Patent number: 6794877Abstract: An apparatus and method for measuring conductance are provided. The method and apparatus are particularly well adapted for use with a removable or replaceable cartridge in a blood analysis system. The apparatus generally involves providing a system having a first, unfiltered, conductance measurement cell and a second, filtered, conductance measurement cell. The preferred method involves relating values measured in the two cells for a whole blood sample and for a known calibrant together, to obtain a value, for example hematocrit, for the unknown whole blood sample.Type: GrantFiled: July 31, 2002Date of Patent: September 21, 2004Assignee: International Technidyne CorporationInventors: Scott Everett Blomberg, Kee Van Sin, Brian Anthony Ott

Publication number: 20040163970Abstract: A cartridge for analyzing a bodily fluid for use with an analytical device includes a base structure, a sensor arrangement, a pump arrangement, and a pump control arrangement configured to selectively operate the pump when the cartridge is operatively positioned in the analytical device. A system for analyzing a bodily fluid includes an analytical device with a cartridge-receiving receptacle and a cartridge operatively and removably mounted in the cartridge-receiving receptacle. The cartridge includes a sensor arrangement and a pump. The analytical device includes a pump control arrangement to selectively operate the pump. A method of analyzing bodily fluid includes inserting a cartridge into an analytical device, dispensing a sample into the cartridge, sensing the fluid with the cartridge, and allowing the analytical device to automatically pump a calibration fluid over sensors in the cartridge.Type: ApplicationFiled: February 20, 2003Publication date: August 26, 2004Applicant: Diametrics Medical, Inc.Inventors: Kee Van Sin, Martin Gaines Hieb, James Donald Kurkowski, Scott Everett Blomberg

Publication number: 20030224523Abstract: A cartridge for analysis of fluid samples useable with an analyzer device includes an arrangement to selectively control fluid flow within the cartridge. One type of cartridge includes a fluid channel. A sensor arrangement is oriented within the fluid channel and includes at least one dry-stored sensor and at least one wet-stored sensor. The cartridge may include a first port. In some instances, the cartridge can include a second port. In some instances, the cartridge can include a third port. In some implementations, a cartridge includes a fluid reservoir in fluid communication with a port on the cartridge. The fluid reservoir defines a fluid passage and a fluid dispenser actuator. The actuator includes an over-center engageable button depressible to initiate fluid flow from an internal volume in the fluid reservoir and through the fluid passage and through the port into the sensor arrangement on the cartridge. Methods for analyzing, calibrating, and using the cartridge are provided.Type: ApplicationFiled: May 30, 2002Publication date: December 4, 2003Inventors: John Herbert Thornberg, Kee Van Sin, Martin Gaines Hieb, Ronald William Sand, Scott Everett Blomberg
