摘要： A cap for use with a dermal tissue lancing device (that includes a housing and a lancet movable with respect to the housing) includes a proximal end for engaging with the housing, a distal end for engaging with dermal tissue and an opening for a portion of the lancet to pass through. The distal end of the cap includes portions for engaging dermal tissue. These portions are resiliently deformable such that, when the cap contacts and is urged towards dermal tissue, the portions deform resiliently, engaging the dermal tissue and approaching theretogether. A process for the collection of a fluid sample (e.g., blood) from dermal tissue includes providing a dermal tissue lancing device with a housing, a cap and a lancet that is moveable with respect to the housing and the cap. The cap includes a proximal end for engaging with the housing, a distal end for engaging with dermal tissue, and an opening for a portion of the lancet to pass through. The distal end of the cap includes resiliently deformable portions for engaging dermal tissue. Next, the cap is contacted with the dermal tissue (e.g., dermal tissue of a fingertip, limb, or abdomen) such that the portions engage the dermal tissue. Subsequently, the cap is urged towards the dermal tissue such that at least first and second portions deform resiliently and approach theretogether to create a bulge in the dermal tissue. The bulge is then lanced to create a puncture from which a fluid sample is collected.

摘要： An electrochemical-based analytical test strip for the determination of an analyte (such as glucose) in a bodily fluid sample (e.g., a whole blood sample) includes an electrically-insulating substrate, at least one working electrode disposed on the electrically-insulating substrate and a graded enzymatic reagent layer disposed on the at least one working electrode. The graded enzymatic reagent layer includes an upper reaction grade that contains an enzyme. The graded enzymatic layer also has a lower spacer grade devoid of the enzyme, the lower spacer grade disposed between the upper reaction grade and the working electrode such that the upper reaction grade is spaced equidistant from the working electrode by the lower spacer grade by a predetermined distance during use of the electrochemical-based analytical test strip. In addition, the upper reaction grade is configured and constituted such that an enzymatic reaction between the enzyme and a bodily fluid sample applied to the electrochemical-based analytical test strip is localized in the upper reaction grade and the lower spacer grade has predetermined mass transport characteristics for a component of the enzymatic reaction that cause mass transport of the component through the lower spacer grade to the working electrode to be slower than mass transport of the analyte through the bodily fluid sample to the upper reaction grade. A method for determining an analyte (such as glucose) in a bodily fluid sample (for example, a whole blood sample) includes applying a bodily fluid sample to such an electrochemical-based analytical test strip.
