Abstract
A single-use lancet cartridge for inserting into a multi-use lancet driver assembly of a meter housing includes an elongated lancet housing with an open end, a lancet within the lancet housing and movable between a retracted and resting orientation to a piercing orientation through the open end, and a re-use prevention component that is a rotated drive wing incorporated within the lancet cartridge and oriented to cooperatively engage with a driver piston of the multi-use lancet driver assembly only one time thereby preventing the lancet from being moved into a piercing orientation a second time.
Core Innovation
A single-use lancet cartridge for inserting into a multi-use lancet driver assembly is described. The cartridge includes an elongated lancet housing with an open end, and a lancet movable between a retracted and resting orientation and a piercing orientation through the open end. The cartridge incorporates a re-use prevention component oriented to cooperatively engage with a driver piston external to the lancet cartridge only one time thereby preventing the lancet from being moved into a piercing orientation a second time.
The re-use prevention component is a rotatable drive wing having at least a first drive wing portion directly connected to a lancet body. The first drive wing portion is rotatable between a first position and a second position, where the first position presents the first drive wing portion extending laterally from a side of the lancet for cooperative engagement with the driver piston. In the second position, the first drive wing portion fails to extend beyond the side of the lancet and is incapable of cooperative engagement with the driver piston.
A lancet system with safety feature includes a multi-use lancet driver assembly having a driver piston contained within a meter housing and a single-use lancet cartridge. The system includes a rotatable re-use prevention drive wing architecture and meter components that manage cartridge insertion/ejection and related safety engagement.
Claims Coverage
The independent claims are clm-00001 and clm-00005, covering a single-use lancet cartridge with a built-in one-time re-use prevention component and a lancet system combining a meter-contained multi-use driver assembly with the single-use cartridge. Across these independent claims, there are two main inventive feature sets: one-time cooperative engagement between the cartridge re-use prevention component and the driver piston, and a rotatable drive wing that enables engagement in a first position and prevents engagement in a second position.
Single-use lancet cartridge with one-time driver piston cooperative engagement
A single-use lancet cartridge for inserting into a multi-use lancet driver assembly, including an elongated lancet housing with an open end, a lancet movable between a retracted and resting orientation to a piercing orientation through the open end, and a re-use prevention component incorporated within the lancet cartridge and oriented to cooperatively engage with a driver piston of the multi-use lancet driver assembly external to the lancet cartridge only one time thereby preventing the lancet from being moved into a piercing orientation a second time.
Rotatable drive wing re-use prevention component position-dependent engagement
The re-use prevention component is a rotatable drive wing having at least a first drive wing portion directly connected to a lancet body of the lancet and rotatable between a first position and a second position wherein the first position has the first drive wing portion extending laterally from a side of the lancet and wherein the second position has the first drive wing portion failing to extend beyond the side of the lancet, wherein when the first drive wing portion is in the first position the first drive wing portion is presented for cooperative engagement with the driver piston and when in the second position the first drive wing portion is incapable of cooperative engagement with the driver piston.
Lancet system with meter housing multi-use driver assembly and one-time cartridge re-use prevention
A lancet system with safety feature comprising a multi-use lancet driver assembly having a driver piston contained within a meter housing, and a single-use lancet cartridge having a lancet housing with an open end, a lancet movable between a retracted and resting orientation to a piercing orientation through the open end, and a re-use prevention component incorporated within the lancet cartridge and oriented to cooperatively engage with the driver piston of the multi-use lancet driver assembly only one time thereby preventing the lancet from being moved into a piercing orientation a second time.
The independent claims focus on a cartridge-integrated, one-time re-use prevention component that cooperatively engages the meter-contained driver piston only once. The engagement is enabled by a rotatable drive wing in a first position and prevented when the rotatable drive wing moves to a second position where the wing portion fails to extend laterally beyond the lancet side and is incapable of cooperative engagement.
Stated Advantages
Prevents the lancet from being moved into a piercing orientation a second time.
