Analyte test device

摘要

An analyte test device is constructed as an integrated, single-use, disposable cartridge which can be releasably installed into a compatible analyte test monitor. In use, the device can be used in conjunction with the monitor to lance the skin of a patient to create a blood sample and, in turn, calculate the concentration of a particular analyte in the expressed blood sample. In one embodiment, the device includes a base and a cover which are affixed together to create a test cartridge which has a substantially flat and low profile design. A lancet carrier is disposed between the base and the cover and includes a anchor fixedly mounted on the base and a lancet support member which is slidably mounted on the base, the anchor and the lancet support member being connected by a spring. A lancet is removably mounted on the lancet support member is disposed directly beneath an analyte test strip which secured to the underside of the cover. In another embodiment, the device includes a cylindrical housing with an open top end and an open bottom end. A spring biased lancet is slidably mounted within the cylindrical housing. An analyte test strip is fixedly mounted within the cylindrical housing and is disposed at an acute angle relative to the lancet.

主权项

1. An analyte test device which is adapted to be removably coupled to a compatible analyte test meter, said analyte test device comprising:
a flat lancet carrier comprising a flat spring and a lancet support surface, said lancet carrier including a top surface, a bottom surface, a front end and a rear end; a lancet comprising a flat member having a needle projecting therefrom, the lancet extending along said lancet support surface and said flat spring, said lancet secured to a first end of said spring; an analyte test strip coupled to the lancet carrier and lancet, the test strip including a plurality of electrodes and assay chemistry; and a housing comprising a base and a cover, the housing including an interior cavity being sized and shaped to receive said lancet carrier, said lancet, and said test strip, wherein said housing comprises a skin receiving surface at a proximal end of said housing and an opening in communication with said interior cavity formed into said proximal end of said housing, wherein electrical contacts of the analyte test strip are accessible to a compatible analyte test meter at a distal end of said housing, and wherein said skin receiving surface is in the form of a notch which extends inward from said proximal end toward a distal end of said housing, wherein the width of the notch is less than the width of the analyte test strip.
