The single-end single-plug combined cover for the infusion bag comprises an outer cover, a rubber plug, a rubber plug pressure pad and an adhesive film. The outer cover is actually cylindrical, a protruding rubber plug chamber is arranged on the top of the outer cover, and the rubber plug is integrally in a 8 shape, and is fixedly arranged in the rubber plug chamber; the rubber plug pressure pad is fixed to the top of the rubber plug in a sealed mode, and is flush with the upper surface of the rubber plug chamber; the adhesive film is processed in a sealing mode, and then covers the upper surface and the side of the rubber plug chamber. Circular sunken portions which are used for medicine feeding and infusion are arranged at the two ends of the rubber plug, and a protrusion in the middle of the rubber plug pressure pad is matched with a groove in the middle of the rubber plug to enable the medicine feeding sunken portion and the infusion sunken portion to be separated, so that contamination is avoided; the structures of the rubber plug chamber, the rubber plug and the rubber plug pressure pad are optimized, so that the rubber plug chamber, the rubber plug and the rubber plug pressure pad are in close fit, and the integral structure is firm and closed; the adhesive film is processed in the sealing mode, so that safety is guaranteed; when the single-end single-plug combined cover for the infusion bag is used, only the adhesive film needs to be torn away, and operation is convenient.
Description
Technical field
The present invention relates to technical field of medicine packaging, particularly relate to a kind of transfusion bag single head list plug composite cover.
Background technology
Along with the generally application of infusion treatment, infusion model have passed through from open, semi open model to fully closed evolution, and transfusion device thereupon by vial change the soft bag of non-PVC composite membrane of today into.For realizing dosing and transfusion, in soft bag, be generally provided with transfusion cork and medicine plug.In prior art, mainly contain two schemes, one is that transfusion cork and medicine plug are independent, and adopt two rubber stoppers, its production cost is larger; Another kind of transfusion and dosing share a rubber stopper, but easily pollute.Install in addition, to change dressings and the operating process requirement transfusion cork such as dosing has convenience, agility, practicality, in infusion process, require that transfusion cork has sealing for the security consideration of patient.The huge market demand and the mass of production require that again transfusion cork has low cost.Therefore need a kind of good seal performance, exempt to pollute, low, the convenient and practical transfusion bag combined cover of cost.
Summary of the invention
For the deficiency of prior art, the object of this invention is to provide a kind of transfusion bag single head list plug composite cover.
In order to realize object of the present invention, the present invention adopts following technical scheme:
A kind of transfusion bag single head list plug composite cover, comprise enclosing cover, plug, plug pressure pad and pad pasting, wherein, described enclosing cover is substantial cylindrical shape, has the plug room of protrusion above it; Described plug is on the whole in " 8 " font, and it is indoor to be fixed on described plug; Described plug pressure pad sealing is fixed on above described plug, and is positioned at the upper surface flush of described plug indoor and plug room; Described pad pasting is covered in upper surface and the side of described plug room after encapsulation process.
Further, described plug room is divided into plug accommodation section and plug pressure pad accommodation section, and described plug indoor have the fixture of locating and fixing described plug.
Further, the exterior contour of described plug room is symmetrical polygon, the match profiles of its in-profile and described plug is closed, the mid portion of both sides has inside arcuate projections, bottom edge region and mid portion have for locating and fixing the projection of described plug, and the wall of the both sides of described plug room is higher than the upper surface of plug room, its centre position exceeding the part of upper surface has V-type groove.
Further, have two circular depressed that diameter is 4.5mm at the two ends of the upper and lower surface of described plug respectively, described depression is respectively used to transfusion and dosing.
Further, the marginal portion on the upper and lower surface of described plug and mid portion have rectangular recess.
Further, the two ends of described plug pressure pad have the circular hole that diameter is 7mm.
Further, the upper surface of described plug pressure pad is horizontal plane, its lower surface edge part has the lobe with the fit depressions of the marginal portion of described plug, and the side of described plug pressure pad has the cocked bead matched with the plug accommodation section of described plug room.
Further, described pad pasting sealing covers the upper surface of described plug pressure pad, and it is indoor to be positioned in fact described plug.
Further, described enclosing cover and plug pressure pad are made by PP material, and described plug is made up of isoprene rubber.
Further, described pad pasting is aluminium foil or plastic adhesive film.
Adopt technique scheme, beneficial effect of the present invention is:
Composite cover of the present invention only has a plug room, simplifies the production technology of product, reduces production cost; Composite cover of the present invention only needs a plug, described plug has respectively the depression for dosing and transfusion, and there is plug pressure pad, not only realize the fixing of plug, and coordinating described dosing to cave in and infuse to cave in and separate by the projection of intermediate portion and plug mid portion groove, avoid pollution; Be optimized process to the structure of described plug room, plug and plug pressure pad, three is closely cooperated, overall structure firmly and sealing; Pad pasting through encapsulation process, and ensures safety; Use and only need tear pad pasting off, easy to operate.By the V-type groove above plug room, described pad pasting is divided into two pad pastings, the pad pasting of dosing depression and transfusion depression top can be torn during use respectively off, realize dosing or transfusion, make its safety and sanitation more.
