Abstract
A technique for efficiently sampling blood from body tissue by reducing pressure on the body tissue. In the present technique a body tissue is placed under reduced pressure to improve perfusion of blood in the body tissue before lancing. An embodiment of this apparatus includes a lancet carried by a piston slidable in a housing, a mechanism for transmitting mechanical energy internally in the apparatus for creating the reduced pressure on the body tissue. The apparatus also includes a driver that drives the lancet for lancing. The apparatus has a head in the housing for contacting the body tissue in an air-tight manner against suction forces. In the head facing the body tissue is a channel in which the air pressure can be reduced.
