Hello and good afternoon all. It is Thursday the 19th of March and I present to you the Magiva later, Mark 1. As you can probably see just by looking at this, this is a pseudo-adventilator that is built around a bag valve mask or an empty bag as some of you folks may have heard about it. This is coupled together from commonly available parts. There's nothing too crazy here or too hard to obtain that was part of the design philosophy. You can see there's plywood, there's two by fours, there's some velcro, probably the most complex parts here are the skateboard bearings or roller blade bearings that are on the little metal axles that push down on the central PVC compression lever as well as the DC motor that's driving it all and the little PWM module that helps control the rate but both the electronic parts there are just sourced through Amazon and easily available. But again the idea is that this is a disaster scenario, quote unquote ventilator and or for low-resourced areas. I hope we never end up in a situation where we have to use this but I felt sort of compelled the last couple days to try to throw this together. To be clear I am not a critical care pulmonary doc. I'm also not an anesthesiologist nor am I a mechanical engineer. I am just a anxious pediatrician trying to channel my anxiety into some way productive and so this is what we came up with here. Again this is all very simple stuff, nothing too complicated, there's no real leverage down here, this is just pure PVC and a T connector. The bag valve mask is just held in place with the valve crow and you can get a little look at the rotation mechanism and the pushing mechanism up there. Rate is controlled at the PWM module here, you can turn the rate up and down if you want to have an even slower rate you could take off one of the compression axles there, one of the pushing axles there and basically have the rate. Your tidal volume can be controlled by moving the actual motor up and down the mount and that's just held in place that couple of wing nuts and so you can move that down relatively easily. So you have control over tidal volume as well as rate. If you stuck a peep valve on this you could have some peep and as well as I'm probably gonna get an idea of what your inspiratory pressure would be and of course your FiO2 and humidity and such would be controlled by whatever you feed into this and humidity I imagine you could add onto the end of this. I decide to build around the bag valve mask because that already sort of fits into the whole healthcare apparatus. I don't need to develop special fittings for that. You know this fits into the usual airweight structures that are in place. So hopefully this is helpful. I am very very open to constructive criticism, suggestions, thoughts, concerns so please feel free to contact me. Once again this is the Magiva later version one and thanks for watching and everyone stay safe out there.
