The utlity model has following advantage:
1, this utility model has increased the pressure-reducing cushioning device on the basis of original " oxygenation transfusion device ", the amount of oxygen that guarantees input when making clinical use consistently, manual dexterity, safe ready.
But 2, harmful insoluble microparticle and pyrogen in Shu Ye the high efficiency particulate air filter absorption medicinal liquid, remaining oxygen when steam vent can momentarily be got rid of the bubble that forms in the transfusion or infuse end on it, guarantee that gas can not enter vein, can not form aeroembolism.
