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.
Claims21
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 operations comprising:
- receiving, on the primary microprocessor executing one or more applications written in a first computer language, an initial command processable by the one or more applications written in the first computer language;
- converting the initial command into a modified command processable by one or more applications written in a second computer language;
- and
- providing the modified command to the safety microprocessor executing the one or more applications written in the second computer language.
An infusion pump assembly comprising:
- a reservoir assembly configured to contain an infusible fluid;
