PUSH-TO-CHARGE MECHANISM FOR LANCING DEVICE

A lancing device has a charging mechanism that operates to convert an external push action by a user to an internal pull action that retracts and charges a lancet for use in a lancing stroke. In some embodiments, the charging mechanism includes a user-actuated charging push-button, a reverse charging member coupled to a lancet carrier, and a reverse-motion conversion member coupled therebetween. Depressing the user-actuated member in a first longitudinal direction causes transverse movement of the conversion member, which in turn causes longitudinal retraction of the reverse charging member and the lancet carrier coupled thereto in a second longitudinal direction opposite the first direction, thereby charging a drive mechanism of the lancing device. In other embodiments, a rack-and-pinion gear mechanism provides the same push-to-pull functionality.
