A split-type hand-held automatic injector

Abstract

The invention relates to an automatic split-type handheld syringe. The automatic split-type handheld syringe comprises a shell, a circuit system, a lead screw nut transmission mechanism and an injection pipe; one end of an external connecting wire of the circuit system is connected with an external mobile power supply; the circuit system controls and drives the lead screw nut mechanism to move in a reciprocating manner; one-time reciprocating movement of the lead screw nut mechanism implements one-time vaccine injection of the injection pipe; the injection pipe is fixedly connected with a liquid inlet, and the liquid inlet is connected with a liquid suction connector or a medicine bottle fixer; one end of a liquid inlet hose is connected with the liquid suction connector, and the other end of the liquid inlet hose is connected with a large-dose vaccine bottle; and the medicine bottle fixer is used for directly inserting a small-dose vaccine bottle. In the automatic split-type handheld syringe, by virtue of a split-type design for separately arranging the mobile power supply and the large-dose vaccine bottle at the waist when in work, the weight of a handheld part is reduced, and the long-time power supply can be realized; the injection dose is adjustable and precise, and the injection dose can meet different requirements of the vaccine injection; and by virtue of an injection button, the automatic one-time injection is realized, and the operation is simple and quick.

Description

technical field [0001] The invention relates to the field of poultry vaccine injection in farms, in particular to a split-type hand-held automatic injector. Background technique [0002] my country's poultry and livestock breeding mode has gradually shifted from individual free-range breeding mode to professional and intensive breeding mode. Vaccination is a labor-intensive operation that requires experienced vaccinators and prolonged injection operations. At the same time, in recent years, the outbreaks of bird flu and swine flu have continued, and the number of vaccinations has become more frequent, which has doubled the workload of farmers and veterinary epidemic prevention personnel. [0003] The traditional syringe vaccine injection process needs to be advanced manually, and the operator needs to operate with one hand for a long time. The injection speed is slow and it is easy to cause damage to the injection site. With the development of electromechanical technology,...

Problems solved by technology

[0003] The traditional syringe vaccine injection process needs to be manually advanced, and the operator needs to operate with one hand for a long time. The injection rate is slow and it is easy to cause damage to the injection site. The operator has high technical requirements, the injection accuracy is not high, and the inoculation dose of each bird cannot be guaranteed.

With the development of electromechanical technology, some other automatic injectors have appeared. In the published patents with patent numbers 2011103298019 and 2006101190441, they are respectively applied to the injection of chemical reagents and medical reagents to realize the automation of a single injection, but their functions still have the following Problems: (1) The continuous supply of vaccines cannot be achieved during the injection process; (2) The battery is built into the gun body, which may cause insufficient power supply and increase the weight of the cavity during continuous operation; (3) The injection dose cannot be adjusted, Does not meet the different needs of different poultry vaccine single injection doses
