A wound dressing (500) includes a flexible layer of material (501) that is treated with an antimicrobial agent (604), such as PHMB. The antimicrobial agent (604) ionically bonds to cellulose fibers (502) of the flexible layer of material (501) through a bonding agent (601). The bonding agent (601) increases the number of available carboxylate bonding groups beyond a characteristic carboxylate bonding group density normally associated with untreated cellulose fiber such that more antimicrobial agent (604) can be bonded to the flexible layer of material (501). An optional antifungal agent (606) can also be applied to the flexible layer of material (501).
伤口敷料 (500) 包括一层柔性材料 (501),该材料经过抗菌剂 (604) 处理,例如
PHMB。抗菌剂 (604) 通过粘接剂 (601) 与柔性材料层 (501) 的
纤维素纤维 (502) 发生离子键合。键合剂(601)增加了可用
羧酸键合基团的数量,超过了通常与未处理
纤维素纤维相关的特征
羧酸键合基团密度,从而使更多的抗菌剂(604)可以键合到柔性材料层(501)上。还可以在柔性材料层(501)上涂抹任选的抗真菌剂(606)。
