PEEP = Positive End-expiratory Pressure Valve
This is an experimental, highly configurable PEEP valve design (for 22mm tube systems), which can utilize a spring or a rubber band to maintain the opening pressure level.
PEEP valves are used in ventilation systems, to maintain ~20cmH2O pressure in the hood. The initiative for the design came from a FB discussion on chances to 3D print a PEEP valve to non-invasive ventilation systems - to increase the capacity in case a commercial valve is not available on the market due to the COVID19 situation.
The original idea - to use a ping-pong ball as a valve coming from James Rink (surgeon in the UK), and this is a solution proposal from my side to his idea.
The design - by intention, built only on standard components, like a flat-seal from garden pipe system, a ping-pong ball, rubber band, standard springs.
Most parameters can be configured, like ball diameter, ball clearance, thread clearance, thread pitch, connecting tube paramet
