Hungarian researchers develop a mass ventilator that can combat Covid-19
By World Healthcare Journal-
A team of research and development engineers, doctors and mathematicians have created the MassVentil system, a ventilator that is able to ventilate up to 5 people at the same time. It is currently being enhanced to ventilate up to 50 people simultaneously– all while protecting healthcare workers.
With the advent of the Covid-19 pandemic, a lack of ventilators was a major problem that many hospitals faced with the sheer abundance and influx of patients suffering from the virus. To make matters worse, the ventilators that were available could only support one person at a time. A key symptom of the virus was acute respiratory problems within the human body, and hospitals were struggling to keep up with the demand of patients needing a ventilator to support their breathing.
Dr. Miklós Kozlovszky, Associate Professor at Obuda University in Budapest, assembled a team of researchers to invent a machine that would help patients suffering with the pandemic to breathe better, as well as shield healthcare workers from possible contraction of the virus.
With its revolutionary concept and design the MassVentil project could help the medical community fight the ongoing threat of coronavirus. As a research and development engineer, as well as head of the MassVentil project, Dr. Kozlovszky stresses that the ventilators’ ability to protect healthcare workers is one of its greatest advantages, as the exhaled air from patients is filtered and removed from the surrounding areas.
The ventilator is designed to be stand-alone - it does not need to be connected to hospital infrastructure for gas and electric supply. This mobility allows the ventilator to be utilised in places that do not have a complete hospital structure.
“The system consists of two main parts: a central gas transport system and smaller patient-specific ventilators. The central inhalation and exhalation gas management allows more patients to be ventilated at the same time, thereby saving more lives,” says Dr. Kozlovszky.
The individual patients’ breathing modules can be connected modularly to the intake air duct system and the exhalation duct system. Each breathing module comprises a controllable oxygen blender and a controllable three-passage valve as well as software for individually controlling the breathing parameters of the patient(such as respiration count, volume, pressure, oxygen concentration.
Early prototypes of the ventilator were designed using 3D printers. "With 3D printers we reached the prototype phase quicker and at a lower cost than planned, printing, installing and testing within a couple of hours. The licensing process is still underway, but the tests are encouraging," he adds.
