Defence Institute of Advanced Technology (DIAT) has developed 'Aashray', medical bed isolation system to combat COVID-19

Pune: Defence Institute of Advanced Technology (DIAT) has developed 'Aashray', medical bed isolation system to combat COVID-19 by stopping or minimising the spread of virus or infection released by the patient.

This is a low cost, reusable solution to maintain proper isolation of COVID-19 patients by creating a suction or negative pressure near exhale and further filtering and disinfecting the aerosol.

A statement from DIAT says, "Bed Isolation System envelopes are made up of specialized material and manufacturing process with transparent and translucent size (7.5 feet in length, 7 feet in width and 6.5 in height) supported on medical grade materials structure. The product is modular and portable in design and can be suitable for different requirements such as institutional, hospitals and home/ individual quarantine. The envelope is reusable as it is antibacterial-antifungal and can be sanitized. Each envelope is capable of housing one set of bed, table and chair along with some walking space. The width of the envelope can be adjusted as per the availability of space. The envelope is opaque up to 3 ft from bottom to maintain the privacy of the patient."

"The entire envelope is maintained at a low pressure (suction) with adjustable flow rate to restrain the spread of virus or infection inside the hall or ICU. Each envelope is connected to the main duct equipped with Ultraviolet (UV) light and filter circuit of Pre, fine and HEPA filter (recommended for medical application) and suction blower. The cross-flow of air from the top of the envelope towards the main duct is regulated (with a flap valve) as per the comfort conditions of the patient. The virus or contaminants are continuously sucked through the duct and accumulated at the filters which are projected with UV light. The suction blower throws the filtered and contamination-free air to the outside environment," DIAT has said.

As per prototype manufacturer, Cleancore Solutions based in Bhosari, the cost of the setup for a unit of 10 beds is one lakh rupees and for home-quarantine will be Rs 15,000 for a single bed, DIAT officials said.
