In the battle against the crown, doctors turn to low-cost, innovative ventilators.
NEW DELHI/NAGPUR: With the country concerned about shortages, some innovative options are emerging. Dr. Deepak Agrawal, professor of neurosurgery at, and Diwakar Vaish, a robotics scientist, who previously developed what they claimed was the world's cheapest ventilator, 'AgVa', costing around 1.5 lakh Rs, TOI was told they have improved this fan by incorporating a fan. Patent pending negative ion generator that inactivates the virus.
At Nagpur New Era Hospital, doctors have developed a tool with which eight patients can receive a ventilator at the same time. Although the fan dividers are not new, this is said to be the first to serve eight patients at once.
The health ministry in a statement said on March 30 that they had placed an order with 1,000 fans. Supplies are expected to start in the second week of April, he added.
The inactivated virus is trapped at the expiratory end by a positively charged system that protects the environment, said Dr. Agrawal, who called his device AgVa COVID.
The company received orders from more than 50,000 fans worldwide that it had to cancel due to the government's sudden export ban on fans, the sources said.
Now it is channeling its resources to meet the needs of central and different state governments.
The government has also placed an order for 30,000 fans, of which it will collaborate with national manufacturers in this effort. Indian automakers are also preparing to make fans, the government said. The Ministry of External Affairs is also reaching out to suppliers in China to get 10,000 fans from them.
Ventilators are required for Covid-19 patients as they tend to develop acute respiratory disease syndrome (ARDS). Currently, fewer than 20 have ventilation assistance, according to the health ministry. Faced with this, more than 14,000 ventilators have been identified in various hospitals across the country for the treatment of patients with Covid-19, says the ministry.
However, experts say the need for fans can increase exponentially. Two days ago, we created this divider with the use of a computerized 3D printing mechanism. Now, in an emergency like a mass casualty, we can ventilate eight patients with a ventilator. We can make more dividers of this type, if necessary, ”said Dr. Anand Sancheti, director of New Era Hospital.
Dr. Sancheti stated that Samir and Siddharth Bhusari of Saras Life Solution Company in Butibori provided valuable technical support for this invention.
The pulmonologist Dr. Sameer Arbat has designed a safe to perform difficult bronchoscopic procedures in patients with suspected or confirmed Covid-19.
Covid-19 spreads by coughing and sneezing, making it very risky to perform bronchoscopy procedures in suspected or confirmed Covid-19 patients. Aerosols generated by a patient during such procedures can infect the physician and spread in the surrounding area, thereby infecting other patients, ”said Dr. Arbat.
He worked on this design during closing and only used acrylic sheets and plastic materials available in the hospital since all vendors were closed. According to him, the prototype model has already been used and any doctor or hospital can easily replicate it to treat patients with Covid-19.
Dr. Arbat said he had the idea for some similar designs used by doctors abroad. “I did an improvisation to make the box multipurpose to perform bronchoscopies and intubation procedures. I think it is very economical to manufacture and should be useful for all doctors. It is advisable that doctors and staff wear the appropriate (PPE) for maximum safety, he said.
The nurses at the Meditrina Institute of Medical Sciences made innovative use of the available material to design a personal protective kit to cope with the shortage of PPE kits and masks. Necessity is the mother of invention. Our staff designed and sewed PPE kits right here at our hospital. I appreciate your effort. I know this is a makeshift fix. Physicians must obtain adequate protection as cases increase, ”said Dr. Sameer Paltewar, director of the Meditrina Institute. >
