The communication network 420 may be either wired or wireless. The medical staff may be, for example, a doctor.

[0014] As shown in Figure 2, the present device 100 has a disease name candidate storage means 110, a first basis storage means 120, a second basis storage means 130, a past information storage means 140, a patient input acceptance means 150, a disease name candidate determination means 160, a past information necessity determination means 170, a past information extraction means 180, an additional information necessity determination means 190, an additional hearing means 200, and a medical examination information provision means 210.

[0015] The disease name candidate storage means 110 stores the medical needs 400 of the patient 380 in association with the disease name candidates 310. The medical needs 400 may be symptoms that the patient 380 complains about, or may be content such as "I have symptoms of XX and would like to be examined" or "I would like medicine."

[0016] 3 is a diagram showing an example of the disease name candidate storage means 110. As shown in FIG. 3, the disease name candidate storage means 110 stores, for example, a medical request 400: "I have a fever, so I'd like to be examined" and a disease name candidate 310: "upper respiratory tract infection" in association with each other. Also, the disease name candidate storage means 110 stores, for example, a medical request 400: "I want medicine" and a disease name candidate 310: "hay fever" in association with each other.

[0017] The first basis storage means 120 stores disease name candidates 310, necessity 340 of past medical information 320, and item identification information 330 related to the past information 320 in association with each other. The past information 320 is information including one or more of the following: medical history, test results, medication history, allergy history, family history, career / work history, life history / lifestyle, health checkup results, and past medical examination information. The item identification information 330 is information for identifying the following items: medical history, test results, medication history, allergy history, family history, career / work history, life history / lifestyle, health checkup results, and past medical examination information.

[0018] 4 is a diagram showing an example of the first basis storage means 120. As shown in FIG. 4, the first basis storage means 120 stores, in association with each other, a disease name candidate 310 (upper respiratory tract inflammation) and a necessity / non-necessity of past information 340 (not required). The first basis storage means 120 also stores, in association with each other, a disease name candidate 310 (suspected dyslipidemia) and a necessity / non-necessity of past information 340 (necessary), and item identification information 330 (test results).

[0019] The second basis storage means 130 stores the disease name candidate 310, the necessity 350 of additional medical information 360, and the required hearing information 360 that should be additionally obtained from the patient 380 in association with each other.

[0020] 5 is a diagram showing an example of the second basis storage means 130. As shown in Fig. 5, the second basis storage means 130 stores, in association with each other, a disease name candidate 310 (e.g., upper respiratory tract inflammation) and additional information necessity 350 (e.g., not required). The second basis storage means 130 also stores, in association with each other, a disease name candidate 310 (e.g., migraine) and additional information necessity 350 (e.g., required), and hearing information 360 (e.g., headache onset time, duration, accompanying symptoms, etc.).

[0021] The past information storage means 140 stores patient identification information 390, item identification information 330 related to the past information 320, and past information 320 related to the item identified by the item identification information 330, in association with each other. In the past information storage means 140, past information 320 is stored for each patient identification information 390 and each item identification information 330.

[0022] The patient input receiving means 150 receives a disease name candidate 310 claimed by a patient 380 identified by the patient identification information 390. The patient input receiving means 150 may also be configured to receive a medical request 400 claimed by the patient 380 identified by the patient identification information 390. The medical request 400 may be a symptom complained by the patient 380, or may be a request for a medical examination because of symptoms such as "I have XX symptoms" or "I want medicine."

[0023] The disease name candidate determination means 160 extracts disease name candidates 310 stored in association with medical needs 400 asserted by a patient 380 from the information stored in the disease name candidate storage means 110 .

[0024] 3, for example, when the medical need 400 is "abnormal test result (TG)," the disease name candidate determination means 160 extracts a disease name candidate 310 such as suspected dyslipidemia that is stored in association with the medical need 400: abnormal test result (TG) from the information stored in the disease name candidate storage means 110. Also, for example, when the medical need 400 is "I want medicine," the disease name candidate determination means 160 extracts a disease name candidate 310 such as hay fever that is stored in association with the medical need 400: I want medicine from the information stored in the disease name candidate storage means 110.

