Patent ID: 7378007

Claim:
An apparatus for detection and quantitation of an electrochemically-detectable analyte in a sample of blood or interstitial fluid, comprising: a housing; a plurality of electrochemical sensors on a disk positioned in said housing, each of said electrochemical sensors comprising an absorptive member for the uptake of a sample of blood or interstitial fluid; an equal plurality of cutting members in said housing, each of said cutting members being associated with at least one of said electrochemical sensors; a plunger, said plunger sequentially engaging one of the cutting members and moving said engaged cutting member in a cycle from an initial position to a piercing position the electrochemical sensor being disposed such that the plunger causes the cutting member to pierce the skin of the user adjacent the absorptive member, said absorptive member taking up a sample from the pierced skin of the user when it is pierced by the lancet without movement of the apparatus; a connector disposed within said housing for engaging one of said electrochemical sensors and transmitting a signal from said engaged sensor indicative of an amount of analyte in said sample; and a display operatively-associated with said engaged connector said display adapted to display the amount of the analyte to a user.
