Pen type syringe needle simply packaged and use method thereof

Abstract

The invention discloses a pen type syringe needle simply packaged and a use method of the syringe needle. The syringe needle comprises at least one needle body and at least one packaging body used for packaging the needle body. Each needle body comprises a needle base, a needle tube and an inner protecting cap, wherein the needle base, the needle tube and the inner protecting cap are sequentially connected. Each packaging body comprises a packaging cup and seal paper. Each packaging cup is provided with at least one cavity matched with the corresponding needle body. At least one axial protrusion is arranged on the outer peripheral face of each needle base. Grooves connected with the axial protrusions in a matched mode are formed in the inner walls of the cavities. The edges of the upper portions of the cavities are arranged to be planes. The seal paper is connected with the planes in a matched mode. By means of the mode, the pen type syringe needle simply packaged and the use method of the syringe needle enable the whole production process to be simpler and easier to implement and the sealing process to be easier, remarkably improve the reliability of sterility sealing, reduce the product cost greatly, are particularly suitable for batch production, and have high economic value.

Description

technical field [0001] The invention relates to the field of aseptic packaging of medical pen-type syringe needles, in particular to a simple-package pen-type syringe needle and a use method thereof. Background technique [0002] Existing pen syringe needles such as Figure 1-Figure 3 As shown, the needle is sealed in it by the outer protective cap 1 and the medical sealing paper 2 . When in use, the sealing paper 2 needs to be torn away from the bonding point 3 and the outer protective cap 1 to expose the sterile needle 5 therein, screw it onto the pen-type syringe 4, pull out the outer protective cap 1, pull out the inner protective cap 6, The needle tube 7 is exposed, and the outer protective cap 1 must be covered at least after the injection is completed, and the whole pen syringe needle is unscrewed. This primary packaging structure using the outer protective cap 1 and a separate sealing paper 2 has high requirements on the automated production process, especially the ...

AI Technical Summary

Problems solved by technology

In addition, the bonding point 3 between the sealing paper 2 and the outer protective cap 1 also requires a process, and multiple products are also packaged into bags and / or boxes, and the accurate counting process is also very complicated. Therefore, this high-precision process Requirements and complex assembly processes make pen injector needles expensive
