摘要
床垫材料对人体腰臀部的支撑是影响睡眠健康的关键因素。研究了床垫软硬度和腰臀区域床垫填充材料对不同臀围人群仰卧时腰骶椎矢状面形态的影响。首先对36名实验对象进行了身体尺寸和站姿腰骶椎脊柱点位距离测量。其次,使用自主研发的卧姿腰骶椎矢状面形态测量装置,测试分析了3类实验对象(臀围≤90 cm、90 cm<臀围≤100 cm、臀围>100 cm,n=12)分别仰卧于9款具有不同软硬度(软、中、硬)与不同腰臀区域床垫填充材料[无、多功能热塑性聚酯氨弹性体(MTPU)、乳胶]的实验床垫上时腰臀部(T12、L4、S5)的下陷量。结果表明:床垫软硬度和腰臀区域填充材料交互项对仰卧时人体腰臀部下陷量和腰臀间隙值均影响显著,当人体仰卧于“软-乳胶”床垫组合上时,臀部最凸点(S5)下陷量、腰臀间隙值最大,此时人体站-卧姿腰臀间隙值吻合度最高。臀围对仰卧时人体腰臀部下陷量和腰臀间隙值影响显著,其中,臀围越大,仰卧时腰臀部下陷量越大。不同臀围人群与床垫的匹配结果显示,3类人群与“软-乳胶”床垫组合适配性最高,且该床垫组合对中臀围人群腰骶椎的支撑效果最好,小臀围人群次之。
The support provided by mattress materials for the waist and buttocks of the human body is a key factor affecting sleep health.This study examined the effects of mattress firmness and filling materials in the lumbar and hip regions on the sagittal morphology of the lumbosacral vertebrae in supine individuals with varying hip sizes.Firstly,the body sizes and standing position distances of the lumbar sacral spines of 36 experimental subjects were measured.Secondly,using a self-developed device for measuring the sagittal morphology of the lumbar and sacral vertebrae in a supine position,three types of experimental subjects(hip circumference≤90 cm,90 cm<hip circumference≤100 cm,hip circumference>100 cm,n=12)were tested and analyzed for their lumbar and buttocks(T12,L4,S5)when lying on nine experimental mattresses with different firmness(soft,medium,hard)and different filling materials[no,multifunctional thermoplastic polyester polyurethane(MTPU),latex].The results showed that the interaction between the softness and hardness of the mattress and the filling material in the waist and buttocks area had a significant impact on the amount of waist and buttocks subsidence and the value of waist and buttocks clearance when lying on the back.When the human body was lying on the“soft latex”mattress combination,the most protruding point of the buttocks(S5)subsidence and the value of waist and buttocks clearance were the highest.Currently,the waist and buttocks clearance value in the standing and lying position of the human body was the most consistent.Hip circumference had a significant impact on the amount of waist and hip subsidence and the value of waist hip gap when lying on the back.Among them,the larger the hip circumference,the greater the amount of waist and hip subsidence when lying on the back.The matching results between different hip circumference groups and mattresses showed that the three groups of people have the highest compatibility with the“soft latex”mattress combination,and this mattress combination had the best support effect on the lumbar and sacral vertebrae in the middle hip circumference group,followed by the small hip circumference group.
