AUTOCLAVE DEVICE AND PTC HEATING ARRANGEMENT FOR USE THEREWITH

摘要

An autoclave type sterilization device employing positive temperature coefficient (PTC) thermistor heating elements (11) and improved heating arrangements (10) therewith. The heating arrangements include radiation members (12, 13) in thermal contact with both sides of the PTC heating elements (11) which are both in thermal contact with the surface of the autoclave chamber (41) thereby providing fast and efficient heat transfer thereto. The PTC thermistor-based heating arrangements (10) may also be used for retrofitting existing autoclave type sterilization devices.
