Abstract
A lancet carrier for an integrated lancet sensor assembly incorporating a lance cover includes an elongated body with a bottom, an open top, a body open end and a body closed end, a lancet-receiving recess with a recess bottom surface, the recess extending between the open end and the closed end, and a trough-forming member forming a trough with a trough open end in communication with the body open end, the trough-forming member longitudinally extending a predefined distance along the bottom from the body open end, the trough replacing a portion of the recess bottom surface at the body open end.
Claims11
A lancet carrier for an integrated lancet sensor cartridge incorporating a lance cover, the lancet carrier comprising:
- an elongated body with a bottom, an open top, a body open end and a body closed end;
- a lancet-receiving recess with a recess bottom surface, the recess extending between the body open end and the body closed end;
- and
- a trough-forming member forming a trough with a trough wall, a trough open end in communication with the body open end and a trough closed end transverse to the trough wall, the trough closed end directly connected to the bottom of the elongated body, the trough-forming member longitudinally extending continuously a predefined distance along the bottom from the body open end and terminating in a transverse wall at the trough closed end and below the bottom, the trough replacing a portion of the recess bottom surface at the body open end wherein the lancet-receiving recess is stationary relative to the trough-forming member.
A lancet carrier for an integrated lancet sensor cartridge, the lancet carrier comprising:
- an elongated body with a bottom, an open top, a body open end and a body closed end;
- a lancet-receiving recess with a recess bottom surface, the recess extending between the body open end and the body closed end;
- and
- an external bottom rib directly connected to and centered on the bottom of elongated body and extending longitudinally along and parallel to a major portion of an outside bottom surface of the lancet carrier, and a carrier retaining notch formed laterally in the external bottom rib and having a carrier locking surface transverse to the longitudinal axis of the external bottom rib, the carrier locking surface engageable with a cartridge lock of a meter to prevent longitudinal movement of the lancet carrier when a lancet of the integrated lancet sensor cartridge is operated.
A method of reducing damage to a sensor in an integrated lancet sensor cartridge having a lancet carrier with an elongated recess containing a lancet, the method comprising:
- forming a lancet carrier having a trough-forming member with a trough wall, a trough open end and a trough closed end transverse to the trough wall, the trough closed end directly connected to a bottom of the lancet carrier, wherein the trough-forming member longitudinally extends continuously a predefined distance along a bottom of the lancet carrier from a carrier open end and terminating in a transverse wall at the trough closed end and below the bottom wherein a trough formed by the trough-forming member replaces a portion of a bottom surface of the recess adjacent the open end and wherein the elongated recess is stationary relative to the trough-forming member.
