Abstract
The construction of an Arduino Uno based syringe pump with the ability to measure the patient's body temperature during injection and detect the contrast material bubble has not been done so far. A syringe pump is a device that controls the volume and flow of milliliters to microliters for a certain period of time with very high precision, which gradually pushes the injection piston. This use of syringe pump for drug administration has been done for years. The working principle of this system consists of installing two steel rods to push the syringe piston at a set speed, which works through a coupling system. The advancement of technology has made it possible to use a motor as the driving force of the syringe filled with liquid released through the needle, and the electronic system in this tool is used as a controller. The design using a stepper motor based on Arduino Uno is chosen to adjust the flow rate; the research includes two stages of software and hardware construction. The hardware is implemented with the components needed to build a syringe pump with an Arduino Uno as the brain of the system and a stepper motor as a piston pusher.The flow rate in the syringe pump can be adjusted with the keyboard and displayed on the screen. It is also possible to see the patient's body temperature on the screen, and to detect bubbles in the contrast liquid during injection, we also put a sensor in this device that alerts the operator.
