Abstract
The utility model relates to a double-interface type three-layer extrusion film infusion bag which comprises a bag body, interfaces and polypropylene combined covers, wherein each interface comprises a substrate welded with the bag body into a whole in a heat seal manner and two oral tubes arranged on the substrate, the polypropylene combined covers are arranged at the upper ends of the two oral tubes respectively, each polypropylene combined cover comprises an outer cover and a polypropylene inner cover, easily-folded caps are arranged on the outer covers, isoprene gaskets corresponding to the easily-folded caps are arranged between the outer cover and the polypropylene inner covers, and one polypropylene combined cover and one oral tube form a liquid medicine adding tube or an infusion tube of the infusion bag respectively. In the utility model, the infusion tube is separated from the liquid medicine adding tube, so that liquid medicine is convenient to use in the clinic, and the diameters of the infusion tube and the liquid medicine adding tube are small, and when the infusion tube and the liquid medicine adding tube are filled with liquid medicine, the opportunity that the infusion tube and the liquid medicine adding tube are polluted is reduced. The liquid medicine adding tube is separated from the infusion tube, so that the infusion tube and the liquid medicine adding tube are dedicated, and when liquid medicine is added, the infusion port is not exposed in the air, thereby avoiding secondary pollution; and by adopting the easily-folded caps, when in use, the polypropylene combined covers are convenient to open and operate, which provide convenience for nursing personnel.
Description
Technical field
This utility model relates to medical infusion bags, refers in particular to the three-layer co-extruded film transfusion of a kind of double nip formula bag.
Background technology
Transfusion requires aseptic, and the transfusion overall process is closed state, to avoid air pollution.Yet transfusion is at present mostly adopted a single port pipe polypropylene list interface with bag, and all by with pipe flatly, same seal cover, bore are greatly, opportunities for contamination is big during fill in fill, dosing and infusion process; Dosing and infusion are with pipe, and the infusion point is exposed in the air during dosing, and contaminated, uneven drug level is too high, directly enter in patient's body, and infringement greatly; Air, antibacterial, virus entered in the medicinal liquid at the infusion point that has polluted easily when the slotting infusion of single tube list plug was penetrated; And the plastics draw ring, break easily during use bad, inconvenience.
Summary of the invention
The purpose of this utility model is improved and is innovated at the defective that exists in the background technology and problem, provides the three-layer co-extruded film transfusion of a kind of double nip formula with bag.
The technical solution of the utility model is a kind of transfusion bag that comprises bag, interface and polypropylene combination cover of structure, wherein interface comprises the pedestal and two piece mouth pipes being arranged on pedestal on integrally welded with the bag heat seal, and polypropylene combination cover is separately positioned on the upper end of two mouthfuls of pipes;
Described polypropylene combination cover comprises enclosing cover and polypropylene inner cap, enclosing cover is provided with easy-to-fold cap, be provided with the isoprene pad of corresponding easy-to-fold cap between enclosing cover and the polypropylene inner cap, and two polypropylene combination covers and two mouthfuls of pipes constitute chemical feed pipe or the tube for transfusion of transfusion with bag respectively.
Advantage of the present utility model and beneficial effect:
This utility model with tube for transfusion and chemical feed pipe separately makes things convenient for clinical application, and tube for transfusion and the chemical feed pipe bore is little, reduced opportunities for contamination during fill.Double bimouth pipe welding with multilayer co-squeeze film for transfusion on same pedestal is also easy; Chemical feed pipe and tube for transfusion have separately been accomplished special mouthful of special use, and infusion orifice is not exposed in the air during dosing, avoids secondary pollution; Composite cover adopts easy-to-fold cap, and convenient unlatching during use is convenient to nursing staff's operation.
Description of drawings
Fig. 1 is this utility model surface structure sketch map.
Fig. 2 is this utility model polypropylene combination cover and interface decomposition texture sketch map.
The specific embodiment
By Fig. 1,2 as can be known, comprise bag 7, interface 6 and polypropylene combination cover 5, wherein interface 6 comprises the pedestal 9 and two piece mouth pipes 8 being arranged on pedestal 9 on integrally welded with bag 7 heat seals, and polypropylene combination cover 5 is separately positioned on the upper end of two mouthfuls of pipes 8;
Described polypropylene combination cover 5 comprises enclosing cover 2 and polypropylene inner cap 4, enclosing cover 2 is provided with easy-to-fold cap 1, be provided with the isoprene pad 3 of corresponding easy-to-fold cap 1 between enclosing cover 2 and the polypropylene inner cap 4, and two polypropylene combination covers 5 and two mouthfuls of pipes 8 constitute chemical feed pipe or the tube for transfusion of transfusion with bag respectively.
Bag 7 described in the utility model is hot-forming by the three-decker co-squeeze film for transfusion.Described polypropylene combination cover 5 is integrally welded with mouthful pipe 8 heat seals.
Structural principle of the present utility model:
This utility model comprise multi-layer co-extrusion infusion with bag a bag 7, plastic container for infusion with polypropylene connector 6 and polypropylene combination cover for plastic infusion container 5, the mode that adopts heat seal to weld between bag 7 and polypropylene combination cover 5 and the interface 6 is connected.Interface 6 is made up of the pedestal 9 of the integral body of two mouth pipes 8 and lower ends that the upper end separates.Polypropylene combination cover 5 is made up of enclosing cover 2, isoprene pad 3 and polypropylene inner cap 4 with single easy-to-fold cap 1.
This utility model adopts the mode of heat seal once to be welded into the main body of three-layer co-extruded transfusion with bag the pedestal 9 of three-layer co-extruded film for transfusion and interface 6, comprises polypropylene connector 6 and bag 7.Two polypropylene combination covers 5 are welded on respectively on two mouth pipes 8 of polypropylene connector 6.
Embodiment described in the utility model only is the description that preferred implementation of the present utility model is carried out; be not that this utility model design and scope are limited; under the prerequisite that does not break away from this utility model design philosophy; engineers and technicians make the technical solution of the utility model in this area various modification and improvement; all should fall into protection domain of the present utility model; the technology contents that this utility model is asked for protection all is documented in claims.
