A microcomputer based portable hemodialysis system.

A microprocessor controlled portable hemodialysis system (The Suitcase Kidney) has been designed and 18 dialyses have been successfully completed. The microprocessor is shown to be an improvement and simplification over the conventional discrete control mechanisms presently used to monitor and control system functions. The microprocessor is shown to reduce development time, complexity and size of the system while improving patient safety. A description of the system is presented emphasizing the functioning of the microcomputer.