[0025] The past information necessity determination means 170 refers to the information stored in the first basis storage means 120 to identify and determine whether past information is necessary 340 associated with the disease name candidate 310 accepted by the patient input acceptance means 150 or the disease name candidate 310 extracted by the disease name candidate determination means 160. When the past information necessity determination means 170 determines that the past information necessity 340 is "necessary," it identifies, from the information stored in the first basis storage means 120, the item identification information 330 stored in association with the disease name candidate 310 that is the basis for the determination.

[0026] The processing by the past information necessity determination means 170 identifies the past information 320 necessary for the examination of the patient 380, so from the patient's perspective, it is possible to save the effort of explaining the past related to the examination and to compensate for any lack of explanation ability. On the other hand, from the doctor's perspective, it is possible to smoothly obtain only the information necessary for the examination and also to reduce the risk of misdiagnosis due to insufficient information.

[0027] As shown in Figure 4, for example, when the disease name candidate 310 is "migraine," the past information necessity determination means 170 determines whether the past information stored in the first basis storage means 120 in association with the disease name candidate 310: migraine is necessary 340: unnecessary, and determines that the past information 320 is "unnecessary."

[0028] Furthermore, for example, when the disease name candidate 310 is "high blood pressure," the past information necessity determination means 170 specifies whether past information necessity 340 stored in the first basis storage means 120 in association with the disease name candidate 310: high blood pressure is necessary, and determines that the past information 320 is "necessary." Then, from the information stored in the first basis storage means 120, the past information necessity determination means 170 specifies, as the necessary past information 320, the item identification information 330: vital signs test, etc., stored in association with the disease name candidate 310: high blood pressure, which is the basis for the determination.

[0029] The past information extraction means 180 extracts from the past information storage means 140 past information 320 stored in correspondence with the patient identification information 390 of the patient 380 who is the target of the patient input acceptance means 150 and the item identification information 330 identified by the past information necessity determination means 170.

[0030] The additional information necessity determination means 190 refers to the information stored in the second basis storage means 130 and identifies and determines whether additional information is necessary 350 associated with the disease name candidate 310 accepted by the patient input acceptance means 150 or the disease name candidate 310 extracted by the disease name candidate determination means 160. When the additional information necessity determination means 190 determines that the additional information necessity 350 is "necessary," it identifies, from the information stored in the second basis storage means 130, the hearing requirement information 360 stored in association with the disease name candidate 310 that is the basis for the determination.

[0031] The processing by the additional information necessity determination means 190 identifies the required hearing information 360 necessary for the examination of the patient 380, so that from the patient's perspective, any lack of explanation ability related to the examination is compensated for. On the other hand, from the doctor's perspective, the information necessary for the examination can be identified and acquired in advance, and the risk of misdiagnosis due to insufficient information is also reduced.

[0032] As shown in Figure 5, for example, when the disease name candidate 310 is "rhinitis," the additional information necessity determination means 190 determines whether additional information is necessary 350 (not necessary) stored in the second basis storage means 130 in association with the disease name candidate 310 (rhinitis), and determines that additional medical information is "not necessary."

[0033] Furthermore, for example, when the disease name candidate 310 is "migraine," the additional information necessity determination means 190 determines whether additional information is necessary 350 (necessary) stored in association with the disease name candidate 310 (migraine) in the second basis storage means 130, and determines that additional medical information (interview required information 360) is "necessary."The additional information necessity determination means 190 then determines, from the information stored in the second basis storage means 130, the interview required information 360 (time of headache onset, duration, accompanying symptoms, etc.) stored in association with the disease name candidate 310 (migraine) that is the basis for the determination.

[0034] The additional hearing means 200 presents the hearing required information 360 identified by the additional information necessity determination means 190 to the patient 380 (or to a terminal operated by the patient) who is the target of the patient input receiving means 150, and requests a response 370 regarding the hearing required information 360.

