CA 2440239

An air and water hose apparatus (10 or 210) for use in an air supply system (100) for firefighters (150). The air and water hose apparatus has an air hose (32 or 232) completely within the water hose (12 or 212). The air and water hose apparatus comprises only a single length of the overall water hose of the system. This ensures that no part of the air hose is exposed to possible damage. The system supplies high pressure air to the firefighters. The system allows for easy connect and disconnect of the air and water hose apparatus to the firefighter's mask (160) and preferably can be used with standard self- contained breathing apparatus (152) having a mask and a regulator (158). A branched conduit (46) allows several firefighters to be attached to a single air and water hose apparatus.

L'invention concerne un dispositif (10 ou 210) de tuyau d'air et d'eau s'utilisant dans un système (100) d'approvisionnement en air pour pompiers (150). Le dispositif de tuyau d'air et d'eau comporte un tuyau d'air (32 ou 232) entièrement inclus dans le tuyau d'eau (12 ou 212). Le dispositif de tuyau d'air et d'eau ne comprend dans son ensemble qu'une longueur unique de tuyau d'eau, ce qui permet de garantir qu'aucune partie du tuyau d'air n'est exposée à d'éventuelles détériorations. Ce système permet d'approvisionner les pompiers en air à haute pression ; de connecter et de déconnecter facilement le dispositif de tuyau d'air et d'eau au masque (160) du pompier ; et s'utilise de préférence avec un appareil (152) respiratoire standard autonome à masque et détendeur (158). Une conduite (46) de dérivation permet à plusieurs pompiers de se connecter à un seul dispositif de tuyau d'air et d'eau.
