Embodiment Construction

[0023] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing:

[0024] Such as figure 1 As shown, a bionic anti-needle pain-relief intravenous injection needle is composed of a bionic pain-relief needle main body 1 and a flexible anti-detachment needle drag-reducing expansion layer 2 coated on the outside of the bionic pain-relief needle main body 1 . The bionic pain-reducing needle main body 1 includes a needle tube section and a bionic drag-reducing pain-reducing needle tip extending from the needle tube section, and a needle tube anti-dropping link is also provided between the needle tube section and the bionic drag-reducing pain-reducing needle tip.

[0025] The bionic drag-reducing and pain-reducing needlepoint is figure 1 In the middle BC section, the drag reduction curve structure imitating the dog teeth of a badger is adopted, such as figure 2 As shown, in the coordinate system with the center axis of the...

Abstract

The invention discloses a bionic analgesia-relief intravenous injection needle for anti-dropout, which is composed of a bionic pain-relief needle main body and a flexible anti-off-needle anti-needle drag-reduction expansion layer coated on the outside of the bionic pain-relief needle main body; the bionic pain-relief needle main body includes a needle tube section and the bionic drag-reducing and pain-reducing needle point extended from the needle tube section, and a needle tube anti-dropping link is also set between the needle tube section and the bionic drag-reducing and pain-reducing needle tip. The bionic drag-reducing and pain-reducing needle tip adopts a drag-reducing curve structure imitating a badger’s canine teeth; the needle tube anti-dropping link adopts a drop-shaped curve structure; Molecular weight polyethylene composition. The present invention adopts the research method of bionics, reduces the pain in the process of piercing the skin through the design of the needle tip structure, and reduces the risk of needle removal during the intravenous injection process through the design of the anti-disconnection link.

Description

technical field [0001] The invention relates to a medical syringe needle, in particular to a bionic analgesia-reducing intravenous injection needle for anti-dropping. Background technique [0002] In the existing medical process, most of the drug injections are injected into the body through pressure after the needle is pierced into the skin. Movement during IV administration can lead to needle dislodgement problems, especially in pediatric settings. Contents of the invention [0003] In order to solve the above-mentioned problems existing in the prior art, the present invention provides a bionic pain-reducing intravenous injection needle for anti-dropping, adopting bionics research methods, reducing the pain in the process of piercing the skin through the design of the needle tip structure, and reducing the pain through the design of the anti-dropping link. Risk of needle dislodgement during IV administration. [0004] The purpose of the present invention is achieved th...
