Researchers from the Department of Biomedical Engineering of Bangladesh University of Engineering and Technology (BUET) have invented a low-cost C-PAP ventilator device called ‘OXYJET’ – which will meet the need for oxygen for patients with Covid-19 and other respiratory diseases.
The researchers are – Meemnur Rashid, Kawsar Ahmed and Farhan Muhib, research assistants at BUET’s Department of Biomedical Engineering, department lecturers Kaiser Ahmed and Saidur Rahman. Dr. Tawfiq Hasan, Assistant Professor of the department, is under overall supervision.
About the project, Meemnur Rashid said the oxygen demand has increased in all the hospitals amid the COVID situation. ICU crisis and power problems are on the rise. In such cases, ‘OXYJET’ will play a helpful role for the patients. “This device does not require an electrical connection. It cost only Tk 2000.”
“High-flow oxygen can be supplied from the cylinder or the hospital supply line. This could be an alternative to the High Flow Nasal Canola (HFNC),” he added.
Kawsar Ahmed, another researcher of the project, said the device would store natural oxygen from the air. This creates the capacity to supply about 60 liters of oxygen, combining natural oxygen with cylinder oxygen. This high-flow oxygen is given to the patient through a CPAP mask.
“The mask is made in such a way that there is no possibility of leakage. As a result, the patient can easily overcome the oxygen shortage, can breathe comfortably.”
Kawsar Ahmed added the ‘OXYJET’ in ambulances will be able to provide healthcare in remote areas and on the way. On the other hand, high-flow oxygen is required when the condition of COVID sufferers deteriorates. “Such devices include HFNC can be used outside the ICU. However, it is quite expensive.”
Kaiser Ahmed, a lecturer at the Department of Biomedical Engineering, said that a thin venturi creates a combination of air and oxygen through a valve and delivers it at a speed of at least 60 liters/minute. Medical oxygen supply and dual flow meters can give up to 100% oxygen concentration if required. ‘OXYJET’ will be able to provide high-speed oxygen services to patients in the general ward. So, the “pressure of patient admission in ICU will be reduced”.
He added that using the device in an oxygen cylinder would “increase the patient’s oxygen saturation by about 12 percent” – which can be very comforting for the patient. “‘OXYJET’ has been used on Covid-19 patients at Dhaka Medical College Hospital for some time,” said Kaiser Ahmed.
Dhaka Medical College Hospital (DMCH) medicine specialist Dr. Farhad Uddin Hasan Chowdhury said if “COVID takes a more terrible shape” then it will be needed all over the country. This device can be the light of hope. Then we will be able to save many serious patients. Moreover, the role of this machine in “overcoming the problem of ICU is undeniable”.
Dr. Tawfiq Hasan, Assistant Professor of the Department of Biomedical Engineering of BUET, said 50 more “OXYJET CPAP” were being made on an emergency basis.
If initial success is found in the third phase of the trial, the trial is being planned on a larger scale in other hospitals, subject to the approval of the Bangladesh Medical Research Council (BMRC) and with the assistance of the Directorate General of Health Services (DGHS). Then it can deliver to other hospitals, he added.
