Problems solved by technology

The soft bag interface of the prior art is mainly composed of an interface body, an inner cover, an outer cover and a gasket. Although the technology is mature, there are still the following deficiencies: 1. There are many parts in contact with the liquid medicine (the interface body and the inner cover are all in contact with the liquid medicine). liquid contact), resulting in poor sealing; 2. The production process is complicated; 3. Air leakage is easy to occur when inserting and pulling out the needle, and secondary pollution may occur.

Embodiment 1

[0040] as attached figure 1 As shown, the one-time molded soft bag interface is mainly composed of an interface body 1, a rubber plug 2, a sealing diaphragm 3, a sealing pressure ring 4 and a sealing film 5.

[0041] The interface body 1 is a one-time molding structure, with a drug infusion channel 1-1 inside, a sealing port 1-2 at one end, and a welding part 1-3 at the other end.

[0042] The sealing port 1-2 is used to cooperate with the rubber plug 2, the sealing diaphragm 3, the sealing pressure ring 4 and the sealing film 5 to form the sealing structure of the interface. The sealing port 1-2 is coaxially arranged on the upper end of the interface body 1, and its inner diameter is slightly larger than the diameter of the drug delivery channel 1-1, and is located at the junction of the sealing port 1-2 and the drug delivery channel 1-1. Form a shoulder. The sealing diaphragm 3 is fixedly arranged on said shoulder. The sealing film 5 is fixedly arranged at the opening end...

Embodiment 2

[0048] as attached figure 2 As shown, the once-formed soft bag interface is mainly composed of an interface body 1, a rubber plug 2, a sealing diaphragm 3, a sealing pressure ring 4 and a sealing pull ring 9.

[0049] The structure and connection relationship of the interface body 1, the rubber plug 2, and the sealing pressure ring 4 are basically the same as those in the first embodiment. The main differences are:

[0050] 1. The sealing diaphragm 3 is integrally formed with the interface body 1, and its position is located at the shoulder;

[0051] 2. A sealing pull ring 9 is fixed on the top of the sealing pressure ring 4, and the dustproof effect is achieved through the sheet-shaped sealing structure of the sealing pull ring 9.

Embodiment 3

[0053] as attached image 3 As shown, the once-formed soft bag interface is mainly composed of an interface body 1, a rubber plug 2, a sealing diaphragm 3, a sealing pressure ring 4 and a sealing pull ring 9.

[0054] The structure and connection relationship of the interface body 1, the rubber plug 2, the sealing diaphragm 3, and the sealing pressure ring 4 are basically the same as those in the first embodiment. The main difference is that a sealing ring 9 is fixed on the top of the sealing pressure ring 4 , and the dust-proof effect is achieved through the sheet-shaped sealing structure of the sealing ring 9 .

Abstract

The invention discloses a once-formed soft bag connector, and belongs to the field of large infusion packages. The once-formed soft bag connector structurally comprises a rubber plug and a connector body with a medicine infusion channel. The rubber plug is arranged at the end of the connector body. The once-formed soft bag connector is characterized in that a sealing opening is formed in the end of the connector body, the inner diameter of the sealing opening is slightly larger than the diameter of the medicine infusion channel, a shoulder portion is formed at the joint of the sealing opening and the medicine infusion channel, a sealing pressing ring is arranged on an inner circle of the upper end of the sealing opening, and the rubber plug is arranged between the sealing pressing ring and the shoulder portion and abuts against the sealing opening in a pressed mode through the sealing pressing ring and the shoulder portion. Compared with the prior art, the once-formed soft bag connector has the advantages of being simple in technology, good in sealing performance and the like, and has the good application and popularization value.

Description

technical field [0001] The invention relates to the field of large transfusion packaging, in particular to a once-formed soft bag interface and an infusion soft bag with the soft bag interface. Background technique [0002] Due to the self-shrinkage of the soft bag packaging, the drug solution can be dripped out by its own tension without the need for catheter ventilation during infusion, without the need to form an air circuit, which can greatly reduce the probability of secondary pollution and cross-infection, and the soft bag packaging method has the advantages of occupancy Small size, light weight, easy storage and transportation, etc. Therefore, the proportion of soft bag packaging in large infusion solution packaging is increasing. [0003] The soft bag interface is one of the main structures of the soft bag packaging, which is used to insert pins and avoid liquid leakage, air leakage, etc. The soft bag interface of the prior art is mainly composed of an interface...
