Pascal disposable subcutaneous intramuscular injector

Abstract

The invention relates to a Pascal disposable subcutaneous intramuscular injector. The Pascal disposable subcutaneous intramuscular injector consists of a cylinder body, a piston I, a piston shaft, a piston handle and a cover, wherein the piston I is mounted in the cylinder body; the piston shaft is fixedly connected with the piston I; the piston handle penetrates through the cover to be fixedly connected with the piston shaft; a fluid channel is formed in the middle part of the piston handle, the middle part of the piston shaft and the middle part of the piston I; a one-way valve is arranged on the piston I; a compression spring is arranged between the cover and the piston I; an arc-shaped plate is arranged at the lower end of the cylinder body; a piston II is also arranged in the cylinderbody, and is a T-shaped piston of which the lower end is small and the upper end is large; a hole which is matched with a small diameter section of the piston II is formed in the arc-shaped plate; aninjection liquid cavity is formed between the piston I and the piston II; and a plurality of inner containing type superfine efflux microacupuncture needle tips are arranged on the piston II. According to the Pascal disposable subcutaneous intramuscular injector disclosed by the invention, the syringe needle is the inner containing type superfine efflux microacupuncture needle tips which are arranged in a certain distance; and medicaments are injected in muscles of a patient through the superfine efflux microacupuncture needle tips, and are absorbed in the muscles of the patient in a messingand dispersing manner (spreading and sinking manner), so that the pain is avoided, the diffusion is quick, and the absorption is good.

Description

technical field [0001] The invention relates to a disposable hypodermic intramuscular syringe, in particular to a Pascal disposable hypodermic intramuscular syringe. Background technique [0002] At present, commercially available disposable syringes are single-needle syringes with relatively large needles. Although this type of syringe is cheap and easy to use, the needle is thick and the patient feels a lot of pain, especially for those patients who are afraid of injections. In addition, the medicine injected by the single-needle syringe is in the shape of a water bag in the patient's muscle, with slow diffusion and poor absorption, and it is easy to form a lump in the patient's muscle. Therefore, it is a technical problem to be solved at present to design a Pascal disposable hypodermic intramuscular injector that is painless, diffuses quickly, and absorbs well. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide...

AI Technical Summary

Problems solved by technology

Although this kind of syringe is cheap and easy to use, but because of the thick needle, the patient feels obvious pain, especially for those patients who are afraid of injections, it is simply harmful

In addition, the drug injected by the single-needle syringe is in the shape of a water bag in the patient's muscle, which diffuses slowly and is poorly absorbed, and it is easy to form a lump in the patient's muscle
