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.
