Urine management systems

A urine suction system comprising:

• a cannister comprising a first port;
• a first tube coupled to the first port and configured to receive fluid from the first port;
• and
• a pump system comprising:
• a pump inlet coupled to the first tube and configured to receive the fluid from the first tube,
• a first sensor configured to provide a signal associated with a pressure of the fluid within the first tube,
• a pump configured to receive the fluid from the pump inlet,
• a pump outlet configured to receive the fluid from the pump, and
• a processing circuit comprising a memory and one or more processors, the one or more processors configured to:
• receive the signal from the first sensor,
• determine the pressure based on the signal,
• compare the pressure to a pump threshold,
• instruct the pump to provide the fluid at a first rate when the pressure is less than the pump threshold, and
• instruct the pump to provide the fluid at a second rate greater than the first rate when the pressure is greater than or equal to the pump threshold.
