LANCING DEVICES HAVING LANCET EJECTION ASSEMBLY
First Claim
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 eject the lancet from the lancet carrier; and
a locking member contacted by the ejection slide to move the locking member in a first direction into blocking engagement with the lancet carrier to prevent forward movement of the lancet carrier when the ejection slide ejects the lancet;
wherein the locking member contacts the housing on one or more bearing surfaces-apart from the ejection slide, the locking member being configured so that substantially all of the force exerted on it by the lancet carrier is transmitted to the housing via the one or more bearing surfaces.

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.

12. 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; 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; 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 (13, 14, 15, 16, 17, 18, 19, 20)
