Safety syringes for insulin administration {Safety syringes for insulin medicament}

The present invention relates to a safety syringe for administering insulin, and more particularly, after administering an insulin injection solution, when the pressing action of the depressed syringe plunger is released, the needle blocking body is lowered toward the syringe needle receptacle and automatically removes the injection needle. The present invention relates to a safety syringe for insulin administration, which prevents reuse by blocking exposure of the injection needle to the outside as well as preventing infection accidents due to reuse of the injection needle in advance.

In general, a syringe for administering insulin includes a syringe barrel having a receiving part for accommodating insulin liquid therein, an injection needle provided at the tip of the syringe barrel and inserted into the patient's skin, and the insulin liquid accommodated inside the syringe barrel through the injection needle. It is provided with a syringe plunger to be injected into the patient's skin, and in a state where the injection needle is inserted into the patient's skin, the syringe plunger is pressed toward the injection needle so that the insulin solution is administered.

However, once used injection needles must be discarded to prevent reuse of needles, which leaves bloodstains from the patient on the used injection needles, and if the needles with bloodstains are used again, they are included in the bloodstains left on the needles This is because the pathogens that have been infected are transferred to other people as they are, and secondary infection accidents occur due to the transferred pathogens.

In addition, in some cases, in order to reduce the purchase cost, used syringes are reused without discarding, which causes infection due to the spread of diseases as well as social problems due to infection.

Accordingly, there is an urgent need for technology development to prevent reuse of insulin injection needles after being used once.

As a prior art, a syringe needle reusability prevention cap, Registered Patent No. 10-1940085, has been devised, which has a plurality of gripping protrusions on the outer surface, a connection flange at the bottom, and a cap in which the injection needle body provided with the injection needle is stored inside. A needle reusability prevention cap composed of a body and a blocker covering and blocking the upper end of the cap body, wherein the cap body comprises: an upper flange, a needle accommodating portion in which the needle is positioned and accommodated, and upward from the needle accommodating portion. An expansion part extending toward the upper flange, an blocking body receiving part extending upward from the expansion part and having a blocking body fixing groove on an inner surface, and the needle receiving part positioned between the needle receiving part and the expansion part. The gripping protrusion of the needle body accommodated in is provided with a receiving and fixing groove portion that is accommodated and fixed, and the blocking member includes a blocking portion inserted inside the upper flange to block the upper flange, and a first blocking portion extending from the blocking portion. A first elastic fixing part cut by the incision and inserted into and fixed to the blocking body fixing groove, and extending from the blocking part to be positioned inside the first elastic fixing part and cut by the second incision and the needle accommodating part It is provided with a second elastic fixing portion to which the connecting flange of the injection needle body accommodated in is engaged.

In the present invention made as described above, the used injection needle is separated from the syringe tip after injection, stored and discarded, but the stored injection needle is prevented from being separated from the cap body, so that the reuse of the once used injection needle can be prevented. making it possible

However, in the case of the prior art, when the blocking body is forcibly separated or cut from the cap body, there is a problem in that the needle is exposed and the needle can be taken out of the cap body.

Hereinafter, a safety syringe for insulin administration according to an embodiment of the present invention will be described in more detail with reference to the accompanying drawings.

As shown, the present invention is a syringe barrel 10 filled with insulin injection solution and having a needle receiving port 11 at the bottom, and a syringe needle accommodated in the needle receiving port 11 of the syringe barrel 10. 20, and a syringe plunger provided inside the syringe barrel 10 and supplying the insulin injection solution filled in the syringe barrel 10 to the side of the injection needle 20 by a pressing operation so that the insulin injection solution is administered ( 30), and when the pressing operation of the syringe plunger 30 is released, it descends toward the injection needle 20 and covers the injection needle 20 to block exposure of the injection needle 20 to the outside. ) to a safety syringe made of

In the present invention, when the injection needle 20 is exposed when the insulin injection solution is administered, the insulin injection solution is administered, and after the insulin injection solution is completely administered, when the pressing operation of the syringe plunger 30 is released, the needle blocking body 100 ) Since the exposure of the injection needle 20 is blocked and locked so that the injection needle 20 is no longer exposed, reuse of a once-used syringe can be reliably prevented.

