Method and apparatus for storing an analyte sampling and measurement device
First Claim
1. A fluid sampling device comprising:
- an instrument housing;
a cartridge defining a plurality of cavities, the cartridge sized to fit within the instrument housing; and
a cassette for housing the cartridge, the cassette sized to fit within the housing;
a plurality of penetrating members at least partially contained in the cavities of the cartridge wherein the penetrating members are slidably movable to extend outward from the cartridge to penetrate tissue, the cavities each having a longitudinal opening providing access to an elongate portion of the penetrating member;
a sterility barrier coupled to the cartridge, the sterility barrier covering a plurality of the longitudinal openings, wherein the sterility barrier covering the lateral openings is configured to be moved so that the elongate portion may be accessed by the gripper without touching the barrier; and
desiccant material inside the device to reduce humidity therein.

Abstract
Methods and apparatus are provided for storing used and unused test strips in a desiccated environment. In one embodiment, the method comprises providing an analyte sampling device having a instrument housing and a cartridge having a plurality of penetrating members wherein the penetrating members are slidably movable to extend outward from lateral openings on the cartridge to penetrate tissue, where the sampling device include a plurality of analyte sensing members. The device is designed to use a cassette that will fit inside the device but also contain the cartridge in a desiccated environment. The user may open a lid or access door on the cassette to allow for lancing and sample capture. The lid is closed to re-establish a sealed condition inside the cassette once lancing is complete.

30. A device for use in penetrating tissue to obtain a body fluid sample, comprising:
-
an instrument housing;
a cartridge; and
a plurality of penetrating members slidably coupled to the cartridge, each of the penetrating members having a distal end sufficiently sharp to pierce tissue and each of the penetrating members being moveable relative to the other ones of the penetrating members, so that the distal end of the respective penetrating member is movable to penetrate tissue;
wherein each of the penetrating member is a bare lancet does not penetrate an outer sterility barrier during actuation;
a plurality of analyte sensing members mounted about the instrument housing;
a cassette to contain the cartridge and sized to fit within the instrument housing, the cassette providing a sealed environment when a lid on the cassette is closed to improve the storage condition of the analyte sensing members; and
desiccant in the device. - View Dependent Claims (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43, 44, 45, 46, 47, 48, 49, 50, 51, 52, 53, 54, 55, 56, 57, 58)

59. A method comprising:
-
providing an analyte sampling device having a instrument housing and a cartridge having a plurality of penetrating members wherein the penetrating members are slidably movable to extend outward from lateral openings on the cartridge to penetrate tissue;
providing the cartridge in a sealed cassette containing desiccant, wherein the cassette has a lid that is opened when the cartridge is about to be used.
