[0002]

2. Description of the Related Art Appropriate medical treatment includes symptom of a patient to be treated, results of each test such as specimen, bacteria, pathology, physiology, blood transfusion, radiation, and blood, bacteria, tissue, cell, physiology, etc. It is indispensable to have the latest medical information at the time of performing various medical treatments such as images, medications, surgery and other treatments performed for the disease. At the same time, from the birth to the present, the disease, past illness, allergies, these diseases, past illnesses, existing medications, surgery, other treatments, etc., which the patient suffered from, have been performed. It is also necessary to provide time-series medical information such as the results of various tests performed when the treatment is performed.

[0003]

However, there are various diseases that one patient suffers in his / her life, and one patient may have a medical examination such as a hospital or clinic where he / she has been examined and treated. The number is large and the medical treatment subjects are also diverse. Also, due to social movements such as relocation, medical institutions where one patient has undergone examinations and treatments are scattered over a wide geographical area. It is not uncommon for one patient to undergo medical examinations and treatments throughout his life spanning the entire country. Therefore, it is impossible or extremely difficult for a medical institution that intends to provide medical treatment for a new patient to obtain time-series medical information about the new patient. After all, a medical institution trying to provide medical treatment for a new patient receives medical information about the new patient from the medical institution that introduced the new patient, or performs medical treatment for the new patient each time, There is no choice but to ask a new patient about his medical history and perform an examination.

However, unless medical records such as medical records are disclosed, there is no medical information in the patient's hand, and even if the patient's medical history or medical history is recorded, the patient may correctly memorize them. It is rare. Also, the medical information provided by the referral source medical institution is limited to the medical information accumulated in the medical institution. In the end, it is unavoidable that the same test as the test performed in the past is repeated, and the time until the test result is known must be waited for.
In particular, when a sudden and serious illness is delivered to a medical institution, etc., the medical institution that has been delivered does not have medical information about the patient, and the patient cannot explain the medical history or medical history. In this case, the treatment waiting for the test result is too late, and the treatment performed in the situation where there is no medical information increases the risk of inappropriate medical treatment. On the other hand, it is necessary to surely prevent leakage of medical information of patients obtained from other medical institutions, but in recent computer networks, crimes of invading a specific computer from the outside through a communication line are widespread. .

The problem to be solved by the present invention is as follows.
Using a small-capacity computer, it is possible to quickly, accurately and easily obtain medical information distributed in a large number of medical institutions in a wide geographical range as electronic information, and to prevent natural disasters, power outages, It is to provide a computer system for medical information retrieval that minimizes security risks such as hardware damage due to computer viruses, functional stoppage or loss of information, and intrusion of third parties from the outside. .
