20150359474 | 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. | 12-17-2015 |
20150012026 | LANCET EJECTION AND ADVANCEMENT MECHANISM FOR MULTI-LANCET CARTRIDGE - A lancing device includes an advance-and-eject mechanism with a positioning member for manipulating a series of interconnected lancets. The advance-and-eject mechanism includes an actuator, a control channel, a cam-and-follower mechanism, one or more axial-contact members, and one or more angular-contact members. Actuating the actuator relative to the control channel imparts rotational and axial forces on the positioning member, and the cam-and-follower mechanism selectively restricts rotational and/or axial motion of the positioning member to induce first-stage rotation, second-stage translation, third-stage rotation, and fourth-stage translation. The first-stage rotation rotates the axial-contact members into an interference position, the second-stage translation advances the axial-contact members and the lancet, the third-stage rotation rotates the angular-contact members and the lancet to sever its rearside connection, and the fourth-stage translation advances the axial-contact members and the lancet to a position free of the serial-interconnected lancets thereby ejecting it from the lancing device. | 01-08-2015 |

The lancet carrier deflects the leg in a forward phase of the lancing stroke, and then the leg contacts the stop surface to stop the forward motion of the lancet carrier at an extended lancing position. The stop surface can be adjustably positioned so that different portions thereof are engaged to stop the lancet carrier at deeper or shallower positions. In example embodiments, the depth-adjustment mechanism includes a rotary dial and an extension arm of the leg, with the dial including a rotary wheel and a rotary shaft extending axially therefrom, the wheel forming the movable adjustment member, and the shaft forming the adjustably positioned stop surface. | 03-27-2014 |
20140074138 | 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. | 03-13-2014 |

Rotation of the handle rotates the first cam member with it, causing the first cam member to rotate against the second cam member, which in response traverses axially because it is restricted from rotation, thereby retracting the lancet carrier to a retracted or charged state. | 02-27-2014 |
