Abstract

The utility model provides a syringe needle with a five-arris blade. An automatic edge grinding machine is made of the existing syringe needle; the needle point of the fabricated syringe needle is provided with a blade in five-arris shape; two blades of the top end of the syringe needle point are in symmetrical solid shape; the keen degree of the needle point is enhanced compared with the original syringe needle with three-arris blade. The bounce resistance of the muscle can be reduced when the syringe needle is injected, the puncturing of the syringe needle is fast, and the pain of the patient can be reduced.

Description

Syringe needle with five-arris blade

This utility model relates to a kind of five rib cutting edge entry needles, belongs to area of medical devices.

Present used entry needle when health care is injected various medicinal liquids etc., its needle point is plane rhizoma sparganic cutting edge, all adopts traditional first sharpening plane during fabrication, be generally 12 ° of inclination angles, use identical angle rolling needle tubing then, fall the left and right two sides basil, form plane rhizoma sparganic cutting edge.When adopting above-mentioned entry needle to do injection such as muscle, Intradermal, stronger pain is arranged to patient.

For overcoming the shortcoming of above-mentioned entry needle, the purpose of this utility model is to provide a kind of needle point more sharp, and inserting needle is easy, five rib cutting edge entry needles of pain in the time of reducing injection.

This utility model adopts the entry needle manufacturing with the grinding machine that puts the first edge on a knife or a pair of scissors, after finish at sharpening entry needle first inclination angle, by electric control reversing valve and pneumatic element, make the and arranged on left and right sides at needle tubing displacement and automatic sharpening second inclination angle, and then displacement automatically, two sides about sharpening the 3rd inclination angle are symmetrical stereo structure cutting edge thereby sharpening goes out the tip, form five rib cutting edge entry needles.Because five rib cutting edge entry needle needle points improve than traditional rhizoma sparganic cutting edge entry needle sharpness, when needle point enters muscle and subcutaneous tissue when injection, the effect that can produce the layering separating muscle, the bounce-back resistance of minimizing human body, can accelerate the inserting needle time, alleviate patient's pain greatly.

Below in conjunction with drawings and Examples, this utility model is described in further detail.

Accompanying drawing: five rib cutting edge entry needle needle point sketch maps

Present embodiment adopts the manufacturing of normal injection pin with the grinding machine that puts the first edge on a knife or a pair of scissors, and anchor clamps are by electric control reversing valve and pneumatic element control, automatic two kinds of angles of conversion.At first the angle modulation mainboard being regulated the inclination angle is 11 °-17 °, then the stainless pin pipe clamp of arranging is lived, (accompanying drawing (1)) was by electric control reversing valve and pneumatic element after finished at sharpening first inclination angle, promote clamping plate and turn forward 3 °-6 °, make the needle tubing displacement again, and the left side at automatic sharpening second inclination angle, right two sides (accompanying drawing (2), (3)), and then automatically 1 °-3 ° of displacements, the left and right sides at sharpening the 3rd inclination angle (accompanying drawing (4), (5)), thereby sharpening goes out five rib cutting edge entry needles, the digonous symmetrical stereo structure (Fig. 1, (4), (5)) that is in needle point top.

Claims

1, a kind of pumping needle is made up of needle tubing, needle stand, it is characterized in that: the injection needle point is five prismatic cutting edges (Fig. 1), and the entry needle pointed tip (Fig. 1, (4). (5)) two cutting edges are symmetrical stereo structure.
