Abstract
An apparatus for collecting urine from a user includes a urinary catheter comprising an outlet to enable liquid to exit therefrom. A first end of a transport channel is operable coupled to the outlet. A pump module, which may be cannister free, is coupled to a second end of the transport channel and is configured to generate suction in the transport channel to draw the liquid into the pump module. The pump module expels the liquid into an output channel. The pump module is configured to draw air as well as the liquid through the transport channel. In certain embodiments, an air entry module is placed at or near the outlet to enable air to enter the transport channel.