Accordingly, since the exposure of the injection needle is no longer made, the injection needle of the once-used syringe cannot be reused as the exposure of the injection needle is completely blocked, thereby preventing secondary infection due to reuse of the syringe.

To this end, the injection needle blocking body 100 of the present invention is fitted to the lower end of the syringe barrel 10 and covers and protects the outside of the injection needle receiver 11. Provided on the outside of the former housing 110 to cover and protect the outside of the shut-off housing 110, and a sterilization cap connector 110a into which the sterilization cap 1 is inserted, and provided inside the shut-off housing 110 However, the needle blocking device 120 surrounding the needle receiving device 11 and the guide device positioned at the inner upper end of the blocking device housing 110 and inserted into the outer upper end of the needle blocking device 120 ( 130), and an elastic spring 140 fitted to the outer surface of the needle holder 11 and accommodated in the blocker housing 110.

In addition, the lower end of the elastic spring 140 is closely supported inside the needle blocking hole 120 and compressed while being pressed by the needle blocking hole 120 when the insulin injection solution is administered, and then the syringe after administering the insulin injection solution. When the pressing operation of the plunger 30 is released, the needle blocking hole 120 is quickly lowered while the compression is released so that the exposed injection needle 20 is covered and blocked by the needle blocking hole 120 .

The blocker housing 110 has an upper end inserted into and fixed to the lower end of the syringe barrel 10, and covers and protects the outside of the injection needle receiver 11 accommodating the injection needle 20.

In addition, the lower end of the close guide 130 is in close contact with the upper end of the needle cut off 20 while being inserted into the outer upper end of the needle cut off 120.

Accordingly, when the needle blocker 120 is drawn into the blocker housing 110 side, it is drawn into the blocker housing 110 side like the needle blocker 120.

In the present invention made as described above, when the insulin injection solution is administered, the injection needle 20 is exposed from the blocker housing 110 and the needle blocker 120 and inserted into the skin, as shown in FIG. At this time, the insulin injection solution accommodated in the syringe barrel 10 is administered through the injection needle 20 inserted into the skin while the syringe plunger 30 is pressed, and the elastic spring 140 is compressed.

In addition, when the insulin injection solution is completely administered, as shown in FIG. 7, the needle blocking hole 120, which has been drawn into the inside of the blocking hole housing 110, quickly descends toward the injection needle 20, and the injection needle 20 By covering the outside of the injection needle 20 to block exposure, which means that the elastic spring 140, which has been compressed while the needle blocking hole 120 is drawn into the blocking device housing 110, blocks the needle from the skin surface. As the lower end of the sphere 120 is separated and the pressing action of the elastic spring 140 is released, the needle blocking device 120 quickly moves from the blocking device housing 110 by the restoring force of the compressed elastic spring 140. It is lowered and drawn out to cover and block the injection needle (20).

Accordingly, as shown in FIG. 3, in a state where the lower end of the needle blocker 120 is in close contact with the skin surface to administer the insulin injection solution, the syringe barrel 10 is pushed toward the skin surface and the syringe plunger ( 30), as shown in FIGS. 4 and 5, the needle blocker 120 is drawn into the blocker housing 110, and at this time, the lower end is in close contact with the spring contact jaw 122. The supported elastic spring 140 is compressed while being pressed by an operation in which the needle blocker 120 is drawn into the blocker housing 110.

In addition, when the injection needle 20 is removed from the skin after the insulin injection solution is completely administered and the contact between the needle blocking device 120 and the skin surface is released, the pressing force of the compressed elastic spring 140 is released. while the elastic spring 140 is restored, and accordingly, the spring contact jaw 122, which is closely supported by the lower end of the elastic spring 140, is pushed, and the needle blocker 120 provided with the spring contact jaw 122 ) is rapidly descended and drawn out from the blocker housing 110 to cover and block the injection needle 20.

