Description
The inhaler is a hollow, metal cylindrical instrument with two hollow metal tubes leading to two plastic anaesthetic delivery cups; at the bottom of the cylinder, there is a metal cap that was once removable; it has gripping lines stamped into the metal and two vertical rectangular slots on opposite ends of the diameter of the cap; the bottom of the cap is flat; a metal disk caps this cylinder; from the curved top of this disk, two hollow metal tubes extend, curving outwards slightly away from each other, and forwards; these tubes are each capped by a brown plastic applicator; each applicator has a rounded conical shape with a round hole at the top.

Description
Anaesthesia mask (a) and attachment (b); both components are largely comprised of solid, smooth, metal wires; the mask (a) is a circular frame with a looped arm at one end; four thinner wires are attached to each side of the frame, so that they intersect at a midpoint; several fabric threades tie the wires together at the midpoint; the frame tapers at one end to form the looped arm; a thin band of metal holds the wires together, and they separate at the other end of this band and form a loop; a small, round, solid metal rod extends from the outer surface of this band, and is capped by a metal button; attachment (b) joins the mask by this button; (b) is composed of one thin round wire; it is roughly the same size and shape as the frame of (a); the metal arm extending from (b) is much shorter than the arm of (a); it extends only as far as the button on the mask, and there is no flat band of metal joining its wires.

Research Facts
The four flow meter gauges at the front regulate the flow of nitrous oxide, cyclopropane, carbon dioxide and oxygen and were very inaccurate; carbon dioxide was used to stimulate patient respiration thus allowing quicker anaesthetizing; this model allows for two cylinders each of oxygen, nitrous oxide and carbon dioxide; this was an improvement over earlier models, as cylinders sometimes ran out of gas during operations; it was difficult to determine when the oxygen cylinder was empty and nitrous oxide pressure falls very quickly; with this model, if a tank ran dry, the patient could immediately be changed over to a full tank; another improvement was that the tanks were bigger than those in earlier models; the principle of this machine is the same as other machines in the same era; the regulators are single-stage regulators.

Research Facts
The Walton Apparatus was a demand flow anaesthetic machine; this was an improvement over earlier machines, because gas was used only when the patient breathed (less gas was used); this is a British-made machine and better than North American models of similar type; the British were ahead of North America in advances in anaesthesiology in this time period; the gas hose connectors at the back would have been for very big cylinders of oxygen and nitrous oxide;the emergency oxygen button is an oxygen flush button; this machine is a gas blender unit with a system to deliver a precise % of oxygen in an oxygen and nitrous oxide gas mix; the mercury pressure knob is a pressure gradient knob; the flow is pressure dependent
