Abstract

The application discloses a hospital data handling system which transmits and receives all message information normally required in hospital operations and automatically withdraws from the transmitted messages all data necessary for establishing such items as bed status data, inventory records, patient charges, etc. The system input is derived from permanent punch cards containing all necessary message and control information and disposable punch cards containing variable data, such as patient identifying cards made, for instance, when a patient is admitted. A printer and a card reader are located at each message originating location or station in the hospital to provide messages which are placed in a delay line input storage shared by a group of card readers. As the delay line data is transferred to a core storage unit shared by all the readers, a printer selector checks each message for printer addresses, and a control decoder checks for the type of operation to be performed on the message. If only output recording is required and if all addressed printers are available, the message is cleared from the delay line storage and read out from the core storage unit to the printers through individual buffer tracks on a drum in a central processor. Alternatively, if all the printers are not available, the message is retained in the delay line until the printers are available. If the control decoding indicates that data operations are to be performed on the message, the message is sent from the core storage unit to the drum in the central processor.
