Abstract: A reference solution container for an analyzer for measuring gas and/or electrolyte levels in a fluid. The vessel includes a fluid container for holding a reference solution and a self-sealing fluid port for repeatedly accessing the reference solution in the fluid vessel by a fluid carrying device that is external to the reference solution container. The partial pressure of each gas in the reference solution within the fluid vessel is maintained at a substantially constant level.

Abstract: 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.

Abstract: A waste container for a blood analyzer or other fluid analysis medical device. The waste container includes a flexible waste bag having a gas vent that may include a gas permeable, but substantially fluid impermeable, material or fabric. The fabric allows gases to escape the waste bag, but substantially prevents fluids from escaping. The waste container also includes a moisture absorbent material, such as a polyacrylamide polymer, that converts waste fluid, such as blood, from the blood analyzer into a substantially solid material, such as a gel, as waste fluids enter the waste bag. As waste fluids enter the waste bag and are converted into a substantially solid material, expelled gases that form in the waste bag as well as gases entering the waste bag from the blood analyzer pass through the gas vent. The waste container can be used with a blood analyzer that analyzes blood gases and electrolytes.
