Anti-needle structure and injection needle comprising same

Abstract

The invention discloses an anti-acupuncture structure and a syringe needle including the same. The anti-acupuncture structure includes a needle base, wherein the upper end of the needle base is used for fixing a needle head; a plurality of slide members, wherein the plurality of slide members are cylindrical and have two opened ends each, the innermost slide member can slidingly sleeve the needle base, the total length of the plurality of slide members in the slide direction is greater than the length of the needle head, one or more fasteners are arranged on the lower end of each slide member, and circular clamping grooves are formed in the upper ends of all the slide members between the outermost slide member and the needle base, and the need base; The fastener and the circular clamping grooves can be jointed together so as to limit sliding of the innermost slide member relative to the needle base and mutual slide among a plurality of slide members. The slide members can be unfolded layer by layer so as to hide the needle heat in use and after use, the safety is improved, and pain of a patient can be relieved; the plurality of slide members and the needle base can be fixed through the plurality of fasteners and the plurality of clamping grooves, and this fixing manner is more stable.

Description

technical field [0001] The invention relates to an anti-needle structure and an injection needle comprising it. Background technique [0002] At present, before the commonly used injection needles are used, the needle needs to be covered with a needle cover to protect the needle, for example, to prevent the needle from being bent or collided. During use, when the needle cover is pulled out, it is easy to cause a risk of stabbing, but the real danger is in the disposal stage after the injection is completed. There is a danger of being easily stabbed when the needle cover is put on, causing serious consequences such as infection of medical staff. [0003] In response to this defect, some injection needles have adopted the technical means of a retractable needle. After the injection is completed, the needle is retracted into a structure such as a protective cover for protecting the needle by utilizing the elastic force of a spring or other structure. In this way, although the...

Problems solved by technology

In this way, although the needle can be effectively protected and the medical staff can be prevented from being stabbed, it will cause great pain to the patient due to the mechanical action of the needle retraction.

[0004] On the other hand, when the retractable needle is retracted, there is often a gap in the retractable mechanical structure, which may clamp the skin and cause greater pain to the patient
