Summary of the invention

Technical problem to be solved by this invention is: provide a kind of injection needle point reducing pain.

For achieving the above object, the technical solution used in the present invention is: a kind of injection needle point, comprise: needle point main part and be arranged at the first tangent plane of needle point main part head, second tangent plane and the 3rd tangent plane, the central authorities of described needle point main part are provided with the mesopore that the centrage along needle point main part extends, described first tangent plane and the second tangent plane crossing formation first meld line, described first tangent plane and the 3rd tangent plane crossing formation second meld line, arrange in acute angle between described second tangent plane and the 3rd tangent plane, described second tangent plane collects formation needle point mutually with the 3rd tangent plane, described first tangent plane is that plane is arranged, described second tangent plane and the 3rd tangent plane are all arranged in arc surface, described second tangent plane and all recessed centrage to needle point main part of the 3rd tangent plane are arranged, described second tangent plane is provided with the first sandblasting layer, described 3rd tangent plane is provided with the second sandblasting layer.

Preferably, in above-mentioned a kind of injection needle point, the area of described first sandblasting layer is 2/3 of the second cross section area.

Preferably, in above-mentioned a kind of injection needle point, described first sandblasting layer is arranged near the top of the second tangent plane.

Preferably, in above-mentioned a kind of injection needle point, the area of described second sandblasting layer is 2/3 of the 3rd cross section area.

Preferably, in above-mentioned a kind of injection needle point, described second sandblasting layer is arranged near the top of the 3rd tangent plane.

Preferably, in above-mentioned a kind of injection needle point, arrange in 85 degree of angles between described first tangent plane and the second tangent plane.

Preferably, in above-mentioned a kind of injection needle point, the equal indentation of cross section of described first sandblasting layer and the second sandblasting layer is arranged.

Beneficial effect of the present invention is: in the injection in the present invention, needle point by being equipped with sandblasting layer on the second tangent plane and the 3rd tangent plane, insert in the process of human body the frictional force that can reduce between needle point and skin histology at needle point, thus the pain of patient can be reduced.

Accompanying drawing explanation

In order to be illustrated more clearly in the embodiment of the present application or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
