Abstract: A film positioner includes at least one film guide having a plurality of parallel guide bars. The guide bars are operably receptive to at least one film material strip and extend at least partially across the film positioner with axes nonparallel to a lateral extent of the film positioner. A method of changing a lateral position of at least one film material strip includes wrapping the at least one film material strip is around a first guide bar of the plurality of guide bars, thereby turning the at least one material strip to a guide angle from the flow direction. The at least one material strip is wrapped around a second guide bar of the plurality of guide bars, thereby turning the at least one material strip from the turn angle back to the flow direction at a second lateral position different from the first lateral position.

Abstract: A lancet type device (20) having a movable and retractable lancet (46) is disclosed. A lancet (46) beyond the end of a lancet body (24). The device includes an actuating, a retracting and locking mechanisms that move and retract a sharp distal tip (48) linearly into and out of contact with a patient's skin. The actuating mechanism includes an arm (26) with a blind conical hole (56) and a conical top (52) of a lancet body (24). The retracting and locking mechanism includes a blind cylindrical hole (58) of an arm (26), a cylindrical head (50) of a lancet body (24) and a spring (54). In one embodiment, a spring (54) is molded as a part of a lancet body (24). In another embodiment, a spring (68) is made as separate part from metal. Contact between a blind conical hole (56) and a conical top (52) moves a lancet body (24) in a linear direction along the axis. Contact between a cylindrical head (50) and a blind cylindrical hole (56) locks an arm (26) inside a case (22).
