Abstract

An adjustable gas flow regulator device primarily for use in medical care, said device comprising a two-part body (8/25) having a high pressure gas inlet connector (1) and a gas outlet connector (16) mounted thereon. Mounted within the body is a conventional regulator comprising a piston (9) axially movable in a stepped bore (46/47). Mounted between the output of the regulator and the outer connector (16) is a flow selector device comprising a flow selecting member (13) rotatable by means of a knob (31). The flow selecting member (13) is formed with a plurality of radially extending bores (54) in the outer part of each of which is fitted a setting plug which may be externally adjustable by a tool (not shown). The inner part of each bore forms part of the route by which gas passes to the outer connector and the flow of gas through each such inner part can thus be adjusted by means of the setting plug so that, at each respective angular position of knob (31), a different flow setting can be obtained, as necessary.
