Abstract
Abstract This invention is an automatic cleaning unit for emptying, cleaning and sterilizing bedpans in hospitals. The nurse puts the full bedpan straight into the cabinet and an automatic cleaning cycle is initiated by the closing of the door, which first turns the pan over so that the contents falls into a collecting chamber from which it runs to sewage. Then cold water is sprayed on to the surfaces of the pan and it is turned upright and sterilizing fluid is directed at its surfaces for sterilizing it and drying it.
