Abstract:
1. A manifold system for compressed medical gases comprising: a first input supply line and a second input supply line, wherein the first input supply line is adapted to receive a first medical gas from a first supply of compressed medical gas, wherein the second input supply line is adapted to receive a second medical gas from a second supply of compressed medical gas, wherein the first input supply line and the second input supply line are operative to direct the first and second medical gases to a common location; at least one output supply line coupled to receive medical gas from the common location; a first primary pressure regulator in operative connection with the first input supply line, wherein the first primary pressure regulator is configured to reduce the pressure of medical gas flowing through the first primary pressure regulator to a first intermediate level; a second primary pressure regulator in operative connection with the second input supply line, wherein the second primary pressure regulator is configured to reduce the pressure of medical gas flowing through the second primary pressure regulator to a second intermediate level, wherein the first intermediate level is higher than the second intermediate level; a check valve between the second primary pressure regulator and the common location; a solenoid valve in operative connection with the first input supply line, wherein the solenoid valve is operative to switch between an open state and a closed state, wherein in the open state the solenoid valve is operative to permit the first medical gas from the first supply to flow through the solenoid valve to the common location, wherein in the closed state the solenoid valve is operative to prevent the first medical gas from the first supply from flowing through the solenoid valve to the common location.
