Abstract: An intermittent medical gas or oxygen delivery and regulator valve system which utilizes a single diaphragm and allows medical gas delivery through a central path in a valve stem. The valve may be easily retrofit to nearly all medical gas delivery systems currently in use and is thus expected to have widespread commercial appeal. The boundary between the valve stem and valve shuttle is of a novel design which results in a virtually frictionless movement by the shuttle element. The combination of elements results in a simplified and more efficient, long-life design.

Abstract: A portable pressurized gas delivery system with impact protection includes a pressure regulator device comprised of a shut-off valve/refill portion, a pressure regulation portion and a flow control portion. The pressure regulator device is attached via a mating machine threaded portion to a high pressure gas vessel or tank. An adapter or flange washer is situated between the regulator device and tank. A u-shaped handle is attached to the flange washer and extends along side and beyond the height of the gas pressure regulator. A circular ring is transversely attached to the u-shaped handle and situated to surround the regulator device thereby providing impact protection from all directions for the gas pressure regulator device. The pressure regulator device and flange washer include mechanical alignment mechanisms so that angular alignment of the devices is established.
