Description

Portable reverse-filling polypropylene infusion bag

Technical field

This utility model relates to transfusion bag, particularly portable reverse-filling polypropylene infusion bag.

Background technology

Transfusion is a kind of conventional medical procedure, clinically for keeping the skin wet to patient, energy and input medicine, can fast and effeciently alleviate and cure the state of an illness.At present, the infusion model of clinical practice mainly adopts transfusion bag or infusion bottle to give patient conventional infusion.Venous transfusion mode goes through three changes: from full open model to semi open model, then to total closed type, there has been the transfusion bag of a large amount of total closed types, but when clinical treating disease, require transfusion bag energy convenient pin, puncturing hole cleanliness factor is high.Realize above requirement, then need jointly to improve the composite cover of transfusion bag and sealing transfusion bag.

At present, most patient can not arbitrarily movement in infusion process, and its reason prevents medicinal liquid from refluxing, and when patient will walk about or go to toilet, needs transfusion bag to elevate, just can reach the object preventing medicinal liquid from refluxing, bring larger inconvenience to patient.

Utility model content

The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of and portablely feels comfortable, backflow phenomenon does not appear in medicinal liquid and can prevent the contaminated portable reverse-filling polypropylene infusion bag of medicinal liquid.

The purpose of this utility model is achieved through the following technical solutions: portable reverse-filling polypropylene infusion bag, comprise transfusion bag body, tailgate and drain pipe, tailgate is arranged at the afterbody of transfusion bag body, drain pipe is arranged at the head centre position of transfusion bag body, and drain pipe is communicated with transfusion bag body interior, the lower end port of drain pipe posts sealing pad pasting, tailgate is provided with grip part and hanging hole, hanging hole is arranged at the top of grip part; Reverse-filling mechanism is also provided with in drain pipe, described reverse-filling mechanism comprises drain post and non-return plug, drain post is the tub structure that top has opening, and the sidewall of drain post offers multiple fluid seam in the axial direction, and non-return plug is slidably installed in drain post.

The top of described drain pipe is cone structure, and upper port edge and the described cone structure of drain post are tightly connected, and drain post is coaxial with drain pipe.

The upper surface of described non-return plug is provided with non-return, and non-return is the surface consistent with described cone structure.

Described grip part is waveform cambered surface, and edge's rounding.

This utility model has the following advantages:

1, on tailgate, be provided with grip part, and grip part is set to waveform globoidal structure according to human engineering, edge rounding, when patient or family members mention transfusion bag by grip part, feels more comfortable, be conducive to the emotion improving patient, promote that the state of an illness is recovered.

2, in drain pipe, arrange reverse-filling mechanism, when medicinal liquid has the trend of backflow, non-return plug is under the effect of self gravitation with backflow medicinal liquid, conical surface mechanism to drain pipe moves, until block the drain pipe mouth of pipe, thus prevent medicinal liquid from refluxing, bring great convenience to patient and family members.

3, on the lower end port of drain pipe, post sealing pad pasting, realize the front isolation pocket inner liquid medicine of transfusion, prevent medicinal liquid by outside contamination.

Accompanying drawing explanation

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

Fig. 2 is the internal structure schematic diagram of drain pipe;

Fig. 3 is A-A sectional structure schematic diagram in Fig. 2;

In figure: 1-transfusion bag body, 2-tailgate, 3-drain pipe, 4-seals pad pasting, 5-grip part, 6-hanging hole, 7-drain post, the non-return plug of 8-, and 9-fluid is stitched, non-return of 10-.

Detailed description of the invention

Below in conjunction with accompanying drawing, this utility model is further described, but protection domain of the present utility model is not limited to the following stated.

As shown in Figure 1, portable reverse-filling polypropylene infusion bag, comprise transfusion bag body 1, tailgate 2 and drain pipe 3, tailgate 2 is arranged at the afterbody of transfusion bag body 1, drain pipe 3 is arranged at the head centre position of transfusion bag body 1, and drain pipe 3 is communicated with transfusion bag body 1 inside, the lower end port of drain pipe 3 posts sealing pad pasting 4, tailgate 2 is provided with grip part 5 and hanging hole 6, hanging hole 5 is arranged at the top of grip part 5; As shown in Figures 2 and 3, reverse-filling mechanism is also provided with in drain pipe 3, described reverse-filling mechanism comprises drain post 7 and non-return plug 8, drain post 7 has the tub structure of opening for top, the sidewall of drain post 7 offers multiple fluid seam 9 in the axial direction, and non-return plug 8 is slidably installed in drain post 7.

Further, as shown in Figure 2, the top of described drain pipe 3 is cone structure, and upper port edge and the described cone structure of drain post 7 are tightly connected, and drain post 7 is coaxial with drain pipe 3.

Further, as shown in Figure 3, the upper surface of described non-return plug 8 is provided with non-return face 10, and non-return face 10 is the surface consistent with described cone structure.

Further, as shown in Figure 1, described grip part 5 is waveform cambered surface, and edge's rounding.

Work process of the present utility model is as follows: when patient infuses on one's sick bed, transfusion bag body 1 is hung on drip stand, tear sealing pad pasting 4, tube for transfusion puncture needle is thrust in drain pipe 3, be communicated with transfusion bag body 1 inner liquid medicine, carry out normal infusion, when client need moves, transfusion bag body 1 can be taken off, grasp grip part 5, when medicinal liquid has the trend of backflow, non-return plug 8 is under the effect of self gravitation with backflow medicinal liquid, conical surface mechanism to drain pipe 3 moves, until block drain pipe 3 mouth of pipe, thus prevent medicinal liquid from refluxing, bring great convenience to patient and family members.
