Abstract
There is disclosed apparatus for transporting a sample of body fluid such as blood from a first location to a remote test site location. The apparatus operates in conjunction with a fluid manifold module which has a first sample input port, a second washing fluid input port and a third input port for receiving air. There are tubing means coupled to said first, second and third input ports which are coupled together and coupled to a sample output line which extends from the first location to the remote location. The manifold means contains check valves with one valve for blood and one valve for washing fluid and a diaphragm pump for air. There are logic means which selectively operate the valves and pump to allow the sample line to receive a sample separated by air barriers from washing fluid solution. In this manner, a predetermined volume of sample is transported from the first location to the remote test site location. At the test site location, the presence of sample is detected by detection means and the sample is directed to a test site. The remainder of materials such as the washing fluid and air are discharged at the remote location. The system includes flexible tubing and t…