[0035] The examination information providing means 210 provides the past information 320 extracted by the past information extracting means 180 and / or the answer 370 regarding the hearing-required information 360 requested by the additional hearing means 200 to the examination terminal 410 of the patient 380 who is the target of the patient input accepting means 150. The past information 320 and / or the answer 370 regarding the hearing-required information 360 provided to the examination terminal 410 are used by the doctor in examining the patient 380.

[0036] Based on the above-described operating principle, the device 100 allows patients to save the trouble of having to explain past medical examinations and compensate for any lack of explanation ability, while allowing medical providers to smoothly obtain the information necessary for medical examinations and reduce the risk of misdiagnosis due to insufficient information.

(Examples of Processing by the Diagnosis Support Device According to the Present Embodiment) (1) Example of Processing by the Present Device 100 (Part 1)

[0043] The flow of a processing example (part 1) performed by the present device 100 will be described using Fig. 7. Fig. 7 is a flowchart showing the flow of a processing example (part 1) performed by the present device 100. In S10, the patient input accepting means 150 accepts a disease name candidate 310 claimed by a patient 380 identified by patient identification information 390.

[0044] In S20, the past information necessity determination means 170 refers to the information stored in the first basis storage means 120 to identify and determine whether past information 340 associated with the disease name candidate 310 received in S10 is necessary.

[0045] If the past information necessity determination means 170 determines in S30 that the past information necessity 340 is "necessary" in S20, it identifies the item identification information 330 stored in association with the disease name candidate 310 that is the basis for the determination from the information stored in the first basis storage means 120.

[0046] As shown in Figure 4, for example, when the disease name candidate 310 is "migraine," the past information necessity determination means 170 determines whether the past information stored in the first basis storage means 120 in association with the disease name candidate 310: migraine is necessary 340: unnecessary, and determines that the past information 320 is "unnecessary."

[0047] Furthermore, for example, when the disease name candidate 310 is "high blood pressure," the past information necessity determination means 170 specifies whether past information necessity 340 stored in the first basis storage means 120 in association with the disease name candidate 310: high blood pressure is necessary, and determines that the past information 320 is "necessary." Then, from the information stored in the first basis storage means 120, the past information necessity determination means 170 specifies, as the necessary past information 320, the item identification information 330: vital signs test, etc., stored in association with the disease name candidate 310: high blood pressure, which is the basis for the determination.

[0048] The processing in S20 and S30 identifies the past information 320 necessary for examining the patient 380, so that the patient 380 can save the trouble of explaining the past related to the examination and compensate for any lack of explanation ability. On the other hand, from the doctor's perspective, only the information necessary for the examination can be smoothly obtained and the risk of misdiagnosis due to lack of information is also reduced.

[0049] In S40, the past information extraction means 180 extracts from the past information storage means 140 the past information 320 stored in association with the patient identification information 390 of the patient 380 to be processed in S10 and the item identification information 330 specified in S30.

[0050] In S50, the examination information providing means 210 provides the past information 320 extracted in S40 to the examination terminal 410 of the patient 380 who is the processing target in S10. The past information 320 provided to the examination terminal 410 is used when the doctor examines the patient 380.

[0051] By performing the above-described processing, the device 100 can save the patient the trouble of having to explain the past medical examinations and compensate for any lack of explanation ability, and the medical provider can smoothly obtain the information necessary for the examination and reduce the risk of misdiagnosis due to lack of information. (2) Processing Example (Part 2) by the Device 100

[0052] The flow of a second example of processing by the device 100 will be described with reference to Fig. 8. Fig. 8 is a flowchart showing the flow of a second example of processing by the device 100. In S110, the patient input accepting means 150 accepts a disease name candidate 310 claimed by a patient 380 identified by patient identification information 390.

