Abstract

A medical diagnosis system includes an input such as a floppy disk drive or a keyboard for inputting data of test items obtained by doctor'"'"'s consultation, physical examination, and/or test. A microprocessor unit (1) compares the input data with evaluation ranges to determine into which evaluation range the input data falls, (2) compares the evaluation range with condition groups each including one or more condition formulae, thereby generating an evaluation result of sickness or disorder, and (3) provides data of sickness or disorder including type, level, causes, and comments if the condition groups are satisfied, thereby preparing a list of evaluation results. In the event different evaluation results are obtained with respect to a sickness or disorder, the most serious evaluation result for such sickness or disorder is added to the list of evaluation results. An output such as a printer, floppy disk drive, or display monitor displays the evaluation results list in a sentence format.

Claims

1. A medical diagnosis system comprising:

(a) an input means for inputting data of test items obtained by doctor'"'"'s consultation, physical examination and/or test;

(b) an evaluation range-determining means for comparing each of said input data with evaluation ranges to determine into which evaluation range each of said input data falls, said evaluation ranges being prepared by classifying possible values of each test item into a predetermined number of groups;

(c) a condition group-determining means for comparing said evaluation range determined from each of said input data with condition groups each comprising one or more condition formulae, thereby generating an evaluation result of sickness or disorder;

(d) an evaluation engine means for providing data of sickness or disorder including type, level, causes, and comments if said condition groups are satisfied, thereby preparing a list of evaluation results, wherein in the event different evaluation results are obtained with respect to a sickness or disorder, the most serious evaluation result with respect to such sickness or disorder is added to said list of evaluation results; and

(e) an output means for displaying said evaluation result list in a sentence format.

2. The medical diagnosis system according to claim 1, wherein said condition group consists of an evaluation range formula of a particular test item combined with other evaluation range formulae of closely related test items in order to evaluate all the sickness or disorder relating to said particular test item.

3. The medical diagnosis system according to claim 1, wherein said evaluation range for each test item is classified into (2n+1) ranges from -n to +n while assigning 0 to a normal state.

4. The medical diagnosis system according to claim 2, wherein said evaluation range for each test item is classified into (2n+1) ranges from -n to +n while assigning 0 to a normal state.

5. The medical diagnosis system according to claim 1, wherein each condition group comprises one or more evaluation range formulae for comparing the evaluation ranges of one or more related test items with predetermined levels, each of said evaluation range formulae being connected by OR or AND.

6. A medical diagnosis system comprising:

(a) an input means for inputting data of test items obtained by doctor'"'"'s consultation, physical examination and/or test;

(b) a first memory means for storing evaluation range data prepared by classifying possible values of each test item into (2n+1) ranges from -n to +n while assigning 0 to a normal state;

(c) an evaluation range-determining means for comparing each of said input data with said evaluation ranges retrieved from said first memory means to determine into which evaluation range each of said input data falls;

(d) a second memory means for storing condition groups, each condition group comprising one or more condition formulae for comparing the evaluation ranges of one or more related test items with predetermined levels;

(e) a condition group-determining means for determining whether said evaluation range determined from each of said input data satisfies the condition formulae in said condition groups retrieved from said second memory means, thereby generating an evaluation result of sickness or disorder from said related test items;

(f) a third memory means for storing data of sickness or disorder including type, level, causes, and comments;

(g) an evaluation engine means for retrieving said data of sickness or disorder from said third memory means if said condition groups are satisfied, thereby preparing a list of evaluation results, wherein in the event different evaluation results are obtained with respect to a sickness or disorder, the most serious evaluation result with respect to such sickness or disorder is added to said list of evaluation results; and

(h) an output means for displaying said evaluation result list in a sentence format.
