Abstract

The invention provides an anesthesia flying needle for an animal. The anesthesia flying needle comprises an injecting device and a launching device. The injecting device comprises a needle head and a syringe. The syringe is internally provided with a first piston and a first connecting rod, the tail end of the first connecting rod is located outside the syringe, and an elastic resetting device is arranged between the tail end of the first connecting rod and the syringe. The launching device comprises a launching cylinder, a pressure cylinder, a second piston and a second connecting rod, the internal diameter of the launching cylinder is smaller than that of the pressure cylinder, the launching cylinder communicates with the pressure cylinder, and when the second piston is located in the pressure cylinder, one end of the second connecting rod is connected with the second piston, and a pressing device is arranged at the other end of the second piston. By means of cooperation between the needle head with a side hole and a sliding block playing a blocking role, before the needle head enters the animal body, liquid medicine in the syringe will not leak out; after the needle head enters the animal body, the sliding block is pushed open, and the liquid medicine in the syringe enters the animal body through the side hole.

Description

technical field [0001] The invention belongs to the field of animal anesthesia appliances, in particular to an anesthesia flying needle for 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, and there are various types of syringes according to different clinical needs. [0003] How to inject drugs to animals has always been a problem for veterinarians, especially wild animals with large size, violent personality and strong aggressiveness. Some wild animals and domesticated animals with a low degree of domestication, such as sika deer, are difficult for veterinary personnel to access when injecting anesthetics. Anesthesia a...
