end of the rear piston cylinder; the rear end of the sliding rod is fixedly installed in the middle of the double-end piston. When the double-end piston is pushed to the bottom of the front needle cylinder, the front end of the sliding rod triggers the springback limiting device. The springback limiting device is arranged to be matched with the sliding rod; after medicine injection in the front needle cylinder is completed, the needle retracts to be separated from the animal body, and secondary injury of the needle to wild animals is avoided; then, a power starting device is arranged, medicine injection is conducted under the inertia effect, and the quality is guaranteed; in addition, the injection can be repeatedly used for injection, so that the overall utilization rate of the injector is improved.

Description

technical field [0001] The invention relates to the technical field of medical injection tools, in particular to a syringe for wild animals. Background technique [0002] Syringes are one of the most commonly used medical devices in medicine today. They are often used for medical examination and treatment. The main specific uses include intramuscular injection of drugs, intravenous injection of drugs, subcutaneous injection of drugs, and extraction of body fluids. Nowadays, the production of syringes has reached a considerable scale. According to different clinical needs, the types of syringes are also varied; how to inject medicines into wild animals has always been a problem for veterinarians, especially those who are large in size, violent in character, and aggressive. aggressive wild animals; [0003] For example, the Chinese utility model patent with publication number CN2220293 discloses a long-distance automatic injector, which includes a needle, a syringe, and a pis...
