Simple design and manufacturbale with very simple material · 模型 164354
I am a Mechanical Engineer and i work with team from tunisia were we can be of assistance on some of the parameters that might be needed in a design. COVID patients that need a ventilator are intubated. Depending on the circumstance they may be breathing on their own, but also may not. They have a particular type of diffuse lung injury called ARDS (acute respiratory distress syndrome). These patients often need a ventilator that can administer what is called lung protective ventilation. Overexpansion of an already damaged lung can damage it further. They need to be able to deliver a particular volume, with peak and plateau pressure limited, and also be able to provide PEEP (or positive end expiratory pressure). Nonetheless, a simple ventilator could provide a stopgap until a more capable ventilator could be freed up. The concept of using two patients on one ventilator is very problematic. Imagine the lung of the patient is a balloon. If the balloons have equal compliance (or stiffness) and you try to blow them up with one straw then they may blow up equally. Now imagine that the lungs of one patient get stiffer (this is what happens as the lungs continue to fail) then the other patient. You blow into both those patients, the less stiff lung patient will preferentially get more of that flow, while the one with the stiff lung gets progressively less and less ventilation. You could be damaging the lung of the healthier patient with the excessive flow, while at the same time losing ventilation to the sicker patient
