DESIGN AND PROTOTYPE OF AN AUTOMATED POSITIVE SUCTION MECHANICAL VENTILATOR UNDER AN ECONOMIC AND SOCIAL PROJECT ANALYSIS IN LOW-INCOME PATIENTS

The design and prototype of a low-cost portable positive pressure mechanical ventilator for use in cases mass disasters resource-limited environments are described. provides breaths by compressing conventional valve bag mask (AMBU) using pivoting lever, eliminating the need human operator AMBU. An initial was constructed acrylic, with measurements 285 x 350 250 mm weight 4.1 kg (9 lb). It is powered 12V DC battery-operated electric motor features an adjustable air volume up to maximum 750 ml. Control achieved through human-machine interface 16x2 LCD screen displaying RPM percentage speed data, which adjusted easy-to-use potentiometer. also includes overvoltage safety control mode pilot lights indicate equipment's status. Iterations device will include controllable inspiration-to-expiration time ratio, relief valve, battery bank system that allows 4 hours autonomy. manufacturing cost only $820. Through this prototype, it demonstrated lever-driven AMBU compression strategy viable option achieve low-cost, low-consumption technology essential at fraction existing
