Abstract

Claims (36)

1. An infusion pump configured to provide one or more context cues to a user while the user programs the infusion pump to deliver an infusion therapy, the infusion pump comprising:

a processor; and

a memory in communication with the processor and configured to store instructions that when executed by the processor cause the execution of a keypad sequence monitor configured to:

receive one or more context parameters, the context parameters corresponding to a drug selection, a drug concentration selection, or a clinical care area in which a fluid is to be infused;

determine lower and upper soft limit values and lower and upper hard limit values corresponding to the context parameters, wherein a valid treatment parameter range associated with a treatment parameter corresponds to a range of values between the lower and upper soft limit values;

receive a user input;

update a sequence value based upon the user input;

determine that the sequence value is outside of the valid treatment parameter range;

determine that an updated context parameter different from the received context parameters is associated with updated lower and upper soft limit values that define an updated valid treatment parameter range for the treatment parameter that includes the sequence value; and

provide for display one or more context cues corresponding to the updated context parameter.

2. The infusion pump of claim 1 , wherein the keypad sequence monitor is further configured to receive the one or more context parameters from the user via a keypad.

3. The infusion pump of claim 1 , wherein the keypad sequence monitor is further configured to receive the one or more context parameters over a network.

4. The infusion pump of claim 1 , wherein a drug library comprises the lower and upper soft and hard limit values.

5. The infusion pump of claim 1 , wherein a drug library comprises lower and upper soft and hard limit values for each combination of context parameters.

6. The infusion pump of claim 1 , wherein the user input comprises a numerical value associated with the treatment parameter, and wherein the treatment parameter comprises one of a dose, an infusion rate, a volume to be infused, an infusion duration, or a patient weight.

7. The infusion pump of claim 1 , wherein the keypad sequence monitor is further configured to determine that the sequence value is outside of the valid treatment parameter range prior to receiving a user input that indicates that the user wishes to store and execute the infusion pump program.

8. The infusion pump of claim 7 , wherein the user input that indicates that the user wishes to store and execute the infusion pump program comprises an ENTER or RETURN keypress.

9. The infusion pump of claim 1 , wherein the keypad sequence monitor is further configured to display the one or more context cues by altering the appearance of the displayed context parameter that corresponds to the updated context parameter.

10. The infusion pump of claim 1 , wherein the keypad sequence monitor is further configured to update a keypad indicator in response to the received user input, wherein the keypad indicator indicates which subsequent user input would cause the sequence value to change and to become within the valid treatment parameter range.

11. A method of providing one or more context cues to a user while the user programs an infusion pump to deliver an infusion therapy, the method comprising:

receiving one or more context parameters, the context parameters corresponding to a drug selection, a drug concentration selection, or a clinical care area in which the drug is to be infused;

determining lower and upper soft limit values and lower and upper hard limit values corresponding to the context parameters, wherein a valid treatment parameter range associated with a treatment parameter corresponds to a range of values between the lower and upper soft limit values;

receiving a user input;

updating a sequence value based upon the user input;

determining that the sequence value is outside of the valid treatment parameter range;

determining that an updated context parameter different from the received context parameters is associated with updated lower and upper soft limit values that define an updated valid treatment parameter range for the treatment parameter that includes the sequence value; and

displaying one or more context cues corresponding to the updated context parameter.

12. The method of claim 11 , wherein receiving the one or more context parameters comprises receiving the one or more context parameters from the user via a keypad.

13. The method of claim 11 , wherein receiving the one or more context parameters comprises receiving the one or more context parameters over a network.

14. The method of claim 11 , wherein a drug library comprises the lower and upper soft and hard limit values.

15. The method of claim 11 , wherein a drug library comprises lower and upper soft and hard limit values for each combination of context parameters.

16. The method of claim 11 , wherein the user input comprises a numerical value associated with the treatment parameter, and wherein the treatment parameter comprises one of a dose, an infusion rate, a volume to be infused, an infusion duration, or a patient weight.

17. The method of claim 11 , further comprising determining that the sequence value is outside of the valid treatment parameter range prior to receiving a user input that indicates that the user wishes to store and execute the infusion pump program.

18. The method of claim 17 , wherein the user input that indicates that the user wishes to store and execute the infusion pump program comprises an ENTER or RETURN keypress.

19. The method of claim 11 , wherein displaying the one or more context cues comprises altering the appearance of the displayed context parameter that corresponds to the updated context parameter.

20. The method of claim 11 , further comprising updating a keypad indicator in response to the received user input, wherein the keypad indicator indicates which subsequent user input would cause the sequence value to change and to become within the valid treatment parameter range.
