摘要：
Systems, devices and methods for draining and analyzing bodily fluids are disclosed in which a drainage assembly is configured to prevent negative pressure build-up. The drainage assembly generally includes a catheter which may include a drainage lumen, a reservoir, a venting mechanism in fluid communication with the drainage lumen and a positive pressure lumen, and a controller. The venting mechanism may further include a valve which is configured to maintain a closed position, as well as a vent in fluid communication with the valve, where the venting mechanism is configured to inhibit wetting of the vent from fluid within the drainage lumen
