In the figure, an X-ray apparatus 51, a CT apparatus 52, an MR apparatus 53 (hereinafter, referred to as a modality apparatus 50), an image server 54 and an image viewer 55 are connected via an information network L. The finding station 56, the finding server 57 and the printer 58 are also connected to the same information network L.

In the medical finding management system having such a configuration, the modality device 50 generates medical image data obtained by converting an affected part image of a patient into electronic data, and outputs the medical image data to the image server 5.
Reference numeral 4 stores the medical image data together with patient information including a patient name and a patient number.

The medical image data stored in the image server 54 can be displayed on an image viewer 55. The user can display the medical image data on a finding station 56 while referring to the affected part image displayed on the image viewer 55. Enter the finding data from the finding data input screen. The input finding data is stored in the finding server 57 together with the patient information.

In such a medical information system, the image server 54, the finding server 57, and the finding station 5
6 is connected by the information network, for example, as shown in FIG. 6, the medical image data 111 and 112 are pasted and saved on the finding data on the finding data input screen 110 displayed on the finding station 56. Is possible.

In such a medical information system,

The search can be performed to display medical image data of a target patient on the screen of the finding station 56 or the image viewer 55.

As described above, in the medical field in recent years, information networking of medical data has been advanced. Along with this, there is an increasing demand to connect the physiological examination system to a medical information system as shown in FIG. 5 and to share physiological examination data such as an electrocardiogram and an electroencephalogram on the information network L.

However, in the conventional physiological examination system,
The communication interface used for the electrocardiograph, the electroencephalograph, the data storage device 30 and the display device 40 is RS-232C or G
There is a problem in that it is difficult to connect them to an information network because they are P-IB or unique to the manufacturer.

Further, as described above, in the conventional physiological examination system, the electrocardiogram and the electroencephalogram waveform generated by the electrocardiograph and the electroencephalograph have been devised independently by the respective manufacturers. It is necessary to distribute the information on the information network without losing the image form, but the compression technology used for the electrocardiograph and electroencephalograph is also a unique one that has been variously devised by the manufacturers, as described above. Therefore, it was not possible to use a general-purpose decompression technique to decompress this and reproduce an electrocardiogram or an electroencephalogram waveform.

Therefore, even if the data storage device 30 is simply connected to the information network and the compressed data stored therein is read into the terminal device, it is decompressed and an electrocardiogram or an electroencephalogram waveform is displayed on the screen of the terminal device. There was a problem that it could not be reproduced.

The present invention solves the above problems,
