Pressure injury is the most important issue facing paralysis patients and the elderly, especially in long-term care or nursing. A new interfacial pressure sensing system combined with a flexible textile-based pressure sensor array and a real-time readout system improved by the Kalman filter is proposed to monitor interfacial pressure progress in the cardiac operation. With the design of the Kalman filter and parameter optimization, noise immunity can be improved by approximately 72%. Additionally, cardiac operation patients were selected to test this developed system for the direct correlation between pressure injury and interfacial pressure for the first time. The pressure progress of the operation time was recorded and presented with the visible data by time- and 2-dimension-dependent characteristics. In the data for 47 cardiac operation patients, an extreme body mass index (BMI) and significantly increased pressure after 2 h are the top 2 factors associated with the occurrence of pressure injury. This methodology can be used to prevent high interfacial pressure in high-risk patients before and during operation. It can be suggested that this system, integrated with air mattresses, can improve the quality of care and reduce the burden of the workforce and medical cost, especially for pressure injury.
压力性损伤是瘫痪患者和老年人面临的最重要问题，尤其是在长期护理或护理中。提出了一种新的界面压力传感系统，该系统结合了柔性纺织基压力传感器阵列和经过卡尔曼滤波器改进的实时读数系统，用于监测心脏手术中的界面压力进展。通过设计卡尔曼滤波器和参数优化，可以将噪声免疫提高约 72%。此外，首次选择心脏手术患者来测试该开发系统，以确定压力性损伤与界面压力之间的直接相关性。记录了手术时间的压力进展，并通过时间和二维相关特性以可见数据呈现。在 47 名心脏手术患者的数据中，极高的体重指数（BMI）和 2 小时后显著增加的压力是与压力性损伤发生相关的前 2 个最重要因素。这种方法可用于在手术前和手术期间预防高风险患者的高界面压力。可以建议将该系统与气垫结合使用，可以提高护理质量，减轻劳动力和医疗费用的负担，特别是在压力性损伤方面。
