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.

Abstract: A stoma adapter is described that is especially suited to a recessed stoma or a flush stoma. The stoma adapter effectively extends the discharge passage from the stoma, protects peristomal skin, and forms a bridge at the interface between the stoma and an ostomy appliance. The stoma adapter contains a substantially unobstructed discharge passage, at least for effluent flowing in a discharge direction. The stoma adapter includes a seal for sealing against the bowel wall. The stoma adapter has collapsing, expanding, flexible and reinforced designs.

Abstract: The body has a fluid inlet port for receiving pressurized fluid and a fluid outlet port connected to the retention balloon. A first passage connects the fluid inlet port and the fluid outlet port, A second passage in the body is connected to the balloon fluid return path and is at the pressure of the retention balloon. A valve prevents fluid flow through the first passage when actuated. The valve includes a pressure-responsive member movable to a position to obstruct fluid flow in response to fluid pressure in the second passage exceeding the predetermined level. Flexible means such as a membrane defines a normally open portion of the first fluid passage, which is closed by the moveable means bearing on the membrane when pressure exceeding the predetermined level actuates the valve.
