Mechanical BVM Ventilator V2 · 模型 63381
Taking inspiration from the work done by MIT students in 2010 and the current crisis, developed this Version 1 of a mechanically operated Bag-Valve-Mask based ventilator. The intention was to make it able to be rapidly developed, manufactured and shipped using simple processes and off the shelf components where possible. NOTE: Tolerances are currently set to account for laser cutting of acrylic panels, I will upload a file to suit the files being cut on a flatbed router/ 3D Printed at a later point. The difference is about .2 - .3mm in the overall diameters. The initial prototype has been produced with V2 in the works. Expecting to start medical trials shortly in conjunction with local universities and medical staff. The Programming will be linked once the Programmer has finished and uploaded the code. In addition, I have borrowed a lot of CAD for the 'off the shelf' components, I will provide links to those component's creators when I have some time. Finally, if you require any specific information, please comment/ pm me and I'll answer as I can. Update 20/04/2020 V2 is now 98% finalized, unfortunately life has caught up with me and I have exams next week so this has to be placed on hold until they're finished. *I have uploaded the assembly STEP which gives access to the model, it just means you would have to extract them piece by piece to use them. My apologies in advance for that. * primary belt tensioner is a work in progress. * There is an additional dial required according to the programmer, that will be added in before final V2 model files are released. * There is a few more angle brackets required to support central uprights at the base (maybe) * Additional electronic component mounting points and electronic BOM have yet to be finalized * The idler pulley cover remains the only part needing 3D Printed, I will replace it with something generic when I have time to find something suitable. Update: 13/04/2020 First functional prototype has been completed. Please see the attached video. NOTE: * In the current iteration, the 6mm front cross support will buckle under load and cause uneven loading on the main belts and gears. I am actively working on a solution to this but you van solve it by bolting a section of right angle between the cross section and side panel. * This iteration is difficult to tension the belts correctly, I am working on incorporating a tension adjustment mechanism. * There is a need for the idler pulley to be sprung as to pr...
