Abstract
The utility model relates to a needle head of a puncture needle, a first sharp needle face is arranged at the front end of the needle head of the puncture head, an inclination degree alpha of the first sharp needle face is 10 degrees to 15 degrees, second sharp needle faces are symmetrically arranged at two sides of the front portion of the first sharp needle face respectively, and the inclination degree beta of each second sharp needle face is 18 degrees to 25 degrees. The first sharp needle face and the second sharp needle faces are arranged at the front end of the needle head, a puncture needle is formed, wherein the puncture needle is smooth, the area of the tip of the needle head is small, the needle head of the puncture need is low in puncturing resistance, can not damage blood vessels, is safer in puncturing and enables a user to feel more comfortable.
Description
Technical field
This utility model relates to a kind of area of medical devices, particularly a kind of puncture needle syringe needle.
Background technology
Now, venous transfusion is very general clinically, mainly is patient and doctor's theory, thinks that venous transfusion can treat disease faster.In the human vein infusion process, need to use the needle point puncture vessel, and resistance is arranged in the needle point piercing process, the more big misery that causes to patient of resistance is more big, and in addition, the needle point cutting edge is rough, in piercing process, can damage blood vessel, damages to patient easily.
Summary of the invention
Technical problem to be solved in the utility model is at the deficiencies in the prior art, provides a kind of reasonable in design, easy to use, the puncture needle syringe needle that penetration Resistance is low.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of puncture needle syringe needle, be characterized in: the front end at the puncture needle syringe needle is provided with the first pin sword face, the gradient α of the first pin sword face is 10-15 °, the portion both sides are arranged with the second pin sword face respectively in face of the first pin sword, and the gradient β of the second pin sword face is 18-25 °.
Technical problem to be solved in the utility model can also further realize that the described second pin sword face is by forming ± 30 °-± 40 ° cuttings of syringe needle rotation by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the gradient α of the first pin sword face is 12 ° by following technical scheme.
Technical problem to be solved in the utility model can also further realize that the gradient β of the second pin sword face is 20 ° by following technical scheme.
This utility model is by being provided with the first pin sword face and the second pin sword face at the needle point front end, form the little puncture needle of head end area smooth, needle point like this, compared with prior art, its penetration Resistance is low, can not damage blood vessel, make needle point puncture safer, feel more comfortable.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is the postrotational structural representation of syringe needle.
The specific embodiment
Following with reference to accompanying drawing, further describe concrete technical scheme of the present utility model, so that those skilled in the art understands the present invention further, and do not constitute the restriction to its right.
See figures.1.and.2, a kind of puncture needle syringe needle, front end at puncture needle syringe needle 1 is provided with the first pin sword face 2, the gradient α of the first pin sword face 2 is 10-15 °, be preferably 12 °, the gradient β that is arranged with the second pin sword face, 3, the second pin sword faces 3 in the first pin sword face, 2 front part sides respectively is 18-25 °, is preferably 20 °.The described second pin sword face 3 is by forming ± 30 °-± 40 ° cuttings of syringe needle rotation.
During making, the front end inclined cut at syringe needle goes out the first pin sword face 2 earlier, and gradient α determines along with the needle tubing diameter variation.Again with syringe needle along needle axis to a sideway swivel 30 °-40 °, cut out the second pin sword face 3 of a side according to gradient β, after with the opposite side direction rotation of syringe needle to symmetry, repeat aforesaid operations then, can obtain required syringe needle.The first pin sword face 2 and the second pin sword face 3 want sandblast to polish smooth, and use on the hour hands and can smear medical silicone oil.
