Abstract

The filter syringe according to the present invention includes: a syringe formed with a coupling tube so as to be combined with an injection needle; a filter part provided inside the syringe and including a first path and a second path, the first a path for the injection liquid to flow into the barrel through the injection needle, the second path is formed in a central portion of the first path and allows the injection liquid to be discharged from the barrel to the outside; and the piston, the A connecting shaft member capable of being connected to the filter part is formed in front of the piston, and when at least a part of the piston is inserted into the barrel, the piston moves forward or backward to allow the injection liquid to flow into the syringe. inside the syringe or vent to the outside of the syringe, and the filter section includes.

Description

technical field [0001] The present invention relates to a filter syringe. Background technique [0002] Typically, syringes are used to collect blood from a patient's blood vessels or to collect bodily fluids other than blood within the body. Syringes, on the other hand, are used to inject drugs directly into blood vessels or inject drugs into muscles or subcutaneously, etc. [0003] That is, the syringe can be used to collect body fluids in the body or to inject injections into the body. [0004] On the other hand, when the injection solution is injected into the body through a syringe, in order to move the medicine contained in a glass ampoule or a small glass vial with a rubber stopper into the syringe, the upper end of the glass ampoule is cut off, and through the cut Part of the needle is inserted into the injection needle to inhale the drug to be injected. [0005] Cover the injection needle of the syringe thus used with the protective cap and discard it. At this t...
