Respirator Valve

Respirator valve & respiratory valve is generally umbrella check valve, also known as umbrella valve seal, mushroom valve, which is a non return one way valve and used in air inlet & intake valve for self inflating bag, manual resuscitator, bag valve mask(BVM), manual resuscitation & ventilation bag like Ambu Bag, Laerdal resuscitator. Respirator valve & respiratory umbrella valve is made from medical grade silicone by compression molding or liquird silicone rubber LSR molding.

Medical Umbrella Valve for Respiratory Device


Respirator Intake & Inlet Valve Working Principle 

When the pressure on the side of the umbrella mouth of the umbrella-shaped diaphragm is greater than the pressure at the end of the umbrella top, the umbrella surface receives the pressure in the direction of the umbrella mouth. This pressure causes the umbrella mouth to deform and expand. There is a gap between the valve diaphragms, so that the gas can be discharged through the vent hole and the gap between the end face of the valve body and the umbrella diaphragm to function as a one-way valve (check valve).

Umbrella Check Valve Working Principle in Bag Valve MakBag Valve Mask Ventilation's mushroom umbrella valve seal

All in one intake valve includes three umbrella valves (mushroom seal valve) with different diameters. Their diameters are 20mm, 24mm and 34mm. These valves are non return one way valve which are made of medical grade silicone, and function as gas intake and air inlet &outlet check valve. 

Gas intake valve closes during bag compression, permitting positive-pressure ventilation. The bag is refilled by flow through the fresh gas inlet and across the intake valve. Connecting a reservoir to the intake valve helps prevent the entrainment of room air. The reservoir valve assembly is really two unidirectional valves: the inlet valve and the outlet valve. The inlet valve allows ambient air to enter the ventilation bag if fresh gas flow is inadequate to maintain reservoir filling. Positive pressure in the reservoir bag opens the outlet valve, which vents oxygen if fresh gas flow is excessive.
