As shown in figure 1, the insulin pen needle is provided with a needle 12 at the front end and a needle cap 10 at the rear end, a needle base 11 is arranged on the needle cap 10 towards the extending direction of the needle 12, a groove is arranged on the outer surface of the needle cap 10, and the needle 12 is integrally fixed on the needle cap 10.

The embodiment of the insulin pen needle detaching device is shown in figure 2, and is in a long strip shape, the front end is a detaching cap 20, the middle is a handheld part 22, and the rear end of the handheld part 22 is provided with a base 26. The handheld portion 22 is rod-shaped and made of silica gel, is streamlined and integrally designed, is comfortable in hand feeling, and is beneficial to rotating the dismounting device anticlockwise, so that the insulin pen needle 12 is dismounted.

Furthermore, the base 26 in this embodiment further has a suction cup (not shown in the drawings), which can be firmly attached to the smooth surface, such as a treatment cart or a treatment panel, for carrying; and can be stored vertically to avoid inclination.

Dismantle cap 20 and be hollow structure, its inner wall length is greater than the length of insulin pen syringe needle, through be equipped with on its inner wall with insulin pen syringe needle cap 10 coupled coupling portion 21 for insulin pen syringe needle cap 10 block is dismantling cap 20 inner wall, and rotatory dismounting device of anticlockwise can just dismantle insulin pen syringe needle 12 again.

Specifically, in the present embodiment, the detachable cap 20 is made of a plastic material, preferably a transparent plastic. The front end of its inner wall is cylindrical, to the recess on insulin pen needle cap 10, correspondingly, is equipped with the corresponding sand grip 21a with the recess of needle cap 10 on dismantling the cap 20 inner wall, and sand grip 21a is equipped with a plurality ofly, sets up along dismantling cap 20 inner wall circumference interval. The coupling portion 21 is formed on the cylindrical inner wall of the removal cap 20. It will be readily understood that the outer surface of insulin pen needle cap 10 may also be provided with ribs and, correspondingly, the inner wall of removable cap 20 is provided with grooves.

In order to prevent the insulin pen needle 12 from tilting or sliding rapidly when the insulin pen needle cap 10 is engaged, which causes the insulin pen needle 12 to pierce the detachable cap 20, a needle receiving portion 23 is further provided at one end of the inner wall of the detachable cap 20 close to the handle portion 22. Insulin pen needle 12 penetrates into needle housing 23 so that insulin pen needle 12 does not penetrate the inner wall of removal cap 20 and injure the hand. Preferably, the length of the needle housing 23 is greater than the length of the insulin pen needle 12.

Furthermore, a strip-shaped groove 24 can be formed in the needle containing part 23 towards the opening side of the detachable cap 20, and the groove 24 extends along the radial direction of the needle containing part 23, so that the insulin pen needle seat 11 can be clamped in the groove 24, and the stability and the operability of the insulin pen needle 12 during clamping are improved. It is clear that the recess 24 can also be replaced by a centrally arranged recess in the needle receptacle 23.

Further, a stop 25 is connected between the detachable cap 20 and the handle 22 to further ensure that the insulin pen needle 12 does not stick to the fingers holding the handle 22. The shape of the umbrella-shaped handle is similar to that of an umbrella opened towards the handheld part 22 and is made of silica gel. Preferably, the barrier 25 is integrally formed with the handle 22 for enhanced aesthetics. Of course, the barrier portion 25 may have another shape, preferably a sheet shape, and extends outward from the center of the barrier portion 25, thereby widening the barrier range. The barrier 25 and the handle 22 may also be removably connected so that the barrier 25 may be replaced.

The detachable cap 20 may be a cylinder, or the rear end of the detachable cap 20 may be gradually inclined and gathered, so that a gap exists between the rear end of the detachable cap 20 and the blocking portion 25, and when the insulin pen needle 12 pierces the detachable cap 20, the gap can be clearly seen, thereby preventing fingers from being further pierced.

When the rear end of the detachable cap 20 is a bevel structure, the shape of the needle accommodating portion 23 can be adapted to the shape of the rear end of the detachable cap 20, and the rear end of the detachable cap 20 is filled with the needle; or may still be a section of cylinder disposed at the rear end of the coupling portion 21.

The insulin pen needle dismounting device of the embodiment comprises the following use methods: insulin pen is after the hypodermic injection operation finishes, holds the handheld portion 22 in the dismounting device, then will dismantle the used needle cap 10 back on cap 20 alignment, the screens insulin pen, and manual anticlockwise rotation handheld portion 22 can dismantle the separation with the syringe needle rotation through dismantling cap 20.

The above embodiments are provided to illustrate, reproduce and deduce the technical solutions of the present invention, and to fully describe the technical solutions, the objects and the effects of the present invention, so as to make the public more thoroughly and comprehensively understand the disclosure of the present invention, and not to limit the protection scope of the present invention.
