Description

Technical Field

[0001] This utility model relates to the field of medicine bottle technology, specifically to an external interface tubular aseptic connector. Background Technology

[0002] External interface tubular aseptic connectors are interface caps on medicine bottles or medicine bags. They are used to seal the medicine after it has been filled, and also for infusion, injection, or dispensing after opening. They are an important component of medicine bottles and medicine bags.

[0003] To ensure the efficacy of the medication, special attention must be paid to sealing during transportation and storage. During transport and storage, the medication is frequently subjected to shaking, squeezing, and impacts, all of which can easily cause leakage at the sealing points, leading to damage, air ingress, and contamination by microorganisms, thus jeopardizing the therapeutic effect.

[0004] However, most of the external interface tubular connectors on medicine bottles and bags on the market have very simple internal structures, relying solely on an internal stopper and external sealing for sealing. This results in low reliability, and they are easily damaged, especially during long-distance and arduous transportation. Improvements are urgently needed. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an external interface tubular sterile connector, which solves the problem that the external interface tubular connectors on most medicine bottles and medicine bags on the market are too simple in structure, resulting in low sealing reliability.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: An external interface tubular sterile connector includes a connecting cap, a socket on the top of the connecting cap, a sealing film fixedly attached to the top of the connecting cap, a limiting cylinder at the position corresponding to the socket on the top of the inner wall of the connecting cap, a sealing plug being snapped into the inside of the limiting cylinder, a sealing pressure plate located below the limiting cylinder inside the connecting cap for supporting the sealing plug, and a connecting thread on the inner side wall of the connecting cap located below the sealing pressure plate. The top of the connecting cap is provided with an outer sealing ring ridge that protrudes upward and is concentric with the insertion hole, and the bottom of the limiting cylinder is provided with an inner sealing ring ridge that is coaxial with the limiting cylinder. The top of the sealing plate is provided with an outer sealing groove corresponding to the position of the limiting cylinder. The center of the outer sealing groove is provided with a downwardly recessed inner sealing easy-insertion groove. The bottom of the inner wall of the outer sealing groove is provided with an upwardly protruding reinforcing sealing ridge located at the edge of the inner sealing easy-insertion groove. The sealing plug is disc-shaped, and both the top and bottom centers of the sealing plug are provided with hemispherical easy-insertion grooves that are recessed towards the center. At the corresponding easy-insertion groove edges on the top and bottom of the sealing plug, there are snap-fit ​​sealing ring ridges that engage with the insertion hole and the inner sealing easy-insertion groove, respectively.

[0007] Preferably, the connector cap is cylindrical, and the insertion hole is located at the center of the top of the connector cap.

[0008] Preferably, one edge of the encapsulation film is provided with an integral tear tongue.

[0009] Preferably, the limiting cylinder, connecting cap, sealing plug, and sealing plate are coaxially arranged, and the limiting cylinder, connecting cap, outer sealing ring ridge, and inner sealing ring ridge are an integral structure.

[0010] Preferably, the outer sealing annular ridge has at least two rings.

[0011] Preferably, the snap-fit ​​sealing annular ridge and the sealing plug are an integral structure.

[0012] Compared with the prior art, the present invention has the following beneficial effects: This invention enhances the connection between the connecting cap and the encapsulation diaphragm and encapsulation pressure plate by setting a limiting cylinder, an outer sealing annular ridge, and an inner sealing annular ridge on the connecting cap. The encapsulation stopper enhances the connection between the connecting cap and the encapsulation pressure plate by setting a snap-fit ​​sealing annular ridge. The encapsulation pressure plate enhances the connection between the limiting cylinder and the encapsulation stopper by setting an outer sealing groove, an inner sealing easy-insertion groove, and a reinforcing sealing protrusion. Through the interlocking and compression cooperation between the components, multiple protective effects are achieved, significantly improving the reliability of the seal. This solves the problem that the external interface tubular connector structure on most medicine bottles and medicine bags on the market is too simple, resulting in low sealing reliability.

A sealing pressure plate 4 is provided inside the connecting cap 1 below the limiting cylinder 102 to support the sealing plug 3. A connecting thread 103 is provided on the inner side wall of the connecting cap 1 below the sealing pressure plate 4. The top of the connecting cap 1 is provided with an outer sealing ring rib 104 that protrudes upward and is concentric with the insertion hole 101. The outer sealing ring rib 104 has at least two rings. The bottom of the limiting cylinder 102 is provided with an inner sealing ring rib 105 that is coaxial with the limiting cylinder 102. The limiting cylinder 102, the connecting cap 1, the sealing plug 3 and the sealing pressure plate 4 are coaxially arranged.
