Abstract
功能性敷料，包括便于剥离的留沿膜和固定贴膜，在留沿膜和固定贴膜之间设有功能垫，固定贴膜背对功能垫的一面设有保护膜，在固定贴膜上设置多层回形或环形的胶条，一方面减少了固定贴膜与皮肤的粘接面积，另一方面，留下空隙使汗液能够挥发；在功能垫中设置了功能层和保湿层，使其中的药物成份作用于创口及周边组织，起到止血、抗菌、抑菌、消炎、镇痛、促进愈合、减小瘢痕形成和加速局部血液循环功能的作用。
Description
技术领域
本发明属于医疗用品技术领域，具体涉及一种用于体表组织创口、溃疡伤口、修复类伤口的功能性敷料。
背景技术
目前的创口敷贴大都具有消炎的功能，但一般不具备镇痛的功能，更不具备利用远红外线对创口周边肌体组织进行辐射，起到改善血液循环、减轻疼痛的功能。
由于敷贴会受到创口溢出液的污染以及长时间使用药效会降低，因此，需要及时更换。但目前的敷贴在使用中，常出现撕掉敷贴时才发现伤口已经感染发炎，这时再处理伤口，治愈时间相应变长，且创口痊愈后留下的疤痕更加明显。
另外，现有的敷贴，大多采用在固定贴膜上涂覆医用胶的方式来固定在皮肤上，在固定贴膜上涂覆医用胶通常都是采取满幅涂覆的方式，优点是能够有效固定，不足是要将固定贴膜从皮肤上撕开时容易拉扯皮肤导致创口部位疼痛，并且敷贴长时间粘贴在皮肤上，积液无法排出，易引起皮肤过敏。
在申请号为200410025842.9的专利中公开了一种术后切口敷贴的设计方法，采用在敷贴上固定永磁片产生磁场以促进伤口愈合，在不干胶基层的中部连接有水刺布，水刺布内包裹着吸水棉芯，吸水棉芯上贴有永磁片，具有良好的保湿性，具有一定止痛效果，由于永磁片具有较强的硬度并具有一定厚度，在使用过程中和更换时，永磁片容易对创口造成一定压力而导致疼痛；铁元素含量高，创口有溢液，容易生锈给创口造成二次污染。
因此，需要寻找一种粘贴稳固并且胶与皮肤接触面积更小，能够对创口进行检查、观察、消毒，并具有消炎、镇痛和加速血液循环功能的敷料。
发明内容
本发明的目的是针对上述技术现状，提供一种粘贴稳固并且胶与皮肤接触面积更小，能够对创口进行检查、观察、消毒，并具有止血、抗菌、抑菌、消炎、镇痛、促进愈合、减小瘢痕形成和加速局部血液循环功能的敷料。
本发明的技术方案是：功能性敷料，包括便于剥离的留沿膜1和固定贴膜2，在留沿膜和固定贴膜之间设有功能垫3，固定贴膜背对功能垫的一面设有保护膜4，所述的固定贴膜2选用透明的生物基材料膜或透气膜，沿固定贴膜2边缘设置加强框21，在固定贴膜面对功能垫的一面从边缘向中心设有多层回形或环形的胶条22，所述的功能垫3从固定贴膜向留沿膜的方向由反射层31、功能层32、保湿层33和防粘层34依次堆叠形成；所述的反射层31与固定贴膜2连接，所述的反射层31选用金属薄片或带有金属涂层的胶膜。
所述的功能层32采用点阵的方式安置在保湿层33面对反射层31的一面。
所述的保湿层33中含有酸碱度变色剂，当创口发炎时酸碱度变色剂变色；所述的反射层上设有观察窗。
所述的反射层31选用铝片或涂覆了银的PU膜。
所述的保湿层33采用含高分子吸水保湿材料成份,并掺杂有抗菌材料或生物光素复合医用材料的棉垫、甲壳素材料棉垫、纳米材料垫、涤纶垫、丙伦垫、聚丙烯垫或海绵。
所述的防粘层34表面涂覆有消炎杀菌药。
所述的功能层32选用生物炭或电气石或远红外陶瓷或矿物质盐或锗石或生物光素复合医用材料，所述的生物光素复合医用材料包括以下组份及含量(重量)为原料：玉石41～58％，珍珠粉3～9％，甲壳素2～4％，二氧化硅32～48％。
