Embodiment Construction

[0027] The content of the present invention will be explained below in conjunction with the accompanying drawings.

[0028] In this technical scheme, the disease database and symptom database are constructed first. The disease database and the symptom database are collections of disease and symptom entries respectively, and the association between them is established and related description information is included. There is a many-to-many relationship between symptoms and diseases. Each symptom corresponds to multiple diseases, and each disease corresponds to multiple symptoms. Different combinations of symptoms may be caused by different diseases; each disease will show one or several symptoms , see attached figure 1 .

[0029] Symptoms are the main feature of a suspected disease. In this technical solution, the patient is modeled according to the symptom information of each patient. Modeling is to record and organize the symptom information input by the patient, and use i...

Abstract

The invention provides a deviation symptom description-oriented automatic computer-aided diagnosis method, belonging to the field of information analysis and aid decision making. The deviation symptom description-oriented automatic computer-aided diagnosis method comprises the steps of: firstly, establishing a disease library and a symptom library and an incidence relation between the disease library and the symptom library, establishing a patient model by using symptoms input by a user, carrying out similarity calculation with the disease model, reasoning and sequencing suspected diseases. The invention has the advantages that the accuracy of a fault interference result is reduced under the condition of using the symptoms mistaken by the user; and according to the fault symptom condition, by combining with the incidence relation among the conventional symptoms, the right symptoms participate in reasoning and operating, and thus reasoning correctness and anti-interference are realized. The invention can be used in an electronic triage or health counseling system, and also used in medical training or clinical reference.

Description

technical field [0001] The invention relates to an auxiliary diagnosis method, which belongs to the field of information analysis and auxiliary decision-making and can be used in a triage system. Background technique [0002] Five major crises in modern medical diagnosis: (1) The continuous increase of medical expenses exceeds the capacity of individuals and society; (2) The explosive growth and confusion of knowledge, young doctors cannot quickly master it, even experienced doctors It is difficult to master the knowledge of diagnosis and treatment across departments; (3) The geographical distribution of medical experts is uneven, and most areas lack high-level doctors; (4) The increasing number of people who need high-level medical services has a strong conflict with the high-quality services that may be provided. (5) Despite the continuous use of high-tech diagnostic techniques, the rate of misdiagnosis and mistreatment remains high. Solving the five major crises in moder...
