System and method for sampling device for bodily fluids
View Patent ↗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.
1. A diverter valve for taking a sample from a patient, said diverter valve comprising:
a valve body containing a valve comprising a first diverter lumen and a second diverter lumen, said valve having a first position in which a distal end of said valve is in fluid communication with a source of vacuum and a second position in which said distal end of said valve is in fluid communication with a sputum trap via said first diverter lumen and said sputum trap is in fluid communication with said source of vacuum via said second diverter lumen, wherein said valve is moved from said first position to said second position by the connection of said sputum trap to said valve body by twisting said valve body in a keyway in said sputum trap.
2. The diverter valve of claim 1 further comprising a loss prevention media in said sputum trap to prevent said sample from escaping.
3. The diverter valve of claim 2 wherein said loss prevention media is a nonwoven fabric, breathable film, or combination thereof.
