The present disclosure describes a bi-valve for use with a flowmeter or other source of oxygen or other medical gas, that allows a medical practitioner to easily and quickly switch from delivering oxygen or other gas from the flowmeter or other gas source to a given mask or other device, to another mask or other device. This is accomplished far faster and easier than is done under current practice. Current practice results in the patient being off oxygen or other gas for a short, but very significant period of time, which poses a serious risk of desaturation in the patient. The bi-valve may include a casing, an inlet, and two outlets, with a knob for selecting which output the oxygen or other gas is to be delivered to. The device may be a very simple ball valve device, with the only moving parts being the knob and the ball. 1. A bi-valve for use with an oxygen or other medical gas source , the bi-valve comprising:a casing;a single inlet into which oxygen or other medical gas is introduced into the casing;dual outlets consisting of first and second outlets through which oxygen or other medical gas can be selectively output from the casing; anda knob partially contained in or otherwise attached to the casing, the knob being configured to selectively direct flow of oxygen or other medical gas from the inlet into only a selected one of the first or second outlets,wherein the bi-valve is configured to always provide flow to only one of the first outlet or the second outlet, never both, and never to provide no flow at all; andwherein the bi-valve is configured to only allow for the rotation of the knob from a first position corresponding to flow being provided to only the first outlet, to a second position corresponding to flow being provided to only the second outlet, and vice versa.2. A bi-valve as recited in claim 1 , further comprising a 3-port ball within the casing claim 1 , such that the bi-valve is a ball-valve device claim 1 , the 3-port ball including three ...
