Pop-up insulin syringe needle

Abstract

The invention discloses a pop-up insulin syringe needle. The pop-up insulin syringe needle comprises an insulin pen, an injection syringe is arranged at one end of the insulin pen, a slide groove penetrates through an inner cavity of the injection syringe, an electromagnet is arranged on the inner wall of the slide groove, a magnet is arranged at one side of the electromagnet, a mechanical seal isarranged at one side of the magnet, a liquid injection pipe is arranged in an inner cavity of the slide groove, a nut is arranged on the outer wall of the liquid injection pipe, and a solid block isarranged at one side of the nut. By means of the pop-up insulin syringe needle, through the arrangement of the mechanical seal and the solid block, when a telescopic hose is aged after being used fora long time, medicine liquid is prevented from flowing out of gaps between the liquid injection pipe and the slide groove; meanwhile, the arc solid block can prevent dust from entering the slide groove from the gaps between the liquid injection pipe and the slide groove, and the service life is prolonged. According to the principle that objects with the same magnetism are repellant, a magnetic field of the electromagnet is utilized to push the magnet, the liquid injection pipe is driven to move in the side groove, a traditional push-pull structure is changed, and the pop-up insulin syringe needle is convenient to use; meanwhile, by means of the pop-up syringe structure, the using safety is improved.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a pop-up insulin needle. Background technique [0002] At present, the incidence of diabetes is increasing year by year. For diabetic patients, insulin is often injected for a long time to control the disease, and generally injections are performed before and after each meal. However, it is easy to stab the operator when the needle is returned after the injection is completed. [0003] Therefore, it is necessary to invent a pop-up insulin needle to solve the above problems. Contents of the invention [0004] The purpose of the present invention is to provide a pop-up insulin needle to solve the problems raised in the background art above. [0005] In order to achieve the above object, the present invention provides the following technical solutions: a pop-up insulin needle, including an insulin pen, an injection needle tube is provided at one end of the insulin pen, and a chu...
