[Development and application of a mobile positive pressure clean chamber].

ABSTRACT

During the epidemic of coronavirus disease 2019, due to the need to collect a large number of nucleic acid samples, the staff are under great pressure. For this reason, the medical staff of China-Japan Friendship Hospital developed a mobile positive pressure clean chamber and applied for a national utility model patent (application number 202021173605.8). The equipment is composed of a cabin body, an operation hole equipped with rubber gloves, an interactive channel with two electric doors, an environmental control unitandanair-conditioner. When in use, the medical staff are located inside the cabin, and their hands are protruded by two operating holes to calculate and sample for the tested personnel. Then the samples are placed on the table outside the cabin waiting for inspection. The clean chamber can be used in hospitals, communities and other places, while achieving the goal of efficient sampling, and the risk of infection in the process is reduced by effectively blocking the contact between medical staff and the source of infection.
