This project is my undergraduate work at Çukurova University, Mechanical Engineering Department. It designs a fully automated pneumatic tube system to transport medical samples (like blood and urine) in hospitals. The system uses compressed air, special carriers, and conveyors to move samples quickly and safely without human help. It was supervised by Prof. Dr. Necdet Geren and submitted on January 26, 2024.
To create an automated system that transports medical samples faster, safer, and with fewer errors, reducing delays and nurse workload in hospitals.
- Design: Tubes made of PVC, carriers made of borosilicate glass and polyurethane for safety and durability.
- Actuators: Six DSNU pistons (25 mm diameter) to move stations and grip conveyors.
- Conveyor: D-Series conveyor for smooth transport.
- Blower: SANYO DENKI blower for air flow (0.78 m³/min).
- Control: Automated with a pressure control valve and program logic.
- Tools: CAD for design, calculations for actuator sizing and air use.
