Analyte Test Device
First Claim
1. An apparatus for measuring an analyte level within a sample of body fluid, comprising:
- (a) an integrated analyte test strip including a lancet coupled with a test sensor; and
(b) a housing having an opening defined therein and a sealed recess within which the test strip is initially sealed within the housing to shield the test strip from contamination prior to use, and(c) wherein the opening is disposed such that the lancet will pierce a lancing site of a user that is disposed in contact with said housing and over said opening by unsealing the test strip and exposing the lancet through the opening defined in the housing; and
(d) wherein body fluid is automatically applied to the test sensor for measuring an analyte level while the lancing site of the user remains approximately at the same location as during said piercing in contact with the housing and over said opening.

Abstract
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.

13. A method of providing a sample of body fluid to a test strip for measuring an analyte level within the fluid, comprising:
-
(a) loading within a housing an integrated analyte test strip including a lancet coupled with a test sensor, the housing having an opening defined therein, and wherein the test strip is initially sealed within the housing to shield the test strip from contamination prior to use; (b) piercing a lancing site of a user by unsealing the test strip and exposing the lancet through the opening defined in the housing when the lancing site is disposed in contact with said housing and over said opening; and (c) automatically applying body fluid to the test sensor for measuring an analyte level while the lancing site of the user remains approximately at the same location as during said piercing in contact with the housing and over said opening. - View Dependent Claims (14, 15, 16, 17, 20)
