Abstract
A saliva sampling device includes a collection container, a saliva collector and a sample container. The sample container is inserted into the collection container and becomes fluidly coupled thereto by inserting the saliva collector into sample container and pressing it therein. This allows a sample of saliva to be collected, separated from the saliva collector and retained within the collection container for testing. The saliva collector includes a piston fitting closely within the sample container and a porous mass which may be compressed by the piston in the sample container to extract the sample of saliva for distribution to the collection container. A buffering solution may be retained within the sample container for mixing with the sample of saliva. The saliva sampling device may include a sample container, a saliva collector and at least one reagent container which may be used with a rotatable cylinder to mix a buffered sample of saliva with at least one reagent solution for conducting a laboratory test on site. The saliva sampling device may also include at least two sample containers and at least two saliva collectors which may be used with a cylinder to mix a buffered sample of saliva with at least one reagent solution for conducting a laboratory test on site. This allows at least two people to be tested with the same saliva sampling device.
