Description

  The present invention relates to a medical information system, a medical information reference method, and a medical information input method that prevent leakage and tampering by limiting medical information to be referred to or input.

  In recent years, a medical information system including a medical information server that stores medical information obtained from a diagnosis target patient and a medical information viewer connected to the medical information server via a network has been widely used.

  The medical information includes X-ray CT apparatus, MRI apparatus, X-ray diagnostic apparatus, and image data obtained by an image diagnostic apparatus such as an ultrasonic diagnostic apparatus, and a biological information measuring apparatus such as an electrocardiograph or an electroencephalograph There are electronic medical records in which biological information measurement data obtained by the above, specimen examination data such as blood and urine obtained by a specimen examination apparatus, and findings reports on these data are collected. In addition, patient information including a history of the patient and the like, an operation consent form, etc. are digitized and stored in the medical information server.

  In this medical information system, since the medical information of the patient is initially stored in the medical information server dedicated to the doctor, the doctor uses the medical information viewer directly connected to the dedicated medical information server to obtain the desired medical information. There was a restriction that it had to be referenced.

  As a technique for solving such a problem, a plurality of medical information viewers and a plurality of medical information servers are connected via a network, and the medical information stored in the medical information server is processed at high speed for each medical use. A method has been devised in which desired medical information can be referred to by using any medical information viewer by converting to the information viewer display method (for example, see Patent Document 1).

According to such a medical information system, a doctor can refer to image data, biological information measurement data, and the like using an arbitrarily selected medical information viewer, and the restriction on the reference location is greatly reduced.
