Abstract

A waste management system includes a waste transport device and a waste collection device. The waste transport device includes a collection member with a distal end opening having a first cross-sectional area and a proximal end opening having a second cross-sectional area less than the first cross-sectional area, a retention cuff disposed about an outer surface of the collection member, a first section having a lumen in fluid communication with a lumen of the collection member, and a second section having a distal end connected to a proximal end of the first section, the second section including a flush lumen disposed along a length thereof.

Claims

1. A method of managing the fecal material of a patient, comprising:

inserting a distal section of a waste transport system in a collapsed configuration into a patient'"'"'s rectum, the distal section in an expanded configuration defining a distal end opening having a first cross-sectional area tapering to a proximal end opening having a second cross-sectional area less than the first cross-sectional area such that the distal section forms a frusto-conical shape, the distal section including an inflatable retention cuff;

inflating the retention cuff to a first inflated configuration; and

flushing a central lumen of the waste transport system by infusing flushing fluid through a flush lumen disposed along a longitudinal axis of the waste transport system, the flushing fluid passing from the flush lumen directly into the central lumen through a plurality of apertures spaced along a length of the flush lumen.
