Multi-lancet device with sterility cap repositioning mechanism
First Claim
1. A lancing device for use with at least one lancet having a lancet tip covered by a sterility cap, the lancing device comprising:
- a housing defining an opening through which the lancet tip can extend to lance skin, and configured for receiving the lancet with at least a portion of the sterility cap between the lancet tip and the opening; and
a sterility cap repositioning mechanism including a cap-engaging member that is coupled to the housing and operable to move from a first position adjacent the sterility cap on the lancet tip, through a first motion to engage and remove the sterility cap from the lancet tip, and to a second position wherein the sterility cap is repositioned from between the lancet tip and the opening.

Abstract
A lancing device has a carousel of lancets removably received in a housing. In exemplary embodiments, the lancing device includes a sterility cap positioning mechanism that removes sterility caps from the lancets for actuation and afterwards replaces the sterility caps onto the lancets. Preferably, the lancing device includes a lancet advancing mechanism that automatically advances sequential lancets of the lancet carousel for charging and actuating, and a drive mechanism for actuating the lancets. Also provided are replacement lancet carousels, which include a cylindrical carrier with axial openings and a plurality of the lancets axially oriented in the openings.
