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
The document describes a lancing device having a housing with a drive mechanism for driving a lancet carrier through a lancing stroke, and an ejection mechanism for ejecting a used lancet from the lancet carrier. The ejection mechanism includes an actuator mounted with respect to the housing and comprising an elongate portion with a free end extending into the housing, and an ejector finger pivotally connected to the elongate portion about a pivot axis so that the ejector finger and the elongate portion pivot relative to one another to engage the lancet carried within the lancet carrier and eject the lancet.
The actuator and the ejector finger are arranged so that the ejector finger is driven by the elongate portion to engage the lancet and eject the lancet from the lancet carrier. The disclosure also describes an optional intervening link pivotally connected to the free end of the elongate portion and connected to the ejector finger to drive and transfer motion during ejection, and alternative embodiments in which the ejection mechanism is positioned and actuated to provide user-activated operation.
The disclosure further characterizes a method of ejecting a lancet from a lancing device by mounting an ejection mechanism within a portion of the lancing device and pivotally mounting a linkage about a pivot axis such that the linkage and the ejection mechanism pivot relative to one another. The linkage is movably mounted within a lancet carrier so that engaging the ejection mechanism and traversing the linkage within the lancet carrier engages the lancet and removes the lancet from the lancing device.
Claims Coverage
The partial content includes two independent claims: an ejection mechanism for a lancing device and a method of ejecting a lancet. The independent claims specify two inventive features centered on a pivotally driven ejector arrangement and a linked, traversing mechanism for engaging and removing the lancet.
Pivotally driven ejector finger by an elongate actuator portion
An ejection mechanism for a lancing device comprising a housing and a drive mechanism for driving a lancet carrier through a lancing stroke, the ejection mechanism comprising an actuator mounted with respect to the housing and comprising an elongate portion with a free end extending into the housing, and an ejector finger pivotally connected to the elongate portion about a pivot axis such that the ejector finger and the elongate portion pivot relative to one another, wherein the ejector finger is configured to be driven by the elongate portion to engage the lancet carried within the lancet carrier and eject the lancet from the lancet carrier.
Mounting and traversing a pivotally linked ejection mechanism to remove the lancet
A method of ejecting a lancet from a lancing device, the method comprising mounting an ejection mechanism within a portion of the lancing device, pivotally mounting a linkage to a portion of the ejection mechanism about a pivot axis such that the linkage and the ejection mechanism pivot relative to one another, movably mounting the linkage within a lancet carrier, engaging the ejection mechanism, traversing the linkage within the lancet carrier to engage the lancet, and removing the lancet from the lancing device.
Across the independent claims, the core inventive concept is an ejection mechanism in which an actuator-driven pivot between an elongate portion and an ejector finger, and in the method a linkage pivoted relative to the ejection mechanism and traversed within the lancet carrier, engages the lancet in the lancet carrier and removes it from the lancing device.
