There is provided a device for sampling bodily fluids. Some embodiments have a handle, a lumen, and a diverter valve. The distal end of the handle is adapted to connect with a sampling device and is in fluid communication with the lumen. There is a vacuum connection on the proximal end of the handle that is also in fluid communication with the lumen. A suction valve may desirably be located in the lumen to control the application of vacuum from the vacuum connection to the sampling device. The diverter valve directs the flow through the lumen such that a sample from the patient goes into a sputum trap when the trap is connected. The device may further have a saline port in fluid communication with the lumen, located distal to the suction valve, for rinsing the tube and diluting secretions.
