A portable suction device comprising: a gas inlet for receiving pressurized gas from an enclosed source； a gas flow path that extends from the gas inlet to an exhaust； a suction generator that has a suction inlet, the gas flow path extending through the suction generator, such that gas flow through the flow path generates a low pressure at the suction inlet； a collection container with a collection inlet and an outlet that is coupled to the suction inlet； a suction tube that has proximal and distal ends, the proximal end being connected to the collection inlet of the collection container； a valve for controlling gas flow through the flow path, the valve having a stem that is configured to pierce the source with movement of the valve from a closed position.
