Abstract
A depth-control mechanism for selectively-adjusting a lancing stroke depth of a lancet carrier. The depth-control mechanism includes a positioning tab that is configured to be repositioned along an axis that is orthogonal to the lancing stroke axis of the lancet carrier. The depth-adjustment mechanism also includes a tether that is pivotally coupled between the positioning tab and the lancet carrier. The positioning tab is configured to manipulate a pivot axis of the tether to adjust the lancing stroke length of the lancet carrier.
Core Innovation
The described invention is a depth-control mechanism for selectively-adjusting a lancing stroke depth of a lancet carrier. The mechanism includes a fixed engagement post and a positioning tab repositioned by a user relative to the engagement post along an axis orthogonal to the lancing stroke axis of the lancet carrier. A first position corresponds to a first lancing stroke depth and a second position corresponds to a second lancing stroke depth.
The depth-control mechanism further includes a tether pivotally coupled between the positioning tab and the lancet carrier, where the tether has a pivot axis relative to the orthogonal axis. The tether is configured to engage the engagement post at a position on the tether. The pivot axis is adjustable, and the positioning tab manipulates the adjustable pivot axis of the tether to change the position where the engagement post engages the tether and adjust the lancing stroke length of the lancet carrier.
An embodiment for a lancing device also includes a housing having an upper housing shell and a lower housing shell, a drive-mechanism and a lancet carrier translationally secured along a lancing stroke axis. The housing includes an engagement post extending from the lower housing shell and a proximal elongated aperture. A repositioning post is slidably secured along the proximal elongated aperture and is distance-adjustable relative to the engagement post along the axis orthogonal to the lancing stroke axis, and a link couples the repositioning post and the lancet carrier with an elongate slot to slidably receive the repositioning post.
Claims Coverage
The provided independent claims are clm-00001 and clm-00010. Across these claims, the depth adjustment is implemented by two inventive features.
Orthogonal repositioning tab manipulating adjustable tether pivot axis
A positioning tab configured to be repositioned by a user relative to a fixed engagement post along an axis orthogonal to the lancing stroke axis, where a first position corresponds to a first lancing stroke depth and a second position corresponds to a second lancing stroke depth, and a tether pivotally coupled between the positioning tab and the lancet carrier with an adjustable pivot axis that is manipulated by the positioning tab to change where the engagement post engages the tether and adjust the lancing stroke length of the lancet carrier.
Distance-adjustable repositioning post and elongate-slot link directly engaging an engagement post
A repositioning post slidably secured along a housing proximal elongated aperture and distance-adjustable relative to an engagement post along an axis orthogonal to a lancing stroke axis, where the entire repositioning post is able to move along the orthogonal axis, and a link coupling the repositioning post and the lancet carrier, the link comprising an elongate slot to slidably receive the repositioning post, wherein the distance between the engagement post and the repositioning post is adjustable to control the penetration depth of the lancet carrier lancing stroke, and wherein the link is configured to directly engage the engagement post.
Together, the independent claims cover two complementary depth-control architectures: one using a user-repositioned tab that manipulates an adjustable tether pivot engagement with a fixed engagement post, and another using a distance-adjustable repositioning post within an elongate-slot link that directly engages a housing engagement post to control penetration depth.
