Continuous medicine-filling injector

Abstract

The invention discloses a continuous drenching injector, which is applicable to prevention and therapeutic drenching and injection of livestock, poultry and fed wild animals. The continuous drenching injector comprises a small handle, a large handle, a cylinder body, and a pistol-typed structure which is arranged at the front end of the cylinder body and consists of joints which are used for connecting drenching pipe components or injection heads; wherein, the cylinder body is connected with the upper part of the large handle by a connection part; the lower part of the large handle and the small handle are internally provided with the same main spring and connected with each other by a connection pin and a pin buckle; the cylinder body and the large handle are respectively and internally provided with a piston and a piston connection rod which are provided with O-shaped sealing rings; the rear end of the piston connection rod is provided with a channel; the other end of the small handle is embedded into the channel; the upper part of the large handle corresponding to the back part of the small handle at the end is provided with a dosage adjusting net and a thread; and the internalside of the small handle is provided with a liquid suction device which is connected with the piston connection rod by the thread. The continuous drenching injector has the advantages of precise dosage, convenient use of the piston-typed structure, comfortable hand-feeling, light weight of product, good anti-corrosion performance and the like.

Description

technical field [0001] The invention discloses a continuous injection syringe, which is suitable for preventive and therapeutic injection of livestock, poultry and wild animals. Background technique [0002] Syringes disclosed in the prior art mainly include the following types: all-glass syringes, metal syringes, plastic syringes, continuous syringes, infusion sets, and dart syringes. [0003] Among them, the all-glass syringe is composed of a piston and an outer sleeve. When using, the piston is placed in the outer sleeve, and the piston is driven by hand to inject the liquid medicine. However, due to its fragile texture, careful operation is required. It is mostly used for pig ear vein injection and small experimental animal injection. , so the syringe is limited to a very small range of use, which is not conducive to promotion. [0004] Metal syringe, the structure includes a metal sleeve, the front end of which is an injection head for connecting the needle, the outer ...

AI Technical Summary

Problems solved by technology

Although the previous all-glass syringes are accurate in dosage and do not need to adjust the tightness of the piston, they have the disadvantage of being fragile and easy to break; although the metal syringe overcomes the shortcomings of the all-glass syringe, it needs to adjust the piston, which is easy to leak and has a heavy volume. Difficult; the dart syringe is only limited to the anesthesia of wild animals; there is also a disposable plastic syringe in the prior art, but this kind of syringe cannot be applied to veterinary clinics because of the long injection time; Extensive and strong and durable, especially the multifunctional animal injection device that can be used for filling medicine and realizing injection is the purpose of the present invention
