A FAULT-RESISTANT REFRIGERATOR FOR BIOLOGICAL MATERIALS

摘要

A protective refrigerator for storing material that can tolerate a limited temperature range includes a back-up thermostat set to open and close over a range slightly larger than an existing thermostat, yet still within that limited temperature range. The refrigerator has an indicator reporting relevant storage conditions to the exterior. An embedded computer for storing data and reporting data is optional, and may use a local or wider communications network such as the Internet. If present, the computer may be made to print certificates on a local or remote printer that verify proper storage conditions such as for vaccines.
