Injection end structure of injector and injector

Abstract

The invention discloses an injection end structure of an injector and the injector and belongs to the technical field of injectors. The injection end structure of the injector comprises a fixing unit, an elastic unit, a switch unit and at least one needle, wherein the a finger ring hole allowing penetration of a finger is formed in the fixing unit, and the switch unit and the at least one needle are fixed on the fixing unit; the elastic unit comprises a fastening end fixedly connected with the fixing unit as well as a moving end capable of reciprocating under the action of external force and own elasticity to trigger the switch unit. The injector comprises the injection end structure and a liquid supply assembly. The injection end structure of the injector meets the requirement of ergonomics and is quite small in size, liquid medicine can be injected timely through the cooperation of the elastic unit and the switch unit, the injection efficiency is high, and injection is convenient.

Description

technical field [0001] The invention relates to a syringe, in particular to an injection end structure of the syringe and the syringe. Background technique [0002] At present, poultry in large-scale breeding plants need to be vaccinated. Due to the large number of poultry to be injected, syringes are generally required to meet the requirements of continuous injection. Traditional poultry syringes are hand-held, and the piston rod of the syringe A medicine storage bottle loaded with medicine liquid is directly fixed nearby, such as a Chinese utility model patent with a patent number of 02212682.1 and a name called a multifunctional veterinary continuous syringe. Cartridge, this type of syringe has a relatively simple structure, but the problem is that the injection personnel need to hold the syringe for a long time, which greatly increases the workload of the injection personnel and seriously affects the injection efficiency. [0003] For the above technical problems, the C...

Problems solved by technology

[0002] At present, poultry in large-scale breeding plants need to be vaccinated. Due to the large number of poultry to be injected, syringes are generally required to meet the requirements of continuous injection. Traditional poultry syringes are hand-held, and the piston rod of the syringe A medicine storage bottle loaded with medicine liquid is directly fixed nearby, such as a Chinese utility model patent with a patent number of 02212682.1 and a name called a multifunctional veterinary continuous syringe. The structure of this type of syringe is relatively simple, but the problem is that the injection personnel need to hold the syringe for a long time, which greatly increases the workload of the injection personnel and seriously affects the injection efficiency

[0003] For the above technical problems, the Chinese utility model patent No. 201610212564.0, titled a split-type hand-held automatic injector, proposes a technical solution that can solve the problem. It places the mobile power supply and the large-dose vaccine bottle on The waist is connected with the injection end of the syringe by a pipeline. Although the weight of the hand-held part is reduced by this split design, the injection end of the syringe in this way still adopts the structure of a hand-held injection gun, which is bulky And it is not convenient for injection operation, and the injection efficiency is still not ideal
