Abstract
The utility model provides a waste liquid bag which comprises an upper conduit, a lower conduit and an air filtration hole which is arranged on the waste liquid bag. The air filtration hole is arranged at the upper part of the waste liquid bag and close to the upper conduit. The air filtration hole is internally provided with a filtration medium. The filtration medium is an acetate fiber filtration bar. The waste liquid bag can avoid waste liquid backflow to pollute the blood so as to ensure the safe operation of the entire blood salvage process.
Description
Technical field
This utility model relates to field of medical, relates in particular to a kind of waste fluid bag that the autoblood recovery system is used that is used for.
Background technology
In present operative treatment, the phenomenon of often bleeding profusely runs off for fear of the blood of preciousness in vain, adopts the blood retracting device usually, after patients'blood is handled, re-enters in the patient body again.In autoblood reclaims application, blood is through a series of processing, producing a part of waste liquid simultaneously; Can obtain pure fresh blood; This part usually is recovered in the blood bag, and in order to patient's infusion, the waste liquid of generation then is collected in the waste fluid bag.Because the blood bag is connected on pipeline with waste fluid bag,, cause the erythrocytic pollution of last recovery so in removal process, may cause in a part of waste liquid backflow and the inflow blood bag.For the case of massive hemorrhage, the failure of a blood recovery may directly be directed at and jeopardize patient's life.
The utility model content
The purpose of this utility model embodiment is to provide a kind of waste fluid bag, and this waste fluid bag comprises upper conduit and downcomer, also comprises: the air filtration hole is arranged on the said waste fluid bag.
Said air filtration hole is arranged at the top of said waste fluid bag, closes on said upper conduit.
Said air filtration is provided with filter medium in the hole.
Said filter medium is the acetate fiber filter stick.
The waste fluid bag of this utility model can be avoided waste liquid backflow pollution blood, thereby guarantees the safe operation of whole blood removal process.
Description of drawings
Accompanying drawing described herein is used to provide the further understanding to this utility model, constitutes the application's a part, does not constitute the qualification to this utility model.In the accompanying drawings:
Fig. 1 is the structural representation of this utility model waste fluid bag;
Fig. 2 is the sketch map that this utility model waste fluid bag is used for the blood recovery system.
The specific embodiment
For the purpose, technical scheme and the advantage that make this utility model embodiment is clearer, below in conjunction with embodiment and accompanying drawing, embodiment explains further details to this utility model.At this, illustrative examples of this utility model and explanation thereof are used to explain this utility model, but not as the qualification to this utility model.
Embodiment one
See also Fig. 1, Fig. 1 is the structural representation of this utility model waste fluid bag, and is as shown in the figure, and the waste fluid bag of this utility model, this waste fluid bag comprise upper conduit 110 and downcomer 120, and also comprise: air filtration hole 130 is arranged on the said waste fluid bag.
Generally; Upper conduit 110 is arranged on the top of waste fluid bag, and downcomer 120 is arranged on the bottom of waste fluid bag, is that waste liquid flows into and discharges for ease; Simultaneously in case the waste liquid backflow; Described air filtration hole 130 is arranged at the top of said waste fluid bag, closes on said upper conduit 110, is the upper space of the waste fluid bag of air inflow for ease like this.In order air filtration also to be provided with filter medium in said air filtration hole 130, in the present embodiment, this filter medium adopts the acetate fiber filter stick.But be not limited to this, as long as can realize the function of this utility model filtered air, those skilled in the art can adopt other filter mediums, all should be included in this utility model protection domain.
See also Fig. 2 again, Fig. 2 is the sketch map that this utility model waste fluid bag is used for the blood recovery system, and in the process that autoblood reclaims, the former blood of collection is recycled into the blood bag after treatment, between the waste liquid that produces then flow into waste fluid bags through upper conduit 110.Whole system is under an airtight environment, to carry out.For some reason, in the process of the blood re-injection blood bag after processing, the waste liquid of waste fluid bag is back in the blood processing system, even flow in the blood bag, causes the pollution of blood, causes the failure of recovery.The waste fluid bag that this utility model embodiment provides has increased an air filtration hole 130 at its top; When blood is recycled into from processing system in the process of blood bag; Have through filtering filtrated air and get into waste fluid bag; When fortuitous event occurring, filtrated air replaces waste liquid to get into blood processing system.Owing to be through filtering filtrated air, so can guarantee that blood is not contaminated.
The waste fluid bag that this utility model provides can be avoided waste liquid backflow pollution blood, thereby guarantees the safe operation of whole blood removal process.
Above-described specific embodiment; Purpose, technical scheme and beneficial effect to this utility model have carried out further explain, it should be understood that the above is merely the specific embodiment of this utility model; And be not used in the protection domain that limits this utility model; All within the spirit and principle of this utility model, any modification of being made, be equal to replacement, improvement etc., all should be included within the protection domain of this utility model.
