Novel dual-head syringe

Abstract

The invention discloses a novel dual-head syringe comprising a needle cylinder (1) which contains a piston (2) therein; the piston (2) is connected with a piston shaft (3); the piston shaft (3) is provided with a piston handle (4); two nipples (5) are installed at a bottom of the needle cylinder (1); the nipples (5) sleeve on needle tips (6). The invention has following beneficial effects: the syringe has reasonable design and simple structure. When the novel dual-head syringe is being used, expected effects can be achieved; the piston can be well clung to the needle cylinder during injectionand it can be push in smoothly; the injection is quick and convenient.

Description

technical field [0001] The invention relates to the medical field, in particular to a novel double-head syringe. Background technique [0002] Syringes are a common medical appliance. As early as the 15th century, Italian Catinel proposed the principle of syringes. Syringes are also used in medical equipment, containers, and scientific instruments such as some chromatography to inject through a rubber septum. Injecting gas into a blood vessel can cause an air embolism. The way to remove air from the syringe to avoid embolism is to invert the syringe, tap it gently, and squeeze out a little fluid before injecting into the bloodstream. [0003] In some occasions where accuracy is not the primary consideration for germs, such as quantitative chemical analysis, glass syringes are still used because of their small errors and smooth push rod movement. [0004] You can also use a syringe to inject some of the juices into meat while cooking to improve flavor and texture, or into ...

AI Technical Summary

Problems solved by technology

In medical use, there may also be a series of problems caused by slow injection advancement, high resistance, and insufficient sealing of the piston.
