Abstract

An infusion pump assembly includes a reservoir assembly configured to contain an infusible fluid. A motor assembly is configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly. Processing logic is configured to control the motor assembly. The processing logic includes a primary microprocessor configured to execute one or more primary applications written in a first computer language; and a safety microprocessor configured to execute one or more safety applications written in a second computer language.

Claims

1. An infusion pump assembly comprising:

a reservoir assembly configured to contain an infusible fluid;

a motor assembly configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly;

processing logic configured to control the motor assembly;

wherein the processing logic includes;

a primary microprocessor configured to execute one or more primary applications written in a first computer language; and

a safety microprocessor configured to execute one or more safety applications written in a second computer language that is different than the first computer language; and

a computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform the operation of processing a command written in the first computer language received on the primary microprocessor so that the command may be confirmed by the safety microprocessor executing the one or more safety applications written in the second computer language.

2. The infusion pump assembly of claim 1 further comprising:

a primary power supply configured to provide primary electrical energy to at least a portion of the processing logic; and

a backup power supply configured to provide backup electrical energy to the at least a portion of the processing logic in the event that the primary power supply fails to provide the primary electrical energy to the at least a portion of the processing logic.

3. The infusion pump assembly of claim 1 wherein:

the primary power supply is a first battery; and

the backup power supply is a super capacitor assembly.

4. The infusion pump assembly of claim 1 wherein the processing logic includes one or more circuit partitioning components configured to divide the processing logic into primary processing logic and backup processing logic.

5. The infusion pump assembly of claim 4 wherein the primary processing logic includes the primary microprocessor.

6. The infusion pump assembly of claim 4 wherein the backup processing logic includes the safety microprocessor.

7. The infusion pump assembly of claim 4 wherein the one or more circuit partitioning components includes one or more of a diode assembly and a current limiting assembly.

8. The infusion pump assembly of claim 7 wherein the diode assembly is configured to allow the primary power supply to charge the backup power supply while prohibiting the backup power supply from providing backup electrical energy to the primary processing logic in the event that the primary power supply fails to provide the primary electrical energy to the primary processing logic.

9. The infusion pump assembly of claim 1 wherein the one or more primary applications written in the first computer language are chosen from the group consisting of an operating system, an executive loop and a software application.

10. The infusion pump assembly of claim 1 wherein the one or more safety applications written in the second computer language are chosen from the group consisting of an operating system, an executive loop and a software application.

11. The infusion pump assembly of claim 1 wherein the primary power supply is configured to provide electrical energy to one or more subsystems included within the infusion pump assembly.

12. The infusion pump assembly of claim 1 wherein the primary power supply and the backup power supply are configured to provide electrical energy to an audio system included within the infusion pump assembly.

13. The infusion pump assembly of claim 1 wherein the audio system is configured to provide an escalating alarm sequence in the event of a loss of a beacon signal, wherein the escalating alarm sequence includes at least a low-intensity alarm and a high-intensity alarm.

14. The infusion pump assembly of claim 1 wherein the first computer language is chosen from the group consisting of Ada, Basic, Cobol, C, C++, C#, Fortran, Visual Assembler, Visual Basic, Visual J++, Java, and Java Script.

15. The infusion pump assembly of claim 1 wherein the second computer language is chosen from the group consisting of Ada, Basic, Cobol, C, C++, C#, Fortran, Visual Assembler, Visual Basic, Visual J++, Java, and Java Script.

16. An infusion pump assembly comprising:

a reservoir assembly configured to contain an infusible fluid;

a motor assembly configured to act upon the reservoir assembly and dispense at least a portion of the infusible fluid contained within the reservoir assembly;

processing logic configured to control the motor assembly;

wherein the processing logic includes;

one or more circuit partitioning components configured to divide the processing logic into primary processing logic and backup processing logic;

a primary microprocessor included within the primary processing logic and configured to execute one or more primary applications written in a first computer language; and

a safety microprocessor included within the backup processing logic and configured to execute one or more safety applications written in a second computer language that is different than the first computer language; and

a computer program product residing on a computer readable medium having a plurality of instructions stored thereon which, when executed by a processor, cause the processor to perform the operation of processing a command written in the first computer language received on the primary microprocessor so that the command may be confirmed by the safety microprocessor executing the one or more safety applications written in the second computer language.

17. The infusion pump assembly of claim 16 wherein the one or more primary applications written in the first computer language are chosen from the group consisting of an operating system, an executive loop and a software application.

18. The infusion pump assembly of claim 16 wherein the one or more safety applications written in the second computer language are chosen from the group consisting of an operating system, an executive loop and a software application.

19. The infusion pump assembly of claim 16 further comprising:

a primary power supply configured to provide primary electrical energy to at least a portion of the processing logic; and

a backup power supply configured to provide backup electrical energy to the at least a portion of the processing logic in the event that the primary power supply fails to provide the primary electrical energy to the at least a portion of the processing logic.

20. The infusion pump assembly of claim 16 wherein the first computer language is chosen from the group consisting of Ada, Basic, Cobol, C, C++, C#, Fortran, Visual Assembler, Visual Basic, Visual J++, Java, and Java Script.

21. The infusion pump assembly of claim 16 wherein the second computer language is chosen from the group consisting of Ada, Basic, Cobol, C, C++, C#, Fortran, Visual Assembler, Visual Basic, Visual J++, Java, and Java Script.
