Insulin pen needle for subcutaneous injection in diabetic patients with improved safety and usability, characterized in that the protruding block has a wide outer diameter, so that the contact area is wide when injecting drugs, reducing pain, and improving the grip feeling to hold the pen needle, enhancing usability. About.

In addition, the present invention prevents from rising above the fixing groove as the adhesive (epoxy) filled to fix the injection needle is cured (dried) while sinking by its own weight in the fixing groove. It is characterized in that it is possible to fundamentally remove the pain-causing factor (protruding pointed protrusions that contact the skin during drug injection, causing pain such as stabbing) due to drug injection.

In addition, the present invention allows the flange blade to protrude from the outer edge of the insertion hole of the small cap, and the flange blade corresponds to the opening of the hub so as to have a high degree of compression fitting, which is formed to block the external exposure of the injection needle in the hub. It is characterized in that it prevents the risk of puncture by the needle and the risk of safety accidents such as secondary infection.

In addition, the present invention greatly enhances the grip by forming a protrusion strip (protrusion line or protrusion body) on the outer circumferential surface of the hub, the small cap, and the large cap, respectively, as well as the protrusion strip (protrusion line or protrusion body) for assembly or post-processing. It is characterized in that it is formed to have a wide and low protruding surface when gripping (grabbing) to minimize grip pain in diabetic patients.

In general, a pen needle refers to a hub equipped with a needle (N), and is composed of a pen needle set including a small cap, a middle cap, and a sterilization finish.

7B is a cross-sectional view showing the shape of a conventional pen needle set, in which a needle N is mounted in the center of a hub, and a small cap is covered thereon.

And, the large cap is covered on the top of the small cap, and the sterilization finish is attached to the bottom of the hub and sealed.

On the other hand, when using a pen needle, remove the sterilization finish attached to the lower side of the hub, and fasten and connect the pen needle with the large cap and the small cap on the pen type syringe by screwing.

Thereafter, the large cap and small cap are sequentially removed and self-injection is performed.After use, the small cap or large cap is re-covered on the needle (N), and the screw direction is reversed from the pen-type syringe compared to the first time. It is formed to disassemble after being released and separated.

On the other hand, when the user wants to separate the pen needle from the pen-type syringe after using the pen needle, a process in which the user must cover the small cap or the large cap on the once used needle N is required.

At this time, the user does not put the small cap on the needle (N), but in the process of attempting to separate it immediately (or the process of rotating the hub by the screw loosening method), a safety accident such as being poked or scratched by the needle (N) exposed to the outside. The occurrence of bleeding and pain is frequently occurring.

In addition, as the diabetic patients become more severe, the fingertips are peeled off and rough and weak. Conventional pen needles are very small and cause great pain in the fingers due to the gripping and loss of sensation occurs.

That is, during self-treatment, there is a problem of missing or difficult to handle an injection kit provided for a single use, and there is a problem of being exposed to secondary infection accidents or secondary pain by being stabbed by a needle.

The object is to provide that pain is reduced and the sense of grip holding the pen needle is improved to enhance usability.

Accordingly, the present invention prevents the adhesive (epoxy) filled to fix the injection needle from rising above the fixing groove as it is cured (dried) while sinking by its own weight in the fixing groove. It is possible to provide a source of pain-causing elements (a raised pointed protrusion that contacts the skin during drug injection, causing pain such as a puncture) can be fundamentally eliminated.

In addition, the present invention allows the flange blade to protrude from the outer edge of the insertion hole of the small cap, and the flange blade corresponds to the opening of the hub so as to have a high degree of compression fitting, which is formed to block the external exposure of the injection needle in the hub. Its purpose is to provide to prevent the risk of safety accidents such as the risk of puncture by the needle and secondary infection.

In addition, the present invention greatly enhances the grip by forming a protrusion strip (protrusion line or protrusion body) on the outer circumferential surface of the hub, the small cap, and the large cap, respectively, as well as the protrusion strip (protrusion line or protrusion body) for assembly or post-processing. It is an object of the present invention to provide to minimize grip pain in diabetic patients by being formed to have a wide and low protruding surface when gripping (grabbing).

The present invention for achieving this purpose is to have an opening 120 formed at one end of the cup-shaped body 110, but the inner circumferential surface of the opening 120 side is screwed to correspond to the coupling tab 10 of the insulin pen 121 is formed, and a protruding block 140 having a support plate 130 is formed at the other end opposite to the opening 120, but at the center of the support plate 130, a needle corresponding to a vertical axis ( A hub 100 for bonding and fixing the adhesive (epoxy) while passing through the fixing groove 131; An insertion hole 220 is formed on one side of the cylindrical body 210 to be fitted while corresponding to the outer circumferential surface of the protruding block 140, but a space 230 is formed inside so that the injection needle 150 can be accommodated. , A flange wing 240 is formed on the outer rim of the insertion hole 220 so that when the injection is completed, the flange wing 240 is forcibly inserted toward the opening 120 of the hub to be compressed and fixed. and; A large cap 300 is formed so that the hub 100 to which the small cap 200 is coupled is formed in one side of the cone-shaped body; It is composed and made.

Accordingly, it is preferable that the protruding block 140 has a diameter of 2/3 to 4/5 compared to the diameter of the trunk 110 and has a large diameter shape for preventing pain.

In addition, it is preferable that the body 110 has a plurality of protrusion bands 111 for enhancing a sense of grip on the outer circumferential surface in the circumferential direction.

