Description
Technical field
This utility model relates to transfusion bag, particularly a kind of single tube polypropylene infusion bag with Pop-top seal cap.
Background technology
Venous transfusion mode goes through three changes: from full open model to semi open model, arrive total closed type again, there has been the transfusion bag of a large amount of total closed types, but when clinical treating disease, require that transfusion bag can uprightly be placed, 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.
The puncture reliability of existing transfusion bag is poor, due to the misoperation of medical personnel, easily puncture transfusion bag, cause infusing unsuccessfully, even occur security incident, in addition, the sealing property of composite cover transfusion bag is bad, easily before and after transfusion, occurs the phenomenon of leakage, and in order to prevent medicinal liquid from refluxing, patient under normal circumstances can not arbitrarily movement, and this makes troubles to patient.
Utility model content
The purpose of this utility model is the shortcoming overcoming prior art, provides a kind of and improves puncture reliability, good airproof performance, the anti-pollution and single tube polypropylene infusion bag with Pop-top seal cap that prevents medicinal liquid from flowing backwards.
The purpose of this utility model is achieved through the following technical solutions: a kind of single tube polypropylene infusion bag with Pop-top seal cap, it comprises transfusion bag body and is arranged on the hanging hole of transfusion bag body bottom portion, it also comprises mouthpiece assembly, check valve and draw ring easy to break, described mouthpiece assembly comprises top tube and down tube, the upper end outer wall of lower pipe and the lower end inner wall of upper pipe are connected, bottom outer wall and the transfusion bag body of lower pipe are tightly connected, and lower pipe is communicated with transfusion bag body interior, the lower end of lower pipe is connected with Taper Pipe, Taper Pipe is positioned at transfusion bag body, the upper surface of lower pipe is pasted with easily stings film, coordinate in upper pipe above easy thorn film and guiding plug is installed, the mouth of pipe place of upper pipe is also provided with check valve, described draw ring easy to break is arranged at the center, upper surface of check valve.
The medial wall of described upper pipe is provided with pipe bulge loop, and the lateral wall of guiding plug is provided with the plug groove that can coordinate with upper pipe bulge loop, and during assembling, upper pipe bulge loop is stuck in plug groove.
The center of both ends of the surface up and down of described guiding plug is respectively arranged with the depressed part extended towards its center of gravity.
The lateral wall of described lower pipe is provided with lower pipe bulge loop, and the medial wall of upper pipe is provided with the upper pipe groove that can coordinate with lower pipe bulge loop, during assembling, lower pipe bulge loop is stuck in pipe groove.
This utility model has the following advantages:
1, when medical personnel puncture, puncture needle thrusts guiding plug, under the guide effect of depressed part through check valve, syringe needle slides to depressed part center, carries out first time guiding, and two-side recess portion makes the center of guiding plug weaker, thrust difficulty to reduce, after puncturing guiding plug, enter lower pipe, the lower end of lower pipe connects Taper Pipe, carry out second time guiding, guarantee that puncture needle is positioned on the axis of lower pipe all the time, after guaranteeing to thrust, can not transfusion bag be punctured, improve the reliability of puncture procedure.
2, in the upper surface of lower pipe, stickup easily stings film, and after dress liquid, easily medicinal liquid is isolated from the outside by thorn film, prevents medicinal liquid contaminated; After puncturing, guiding plug is under the squeezing action of check valve, and no matter fit with upper inside pipe wall, add pipe bulge loop and plug groove fit, formed multiple-sealed, be before transfusion or in infusion process, its good sealing effect.
3, arrange check valve at upper pipe mouth of pipe place, prevent medicinal liquid from refluxing, patient arbitrarily can walk about in infusion process.
