Injector easy in medicine dispensation

Abstract

The invention relates to an injector easy in medicine dispensation. The injector easy in medicine dispensation comprises a needle cylinder and a push rod; a piston plate is arranged at an end part of the push rod; the piston plate can perform airtight reciprocating sliding along the inner wall of the needle cylinder; a limiting plate is fixedly arranged on the inner wall of the needle cylinder; the push rod passes through the limiting plate and can perform reciprocating drawing relative to the limiting plate; a stirring rod is further arranged in the needle cylinder; the stirring rod is parallel with the push rod; a stirring sheet is arranged at one end, passing through the piston plate, of the stirring rod; a picking sheet is arranged at the other end, passing through the limiting plate, of the stirring rod; a tension spring is connected between the picking sheet and the limiting plate; the stirring rod and the piston plate maintain airtight connection; and the stirring rod can perform reciprocating drawing relative to the push rod. The injector is novel and unique in structure, and can effectively simplify the medicine dispensation flow and greatly improve medicine and injection efficiency; the injector reduces the work pressure of a medical worker, and effectively prevents medicine waste, medicine residue and pollution.

Description

technical field [0001] The present invention relates to a medical product, in particular, a syringe. Background technique [0002] In the field of medical treatment, it is often necessary to mix and prepare multiple drugs before injecting them into the human body; the traditional method is to inject multiple liquid medicines into a spare container, and by continuously pumping the liquid medicines, the medicines can be made as quickly as possible. Fusion; in order to ensure the cleanliness of the medicinal liquid, the spare container often adopts an air-tight structure. Therefore, it is extremely laborious to use a syringe to draw the medicinal liquid. During this process, the bottle body needs to be shaken continuously to accelerate the mixing of the medicinal liquid; After mixing, the needle is used to suck out the medicine. Since there is always medicine remaining in the spare container, this process will cause waste of medicine. It can be seen that the dispensing proces...

[0002] In the medical field, it is often necessary to mix and prepare a variety of drugs before injecting them into the human body to treat patients; the traditional method is to inject a variety of liquid medicines into a spare container, and to make the drugs as soon as possible by continuously pumping the liquid medicine. Fusion; in order to ensure the cleanliness of the liquid medicine, the spare container often adopts an airtight structure. Therefore, it is extremely laborious to use a syringe to suck the liquid medicine. During this process, the bottle needs to be shaken continuously to speed up the mixing of the liquid medicine; After the mixing is completed, the drug is sucked out with a needle tube. Since there is always a drug remaining in the spare container, this process will cause a waste of the drug; it can be seen that the dispensing process is extremely time-consuming and seriously affects the efficiency of diagnosis and treatment; In addition, After each diagnosis and treatment, the spare container needs to be cleaned and disinfected, and the post-processing and preparation work is more cumbersome. Therefore, the traditional dispensing injection has great inconvenience
