Description

A kind of from discharge opeing internal enclosed transfusion bag

Technical field

This utility model relates to a kind of transfusion bag, more particularly, relates in particular to a kind of from discharge opeing internal enclosed transfusion bag.

Background technology

At present, in pharmaceuticals industry, transfusion package mainly contains vial, plastic bottle, soft bag etc.Vial is comparatively traditional a kind of infusion vessel, its bottle cap is mainly made up of the outer sheathed aluminium-plastic cap of Plastic bottle plug, easily produces bits material when liquid is drawn in transfusion device puncture, affects quality of liquid medicine, and the defect such as pollution probability height for the second time, health is had to potential hidden danger, and vial body weight is large, and cost of transportation is high, collision in transportation easily causes stealthy laceration, cause drug contamination, and aluminium-plastic cap cost is high, is progressively eliminated now.Plastic infusion bottle is a kind of emerging infusion vessel product, but plastic infusion bottle is not from draining function, in clinical use procedure, still palpiform becomes air loop medicinal liquid just can ooze, airborne microgranule, antibacterial still can enter medicinal liquid by air loop, the probability of secondary pollution is still higher, and the harm potential to health still exists.Soft bag is current up-to-date infusion vessel, when transfusion, need not form air loop and just medicinal liquid can be oozed, greatly reduce the probability of secondary pollution in medicine use procedure, and no matter after still using in process of production, all little to the pollution of environment, use safety, environmental protection.

How a kind of transfusion bag having from draining function is provided, to provide safer transfusion package to select, becomes those skilled in the art's problem demanding prompt solution.

Utility model content

The purpose of this utility model is for above-mentioned the deficiencies in the prior art, provide a kind of rational in infrastructure, liquid storage amount is large and easy to use from discharge opeing internal enclosed transfusion bag.

The technical solution of the utility model is achieved in that a kind of from discharge opeing internal enclosed transfusion bag, comprise soft bag, one-body molded in the bag neck upper end on bag top have a diaphragm seal, and wherein said bag is held with it by bag body, connecting bag and the taper connection portion of bag neck and the support bottom surface that is arranged on bag body lower end form; The contact site of bag body and taper connection portion is rounding off structure; The cross section of described bag body is by two sections of parallel straightways and be connected to two sections of segmental arcs between straightway two ends and form, and is rounding off connection between straightway and segmental arc; Gap ratio between spacing between two sections of straightways and two sections of segmental arc centers is 1:1.5～3.

Above-mentioned one is in discharge opeing internal enclosed transfusion bag, and it is on 0.75～0.92 ellipse that two sections of segmental arcs are positioned at eccentricity.

Above-mentioned one is in discharge opeing internal enclosed transfusion bag, and described bag body thickness is 0.25～0.35mm; The thickness of described taper connection portion and support bottom surface is 0.4～0.5mm.

Above-mentioned one, in discharge opeing internal enclosed transfusion bag, is vertically provided with reinforcement two sections of bag body positions corresponding to straightway, and the thickness of described reinforcement is 0.4～0.5mm, and described reinforcement connects respectively taper connection portion and supports bottom surface.

Above-mentioned one is in discharge opeing internal enclosed transfusion bag, and on described support bottom surface, along being circumferentially with four support rims, one-body molded on the support bottom surface of support rim inner side have suspension ring, and the thickness of suspension ring is less than the height of support rim.

This utility model adopts after said structure, is first the bag body structure that straightway adds segmental arc by adopting cross section, and bag can be extruded under less pressure, substantially can solve the object from discharge opeing.Then, then in conjunction with preferred segmental arc and preferred bag body thickness, make transfusion bag from discharge opeing better effects if; Further, for making bag body can not occur easily crooked situation, in bag body both sides, reinforcement is set, effectively improve the intensity of transfusion bag but do not affect the effect from discharge opeing, meanwhile, then in conjunction with supporting support rim and the suspension ring of bottom surface, make the transfusion bag both can be upright, instant packed, dosing, convenient suspention is used again.This utility model is easy and simple to handle, safe and reliable, environmental protection and cost lower, be worthy to be popularized.

Brief description of the drawings

Below in conjunction with the embodiment in accompanying drawing, the utility model is described in further detail, but do not form any restriction of the present utility model.

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the sectional structure schematic diagram at A～A place in Fig. 1.

In figure: bag 1, bag body 1a, the 1b of taper connection portion, support bottom surface 1c, straightway 1d, segmental arc 1e, bag neck 2, diaphragm seal 3, reinforcement 4, support rim 5, suspension ring 6.

Detailed description of the invention

Consult shown in Fig. 1 to Fig. 2, one of the present utility model, from discharge opeing internal enclosed transfusion bag, comprises soft bag 1, and bag 1 preferably adopts polypropylene material to make.One-body molded in bag neck 2 upper ends on bag 1 top have a diaphragm seal 3, and described bag 1 is made up of the 1b of taper connection portion of bag body 1a, connecting bag body 1a upper end and bag neck 2 and the support bottom surface 1c that is arranged on bag body 1a lower end, and bag body 1a thickness is 0.25～0.35mm; The thickness of the described taper connection 1b of portion and support bottom surface 1c is 0.4～0.5mm; The contact site of bag body 1a and the 1b of taper connection portion is rounding off structure; Supporting on the 1c of bottom surface along being circumferentially with four support rims 5, one-body molded on the 1c of the support bottom surface of support rim 5 inner sides have suspension ring 6 simultaneously, and the thickness of suspension ring 6 is less than the height of support rim 5.Adopt the upper and lower two ends of intermediate thin thick structures, not only convenient from discharge opeing but also can strengthen the bulk strength of transfusion bag, then coordinate support rim 5, make upright place convenient.The cross section of described bag body 1a is by two sections of parallel straightway 1d and be connected to two sections of segmental arc 1e between straightway 1d two ends and form, and is rounding off connection between straightway 1d and segmental arc 1e; Gap ratio between spacing between two sections of straightway 1d and two sections of segmental arc 1e centers is 1:1.5～3; It is on 0.75～0.92 ellipse that two sections of segmental arc 1e are positioned at eccentricity.This transfusion bag just can be oozed naturally without forming air loop medicinal liquid, realized from draining function, thereby the probability of reduction medicinal liquid secondary pollution uses safer.

Further, be vertically provided with reinforcement 4 two sections of bag body 1a positions corresponding to straightway 1d, the thickness of described reinforcement 4 is 0.4～0.5mm, is the gross thickness of reinforcement 4 positions; Described reinforcement 4 connects respectively the 1b of taper connection portion and supports bottom surface 1c.Reinforcement 4 plays to be strengthened when vertical intensity, do not affect transfusion bag from discharge opeing effect.

Above illustrated embodiment is preferred embodiments of the present utility model, only be used for facilitating explanation this utility model, not this utility model is done to any pro forma restriction, under any, in technical field, have and conventionally know the knowledgeable, if not departing from the scope of technical characterictic that this utility model is carried, utilize technology contents that this utility model discloses to do the local equivalent embodiment that changes or modify, and do not depart from technical characterictic content of the present utility model, all still belong in the scope of this utility model technical characterictic.
