Abstract

PROBLEM TO BE SOLVED: To prevent paper sheets from being wasted by reusing medical chart information paper sheets of patients which are already printed when the updated medical chart information is printed. SOLUTION: A conventional electronic medical chart system prints contents stored in a device as they are. The medical chart information is updated at every time when medical examination is done. For printing, a form which is printed last is discarded and a new form needs to be printed. For the purpose, differential operation between image data of medical chart information of a patient which is already printed and the medical chart information to be printed is carried out and the resulting image data are extracted as an updated part to print only the updated part on the form used to print the last medical chart information of the patient.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic medical chart apparatus for creating, storing, and printing by electronic means. When printing updated medical chart information on a printer, it is possible to reuse already printed paper. The present invention relates to an electronic medical record device that can be used.

[0002]

2. Description of the Related Art Heretofore, doctors have generally written medical records on paper using a writing instrument such as a pen. In recent years, with the development of computer technology, a system for creating this medical record electronically has been attempted. In the creation of an electronic medical record, regarding the input of a patient's symptoms, observation findings, etc., a preset content is selected and input. Has been proposed. Japanese Patent Application Laid-Open No. 4-199271 is related to this type of apparatus.

[0003]

The conventional electronic medical record system prints the contents stored in the apparatus as it is in printing. The medical record information is updated for each consultation, and therefore, in printing, it was necessary to discard the previously printed sheet and print on a new sheet. In view of the above, an object of the present invention is to reuse a patient's chart information sheet that has already been printed, thereby preventing wasteful consumption of the sheet.

[0004]

In order to achieve the above object, medical record information is stored in the form of image data, and a difference calculation between the printed medical record information of the patient and the image data of the medical record information to be printed from now on is performed. Then, the resulting image data is extracted as an updated portion, and only the updated portion can be printed on the sheet used for printing the patient's previous chart information.

[0005]

Embodiments of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 shows an embodiment of an electronic medical record apparatus according to the present invention.

In the embodiment, a tablet 1 for inputting and simultaneously displaying medical chart information and a stylus pen 2 as input means are provided.
The system includes a client computer 3 for controlling input / display of medical record information, an optical reader 4, a printer 5 for printing medical record information, an external storage device 6, and a computer 7 for a server. Tablet 1, stylus pen 2,
The client computer 3 receives a medical facility,
It is also conceivable that they are placed in the examination room.

As shown in FIG. 2, the tablet 1 displays a format 8 of a medical chart used by the doctor (or hospital), and accepts or displays the patient's name, patient number, etc. with the stylus pen 2 by the doctor. Enter information.

The doctor writes necessary medical record information such as the patient's condition and treatment on the tablet 1 using the stylus pen 2.

The doctor clicks the save button 9 displayed on the tablet 1 with the stylus pen 2 at a desired time during the description of the medical chart, and the medical chart information described by the stylus pen 2 is transmitted to the server computer through the client computer 3. It can be sent to the computer 7 and stored in the form of image data. When the save button 9 detects a new input, the background color is changed by the client computer 3 to notify the doctor that unsaved data exists.

Next, a process for printing the medical record information created by the electronic medical chart apparatus configured as described above will be described with reference to a flowchart shown in FIG.

When printing, the print button 10 is clicked with the stylus pen 2. If the patient chart information is printed for the first time, step A proceeds to the “YES” side, and the image data of the chart information is printed as it is in step C, and after printing is completed, a copy of the chart information is created in step D. When the copied medical record information is displayed on the tablet 1, the background color of the print button 10 is changed, and the user is made aware of the change. Also, in the case of printing the previously recorded chart information, step A proceeds to the “NO” side, and in step B, the difference between the image data copied in the previous printing of the patient chart information and the image data to be printed this time is calculated. In step C, only the difference portion is printed, and in step D, a copy of the entire chart information of the patient including the difference is created.

[0013]

By using the method of the present invention, when the updated chart information is printed, the already printed chart information sheet of the patient can be reused, and wasteful use of the sheet can be prevented. Furthermore, since the medical chart information is handled as image data, it can be updated on the electronic medical chart system by inputting a conventional paper medical chart created using a writing instrument such as a pen with an optical reader,
The paper chart can also be used for printing.
