Computer system and method for suggesting treatments for physical trauma
First Claim
1. An expert system for providing to a user one or more suggested treatments for a patient with physical trauma, comprising:
- a computing device having a memory;
a plurality of data bases in the memory including graphical illustrations of different types of physical trauma, and a knowledge base having rules for relating trauma and patient characteristics to treatments for said different types of physical trauma;
an application program, for execution in the computing device, for interactively displaying a series of screens including at least some of the graphical illustrations, to thereby elicit responses from the user concerning the specific type of physical trauma and specific characteristics of the patient, to thereby produce a further data base containing said trauma and patient characteristics; and
an inference engine program, for execution in the computing device, for use with said rules and said further data base, for selecting the one or more suggested treatments by stepping through a forward chaining sequence of rules relating to a particular treatment, and then by stepping through a backward chaining sequence of rules, the reverse of the forward chainin sequence, in which said rules are tested, based on said trauma and patient characteristics, to determine the desirability of said particular treatment;
the application program presenting the suggested treatments to the user after execution of the inference program.

Abstract
An expert system which provides one or more suggested treatments for a patient with physical trauma is disclosed. The system includes a computing device having a memory, a plurality of data bases in the memory, an application program and an inference engine program. The data bases include graphical illustrations of different types of physical trauma, and a knowledge base which contains treatment information. The application program is executed in the computing device and interactively displays a series of screens including at least some of the graphical illustrations, to elicit responses from the user concerning the specific types of physical trauma and specific characteristics of the patient. The inference engine program, which is also executed in the computing device, uses the knowledge base and information related to the responses elicited from the user, for selecting one or more suggested treatments. The application program presents the suggested treatments to the user after execution of the inference engine program.

2. An expert system for providing to a user one or more suggested treatments for a patient with an orthopedic fracture, comrising:
-
a computing device having a memory; a plurality of data base in the memory, including graphical illustrations of different classifications of orthopedic fractures; and
a knowledge base having rules for relating trauma and patient characteristics to treatments for said different types of physical trauma;an aplication program, for execution by the computing device, for interatively displaying a series of screens on a display, including at least some of the graphical illustrations, to thereby elicit responses from the user concerning the specific classification of orthopaedic fracture, and specific characteistics of the patient;
to thereby produce a further data base containing said trauma and patient characteristics; andan inference engine program, for execution in the computing device, for use with said rules and said further data base, for selecting the one or more suggested treatments by stepping through a forward chaining sequence of rules relating to a particular treatment, and then by stepping through a backward chaining sequence of rules, the reverse of the forward chaining sequence, in which said rules are tested, based on said trauma and patient characteristics, to determine the desirability of said particular treatment; the application program presenting the suggested treatments to the user after execution of the inference program.

3. A method for providing to a user a suggested treatment for a patient having physical trauma, comprising the steps of:
-
creating at least one knowledge base containing rules that relate different types of physical trauma characteristics and patient characteistics to different types of treatments for physical trauma; eliciting information from said user concerning characteristics of said patient including the type of physical trauma substained by said patient, to thereby develop at least one database containing patient and trauma characteristics; applying said knowledge base and database to a computer; and using said computer to infer the apropriate treatment for said patient from said rules and said database, by forward chaining, in which a sequence of rules relating to a particular treatment is established, and backward chaining, in which said sequence of rules es reversed and said rules are tested based on said trauma and patient characteristics, to determine the desirability of said particular treatment. - View Dependent Claims (4, 5, 6, 7, 8, 9, 10)

11. An expert system for providing to a user a suggested treatment for a patient having physical trauma, comprising:
-
at least one knowledge base containing rules that relate different types of physical trauma characteristics and patient characteristics to different types of treatments for physical trauma, a computer for receiving said knowledge base and information from said user concerning characteristics of said patient, including the type of physical trauma sustained by said patient, to thereby develop at least one database containing patient and trauma characteristics; and an processor within said computer to infer the appropriate treatment for said patient from said rules and said database by forward chaining, in which a sequence of rules relating to a particular treatment is established, an then by backward chaining, in which said sequence of rules is reversed and said rules are tested based on said trauma and patient characteristics, to determine the desirability of said particular treatment. - View Dependent Claims (12, 13, 14, 15, 16, 17)
