Abstract
The invention discloses a comfortable large-plane insulin pen needle, wherein a glue filling cavity is formed between the upper part of a cavity of an assembly hole and a needle tube, glue is arranged in the glue filling cavity, the horizontal liquid level of the glue is lower than the horizontal position of the top of the assembly hole, or the horizontal liquid level of the glue is consistent with the horizontal position of the top of the assembly hole, an inward or outward folded edge is formed at the edge of the top of a needle tube assembly base station, the upper surface of the folded edge is a circular arc surface or a plane, the edge of the top of the needle tube assembly base station is designed into an outward folded edge, a large annular contact surface is further formed, a large and comfortable skin contact surface is provided, 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 irritation of the contact area caused by the protruded glue is avoided. The injection is comfortable to contact, the pain of the patient is greatly reduced, and comfortable use experience is brought.
Description
Technical Field
The invention relates to the technical field of medical instruments, in particular to a comfortable large-plane insulin pen needle, and particularly relates to a mechanical connection structure of the comfortable large-plane 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 large plane insulin pen needle. The needle tube assembly base station and the needle tube assembly base station form a large plane with a skin contact area, the edge of the needle tube assembly base station is designed into an edge which is turned outwards, an effective large contact surface is formed, the touch feeling of the needle tube assembly base station and 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: comfortable type insulin pen needle, including needle tubing and needle file, its characterized in that: 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, the encapsulating intracavity is equipped with glue, the horizontal liquid level of glue is less than the level at pilot hole top, perhaps, the horizontal liquid level of glue keeps unanimous with the level at pilot hole top, the top edge of needle tubing assembly base station forms the outer hem that turns over outward, the upper surface on this outer hem is arc surface or plane, the horizontal plane that outer hem peak formed in the space forms big plane 9, can provide great more comfortable contact surface when the injection.
The invention discloses a comfortable large-plane insulin pen needle, wherein the top edge of a needle tube assembly base station is designed into an edge which is folded outwards, so that a large annular contact surface is formed, a large and comfortable skin contact surface is provided, in order to further improve the touch feeling of a contact area, the liquid level of glue is controlled in a glue filling area, and the skin irritation of the contact area by the protruded glue is avoided. 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 large-plane insulin pen needle, which comprises a needle tube 1 and a needle seat 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 4 distributions of pilot hole, 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, glue 6's horizontal liquid level is less than the level at 4 tops of pilot hole, or, glue 6's horizontal liquid level keeps unanimous with the level at 4 tops of pilot hole, the top edge of needle tubing assembly base station 3 forms outside hem 7 of turning over and rolling over, outside hem 7 is by 11 hot-forming of deformation mould, circular arc surface 8 or plane are personally submitted to the upper surface of this outside hem 7. The outer folded edge can be a continuous annular structure or a plurality of disconnected annular structures formed in the middle, the diameter of the annular structure formed by the outer folded edge is 3mm-8mm, the curvature radius of the arc surface 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.
