응급의료 동작을 반영한 개인보호복 개발

Abstract

This study aims to develop and evaluate personal protective equipment (PPE) optimized for Korean emergency medical service (EMS) providers. We began by measuring dimensional changes across different body parts during various emergency medical procedures, using this data to determine the ease allowance necessary for pattern design. Specifically, we conducted a comparative analysis of changes in the length of body surface reference lines during movements such as bending the knees, sitting, and lying prone, all relative to an upright posture. Notably, the line connecting the iliocristale, midpatella, and lateral malleolus exhibited the most significant change in length. This area was identified as critical for ensuring mobility in PPE design, as it is where highly mobile actions frequently occur due to the nature of EMS activities. Based on these findings, we evaluated the functional and aesthetic fit of the PPE produced using the designed pattern and compared it with existing commercial PPE. The functional suitability of the new PPE was confirmed, as the prescribed donning and doffing procedures were smooth and efficient. Results indicated that the developed PPE received higher evaluations for its improved fit and comfort during medical activities. In particular, this demonstrates that a pattern with an enhanced design in the posterior body region—often cited by participants as a source of discomfort during experiments—was successfully developed.
