Here is the rewritten text: Individual PEEP Valve for use in shared ventilation allows personalized adjustment of PEEP levels in each circuit. FDA and medical societies have not approved this device. Use at your own risk and liability. Printing Part: Five parts are printed for the PEEP Valve Assembly. They include: 1. Valve Body 2. Flapper Valve Plate 3. Adjustment Screw Plate 4. Cover 5. Knob Design of the parts was completed using SolidWorks 2020. Software used for printing was PrusaSlicer 2.2.0. Printers were from Prusa, both i3 MK2 and i3 MK3's. Parts are made out of PLA (Poly Lactic Acid) but could very well be made out of PETG (Poly Ethylene Terephthalate Glycol) or (PP) Polypropylene. Supports were only used in the printing of the vertical (input) passageway of the Valve Body. This insured a flat surface for mounting the rubber flapper valve. Generating supports in PrusaSlicer produces complete model supports, but using support blockers allows programmers to adjust supports and in this model, just below the flat perforated mounting plate for the flapper valve. Print Settings were 5 top and 5 bottom horizontal shells, 3 vertical shells. Infill was 50%. Print time was typically just under 5 hours to print all parts at the same time. Material cost (PLA) is about $1.06, making this PEEP valve assembly potentially disposable. PEEP Valve Characteristics: Small size Significantly smaller than any other 3D printed PEEP valve Easy to use, handle and adjust Requires less printing material Takes less time to print Easily modifiable Readily available parts include: GE part number 0211-1454-100, Free breathing flapper valve Tractor Supply spring kit #2, compression spring 10-32 x 1in Philips head screw and nut Other suitable parts can also be substituted. Features standard 22mm conical connections: Easily adaptable to any configuration with standard patient set, filter, ventilator, etc. Disposable Very inexpensive to produce Can be used as a check valve
