Abstract

A system and method to configure a rule set used in connection with a medical monitoring system for monitoring patients and patient care equipment, especially medication delivery pumps, based on a variety of conditions and parameters associated with monitored biometric information and equipment information and for providing user-defined responses to those conditions and parameters.

Claims

1. A method for implementing a medical system algorithm by an authorized medical caregiver, the steps of the method comprising:

providing a context free grammar to define the medical system algorithm, the grammar

comprising non-terminal parameter symbols and terminal parameter symbols that are configured to be satisfied by a plurality of non-terminal medical system parameters and terminal medical system parameters, respectively, the grammar further comprising non-terminal condition symbols and terminal condition symbols that are configured to be satisfied by a plurality of nonterminal medical system conditions and terminal medical system conditions, respectively, the grammar further comprising a response symbol that is configured to be satisfied by a plurality of medical system responses;

receiving a first parameter selection comprising at least of one of the non-terminal parameters or at least one of the terminal parameters, defined by the grammar;

receiving a respective first medical system condition selection corresponding to the at least one of the non-terminal parameter symbol or terminal parameter symbol for the selected first parameter selection defined by the grammar;

receiving a medical system response selection;

generating the medical system algorithm from the first parameter selection, the first medical system condition selection, and the medical system response selection; and

storing the generated medical system algorithm for later use by an automated medical device.

2. The method of claim 1 wherein the first parameter selection comprises at least one of the non-terminal parameter symbols and at least one of the terminal parameter symbols defined by the grammar.

3. The method of claim 1 wherein the response symbol comprises one of a non-terminal response symbol and a terminal response symbol, wherein the response symbol is configured to be satisfied by non-terminal medical system responses and terminal medical system responses, respectively.

4. The method of claim 1 wherein the step of receiving a medical system response comprises receiving a non-terminal medical system response.

5. The method of claim 1 further comprising the steps of:

receiving a second parameter selection comprising at least of one of the non-terminal parameter symbols or at least one of the terminal parameter symbols defined by the grammar; and

,

receiving a respective second medical system condition selection corresponding to the at least one of the non-terminal parameter symbol or terminal parameter symbol for the selected second parameter selection defined by the grammar.

6. The method of claim 5 wherein the second parameter selection comprises at least one of the non-terminal parameter symbols and at least one of the terminal parameter symbols defined by the grammar.

7. The method of claim 5 wherein the first medical system parameter selection is a first alarm selection and wherein the second medical system parameter selection is a second alarm selection, different than the first alarm selection.

8. The method of claim 7 wherein the first alarm selection is for an alarm related to a medical pump function and wherein the second alarm selection is for an alarm related to a patient monitor function.

9. The method of claim 8 wherein the alarm related to the medical pump function is one of a loss of communication with the medical pump alarm and status of medical pump parameter alarm.

10. The method of claim 8 wherein the alarm related to the patient monitor function is one of a loss of communication with the patient monitor alarm and status of a patient monitor parameter alarm.

11. The method of claim 1 wherein the first medical system parameter selection is a first alarm selection.

12. The method of claim 11 wherein the first alarm selection is one of an alarm related to a medical pump function and wherein the second alarm selection is for an alarm related to a patient monitor function.

13. The method of claim 1 wherein the first medical system parameter is a component of a medical system condition.

14. The method of claim 1 further comprising the step of:

receiving a first Boolean connector selection, wherein the step of generating the medical system algorithm is further generated from the first Boolean connector.

15. The method of claim 14 further comprising the step of:

receiving a second Boolean connector selection, wherein the step of generating the medical system algorithm is further generated from the second Boolean connector.

16. The method of claim 1 wherein the medical system parameters are alternative medical system parameters within the grammar, wherein the alternative medical parameters do not represent a medical state or condition of a patient.

17. The method of claim 1 wherein at least one of the medical system parameters defined by the grammar comprises both terminal and non-terminal components.

18. The method of claim 1 wherein the step of receiving a response selection comprises receiving a plurality of response selections.

19. The method of claim 1 wherein the first medical system parameter selection is received through a first region of a user interface display and wherein the medical system response selection is received through a second region of the user interface display.

20. The method of claim 16 wherein at least one of the alternative medical system parameters defined by the grammar comprises a change in communication state with a medical device.
