Reflectance based methods and devices are provided for determining the concentration of an analyte in a fluid sample. In practicing the subject methods, a fluid sample is applied to a matrix impregnated with a signal producing system. The signal producing system produces a detectable product in an amount proportional to the amount of analyte in the sample. A surface of the matrix is then illuminated and a reflectance measurement is obtained therefrom, generally following a predetermined incubation period. An optical component, preferably the illumination or light detection means, is also employed to obtain a temperature value corresponding to the ambient temperature of the matrix. The analyte concentration of the sample is then obtained from the reflectance measurement using an algorithm that employs the optical component derived temperature value. The subject methods and devices are suited for use in the detection of a variety of different types of fluid analytes, and are particularly suited for use in detecting the concentration of glucose in whole blood.

Abstract:
Data entry and display apparatus and methods that provide greater efficiency in data processing devices. The apparatus comprises a keypad with a plurality of first keys and plurality of secondary keys, the first keys each having at least one primary alphanumeric symbol and at least one of the first keys having a secondary alphanumeric symbol associated therewith, the first key with the secondary symbol being operable to selectively display the secondary alphanumeric symbols in association with the second keys. The apparatus may further comprise a display, which may be embodied in a common touch screen user interface with the keypad. The methods comprise actuating one of the first keys on the keypad and displaying a set of secondary alphanumeric symbols in association with the secondary keys, and selecting the primary alphanumeric symbol associated with the first key or selecting one of the set of secondary alphanumeric symbols by actuating one of the second keys. Selection and actuation of appropriate combinations of first and second keys allows entry of any character string.

Apparatus And Method To Test For Valve Leakage In A Pump Assembly
Michael W. Lawless - Boulder Creek CA Walter L. Jimison - Palo Alto CA Giovanni Pastrone - Los Gatos CA Anthony C. Yung - Milpitas CA
Assignee:
Abbott Laboratories - Abbott Park IL
International Classification:
F04B 5100
US Classification:
417 63
Abstract:
Apparatus and method for determining leakage, particularly of valves, in a pumping cassette. A cassette (70) includes a primary valve (34) and a secondary valve (36), which may be selectively activated to control the source of fluid input to the cassette. The cassette also includes an inlet valve (48) and an outlet valve (56) disposed on each side of a pumping chamber (52). Downstream of the outlet valve is disposed a pressure sensor (60) which produces a signal indicative of the pressure of fluid within the cassette at that point. The cassette also includes an air-in-line sensor (40), disposed between a manifold line (38) that connects the primary and secondary valve in fluid communication with an air trap reservoir (44). Leakage in the inlet or outlet valves is detected by closing both valves, pressurizing fluid in the pumping chamber for a predetermined period of time, and then opening the outlet valve. If a pressure pulse having an amplitude less than a predetermined level is detected downstream of the outlet valve when it is opened, either the inlet or outlet valve has leaked.
