Abstract: A device (1) for staunching postpartum haemorrhage of the uterus (U). The device (1) comprises an inflatable internal balloon (2) having an inlet connected by a fitting (3) over a distal end (4) of a tubular conduit (5). The tubular conduit (5) has a proximal end (6) for connection to an inflation source for manually inflating the internal balloon (2). A non-return valve (8) is fitted in the conduit (5) at the proximal end (6). The device (1) has an inflatable external balloon (10) for indicating when the surface of the internal balloon (2) has engaged with the wall of the uterus (U). The external balloon (10) also acts as an indicator to indicate subsequent contraction of the uterus (U).
