Oxygen concentrator remote monitoring apparatus
First Claim
1. A monitoring apparatus for remotely monitoring the operational status of an oxygen concentrator having a plurality of diagnostic light emitting diodes wherein said light emitting diodes indicate the operational status of said oxygen concentrator comprising:
- a hollow boot having an opened end for forceably fitting over said light emitting diode;
a photodetector mounted within said boot for detecting light emitted from said light emitting diode;
means responsive to said photodetector for determining the operational status of said oxygen concentrator;
a computer responsive to said determining means for receiving said operational status of said oxygen concentrator.

Abstract
The invention provides an inexpensive and electrically isolated remote monitoring apparatus for monitoring the operational status of any oxygen concentrator by specifically monitoring the standard set of high and low pressure diagnostic light emitting diodes provided with most concentrators. Flexible boots enclose the respective optodetectors and are forceably pushed over the diagnostic diodes of the oxygen concentrator so that any light emitted by either diode is detected by the respective optodetector. The optodetectors are further connected to a microcontroller. A telephone line interface port connects to the microcontroller and provides for a telephonic communication link between the microcontroller and a remote computer. When a malfunction is detected and analyzed by the microcontroller, both the type of malfunction and a location code is transmitted to the remote computer.
