Abstract
A body fluid sampling device including a hollow tube with a solid, porous, water-wettable nonfibrous nib mounted in and protruding from one end of the tube for collecting, by absorption, a sample of a body fluid such as sweat, tears, or saliva. The sample may be extracted from the nib for analysis by supplying an extraction fluid to the interior of the tube for gravity or vacuum-assisted flow out through the nib. Alternatively, an elongated analysis element such as a strip of paper or a packed column, e.g. containing an agent that changes appearance to indicate the presence of a substance to be detected, may be disposed in the tube for endwise contact with the nib to receive the sample (or components thereof) by absorption.
