The Shaft Mechanism DIY Ventilator is a novel and inexpensive engineering solution intended for application in providing simple mechanical ventilation assistance in the presence of emergency conditions, resource-scarce settings, or engineering development exercises. It is more pertinent in settings where using mainstream ventilatory devices is difficult. The cam shaft system accurately converts rotational to reciprocal motion, enabling precise compression release in manual resuscitators like the Ambu bag, simulating natural breathing. The Shaft Mechanism DIY Ventilator emphasizes simplicity, durability, and accessible engineering.
The cam shaft mechanism assembly includes a rotational shaft, cams, follower arms, and a drive motor, converting rotational motion into linear motion through the cam’s interaction. The generated motion is necessary in compressing the resuscitation bag at a predetermined rate. It is possible to determine breaths and minutes through variation in the cam design or rate of rotation. Thus, the Shaft Mechanism DIY Ventilator has incorporated various mechanical principles.
Shaft Mechanism DIY Ventilator uses mild steel or aluminum, cam followers, bearings, and a low RPM electric motor. A sturdy base ensures accurate shaft alignment and prevents vibration. Safety housing shields the user from components in motion. Limit switches enhance patient safety by preventing bag over-pressurization. The Shaft Mechanism DIY Ventilator includes human overrides for power outages and is appreciated for its straightforward, sturdy design and minimal electronics. It is not a medical device for emergencies but serves as an emergency tool illustrating engineering applications in health crises. Proper engineering ensures its role as a demonstrative tool in life support technology.
