Smart Breath Bag Unit and Evaluation of Vital Signs Module

Abstract

— Due to Contraction motion in the diaphragm, reverse pressure is produced. By using this reverse pressure, human lungs suck the air from the environment for breathing. Contradictory motion is used to inflate the lungs by pumping type motion. Normally, Ventilators can generate 10-12 breaths per minute. With the help of Ventilator, we can also be able to monitor patient monitoring parameters like Temperature, SPO2, Heartbeat, Electrocardiogram and Electroencephalogram. The setting to adjust the time duration for inhalation to exhalation ratio is very important. We used a silicon ventilator bag which is coupled driven by DC motors with one side push mechanism to push the ventilator bag. For switching, here we use a relay switch and a variable pot to adjust the breath length and the BPM value for the patient . The vital sign module sensor is mainly used to monitor the necessity of the patient monitoring and display the results on LCD screen. There are different types of existing systems which can be used for operating an artificial manual breath unit bag. Such as Ruler chain mechanism, CAM mechanism, Rack and Pinion mechanism, Lead screw mechanism but here using front and back mechanism with the help of wiper motor function. The ventilator we designed and improved by using Microcontroller and Wi-fi module helps us to develop a low-cost, portable, and reliable Emergency Ventilator.
