Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a portable information recording medium for a system for managing personal information such as medical information.

[Conventional technology]

In recent years, the amount of information has increased enormously in many fields, and the need for efficient information management has increased. For example, in a hospital, it is not only necessary to maintain medical records for each patient, but also to store diagnostic photographs from X-ray diagnostic equipment and ultrasound diagnostic equipment, as well as CT (computer tomography) tomography images processed by computers. It is also necessary to save image information from diagnostic equipment such as The amount of such information increases as the number of patients increases, and if the past information of each patient is stored and the medical history of each patient can be known, the amount of information becomes extremely large.

For this reason, large hospitals have adopted a system in which this information is categorized by patient and centrally managed in a single file, and when the patient is specified, information for the specified patient can be searched. .

[Problem to be solved by the invention]

However, when the amount of information becomes extremely large, it takes a lot of time to search for information for the necessary patient.
Moreover, each time a patient is examined, information about the patient must be retrieved from this huge file over a long period of time.

Further, even if the patient is diagnosed using an X-ray diagnostic apparatus at the hospital where the patient resides, depending on the diagnostic results, a more detailed examination may be requested at another hospital. In such a case, the other hospital may perform the same diagnosis on the patient again as at the previous hospital, and perform a detailed examination based on this diagnosis.

In this way, the same patient may undergo X-ray diagnosis multiple times for the same medical condition, which is undesirable because the amount of X-ray exposure increases.

Furthermore, patients may go to a different hospital than they have previously visited even if they have the same disease. In such cases, the patient has no choice but to learn about the patient's past medical history directly from the patient at the new hospital, and the reliability of the patient's medical history as diagnostic data becomes an issue.

Moreover, in devices that search for desired image information from centrally managed files and display the image, it is necessary to store a processing program for processing this image information, and various image display methods have been incorporated. If this is attempted, the scale of the processing program for this will increase and a large capacity memory will be required as the program memory.

An object of the present invention is to provide a portable information recording medium for an information management system that solves these problems and allows all necessary information to be obtained accurately and quickly even when the amount of information is enormous. It is about providing.

[Failure to solve the problem]

In order to achieve the above object, the present invention records information for each individual on a separate portable information recording medium so that the information recording medium is owned by the individual, and furthermore, the information recording medium is Also records index information representing the .

[Effect]

Since information for each individual is recorded on an information recording medium, a huge amount of information can be distributed and the amount of information to be searched can be greatly reduced.Moreover, by displaying index information as an image, the information The correspondence between the owner of a recording medium and the information recorded on the information recording medium can be accurately confirmed, and therefore information retrieval can be executed quickly and accurately.

〔Example〕

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

FIG. 1 is a diagram schematically showing a user area of an embodiment of a portable information recording medium for an information management system according to the present invention.

This portable information recording medium for the information management system (hereinafter simply referred to as a recording medium) is an optical disc or the like, which is owned by an individual and contains image information such as X-rays and CT scans based on the owner's past diagnosis (hereinafter referred to as a recording medium). (referred to as personal medical information)
is recorded.

That is, in FIG. 1, the recording medium is provided with a user area where the user can record and reproduce information, and personal medical information A, B, C, . . .
. . . Directory information a, b, c, . Information such as a facial photograph representing the person (hereinafter referred to as personal index information) is also recorded. The directory information consists of information such as the information name of the personal medical information, the start address of the recording position in the user area, the data length, etc., and the date. In Figure 1, directory information a is the information for the personal medical information Similarly, the directory information @b, c, etc.
... is personal medical information B, C, etc., respectively.
This corresponds to Here, personal medical information is A.
B.

C1......... in the direction of the arrow (for example,
If the recording medium is an optical disc, information is recorded from the inner circumference to the outer circumference of the disc, and along with this, directory information is also recorded.

The information is recorded in the order of b, c, etc. in the direction of the opposite arrow (for example, if the recording medium is an optical disc, from the outer circumference to the inner circumference), but each piece of information is recorded on the head. If the recording medium is an optical disc, it goes without saying that information is recorded in the scanning direction (from the inner circumference to the outer circumference).

FIG. 2 is a block diagram showing a specific example of the information management system using an optical disk as a recording medium shown in FIG. 1, in which l is a host computer, 2 is a buffer memory,
3 is a disk drive device, 4 is an optical disk which is a recording medium shown in FIG. 1, 5 is a display device, 6 is a center system, and 7 is a file.

