PROBLEM TO BE SOLVED: To restrain foams from being produced even in the case where medical appliances with polluted matters attached thereto are washed together with a collecting bag and to wash down the polluted matters efficiently without declining effect of washing by a method wherein a basic material mainly composed of a water-soluble polymer is made to contain a compound having defoaming property. SOLUTION: The present collecting bag is made of a basic material mainly composed of water-soluble polymer and the basic material is made to contain a compound having defoaming property. For the water-soluble polymer, matters to be formed in a film such as, for instance, water-soluble synthetic polymer, water-soluble semisynthetic polymer, water-soluble natural polymer and the like are cited. Polyvinyl alcohol, for instance, that is soluble in cold water or warm water and soluble in water at the temperature of 60 deg.C or below is desirable. For the compound having defoaming property, matters having defoaming property to be well mixed with a water-soluble polymer such as, for instance, a silicone compound, lower alcoholic compound, mineral oil compound, organic polar compound or the like are cited, and the content shall be 0.1-20 wt.% against the water-soluble polymer. |
