A new, improved drainage system has been specifically designed to provide either closed suction drainage for the ambulating patient or sump drainage for the patient confined to bed. This drainage system is made of silicone that has a hydrogel coating with a low coefficient of friction. This coating facilitates removal of the drain from the wound cavity and reduces the adherence of blood clots in the drainage system. A filter assembly is attached to the air vent lumen to remove particulate matter and bacteria from the air. Clinical evaluation of the filtered sump drainage system has confirmed its superiority over closed suction in its efficiency of removing fluids from the wound.
一种全新改良的引流系统经过专门设计，可为能走动的患者提供封闭吸引引流，或为卧床患者提供双套管引流。该引流系统由硅胶制成，带有水凝胶涂层，摩擦系数低。这种涂层便于将引流管从伤口腔中取出，并减少引流系统中血凝块的附着。一个过滤器组件连接到排气腔，以去除空气中的颗粒物和细菌。对过滤式双套管引流系统的临床评估已证实，在从伤口清除液体的效率方面，它优于封闭吸引引流。
