A device for connecting a respirator or an anesthesia machine to a patient comprises a hose (1) which is flexible along substantially its whole length, and one end (1a) of which is formed in a manner to enable it to be connected, in gas-tight fashion, to an endotracheal tube or the like, and the other end (1b) of which is formed in a manner to enable it to be connected, in gas-tight fashion, to the Y-piece of the respirator or anesthesia machine. Incorporated in the part of the hose (1) located nearest the aforementioned other end (1b) is a flexible heat and moisture exchanger body (2) which fills substantially the whole of the cross-sectional through-flow area of the hose (1) and which is substantially uniformly permeable to a gas flow. The heat and moisture exchanger body (2) advantageously comprises a homogenous felted material impregnated with a hygroscopic substance and an anti-bacteria agent. The hose (1) together with the heat and moisture exchanger body (2) incorporated therein form a disposable unit. |
