ABSTRACT:
A method and device for automatic or semi-automatic collection of saliva has a mouthpiece on a wand. The wand is connected to an interface section via a flexible conduit. Saliva is transported by aspiration into the device. Bulk air is removed and saliva is collected in a collection chamber. For collection of volatile components, air flow, vacuum, conduit diameter and length, and collection times are controlled and limited, to reduce loss of volatile components.
