56388284, Jun 17, 1997

Filed:

Aug 18, 1995

Appl. No.:

8/516660

Inventors:

Imants R. Lauks - Rockcliff Park, CA
Joseph W. Rogers - Doylestown PA

Assignee:

i-STAT Corporation - Princeton NJ

International Classification:

A61B 500

US Classification:

128763

Abstract:

A device and method for collecting a fluid sample and introducing it into a sensing device for real time analysis providing flexibility and simplicity in the way sample fluid sample collection is accomplished and cooperating with a disposable cartridge of the sensing device to permit quick and easy sample introduction and eliminate the risk of sample spillage, an exemplary embodiment of the collection device includes a capillary tube capable of receiving or drawing a fluid sample and introducing the fluid sample into the disposable cartridge, a reservoir chamber capable of receiving a fluid sample and a capillary tube holder capable of supporting one end of the capillary tube in the reservoir chamber to draw the fluid sample by capillary action. Alternative embodiments of the invention are used in combination with the variety of blood collection assemblies employed by the medical industry to collect fluid samples.

Appl. No.:

8/546797

Inventors:

Imants R. Lauks - Rockcliffe Park, CA
Raymond J. Pierce - Ottawa, CA
Joseph W. Rogers - Doylestown PA
Michael P. Zelin - Brooklyn NY

Assignee:

I-Stat Corporation - Princeton NJ

International Classification:

G01N 3350

US Classification:

436 68

Abstract:

Disclosed is an apparatus and method of equilibrating the dissolved gas composition of an aqueous fluid to reflect the predetermined gas composition contained in a gas equilibration reservoir. The equilibrated aqueous fluid can be used in a method of determining the concentration of a dissolved gas in a fluid sample. In one embodiment, the disclosed method is used to control the equilibrated gas composition of a calibrant fluid which, in turn, is used to measure the concentration of a dissolved gas, such as oxygen and carbon dioxide, in a sample fluid, such as whole blood.
