Breathing apparatus with illuminated connection
View Patent ↗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.
1. 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.
2. The breathing system of claim 1 further comprising a first stage regulator comprising the connection and a second stage regulator in fluid connection with the first stage regulator.
3. The breathing system of claim 1 further comprising a pressure sensor in operative connection with the controller, the pressure sensor being in fluid connection with the tank, the controller placing the light source in the ON state upon receiving a signal from the pressure sensor indicating that a pressure in the tank is at or below a predetermined first pressure.
4. The breathing system of claim 3 wherein the controller places the light source in an OFF state upon receiving a signal from the pressure sensor indicating the pressure in the tank is at or above a predetermined second pressure.
5. The breathing system of claim 3 wherein the controller places the light source in an OFF state a predetermined period of time after receiving a signal form the pressure sensor indicating the pressure in the tank is at or above a predetermined second pressure.
6. The breathing system of claim 1 wherein the at least one light source projects light which is incident upon the universal air connector; the at least one light source is positioned upon a portion of the universal air connector, or the at least one light source is positioned at a base of the universal air connector.
7. The breathing system of claim 1 wherein the at least one light source is spaced from the universal air connector and projects light which is incident upon the universal air connector.
8. The breathing system of claim 7 wherein the at least one light source is positioned no more than 12 inches (0.3408 meters) from the universal air connector.
9. The breathing system of claim 7 wherein the at least one light source is positioned no more than 4 inches (0.1016 meters) from the universal air connector.
10. 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.
11. The method of claim 10 wherein the breathing system further comprises a first stage regulator comprising the connection and a second stage regulator in fluid connection with the first stage regulator.
12. The method of claim 11 further comprising sensing pressure in the tank via a pressure sensor in operative connection with the controller, the pressure sensor being in fluid connection with the tank, the controller placing the light source in the ON state upon receiving a signal from the pressure sensor indicating that a pressure in the tank is at or below a predetermined first pressure.
13. The method of claim 12 wherein the controller places the light source in an OFF state upon receiving a signal form the pressure sensor indicating a pressure in the tank is at or above a predetermined second pressure.
14. The method of claim 12 wherein the controller places the light source in an OFF state a predetermined period of time after receiving a signal form the pressure sensor indicating the pressure in the tank is at or above a predetermined second pressure.
15. The method of claim 10 wherein the at least one light source projects light which is incident upon the universal air connector, the at least one light source is positioned upon a portion of the universal air connector, or the at least one light source is positioned at a base of the universal air connector.
16. The method of claim 10 wherein the at least one light source is spaced from the universal air connector and projects light which is incident upon the universal air connector.
17. The method of claim 16 wherein the at least one light source is positioned no more than 12 inches (0.3048 meters) from the universal air connector.
18. The method of claim 16 wherein the at least one light source is positioned no more than 4 inches (0.1016 meters) from the universal air connector.
