Abstract

The invention discloses a comfortable insulin pen needle with a fixing cap, wherein a needle tube assembling base station for assembling a needle tube is formed at a needle base, assembling holes for assembling the needle tube are formed at the needle tube assembling base station, the needle tube penetrates through the assembling holes to be distributed, a glue filling cavity is formed between the upper part of a cavity body of the assembling holes and the needle tube, glue is arranged in the glue filling cavity, the fixing cap is sleeved outside the needle tube assembling base station, the upper surface of the fixing cap forms a large plane, a round corner part is formed at the edge of the upper surface of the fixing cap, a through hole is formed at the upper surface of the fixing cap, and the upper end of the needle tube penetrates through the through hole upwards to. The contact area of the fixing cap is designed to be a large plane, and the edge of the large plane is designed to be a rounded arc angle, so that the touch of the contact area is further improved. 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 with fixing cap

Technical Field

The invention relates to the technical field of medical instruments, in particular to a comfortable insulin pen needle with a fixing cap, and particularly relates to a mechanical connection structure of the comfortable insulin pen needle.

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

The invention aims to provide a comfortable insulin pen needle with a fixing cap. The contact area of the fixing cap and the skin forms a large plane, and the edge of the fixing cap is designed into an arc angle, so that the touch feeling of the fixing cap in contact with the skin is effectively improved, and the defects in the prior art are overcome.

In order to achieve the purpose, the technical scheme of the invention is as follows: the utility model provides a comfortable type insulin pen needle with locking cap, includes needle tubing and needle file, needle file department forms the needle tubing assembly base station that is used for assembling the needle tubing, needle tubing assembly base station department is equipped with the pilot hole that is used for assembling the needle tubing, the needle tubing runs through the pilot hole and distributes, form the encapsulating chamber between the cavity upper portion of pilot hole and the needle tubing, be equipped with glue in the encapsulating chamber, a locking cap has been cup jointed to the outside of needle tubing assembly base station, locking cap upper surface forms big plane, the edge of locking cap upper surface forms fillet portion, the through-hole has been seted up to locking cap's upper surface department, the upper end of above-mentioned needle tubing upwards runs through the through-.

Further, the diameter of the large plane 8 is 3mm-8 mm.

Furthermore, the curvature radius of the round corner part 8 is R, and R is more than 0 and less than or equal to 2.5 mm.

The invention discloses a comfortable insulin pen needle with a fixing cap, which is characterized in that the contact area of the fixing cap is designed into a large plane, the edge of the large plane is designed into a round and smooth corner, and the touch feeling of the contact area is further improved. The injection is comfortable to contact, the pain of the patient is greatly reduced, and comfortable use experience is brought.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by a person skilled in the art based on the embodiments in the patent of the invention without any inventive work belong to the protection scope of the patent of the invention.

In the description of the present patent, it is to be noted that the terms "vertical", "upper", "lower", "horizontal", and the like indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience in describing the present patent and simplifying the description, but do not indicate or imply that the referred device or element must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present patent.

In the description of the present patent application, it is also noted that, unless otherwise explicitly specified or limited, the terms "disposed," "mounted," "connected," and "connected" are to be construed broadly and may, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meanings of the above terms in the present patent can be understood by those skilled in the art according to specific situations.

The invention discloses a comfortable insulin pen needle with a fixing cap, which comprises a needle tube 1 and a needle base 2 as shown in figure 1, and is different from the prior art in that: 2 departments of needle file form the needle tubing assembly base station 3 that is used for assembling

needle tubing

1, 3 departments of needle tubing assembly base station are equipped with the pilot hole 4 that is used for assembling needle tubing 1, needle tubing 1 runs through pilot hole 4 and distributes, form encapsulating chamber 5 between the cavity upper portion of pilot hole 4 and the needle tubing 1, be equipped with glue 6 in the encapsulating chamber 5, a locking cap 7 has been cup jointed to the outside of needle tubing assembly base station 3, locking cap 7 upper surface forms big plane 8, the edge of locking cap 7 upper surface forms fillet portion 8, through-hole 9 has been seted up to the upper surface department of locking cap 7, the ascending through-hole 9 that runs through in upper end of above-mentioned needle tubing 1 distributes. A larger contact plane is formed on the upper surface of the fixing cap 7, so that the comfortable feeling of contacting with the skin can be effectively improved.

In specific implementation, the horizontal section of the fixing cap 7 is circular, elliptical, rectangular or regular polygonal.

In specific implementation, the diameter of the large plane 8 is 3mm-8 mm.

In the specific implementation, the curvature radius of the round corner part 8 is R, and R is more than 0 and less than or equal to 2.5 mm.

The foregoing is a more detailed description of the present invention in connection with specific preferred embodiments thereof, and it is not intended that the invention be limited to the specific details set forth herein.
