This study aims to establish criteria for designing medical local ventilation purifiers, enhancing safety for healthcare workers treating suspected, high-risk infectious patients by preventing the spread of airborne infectious bacteria. To achieve this, there were cases and technological trends investigated of local ventilation purifiers used in medical settings both domestically and internationally. Experiments that simulated real medical treatment scenarios for healthcare workers were conducted using an industrial hooded local exhaust device. These experiments assessed the device"s ability to remove particles and trace gases. According to the SPS-KACA002-132 standard, in strong wind operation mode, the device achieved a particle removal capacity of 55.2 % for (0.3±0.1) um-sized particles and 54 % for (0.5±0.1)um-sized particles. The airflow velocity of the hooded local exhaust system varied with the installation angle, with the highest central air velocity (0.71 m/s) observed at a 45° installation angle, corresponding to the range of (0.5 ~ 1.0) m/s based on the second stage of ASHRAE industrial exhaust hoods (a total of 4 stages). The trace gas removal performance was optimal at the 45° installation angle. It"s worth noting that the performance of the local ventilation purification device was evaluated using the spatial unit evaluation method. However, this method has limitations as it primarily considers local effects. In future studies, additional factors such as noise and vibration should be considered.
