Medical Suction Machine Project Supervised by: Dr. Amir Najah Saud, Ms. Zahraa Mohammed Kadhim, and Mr. Mohammed Abdul Karim Razouqi A medical suction machine (or suction device) is an indispensable tool in medical applications. It is used to remove unwanted fluids (such as mucus, blood, or surgical fluids) from a patient's body to clear the airway or irrigate the surgical area. 1. Basic Operating Principle The device operates on the principle of negative pressure (vacuum). A motor creates a low-pressure area inside the collection jar, which draws fluids from the patient's body through a catheter into the collection jar. 2. Technical Components (as shown in the images): • Collection Jar: The images show the cylindrical jar designed to receive the drawn fluids. • Digital Control System: The use of an LCD screen and a microcontroller (likely an Arduino) is evident in the display of the pressure level or operating status in real time. • Connecting Tubes: The flexible, transparent tubes shown in the model, which transfer the fluid from the treatment area to the collection jar. • Protective Box: The electronic components and pump are housed in a sealed white box to ensure electrical insulation and protection from fluids. 3. Medical Importance and Features: • Airway Clearing: Essential for patients experiencing difficulty breathing due to fluid accumulation. • Precision and Control: The software allows for precise control of suction power to suit the patient's condition (light suction for children or strong suction for general surgery). • Compact Design: Your model is portable and easy to use in emergency situations. Conclusion: You have successfully developed a practical model that integrates biomechanics and electronic control, providing an effective and safe method for managing medical fluids. This is an excellent application of biomedical engineering principles in healthcare
