Abstract
A method of using a multi-compartment fluid assembly for calibrating an apparatus external to the assembly, while conveniently maintaining sterility. The method includes providing calibration fluid in a closed calibration container disposed within a bag that includes a connector for conveying fluids between the interior of the bag and a conventional intravascular tube. In use, fluids may be directed through the external apparatus and the intravascular tube and into the bag's interior. At an appropriate time, the calibration container is opened and the calibration fluid is withdrawn from the container to the intravascular tube, through the connector, without mixing the calibration fluid with any fluids in a remaining volume of the bag. Subsequently, the calibration fluid is transferred from the intravascular tube to the bag's interior, again through the connector.
