摘要:
An analyte detection system is provided with calibration information uniquely specific to the set of test strips to which the sample is to be applied. The calibration information may be stored in permanent memory of the testing device, such that the device is discarded after use of all the test strips in a kit, or it may be stored in a calibration chip accompanying the set of test strips and distributed therewith, thereby enabling re-use of the testing device with a different set of test strips and associated calibration chip.

Body fluid is sampled by causing a syringe (26) mounted in a housing (12) to be displaced towards a skin surface. The syringe (26) remains in the resulting incision while the surrounding body tissue is stimulated by a stimulator ring (70) to urge body fluid towards the incision. Simultaneously, the syringe (26) is moved relative to the incision to keep the incision open.
摘要:
A sampling device (10) for sampling body fluid includes a lancet (12) for making an incision, a capillary tube (18) for drawing up body fluid from the incision, and a test strip (30) affixed to an upper end of the capillary tube (18) for receiving the fluid. An absorbent pad (60) can be disposed between the test strip (30) and capillary tube (18) for spreading out the fluid being transferred to the test strip (30). An on site analyzer such as an optical analyzer (44) and/or an electrochemical analyzer (50) can be mounted in the device for analyzing the fluid. Alternatively, a test strip (30) can be slid through a slot formed in the bottom end of the device so that by passing the device against the skin after an incision has been formed. The test strip (30) will directly contact body fluid emanating from the incision.

摘要:
A disposable lancing element (12) is adapted for use in a lancing device (10) for making an incision through a user's skin. The lancing element (12) includes a body (16) which defines a longitudinal axis, and has a skin lancing member projecting from a front end thereof. A capillary tube (18) is mounted in the body in laterally spaced relationship to the skin lancing member, and is slidable longitudinally relative to the body (16) so as to be extended forwardly past the skin lancing member. The body (16) includes a plurality of circumferentially spaced, radially outwardly projecting bosses (31) formed thereon for guiding the disposable element installation in a carrier element. The kin lancing member may comprise a plurality of needles (14) or barbs arranged in parallel side by side relationship. In lieu of a skin lancing member, the disposable element (12) may possess a longitudinal through hole for conducting a skin piercing laser light beam or pressurized fluid. A capillary tube (18) may have an outwardly flared lower (inlet) end. A capillary tube (18) may possess a sensor for sensing a level of fluid rising therein.
