As shown in FIGS. 3 to 6, the disposable safety filter syringe 100 having the filtering special resin capable of moving up and down according to the present invention,

A cylinder 104 having a space in its interior and formed with a syringe discharge portion 102 having a hole 101 at a front side thereof in a stepped state;

A plunger (106) fitted in the space in the cylinder and moving in the forward or backward direction;

And is provided on the front side of the plunger (106) to move in a hermetic contact with the inner surface of the cylinder (104) when moving the plunger (106) forward or backward to provide a suction force for sucking the liquid into the space in the cylinder A piston (108) for providing a compressing force for discharging the injection liquid accommodated in the space portion to the outside;

A first through hole 110 is formed at one side of the inner surface of the injection liquid discharging portion 102 so as to communicate with the hole 101 of the injection liquid discharging portion 102, The second through hole 600 provides the injection fluid path when the piston 108 provides a suction force and the second through hole 600 provides the injection fluid path to the inside of the ampule 600 along the second through hole 600. [ Or the injected liquid contained in the inside of the rubber stopper bottle is received in the space portion in the cylinder 104 and the injected liquid is filtered by the special resin 204 for filtering when the piston 108 provides the compressing force, To the hole (101) of the filter (112);

And an injection needle 114 fixed to the injection liquid discharge unit 102 on the outer surface to inject the injection liquid discharged from the hole 101 of the injection liquid discharge unit 102 to the patient.

7 to 9, the filter means 112 includes:

A first through hole 110 at the center and a second through hole 600 at a predetermined distance from the first through hole 110 to be inserted and fixed in the inner surface of the injection liquid discharging portion 102, (110) through the second through-hole (600) when the piston (108) provides a suction force, and when the piston (108) And the second through hole (600);

And is positioned between the inner surface of the fixed portion 202 and the inner surface of the injection liquid discharge portion 102. The piston 108 is fixed on one side and the piston 108 moves up and down when the piston 108 provides a compressive force, And a filtering special resin 204 for filtering the injection liquid contained in the space portion in the cylinder 104 and for supplying the filtered injection liquid to the through hole 110 of the fixing portion 202 when the compression liquid supply portion 108 provides the compression force.

Here, as shown in Fig. 13,

When the piston 108 provides the suction force, the filtering special resin 204 flows backward to provide the injection liquid passage so that the injection liquid accommodated in the inside of the ampoule or the rubber stopper bottle along the injection liquid passage passes through the second through- 600 to be accommodated in the space in the cylinder 104.

The assembling process and operation of the disposable safety filter syringe 100 having the filtering special resin capable of moving up and down according to the present invention constructed as described above will be described below.

Here, the assembling process of the disposable safety filter syringe 100 having the filtering special resin capable of moving up and down according to the present invention can be changed in any order depending on the assembler.

First, the injection liquid discharging portion 102 having the hole 101 is positioned in a stepped state.

After the filtering special resin 204 of the filter means 112 is positioned, the filtering special resin 204 is inserted and fixed to one side of the inner surface of the injection liquid discharging portion 102. After the fixing portion 202 having the first through hole 110 and the second through hole 600 of the filter means 112 is positioned and the fixing portion 202 is connected to the injection liquid discharge portion 102, As shown in Fig. At this time, one side of the filtering special resin 204 is fixed by the fixing portion 202.

After the pusher 106 is positioned, a piston (not shown) is provided on the front side of the pusher 106 to provide a suction force for sucking the injection solution into the space in the cylinder or to provide a compression force for discharging the injection solution contained in the space in the cylinder to the outside. (108).

Then, the piston 108 is pushed into the space in the cylinder 104, and the injection needle 114 is installed on the outer surface of the injection liquid discharging portion 12.

When assembling the disposable safety filter syringe 100 having the filtering special resin capable of moving up and down according to the present invention as described above,

After placing an ampoule (glass bottle) containing the injection liquid, the upper end of the ampoule is broken by hand. Here, when the top of the ampoule is broken by hand, the uppermost fine glass powder enters the inside of the ampoule.

10, a disposable safety filter syringe 100 having a filtering special resin capable of moving up and down according to the present invention is inserted into an ampoule 400 having an upper end broken, Backward.

When the plunger 106 is pulled backward, as shown in Fig. 12, the piston 108 moves backward and simultaneously generates a suction force.

12 to 13, when one side of the filtering special resin 204 of the filter means 112 is connected to the second through hole 600 of the fixing portion 202 (Flows). At this time, as the filtering special resin 204 flows backward, an injection liquid passage is formed, and the injection liquid stored in the ampule through the second through-hole 600 is received in the space portion of the cylinder 104.

When the injection liquid is received in the space portion in the cylinder 104 as described above, the injection needle 114 is inserted into the body part of the patient, and then the pusher 106 is pushed forward to inject the injection liquid into the patient.

When the pusher 106 is pushed forward, the piston 108 moves forward and at the same time generates compressive force.

When a compression force is generated by the piston 108, one side of the filtering special resin 204 which has flowed backward comes into contact with one side of the inner surface of the injection liquid discharging portion 102 as shown in FIG.

The injected liquid stored in the space of the cylinder 104 is injected into the filtering special resin 204 through the first through holes 110 and the second through holes 600 of the fixed portion 202 of the filter means 112 And is discharged into the hole 101 of the injection liquid discharge portion 102. [

Therefore, the injection solution in which the fine glass dust of the ampule (vial) is removed is administered to the patient.

Meanwhile, when the injection solution contained in the rubber stopper bottle 500 shown in FIG. 11 is administered to the patient, the disposable safety filter syringe 100 having the filtering special resin capable of moving up and down according to the present invention is inserted into the rubber stopper 502 The injection needle 114 is inserted. At this time, when the injection needle 114 is inserted into the rubber stopper 502, fine rubber powder of the rubber stopper 502 enters the injection needle 114.

Therefore, when the injection solution contained in the rubber stopper bottle 500 shown in Fig. 11 is administered to the patient in the above manner, the fine rubber powder is filtered by the filtering special resin 204 of the present invention.

The detailed description of the design is merely exemplary in nature and is used merely for the purpose of describing the present invention and not for limiting the scope of the present invention as defined in the appended claims or utility model registration claims. Therefore, those skilled in the art will appreciate that various modifications and equivalent embodiments are possible without departing from the scope of the present invention. Therefore, the true scope of technical protection of this invention should be determined by the technical idea of the appended utility model registration claim.