[0053] In S120, the additional information necessity determination means 190 refers to the information stored in the second basis storage means 130 to identify and determine whether additional information 350 associated with the disease name candidate 310 received in S110 is necessary.

[0054] If the additional information necessity determination means 190 determines in S130 that the additional information necessity 350 is "necessary" in S120, it identifies the hearing requirement information 360 stored in association with the disease name candidate 310 that is the basis for the determination from the information stored in the second basis storage means 130.

[0055] As shown in Figure 5, for example, when the disease name candidate 310 is "rhinitis," the additional information necessity determination means 190 determines whether additional information is necessary 350 (not necessary) stored in the second basis storage means 130 in association with the disease name candidate 310 (rhinitis), and determines that additional medical information is "not necessary."

[0056] Furthermore, for example, when the disease name candidate 310 is "migraine," the additional information necessity determination means 190 determines whether additional information is necessary 350 (necessary) stored in association with the disease name candidate 310 (migraine) in the second basis storage means 130, and determines that additional medical information (interview required information 360) is "necessary."The additional information necessity determination means 190 then determines, from the information stored in the second basis storage means 130, the interview required information 360 (time of headache onset, duration, accompanying symptoms, etc.) stored in association with the disease name candidate 310 (migraine) that is the basis for the determination.

[0057] The processing by the additional information necessity determination means 190 identifies the required hearing information 360 necessary for the examination of the patient 380, so that from the patient's perspective, any lack of explanation ability related to the examination is compensated for. On the other hand, from the doctor's perspective, the information necessary for the examination can be identified and acquired in advance, and the risk of misdiagnosis due to insufficient information is also reduced.

[0058] In S140, the additional hearing means 200 presents the hearing required information 360 identified in S130 to the patient 380 (or to a terminal operated by the patient 380) who is the processing target in S110, and requests a response 370 regarding the hearing required information 360. After this processing, the device 100 acquires the response 370 regarding the hearing required information 360 from the patient 380.

[0059] In S150, the examination information providing means 210 provides a response 370 regarding the hearing required information 360 requested from the patient 380 in S140 to the examination terminal 410 of the patient 380 to be processed in S110. The response 370 regarding the hearing required information 360 provided to the examination terminal 410 is used in the doctor's examination of the patient 380.

[0060] By performing the above-described processing, the device 100 can save the patient the trouble of having to explain the past medical examinations and compensate for any lack of explanation ability, and the medical provider can smoothly obtain the information necessary for the examination and reduce the risk of misdiagnosis due to lack of information. (3) Processing Example (Part 3) by the Device 100

[0062] In S210, the patient input receiving means 150 receives a medical request 400 asserted by the patient 380 identified by the patient identification information 390. The medical request 400 may be a symptom complained of by the patient 380, or may be a request for a medical examination because of a certain symptom, or a request for medicine, etc.

[0063] In S220, the disease name candidate determination means 160 extracts the disease name candidate 310 stored in association with the medical need 400 received in S210 from the information stored in the disease name candidate storage means 110.

[0064] 3, for example, when the medical need 400 is "abnormal test result (TG)," the disease name candidate determination means 160 extracts a disease name candidate 310 such as suspected dyslipidemia that is stored in association with the medical need 400: abnormal test result (TG) from the information stored in the disease name candidate storage means 110. Also, for example, when the medical need 400 is "I want medicine," the disease name candidate determination means 160 extracts a disease name candidate 310 such as hay fever that is stored in association with the medical need 400: I want medicine from the information stored in the disease name candidate storage means 110.

[0065] Thereafter, in the processes of S20 to S50 and S120 to S150, the device 100 performs the processes using the "disease name candidate 310 extracted in S220" instead of the "disease name candidate 310 accepted in S10".

[0066] By performing the above-described processing, the device 100 can save the patient the trouble of having to go through previous explanations related to the examination and compensate for any lack of explanation ability, and on the medical provider side, it can smoothly obtain the information necessary for the examination and reduce the risk of misdiagnosis due to lack of information.
