Abstract
A breathing system includes a tank for pressurized breathing gas, at least one regulator comprising a connection to which the tank is attachable, a universal air connector in fluid connection with the connection, and at least one light source, the light source, when illuminated, providing a guide to connect a connector in fluid connection with a secondary tank to the universal air connector to supply breathing gas to the tank.
Claims18
A breathing system, comprising:
- a tank for pressurized breathing gas;
- at least one regulator comprising a connection to which the tank is attachable;
- a universal air connector in fluid connection with the connection;
- a controller;
- and
- at least one light source in operative connection with the controller;
- the controller being operative to place the light source in an ON state when the universal air connector is not connected to a universal connector in fluid connection with a secondary air supply to provide a guide to connect the universal connector in fluid connection with the secondary air supply to the universal air connector to supply breathing gas to the tank, wherein the at least one light source is positioned to illuminate at least a portion of the universal air connector or to illuminate a portion of a base area surrounding the universal air connector when in the ON state.

A method, comprising:
- providing a breathing system comprising a tank for pressurized breathing gas;
- at least one regulator comprising a connection to which the tank is attached and a universal air connector in fluid connection with the connection;
- illuminating at least one light source operatively connected to the breathing system when there is no universal connector in fluid connection with a secondary air supply in connection with the universal air connector to provide a guide to connect a connector in fluid connection with the secondary air supply to the universal air connector to supply breathing gas to the tank by illuminating at least a portion of the universal air connector or by illuminating a base area of the universal air connector via the at least one light source;
- and a controller in operative connection with the at least one light source, wherein the controller is operative to place the light source in an ON state.
