The study was to compare an off-loading cushion, designed for individuals with spinal cord injury, with air cushion to analyze the effect of pressure on skin injury and user satisfaction. The off-loading cushion can reduce the incidence of pressure ulcers by minimizing the pressure of the ischial tuberosity and coccyx. Because anatomical structures of each participant are different, 3D scanning is used in the customized manufacturing of the cushions. In the 3D modeling, the product is designed so that the ischial tuberosity and coccyx have minimal contact with the cushion’s surface area. The X-sensor was used to confirm the pressure dispersion effect. As a result, maximum pressure of the ischial tuberosity and the coccyx were measured and observed to be lower than that of the air cushion. User satisfaction was compared between two cushions using the QUEST 2.0. The off-loading cushion has slightly higher service and product satisfaction than the air cushion. Based on these findings, this study suggests that off-loading cushions reduce the occurrence of pressure injury compared to air cushions.

基于3D建模的定制卸载气垫的压力分布效果及用户满意度研究：与传统气垫的对比

该研究旨在比较专为脊髓损伤患者设计的卸载缓冲垫与气垫，以分析压力对皮肤损伤和用户满意度的影响。卸载垫可以通过最大限度地减少坐骨结节和尾骨的压力来减少压疮的发生。由于每个参与者的解剖结构不同，因此在坐垫的定制制造中使用了 3D 扫描。在 3D 建模中，产品的设计使得坐骨结节和尾骨与坐垫表面区域的接触最小。X传感器用于确认压力分散效果。结果，测量坐骨结节和尾骨的最大压力并观察到低于气垫的压力。使用 QUEST 2.0 比较了两个坐垫的用户满意度。卸货垫的服务和产品满意度略高于气垫。基于这些发现，本研究表明，与气垫相比，卸载垫可减少压力损伤的发生。
