Abstract

The utility model discloses a comfortable type insulin pen needle, needle file department forms the needle tubing assembly base station department that is used for assembling the needle tubing and is equipped with the pilot hole that is used for assembling the needle tubing, and the needle tubing runs through the pilot hole and distributes, forms the encapsulating chamber between the cavity upper portion of pilot hole and the needle tubing, and the encapsulating intracavity is equipped with glue, and the horizontal liquid level of glue is less than the horizontal position on pilot hole upper portion, perhaps, the horizontal liquid level of glue keeps unanimous with the horizontal position on pilot hole upper portion, and the upper surface of needle tubing assembly base station forms big plane, and the edge of needle tubing assembly base station forms fillet portion. The contact area of the needle tube assembly base station is designed into a large plane, the edge of the large plane is designed into a round and smooth arc angle, in order to further improve the touch feeling of the contact area, the liquid level of the glue is controlled in the glue filling area, and the skin of the contact area is prevented from being irritated by the protruded glue. The injection is comfortable to contact, the pain of the patient is greatly reduced, and comfortable use experience is brought.

Description

Comfortable insulin pen needle

Technical Field

The utility model belongs to the technical field of medical instrument's technique and specifically relates to a comfortable type insulin pen needle, its mechanical connection structure of in particular to.

Background

Insulin pen needle on the existing market, needle tubing and needle file junction all are the facet, and the corner is sharp, and connects with the glue protrusion, pastes tight skin when clinical injection, leads to the painful sense of contact area to strengthen, brings the injection misery for the patient. Therefore, there is still a need for further improvement of the structure of the existing insulin pen needle to improve the contact feeling with the skin contact area.

Disclosure of Invention

An object of the utility model is to provide a comfortable type insulin pen needle. The large plane is formed in the contact area of the needle tube and the skin, the edge of the needle tube assembly base station is designed into an arc angle, the touch feeling of the needle tube assembly base station contacting the skin is effectively improved, and the defects in the prior art are overcome.

In order to realize the purpose, the technical scheme of the utility model is that: the utility model provides a comfortable type insulin pen needle, includes needle tubing and needle file, needle file department forms the needle tubing assembly base station that is used for assembling the needle tubing, and needle tubing assembly base station department is equipped with the pilot hole that is used for assembling the needle tubing, and the needle tubing runs through the pilot hole and distributes, forms the encapsulating chamber between the cavity upper portion of pilot hole and the needle tubing, is equipped with glue in the encapsulating chamber, and the horizontal liquid level of glue is less than the horizontal position on pilot hole upper portion, perhaps, the horizontal liquid level of glue keeps the unanimity with the horizontal position on pilot hole upper portion, and the upper surface of needle tubing assembly base station forms big plane, and the edge of needle tubing assembly base station forms fillet portion.

Furthermore, the horizontal section of the needle tube assembling base station is circular, elliptical, rectangular or regular polygonal.

Furthermore, the curvature radius of the round corner is R, and R is more than 0 and less than or equal to 2.5 mm.

The utility model discloses a comfortable type insulin pen needle, its area of contact with needle tubing assembly base station designs into big plane to design into mellow and full arc angle with its big plane edge, for further improving the sense of touch of contact zone, still with the liquid level control of glue inside the encapsulating district, avoid the excitement sense of convex glue to the contact zone skin. The injection is comfortable to contact, the pain of the patient is greatly reduced, and comfortable use experience is brought.
