Pressure ulcers are a significant concern in patient care, particularly for those with limited mobility and extended hospital stays. Wavy mattresses are shown an effective tool for preventing or promoting the healing of these wounds by preventing pressure localization in different body regions. The current study aimed to present a novel double-layered wavy mattress design for the prevention and recovery of pressure ulcers, addressing some of the limitations of existing mattresses. The novel mattress includes double-layered cells, with the upper and lower layers, filled with water and air, respectively. The temperature of water in the cells can be manually adjusted to meet patients' needs, prevent skin sweating, regulate body temperature, and promote blood flow in areas susceptible to pressure ulcers. Patients who used this novel mattress during their hospitalization experienced a significantly shorter recovery period for bedsores compared to those who used other mattresses, showing that the novel wavy mattress is an effective tool for preventing and recovering from pressure ulcers in long-term hospitalized patients with limited mobility.
压疮是患者护理中的一个重要问题，对于那些行动不便且住院时间较长的患者来说尤其如此。波浪形床垫被证明是一种有效的工具，通过防止身体不同部位的压力集中来预防或促进这些伤口的愈合。当前的研究旨在提出一种新颖的双层波浪形床垫设计，用于预防和恢复压疮，解决现有床垫的一些局限性。这种新颖的床垫包括双层单元格，上层和下层分别填充水和空气。单元格中的水温可以手动调节，以满足患者的需求，防止皮肤出汗，调节体温，并促进易发生压疮部位的血液循环。与使用其他床垫的患者相比，住院期间使用这种新颖床垫的患者褥疮恢复期明显更短，这表明这种新颖的波浪形床垫是帮助行动不便的长期住院患者预防压疮和从压疮中恢复的有效工具。
