A compressible respiratory gas hose system interconnects a breathing gas source 101 and a patient interface device. The hose system has an open position when a breathing gas flow from the gas source is conducted to the patient interface device and a closed position when the gas flow is blocked. The aforesaid hose system comprises: (a) a first connector connectable to the gas source; (b) a second connector connectable to the patient interface device; (c) a resilient helical support member, mechanically interconnecting the first and second connectors; (d) a flexible envelope accommodating the support member and providing gas interconnection between the first and second connectors; and (e) a rod reconfiguring the support member from the relaxed long position to the compressed storage position and vice versa. |
