The design and construction of infusion pump calibrator

The purpose of this research was to study on the design and construction of infusion pump calibrator. This research has adopted the principle of physics, electronics and microcontroller. The designed and constructed the infusion pump calibrator was composed of three main parts: 1)the control part consisting of micro switches for selected the operating mode, 2) signals detection part composing of load cells, pressure sensor for measuring flow rate and occlusion alarm respectively and 3) the processing and display part comprising of microcontroller AVR ATmega1280 with C Language program and LCD sequentially. The results of functional testing were compared with standard infusion devices analyzer Metron Lagu showed that the average percentage error of flow rate measuring and occlusion pressure tests were 0.45 percent and 0.21 percent successively.
