摘要:
A method of obtaining a test sample from a specimen using a lancet system includes engaging a lancet driver against a drive wing of a lancet system, the lancet system having a major portion of a lancet member slidably engaged within a lancet carrier and a sensor strip with a sample chamber attached to the lancet carrier, the lancet system having a lance connected to a first end of a lancet body of the lancet member wherein the lance is movable from a retracted position within the lancet carrier to an extended position outside the lancet carrier, the drive wing extending outwardly and transversely from the lancet body, the major portion of the lancet member having a sinuous portion with a distal end restricted from movement by the lancet carrier, the sinuous portion being non-compressible when initially disposed within the lancet carrier wherein the drive wing prevents the sinuous portion from being compressed, moving the drive wing with the lancet driver a predetermined distance causing the lancet tip to move from the retracted position to the extended position, and disengaging the lancet driver from the drive wing, the lance being automatically moved from the extended position to the retracted position.

A blood glucose measuring system includes a lancet assembly and a meter for use with the lancet assembly. The lancet assembly has a lancet member with a lance, a lancet body having a drive wing extending outwardly from a side, and a sinuous portion, and an elongated carrier having a lancet member recess to contain the lancet member. The elongated carrier has an open end, a closed end, a side elongated opening for receiving the drive wing therethrough, and an anchoring member operatively connected to the end of the sinuous portion. The meter includes a measuring circuit, a lancet trigger, and a lancet driver where the lancet driver includes a driver piston engageable with the lancet trigger and a charging member that operatively engages with the driver piston to move the driver piston into an armed position and to stop the driver piston when released from the armed position.
摘要:
In combination, a blood glucose testing meter comprising a slot for receiving a test strip, a display, one or more control devices, and a battery compartment and a lancing device for releasable coupling to the blood glucose test meter over the battery compartment. The lancing device releasably couples directly to the testing meter over the battery compartment. Optionally, the lancing device is mounted to a mounting clip releasably coupled to the testing meter over the battery compartment. The lancing device comprises a housing, a lancet opening disposed at one end of the housing, an energizing member for charging the lancing device, and a release button for activating a lancet within the lancing device.
摘要:
A lancing device including a drive mechanism with a drive spring and a lancet carrier engaged and driven by the drive spring, and further including a lancet with a sharp lancing tip, wherein the lancet floats relative to the carrier and is decoupled from the drive mechanism during at least a portion of a lancing stroke. In one example embodiment the lancet is held in a sled that floats in the carrier, and in another example embodiment the lancet by itself floats in the carrier.
摘要:
A medical lancing device including a replaceable multi-lancet cartridge. The lancing device includes an advancing mechanism that advances lancets within the cartridge into an active position, separates a protective cap from the active lancet, and energize a drive mechanism of the lancing device. A cap displacement mechanism moves the separated cap out of the travel path of the active lancet. In a first example embodiment, the cap displacement mechanism includes a cantilevered spring arm that displaces the detached cap of the active lancet. In a second example embodiment, the cap displacement mechanism includes a spring-biased cam-driven plunger that displaces the detached cap of the active lancet. Then an activation mechanism releases the energized active lancet to traverse the unobstructed lancing stroke path to pierce the subject's skin at a desired lancing site.

A housing having an actuator mechanism and a replaceable carousel having a series of lancets. The carousel is removably received in the housing and the actuator mechanism is operable to actuate the individual lancets. In exemplary embodiments the lancing device has, amongst other features, key and detent mechanisms for orienting and securing the carousel in the housing, tangentially configured lancets for compactness, actuator alignment features for aligning the actuator with the lancets, charging mechanisms for ease in charging the lancets for launching, and shutter mechanisms for retaining the lancets in the housing after launching. Also included is a method for lancing using a lancing device according to the invention.
