Abstract

A device for detecting postpartum hemorrhage is provided. A mat defines a proximal end and a distal end. The mat is configured to be disposed between a support and a patient and has a surface with a fluid flow region configured to direct flow of bodily fluids from the patient towards the distal end of the mat. A first detachable and optionally sealable bag is configured to receive the bodily fluids from the patient in a first operational mode of the device. A second sealable bag is configured to receive the bodily fluids from the patient in a second operational mode of the device. The second sealable bag comprises a visual volume indicator to measure the bodily fluids collected in the second sealable bag.
