Abstract
The invention discloses a special double-head connector for an infusion bag. The special double-head connector comprises a connector base connected with the infusion bag; the upper end of the connector base is provided with an infusion connector and a dosing connector which are mutually parallel; a combined cover is welded above the infusion connector; the upper part of the combined cover is fixedly provided with an infusion rubber plug in a manner that the upper part of the combined cover is folded inwards; the lower part of the infusion rubber plug is supported by an inner cover diaphragm; the inner cover diaphragm and the combined cover form a whole in an injection molding manner; the upper end of the dosing connector is fixedly provided with a dosing rubber plug in a manner that the upper end of the dosing connector is folded inwards; a puncture diaphragm supports below the dosing rubber plug; the puncture diaphragm and the dosing connector form a whole in the injection molding manner; the infusion connector and the combined cover are welded in an aluminum foil welding manner, and two welding lines are welded; protective films are respectively pasted to upper ends of the combined cover and the dosing connector. The special double-head connector disclosed by the invention is reasonable in structural design, strong in airtightness and safe and reliable.
Description
Technical field
The present invention relates to the field of medical apparatus and instruments, specifically, is the special double end interface of transfusion bag.
Background technology
The transfusion bag of double end interface, because dosing and transfusion are separated from each other, is independent of each other dosing and transfusion, and dosing is convenient, is difficult for causing cross infection, therefore obtains clinically applying more and more widely.In existing double end interface, infusion connector adopts the folding form of pulling, cut channel position easily split by the impact of external force and high temperature embrittlement easily causes polluting, opening force is also unstable simultaneously, the seal cover of upper end adopts exterior and interior cover, the mode of rubber plug combination assembling, exterior and interior cover mating part is gapped, in assembling process, easily there is poor fit, in the time of welding, can often there is not while firm welding phenomenon of exterior and interior cover simultaneously, cause air-tightness good not, in addition, dosing interface section adopts the fixing plug of the mode of buckle, when dosing is outwards pulled out pin, have the risk that plug is taken out of together.
Therefore, provide a kind of good airproof performance, plug that transfusion bag double end interface more firm, more reasonable structure is installed real in necessary.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the invention provides the special double end interface of transfusion bag, comprise the interface pedestal being connected with transfusion bag, the upper end of described interface pedestal is provided with the infusion connector and the dosing interface that are parallel to each other, the top of described infusion connector is welded with composite cover, the top of described composite cover is fixed with transfusion rubber plug by the mode of inside flanging, the bottom of described transfusion rubber plug is supported by inner cap barrier film, described inner cap barrier film and composite cover injection mo(u)lding are integrated, the inside flanging in upper end of described dosing interface is fixed with dosing plug, the below of described dosing plug is supported by the barrier film that punctures, described puncture barrier film and the injection mo(u)lding of dosing interface are integrated.
Wherein, between described infusion connector and composite cover, adopt the mode of aluminium foil welding to weld.
The upper end of described composite cover and dosing interface is pasted with respectively protecting film.
The invention has the beneficial effects as follows:
1) between infusion connector and composite cover, adopt the mode of aluminium foil welding, and be welded with twice sealing wire, guaranteed sealing and the intensity of welding, avoided draw ring and pulled folding mode cut channel position split by the impact of external force, and caused the phenomenon of internal contamination.
2) composite cover of infusion connector adopts the coated technique of flanging, make the location of plug and tightr with coordinating of enclosing cover, dosing part also adopts the coated structure of flanging, make plug fixing tightr, avoid after dosing, pulling out the risk that pin is taken plug out of, made whole device more safe and reliable.
3) infusion connector part adopts without inner cover structure, and the direct injection mo(u)lding of inner cap barrier film and composite cover form one, have avoided traditional group closing lid inner cap to coordinate with enclosing cover and have not closely caused the phenomenon into water, make whole sealing stronger.
Accompanying drawing explanation
Fig. 1 is front view of the present invention.
Fig. 2 is assembling exploded view of the present invention.
Fig. 3 is cutaway view of the present invention.
Wherein, 1-interface pedestal, 2-infusion connector, 3-dosing interface, 4-composite cover, 5-transfusion rubber plug, 6-inner cap barrier film, 7-dosing plug, the 8-barrier film that punctures.
The specific embodiment
As shown in Figure 1, the special double end interface of transfusion bag of the present invention, comprise the interface pedestal 1 being connected with transfusion bag, the upper end of described interface pedestal 1 is provided with the infusion connector 2 and the dosing interface 3 that are parallel to each other, the top of described infusion connector 2 is welded with composite cover 4, the top of described composite cover 4 is fixed with transfusion rubber plug 5 by the mode of inside flanging, the bottom of described transfusion rubber plug 5 is supported by inner cap barrier film 6, described inner cap barrier film 6 is integrated with composite cover 4 injection mo(u)ldings, the inside flanging in upper end of described dosing interface 3 is fixed with dosing plug 7, the below of described dosing plug 7 is supported by the barrier film 8 that punctures, described puncture barrier film 8 is integrated with 3 injection mo(u)ldings of dosing interface, between described infusion connector 2 and composite cover 4, adopt the mode of aluminium foil welding to weld, the upper end of described composite cover 4 and dosing interface 3 is pasted with respectively protecting film.
When the present invention works, be tightly connected by interface pedestal 1 and transfusion bag, tear the protecting film on dosing interface 3, the syringe needle of needle tubing through dosing plug 7 and puncture barrier film 8 to dispense medication in transfusion bag, after having infused, tear the protecting film on composite cover 4 tops, Transfusion needle pipe through transfusion rubber plug 5, inner cap barrier film 6, enters transfusion bag successively, can infuse.This infusion bag opener adopts the fixing dosing plug 7 of flanging mode in dosing interface 3 parts, avoid pulling out after dosing the risk that pin is taken dosing plug 7 out of, infusion connector 2 adopts the mode of aluminium foil welding to weld with composite cover 4, and is welded with twice sealing wire, has guaranteed sealing and the intensity of welding, in addition, inner cap barrier film 6 adopts the design with composite cover 4 integrative-structures, has avoided drainage, whole double nip reasonable in design, sealing is strong, safe and reliable.
