New Delhi, July 21: In the first-of-kind innovation, the Indian Institute of Technology, developed an Oxygen Rationing Device called AMLEX that reduces oxygen wastage by regulating the flow of oxygen during inhalation and exhalation.

According to the statement, it supplies a required volume of oxygen to the patient during inhalation and trips when the patient exhales carbon dioxide. This process saves oxygen which otherwise unnecessarily gets wasted.
During exhalation, the oxygen in the oxygen cylinder or the pipe is also pushed out by the user along with the exhaled CO2. This leads to a large volume of oxygen wastage. Also, as there is a continuous flow of oxygen in the mask a large volume of oxygen escapes from the openings during the period between inhalation and exhalation.
AMLEX is a system developed specifically for oxygen cylinders. It synchronizes the flow of oxygen with the inhalation and exhalation of a patient.
The device can be easily connected between the oxygen supply line and the mask worn by a patient. It uses a sensor that senses and successfully detects inhalation and exhalation of the user in any environmental condition. The ministry in the statement said that it will increase the lifespan of an oxygen cylinder thus saving a lot of money for patients as well as hospitals.
Director, IIT, Ropar, Prof. Rajeev Ahuja informed that the AMLEX can operate on both portable power supply (battery) as well as line supply (220V-50Hz).
It has been developed by Ph.D. students of the Biomedical Engineering Department of the institution - Mohit Kumar, Ravinder Kumar, and Amanpreet Chander under the guidance of Dr. Ashish Sahani, Assistant Professor, Department of Biomedical Engineering. They developed this device after looking the demand of medical oxygen during the second wave of covid.
The innovators of AMLEX have said that they hope the device created by them will help in saving and reducing the wastage of oxygen and helps the patients as well as the hospitals in the long run.