Here, a specific example will be explained using a medical institution such as a hospital, but the system using the present invention is not limited to this.

In FIG. 2, host computer 1. The buffer memory 2, disk drive device 3, and display device 5 are installed on the desk of each doctor in a hospital as a diagnostic device, and the optical disk 4 is owned by the patient. Each examination device is connected to a center system 6 that has a file 7, and this file 7 stores all the medical information (image information such as X-rays and CT images) obtained so far for each patient. Next, the operation of this specific example when using the optical disc having the user area shown in FIG. 1 will be explained using the flowchart in FIG. 3.

At the hospital, the doctor receives the optical disc 4 from the patient and inserts it into the disc drive device 3 (step 101).
, when a predetermined startup operation is performed, the host computer 1 sends predetermined information to the disk drive device 3 and performs initialization processing of the disk drive device 3 (step 102).
). After this initialization process is completed, the disk drive device 3
When a response is received from the host computer 1, the host computer 1 activates the disk drive device 3 to read personal index information from a specific area of the user area (FIG. 1) on the optical disk 4. The read personal index information is processed by the host computer 1 using the buffer memory 2, and is sent to the display device 5 as an image signal.
is supplied to As a result, in the display device 5,
An image such as a face photograph representing the true owner of the inserted optical disc 4 is displayed (step 103).

If the displayed image is a facial photograph, the doctor visually compares this with the patient who brought the optical disc 4 (step 1).
04). When the two match, it means that the medical information of the patient who brought the optical disc 4 has been recorded, and the user performs a predetermined operation to search for and reproduce the desired personal medical information.

This search is performed as follows. For example, in FIG. 1, if personal medical information A and C are X-ray photographs, and personal medical information B is a CT scan, the host computer 1 can be connected to the disk drive by the doctor's instruction to input the information name "X-ray photograph". The device 3 is controlled to read directory information from the optical disc 4. When directory information a is read, the information name matches the specified input "X-ray photograph", so personal medical information A of this directory information a
The recording position information is detected, and based on this, the personal medical information A is read out from the optical disc 4. The personal medical information @A obtained in this manner is processed by the host computer 1 in the same manner as the personal index information, and is supplied to the display device 5 as an image signal. therefore,
The display device 5 displays an X-ray photograph. By the doctor performing the prescribed operations without changing the information name specification,
The personal medical information of each X-ray photograph is sequentially reproduced from the optical disc 4, and each X-ray photograph is displayed on the display device 5 in sequence. Of course, by specifying the date, it is also possible to search for and display X-ray photographs taken on the specified date, and personal medical information from the examination results on that day can also be recorded on the optical disk 4 at the time of diagnosis by the doctor. . In this way, the patient can be diagnosed based on the display screen of the display device 5 (step 10).
5).

After the diagnosis, when the doctor performs a predetermined termination process operation, the host computer 1 performs the termination process (step 106) and ejects the optical disc 4 from the disk drive device 3 (
Step 107).

Search for personal medical information in File 7 of Center System 6
The same can be done for .

When there is a large amount of personal medical information, it is not possible to record all of it on the optical disk 4, and the newest information is recorded on the optical disk 4 in order.If older personal medical information is needed, it can be searched. is performed on file 7.

As mentioned above, personal medical information is recorded on each optical disk for each individual, and the necessary personal medical information can be searched for on one optical disk. Therefore, the amount of information to be searched is extremely small. , the search time will be very short.

By the way, in the case of a 5.25-inch optical disc, the user area capacity is approximately 300 megabytes, and the image information can be stored at 256 pixels with a resolution of 1024 dots 1 x 1024 dots.
(=2”) for a black and white image with a tone of 1
The image information is approximately 1 megabyte. Therefore, approximately 300 pieces of personal medical information will be stored on one optical disc, and this will be the subject of the search. For this reason, compared to the conventional technology, which files the personal medical information of all patients in a hospital and searches for the desired personal medical information from there,
The search will be performed quickly.

In addition, the owner's personal index information is recorded on the optical disc, and by playing this and displaying the image, it is possible to accurately compare the true owner of the optical disc with the bearer by visual inspection. Therefore, the personal medical information of the patient who is actually being diagnosed can be obtained (incorrectly), and past personal medical information can also be immediately obtained and used as diagnostic materials. It goes without saying that optical discs can be used with any diagnostic equipment.

