Abstract
Abstract A method for collecting postpartum fluid loss utilizing a receptacle in the form of a sheet which is positioned beneath the patient. The receptacle includes a first pocket formed by folding an edge of a non-absorbent sheet upon itself and sealing it together, and a second pocket attached to said sheet above said first pocket. The pockets collect amniotic fluid and blood, respectively, and include graduations to permit measurement of the amount of the fluid.
