Abstract
The utility model discloses a port for a flexible transfusion bag. The port is characterized by sequentially comprising a port welding end surface, a liquid isolation membrane, a butyl rubber plug and a port protective membrane from one end, which is in contact with a bag, of the port to the other end of the port, the port welding end surface, the liquid isolation membrane, the butyl rubber plug and the port protective membrane are integrally arranged to form the port, the port welding end surface is used for being welded with the bag, the liquid isolation membrane is used for isolating liquid medicine, the butyl rubber plug is used for sealing the port, and the port protective membrane is used for protecting and sealing the port. The port is of an integrally formed port structure, not only is applicable to a condition that a transfusion opening tube and a dosing opening are divided into more than two ports, but also is applicable to a condition that a transfusion opening tube and a dosing opening are combined with each other to form a port, is not communicated with the flexible transfusion bag during liquid filling, after liquid filling and before usage of the flexible transfusion bag as the port is welded on the bag of the flexible transfusion bag before liquid filling. Compared with the prior art, the port has the advantages that the possible pollution due to the port is prevented, the production cost is reduced, and the port is sanitary.
Description
Technical field
This utility model relates to a kind of medical infusion soft bag, particularly a kind of accessory of jumbo medical infusion soft bag.
Background technology
Existing large capacity transfusion packing container mainly contains several types commonly used such as vial, duroplasts bottle and transfusion bag.Vial needs constantly to introduce air through vent line in vial in infusion process, causes pollutant such as dust in air to enter and causes drug contamination in the vial; The hardness of duroplasts bottle is also bigger, still need use vent line; And transfusion flexible bag only just can make bag interior liquid export by the effect of external atmosphere pressure, need not to introduce air; And material is transparent, and is easy to use, obtains application more and more widely in present medical infusion.
The interface that existing transfusion flexible bag is used mainly comprises infusion port pipe and dosing mouth, and infusion port pipe and dosing mouth are by special-purpose sealing-plug and flexible pipe or special-purpose seal cover and special purpose interface sealing composition, owing to consider and irritate liquid efficient, the diameter of its infusion port pipe or dosing mouth often increases slightly, and the tensile force that the welding film that the diameter change causes infusion port pipe or dosing mouth to cover greatly on every side will bear will be big more, and then, in processes such as production, transportation and use, be subjected to external force effect generation seepage easily in the tension-thining thereupon of weld welding film.In addition, the infusion port pipe of prior art or the cost of dosing mouth are often higher, wherein a kind of transfusion flexible bag, its infusion port pipe and dosing mouth adopt special-purpose sealing-plug sealing, its complex structure, cost is higher, and sealing property is influenced by the process equipment precision in process of production; Also for dosing mouth adopts the ship shape interface, this interface overall dimension is bigger simultaneously for another kind of transfusion flexible bag, its infusion port pipe, and the welding position is more, causes cost higher.
The utility model content
The problems referred to above at the prior art existence, in order to reduce seepage, reduce production costs, this utility model provides a kind of transfusion flexible bag interface, adopt the interface structure of sealing-plug or seal cover and infusion port pipe or dosing mouth one, before irritating liquid, be welded on the bag of transfusion flexible bag in advance, in irritating obsolete processes such as liquid, transportation and preservation, no longer connect this infusion port pipe and/or dosing mouth, only connect in use, thereby kept health, avoid introducing and pollute, simultaneously do not need specialized designs sealing-plug or seal cover, reduced production cost.
A kind of transfusion flexible bag interface of this utility model; from an end to the other end order that contacts with bag comprise the joint weld end face, every liquid film sheet, butyl rubber plug, interface protection diaphragm; and they are wholely set into described interface; described joint weld end face is used for welding with bag; describedly be used to isolate medicinal liquid every the liquid film sheet; described butyl rubber plug is used for sealing, and described interface protection diaphragm is used for protection and sealing.
Further, described interface is more than one, and wherein having an interface at least is the infusion port pipe.
This utility model has adopted integrally formed interface structure, both be applicable to that infusion port pipe and dosing mouth separated the situation that is set to two above interfaces, be applicable to that also infusion port pipe and dosing mouth are set to the situation of an interface, because this interface was welded on the bag of transfusion flexible bag before irritating liquid in advance, in irritating liquid and after irritating liquid, use before this transfusion flexible bag, all disconnect above-mentioned interface, compared to existing technology, avoided introducing the possibility of polluting from seam, so need special-purpose complicated sealing-plug or seal cover be set at interface, reduced production cost, and health more.
Description of drawings
Fig. 1 is main TV structure figure of the present utility model;
Fig. 2 is a three-dimensional structure diagram of the present utility model;
Wherein: 18 interface protection diaphragms, 19 butyl rubber plugs, 20 every the liquid film sheet, 21 joint weld end faces.
The specific embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Embodiment 1
As Fig. 1-shown in Figure 2; this utility model transfusion flexible bag with interface from an end to the other end order that contacts with transfusion flexible bag comprise joint weld end face 21, every liquid film sheet 20, butyl rubber plug 19, interface protection diaphragm 18; and the said structure integrated setting becomes dosing mouth and infusion port pipe; joint weld end face 21 is used for welding with transfusion flexible bag; be used to isolate medicinal liquid every liquid film sheet 20; butyl rubber plug 19 is used for sealing, and interface protection diaphragm 18 is used for protection and sealing.Because before irritating liquid, dosing mouth and infusion port pipe have been welded on the transfusion flexible bag, and in irritating the liquid process, reach and irritate liquid end back before using this transfusion flexible bag, all can conducting dosing mouth and infusion port pipe, also just avoided prior art to irritate in the liquid process by dosing mouth and infusion port pipe, dosing mouth contacts with extraneous with the infusion port pipe, thereby introduces the possibility of pollutant.And, because dosing mouth of the prior art and infusion port pipe adopt special-purpose sealing-plug or sealed tube with fit system such as interference fit, matched in clearance, excessively mode such as cooperations seals, thereby may give the medicinal liquid introducing that is sealed small pollutant in size gap.And among this embodiment this utility model owing to passed through every liquid film sheet 20, butyl rubber plug 19, the 18 triple settings of interface protection diaphragm; and before irritating liquid, be welded on the bag by joint weld end face 21; afterwards until using just conducting dosing mouth and infusion port pipe; all the other all not conductings have improved health level.Simultaneously owing to have only in use just conducting, just need not be in prior art specialized designs sealing-plug or seal cover, its cost has also just reduced.
The transfusion flexible bag of present embodiment can be dosing mouth with interface, also can be the infusion port pipe.
A kind of transfusion flexible bag of this utility model is not limited to the above-mentioned embodiment that lists with interface.The person of ordinary skill in the field should know; more than describing only is specific embodiment of the utility model, and any pro forma change of on the basis of this utility model design this utility model being made or modification are all in protection domain of the present utility model.
