    摘要： Medical dressings are disclosed that include multiple exposed pressure sensitive adhesives. One of the pressure sensitive adhesives includes a bioactive agent and is substantially contact transparent. In some embodiments, all of the adhesives are substantially contact transparent. Also provided are methods of manufacturing the medical dressings. By providing multiple exposed pressure sensitive adhesives, the pressure sensitive adhesive formulations can be varied to provide desired properties in different areas of the dressing. A pressure sensitive adhesive that exhibits relatively high lack to skin may be provided around the periphery of the dressing while a pressure sensitive adhesive incorporating a bioactive agent is provided in the center of the dressing Alternatively, a higher tack pressure sensitive adhesive may be provided at two opposing sides of the dressing with a bioactive adhesive located in between the opposing portions of higher tack adhesive. The present invention also provides methods of transferring adhesives using a mask such that the adhesive is transferred to selected areas of a receiving surface the mask may he provided in the form of a liner including a plurality of voids formed therein.

    摘要翻译： 医用敷料游离缺失盘也包括多个暴露的压敏粘合剂。 一项所述的压敏粘合剂的包括生物活性剂，并基本上接触透明。 在一些实施例中，所有的粘合剂都基本上接触透明的。 因此，提供了制造医用敷料的方法。 通过提供多个暴露的压敏粘合剂，所述压敏粘合剂式蒸发散可以改变在所述敷料的不同区域，以提供所需的性质。 一种压敏粘合剂没有表现出相对高的涂料皮肤可围绕所述敷料的周边，同时压敏粘合剂结合的生物活性剂在可替代地，敷料的中心处设置被提供，较高的粘性压敏粘合剂可在两个被提供 相对的敷料的侧面与位于高粘性的粘结剂的相对部分之间的生物活性粘合剂。 因此，本发明提供了使用检查掩模传递环粘合剂的方法所做的粘合剂转移到所述掩模可以在他的衬垫的形式提供了一种包括形成于其中的空隙的多个A接收表面的选定区域。
