Abstract
204,674. Drõger, A. B. Sept. 26, 1922, [Convention date]. Addition to 194,308. Mixing-valves; plug cocks.-Relates to apparatus for administering mixed anµsthetic gases, as described in the parent Specification, wherein the proportion of each gas in the mixture is determined by the relative pressure at which it is supplied to a valve whereby the quantity of mixture passing is varied by means of simultaneously and similarly variable ports for the two gases, and consists in so constructing the valve that each gas flows through a variable number of orifices each of the same size instead of through a single orifice of variable size, and in the provision, between the valve and the facepiece, of a multiple way cock so that the mixed gases may be administered either alone or with a. second anµsthetic such as ether, or ether alone or air alone may be supplied to the facepiece. The mixing-valve is formed with inlets q, s connected to arc-shaped chambers r, t with which one, two or more apertures u, v all of equal size and arranged in two series may be caused to register to allow the gases to pass through a mixing chamber p to the outlet w. This construction of valve permits the use of pressure gauges each with a single scale instead of with a series of scales as in the parent Specification. Between the'outlet wand the facepiece is arranged a multiple-way plug cock, Fig. 5, having inlets y, z, z<1> for the mixed gases, air, and ether respectively and an outlet z<2> connected to the facepiece
