Summary of the invention
The problem that the present invention will solve provides can delay time after a kind of medicinal liquid in the transfusion medicine bottle drips off changes the transfusion device of liquid, and this transfusion device can effectively prevent blood back, reduce the air capacity that gets into pipeline after medicinal liquid drips off.
In order to address the above problem, the technical scheme that the present invention adopts is: the batch (-type) transfusion device, be mainly used in venous transfusion the process aseptic process, set up the multi-path transfusion device of passage between vein and the medicinal liquid; Comprise air inlet pipe air filter, bottle plug puncture unit, drip kettle and injection needle, they have connected and composed infusion pipeline successively through the PVC flexible pipe, are set with flow regulator on the flexible pipe; Drip kettle and be provided with steam vent, it is characterized in that: said kettle is the Y-type three way type structure, and dripping on the kettle has two branched pipes; On connect two infusion paths; Be provided with a dropper in each branched pipe, also be provided with a check valve in the branched pipe in left side, check valve makes the liquid can only be to dirty; Can not reflux, all connect PVC flexible pipe, bottle plug puncture unit and air inlet pipe air filter on said two branched pipes.
Further, the said interior check valve of kettle left-hand branch pipe comprises an annulus and a valve, and annulus is fixed on the inwall of branched pipe; One side of valve stick on annulus below, opposite side can freely swing with fluid pressure, when the pressure above the valve during greater than following pressure; One side of valve is sagging; Liquid can go down through the orifice flow of circle ring center, and when the pressure below the valve during greater than top pressure, valve then can be pushed down the lower surface of annulus; Block the aperture of circle ring center, confined liquid upwards flows.
During use, having what connect on the left-hand branch pipe of check valve is time infusion path, and what do not have to connect on the right-hand branch pipe of check valve is main infusion path; The medicine bottle of transfusion is inserted in main infusion path upper end, and saline bottle or glucose water bottle are inserted in the upper end of inferior infusion path, makes the bottleneck height of medicine bottle be higher than the bottle end height of saline bottle or glucose water bottle during suspension; Then will have pressure differential between the two liquid roads, the check valve in the inferior infusion path receives the pressure of autonomous infusion path greater than the pressure that produces on the inferior infusion path, when in the medicine bottle liquid medicine being arranged; Check valve is in closed condition all the time, after the medicinal liquid in the medicine bottle on the main infusion path drips off, if medical personnel can not arrive in the very nick of time; Then time infusion path will be opened automatically, and saline or G/W get into main infusion path, continue transfusion; Postponement a period of time changes dressings and also blood back can not occur; Also reduced simultaneously the amount of air admission master infusion path, the time of the bottle of changing dressings like this can have intermittently, and medical personnel can dilatoryly handle one by one.
Compared with prior art, its advantage is, when patient needs many bottles continuously during transfusion, if change dressings bottle time intermittently, postpone, the phenomenon of a lot of air can not appear advancing in blood back and the infusion pipeline yet, also can reduce the waste of medicine; Medical personnel can tackle a plurality of patients of transfusion simultaneously calmly, thereby can reduce nursing staff's quantity, practice thrift the human resources; Inferior infusion path can play the effect of washing away main infusion path after main infusion path drips off, avoid the pharmacological reaction between the different pharmaceutical.The present invention can be used for the disposable infusion that all kinds of patients are gone up in medical treatment.
