PANDAcase bottle - PEEP valve enclosure
Description
Team PANDA [Zurich, Switzerland]: We propose a **partly 3D printed, transparent enclosure for a commercial PEEP valve** with 30 mm female or 22mm male connection which can be integrated into a tube system with 22 mm conical connections (anaesthetic/respiratory equipment). These inline valves are needed in differential multiventilation setups for treating covid19. See this link for more information on differential multiventilation: https://www.differentialmultivent.org **This is NOT a medically approved device and is not intended for medical use.** To get it tight, an O-Ring ID 58 mm x D 3 mm or smaller is needed. Neither the bottle nor the PEEP valve are designed by Team PANDA and part of this thing. For a 3d printable PEEP valve see PANDApeep: Inline version: https://www.thingiverse.com/thing:4316582 Gen2: https://www.thingiverse.com/thing:4250354 Gen3: https://www.thingiverse.com/thing:4278384 **PRINTING/ASSEMBLY** This design works fine with a Swiss 0.45 l Coca Cola bottle (upper half). For other bottles, please remix the design using the included STEP-file. The tolerances of the 22 mm connectors must match each other and these are different for most 3D printers. If it doesn’t fit, scale it in Cura in X,Y-direction only, in small increments and write down your adjustments for further printing. To prevent the bottle from slipping over the O-ring due to overpressure, the bottom rim can be heated and will bend inwards. If the valve is not turnable with the bottle, heat the contact area to get a tight fit or use tape on the valve cap to increase friction. **MATERIAL** We used PLA with a 0.4 mm nozzle for all parts. No support needed if printed as seen in the picture. https://youtu.be/5y7_122ZFO8
