Abstract
Body fluid is sampled by causing a syringe mounted in a housing to be displaced toward a skin surface. The syringe remains in the resulting incision while the surrounding body tissue is stimulated by a stimulator ring to urge body fluid toward the incision. Simultaneously, the syringe is moved relative to the incision to keep the incision open. Such movement of the syringe may comprise reciprocation in the longitudinal or lateral directions, or both. Alternatively, the movement of the syringe may comprise rotation about a longitudinal center line of the syringe, with the pointed end of the syringe being in the shape of one-half of a cone segment. After the body fluid has been pooled, suction is created in a collection tube disposed in communication with the syringe, to draw body fluid inwardly through the syringe.
