Introduction: Human corona virus infection disease (COVID-19) has resulted in a global pandemic affecting millions of people. The maximum risk of spread of infection is during transport of these infected patients within hospital or to a hospital.

Materials and Methods: An idea of combining negative and positive pressure systems to devise a portable batteryoperated, vacuum chamber for transport of infected and non-infected patients was adapted in devising a transport chamber. The chamber was used for transport of COVID patients as trial run following which swabs were taken from inlet and outlet to rule out virus contamination of the chamber. The relatives accompanying the patient and healthcare workers (HCWs) involved were also tested for corona virus.

Results: The pressurized protective transport chamber (PPTC) was used in transport of 152 COVID patients in trial phase and 556 patients in total. The swabs taken from outlet and inlet of PPTC showed no viral contamination. Also 200 HCWs and 250 relatives were tested and all were negative for COVID infection.

Conclusion: PPTC is an effective method of transport of infected patients and will help in curtailing the spread of infection.
