This is a revolutionary CAD design for a cutting-edge mechanical ventilator tailored for mass casualty situations and impoverished areas with limited resources. The device delivers life-giving breaths by expertly compressing a standard bag-valve-mask (BVM) using a precision-engineered pivoting cam arm, thus eliminating the need for human intervention in operating the BVM. A pioneering initial prototype is crafted from high-quality acrylic, powered by a reliable 14.8 VDC battery and boasting an adjustable tidal volume of up to a maximum of 750 ml. Crucially, tidal volume and breaths per minute are effortlessly set via intuitive user-friendly input knobs. The innovative prototype also features an assist-control mode and a vital alarm system to detect overpressurization of the entire system. Future iterations will incorporate an advanced controllable inspiration to expiration time ratio, a pressure relief valve, PEEP capabilities, and a high-resolution LCD screen. Through this groundbreaking prototype, the strategy of cam-actuated BVM compression is conclusively proven as a viable solution for creating low-cost, low-power portable ventilator technology that provides essential life-saving features at a fraction of the cost of existing technology.
