Abstract
The invention provides an anti-countercurrent injection part. The anti-countercurrent injection part comprises a Y-shaped catheter main body, wherein the lower part of the Y-shaped catheter main body is provided with a connector matched with an infusion tube, a rubber plug cap is arranged on one of branch pipes at the upper part of the Y-shaped catheter main body, a valve cavity is formed in the other branch pipe, a liquid outlet communicated with the branch pipe is formed at the lower part of the valve cavity, the upper part of the valve cavity is provided with a pipeline connector with an infusion channel, a silica gel membrane matched with the infusion channel is arranged in the valve cavity, and a plurality of support pillars for supporting the silica gel membrane are arranged at the periphery of the liquid outlet; and the connector comprises a connecting inner pipe arranged in the Y-shaped catheter main body in a sleeving manner, the top end of the connecting inner pipe is connected to the inner wall of the Y-shaped catheter main body, and a clamping groove for fixing an infusion hose is formed between the connecting inner pipe and the Y-shaped catheter main body. The anti-countercurrent injection part is reasonable in design and convenient to operate, facilitates the injection of medicines and meanwhile avoids the countercurrent phenomenon.
Description
Technical field
The present invention relates to a kind of area of medical devices, particularly a kind of counterflow-preventing injection member.
Background technology
At present, the injection member of using clinically only has single function of injection, and medicinal liquid enters after tube for transfusion by injection member, easily upwards flow under pressure, for the patient who needs fast injection medicinal liquid, as there is the patient of infusion reaction and the patient of first aid, wasted rescue time.Before, nurse's common practice is to disconnect being connected of transfusion catheter and intravenous needle, from the quiet medicine that pushes away of intravenous needle flexible pipe, when this way has not only been wasted time but also intravenous needle flexible pipe and is again connected with transfusion catheter, easily produces bubble.
Summary of the invention
Technical problem to be solved by this invention is for the deficiencies in the prior art, provides a kind of reasonable in design, and injection is convenient, can prevent the counterflow-preventing injection member of medicine adverse current.
Technical problem to be solved by this invention is to realize by following technical scheme, the present invention is a kind of counterflow-preventing injection member, be characterized in: comprise Y shape catheter main body, the bottom of Y shape catheter main body is provided with the union joint coordinating with tube for transfusion, one of them arm on Y shape catheter main body top is provided with plug block, another arm is provided with valve pocket, the bottom of valve pocket is provided with the liquid outlet being communicated with arm, the top of valve pocket is provided with the pipe joint with infusion channel, in valve pocket, be provided with the gel silica membrane coordinating with above-mentioned infusion channel, on the periphery of liquid outlet, be provided with the some support columns that support gel silica membrane, described union joint comprises the connection inner tube being set in Y shape catheter main body, connects the top of inner tube and the inwall of Y shape catheter main body and joins, and connects between inner tube and Y shape catheter main body and is provided with the fixedly draw-in groove of infusion tube.
The present invention is contained in transfusion catheter, when needs fast injection medicinal liquid, by the entry needle plug that punctures, block a shot, medicine can be added fast, gel silica membrane in another arm valve pocket has the effect of check valve simultaneously, when the plug block from another arm during injectable drug, can prevent medicine adverse current, make medicine enter human body with prestissimo, for giving emergency treatment to a patient the time of having saved, compared with prior art, it is reasonable in design, simple to operate, when facilitating injectable drug, there will not be again the phenomenon of adverse current.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present invention.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present invention, so that those skilled in the art understands the present invention further, and do not form the restriction to its right.
With reference to Fig. 1, a kind of counterflow-preventing injection member, comprise Y shape catheter main body 1, the bottom of Y shape catheter main body 1 is provided with the union joint coordinating with tube for transfusion, described union joint comprises the connection inner tube 2 being set in Y shape catheter main body 1, connect the top of inner tube 2 and the inwall of Y shape catheter main body 1 and join, connect between inner tube 2 and Y shape catheter main body 1 and be provided with the fixedly draw-in groove of infusion tube.
One of them arm on Y shape catheter main body 1 top is provided with plug block 3, quiet while pushing away medicine fast when needs, does not need to disconnect being connected of transfusion catheter and intravenous needle, can be blocked a shot and 3 is carried out dosing by the entry needle plug that punctures.Another arm is provided with valve pocket 5, the bottom of valve pocket 5 is provided with the liquid outlet being communicated with arm, the top of valve pocket 5 is provided with the pipe joint with infusion channel, in valve pocket 5, be provided with the gel silica membrane 6 coordinating with above-mentioned infusion channel, on the periphery of liquid outlet, be provided with the some support columns 4 that support gel silica membrane 6.During use, during liquid positive flow, medicinal liquid promotes gel silica membrane 6 and moves down the infusion channel of leaving valve pocket 5 tops, and the rear supported post 4 of gel silica membrane 6 is held, and medicinal liquid flows out from entering the liquid outlet of valve pocket 5 bottoms between support column 4.When liquid countercurrent, under fluid pressure effect, gel silica membrane 6 is upwards blocked the infusion channel on valve pocket 5 tops, thereby stops liquid countercurrent.
Claims (1)