有益效果：
1、在固定贴膜上设置多层回形或环形的胶条，一方面减少了固定贴膜与皮肤的粘接面积，另一方面，留下空隙使汗液能够挥发；
2、在功能垫中设置了功能层和保湿层，使其中的药物成份作用于创口及周边组织，起到止血、抗菌、抑菌、消炎、镇痛、促进愈合、减小瘢痕形成和加速局部血液循环功能的作用；
3、在功能垫的功能层上设置了反射层，将功能层产生的向人体外辐射的能量反射向人体组织，起到更好的抗菌、抑菌、消炎、镇痛、促进愈合、减小瘢痕形成和加速局部血液循环功能的作用。
附图说明
图1是本发明撕去留沿膜后的主视结构示意图；
图2是本发明的侧视结构示意图；
图3是本发明的功能垫的侧视结构示意图；
图4是本发明的固定贴膜主视结构示意图。
具体实施方式
如图1、图2和图3所示，功能性敷料，包括便于剥离的留沿膜1和固定贴膜2，在留沿膜和固定贴膜之间设有功能垫3，固定贴膜背对功能垫的一面设有保护膜4，所述的固定贴膜2选用透明的生物基材料膜或透气膜，沿固定贴膜2边缘设置加强框21，防止卷边。在固定贴膜面向留沿膜的一侧的两端设有保护贴5，保护贴为对折的离型纸，保护贴的开口方向背对功能垫。
在固定贴膜面对功能垫的一面从边缘向中心设有多层回形或环形的胶条22。采用封闭的环路胶条，能够有效阻止外界空气流到创口上，给创口带来细菌及病菌，并且在胶条之间留有空隙，使汗液能够及时通过胶条之间的固定贴膜蒸发出去，以免因汗液积聚导致过敏或皮炎。
如图4所示，所述的功能垫3从固定贴膜向留沿膜的方向由反射层31、功能层32、保湿层33和防粘层34依次堆叠形成；所述的反射层31与固定贴膜2连接，所述的反射层31选用金属薄片或带有金属涂层的胶膜。所述的反射层将功能层及保湿层中物质产生的向外的辐射反射向人体，帮助促进血液循环、消炎及止痛。
所述的功能层32采用点阵的方式安置在保湿层33面对反射层31的一面，或者采用喷涂的方式覆盖在保湿层上，或者直接混合到保湿层中去。
所述的功能层32中含有酸碱度变色剂，当创口发炎时酸碱度变色剂变色；所述的反射层上设有观察窗。使用前，功能层表面的颜色是一致的，使用后，由于吸附了患者创口流出的体液，功能层的颜色会随体液的酸碱度的变化而变化。例如，当患者的创口感染发炎，创口液出的体液碱性增强，就会导致酸碱度变色剂变色，从而使功能层表面的颜色产生变化。因此，在实际的应用中，通过反射层上的观察窗观察到功能层的颜色变化，就能够根据颜色的变化判断创口的愈合情况，如果颜色变深，表示创口发炎需要对创口进行清理并更换功能性敷料。
所述的反射层31选用铝片或涂覆了银的PU膜。
所述的保湿层33采用含高分子吸水保湿材料成份,并掺杂有抗菌材料或生物光素复合医用材料的棉垫、甲壳素材料棉垫、纳米材料垫、涤纶垫、丙伦垫、聚丙烯垫或海绵。
所述的防粘层34表面涂覆有消炎杀菌药，如络合碘。
所述的功能层32选用生物光素复合医用材料或生物炭或电气石或远红外陶瓷或矿物质盐或锗石。
所述的生物光素复合医用材料包括以下较佳的组份及含量(重量)为原料：玉石41～58％，珍珠粉3～9％，甲壳素2～4％，二氧化硅32～48％。
上述实施例仅是用来说明解释本发明的用途，而并非是对本发明的限制，本技术领域的普通技术人员，在本发明的实质范围内，做出各种变化或替代，也应属于本发明的保护范畴。
