Description
The present invention relates to a syringe.
In general, a syringe is used to collect blood from a patient's blood vessel or to collect other body fluids in the body. On the other hand, it is used to inject drugs directly into the blood vessels or to inject drugs into the muscles or subcutaneously.
That is, the syringe can be used to collect body fluids in the body or to inject injections into the body.
On the other hand, in order to transfer the drug contained in the glass ampoule or the small glass bottle containing the rubber stopper into the syringe when the injection is injected into the body through the syringe, the upper part of the glass ampoule is cut and the injection needle I will inhale the drug to be injected.
When inserting an injection solution into a body through a conventional syringe, fine glass particles or debris may be mixed with the injection solution into the syringe, though not to a large extent, and the fine glass particles and the injection solution may be injected into the body together.
When injecting such injection solution into a patient, fine glass particles are injected into the body together with the injection solution, which adversely affects the health of the patient.
In addition, the conventional syringe filters the glass particles of the ampoule by the filter when sucking the injection liquid, but the injecting process is troublesome because the injector should be placed after removing the filter with the ampoule glass particles when the injection is made to the patient.
In one embodiment of the present invention, when injecting an injection liquid into a syringe, the injector injector injects the injected liquid through a filter member without passing through a filter member, thereby facilitating the injection process and preventing injection of the glass particles into the patient. to provide.

At this time, a plurality of protrusions are formed on the inner circumferential surface of the filter holder, and a plurality of fitting grooves are formed on the outer circumferential surface of the first outer tube portion to correspond to the plurality of protrusions, Lt; / RTI >
The first check valve may include a disc-shaped disc portion disposed on a front portion of the filter body so as to closely contact the front surface of the filter body to selectively block the first discharge hole when the injection liquid is introduced or discharged, And a second suction hole formed on the first fluid path at a central portion of the disc portion and the first post portion. The first suction hole may be formed in the center of the disc portion and the first post portion.
At this time, the disc portion may be spaced rearwardly of the latching jaw, and a moving space may be formed between the latching jaw and the disc portion so that the disc can be separated from the first discharge hole.
At this time, the second fluid path may be formed in the outer circumferential portion of the first fluid path so that the first fluid path and the second fluid path do not overlap with each other.
At this time, the first discharge hole and the second discharge hole may extend in the circumferential direction and may be formed to surround at least a part of the third suction hole and the first suction hole, respectively.
In this case, the piston includes a piston body which is inserted into the cylinder and moves in one direction, a gasket coupled to the front end of the piston body and fitted to the inside of the cylinder, and a gasket which is located at the front end of the piston body, And a coupling member having an open coupling groove, wherein the gasket is coupled to the piston body.
At this time, the coupling portion is provided in the movement space, and is movable forward and backward in the movement space, and includes a support portion formed to allow the injection liquid to flow in and out, and a support portion extending rearward from the support portion, And may include an engagement shaft member.
