DRIP INFUSION TUBE WITH HYDROPHOBIC FILTER WHICH CAN OPEN AND CLOSE VENT HOLE OF THE HYDROPHOBIC FILTER

摘要

PROBLEM TO BE SOLVED: To provide a means for solving a disorder that leads to non-drip infusion before the termination of drip infusion due to excessive leak of inner air in a 1g bag of pansporin for intravenous injection through a hydrophobic filter after a drip infusion set equipped with a conventional hydrophobic filter is fixed to the 1g bag of pansporin for intravenous injection, because an inner air pressure inside the 1g bag of pansporin for intravenous injection is reduced.

SOLUTION: The vent hole in a hydrophobic filter of a drip infusion tube of the drip infusion set with the hydrophobic filter is closed before drip infusion, and a part that can open the vent hole when the drip infusion is required is installed.
