Abstract
An apparatus for sampling blood which includes a deformable housing defining a chamber that retains liquid. The housing has a pierceable membrane. The apparatus also includes a resilient piercer member that is adjacent the wall of a chamber and adapted to puncture the pierceable membrane. A removable layer that covers at least a portion of the pierceable membrane. Depression of the deformable housing proximate the piercer member urges the piercer member to puncture the pierceable membrane. The piercer member thereby forms an opening, allowing liquid to be drawn through the opening and into the chamber. Thereafter, the piercer member returns into the deformable housing.
