Product structure, principle of action and methods of application

The structure of the blood backflow-preventive infusion set is shown in the right figure; The only difference between it and the traditional infusion set merely lies in the presence of a pressure gas balloon and buoyant plug in the Murphy's tube. Procedures of puncture, air inlet, air expelling, fluid conveyance and speed regulation in the entire operation course of the blood backflow-preventive infusion set are similar to that practiced in the ordinary disposable infusion set.

During infusion, when the fluid has entered into the Murphy's tube, with the buoyant plug up the fluid will flow through the infusion tube; When the fluid nearly flows to the end, the buoyant plug will fall down to have the outlet of the Murphy's tube completely blocked. Thus the space between the outlet of the Murphy's tube to its outlet will be filled with the fluid, and the fluid pressure in this pressure in this section of the tube will be higher then the venous blood pressure so as to stop the blood in the vessel to flow back.
When the fluid is to be changed, normal procedures are similar to that practiced with the traditional set.
If the buoyant plug does not float up, you can press the pressure gas balloon unit it floats up.