FIG. 4 is a schematic diagram showing another embodiment of a portable information recording medium for an information management system according to the present invention.

In the embodiment shown in FIG. 1, personal index information is recorded together with personal medical information in the user area, and this information is processed by the host computer 1 (FIG. 2) according to a processing program stored therein. However, in the embodiment shown in FIG.
In addition to personal medical information and personal index information, a processing program for processing these information is also recorded in the user area.

Therefore, in FIG. 2, when the recording medium shown in FIG. 4 is an optical disk, the host computer 1 does not store a processing program for processing personal medical information and personal index information for image display. Then, as shown in FIG. 5, when the optical disc 4 is inserted into the disc drive device 3 (step 101), the disc drive device 3 is initialized (step 102), and after that, the optical disc 4 is inserted into the disc drive device 3 (step 101). A processing program is read from the user area of the computer 1 and stored in the host computer 1 (
Step 108). The subsequent processing is performed as steps 103, 104, etc. in FIG. and process personal medical information.

In this specific example as well, personal medical information older than the personal medical information recorded on the optical disc 4 can be searched from the file 7 of the center system 6. However, for this purpose, since the host computer 1 itself does not have a processing program, it is necessary to read the processing program from the optical disk 4 and store it in the host computer 1. Normally, personal medical information is obtained from the file 7 as necessary during a medical examination, so in this case, the optical 3 4 disk 4 is always inserted into the disk drive device 3.

The information management system shown in FIG. 2 using the embodiment shown in FIG. 4 can obtain the same effects as those using the recording medium shown in FIG. 1 can be made smaller. Further, even if the processing program is stored on the optical disc 4, the recording capacity of personal medical information is not particularly affected.

The information management system described above has been explained as being for one hospital, but as shown in FIG. . . . n may be connected to a single center system 6 so that each hospital processes information in the same format. The test results of patients at each hospital are stored in the file 7 of the center system 6, and are also recorded on the optical disc owned by the patient as personal medical information together with directory information.

Although the present invention has been described in detail above, the present invention is applicable to other institutions other than medical institutions, such as financial institutions, and can also be used as a recording medium, such as magnetic disks and magneto-optical disks other than optical disks. , IC memory, optical card, etc. may also be used. However, the conditions for the recording medium according to the present invention are: (1) It must be of a size and weight that can be carried around by a person (in this case, it must be of a size and weight that can fit into a pocket of clothing worn by a person); The most preferable thickness is
For this purpose, in the case of a 5 6 disk-shaped recording medium, the maximum diameter may be 1Q cm).

(2) Must be non-volatile memory.

(3) When recording image information, it must have a large storage capacity of 3 megabytes or more (as explained earlier, high resolution image information requires approximately 1 megabyte of storage capacity. This image information Assuming that this is medical information, in order to be able to diagnose an individual using this information, a minimum of three images is required to understand changes in the medical condition. The storage capacity of is 3
It should be at least 1 megabyte. On the other hand, personal index information, even if it is image information, only needs to have enough information to identify an individual, and for this reason, it may be about 2 kilobytes using a normal data compression method.

In this way, the amount of personal index information can be almost ignored compared to the amount of medical information, and therefore, the recording capacity of the recording medium only needs to be 3 megabytes or more.

In addition, since three or more images are required as medical information, even if high-resolution index information is used,
The recording capacity of this image information may be at least three times the recording capacity of the index information).

(4) It should be inexpensive.

(5) The storage life of the recorded information must be longer than the minimum mandatory medical information retention period (for example, 7 years in the United States and 15 years in West Germany).

etc.

Furthermore, the method of recording personal medical information and directory information on a recording medium is not limited to those shown in FIGS. 1 and 4.

〔Effect of the invention〕

As explained above, according to the present invention, the information of each individual, which is a huge amount when combined, is distributed and recorded separately for each individual, and it is only necessary to perform a search on this recorded information. Information to be searched 7 8 The amount of information to be searched can be extremely reduced, making it possible to search quickly, and personal index information representing the true owner is also recorded, and by displaying this as an image,
Correspondence with the true owner of the recording medium can be visually confirmed accurately and easily, and therefore desired information can be accurately searched.
