Description
Technical field
This utility model relates to the straight mouthful gasket seal of a kind of abnormal shape, belongs to the interior gasket seal of polypropylene combination cover for plastic infusion container of polypropylene transfusion flexible bag.
Background technology
Gasket seal material cost in the polypropylene combination cover for plastic infusion container of existing polypropylene transfusion flexible bag is high.Infusion vessel is the disposable infusion container, can not reclaim use again, and China has a large population, and has accounted for sizable ratio for patient's administration through the mode of transfusion.Big surprising of the transfusion consumption of every day is so the gasket seal of selecting to be suitable for seems even more important.
The utility model content
To the problem that existing situation exists, it is a kind of simple in structure, reasonable in design that the purpose of this utility model is to provide, the special-shaped straight mouthful gasket seal that cost of manufacture is low.
For realizing above-mentioned purpose; The special-shaped straight mouthful gasket seal of this utility model; Comprise straight mouthful of pad; The central part that is provided with inner groovy, lower surface at the central part of the upper surface of straight mouthful of pad is provided with inner groovy down, inner groovy and the symmetrical setting of following inner groovy this on, and the thin-wall construction that forms between the bottom land of two grooves is configured for the barrier layer that syringe needle punctures.
Further, said straight mouthful of pad is cylindrical structural.
Further, the said inner groovy of going up is arc groove with following inner groovy.
Further, be provided with protruding gasket ring on the upper surface of said straight mouthful of pad and the lower surface, this protruding gasket ring is arranged on the notch periphery of said arc groove.
Further, uniform distribution is provided with several anti-sticky points on the said protruding gasket ring.
Further, the quantity of said anti-sticky point is 4.
Further, said barrier layer thickness is 2mm.
This utility model is simple in structure, and is reasonable in design, and cost of manufacture is low, good airproof performance, and clinical manipulation is convenient.Thereby prolonged the effect duration of medicine, guaranteed the quality of medicinal liquid.
Description of drawings
Fig. 1 is the planar structure sketch map of this utility model;
Fig. 2 is the cross-sectional view of this utility model;
1 is straight mouthful pad, the 2nd among the figure, protruding gasket ring, the 3rd, anti-sticky point, the 4th, last inner groovy, the 5th, barrier layer, the 6th, following inner groovy.
The specific embodiment
Below, with reference to accompanying drawing, this utility model is more comprehensively explained, the exemplary embodiment of this utility model has been shown in the accompanying drawing.Yet this utility model can be presented as multiple multi-form, and should not be construed as the exemplary embodiment that is confined to narrate here.But, these embodiment are provided, thereby make this utility model, and the scope of this utility model is fully conveyed to those of ordinary skill in the art comprehensively with complete.
In order to be easy to explanation, here can use such as " on ", D score " left side " space relative terms such as " right sides ", be used for element shown in the key diagram or characteristic relation with respect to another element or characteristic.It should be understood that except the orientation shown in the figure spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device among the figure is squeezed, be stated as the element that is positioned at other elements or characteristic D score will be positioned at other elements or characteristic " on ".Therefore, the exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (revolve turn 90 degrees or be positioned at other orientation), and the relative explanation in used here space can correspondingly be explained.
Like Fig. 1, shown in Figure 2; The special-shaped straight mouthful gasket seal of this utility model comprises straight mouthful of pad 1, and a straight mouthful pad 1 is a cylindrical structural; The central part on the face of cylinder is provided with inner groovy 4 on straight mouthful pad 1, the central part on the face of cylinder is provided with inner groovy 6 down down; Last inner groovy 4 is arc groove with following inner groovy 6, last inner groovy 4 and following inner groovy 6 symmetrical settings, and the thin-wall construction that forms between the bottom land of two grooves is configured for the barrier layer 5 of syringe needle puncture.
Be provided with protruding gasket ring 2 on the upper surface of straight mouthful pad 1 and the lower surface, protruding gasket ring 2 is arranged on the notch periphery of arc groove, and uniform distribution is provided with several anti-sticky points 3 on the protruding gasket ring 2.The quantity of anti-sticky point 3 is 4 in the present embodiment.
The special-shaped straight mouthful gasket seal of this utility model is used for being combined into polypropylene inner cap, enclosing cover with plastic container for infusion the polypropylene combination cover for plastic infusion container of polypropylene transfusion flexible bag; Said enclosing cover and inner cap install on the straight mouthful gasket seal of this abnormal shape from the upper and lower cylinder cover of the straight mouthful gasket seal of this abnormal shape respectively; The corresponding part of last hypomere that is the straight mouthful gasket seal of this abnormal shape is fitted in the lid of said enclosing cover and inner cap, to be combined into said composite cover.The external diameter of last inner groovy 4 and following inner groovy 6 is less than the diameter of straight mouthful pad 1, and barrier layer 5 thickness are 2mm, is applicable to when the medical worker infuses to infuse, be prone to puncture with draw point dosing or resin pin; The effect of anti-sticky point 3 is to make the straight mouthful gasket seal of this abnormal shape on the composite cover track, to make things convenient for, and is conveyed into said inner cap efficiently, enclosing cover constitutes composite cover.
The special-shaped straight mouthful gasket seal of this utility model adopts polyisoprene rubber as raw material, is light blue pad.Compared with prior art, simple in structure, reasonable in design, convenience for washing, pollution-free, cost of manufacture is low, good airproof performance, clinical manipulation is convenient.Thereby prolonged the effect duration of medicine, guaranteed the quality of medicinal liquid.Its principle is: diameter be equally distributed 4 anti-sticky points on protruding gasket ring and the protruding gasket ring on the circular straight mouthful of pad of 7.5mm, with the plastic container for infusion of polypropylene transfusion flexible bag convex-concave ring realization dense block liquid with the polypropylene exterior and interior cover, production cost is low.
