Further, described dress liquid charging stock is granular toughening modifying plastics.
The defect that the present invention has overcome conventional Shooting Technique and can not produce the medical soft bag of ratio of height to thickness, meets the requirement of product quality; Rational in infrastructure, easy to use, be finished rear volume contraction very little, easily process; Raw material cost performance is high, and cost declines.Especially the spue line of dress liquid is arranged on its thickness direction sidewall, can effective guarantee formed product, improve the ratio of briquetting of product, ensure product quality.
Brief description of the drawings
Fig. 1 is prior art structure chart;
Fig. 2 is structural representation of the present invention;
Fig. 3 is the upward view of Fig. 2.
Detailed description of the invention
Below, with reference to accompanying drawing, the present invention is more fully illustrated, shown in the drawings of exemplary embodiment of the present invention.But the present invention 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 the present invention comprehensively with complete, and scope of the present invention 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 side " " right side ", the relation for element shown in key diagram or feature with respect to another element or feature.It should be understood that except the orientation shown in figure, spatial terminology is intended to comprise the different azimuth of device in using or operating.For example, if the device in figure is squeezed, be stated as the element that is positioned at other elements or feature D score will be positioned at other elements or feature " on ".Therefore, exemplary term D score can comprise upper and lower orientation both.Device can otherwise be located (90-degree rotation or be positioned at other orientation), and the relative explanation in space used here can correspondingly be explained.
As shown in Figure 2 and Figure 3, a kind of self-contraction transfusion bottle of the present invention or transfusion bag, comprise dress liquid 3, dress liquid 3 is flat structure under the state of filling medicinal liquid, on the cross section perpendicular to port and afterbody line, the width 7 of dress liquid is greater than thickness 6, and dress liquid 1 is processed into by left and right two parts matched moulds, the thickness direction plane of symmetry that its spue line 5 is dress liquid 1 and the intersection of dress hydraulic fluid side wall.Flat structure is made up of two main surfaces 1, and the lateral edges of two main surfaces 1 is connected by surface blending 2.
Self-contraction transfusion bottle of the present invention or transfusion bag, the width 7 that is aimed at dress liquid 3 is more than or equal to 3 situation with the ratio of thickness 6, but the width 7 of dress liquid 3 is less than at 3 o'clock with the ratio of thickness 6, also can adopt said structure form.
The invention solves conventional Shooting Technique and can not produce the defect of the medical soft bag of ratio of height to thickness.Due to after the width 7 of dress liquid 3 is more than or equal to 3 with the ratio of thickness 6, side wall surface lack of homogeneity, thickness of two sides difference is large, and cooling water channel cannot be set in bottle blowing mould manufacturing process herein, cannot effective guarantee formed product.
In the present invention, the manufacture method of above-mentioned self-contraction transfusion bottle or transfusion bag, for two step method is noted, drawn, blow moulding, this two step method is noted, is drawn, blow moulding process is:
1) fill liquid medical plastic preparation of raw material;
2) the medical plastic raw material of preparing mixes;
3) medical plastic raw material after mixing is made to the base type that fills liquid by injection machine injection moulding;
4) the base type of made dress liquid place or under protective condition, force cooling make it to solidify stable;
5) the base type that solidifies the dress liquid after stablizing is sent into bottle blowing machine blow molding, obtain finished product, wherein the spue line of the left and right mould of bottle blowing machine is arranged on the thickness direction of dress liquid;
6) will fill liquid end product packing and storing.
In the present invention, concrete technology step is:
1, granular toughening modifying plastic warp auxiliary facilities (as Material sucking machine) is input in injecting machine material tube, injecting molding mold cavity in barrel after heating and melting, pressurize cooling forming blocker processed.
2, base type is placed cooling curing or is adopted the cooling mode of pressure to send into bottle blowing machine under purify protect and heats, and blowing becomes transfusion bag or infusion bottle, and the biaxial tension blowing mode that blowing mode adopts is carried out bottle blowing.(the conceptual understanding explanation of biaxial tension blowing mode: the base type after heating adopts the mechanical force of blowing machine stretching bar to implement longitudinal stretching in blow mold; Simultaneously or carry out cross directional stretch with the compressed air of 1.8～2.5Mpa pressure limit after a while)
3, infusion bottle or transfusion bag enter and under high temperature, carry out sterilizing after wash bottle, liquid drug, capping.
The temperature of its sterilizing and sizing generally can adopt 115 DEG C, or 118 DEG C, or 121 DEG C, meet the regulation of national standard and can obtain best medicinal liquid sterilizing and the effect of transfusion flexible bag sizing.
Dress liquid of the present invention 1 is for note, draw, blow an entirety of formation, and dress liquid 1 can form port, cervical region etc. accordingly, and it does not have joint face, does not need to carry out high temperature hot pressing plastic packaging, also just there will not be edge plastic packaging leakiness and the situation of leakage occurs.Infusion bottle of the present invention or transfusion bag are flexible body, and it does not adopt vent line, do not have the pollution problem of return-air to medicinal liquid; Flat flat when transfusion finishes, medicinal liquid drains completely, does not produce venous blood blood back phenomenon, improves infusion safety, can obtain the effect of best medicinal liquid sterilizing and transfusion flexible bag sizing.Processing technique advanced person of the present invention, the defect that has overcome conventional Shooting Technique and can not produce the medical soft bag of ratio of height to thickness, meets the requirement of product quality, rational in infrastructure, easy to use, is finished rear volume contraction very little, easily processes, and raw material cost performance is high, and cost declines.Especially the spue line of dress liquid is arranged on its thickness direction sidewall, by this technological improvement, has solved the problem that the transfusion flexible bag recorded in background technology exists, the present invention can effective guarantee formed product, improves the ratio of briquetting of product, has ensured product quality.
