Abstract

Apparatus for remote inspection of oxygen containers includes an electronic circuit in communication between each container (or at various locations along a pipeline) and a remote central station. The electronic circuit is adapted to issue a signal to the remote central station that includes information about predetermined internal and/or external conditions such as the level of oxygen stored in the tank, a pressure condition of material stored in the tank, a lack of presence of the tank in an installed position, or the presence of an obstruction restricting access to the tank.

Claims

1. A system for remote inspection of a portable tank located in an installed position in a healthcare facility and adapted to store oxygen, the system comprising:

a first detector in communication with the oxygen tank for measurement of a level of oxygen stored in the oxygen tank;

a second detector configured to detect a location of the oxygen tank;

an electronic circuit in communication between the first and second detectors and a central station located remotely from the portable tank, the electronic circuit configured to issue a signal to the central station that includes information about the level of oxygen stored in the oxygen tank and the location of the oxygen tank; and

a database storing a floorplan for the healthcare facility, the location of the oxygen tank correlated to the floorplan, and the level of oxygen stored in the oxygen tank as received at the central station from the oxygen tank.

2. The system of claim 1 wherein the electronic circuit is adapted to issue a wireless signal to the central station.

3. The system of claim 1 wherein the electronic circuit is configured to issue a signal to the central station upon detection of a lack of presence of the oxygen tank from its installed position.

4. The system of claim 1 wherein the electronic circuit is configured to continuously issue a signal to a display device that includes information about the level of oxygen.

5. The system of claim 1 wherein the electronic circuit is configured to periodically issue a signal to a display device that includes information about the level of oxygen.

6. The system of claim 1 wherein the electronic circuit is configured to issue a signal to a display device upon detection of an oxygen level at or below a predetermined threshold.

7. The system of claim 1 further comprising a third detector configured to detect presence of an obstruction restricting access to the oxygen tank.

8. The system of claim 7 wherein the electronic circuit is configured to issue a signal that includes information about the presence of an obstruction restricting access to the oxygen tank.

9. The system of claim 8 wherein the electronic circuit is configured to issue the signal that includes information about the presence of an obstruction restricting access to the oxygen tank upon detection of an obstruction by the third detector.

10. A system for remote inspection of a pressurized oxygen tank in a healthcare facility comprising:

a first detector in communication with the oxygen tank for measure of a predetermined internal condition of the tank;

a second detector configured to detect a location of the oxygen tank;

an electronic circuit in communication between the first detector and a remote central station for issue of a wireless signal to the remote central station, the wireless signal including information about the predetermined internal condition; and

a docking station, wherein the first detector is electrically connected to the docking station and the electronic circuit is at least partially contained within the docking station; and

a database storing a floorplan for the healthcare facility, the location of the oxygen tank correlated to the floorplan, and the level of oxygen stored in the oxygen tank as received at the remote central station from the oxygen tank.

11. The system of claim 10 wherein the electronic circuit is adapted to issue a wireless signal upon detection of the predetermined internal condition.

12. The system of claim 10 wherein the predetermined internal condition comprises an out of range pressure condition of the oxygen.

13. The system of claim 12 wherein the detector comprises a fluid pressure gauge in communication with the oxygen for measure and display of a pressure condition of the oxygen.

14. The system of claim 10 wherein the electronic circuit is configured to issue a signal upon detection that the pressure of the oxygen is at or below a predetermined level.

15. The system of claim 10 wherein the electronic circuit is adapted to issue a signal upon detection of a lack of presence of the oxygen tank in an installed position.

16. The system of claim 10 further comprising:

a third detector for detection of a predetermined external condition.

17. The system of claim 16 wherein the third detector comprises a sonic sensor for detecting presence of an obstruction to or viewing of the oxygen tank.
