20160085918 | MEDICAL ASSISTANCE DEVICE, OPERATION METHOD AND OPERATION PROGRAM FOR MEDICAL ASSISTANCE DEVICE, AND MEDICAL ASSISTANCE SYSTEM - There are provided a medical assistance device, an operation method of a medical assistance device, a non-transitory computer-readable recording medium, and a medical assistance system capable of improving work efficiency by reducing the burden on a user. When a request receiving unit has not received an input of a designated data range or when there is a difference between the designated data range and a first recommended data range, an automatic data range setting unit reads a second recommended data range of the latest event from a second recommended data range list. The medical data acquisition unit extracts medical data corresponding to the second recommended data range from the medical data in the entire course of treatment for the patient. The program control unit executes a diagnostic assistance program by giving medical data corresponding to the second recommended data range as input data, and outputs diagnostic assistance information. | 03-24-2016 |
20160085928 | MEDICAL ASSISTANCE DEVICE, OPERATION METHOD AND OPERATION PROGRAM FOR MEDICAL ASSISTANCE DEVICE, AND MEDICAL ASSISTANCE SYSTEM - There are provided a medical assistance device, an operation method of a medical assistance device, a non-transitory computer-readable recording medium, and a medical assistance system allowing a user to use a diagnostic assistance program with confidence. A comparison determination unit compares a designated data range, which is designated as a range to be used for input data of a diagnostic assistance program, with a recommended data range, which is set for each diagnostic assistance program and is recommended as a range to be used for input data. The comparison determination unit outputs information regarding surplus data, which is data outside the recommended data range in the designated data range, and information regarding missing data, which is data outside the designated data range in the recommended data range. A difference information output unit outputs the information of the surplus data or the missing data as difference information. | 03-24-2016 |
20160085929 | MEDICAL ASSISTANCE DEVICE, OPERATION METHOD AND OPERATION PROGRAM FOR MEDICAL ASSISTANCE DEVICE, AND MEDICAL ASSISTANCE SYSTEM - There are provided a medical assistance device, an operation method of a medical assistance device, a non-transitory computer-readable recording medium, and a medical assistance system capable of improving work efficiency by reducing the burden on a user. A recommended data range output unit receives a program ID of a diagnostic assistance program from a request receiving unit. The recommended data range output unit reads a recommended data range corresponding to the received program ID from a recommended data range list, and transmits the recommended data range to a screen generation unit. The screen generation unit includes a check box and a period designating bar for designating designated data items and a designated data period, which form a designated data range, and generates a medical data display screen on which displays of recommended data items and a recommended data period, which forms a recommended data range, are made. | 03-24-2016 |
