Narrow-profile lancing device
First Claim
Patent Images
1. A lancing device comprising:
- a lancet carrier translationally mounted within a housing and movable along a path of travel between a retracted position and an extended position;
at least one drive spring engaged between the lancet carrier and the housing;
a charging mechanism for moving the lancet carrier into the retracted position and energizing the at least one drive spring; and
a release mechanism for holding the lancet carrier in the retracted position until actuated to release the lancet carrier to move along the path of travel under the influence of the at least one drive spring toward the extended position;
wherein the lancet carrier, the at least one drive spring, the charging mechanism and the release mechanism are all intersected by a reference plane containing the path of travel.

Abstract
A lancing device having a substantially narrow profile housing, optionally configured for attachment in place of a battery cover of a blood-glucose testing meter. A miniature lancet has an oversized sterility cap with a T-shaped end for ease of handling and loading into a lancing device. A flattened portion of the sterility cap is angularly offset, for example generally perpendicular to, a flattened portion of the lancet body, such that twisting the sterility cap into alignment with the lancet body serves to detach the sterility cap from the lancet body.

28. A lancing device comprising a housing having a slotted lancet opening with a first opening dimension greater than a second opening dimension thereof, and a lancet releasably engagable with said lancing device;
-
said lancet having a lancet body with a sharp lancet tip projecting therefrom and a cap removably covering the sharp lancet tip;
wherein the lancet body has a first lancet body dimension less than the first opening dimension but greater than the second opening dimension, and has a second lancet body dimension less than the second opening dimension;
whereby the lancet body resists rotation within the slotted lancet opening upon twisting of the cap to detach the cap from the lancet body. - View Dependent Claims (29, 30, 31, 32)
