Printable ventilator-free respiratory: Venturi Valve · 模型 199265
Discover full range of geometries in project folders! Valve uses Venturi effect to generate underpressure in a tube consisting of three parts - a convergent section (nozzle), followed by constant section (throat), ending in a gradual expansion (diffuser). Due to the oxygen flow underpressure is generated in the nozzle and air is beeing sucked into valve. Valve is powered with a stream of pure oxygen with the flow rate 10-20 lpm. Two streams are mixing in diffuser: oxygen (100% O2) + air (21% O2) resulting in high flow, high oxygen stream at the outlet. Oxygen connection: 5-6mm hose Aparature connection: ISO 5356 22M Rev. 5 FiO2 / flow: - 40 % / 60 lpm (nominal, can be regulated by o2 streams) Rev. 4 FiO2 / flow: - 40 % / 42 lpm - 37 % / 50 lpm - 34 % / 59 lpm - 30 % / 86 lpm - 28 % / 120 lpm
