All can use a large amount of disposable transfusion devices every day in the hospital, present disposable transfusion device comprises the air inlet pipe air filter, bottle plug puncture unit, drip kettle and injection needle, they have have once connected and composed infusion path by flexible pipe, be set with flow regulator on the flexible pipe, when patient uses the transfusion device of this routine once to need to input many bottles of liquid, whenever be totally lost one bottle and will change one bottle, and the time of changing bottle should be that time of just in time being totally lost at medicinal liquid, do not drip off if changed early medicinal liquid, just have the phenomenon of waste, if change late, will advance a lot of air in the infusion path, even blood back, advance in the pipeline to change bottle behind the air and also want aerofluxus, cumbersome.Because the patient who infuses in each hospital is often a lot; limited medical personnel can both be arrived in that of short duration moment that medicine just drips off at every turn; be difficult to realize, therefore use the transfusion device of this routine the phenomenons such as liquid waste, pipeline air inlet, blood back often can occur.

Summary of the invention

Problem to be solved in the utility model provides can delay time after a kind of medicinal liquid in infusion bottle drips off changes the transfusion device of liquid, and this transfusion device can effectively be prevented return blood, reduce the air capacity that enters pipeline after medicinal liquid drips off.

In order to address the above problem, the technical solution adopted in the utility model is: the batch (-type) transfusion device, be mainly used in the process aseptic process of venous transfusion, set up the Multichannel infusion set of passage between vein and the medicinal liquid, comprise the air inlet pipe air filter, bottle plug puncture unit, drip kettle and injection needle, they have connected and composed infusion pipeline successively by the PVC flexible pipe, be set with flow regulator on the flexible pipe, drip kettle and be provided with steam vent, it is characterized in that: described kettle is the Y-type three way type structure, drip on the kettle two branched pipes are arranged, 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 the PVC flexible pipe on described two branched pipes, bottle plug puncture unit and air inlet pipe air filter.

Further, the described interior check valve of kettle left-hand branch pipe comprises an annulus and a valve, 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 by the orifice flow of circle ring center, when the pressure below the valve during greater than top pressure, valve then can be pushed down the lower surface of annulus, blocks the aperture of circle ring center, and confined liquid upwards flows.

During use, what connect on the left-hand branch pipe with check valve is time infusion path, 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, saline bottle or glucose water bottle are inserted in the upper end of inferior infusion path, make the bottleneck height of medicine bottle be higher than the bottle end height of saline bottle or glucose water bottle during suspension, then will there be pressure differential between the two liquid roads, check valve in the inferior infusion path is subject to 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, saline or G/W enter main infusion path, continue transfusion, postponement a period of time changes dressings and also blood back can not occur, has also reduced the amount that air enters main infusion path simultaneously, change dressings like this time of bottle can have intermittently, and medical personnel can dilatoryly process one by one.

Compared with prior art, its advantage is, when many bottles of continuous transfusions of client need, if change dressings bottle time intermittently, postpone, the phenomenon of a lot of air also can not appear advancing in blood back and the infusion pipeline, also can reduce the waste of medicine; Medical personnel can tackle calmly a plurality of simultaneously patients of transfusion, thereby can reduce nursing staff's quantity, save 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.This utility model can be used for the upper all kinds of patients' of medical treatment disposable infusion.
