Ventilator Y Connector - No Supports

<p>UPDATE 02APR20: Connector passed flow tests on an artificial lung with flying colors. See it in action: <a href="https://www.youtube.com/watch?v=q26rXmtEKhk&amp;feature=youtu.be">https://www.youtube.com/watch?v=q26rXmtEKhk&amp;feature=youtu.be</a></p> <p>I got my hands on some ventilator parts to get actual dimensions. The model my local hospital uses has one branch different from the others, so I modified my parametric design to accommodate. I also ensured that it will print without supports to make these more easily produce-able. Same rules apply:</p> <p>A doctor friend mentioned a possible shortage of Y junctions for ventilator hoses especially if it became necessary to service multiple patients off of one machine (like so:<br/> <a href="https://hackaday.com/2020/03/19/saving-4-patients-with-just-1-ventilator/">https://hackaday.com/2020/03/19/saving-4-patients-with-just-1-ventilator/</a>). Feel free to utilize or mod as needed.</p> <p>Safety considerations:<br/> -Use at your own risk...something something neither liable nor responsible...something something...<br/> -3D printed items can be porous and permeable<br/> -Recommend checking the SDS of whatever you print for particulates and hazardous volatile compounds<br/> -This will be an inferior/less desirable solution than similar parts from approved sources<br/> -Pretend that you have COVID-19 when moving the part from the print bed to a sealed container for delivery<br/> -I fly helicopters and ride motorcycles, so my perception of acceptable risk likely doesn't match yours or the FDA's.</p>
