Combination cap, double-valve upright infusion bag and preparation method thereof

Abstract

The invention provides a combination cap, a double-valve upright infusion bag and a preparation method thereof. The combined cover includes an outer cover (1), an inner cover (2) and a gasket (3) arranged between the inner cover (2) and the outer cover (1). The gasket (3) is an integrated design, including part Two overlapping circular parts, the two circular parts are combined to form a butterfly shape, the top of the outer cover (1) is provided with an opening boss (4), and the inner side of the opening boss (4) is provided with a gasket (3) Matching slots. According to the combination cap of the present invention, the gasket can provide greater retraction force, so that the colloid of the gasket can hold the needle tightly without leakage, and the design is reasonable, safe and reliable. The double-valve stand-up bag infusion package is controlled by dual valves in the dosing and infusion channels, which can reduce disinfection and pollution, and there is no need for air intake during infusion, and it automatically shrinks, which can avoid secondary pollution and make dosing more convenient.

Description

technical field [0001] The invention relates to the field of medical packaging, in particular to a combination cap, a double-valve standing infusion bag and a preparation method thereof. Background technique [0002] At present, medical infusion bags or bags use a sealed combination cover, which is mostly composed of three parts: an outer cover, a gasket and an inner cover; the pharmaceutical factory pours the liquid medicine into the infusion bag and then heats and welds the combination cover on the bag mouth for sealing. There is a pull ring on the cover. When the medical personnel give medicine to the patient, they can pull up the pull ring of the outer cover, so that the connecting part of the outer cover is separated from the outer cover to expose the gasket. Inject or output liquid medicine. The function of the gasket is mainly for better sealing and avoiding leakage of the liquid medicine during infusion. In order to avoid secondary disinfection during infusion afte...

AI Technical Summary

Problems solved by technology

[0003] The existing double-valve easy-folding combined cover has an inner pad divided into a 400m track type and a dumbbell shape (also known as a figure 8 shape). The shape of the 400m track type inner pad is like the shape surrounded by a 400m track. Or the gasket slips easily after the infusion set is pierced, causing liquid leakage; the disadvantage of the dumbbell shape (figure 8) is that after the syringe or the infusion set is pierced, it is easy to insert the inner pad into the bottle, and the gasket is pierced by the needle. Finally, the retraction force is limited, and the puncture hole cannot be retracted tightly with the puncture needle, especially the radius of the circular part is too small, which is prone to leakage during infusion
