Abstract
A lancing device having a housing with a proximal end, a distal end and a longitudinal axis. The lancing device also has a lancet carrier translationally supported with respect to the housing. The lancet carrier has a proximal end and a distal end. The lancing device additionally has a charging mechanism and/or an ejection mechanism adapted to pivot into the lancing device for engaging portions of the lancet carrier to perform the same.
Core Innovation
A lancing device includes a housing having a longitudinal axis extending between a proximal end and a distal end, and a lancet carrier translationally mounted for axial movement within the housing. The device includes a drive mechanism secured to the lancet carrier to drive the lancet carrier through a lancing stroke, and a charging mechanism having an actuator pivotally mounted to the housing and an elongated arm within the housing comprising a free end and a pivot end pivotally mounted to the housing.
The charging mechanism is engaged with respect to the drive mechanism to charge the drive mechanism during pivotal movement. Upon actuation, the actuator engages the elongated arm, and the elongated arm pivots about the pivot end in response to actuation to retract the lancet carrier and charge the drive mechanism. The device also includes a linkage pivotally connected to and driven by the elongated arm toward the housing distal end, where the linkage engages a lancet carried within the lancet carrier and ejects the lancet from the lancet carrier.
In an additional configuration, the lancing device includes an ejection mechanism comprising an actuator pivotally mounted to the housing, an elongate arm mounted to the actuator and extending within the housing, and a linkage pivotally connected to and driven by the elongate arm toward the housing distal end. The linkage engages the lancet carried within the lancet carrier and ejects the lancet from the lancet carrier.
Claims Coverage
The document contains four independent claims. The inventive features focus on a charging mechanism and its engagement with a drive mechanism during pivotal movement, and on ejection mechanisms that use a linkage driven toward the housing distal end to engage and eject a lancet from a translationally mounted lancet carrier.
Lancing device with pivotally actuated charging mechanism that retracts the lancet carrier and charges the drive during pivotal movement
A lancing device with a housing with a longitudinal axis, a lancet carrier translationally mounted for axial movement, and a drive mechanism secured to the lancet carrier to drive the lancet carrier through a lancing stroke. The device includes a charging mechanism comprising an actuator pivotally mounted to the housing and an elongated arm within the housing pivotally mounted to the housing, where the charging mechanism can be engaged with respect to the drive mechanism to charge the drive mechanism during pivotal movement. The actuator engages the elongated arm upon actuation, and the elongated arm pivots about the pivot end to retract the lancet carrier and charge the drive mechanism.
Lancing device with pivotally actuated ejection mechanism driven by elongate arm toward the housing distal end
A lancing device for carrying a lancet through a lancing stroke including a housing with a longitudinal axis, a lancet carrier translationally mounted for axial movement, and an ejection mechanism comprising an actuator pivotally mounted to the housing. The device further includes an elongate arm mounted to the actuator and extending within the housing, and a linkage pivotally connected to and driven by the elongate arm toward the housing distal end, where the linkage is configured to engage the lancet carried within the lancet carrier and eject the lancet from the lancet carrier.
Lancing device with charging actuator pivotally mounted to the housing and ejection mechanism driven by elongate arm to engage the lancet
A lancing device for carrying a lancet through a lancing stroke including a housing with a longitudinal axis, a lancet carrier translationally mounted for axial movement, and a drive mechanism configured to drive the lancet carrier through the lancing stroke. The device includes a charging mechanism comprising a charging actuator pivotally mounted to the housing, where the charging mechanism is engaged with respect to the drive mechanism to charge the drive mechanism during pivotal movement. The device further includes an ejection mechanism comprising an ejection actuator mounted to the housing, an elongate arm mounted to the ejection actuator and extending within the housing, and a linkage pivotally connected to and driven by the elongate arm toward the housing distal end, where the linkage is configured to engage the lancet carried within the lancet carrier.
Lancing device with translationally mounted ejection actuator and pivotally connected linkage that ejects the lancet
A lancing device including a housing with a longitudinal axis, a lancet carrier translationally mounted for axial movement within the housing, and an ejection mechanism comprising an actuator translationally mounted to the housing. A linkage is pivotally connected to and driven by the actuator, where the linkage is configured to engage the lancet carried within the lancet carrier and eject the lancet from the lancet carrier.
Across the independent claims, the coverage centers on a charging mechanism with an actuator and an elongated arm that retract the lancet carrier and charge a drive mechanism during pivotal movement, and on ejection mechanisms that use a linkage driven toward a housing distal end to engage and eject a lancet from a translationally mounted lancet carrier. The independent claims further vary the ejection actuation between pivotally mounted actuators and a translationally mounted actuator, while maintaining a linkage that performs lancet engagement and ejection.
