Scarless operations via ‘spider tech’

New Delhi, Apr 5: Joining efforts to fight COVID-19, the Defence Research and Development Organisation (DRDO) has designed a full-body disinfection chamber and a special face protection mask for healthcare professionals, officials said.

The special chamber called 'PSE' has been designed by Vehicle Research Development Establishment (VRDE), Ahmednagar, a DRDO Laboratory.

The walk through enclosure is designed for personnel decontamination, one person at a time. It is a portable system equipped with sanitiser and soap dispenser, officials said.

The decontamination is started using a foot pedal at the entry. On entering the chamber, electrically-operated pump creates a disinfectant mist of hypo sodium chloride for disinfecting, the DRDO said in a statement.

The mist spray is calibrated for an operation of 25 seconds and stops automatically indicating completion of operation. As per procedure, personnel undergoing disinfection will need to keep their eyes closed while inside the chamber, it said.

The system consists of roof mounted and bottom tanks with a total of 700 litres capacity. Approximately 650 personnel can pass through the chamber for disinfection until the refill is required, the DRDO said.

The system has see-through glass panels on side walls for monitoring purpose and is fitted with lights for illumination during night-time operations, it added.

This system can be used for disinfection of personnel at the areas of controlled ingress and egress such as entry and exit to hospitals, malls, office buildings and critical installations, officials said.

Also, Research Centre Imarat (RCI), Hyderabad, and Terminal Ballistics Research Laboratory (TBRL), Chandigarh, have developed face protection mask for healthcare professionals handling COVID-19 patients, the DRDO added.

Its light weight construction makes it convenient for comfortable wear for long duration. This design uses commonly available A4 size Over-Head Projection (OHP) film for face protection, it said.

One thousand face shields are being produced daily in TBRL and provided to Postgraduate Institute of Medical Education and Research (PGIMER), Chandigarh, it said.

Similarly, 100 are produced at RCI and these have been handed over to Employees' State Insurance Corporation (ESIC), Hyderabad. A demand of 10,000 shields has been received from PGIMER and ESIC hospitals based on successful user trials, the DRDO added.

New Delhi, Mar 25: The Congress said on Wednesday that it stood with Prime Minister Narendra Modi on his appeal for 21-day lockdown but was "deeply disappointed by the lack of coherent strategy" and demanded that Rs 7,500 should be transferred to every Jan Dhan, PM Kisan and pension account to tide over the nutrition needs for 21-days.
It also demanded that the Public Distribution System (PDS) ration should be given free.
In a series of tweets, Congress Communications in-charge Randeep Singh Surejwala said that the need of the hour was to implement 'Minimum Income Guarantee Scheme' (Nyay) mooted by the Congress and party leader Rahul Gandhi.
"Please transfer Rs 7,500 to every Jan Dhan, PM Kisan, and every pension account to tide over nutrition needs of 21 days and give free PDS ration. We will rise together as a nation and defeat COVID-19. We stand with lockdown but are deeply disappointed by the lack of coherent strategy or a clear 'way ahead' on your part," he said.
Surjewala asked what steps the government took despite an early warning about COVID-19 and sought details about isolation beds and ventilators available to people.
"Dear PM, India will adhere to the lockdown but what steps did the govt take to tackle the corona pandemic despite early warnings in Feb? When will doctors, nurses and health workers have adequate protection? How many 'isolation beds' and ventilators are available and where?" he said.
He asked how daily wagers and labourers will sustain during the 21-day lockdown.
"What's your plan to address the huge issue of bread and butter and livelihood for millions? How will daily wagers, labourers, MGNREGA workers, factory workers, unorganised workers, fishermen, farmers and farm labour sustain for 21 days?" he asked.
Surjewala said the crying need is to arm doctors, nurses and health workers with personal protection equipment and asked: "why are N-95 masks, Hazmat suits not available?"
"In March itself, India needs 7.25 lakh bodysuits, 60 lakh N-95 masks, 1 crore 3 ply masks? When will they be available?" he asked.
Surjewala said that the government banned the export of ventilators, respiratory devices and sanitisers only yesterday on March 24, "84 days after the spread of COVID-19."
"Is this your government's 'Modus operandi' to fight coronavirus? Too little, Too late!," he said.
Noting that two-thirds of the country's population is engaged in agriculture, he said that Prime Minister Modi did not refer to farmers during his address to the nation and demanded a moratorium on farmers' loans.
"Crop is ready for harvest in March itself. How will it be harvested and sold and who will buy at fair price? Indebtedness relief to farmers is the only way forward in these testing times. Please put a moratorium on farmers' loans and recoveries. Please ensure the procurement of crops at MSP. Let's not forget that farmers are the backbone of India's economy," he said.
Surjewala said the Prime Minister gave only four hours to prepare for 21-day lockdown.
"Did you think of over 5 lakh truck drivers, who are now stranded on roads? Did you think of millions of workers, who are stranded in cities away from home without food or money? What should they do," he asked.
