Claims
- 1. A rapid response, single use analyte sensor, adapted to measure an analyte concentration in body fluid of a patient having skin having an outer surface, said sensor comprising:
(a) a lancet; (b) a body fluid trapping structure, adapted to trap body fluid on said skin outer surface; (c) an electrochemical analyte measurement system adapted to measure an analyte concentration in body fluid that is trapped on said surface of said skin, by said body fluid trapping structure.
- 2. The analyte sensor of claim 1, wherein said body fluid trapping structure defines an interior volume of less than 100 nanoliters.
- 3. The analyte sensor of claim 1, wherein said body fluid trapping structure defines an interior volume of about 30 nanoliters.
- 4. The analyte sensor of claim 1, wherein said body fluid trapping member is more specifically adapted to trap blood.
- 5. A method of measuring the concentration of an analyte in the body fluid of a patient having skin having an outer surface, said method comprising:
(a) providing a rapid response, single use analyte sensor, adapted to measure an analyte concentration, said sensor comprising:
(i) a lancet; (ii) a body fluid trapping structure, adapted to trap body fluid on said skin outer surface; (iii) an electrochemical analyte measurement system adapted to measure an analyte concentration in body fluid that is trapped on said surface of said skin, by said body fluid trapping structure (b) puncturing said skin with said lancet and withdrawing said lancet from said skin, thereby permitting body fluid to flow into said body fluid trapping structure; (c) using said electrochemical analyte measurement system to measure said analyte concentration in said body fluid.
- 6. The method of claim 5, wherein said body fluid trapping structure defines an interior volume of less than 100 nanoliters.
- 7. The method of claim 5, wherein said body fluid trapping structure defines an interior volume of about 30 nanoliters.
- 8. The method of claim 5, wherein said body fluid trapping structure is blood.
