Description

Technical Field

[0001] The utility model relates to the technical field of medicinal gaskets, in particular to an annular sealing structure of a medicinal gasket. Background Art

[0002] Synthetic polyisoprene gaskets are a common seal used in conjunction with multi-layer co-extruded infusion bags or plastic infusion bottles in the field of medicinal material packaging. In recent years, the use of medicinal synthetic polyisoprene gaskets has been increasing year by year. The production of medicinal synthetic polyisoprene gaskets requires processes such as compounding, preforming, vulcanization molding, edge removal, cleaning, and packaging.

[0003] There is an oil-resistant medicinal gasket with patent publication number CN203017386U, which uses rubber molecules containing polar groups, such as cyano, ester, hydroxyl, chlorine atoms, etc., which make the rubber exhibit polarity. When the highly polar rubber comes into contact with non-polar oils, the polarity difference between the two is large, and the rubber is not easy to swell, thereby ensuring the sealing of the combined cover; and the groove design can be used as an infusion hole, a dosing hole and a ventilation hole respectively, which is easy to puncture and also saves materials.

[0004] However, this structure has the risk of fragments being formed at the damaged part of the gasket during puncture, which may flow into the liquid medicine and cause contamination, resulting in poor reliability. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the utility model provides a ring-shaped sealing structure of a medicinal gasket with a prefabricated loose opening in the middle, which can be initially bonded with glue. When the infusion head is punctured, the glue can be directly pierced and the gasket can be stretched out through the prefabricated loose opening, avoiding the generation of fragments by cutting the gasket body and improving reliability.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a ring-shaped sealing structure of a medicinal gasket, comprising a rubber stopper, an upper sealing ring gasket, a lower sealing ring gasket, a prefabricated loose opening and adhesive, wherein the top ring side of the rubber stopper is connected to the bottom side of the upper sealing ring gasket, the bottom ring side of the rubber stopper is connected to the top side of the lower sealing ring gasket, a prefabricated loose opening is provided in the middle of the rubber stopper, and adhesive is provided in the prefabricated loose opening.

[0007] Preferably, it further comprises an adhesive ring, and the middle ring side of the top end of the upper sealing ring gasket is connected to the bottom side of the adhesive ring.

[0008] Preferably, a guide sleeve is further included, and the middle ring side of the bottom end of the rubber stop pad is connected to the top end of the guide sleeve.

[0009] Preferably, it also includes absorbent cotton, a hole, a connecting piece and a sticking piece. The inner side of the guide sleeve is movably plugged with the outer side of the upper part of the absorbent cotton. The middle parts of the left and right sides of the top of the absorbent cotton are respectively connected to the bottom side of a group of connecting pieces. A group of sticking pieces is respectively provided on the inner side of each group of connecting pieces, and a hole is provided through the middle of the absorbent cotton.

[0010] Preferably, it further comprises a connecting strip and a pull ring, and one side of the bottom end of the rubber stopper is connected to the middle part of the top side of the pull ring via the connecting strip.

[0011] Compared with the prior art, the present invention provides an annular sealing structure of a medicinal gasket, which has the following beneficial effects:

[0012] The rubber stopper contacts the bottle mouth through the upper sealing ring gasket and contacts the inner wall of the cover through the lower sealing ring gasket to form a seal at the contact point. When in use, medical staff insert the infusion head into the rubber stopper, which can first destroy the glue, puncture upward through the prefabricated loose opening, and then insert it into the medicine liquid. A prefabricated loose opening is set in the middle, and preliminary bonding can be performed with glue. When the infusion head is punctured, the glue can be directly pierced and stretched out through the prefabricated loose opening to avoid cutting the pad body and producing fragments, thereby improving reliability.
