Systems, devices and methods for draining and analyzing bodily fluids

A device for draining bodily fluids, comprising:

• an elongate body defining one or more lumens configured to receive a bodily fluid from a cavity of a patient body;
• a reservoir in fluid communication with the one or more lumens for receiving the bodily fluid, wherein the reservoir is configured to automatically self-empty when the bodily fluid reaches a predetermined volume within the reservoir;
• an overflow channel fluidly coupled to the reservoir and configured to receive an overflow of the bodily fluid from within the reservoir upon the reservoir failing to self-empty such that the overflow channel inhibits bodily fluid from backing up within the reservoir;
• a pumping mechanism to urge bodily fluid through the one or more lumens and positioned distal to the reservoir, wherein the pumping mechanism is configured such that bodily fluid through the one or more lumens remains unobstructed to maintain an open space within the one or more lumens;
• a controller in communication with at least the pumping mechanism, wherein the controller is configured to determine a total urine output volume of the bodily fluid;
• and
• a vent or valve mechanism in communication with the elongate body and configured to allow air to enter the one or more lumens such that outflow of the bodily fluid through the one or more lumens remains unobstructed and a negative pressure buildup in the cavity is inhibited.
