The specific meaning of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The utility model discloses a comfortable insulin pen needle, as shown in figure 1, including needle tubing 1 and needle file 2, it lies in different from prior art: the method is characterized in that: 2 departments of needle file form the needle tubing assembly base station 3 that is used for assembling

needle tubing

1, and 3 departments of needle tubing assembly base station are equipped with the pilot hole 4 that is used for assembling needle tubing 1, and needle tubing 1 runs through pilot hole 4 and distributes, form encapsulating chamber 5 between the cavity upper portion of pilot hole 4 and needle tubing 1, be equipped with glue 6 in the encapsulating chamber 5, glue 6's horizontal level is less than the level at 4 tops of pilot hole, perhaps, glue 6's horizontal level keeps unanimous with the level at 4 tops of pilot hole, and the annular shirt rim 7 is formed to the periphery of needle tubing assembly base station 3, and the lower edge of shirt rim 7 links into an integrated entity with needle file 2, and the last reason of shirt rim 7 forms hem 8.

In specific implementation, a folded edge 8 which is folded inwards is formed at the upper edge of the skirt edge 7, the folded edge 8 forms an annular folded edge, a large plane 14 with the diameter of 3mm-8mm is formed on a plane where the annular folded edge is located, a round corner part 9 is formed at the bending part of the folded edge 8, the curvature radius of the round corner part 9 is R, and R is more than 0 and less than or equal to 2.5 mm.
