1. A portable oxygen generator system comprising:
a cartridge system comprising:
a container comprising a generator drawer operable in a lateral direction, wherein the generator drawer comprises at least four hollow chambers, wherein the at least four hollow chambers are separated by a pre-defined structure;
at least four cartridges housed within the corresponding at least four hollow chambers, wherein each of the at least four cartridges is configured to generate oxygen upon triggering a reaction of a pre-defined amount of water with one or more chemicals in a chemical chamber located within each of the at least four cartridges;
an accumulator operatively coupled to the at least four cartridges via a set of pipes and configured to receive and accumulate the generated oxygen;
a compressor operatively coupled to the accumulator, and configured to receive accumulated oxygen from the accumulator and compress received oxygen, thereby reduces space required to store the compressed oxygen;
at least one storage tank operatively coupled to the compressor, and configured to store the compressed oxygen received from the compressor;
an oxygen pressure regulator operatively coupled to the at least one storage tank, and configured to enable a uniform flow of oxygen at pre-defined oxygen pressure required for breathing at an output coupled to a patient to supply the oxygen from the at least one storage tank;
an oxygen flow control knob operatively coupled to the oxygen pressure regulator and the at least one storage tank, and configured to regulate flow ratio of the oxygen being supplied to the patient in an instant;
a humidifier means operatively coupled to the at least one storage tank, and configured to impart humidity to the oxygen being released from the at least one storage tank to the output coupled to the patient to supply the oxygen;
a pneumatic circuitry means sealed to the cartridge system, wherein the pneumatic circuitry means comprises an electronic control circuit configured to control an operation of the compressor;
a wheelbase attached to a bottom surface of one of the generator drawer or the pneumatic circuitry means to impart mobility of the portable oxygen generator system; and
wherein the portable oxygen generator system is configured to facilitate unidirectional flow of oxygen generated in the at least four cartridges via a plurality of valves to the humidifier means.
