Since the exhaust half filling injectious filtration liquid storage bottle, a transfusion bottle with exhaust window, including bottle cover, bottle funnel, exhaust membrane, membrane exhaust cover and microporous membrane, and a drop funnel bottle cover sealing bottle shell composition, liquid flow from the drop drop drop funnel cover, shell side wall with an exhaust opening the exhaust hole in the dropper shell membrane covering the exhaust opening in the side wall, the microporous membrane mounting hole in the shell side of the bottle wall exhaust downstream; when used can not drop operation can be achieved automatically to the exhaust liquid into the dropper window position in the central part of the tension in the empty hydrophilic liquid drop in microporous membrane below relying on the microporous membrane makes the liquid remains, prevent liquid emptying and further reduce the pressure, liquid pressure, avoid blood backflow into the infusion tube caused by blood When the infusion is repeated, the liquid can be filled again, and the first liquid level is raised, and the filtering action of the liquid medicine is realized simultaneously. The device is more convenient for operators and safer for patients.
