Smart Syringe Pump Project Project Objective: To design and develop a highly precise automated injection system for use in intensive care units (ICUs) and operating rooms, where it is necessary to inject very small amounts of highly sensitive medications (such as anesthetics or insulin) at constant speeds that are impossible for the human hand to achieve. Supervised by Professor Dr. Amir Najah Saud 1. Engineering and Physical Principle: The device relies on converting the rotational motion generated by the motor into very precise linear motion. • Stepper Motor: Characterized by its ability to move at very small angles (steps), allowing for precise control of the piston thrust to micrometers. • Lead Screw: Responsible for converting the motor's rotation into a horizontal displacement that drives the syringe piston, ensuring a continuous flow of fluid without oscillation. 2. Technical Components (as shown in your images): • Arduino Uno Board: The brain that receives commands and sends pulses to the motor. • Motor Driver (A4988 or equivalent): The small red component shown in the images, which provides the motor with the power needed to move. • 16x2 LCD Screen: Displays the flow rate (mL/min) and the total volume injected. • Push Buttons: For adjusting the speed or manually starting and stopping the device. • Linear Motion Structure: As clearly shown in your images, metal rods and a screw gear are used to ensure straight and precise movement. 3. Medical Importance: • Accuracy: Avoids human error in calculating drug doses. • Consistency: Maintains a constant level of the drug in the patient's blood throughout the treatment period. • Safety: Option to add alarm sensors in case of tubing blockage or depletion of the fluid. Summary of work: You have successfully translated theoretical principles in mechatronics into a biomedical model capable of controlling a patient's life
