Abstract
The utility model discloses a polypropylene infusion bag which comprises a neck opening, a bag body, a bag bottom and grooves on two sides of the bag body. The polypropylene infusion bag is characterized in that a wall of the bag body is recessed inward. The polypropylene infusion bag is good in self-contraction and overcomes the defect that an existing bag body has blood return or cannot exhaust infusion.
Description
Technical field
This utility model relates to a kind of transfusion bag, is specifically related to a kind of polypropylene self-priming transfusion bag, belongs to the medical packaging field.
Background technology
Along with the development of transfusion package technology, polypropylene infusion bag has become the main flow of infusion solutions packing.Polypropylene infusion bag utilizes the atmospheric pressure outside transfusion bag to shrink when transfusion, thereby makes medicinal liquid enter in patient's body, has avoided the existing outside air of traditional Open system to the shortcoming of liquid medicine contamination, is subject to clinical extensive use.
In existing document, publication number is that CN 2704376Y Chinese patent discloses a kind of polypropylene transfusion bottle, and its structure is made by flexible plastic, comprises a body, and be arranged on the bottleneck on this body top and be arranged on the bottle end of this body bottom, body is provided with guiding rib.The guiding rib structure is improved the self-constriction effect of bottle to a certain extent, but in actual use, because polypropylene material hardness is larger, self-constriction is not thorough in use, and medicinal liquid drips sordid phenomenon, thereby causes the generation of liquid waste or blood back phenomenon.
Summary of the invention
The technical problems to be solved in the utility model is that a kind of polypropylene infusion bag of self-constriction better effects if is provided.
Technical solution of the present utility model is, a kind of polypropylene infusion bag comprises the groove of eck, bag, the bag end and bag both sides it is characterized in that the bag body wall caves inward.
Wherein, described bag is flat, and the front of bag and the back side inwardly are the parabolic shape depression.
Under naturalness, the bag of flat effluxes in process at liquid, is subject to the pressure of ambient atmosphere, and the front that bag is wider and reverse side are mutually close, realizes effluxing of liquid.This utility model has increased on bag and inwardly has been the parabolic shape sunk structure, makes the front of bag and reverse side easier to be close, and contractive effect is followed.
The beneficial effect that this utility model has is: increased in design the body sunk structure, greatly increased the self-constriction effect of transfusion bag, when having avoided transfusion, medicinal liquid is from the generation of arranging thorough and blood back phenomenon.

Fig. 1 is this utility model side-looking structural representation;
Fig. 2 is this utility model bag cross-sectional structure schematic diagram;
In figure, 1, eck, 2, bag, 3, concave face, 4, groove, 5, the bag end.
The specific embodiment
For the technical solution of the utility model better is described, below in conjunction with accompanying drawing, the specific embodiment of the present utility model is carried out detailed description.
As shown in accompanying drawing 1 and Fig. 2, a kind of polypropylene infusion bag comprises the groove 4 of integrated eck 1, bag 2, the bag end 5 and bag both sides, and described bag front and back is concave face 3, inwardly is the parabolic shape depression.
In the above-described embodiments, a kind of preferred forms of this utility model is described, obviously, under inventive concept of the present utility model, still can make a lot of variations and transformation.
