[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a medical information management system, and in particular, the present invention relates to a medical information management system, and in particular to normal X-ray images, X-ray C7 images, ultrasound images, electrocardiograms, etc. of human organs and tissues. Visual information such as heartbeat sounds (heart sounds), acoustic information such as activity of other organs and tissues (hereinafter referred to as activity sound information) are recorded as a medical treatment layer (medical history) on a recording medium (optical disk, etc.) The present invention relates to a medical information management method in which each piece of information is stored in advance and reproduced as necessary to perform examinations, treatments, medical history management, etc.

[Conventional technology]

It is known that in medical diagnosis, human organs, blood vessels, and other body tissues are observed using X-ray images, X-ray C7 images, ultrasound images, electrocardiograms, etc., and these are used for diagnosis and treatment. .

Image information and activity waveform information are compressed/multiplexed and recorded using appropriate means, thereby making it possible to relatively increase the recording capacity of the optical disc.

[Problem to be solved by the invention]

The conventional medical information management system described above does not take into account the storage of organ activity sound information that is used audibly, such as heart sounds.

Additionally, as mentioned above, it is also possible to create an individual medical layer file that each patient saves as their medical history by chronologically filing the diagnosis information of each patient in the order of diagnosis. However, the medical information that can be stored is limited to visual information.

The purpose of the present invention is to simultaneously file audio information in addition to visual information as medical information for each individual patient, thereby providing doctors with more accurate diagnostic information and providing medical history of each patient. An object of the present invention is to provide a medical information management method that allows easy acquisition of medical information.

[Means to solve the problem]

The above purpose is to record image information of organs, etc. and visual information such as their activity waveforms, as well as their activity sound information, as one unit of recording on a recording medium as medical information, and to reproduce the visual information from the recording medium and display it visually. It is characterized in that the activity sound information is displayed on the sound display means and simultaneously reproduced so that it can be heard on the sound display means.

[Effect]

By displaying visual information about organs on a visual display means (such as a CRT monitor) and simultaneously playing back the activity sounds of the displayed organs on an acoustic display means, it is possible to accurately grasp the past state of the organ, and also to understand the state of the organ over time. It becomes possible to comprehensively know the patient's condition (medical history, treatment history).
