Depiction of multipurpose portable negative air flow protection chamber. (a) CAD drawing of a PVC tube frame of 60×60×60 cm. (A) 3D-printed hooks on the central bar for hanging equipment. (B) Stabilising tube can be added or removed in different lengths depending on the clinical circumstances. (C) Multiple 3D-printed suction/oxygen/nebuliser ports can be snapped on any of the supporting tubes to accommodate the physical location of these sources according to individual needs. CAD, computer-aided design; PVC, polyvinyl chloride. (b) The mannequin, resuscitation bag (on a hook), videolaryngoscope, tracheal tube, tape, and collection bag for contaminated equipment are shown inside the enclosed environment of the PVC frame draped with a clear plastic bag. Suction and oxygen supply are connected to the snap ports. (c) Fluorescein solution aerosolisation was created within the proposed chamber using the ultrasound nebuliser. With the help of ultraviolet light, visualisation of aerosol/droplet effective containment, and continuous negative airflow through the suction tubing in the upper left corner, was successfully achieved.
