Problems solved by technology

However, resin needles for blood vessels that have been proposed so far by the present applicant mainly have a structure in which a piston tube that is an inner body is slidably inserted into a barrel that is an outer body, and thus a solution (blood or aqueous solution) is injected Infiltration into the gap between the piston tube and the barrel, or possible backflow of blood in the blood vessel
Meanwhile, a conventional resin needle has a structure in which the barrel tube and the piston tube are connected using a membrane tube formed of a thin film material in order to prevent blood or aqueous solution from leaking and to prevent impurities from infiltrating from the outside; however, such a resin needle has a complicated structure and thus difficult to manufacture
In particular, a diaphragm formed of a thin film is easily damaged because it is exposed to the outside, and serious medical accidents may occur if the operator does not recognize the damage of the diaphragm

Abstract

The present invention relates to a reversible disposable sujichim (hand acupuncture) for blood vessels. The reversible disposable sujichim for blood vessels of the present invention is decreased in the total length compared with conventional sujichims while preventing exposure to the outside of a cylinder tube which forms the outer container when a piston tube consisting of a metallic needle is pushed back, and thus can reduce manufacturing costs and improve the convenience of storage, distribution, and handling.

Description

technical field [0001] The present invention relates to a resin needle for blood vessels comprising a resin tube and a metal needle for injecting blood or an injectable solution, such as an aqueous solution, into a blood vessel, and more particularly, for blood vessels Reversible and disposable resin needles, which reduce the overall length compared with conventional resin needles, while preventing a piston tube made of a metal needle from being exposed to an external container when it is pushed back, and thus can reduce manufacturing costs and improve Ease of storage, distribution and handling. Background technique [0002] A resin needle for blood vessels, which is generally configured to use a metal needle to achieve injection into the blood vessel, the metal needle is inserted into the resin tube, and the front edge partially protrudes, and then the metal needle is separated from the resin tube and the fluid tube is connected to the resin tube to Provide blood or aqueou...
