US Patent:

8518237, Aug 27, 2013

Filed:

Sep 14, 2009

Appl. No.:

13/119990

Inventors:

Andy Chan - Franklin MA, US
Lawrence Milesky - Needham MA, US

Assignee:

Siemens Healthcare Diagnostics Inc. - Tarrytown NY

International Classification:

G01N 27/26
G01N 27/404

US Classification:

205783, 73 2321, 73 101, 205793, 204415

Abstract:

The service life of amperometric electrochemical oxygen sensors is increased by operating the electrodes of such sensors at a polarization voltage suitable for measuring the oxygen content of samples only during calibration or when measuring such samples and thereafter modulating the polarization voltage to a lower voltage such that substantially no electrical current is produced by the electrodes.

Filed:

Apr 20, 1979

Appl. No.:

6/031705

Inventors:

James E. Nicholson - Lincoln MA
Lawrence Milesky - Needham MA

Assignee:

Codman and Shurtleff, Inc. - Randolph MA

International Classification:

A61B 500

US Classification:

128748

Abstract:

A pressure monitoring system for use with an electrofluidic device for sensing pressure includes a pump for supplying fluid to the electrofluidic sensing device. An electrical switching circuit controls the supply of fluid to the sensing device and is responsive to the external pressure level applied to the sensing device; this circuit also cyclically causes the supplied pressure to vent when the pressure of supplied fluid inside the sensing device is substantially equal to the applied external pressure, and then start the fluid supply to the device over again. This system further includes a measuring element for detecting the pressure level of the supplied fluid, and a digital meter for displaying the analogous detected pressure level during supply of the fluid.

Assignee:

International Classification:

G01N 3500

US Classification:

422 81

Abstract:

An analysis system for analyzing a biological fluid or the like for a constituent of the interest includes metal body structure with sample flow path channel structure that serially interconnects heater chamber structure, recess structure for receiving a reaction chamber cartridge and an analysis region to which a measuring system is coupled. The reaction chamber cartridge preferably includes reaction chamber structure with an immobilized enzyme in the reaction chamber that is capable of converting the constituent of interest to a constituent detectable by the measuring system. Cooperating with the metal body structure is a transparent face plate structure which permits visual observation of the sample flow path in the metal body structure. Thermally coupled to the metal body immediately adjacent the analysis region are a temperature sensor that provides a temperature signal to a control unit and a thermal source that receives control signals from the control unit as a function of signals from the temperature system for stabilizing the temperature of the metal body structure (including the reaction chamber structure, the heater chamber and the analysis region) at a desired analysis temperature.

Abstract:

Method and apparatus for sensing fluid interface(s) in a complex fluid such as centrifuged blood, includes a sensing assembly with a microwave source and a microwave sensor positioned in spaced opposed relation, the microwave source and sensor defining a microwave propagation path. Relative motion is induced between the sample container and the microwave energy propagation path in the region between the source and sensor in a direction that intersects and is essentially perpendicular to the microwave energy propagation path; and processor apparatus responsive to the scanning apparatus and the modification in microwave energy sensed by the microwave sensor provides an indication(s) of the location(s) of a fluid interface(s) in the container.
