Abstract

A medical pump that provides advance guidance to a user regarding existence and limits of a valid input range for a pump programming parameter includes an input device for entering a value of a pump programming parameter, a memory for storing constraints related to the pump programming parameter, and a processor in communication with the memory and the input device. The processor dynamically utilizes the constraints to determine and generate a signal indicating whether a valid input range exists for a to-be-entered value of the pump programming parameter and notifies the user.

Claims

1. A medical pump system that provides advance guidance to a user regarding existence and non-existence of a valid input range for a pump programming parameter, comprising:

an input device for entering a value of a pump programming parameter;

a memory for storing constraints related to the pump programming parameter;

a processor in communication with the memory and the input device, the processor being operable to utilize the constraints to determine and generate a signal, determined from among an affirmative signal and a negative signal, indicating whether a valid input range exists for a to-be-entered value of the pump programming parameter; and

an output device in communication with the processor to receive the signal indicating whether a valid input range exists for a to-be-entered value of the pump programming parameter and, for both a determination that the signal is the affirmative signal and a determination that the signal is the negative signal, explicitly generate a notification to a user of the medical pump system based on the signal immediately prior to attempted input of the to-be-entered value of the pump programming parameter.

2. The medical pump system of claim 1, wherein the notification indicates to the user that a valid input range for the to-be-entered value is absent.

3. The medical pump system of claim 1, wherein the notification indicates to the user that a valid input range for the to-be-entered value is present.

4. The medical pump system of claim 3, wherein the notification comprises a message identifying an upper limit and a lower limit of the valid input range based upon the signal.

5. The medical pump system of claim 4, wherein the output device is a display screen and the message is generated on the display screen.

6. The medical pump system of claim 1, wherein one of the constraints is derived from a medical device capability predetermined by a manufacturer of the medical pump system.

7. The medical pump system of claim 1, wherein at least one of the constraints is derived from a drug library.

8. The medical pump system of claim 1, wherein the constraints comprise multiple sets of constraints and a smallest maximum constraint among the constraints and a largest minimum constraint among the constraints are used to determine whether a valid range exists and to define the valid range.

9. The medical pump system of claim 1, wherein one of the constraints comprises a predetermined equation that relates the to-be-entered pump programming parameter to a plurality of other pump programming parameters.

10. The medical pump system of claim 9, wherein the predetermined equation is back calculated or solved for the maximum and minimum values of the to-be-entered pump programming parameter based upon a maximum and a minimum of one of the other pump programming parameters.

11. The medical pump system of claim 9, wherein at least one of the plurality of other pump programming parameters has already been entered.

12. The medical pump system of claim 11, wherein the to-be-entered pump programming parameter is rate and among the plurality of previously entered pump programming parameters is one of time and volume to be infused.

13. The system of claim 12 wherein the maximum and minimum values of the to-be-entered pump programming parameter are rounded during calculation.

14. The system of claim 12 wherein the maximum value of the to-be-entered pump programming parameter is truncated during calculation.

15. The system of claim 12 wherein the minimum value of the to-be-entered pump programming parameter is ceiled during calculation.

16. The system of claim 12 wherein when calculated at least one of the maximum and minimum values of the to-be-entered pump programming parameter is compared to a medical device capability constraint.

17. The system of claim 16 wherein the valid range is adjusted after comparison to the medical device capability constraint to create an adjusted valid range.

18. The medical pump system of claim 10, wherein the back calculation of the valid range is dynamically back calculated anytime a related pump programming parameter is altered.

19. The medical pump system of claim 10, wherein the to-be-entered pump programming parameter is recalculated using a second predetermined equation.

20. The medical pump system of claim 5, wherein the message is displayed on the display screen concurrently with an input field for receiving input of the to-be-entered value of the pump programming parameter.

21. A medical pump system that provides advance guidance to a user regarding unavailability of a valid input range for a pump programming parameter, comprising:

an input device for entering a value of a pump programming parameter;

a memory for storing constraints related to the pump programming parameter;

a processor in communication with the memory and the input device, the processor being operable to utilize the constraints to determine and generate a signal indicating unavailability of a valid input range for a to-be-entered value of the pump programming parameter; and

an output device in communication with the processor to receive the signal indicating the unavailability of a valid input range for a to-be-entered value of the pump programming parameter and generate a notification of the unavailability of a valid input range to a user of the medical pump system based on the signal prior to attempted input of the to-be-entered value of the pump programming parameter.
