RECTAL DRAIN APPLIANCE

摘要

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.

1. A rectal drainage appliance comprising:
a tubular element defining a drain passage for effluent from the rectum; a inflatable balloon at a first distal end of the tubular element for insertion into the rectum; an auxiliary lumen communicating with the inflatable balloon; and a pressure indicator coupled to the auxiliary lumen for indicating a pressure level within the balloon, the pressure indicator comprising a first mechanical element configured to flip between first and second physical states depending on the sensed pressure.
