Based on the design and features, these three ventilators of ISRO have been named Prana, Vayu and Swast (PRANA, VaU, SVASTA). All three are fully automatic and touch-screen as well as meet all the safety standards.
After DRDO, now the Space Institute of the country has also come forward in the battle of Coronavirus Pandemic. During the second wave of Corona, the demand for ventilators and oxygen concentrators has increased in many states of the country and they are being imported from abroad. In such a situation, the Indian Space Research Organization (ISRO) has prepared three different types of ventilators at very low cost. Along with this, ISRO has also prepared a low-cost oxygen concentrator.
Based on the design and features, these three ventilators have been named Prana, Vayu and Swast (PRANA, VaU, SVASTA). All three are fully automatic and touch-screen as well as meet all the safety standards. The PRANA ventilator is meant to deliver inhaled gas to the patient through an AMBU bag (Artificial Manual Breathing Unit), Swast is designed to work without electricity and the VaU is a very low cost ventilator that is commercially available. Equivalent to ventilators available from
PRANA ventilator comprises of airway pressure sensor, flow sensor, oxygen sensor, servo actuator along with expiration and PEEP (Positive and Expiratory Pressure) control valves. This ventilator can deliver the required amount of oxygen to the lungs of the patients at the rate set by the doctors. In this, doctors can select the ventilation mode and set the required parameters through a touch screen panel and monitor different parameters like pressure, flow, volume and oxygen concentration on a single screen.
An external battery has also been installed in this ventilator for backup when the light goes off. ISRO said that the PRANA ventilator works on both invasive and non-invasive ventilation mode and is capable of giving controlled by ventilator as well as controlled by patient. Simultaneously, for safe ventilation of the patient, a robust algorithm has also been implemented in it which opens the safety valve by sounding an alarm to prevent barotrauma, asphyxia and apnea during ventilation. An alarm may also sound in case of incorrect or improper connection of ventilation circuits or disconnection of hose or sensor.
ISRO said that the ICU grade positive pressure mechanical ventilator VaU (Ventilation Assist Unit) can assist in breathing easily in patients under shortness of breath. This ventilator filters the air or oxygen and delivers it to the patient. The VaU ventilator also has a Human Machine Interface (HMI) system, which runs on a medical grade touch screen PC, allowing the operator to set and monitor individual ventilation parameters in real time.
This ventilator also features a power supply unit, which can operate at 230VAC or with an internal battery pack. The VaU is designed to be able to operate in different patient or ventilator trigger invasive and non-invasive ventilation modes and has HMI (Human Machine) to detect and alert the operator in case of any malfunction. The facility to sound the alarm through the interface) system has also been added.
According to ISRO, the gas-powered ventilator ‘Space Ventilator Aided System for Trauma Assistance (SVASTA)’ is designed to be used in emergency during pandemics to work under different ventilation conditions using manual mechanical settings. is enabled. The prototypes of these three ventilators made at the Vikram Sarabhai Space Center (VSSC) have been tested and all three meet different specifications.
Commercial production of these three ventilators (Commercial Production), for which interested industries or entrepreneurs have been invited to apply before June 15. Along with this, Vikram Sarabhai Space Center has also developed a medical oxygen concentrator which has been named ‘Shavas’. It has been said that it is capable of supplying 10 liters of oxygen per minute enough for two patients in a minute.
