Abstract

According to the present invention, a filter syringe includes: a cylinder including a combination pipe to be combined with a syringe needle; a filter part installed in the cylinder and including a first path to make injection liquid flow into the cylinder through the syringe needle, and a second path formed in the center of the first path to discharge the liquid from the cylinder; and a piston including a combination shaft formed in the front to be combined with the filter part, and injecting the injection liquid into the cylinder or discharging the liquid from the cylinder by moving forward or backward while having at least one part inserted into the cylinder. The filter part also includes other parts.

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...
