    • A multisection composite material (10) useful in forming compression braces for orthopedic support of a body part includes a user contacting fabric section (12), an outermost fabric section (18) formed from bonding two dissimilar fabrics and an intermediate section (20) formed from a closed cell foam. The user contacting fabric section (12) is a fabric having multidimensional stretch properties formed from hydrophobic fibers and bonded to a surface (22) of the intermediate foam section (26). The outermost section includes a first fabric layer (18) having multidimensional stretch properties formed from hydrophilic fibers and a second fabric layer (16) having multidimensional stretch properties formed from hydrophobic fibers. The intermediate foam section (26) has a first surface and a second surface (22,24) and has a multiplicity of perforations (28) therethrough from the first surface to the second surface. The foam has multidimensional elastic properties sufficient for providing compressive strain useful for supporting the body part. The first layer (16) of the outermost section is bonded to the second surface (24) of the intermediate section (20). Moisture emitted from a user's skin passes through the hydrophobic user contacting section (12) to the intermediate section (20) whereupon it passes through the perforations (28) and is spread by the hydrophilic first fabric layer (16). The spreading of the emitted moisture by the hydrophilic layer (16) increases the surface area of the moisture thereby substantially increasing the rate of evaporation of the moisture through the hydrophobic second layer (18). The spreading of the moisture by the hydrophilic layer also improves user comfort by preventing wet spots on the outside surface fabric (18) around the openings of the perforation. The invention includes compressive orthopedic support braces for the wrist, elbow, thigh, knee and ankle formed from the material of the invention in sizes suitable for users having different physical stature. Orthopedic support braces formed from the composite material of the present invention provide the support advantages of foam braces with the comfort of elasticized knit braces.
    • 甲多分复合材料(10)在形成压缩括号用于整形外科支撑身体部分的有用包括用户接触织物部(12),以从贴合两个不同的面料和中间部FORMED最外侧织物部(18)(20)而形成 从闭孔泡沫。 用户接触织物部(12)是具有由疏水性纤维形成的,并粘结到中间泡沫部(26)的表面(22)的多维拉伸特性的织物。 最外面的部分包括具有从亲水性纤维和具有由疏水性纤维形成的多维拉伸特性的第二织物层(16)而形成的多维拉伸特性的第一织物层(18)。 中间泡沫部(26)具有第一表面和第二表面(22,24)和具有穿孔(28)的多个那里通过从所述第一表面到所述第二表面。 所述泡沫体具有足以提供用于支撑所述主体部分有用压缩应变多维弹性特性。 最外部分的第一层(16)结合到所述中间部分(20)的第二表面(24)。 湿气从使用者的皮肤发射的穿过所述疏水用户接触部(12),以其中一旦其穿过所述穿孔(28)和由亲水性的第一织物层(16)扩散的中间部分(20)。 所发射的水分的由亲水性层(16)的扩展增加了水分的表面积从而基本上通过疏水性第二层(18)增加水分的蒸发速率。 由亲水性层的水分的扩散,从而通过防止在外侧表面织物(18)围绕所述穿孔的开口湿点提高了用户的舒适度。 本发明包括用于腕,肘,大腿,膝盖和脚踝在适用于具有不同物理身材的用户尺寸从本发明的材料形成压缩矫形支架支撑。 从本发明的复合材料形成的矫形支撑固定件提供泡沫支架的支撑优点带有弹性针织括号的舒适性。