On the other hand, the sterilization paper 320 is initially attached to the opening of the hub among the small cap 200 and the hub 100 accommodated through the inner inlet groove 310 and is formed so as to be detached when used.

As described above, the present invention minimizes the induction of pain due to the handling of the pen needle for the diabetic patient during subcutaneous injection (all processes of opening, holding, attaching and detaching the pen needle to assemble the pen needle for the insulin pen). This has the effect of enhancing the usability as the protruding block of the hub has a wide outer diameter, so that the contact area is wide when the drug is injected, reducing pain, and improving the grip feeling to hold the pen needle.

In addition, the present invention prevents from rising above the fixing groove as the adhesive (epoxy) filled to fix the injection needle is cured (dried) while sinking by its own weight in the fixing groove. As it is possible, there is an effect that causes pain caused by drug injection (a raised pointed protrusion that contacts the skin during drug injection causes pain such as a puncture) can be eliminated at the source.

In addition, the present invention allows the flange blade to protrude from the outer edge of the insertion hole of the small cap, and the flange blade corresponds to the opening of the hub so as to have a high degree of compression fitting, which is formed to block the external exposure of the injection needle in the hub. It has the effect of preventing the risk of puncture caused by the needle and the risk of safety accidents such as secondary infection.

In addition, the present invention greatly enhances the grip by forming a protrusion strip (protrusion line or protrusion body) on the outer circumferential surface of the hub, the small cap, and the large cap, respectively, as well as the protrusion strip (protrusion line or protrusion body) for assembly or post-processing. When gripping (grabbing), it is formed to have a wide and low protruding surface, which has the effect of minimizing grip pain in diabetic patients.

Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

As shown in Figures 1 to 6, the present invention is largely composed of a hub 100, a small cap 200 and a large cap 300.

Accordingly, the hub 100 has an opening 120 formed at one end of the cup-shaped body 110, but the inner circumferential surface of the opening 120 side corresponds to the coupling tab 10 of the insulin pen and is screwed so as to be screwed ( 121) is formed.

In this case, a protruding block 140 having a support plate 130 is formed at the other end opposite to the opening 120.

Accordingly, the injection needle 150 corresponding to the vertical axis is formed in the central portion of the support plate 130 to be bonded and fixed by an adhesive (epoxy) while penetrating the fixing groove 131.

Accordingly, it is preferable that the protruding block 140 has a diameter of 2/3 to 4/5 compared to the diameter of the trunk 110 and has a large diameter shape for preventing pain.

In addition, it is preferable that the body 110 has a plurality of protrusion bands 111 for enhancing a sense of grip on the outer circumferential surface in the circumferential direction.

The protruding band has a low protruding height and a wide area extending to the side so that pain is not caused to the finger when gripping.

At this time, the adhesive (epoxy) that fixes the injection needle is filled so that it does not overflow from the fixing groove (half moon or water droplet shape), and after a certain period of time, the filled epoxy partially sinks and the adhesive does not protrude above the upper surface of the support plate.

This is to prevent pain by making sure that there is no surface rising on the plane.

On the other hand, the small cap 200 has an insertion hole 220 formed on one side of the cylindrical body 210 so that it is fitted while corresponding to the outer circumferential surface of the protruding block 140, so that the injection needle 150 can be accommodated therein. The space part 230 is formed.

At this time, the flange blades 240 are formed on the outer rim of the insertion hole 220 so that when the injection use is completed, the flange blades 240 are forcibly fitted toward the opening 120 of the hub to be compressed and fixed.

Accordingly, the space portion is fitted while facing the injection needle (one end of the needle penetrating the inner space of the hub), which blocks external exposure so that the finger is not pierced by the injection needle.

In addition, the diameter of the cylindrical body is slightly wider than the protruding block of the hub to increase the grip (prevents pain when pinched with a finger).

At this time, a protrusion line 250 is formed on the outer peripheral surface of the cylindrical body in the circumferential direction to further increase a sense of grip. The protruding line has a low protruding height and a wide area extending to the side so that pain is not caused to the finger when gripping.

In addition, the flange wing is formed to be compressed and fixed to the opening in the form of force-fitting in an elastic structure.

Accordingly, it is preferable that a locking jaw or a wedge-shaped interrupter is further formed in the opening to prevent separation or separation of the flange blade.

In addition, it is preferable that the flange blade is formed such that an inclined surface is formed on the entering side of the cross-sectional thickness, and a bent part is formed on the side corresponding to the outer side, and is formed so that it is almost difficult to separate other than damage once mounted, thereby preventing recycling.

On the other hand, the large cap 300 is formed such that the inner inlet groove 310 is formed on one side of the cone-shaped body so that the hub 100 to which the small cap 200 is coupled is embedded.

Accordingly, it is preferable that the large cap has a protrusion body 330 formed on the outer circumferential surface of the body in the circumferential direction to increase the grip cap.

These protrusions have a low protruding height and a wide area extending laterally so that pain is not caused to the fingers when gripping.

On the other hand, the sterilization paper 320 is first attached to the opening of the hub among the small cap 200 and the hub 100 accommodated through the inner inlet groove 310, and is formed to be detached when used.

The present invention is not limited to the specific preferred embodiments described above, and any person with ordinary knowledge in the technical field to which the design belongs without departing from the gist of the present invention claimed in the claims can implement various modifications Of course, such changes will fall within the scope of the claims description.
