1. A lancing device for use with a removable lancet, comprising:
- a housing;
a lancet carrier slidably disposed within the housing and adapted to receive the lancet;
an ejection slide mounted to the housing and configured to move a first direction from an at rest position when ejecting the lancet from the lancet carrier and to move a second direction to the at rest position after ejecting the lancet; and
a locking member comprising a first arm and a second arm, the locking member contacted by the ejection slide to move the locking member into blocking engagement with the lancet carrier to prevent forward movement of the lancet carrier when the ejection slide ejects the lancet, the ejection slide comprising a front-facing surface and a rear-facing surface defining therebetween a recess to receive a portion of the of the second arm when the ejection slide is at the at rest position, the rear-facing surface configured to engage the second arm to move the locking member out of blocking engagement with the lancet carrier when the ejection slide moves in the second direction to the at rest position.

Abstract
A lancing device is provided for use with a removable lancet. The lancing device includes a housing and a lancet carrier slidably disposed within the housing and adapted to receive the lancet. A user-actuated ejection slide is mounted to the housing to eject the lancet from the lancet carrier. A locking member is pivotally mounted to the housing. As the ejection slide moves forward, it rotates the locking member to block forward movement of the lancet carrier during ejection. The locking member is configured so that substantially all of the force exerted on it by the lancet carrier is transmitted to the housing via the pivotal mounting.

11. A lancing device for use with a removable lancet, comprising:
-
a housing; a lancet carrier slidably disposed within the housing and adapted to receive the lancet; an ejection slide mounted to the housing and configured to eject the lancet from the lancet carrier, the ejection slide comprising a front-facing surface and a rear-facing surface; and a locking member configured to move in a first direction into blocking engagement with the lancet carrier due to contact with the ejection slide when the ejection slide begins to eject the lancet, the locking member comprising a first arm and a second arm, the rear-facing surface configured to directly engage the second arm to rotate the first arm out of blocking engagement with the lancet carrier when the ejection slide moves in a second direction to an at rest position; wherein the locking member and lancet carrier are configured so that forward thrust of the lancet carrier continues to urge the locking member in the first direction to remain in blocking engagement with the lancet carrier while the ejection slide ejects the lancet. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)
