RESTRAINER OF EDGE PART OF INJECTION NEEDLE

摘要

A restrainer of edge part of injection needle comprising support piece with finger pad is claimed. The support portion is formed as a disc. One plane of abutment is a finger pad, and on the opposite from the center plane the spiral extends perpendicularly with the corresponding parameters of the thickness of the injection needle and the inner diameter of the spiral and helical spaces between the curls. The curls provide conditions for winding of the retainer to the tapered portion of the needle bent under angle of 90 °.
