A calibration fluid cartridge for a medical device, such as a blood analyzer. The cartridge includes at least one calibrant bag that is filled with a flexible calibration fluid and a flexible waste bag for holding fluid waste from the blood analyzer. The calibrant bags contract as calibration fluid exits the bags, leaving a void in the cartridge that is filled by the waste bag, which expands with waste fluids as the calibrant bags contract. Thus, the cartridge can be made compact and light-weight, making it particularly suited for use in a portable blood analyzer. The calibrant bags have fluid ports with self-sealing valves and a flange to secure them within the cartridge, as well as a compliant member for facilitating a secure, fluid-tight seal between fluid fitting on the blood analyzer and the calibrant and waste bags. The calibrant bags can be directly coupled to the blood analyzer to reduce diffusion of gases from the calibrant bags.

[ What is claimed is:] [1.] A fluid communication port for a calibration bag coupled to a blood analysis device, the blood analysis device having a calibration bag locating element for coupling a calibration bag that contains a blood analysis calibration fluid to the blood analysis device, the blood analysis device also having a flow fitting, the communication port comprising:a. a port body having a fluid communication path extending throughout the length of the port body, the port body having a fitting end for accepting the flow fitting of the blood analysis device and a bag end engaging the calibration bag that contains the blood analysis calibration fluid;b. a self-sealing valve, located substantially within the fluid communication path, that (1) substantially prevents flow of blood analysis calibration fluid from the calibration bag and of fluid into the calibration bag unless the flow fitting is engaging the self-sealing valve and (2) substantially prevents escape of gas from the blood analysis calibration fluid in the calibration bag; andc. a flange, coupled to the port body, for securing the fluid communication port to the calibration bag locating element of the blood analysis device.
