1. A fluid collection assembly, comprising:
a fluid impermeable barrier defining a chamber, at least one opening, and at least one fluid outlet, the fluid impermeable barrier including a proximal end region including the at least one fluid outlet and a distal end region opposite the proximal end region, wherein the distal end region is closed;
at least one porous material disposed in the chamber; and
at least one inflation device including a bladder and at least one valve, the bladder including one or more walls defining at least one interior region, the at least one valve configured to selectively permit at least one inflation fluid to flow into and out of the at least one interior region to switch the bladder between a first state and at least a second state, at least a portion of the at least one inflation device contacting an outer surface of the distal end region of the fluid impermeable barrier;
wherein an amount of the at least one inflation fluid present in the at least one interior region is greater when the bladder is in the second state than when the bladder is in the first state;
wherein the fluid impermeable barrier exhibits a first length when the bladder exhibits the first state and a second length when the bladder exhibits the second state, wherein the first length is less than the second length, the first length and second length measured parallel to a longitudinal axis of the fluid collection assembly.