In this way, when the needle blocker 120 is withdrawn from the blocker housing 110 by the restoring force of the elastic spring 140 and covers the injection needle 20, the drawn out needle blocker 120 is removed from the blocker housing ( 110), the withdrawn state of the needle blocking device 120 is fixed so that the needle blocking device 120 is no longer retracted into the blocking device housing 110, and the needle 20 is no longer inserted into the blocking device housing 110. It is not exposed to prevent reuse of once used syringes.

To this end, a locking protrusion 123 is provided on the outer surface of the needle blocking device 120 of the present invention.

In addition, an elastic locking piece 111 is provided with one side connected to the inner surface of the blocker housing 110 in a cut state with respect to the inner surface of the blocker housing 110 .

Accordingly, after the needle blocking device 120 is brought into close contact with the skin surface to administer the insulin injection solution, the needle blocking device 120 is operated by pushing the syringe barrel 10 and the syringe plunger 30 toward the skin. When the syringe barrel 10 is pushed up, the elastic locking piece 111 is in close contact with the close guide 130 and spreads, so that the needle blocker 120 interferes with being drawn into the blocker housing 110. do not receive

In addition, after all the insulin injection solution is administered, the pressing action of the syringe plunger 30 is released, and the injection needle 20 inserted into the skin is pulled out from the skin to separate the syringe barrel 10 from the skin, and the compressed elastic spring ( When the needle blocking device 120 rapidly descends by the restoring force of 140) and covers and blocks the exposed injection needle 20, the opening of the elastic locking piece 111 is released, and the needle blocking device 120 is locked. Since the elastic locking piece 111 is located at the upper end of the protrusion 123 and is caught in close contact with the upper end of the locking protrusion 123, the needle blocking part 120 is prevented from being pushed up toward the syringe barrel 10 again.

At the lower end of the sterilization cap connector (110a) of the present invention, when the needle blocker 120 is rapidly lowered by the restoring force of the elastic spring 140, the needle blocker toward the lower side of the blocker housing 110 ( 120) is provided with a break-away prevention protrusion 112 that is closely attached to the lower end of the locking protrusion 123 of the needle blocking sphere 120 to prevent it from coming out completely.

As the departure prevention protrusion 112 is provided as described above, the needle blocking device 120 is quickly lowered by the restoring force of the elastic spring 140, and the needle blocking device 120 moves toward the lower side of the blocking device housing 110. When is withdrawn, since the lower end of the locking protrusion 123 of the needle blocking device 120 is caught on the upper end of the detachment prevention protrusion 112, the withdrawal length of the needle blocking device 120 is interfered with, and thus the needle blocking device (120) is completely removed from the sterile cap connector (110a) to prevent exposure of the injection needle (20) to be blocked.

A first locking protrusion 113 is provided on the bottom inner surface of the syringe barrel 10 of the present invention, and a second locking protrusion 114 is provided on the outer surface of the blocker housing 110.

Accordingly, the second locking protrusion 114 is elastically fitted into the first locking protrusion 113 by the operation of pushing the blocker housing 110 toward the inside of the lower end of the syringe barrel 10, and the second locking protrusion 114 is hooked and fixed. , The syringe barrel 10 and the blocker housing 110 can be firmly fixed, so that when the syringe barrel 10 is pressed toward the skin to administer the insulin injection solution, the blocker housing 110 is pressed toward the skin together. This is possible, so that the needle blocker 120 is easily drawn into the blocker housing 110.

In addition, on the inner surface of the blocker housing 110, when the needle blocker 120 is pushed up toward the syringe barrel 10, the lower end of the close guide 130 is supported by a guide support protrusion 115 is provided

Accordingly, when the elastic spring 140 is withdrawn from the blocker housing 110 while the needle blocker 120 is lowered by the restoring force to cover and block the injection needle 20, the close guide 130 guides the guide support. As it is positioned in a state caught on the protrusion 115, the descending operation of the close contact guide 130 is prevented.
