    摘要: The present invention includes apparatuses and methods for mitigating the effects of foreign interferents on analyte measurements. The present invention comprises several interferent mitigation steps. Examples include sample cleaning procedures, detection of the presence of interferents, determination of the identity of interferents, and modification or selection of a multivariate calibration model to mitigate the effects of one or more interferents on analyte measurements. The interferent mitigation steps of the present invention can be applied individually, and in some embodiments can be applied in combination. Some examples of relevant analyte measurements include the noninvasive determination of the presence or concentration of alcohol, glucose, urea, byproducts of alcohol metabolism, and substances of abuse.

    摘要: The present invention is directed to methods and apparatuses of medication management based upon active authorization of medication infusion by a clinician that can provide for effective management of an analyte in a patient's blood, reducing the opportunities for human error common with current manual systems while still placing final control of the medication management with the human clinician. For example, a semi-automated glucose management system can measure the glucose level in a patient's blood, recommend infusion parameters to a clinician who can authorize an infusion of glucose or insulin, and infuse the glucose or insulin into the patient.

    摘要: The use of an optical or other measurement in a blood access system enables the determination of a fluid sample appropriate for measurement on a real time basis. This information can be used to control the blood access system and related measurement processes. The determination can be based on, for example, at least one of: optical density, optical scatter, analyte level, temperature, the absolute level of any of the preceding, the stability of any of the preceding, the rate of change of any of the preceding, or the value of any of the preceding relative to another determination. The determination can be made using, for example, at least one of: electrochemical sensor, ion specific electrode, capacitance measurement, impedance measurement, inductance measurement, conductivity measurement, optical measurement, and ultrasound measurement. The present invention relates to determination of the quality of a biological sample in which determination of an analyte concentration is to be made, and various methods and apparatuses related thereto. An evaluation of sample quality can be made by monitoring the temporal changes in the sample properties or characteristics as the biological sample is procured or measured. The methods and apparatuses described herein can be used to evaluate the temporal characteristics of a sample during sample acquisition and/or during determination of the sample analyte or parameter of interest. The sample quality assurance methods and apparatuses described herein can thus be used to ensure that a valid sample has been procured by or presented to an instrument or measurement system for analyte determination, thereby preventing the measurement and reporting of analyte values for a sample that is unstable or otherwise non-representative of the biological system from which the sample was obtained.

    摘要: The present invention relates to a blood analyte measurement system for the procurement of blood samples for measurement of blood properties such as analyte concentration or analyte presence. A blood access system can be coupled with a measurement system such as an electrochemical sensor, and can also be used with other measurement modalities. Embodiments of the present invention can facilitate accurate measurement of blood glucose by the clinician in a sterile manner. Embodiments of the present invention can also enable the calibration of the sensor at one or more calibration points. One desired analyte of measurement is glucose for the effective implementation of glycemic control protocols. Embodiments of the present invention can also be used for the measurement of other analytes such as arterial blood gases, lactate, hemoglobin, potassium and urea. Additionally, embodiments of the present invention can function effectively on a variety of blood access points and specifically enables glucose monitoring in an existing arterial line that is already in place for hemodynamic monitoring. The present invention does not consume a significant amount of blood. Some embodiments of the present invention can re-infuse the blood into the patient, which can facilitate operation of the system in a sterile manner.
