Those infected with respiratory infectious diseases carry a large number of highly pathogenic respiratory microorganisms, and are moving sources of infection. The Corona virus is spreading rapidly by touch, breath etc. We are proposing a powered wheelchair with negative pressure isolation hood, to transport the covid 19 patients with teleoperation control. COVID patients often need to travel from the isolation ward to various labs for blood tests, x-ray etc. This wheelchair can transport COVID patients within hospitals avoiding causing infection to others. The patients can be seated on the wheelchair covered by the negative pressure isolation hood and the operator/caretaker can use the teleoperation control method and operate the wheelchair from a safe distance of upto 4 meters without the need to touch the wheelchair. The negative pressure isolation hood using a Hepa filter will be developed and integrated to this powered wheelchair. In addition to app based control using a smartphone, a wireless joystick can also be used. In this way, the operator/caretaker can avoid direct contact with patients or wheelchair. The negative pressure isolation not only prevents the spread of pathogenic microorganisms, but also permits rapid and flexible isolation transport. The isolation hood must be airtight. The air discharged from ventilation is through standard medical grade filters and must be purified to ensure no harmful pathogens are spreading out.
