    • The present invention provides an orthopedic casting article comprising an apertured, extruded sheet. The present invention also provides a method of enclosing a body member, comprising the steps of: heating an apertured, extruded sheet comprising a low temperature thermoplastic polymer having a softening or melting temperature less than about 90.degree. C.; wrapping the article about the body member; and molding the wrapped article about the body member such that the article is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint. The present invention also provides a method of enclosing a body member, comprising the steps of: initiating the curing of an apertured, extruded sheet comprising a viscous curable resin having a sufficient yield stress to resist flow at ambient temperature for extended periods of time; wrapping the article about the body member; and molding the wrapped article about the body member such that the article is used as an orthopedic casting material and has a sufficient number of apertures after application to the patient to allow moisture vapors produced by the skin to freely escape through the cast or splint. The apertured, extruded sheet may optionally contain a filler associated with the resin. The incorporation of fillers adds substantially to the strength of the cured casting material as well as to the handling properties of the uncured casting tape or bandage.
    • 本发明提供一种包括有孔挤压片材的整形外科制品。 本发明还提供一种封闭主体部件的方法,包括以下步骤:加热具有软化或熔化温度低于约90℃的低温热塑性聚合物的多孔挤压片材; 包裹身体成员的文章; 并且将包裹的制品模制在身体构件周围,使得该制品用作矫形铸造材料,并且在施用到患者之后具有足够数量的孔,以允许由皮肤产生的水分蒸汽通过铸件或夹板自由逸出。 本发明还提供一种封闭主体部件的方法,包括以下步骤:启动具有足够屈服应力的粘性可固化树脂的有孔挤出片材的固化,以抵抗在环境温度下长时间流动; 包裹身体成员的文章; 并且将包裹的制品模制在身体构件周围,使得该制品用作矫形铸造材料,并且在施用到患者之后具有足够数量的孔,以允许由皮肤产生的水分蒸汽通过铸件或夹板自由逸出。 有孔的挤出片材可以任选地含有与树脂相关的填料。 填充剂的添加基本上增加了固化的浇铸材料的强度以及未固化的浇铸胶带或绷带的操作性能。
