Abstract

A controller for a programmable medical pump comprises a memory including a plurality of preloaded infusion therapies, each preloaded infusion therapy including a plurality of program parameters. The controller also includes a device receiving a selection of one of the preloaded infusion therapies, profile data corresponding to a specific patient, and values for the program parameters. The controller further includes a processor configured to determine which of the plurality of program parameters to associate with the selected preloaded infusion therapy, determine limits for the associated program parameters based upon the selected preloaded infusion therapy and the profile data, determine if the received values of program parameters exceed the determined limits, and responsive to determining that the values of the program parameters are within the determined limits, cause the selected preloaded infusion therapy to be administered via the medical pump using the received values for the program parameters.

First claim

The invention is claimed as follows:

1. A controller for a programmable medical pump comprising:
a memory including a plurality of preloaded infusion therapies, each preloaded infusion therapy including an infusion time program parameter and an infusion dose program parameter that specify how the medical pump is operated to provide a selected preloaded infusion therapy, the infusion time program parameter including a pre-established time limit and the infusion dose program parameter including a pre-established dosage limit;
a device receiving
a selection of one of the plurality of preloaded infusion therapies, and
values for the program parameters of the selected preloaded infusion therapy including a numerical time value for the infusion time program parameter and a numerical dosage value for the infusion dose program parameter; and

a processor configured to
determine that the pre-established dosage limit for the infusion dose program parameter needs to be adjusted based on the numerical time value for the infusion time program parameter to form an adjusted dosage limit,
replace the pre-established dosage limit for the infusion dose program parameter with the adjusted dosage limit,
determine if the received numerical dosage value exceeds the adjusted dosage limit, and
responsive to determining that the received numerical dosage value is within the adjusted dosage limit, cause the selected preloaded infusion therapy to be administered via the medical pump using the received values for the program parameters.

2. The controller of claim 1 , wherein the processor is further configured to provide a notification if it is determined that the received numerical dosage value has exceeded the adjusted dosage limit.

3. The controller of claim 2 , wherein the notification includes a soft alarm that enables the selected preloaded infusion therapy to be administered using the received numerical dosage value that exceeded the adjusted dosage limit.

4. The controller of claim 3 , wherein the selected preloaded infusion therapy is administered using the received numerical dosage value that exceeded the adjusted dosage limit upon an authorization, and wherein the authorization can include at least one of a username and a password.

5. The controller of claim 2 , wherein the notification includes a hard alarm that prevents the selected preloaded infusion therapy from being administered using the received numerical dosage value that exceeded the adjusted dosage limit.

6. The controller of claim 5 , wherein the hard alarm is provided when the received numerical dosage value exceeds a first threshold, while a soft alarm is provided when the received numerical dosage value exceeds a second threshold, the second threshold being closer to the adjusted dosage limit than the first threshold.

7. The controller of claim 1 , wherein each of the plurality of preloaded infusion therapies is at least one of a fluid bolus infusion therapy, a drug bolus infusion therapy, and a loading dose infusion therapy.

8. A method for operating a medical pump comprising:
receiving, at a processor, a selection of a preloaded infusion therapy from among a plurality of preloaded infusion therapies stored in a memory of the medical pump, each preloaded infusion therapy including an infusion time program parameter and an infusion dose program parameter that specify how the medical pump is operated to provide a selected preloaded infusion therapy, the infusion time program parameter including a pre-established time limit and the infusion dose program parameter including a pre-established dosage limit;
receiving, in the processor, profile data corresponding to a specific patient;
providing, via the processor, preset values for the program parameters based upon the selected preloaded infusion therapy and the profile data, the preset values including a numerical time value for the infusion time program parameter and a numerical dosage value for the infusion dose program parameter;
determining, via the processor, that the pre-established dosage limit for the infusion dose program parameter needs to be adjusted based on the numerical time value for the infusion time program parameter to form an adjusted dosage limit,
replacing, via the processor, the pre-established dosage limit with the adjusted dosage limit;
determining, via the processor, if the adjusted dosage limit is exceeded by the numerical dosage value; and
responsive to determining that the numerical dosage value is within the adjusted dosage limit, administering the selected preloaded infusion therapy via the medical pump using the numerical values for the infusion time program parameter and the infusion dose program parameter associated with the selected preloaded infusion therapy.

9. The method of claim 8 , further comprising:
receiving an amended numerical dosage value;
determining if the amended numerical dosage value exceeds the adjusted dosage limit; and
responsive to determining that the amended numerical dosage value is within the adjusted dosage limit, administering the selected preloaded infusion therapy using the amended numerical dosage value.

10. The method of claim 8 , wherein the received profile data includes patient profile data and condition profile data, and wherein the selected preloaded infusion therapy includes a preloaded patient profile and a preloaded condition profile.

11. The method of claim 10 , wherein the selection of the preloaded infusion therapy includes:
selecting the preloaded patient profile associated with the selected preloaded infusion therapy from a plurality of possible preloaded patient profiles, the selected preloaded patient profile most closely matching the received patient profile data;
selecting the preloaded condition profile associated with the selected preloaded infusion therapy from a plurality of possible preloaded condition profiles, the selected preloaded condition profile most closely matching the received condition profile data; and
selecting the preloaded infusion therapy to be the one that includes the most closely matching preloaded patient profile and the most closely matching condition profile.

12. The method of claim 8 , further comprising:
determining that the selected preloaded infusion therapy is to be administered on a first channel of the medical pump;
receiving a selection of a second preloaded infusion therapy from among the plurality of preloaded infusion therapies stored in the memory;
determining that the second selected preloaded infusion therapy is to be administered on a second channel of the medical pump;
receiving second profile data for the second selected preloaded infusion therapy corresponding to the specific patient;
determining a second pre-established time limit for the infusion time program parameter and a second pre-established dosage limit for the infusion dose program parameter based upon the second selected preloaded infusion therapy and the second profile data;
providing second preset values for the program parameters based upon the second selected preloaded infusion therapy and the second profile data, the second preset values including a second numerical time value for the infusion time program parameter and a second numerical dosage value for the infusion dose program parameter; and
administering the second selected preloaded infusion therapy via the second channel of the medical pump using the second preset values of the program parameters.

13. The method of claim 12 , further comprising administering the selected second infusion therapy after the originally selected preloaded infusion therapy.
