Claim 14

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: a fourth secondary color is assigned to second and third primary color findings if each of these findings is, by itself, very specific, though not diagnostic for its associated disease.

The method of claim 13 wherein said fourth secondary color is the same color as said fourth primary color.

Claim 16

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: a fourth secondary color is assigned to a fourth primary color finding if said finding is alone very specific, though not diagnostic for its associated disease.

Claim 17

The method of claim 15 wherein said fourth secondary color is the same color as said fourth primary color.

Claim 18

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: a fifth secondary color is assigned to second, third, and fourth primary color findings if each of these findings is often the only finding present with its associated disease.

Claim 19

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: a sixth secondary color is assigned to a third primary color finding if the finding is consistent with its associated disease but occurs much more frequently with other diseases.

Claim 20

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: more than one secondary color may be assigned to a primary color finding.

Claim 21

The method of claim 6 wherein the secondary color code is applied to the findings of the diseases according to the following rule: red is assigned as a secondary color to a first or fourth primary color finding if the finding should be used with caution in ruling in or ruling out associated disease.

Claim 22

The method of claim 1 further comprising the steps of: entering into said processing means data indicating the presence, absence or undetermined presence or absence of findings displayed in step (b); and displaying on a color display coupled to said processing means, in response to entered data, the names of diseases with which said findings are associated, said diseases assigned to a category wherein each category is formulated according to the likelihood of the disease being present in the patient.

Claim 23

The method of claim 21 wherein said categories are formulated according to the following rules: (i) a disease is assigned to a category of eliminated diseases when associated first color findings are present, or when associated findings with the first color as a secondary color are absent; (ii) a disease is assigned to a category of likely possibilities or diseases which must be assumed to be present until proven otherwise when any of the following are present: (a) all associated fourth color findings are present, (b) any associated finding with the fourth color as a secondary color is present, (c) three or more findings other than first color findings are present and no second color findings are absent, (d) four or more findings are present, and not more than one second color finding is absent, other than second color findings having the first secondary color associated therewith, (e) five or more findings are present, and not more than two second color findings are absent, (f) one or more fifth color findings are present, (g) two or more findings are present for a life or organ threatening emergency; (iii) a disease is assigned to a category of unlikely possibilities when more than two second color findings are absent, other than second color findings having a first secondary color associated therewith; or if two or more findings are absent which have a second secondary color associated therewith. (iv) all other diseases are assigned to a category of other possibilities

Claim 24

The method of claim 21 further comprising the step of: displaying on a color display coupled to said processing means, in response to entered data, at least one color-coded symbol corresponding to at least one finding of a displayed disease that has not been determined to be absent or present.

Claim 25

The method of claim 21 further comprising the step of: displaying on a color display coupled to said processing means, in response to entered data, at least one color-coded symbol corresponding to at least one finding of a displayed disease that has been determined to be absent or present.

Claim 26

An interactive computerized apparatus for presenting medical information for diagnosis and study of disease, comprising processing means for processing data indicative of disease findings, including assigning color codes to the disease findings and categorizing the disease findings according to a set of rules; a database containing data indicative of diseases and findings; input means for entering data indicative of at least one of a disease or a finding to the processing means; and output means for providing a color display of diseases and findings, the findings being color coded and categorized on said display according to the significance of the presence or absence of each finding in ruling in or ruling out the possibility of the disease being present.

Claim 27

An interactive computerized apparatus for presenting medical information for diagnosis and study of disease, comprising processing means for processing data indicative of disease findings, including assigning color codes to the disease findings and categorizing the disease findings according to a set of rules; a database containing data indicative of diseases and findings; input means for entering data indicative of at least one of a disease or a finding to the processing means; and output means for providing a color display of diseases and findings, the findings being color coded and categorized on said display according to the significance of the presence or absence of each finding in ruling in or ruling out the possibility of the disease being present.

Claim 28

The apparatus of claim 25 wherein the displayed diseases are color-coded according to the following rule: a first color is assigned to diseases that are life-threatening or organ-threatening emergencies.

Claim 31

The method of claim 27 wherein said color-coded indicator symbol representing at least one finding of said disease is color coded according to the following rules: (i) a first color indicates findings never present with a given disease; (ii) the second primary color is assigned to findings that are at least almost always present with a given disease; (iii) the third primary color is assigned to findings, other than second primary color findings, which are generally specific for, but not diagnostic for, a given disease: (iv) the fourth primary color is assigned to findings that are diagnostic for a given disease.

Claim 32

The method of claim 27 wherein said first indicator symbol color is red.

Claim 33

The method of claim 27 wherein said second indicator symbol color is white.

Claim 34

The method of claim 27 further comprising the step of displaying on a color display coupled to the processing means, in response to entered data, the color-coded findings of each disease.
