Open Source Emergancy Ventilator

thingiverse

This is a 3D printed Emergency Ventilator offered under the Good Samaritan Statute during the Covid-19 emergency period. It has not been evaluated by trained medical professionals at this time. Disclaimer: Proper ventilators possess multiple sensors, safety features and have been evaluated by medical professionals. This device lacks all those things! It should only be used in a major emergency when no other option is available. Use it under supervision and with trained medical personnel who can assess its effectiveness. To clarify, if a real ventilator is accessible, always use that instead. Improper use of this device could lead to fatal consequences. Despite these warnings, this device can compress an emergency ventilator bag with a selectable degree of force based on the holes you choose to use. Assembly instructions and Bill of materials will be provided soon. For now, if you print one, you'll need a NEMA 17 stepper motor, a motor controller, and a power supply with a rheostat, along with various lengths of M5 bolts and nuts, some M5 washers, an M8 bolt and nut, several M8 washers, and at least one standard M3 nut for the stepper. The STEP files are available for modification according to your needs. The goal of this project is to ensure that a ventilator can be made available in remote areas with 3D printing capabilities.
