Abstract
A lancing device has improved charging features. In one example embodiment, the charging mechanism generally includes a user actuated portion or charging member and a cam feature for engagement therewith. The charging member includes a finger projection or boss and the cam feature includes a ramped surface. Actuating the charging member causes the finger projection to movably engage the ramp surface of the cam feature and charge the drive mechanism.
Claims22
A lancing device comprising
- a housing;
- a lancet carrier axially movable within the housing between first and second positions, the lancet carrier having an elongate body with a protrusion protruding outwardly from the elongate body and comprising a cam-follower surface;
- a release button extending outwardly from an exterior surface of the housing, the release button comprising a button portion and an annular body at least partially surrounding a portion of the lancet carrier, the annular body having an opening;
- and
- a spring-biased charging actuator pivotally mounted to the housing for moving the lancet carrier into the second position, wherein the charging actuator comprises a rocker lever having a cam-actuator projection configured to engage with the cam-follower surface and a torsion spring, and wherein the charging actuator is pivotal about a first axis transverse to an axis of movement of the lancet carrier along a lancing stroke such that the rocker lever is biased outward from the housing when the lancet carrier is in the first position and pivots into the housing to engage with the cam-follower surface to move the lancet carrier into the second position, wherein the rocker lever is positioned laterally to the release button;
- wherein the protrusion is disposed on an opposite side of the annular body from the button portion of the release button, wherein the protrusion of the lancet carrier is configured to engage with the opening of the annular body to retain the lancet carrier in a charged state when the lancet carrier is retracted into the second position, and configured to release the lancet carrier to propel a lancet to lance a patient's skin when the release button is actuated.

A lancing device comprising
- a housing;
- a lancet carrier axially movable within the housing and comprising a protrusion protruding from the lancet carrier;
- a spring-biased pivoting charging mechanism for moving the lancet carrier between a neutral position and a charged position, the pivoting charging mechanism comprising a rocker lever and a torsion spring, and wherein the pivoting charging mechanism is pivotal about a first axis transverse to an axis of movement of the lancet carrier along a lancing stroke such that the rocker lever is biased outward from the housing in the neutral position and pivots into the housing to engage with a cam-follower surface of the lancet carrier in the charged position;
- a lock-and-release mechanism, the lock-and-release mechanism comprising a release button comprising a button portion, an annular body, and an opening along the annular body;
- wherein a portion of the release button extends outwardly from an exterior surface of the housing and wherein the rocker lever is positioned laterally to the release button,
- wherein the protrusion is disposed on an opposite side of the annular body from the button portion of the release button, and wherein the protrusion of the lancet carrier is configured to engage with the opening of the annular body to retain the lancet carrier in a charged state when the lancet carrier is retracted into the charged position, and configured to release the lancet carrier to propel a lancet to lance a patient's skin when the release button is actuated.
