Blood refrigerator/ incubators are devices intended to be used in the blood transfusion medicine for the support on the diagnosis, prevention and treatment of diseases or injuries by keeping whole blood or blood components at a protective and stable temperature between 2°C to 6°C, or platelet components between 20°C to 24°C, until they are ready for use. They are electrically-powered devices and include an active system to regulate the temperature, handles and/or wheels for transportation, and alarms which signal unintentional changes in temperature and power failures.
