Rajesh Ambwani IIT, an IIT Delhi Alumni, extremely dedicated personality has left no areas untouched with his designs and developments. From installing friction dampers, anderon meter, grinding spindle, loading system, roller feeder to designing and developing world-class turbine ventilators, he has manufactured many products to solve several problems. Among them is his contribution in developing turbine-based ventilators and that is praiseworthy.

Tooling around with technology is common among techies especially in IITians but Rajesh Ambwani pushed the mechanical button further. With his latest design of Turbine-based ventilator cum high-flow Nasal Cannula, he has come up with an alternative to traditional gas-based compressed ventilators.

Usually, it requires a long time for any manufacturer to develop a model from a basic idea, however, Mr Ambwani is among those who do not follow a traditional norm. During the critical time of the pandemic, where people are hopeless and distressed, Rajesh under the guidance of IIT Delhi started working on developing cost-effective turbine-based ventilators. This device has solved the major problem of Indian hospitals that is the lack of ventilators. It is a life-saving technology and helped a lot of Covid patients. Wondering how? Want to explore more? We understand your curiosity and hence Mr. Ambwani has shared a lot of details in this piece. Read on.

Ventilator and its demand | Rajesh Ambwani IIT

Ventilators are artificial breathing devices that provide oxygen to the lungs. It is used in a variety of breathing problems. Ventilators are often known by other names such as breathing machines, respirators, and mechanical ventilation. It is a powerful ally for patients who require serious medical care.

Rajesh Ambwani IIT, It has been believed by doctors all over the World that keeping a critically ill patient on a ventilator is really helpful to maintain the condition stable. The belief of doctors and their statements has increased the demand for this life-saving instrument worldwide. With the shortage of medical oxygen in the country, Rajesh Ambwani took it as a challenge and decided to develop a device that can provide support and help to the country’s healthcare sector. This demand for critical input gas components went on the peak when Covid-19 hit the world.

Turbine-based ventilators have proved as an effective alternative for manufacturers, medical professionals, and patients to run an efficient ventilator support system. According to the recent report, it has been mandated by the government that in Covid-19 cases a compressor or turbine-based ventilator should be used. During this severe situation, turbine-based ventilators are proved to be highly reliable, flexible, and robust.

Covid 19 and Ventilators

The major symptoms of Covid-19 include respiratory issues and this causes breathing-related problems and coughing in patients’ bodies. Ventilators are highly used to diagnose patients who are suffering from Covid-19 infection.

Among 7 types of known Coronaviruses that can affect humans, 3 can cause severe respiratory infections. These are –

• Severe Acute Respiratory Syndrome (SARS)
• Middle East Respiratory Syndrome (MERS)
• Coronavirus Disease 2019 (COVID-19)

The COVID-19 virus can enter the body through the nose, eyes, and mouth. Once the virus enters your body it starts affecting the lungs and when conditions become critical it starts lining your airways. To provide support to the lungs, a lifesaving device ventilator is used. This device assists with breathing by creating pressure in your lungs and thus providing the required oxygen to the sufferer.

The inflammation happened because the infection can disturb the ability of your lungs to clean debris and fluid. This deprives oxygen in your body. Turbine ventilators create pressure in your lungs and this helps with breathing.

Working of Turbine-Based Ventilators

Rajesh Ambwani IIT, The concept of turbine generator technology is employed to manufacture turbine-based ventilators. In this, the kinetic energy of major components such as combustion gases, water, the air is converted into electrical energy. The IIT alumnus Rajesh says that turbine ventilators are much better than other conventional ventilators as with the help of compressor turbine ventilators can generate enough gas flow for the patient to sustain.

A negative pressure is generated by a turbine that helps the filter to suck room air into the ventilator. Fresh oxygen gas is supplied to the circuit and then the turbine compresses the mixture of ambient air and fresh oxygen in order to generate a flow. The most important thing is, turbine ventilators are not dependent on any central gas supply infrastructure.

Features of Turbine-based Ventilators

As turbine ventilators are helping all the hospitals to maintain the stable condition of Covid-19 patients, it is crucial to explore its unique features.

• Turbine Ventilators are advanced in design thus are safe, reliable, and clinically tested for use as ICU ventilators.
• There is no need for compressed medical air
• It can be used for 8 hours and in multiple infrastructural setups
• It is well tested by doctors and has met all the specifications given by the Government of India.
• Turbine ventilators are versatile and can be worked either on a turbine or on an external source of compressed air.
• It comes with the intelligence to adapt to patient needs.
• Turbine-based ventilators are appropriate for providing non-invasive modes of ventilation

Turbine Ventilators are more than just a necessity

Rajesh Ambwani understood this need earlier and thus started working on developing turbine-driven ventilators. During this Covid-19 period, the shortage and increasing prices of oxygen made turbine ventilators more than a necessity. As there are no proper oxygen plants in remote areas, it becomes a cumbersome task to supply oxygen in these areas. With advanced turbine-based ventilators, this task becomes easier because these ventilators require less oxygen at low pressure for the patient to remain in stable condition.
