본 연구에서는 의료 종사자가 고위험성 감염환자(의심)를 진료할 때 발생할 수 있는 공기중 감염균의 전파를 방지하고 안전한 의료 환경을 보장하기 위해 의료용 국부환기정화장치를 개발하는데 필요한 실험적 벤치마킹을 수행하였다. 이를 위해 국내외 의료현장에서 사용되고 있는 국부환기정화장치의 사례와 기술현황을 조사하였으며, 산업 후드형 국소배기장치를 활용하여 의료 종사자의 진료 상황을 모사한 실험을 통해 입자제거효율과 추적가스 농도저감 성능을 평가하였다. |

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. |
