In hospital, various parts such as medical examination, medical examination support, business management and the general management are working a patient medicine, a hospital operation with organic cooperation each other. The bigger the size of hospital and the information of data causes more complex in the communication of each part in the hospital so, various computational systems have introduced. The introduction of this computational systems offers patients a good quality of service, medical institution could makes effective and systematic management of medical treatment information, so there is a improvement of business operation. This causes a reduction of operation expenses and offering a good quality of services to patients.
The development of network and equipment of communication get digital images from image equipment, manage, store and the distribution of this images makes x-ray checking of diagnosis and reference from image display monitor in the use of PACS. PACS appears one another method about information reception systems in the hospital as a complement of HIS which based on existing message information. Like this, together with arrival of informative age, the computational system is appeared important facilities in the hospital which enlarge the chance of the medical benefits to patient and offer the best medical services. However, to use this computational system, there should have working place with equipment and program related to computational system in the hospital, so this called static computational system. Even if there made computational systems there is a medical member's inadequate medical recording system and in the opposition of on-line environment there is a lot of hand-work after writing a hand-writing before computerization input is required. In this paper, as the development of wireless-network equipment and generalization of PDA, using PDA, embodies PDA client that makes possible to search and renew the data of HIS/ RIS/PACS and embodies hospital managing Agent that makes possible to link with PDA to database in the hospital when you are moving another place. Hereby, doctor can modify patient's personal information, search patient's medical information and take care of his own business easily, so we want to improve inadequate treatment recording system of medical members.
