MULTI-LANCET CARTRIDGE AND LANCING DEVICE
First Claim
1. A lancing device for use with a replaceable cartridge assembly having an array of lancets to lance skin, the lancing device comprising:
- a housing having a first section and a second section that move relative to each other between a closed position and an open position, wherein in the closed position the housing holds the multi-lancet cartridge and in the open position the multi-lancet cartridge can be removed and replaced;
a control mechanism including a slider element that moves between a first position and a second position to at least partially operate the device to lance the skin; and
an interlock mechanism including at least one rib, at least one void, and at least one finger, wherein when the housing is in the closed position and the slider is in a first position or between the first position and a second position then the rib aligns with and engages the finger to block movement of the housing to the open position, and when the slider is in the second position then the void aligns with and allows the finger to pass through it to permit movement of the housing to the open position.

Abstract
A medical lancing device including a clam-shell housing that holds a replaceable multi-lancet cartridge. A control mechanism includes a linear-pull slider that is moved in and out to operate various mechanisms of the device. An interlock mechanism includes at least one rib on the slider that engages at least one finger on the housing to lock the housing closed when the slider is in a retracted or only partially extended position. And the interlock mechanism includes at least one void on the slider that aligns with at least one finger on the housing to permit the housing to be opened when the slider is in a fully extended position.

12. A lancing device for use with a replaceable cartridge assembly having an array of lancets to lance skin, the lancing device comprising:
-
a clam-shell housing having a top section and a bottom section that are hingedly coupled together and that move relative to each other between a closed position and an open position, wherein in the closed position the housing holds the multi-lancet cartridge and in the open position the multi-lancet cartridge can be removed and replaced; an advancing mechanism that is adapted to sequentially advance the lancets in the cartridge to an active position; a drive mechanism that is adapted to drive an active-positioned one of the lancets through a lancing stroke; a charging mechanism that is adapted to charge the drive mechanism; a control mechanism including a linear-pull slider element that moves between a retracted position and a extended position to operate the advancing mechanism, the charging mechanism, or both; and an interlock mechanism including at least one rib extending from the slider, at least one void formed in the slider, and at least one finger extending from the housing, wherein the at least one rib and the at least one void are aligned in the same plane, wherein the at least one void is positioned closer to the housing than the at least one rib, and wherein when the housing is in the closed position and the slider is in a first position or between the first position and a second position then the rib aligns with and engages the finger to block movement of the housing to the open position, and when the slider is in the second position then the void aligns with and allows the finger to pass through it to permit movement of the housing to the open position. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
