Detailed description of the invention
Below, with reference to accompanying drawing, this utility model is more fully illustrated, shown in the drawings of exemplary embodiment of the present utility model.But, this utility model can be presented as multiple multi-form, is not construed as the exemplary embodiment being confined to describe here.And it is to provide these embodiments, so that this utility model is fully and completely, and scope of the present utility model is fully conveyed to those of ordinary skill in the art.
For ease of explanation, here can use such as " on ", the space relative terms such as D score " left " " right ", for shown in explanatory diagram a element or feature relative to another element or the relation of feature.It should be understood that in addition to the orientation shown in figure, spatial terminology is intended to include device different azimuth in use or operation.Such as, if the device in figure is squeezed, be stated as being positioned at the element of other elements or feature D score will be located into other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower both orientation.Device can otherwise position (90-degree rotation or be positioned at other orientation), relatively illustrates used herein of space correspondingly to explain.
As shown in Figure 1 to Figure 3, a kind of one-body molded composite cover of this utility model, including lid 1, plug 2 and easily tore film 3, wherein, lid 1 includes plug chamber 5, tube for transfusion 6 and connecting tube 8 the most successively, and the upper port correspondence in plug chamber 5 seals and is provided with easily tore film 3.
Plug chamber 5 is provided with sealing barrier film 4 with the intersection of tube for transfusion 6, and sealing barrier film 4 is planar structure, and thickness is 0.3-0.8mm, and without leak when this thickness had both ensured to be molded, when ensureing again transfusion, puncture needle easily pierces through sealing barrier film, does not ensures bits simultaneously.In actually used, barrier film 5 can be sealed according to demand and be set to various structures pattern.Seal barrier film 4 and not only act as sealing, also as the substrat structure of plug 2 injection.
During injection, plug 2 can be close to seal barrier film 4 and be molded, plug 2 is bonded together with sealing barrier film 4.After the direct injection molded thermoplastic's elastomer in plug chamber 5, the plug 2 that this thermoplastic elastomer (TPE) is directly molded combines together with plug chamber 5, and is fully sealed by plug chamber 5 upper opening.Plug 2 uses polystyrene type elastomer or butyl rubber class elastomer to make.
A kind of one-body molded infusion bag fitting of this utility model is to use double material injection molding machine integral molded plastic molding, and lid 1 is made in first injection, is then directly molded plug 2 in plug chamber 5.
The upper port edge in plug chamber 5 is outward extended with welding ring 7.Easily tore film 3 can be integral membrane structure so that the upper surface of lid 1 is completely covered, its upper port is sealed.In the present embodiment, use easily tore film 7 corresponding to sealing fluid passage 4, outside can be effectively isolated, thus avoid the danger of cross infection.Fluid passage 4 can be used for liquid feeding, takes liquid, transfusion etc..For convenience in the unlatching of easily tore film 3, the edge of easily tore film 3 stretches out the edge of lid 1, is formed and easily tears structure 9.
In this utility model, lid 1 is set to 3 independent structures: plug chamber 5, tube for transfusion 6 and connecting tube 8, the design of this structure can be effectively increased structural strength, convenient use.And the diameter in plug chamber 5 is more than the diameter of tube for transfusion 6, it is simple to medical personnel's puncture procedure.Separately, the diameter of tube for transfusion 6 is slightly less than transfusion needle external diameter, and the frictional force before relying on transfusion needle and inside pipe wall effectively increases the size of plug 2 in plug chamber 5, can play the effect being effectively increased clamping transfusion needle stability.
The preparation method of a kind of one-body molded composite cover of this utility model, particularly as follows:
Special for body pellet and thermoplastic elastomer (TPE) plug pellet are placed in double material injection molding machine, substep injection: the first step, it is molded by lid with the special pellet of body, wherein, one section of temperature of injection machine is 190-210 DEG C, and two-stage nitration temperature is 200-220 DEG C, and three sections of temperature are 200-225 DEG C, head temperature 210-230 DEG C, injection pressure is 60-70MPa；
Second step, is directly molded by thermoplastic elastomer (TPE) plug with thermoplastic elastomer (TPE) plug pellet in the plug chamber of body, and wherein one section of temperature of injection machine is 150-180 DEG C, two-stage nitration temperature is 160-180 DEG C, three sections of temperature are 165-185 DEG C, head temperature 170-190 DEG C, and injection pressure is 55-65MPa.
3rd step, welds easily tore film 3.
The one-body molded composite cover of this utility model, it is possible to realize the several functions such as dosing and transfusion, its advantage is as follows:
1, by changing product design and processing technique, composite cover is formed in one, and eliminates the combinative structure that in prior art, the inner cap of composite cover, enclosing cover, plug etc. are complicated, the secondary pollution brought when decreasing fitment combination.
2, cleanliness factor is good, and safety is high.
3, technique is simple, and molding cycle is short, has higher cost advantage.
4, designed by simplification, it is not necessary to install pad retainer ring on plug top additional and can realize fixing of plug, and well clamp the effect of transfusion needle, reasonably reduce the production cost of product, embody energy-saving and cost-reducing, the design concept of environmental protection.
