1. A system for determining the level of an analyte in a biological fluid sample from a patient, the system comprising:
- an analyte detector configured to determine the level of at least one analyte in the biological fluid sample;
a sample extractor configured to withdraw the biological fluid sample through the skin of the patient; and
a multi-use disposable sample element comprising;
a sample cell configured to receive at least a portion of the biological fluid sample and to hold that portion while the analyte detector analyzes the portion of the biological fluid sample;
a sample supply passage in fluid communication with the sample cell and configured to facilitate entry of the at least a portion into the sample cell; and
a container configured to store discarded biological material.

Abstract
A reagentless whole-blood analyte detection system that is capable of being deployed near a patient has a source capable of emitting a beam of radiation that includes a spectral band. The whole-blood system also has a detector in an optical path of the beam. The whole-blood system also has a housing that is configured to house the source and the detector. The whole-blood system also has a sample element that is situated in the optical path of the beam. The sample element has a sample cell and a sample cell wall that does not eliminate transmittance of the beam of radiation in the spectral band.

15. A method of using a multi-use disposable sample element comprising a sample cell and a container for discarded biological material with an analyte detection system configured to perform multiple analyses on biological fluid samples from a patient, the method comprising:
-
a. extracting a sample of biological fluid from the patient; b. directing at least a portion of the sample of biological fluid through a sample supply passage that is in fluid communication with the sample cell and that is configured to facilitate entry of the at least a portion of the sample into a sample cell; c. directing the at least a portion of the sample into the sample cell; d. holding the at least a portion of the sample in the sample cell while an analyte detector analyzes the at least a portion of the sample; e. after the at least a portion of the sample is analyzed, directing the at least a portion of the sample into the container, wherein the container is configured to receive and store discarded biological material; and repeating at least a-e multiple times before disposing of the multi-use disposable sample element. - View Dependent Claims (16, 17, 18, 19, 20)
