Abstract
The utility model provides an infusion set injection element which comprises a Y-type catheter body. The lower portion of the Y-type catheter body is provided with a Lure fitting matched with a vein infusion needle base and provided with inner threads, one branch on the upper portion of the Y-type catheter body is provided with a rubber plug cap, and the other branch of the Y-type catheter body is provided with a one-way valve. The Lure fitting can be directly connected with the vein infusion needle base, so that one catheter can be omitted, the time for medicine entering a human body is shortened, meanwhile assembly procedures of an infusion set can be reduced, and production efficiency is improved. Besides, when medicine is injected into the rubber plug cap of one branch, the one-way valve on the other branch can prevent the medicine from refluxing, and accordingly the medicine can enter the human body at the highest speed.
Description
Technical field
This utility model relates to a kind of area of medical devices, particularly a kind of transfusion device injection member.
Background technology
At present, the injection member 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.In present transfusion device, between injection member and intravenous needle conduit, have one end tube for transfusion in addition, therefore when dosing, it is long that medicinal liquid enters time of human body, and transfusion device installation step is many, and production efficiency is low.
Summary of the invention
Technical problem to be solved in the utility model is for the deficiencies in the prior art, and a kind of transfusion device injection member reasonable in design, convenient for production is provided.
Technical problem to be solved in the utility model is to realize by following technical scheme, this utility model is a kind of transfusion device injection member, be characterized in: comprise Y shape catheter main body, the bottom of Y shape catheter main body be provided with venous transfusion needle stand coordinate, tapped female Luer, one of them arm on Y shape catheter main body top is provided with plug block, and another arm is provided with check valve.
Technical problem to be solved in the utility model can also further realize by following technical scheme, described check valve comprises the valve pocket being located on arm, 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.
Compared with prior art, female Luer of the present utility model can directly be joined with venous transfusion needle stand, can save like this one section of conduit, shorten the time that medicine enters human body, can reduce the step of transfusion device assembling simultaneously, enhance productivity, in addition in the time of injectable drug from the plug block of one of them arm, check valve on another arm, can prevent medicine adverse current, makes medicine enter human body with prestissimo.
Accompanying drawing explanation
Fig. 1 is a kind of structural representation of the present utility model.
The specific embodiment
Referring to accompanying drawing, further describe concrete technical scheme of the present utility model, 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 transfusion device injection member, comprise Y shape catheter main body 1, the bottom of Y shape catheter main body 1 be provided with venous transfusion needle stand coordinate, tapped female Luer 2, one of them arm on Y shape catheter main body 1 top is provided with plug block 3, fast quiet while pushing away medicine when needs, do not need to disconnect being connected of transfusion catheter and intravenous needle, can block a shot and 3 carry out dosing by the entry needle plug that punctures.
Another arm is provided with check valve, described check valve comprises the valve pocket 5 being located on arm, 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.When use, when 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 the liquid outlet that enters valve pocket 5 bottoms between support column 4.In the time of 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 (2)
1. a transfusion device injection member, it is characterized in that: comprise Y shape catheter main body, the bottom of Y shape catheter main body be provided with venous transfusion needle stand coordinate, tapped female Luer, one of them arm on Y shape catheter main body top is provided with plug block, and another arm is provided with check valve.
2. transfusion device injection member according to claim 1, it is characterized in that: described check valve comprises the valve pocket being located on arm, 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.
