Abstract: An apparatus (10) for controlling flow of fluid from a wound site of a patient including a cavity (28) connectable to a wound site and a reservoir (16). The cavity (28) may have a first deformed state, and a second state in which it is not deformed or less deformed than in the first state. The cavity (28) may be adapted to manage fluid flow between the wound site and the reservoir (16) during transition of the cavity (28) between the first state and the second state. An actuator element (64) of the apparatus (10) may be adapted to operate on the chamber (28) to transition the cavity (28) from the second state to the first state.

Abstract: Certain embodiments of the present application relate to an adjustable ostomy wafer system including an ostomy wafer and an insert ring 100. The ostomy wafer includes an adjustable layer with an effluent opening through which effluent flows, and the adjustable layer has a body-facing side and a non-body-facing side. The insert ring 100 is capable of providing or increasing convexity of the adjustable layer when the insert ring 100 is pressed against the non-body-facing side of the adjustable layer.

Abstract: A rectal drainage appliance is disclosed comprising a tubular element having an inflatable balloon at a distal end for anchoring the appliance in the rectum. The appliance includes one or more of: (i) first and second auxiliary lumens communicating with the inflatable balloon to provide independent inflation and pressure monitoring paths coupled to the balloon; (ii) a pressure state indicator defined by a mechanical element configured to flip between first and second states or shapes responsive to sensed pressure; and (iii) a collapsible auxiliary lumen larger than the inflation lumen, and configured to permit admission of irrigation fluid. The pressure state indicator may also be used in intestinal drains.
