Abstract
Systems, devices and methods for draining and analyzing bodily fluids and assessing health are described generally comprising a pumping mechanism which is fluidly connectable at a first end to a portion of a drainage line and a venting mechanism having a one-way valve and which is connectable at a first end into fluid communication with a drainage catheter and the drainage line. The pumping mechanism may be configured to create a negative pressure within the drainage line when the pumping mechanism is in communication with the drainage line, and the one-way valve may be configured to open to an environment when the venting mechanism is connected at the first end and when the drainage line is at a pressure less than an environmental pressure such that an airlock is prevented from forming within the drainage line.
