Patent ID: 8323212

Claim:
An attachment for mounting to a tip of a body fluid sampling device that includes a pusher for imparting a lancing force, the attachment comprising: a first main body holding a lancing member including a lancing needle; a second main body provided separately from the first main body and holding an analyzing implement for obtaining information on a target component in body fluid, the second main body holding the analyzing implement without holding the lancing member; and a cap removably mounted to the second main body for holding the analyzing implement between the second main body and the cap; wherein the second main body is mounted to the first main body, the second main body being movable together with the analyzing implement relative to the first main body longitudinally of the lancing needle even while the second main body is kept mounted to the first main body and held in contact with a sampling target, wherein the analyzing implement is held by the second main body at a position radially offset relative to the lancing needle for avoiding contact with the lancing needle upon lancing, wherein removal of the cap leaves the analyzing implement held by the second main body, wherein the second main body includes a first seat for holding the analyzing implement, wherein the cap includes a second seat for holding the analyzing implement, the analyzing implement being sandwiched between the first seat and the second seat, and wherein the first seat has a greater holding force for holding the analyzing implement than the second seat.
