Researchers at Durgapur-based Central Mechanical Engineering Research Institute (CMERI) has indigenously developed a ventilator amid rising cases of COVID-19.

The bellow design, controllers and embedded electronics of this ventilator have all been customised to ensure price efficacy as well as meeting the requirements of the relevant industries.

According to researchers, this ventilator has a closed loop monitoring system, which can sense patient breathing effort. If present, it will assist the patient in breathing and in its absence, it will allow the prescribed amount of tidal volume into the patient lungs. This version is primarily intended to be used in small clinics, medical colleges, nursing homes, isolation wards etc., where pressurised medical air and oxygen supply pipelines are absent.

The automated portable mechanical ventilators might be deployed to help huge volumes of prospective patients, if required.

The prototype has been equipped with multiple life-saving control features such as Tidal Volume, Breaths per Minute and Inspiratory/Expiratory ratios. Keeping in the mind the probable mass requirement of this Life-Saving medical equipment, portability and cost effectiveness are two of the most primary elements of the product. These mechanical ventilators are equipped with the latest technologies which can easily out-compete other available Ventilators in the market.

“The ventilator has undergone multiple technical and design changes after adopting critical feedbacks from healthcare professionals of the Health World Hospital and Vivekananda Hospital, Durgapur. This ventilator will be further upgraded to meet the requirements of various other patient’s parameters”, said Prof. Harish Hirani, Director of CSIR-CMERI.

He added, “The efficacy of a ventilator for a patient is also correlated to the effective response of the attending healthcare personnel. Steadily, the approach of this Institute will be to harness artificial intelligence capabilities to automate the functioning of mechanical ventilators, so that the ventilators automatically respond to the fluctuating variables of a patient.”

Since the individual parts of the ventilator can be independently developed by different industries, mass-development of this ventilator will help a broad spectrum of industries. The significantly reduced cost of the ventilators will help the economically marginalised sections of the society the most as well as help further fortify the Government-aided healthcare schemes. This will also help in upgrading the tertiary healthcare infrastructure.

“We are in conversation with several industries for quick commercialisation of this newly developed ventilator to ensure availability of these ventilators in makeshift hospitals, basic hospitals, and other healthcare facilities”, said Prof. Hirani. (India Science Wire)
