DIALYZING LIQUID-COLLECTING CONTAINER.

摘要

A liquid container has a dialyzing membrane forming first and second compartments within a chamber on either side of the membrane. An inlet passage feeds into only the first compartment, which is pumpable to aspirate liquid into it via the inlet passage. A liquid-pervious member in the first compartment backs up the membrane to support it when there is a greater pressure in the second compartment than in the first.
