The Pune-based Defence Institute of Advanced Technology, (DIAT) a “deemed-to-be” University, Pune has developed a low cost reusable Medical Bed Isolation System to combat COVID-19 by stopping or minimizing the spread of virus/ infection released by the patient.
“This (Aashray) is a low cost, reusable solution to maintain proper isolation of Covid-19 patients by creating suction /negative pressure near exhale, and further filtering and disinfecting the aerosol,” a Pune-based defence spokesperson said.
Bed Isolation System envelopes are made up of specialized material and manufacturing process with each transparent and translucent envelope measuring 7.5 feet in length, seven feet in width and 6.5 ft 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.
“Apart from serving as a bed, 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. Envelope is opaque up to 3 ft from bottom to maintain privacy of the patient,” the spokesperson said.
The entire envelope is maintained at a low pressure (suction) with adjustable flow rate to restrain spread of virus/ infection inside the hall/ ICU.
“Each envelope is connected to the main duct equipped with UV light and filter circuit of Pre, fine and HEPA filter (recommended for medical application) and suction blower. The cross flow of air from top of the envelope towards the main duct is regulated (with a flap valve) as per the comfort conditions of the patient,” the spokesperson said.
“The virus / 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.” the spokesperson said
As per prototype manufacturer (M/s Cleancore Solutions Pvt Ltd. Bhosari, Pune), the cost of the setup for a unit of 10 beds is Rs 1 Lakh approximately and for home quarantine will be 15,000 (approx) for a single bed.
