Abstract:
The present invention relates generally to systems, apparatuses, and methods for obtaining a fluid sample from a patient. In particular, the present invention relates to a various types of fluid access interfaces for enabling contact between a patient blood sample and blood parameter sensors for the measurement of physiological parameters and blood constituents.
Abstract:
The present invention is directed towards apparatuses and methods for the automated measurement of blood analytes and blood parameters for bedside monitoring of patient blood chemistry. Particularly, the current invention discloses a programmable system that can automatically draw blood samples at a suitable programmable time frequency (or at predetermined timing), can automatically analyze the drawn blood samples and immediately measure and display blood parameters such as glucose levels, hematocrit levels, hemoglobin blood oxygen saturation, blood gases, lactate or any other blood parameter.
Abstract:
The present invention is a programmable, automated device for the measurement and analysis of blood analytes and blood parameters. The device components are combined in a single apparatus and either programmed to initiate automatic, periodic blood sampling or initiate automatic blood sampling via operator input. The device operates automatically to draw blood samples at suitable, programmable frequencies to analyze the drawn blood samples and obtain the desired blood readings.
Abstract:
A method determines an analyte concentration in a sample including the analyte and a substance. The method includes providing an absorption spectrum of the sample. The absorption spectrum has an absorption baseline. The method further includes shifting the absorption spectrum so that the absorption baseline approximately equals a selected absorption value in a selected absorption wavelength range. The method further includes subtracting a substance contribution from the absorption spectrum. Thus, the method provides a corrected absorption spectrum substantially free of a contribution from the substance.

Abstract:
An analyte concentration monitoring system having network-based communication features which provide a link between an analyte detection system and a centralized computer. The analyte detection system has a processor that calculates analyte concentration in accordance with software executable by the processor. Under certain conditions, the software needs to be updated. Accordingly, when the analyte detection system is connected to the centralized computer, the centralized computer determines whether a software update is needed. If a software update is needed, then the centralized computer conveniently provides the software update to the analyte detection system without intervention from a user.

Abstract:
The present invention is a programmable, automated device for measurement and analysis of blood analytes and blood parameters. The device components are preferably combined in a single housing and either programmed to initiate automatic, periodic blood sampling or initiate automatic blood sampling via operator input or in response to a predefined event or in response to a signal from another instrument. The device operates automatically to draw blood samples and analyze the drawn blood samples to obtain the desired blood readings.
Abstract:
A substantially automatic blood parameter testing apparatus for obtaining a blood sample and determining the concentration of at least one analyte is connected to a venous or arterial access line and further comprises a pump fixedly attached to a tube originating from the vascular access point; a valve fixedly attached to the tube and located above the pump mechanism; at least one measurement element; a needleless port; and an electronic meter. In addition, the automated blood parameter testing apparatus may be integrated into a complete system, further including a monitor and a central monitoring station.
