Integrated three-tube three-valve large transfusion soft bag and bottle packaging plastic double-color cover

Abstract

The invention discloses an integrated three-tube three-valve large transfusion soft bag and bottle packaging plastic double-color cover, which comprises a cover, blind tubes protruding from the top face of the cover, valve plugs arranged in the blind tubes, and easily foldable handles arranged on the top faces of the blind tubes, wherein the top face of the cover has three blind tubes with valve plugs; and the cover and the valve plugs are formed in an integrated structure and are connected into a whole by plastic injection molding. The valve plugs are made of a thermoplastic polyolefin elastomer (TPE) material and have high medicament compatibility, and therefore avoid causing medicaments to deteriorate. The finished product has the advantages of high elasticity and high flexibility, canprevent scraps and liquid leakage during puncturing and can be safely sealed after puncturing, so the pollution problem caused by scraps and liquid leakage during puncturing to the medicaments is solved, and the safety of clinic use is improved greatly. Made of a plastic material, both the cover and the valve plugs can be formed by plastic injection molding on one plastic injection molding machine; therefore, the production process is greatly shortened and the production cost is reduced.

Description

technical field [0001] The invention relates to the field of medical supplies, in particular to bags and bottles for storing medicinal liquid. Background technique [0002] At present, the infusion ports of bags and bottles used for patient infusion are generally provided with combined caps. The rubber stopper in the tube is formed. The outer cover and the inner cover of the existing combination cover are made of polypropylene material, and what the rubber plug adopts is polyisoprene material. The production process of the existing combination cap is to pack the outer cover, the inner cover and the rubber plug separately after they are formed, and then manually send them into the cap assembly unit to press them into a cap, and then pass the manual inspection to become a finished composite cap. As can be seen from the above, the existing combined cover has the following defects: [0003] One is that there are many production processes, a long cycle and high cost; the other...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is to provide an integrated large infusion soft bag with three tubes and three valves, and a plastic two-color cover for bottle packaging. 1. The valve plug material of the plastic double-color cap used for bottle packaging overcomes the defects of the existing technology such as many production processes, high cost, air leakage, liquid leakage during use, and liquid medicine pollution caused in the process of production, storage, and use.
