Metal Medical Non Rebreather Rubin Valve

The Rubin valve is a type of non-rebreather valve used in anesthesia circuits and breathing systems. It's designed to ensure unidirectional flow of gases, preventing the rebreathing of exhaled gases by the patient. However, it's not typically associated with metal components.

If you're referring to a Rubin valve with a metal component, it's possible that the valve housing or some internal components may be made of metal for durability or other reasons. However, the core function of the Rubin valve is to regulate gas flow and prevent rebreathing, regardless of the material used in its construction.
