具体实施方式 Detailed ways
下面通过实施例结合附图对本实用新型作进一步的描述。 Below by embodiment in conjunction with accompanying drawing, the utility model is further described.
如图1、图2所示，一种医用复合水凝胶敷料，包括水凝胶层1和保护层2，所述水凝胶层1为透明的，所述保护层2为聚氨酯膜层，所述聚氨酯膜层具有自粘性，所述聚氨酯膜层位于水凝胶层1的上部，所述聚氨酯膜层印有方格网。本实用新型的水凝胶层1由亲水性高分子材料制成，应用于干燥结痂的伤口表面，水凝胶中的水分可转移到干燥创面，软化硬痂，进而将其清除，促进创面的快速愈合；另外，水凝胶层透明度高，可定性观察创面愈合情况。保护层2可有效地阻止细菌等微生物的入侵，防止创面的感染，而且可实时定量记录创面愈合情况，便于伤口的护理。 As shown in Figure 1 and Figure 2, a medical composite hydrogel dressing includes a hydrogel layer 1 and a protective layer 2, the hydrogel layer 1 is transparent, and the protective layer 2 is a polyurethane film layer, The polyurethane film layer has self-adhesiveness, the polyurethane film layer is located on the upper part of the hydrogel layer 1, and the polyurethane film layer is printed with a grid. The hydrogel layer 1 of the present utility model is made of hydrophilic macromolecule material, and is applied to the wound surface of dry scab. Rapid wound healing; in addition, the hydrogel layer has high transparency, which can qualitatively observe the wound healing. The protective layer 2 can effectively prevent the invasion of microorganisms such as bacteria, prevent infection of the wound surface, and can record the wound healing situation quantitatively in real time, which is convenient for wound care.
