摘要:
Respiratory apparatus for medical use is disclosed comprising a housing (11) having a first inlet (13) for connection to a source of gas under pressure, second inlet means (16,16) for the entrainment of air and an outlet (22) for supplying the gaseous mixture to a patient. The second inlet means (16,16) is adjustable by means of a ring (17) rotatable around the upper part of the housing (11). The ring (17) is spring loaded to bring a lower end thereof into contact with a shoulder (21) of the housing (11). This lower end and the shoulder (11) have formations (20) which will inter-engage to prevent rotation of the ring (17) but which may be disengaged to permit rotation of the ring (17) if the ring (17) is lifted against the action of the spring (19).
