Sylhet’s four ‘wonder youngsters’ have created turbine-based open source ventilators using fully indigenous technology, thinking of critically ill patients infected with the global pandemic coronavirus. Two of the four youths are former students of Shahjalal University of Science and Technology (SHU) and two others are former students of Sylhet Metropolitan University (MU). They have a team called Crax.Syed Rezwanul Haque Nabil, a former student in the physics department at Shahjalal University of Science and Technology (SUSTU) and CRACS team leader, said they could be commercially produced and marketed in a short time with government support. Over the past four months or so, they have developed this ventilator, keeping in mind the critical patients with coronavirus. The ventilators they make are easily portable and require less electricity to run. For this reason it can also be used in ambulances.Patients will not have any difficulty as the sound of the ventilator is low. An app has been used in it. The ventilator is controlled through these apps and various parameters of the ventilator can be seen.”The medical ventilator we made is turbine based,” Nabil said of their invention. Inside is a turbine that generates positive pressure. The hardware and software of this ventilator is made in its own technology. All we have done is open source. As a result, anyone can see its technology and work with it.He said that this ventilator supports PRVC, SIMV, PCV modes. The device’s GUI software is built on the Android platform which inputs and displays its various parameters. Its screen is 6 inches. As a result it contains sufficient amount of data such as pressure, air flow, volume, BPM, Ti etc. graphically and numerically.
