Integrated blood sampling analysis system with multi-use sampling module
First Claim
1. An apparatus for collecting blood from a patient'"'"'s skin, the apparatus comprising a unit housing including a plurality of sampling segments, each sampling segment comprising a sampling port, a lancet having a tip, the tip adjacent the sampling port, the lancet maintained within the housing and operable to extend the lancet tip through the sampling port to pierce the patient'"'"'s skin positioned adjacent the sampling port, and a sample test chamber in fluid communication with the sampling port, the sample test chamber associated with testing means.

Abstract
A simple, miniaturized, disposable acquisition and test module for monitoring glucose or other analytes successively for multiple times is described. The apparatus is designed to collect and test small volumes of blood in a single step. Many samples can be acquired and analyzed using a single disposable sampling module, minimizing the number of disposables and improving ease of use of the system.

9. A method of collecting and testing a series of blood samples, the method comprising
a) obtaining a sampling module and a reader device, the sampling module including a plurality of sampling segments, each sampling segment adapted to perform a single blood sampling cycle of lancing, collection of a blood sample, and testing of the blood sample, b) coupling the sampling module to the reader device, c) initiating the blood sampling cycle, d) advancing the sampling module to bring another sampling segment online, e) repeating steps c) and d) until substantially all sampling segments on the sampling module have been used, and f) uncoupling the sampling module and reader device.
