Abstract: Systems and methods for the expression of bodily fluid from an incision in the skin include devices which bear against the skin in a manner to retain the fluid adjacent the incision site and urge the fluid inwardly toward the incision. Systems utilize a constricting member, a bi-stable expression member, or a pressing member. The present invention further encompasses combinations of the foregoing expression systems with each other, as well as with other expression devices known in the art. Moreover, the invention includes the combination of the expression systems with incising, sampling and/or testing systems, particularly in a single, integrated device. The present invention also contemplates the associated methods for expressing bodily fluid from an incision, including in combination with methods for incising, sampling and/or testing of the bodily fluid.
