Abstract

This document discusses, among other things, a user interface capable of resolving interactions between programmable parameters for operation of a personal medical device. Programming these devices is a difficult task when many parameters are involved. The medical device interface attempts to reduce and minimize constraint violations between interdependent parameters using an initial set of parameter values supplied by user (typically a physician) input, and constraint violations describing invalid parameter values. A user is given the option to select one or more parameters to remain constant. If possible, a set of parameter values with less egregious constraint violations is displayed to the user. A user is prompted to accept the set of parameter values and program the medical device.

Claims

1. A user interface device for a multi-parameter programmable personal medical device having one or more parameter interaction constraints between different programmable parameters, the user interface device comprising:

a first set of user-programmable parameter values that creates one or more first violations of at least one of the constraints; and

an interaction resolution engine, that automatically attempts to determine, from the first set of parameter values, a second set of parameter values that reduces or resolves the one or more first violations while (1) avoiding or reducing a degree of any other violations of the constraints; and

(2) reducing or minimizing an indication of a variation between the first and second sets of parameter values.

2. The user interface device of claim 1, comprising:

a user input device adapted to receive from the user as input one or more of the first set of parameter values; and

an acceptance selector that permits the user to accept the second set of parameter values for programming into the personal medical device.

3. The user interface device of claim 1, comprising one or more stored measurements from the personal programmable medical device, wherein the first set of user-programmable parameter values is determined automatically using the one or more stored measurements.

4. The user interface device of claim 1, comprising a prioritizing selector that permits a user to select at least one parameter to be given a high priority for being held constant in automatically determining the second set of parameter values from the first set of parameter values.

5. The user interface device of claim 1, comprising:

a memory circuit to store one or more candidate second sets of parameter values; and

a weight of change analyzer module that classifies one or more of the candidate second sets of parameter values according using a weight of change with respect to the first set of parameter values.

6. The user interface device of claim 5, wherein the one or more second sets of parameter values vary one or more individual parameters in value in steps from a corresponding value in the first set of parameter values, each of the varying one or more individual parameters including:

a corresponding difference in steps from the corresponding value in the first set of parameter values; and

a total number of steps for the parameter or a total number of candidate values for the parameter.

7. The user interface device of claim 6, wherein each of the varying one or more individual parameters includes a weight of change from the corresponding value in the first set of parameter values, the weight of change determined using the difference in steps and the total number of steps.

8. The user interface device of claim 7, wherein the one or more of the candidate second sets of parameter values includes a corresponding weight of change determined by combining the weights of change of individual parameters in the candidate second set of parameter values.

9. The user interface device of claim 8, wherein the memory circuit is configured to store an array of the one or more candidate second sets of parameter values ordered according to the weight of change associated with each of the one or more candidate second sets of parameter values, and wherein the interaction resolution engine is configured to consider the one or more candidate second sets of parameter values sequentially as ordered.

10. The user interface device of claim 9, comprising:

a parameter constraint violation comparison module to determine whether the second set of parameter values avoids or reduces a degree of violations of the constraints when compared to the first set of parameter values, wherein the parameter constraint violation comparison module deems a reduced degree of violations to exist if at least one of;

the second set of parameter values includes fewer of a first type of constraint violations; and

the first and second set of parameter values include an equal number of the first type of constraint violations, but the second set of parameter values includes fewer of a second type of constraint violations.

11. The user interface device of claim 10, wherein the interaction resolution engine includes at least one exit condition to terminate the automatic attempt to determine the second set of parameter values, the exit condition comprising at least one of:

a second set of parameter values has been found with no associated constraint violations;

a defined maximum number of iterations is reached; and

all candidate second sets of parameter values have been exhausted.

12. A method comprising:

obtaining a first set of parameter values governed by one or more parameter interaction constraints;

determining whether the first set of parameter values creates one or more first violations of at least one parameter interaction constraint; and

automatically determining, from the first set of parameter values, a second set of parameter values that reduces or resolves the one or more first violations while (1) avoiding or reducing the degree of any other violations of the constraints;

and (2) reducing or minimizing an indication of a variation between the first and second sets of parameter values.

13. The method of claim 12, wherein the obtaining the first set of parameter values includes obtaining from a user at least one value in the first set of parameter values.

17. The method of claim 12, comprising:

communicating the automatically determined second set of parameter values to a user;

20. The method of claim 19, comprising:

initializing a current set of parameter values to the first set of parameter values; and

comparing, until an exit condition occurs, candidate second sets of parameter values to the current set of parameter values and, if a candidate second set of parameter values contains less severe constraint violations than the current set of parameter values, then replacing the current set of parameter values with the second set of parameter values that contains less severe constraint violations than the current set of parameter values.
