Systems, devices and methods for sensing physiologic data and draining and analyzing bodily fluids

A system for monitoring one or more body parameters, comprising:

• an elongate catheter defining one or more openings at or near a distal end of the catheter;
• a venting mechanism coupled to a proximal end of the catheter, the venting mechanism configured to pass atmospheric air therethrough when negative pressure is applied to the venting mechanism;
• a first lumen coupled to the venting mechanism and in fluid communication with the one or more openings;
• a reservoir coupled to a proximal end of the first lumen and in fluid communication with the one or more openings;
• a controller which is configured to connect to the reservoir and is programmed to control a pressure within the first lumen;
• and
• a pump fluidly coupled to the reservoir via a controller pump interface,
• wherein the controller is further programmed to monitor a urine output received in the reservoir from a patient,
• wherein the controller is further programmed to apply a negative pressure to the first lumen at predefined intervals of time, and
• wherein the controller is further programmed to actuate the pump for airlock clearance whereby a pressure within the reservoir and first lumen reduces until a meniscus of urine within the first lumen passes a minimum point in the first lumen and the pressure reaches an inflection point after which the controller reduces power to the pump to reduce a suction within the reservoir and first lumen.
