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.

Claims

1. For facilitating collection of a fluid sample into a fluid sample collection device including a capillary tube having an introduction end, the capillary tube supported in an opening in a reservoir chamber housing, an adapter comprising:

a body having a through-bore having a first end and a second end and an inner surface and an outer surface, the outer surface at the second end of the through-bore formed to provide a male luer fitting, the inner surface adjacent the second end of the through-bore formed to complement the outer surface of the capillary tube adjacent the introduction end;

a port formed adjacent the first end of the through-bore, the port being sized to form an air-tight relation with the opening of the reservoir chamber housing; and

an air passage through the body separate from the through-bore adjacent the first end of the through-bore.

2. An adapter as in claim 1 wherein the port includes securing means to secure the collection device to the component.
