Abstract:
1. An infusion pump for pumping fluid though an administration set at a constant flow rate over a long duration, the pump comprising: a pumping mechanism configured for pumping fluid, said pumping mechanism operating at a pulse frequency; and a controller for controlling said pulse frequency of said pumping mechanism; and one or more sensors capable of measuring at least one characteristic value relating to a status of said pumping mechanism; said controller configured for operating said pumping mechanism at a first pulse frequency; said one or more sensors measure said at least one characteristic value intermittently; and wherein when said at least one characteristic value meets a threshold value, said controller causes said pumping mechanism to operate at a second pulse frequency, said second pulse frequency being different from said first pulse frequency; wherein said threshold value is calculated based on a material used to form the administration set.
