Lancing device with side activated charge and eject mechanisms
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.
1. 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 are configured to pivot relative to one another about the pivot axis, 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.
2. The ejection mechanism of claim 1 , wherein the actuator is pivotally mounted to the housing.
3. The ejection mechanism of claim 1 , wherein the ejector finger is pivotally mounted with respect to the elongate portion free end.
4. The ejection mechanism of claim 1 , further comprising a link pivotally connected to the elongate portion free end and connected to the ejector finger.
5. The ejection mechanism of claim 1 , wherein the actuator is translationally mounted to the housing.
6. The ejection mechanism of claim 1 , wherein the ejector finger is mounted with respect to the elongate portion free end.
7. The ejection mechanism of claim 1 , further comprising a link connected to the elongate portion free end and connected to the ejector finger.
8. 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 about the pivot axis,
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.
9. The method of ejecting a lancet from a lancing device of claim 8 , wherein the method further comprises pivotally mounting the ejection mechanism within the lancing device and the ejection mechanism is engaged by pressing the ejection mechanism into the lancing device.
10. The method of ejecting a lancet from a lancing device of claim 8 , wherein the method further comprises translationally mounting the ejection mechanism along the surface of the lancing device and engaging the ejection mechanism by moving the ejection mechanism along the surface of the lancing device.
