Syring Pump Equipped with Nearly Empty and Occlusion Based sensors Microcontroller ATmega 2560 (Occlusion)

Abstract

Syringe pump is tool functional medical​ for do injection fluid drug in a way continously with objective therapeutic nor diagnostic. Use of installed syringe pump in a way sustainable can cause happen occlusion causes​ fluid incoming medication​ to in body No flow in a way constant and formed pressure great on syringe and flow liquid that if left will happen swelling. On tools This uses the FSR402 sensor as detector occlusion. Apart from that, the A4988 driver is also used as stepper motor controller whose speed can customized in accordance with specified settings.​ Arrangement done on the Nextion TFT LCD which is this TFT can Also used as a display tool. This tool aim For help enter dose drug in a way slowly in accordance with specified speed​ with exists detector occlusion as detector If exists blockage. This tool use 20 ml and 50 ml syringes which is the target volume can customized start from 0 – 50 ml with flow rate 5 – 50 ml/hour with addition multiples of 5. Testing done with IDA 4 Plus tool with results that is; the average error value for 20ml syringe was 0.2% with the largest error occurs at a Flowrate of 10 ml/hour, namely 0.5% and the smallest error occurs at a volume of 50 ml/hour, namely 0.1%. And to 50ml syringe, the average error value is 0.13% with the largest error occurs at a flowrate of 20 ml/hour, namely 0.2% and the smallest error occurs at a volume of 10 ml/hour, namely 0.07%. Occlusion sensor testing required​ For change the occlusion sensor is 10 Psi.
