Description

皮肤伤口辅助愈合装置 技术领域
本发明涉及一种皮肤伤口辅助愈合装置，特别是一种用于医疗卫生领域的皮肤伤口辅助愈合装置。
背景技术
现代外科手术切口或创伤伤口的闭合治疗方案，必须同时考虑如下影响伤口成功愈合的相关要素例如：伤口渗出液及坏死物的及时清洗引流、皮肤切口处的死腔消除，伤口皮缘的平整对合、伤口张力的减张、避免缝合带来新的缝合创伤、保护创口的湿润覆盖等相关要素。
目前现有技术中的负压敷料覆盖伤口后，只能满足清洗引流渗出液及坏死物，无法满足切口皮缘的对合及保证对合平整、伤口张力的减张需求；而现有技术中采用皮肤切口锁合器。则只能将皮肤切口的两侧，简单的向中线拉和。在拉和过程中需要依靠外力及复杂的拉和结构和复杂的拉和步骤。且皮肤各处受力不均，特别在不规则的弯曲形状的伤口，将会造成伤口一些地方已经拉拢过度而一些地方还无法対合，并且该装置无法满足皮肤切口渗出液及坏死物的清洗引流，无法消除皮肤切口处的死腔，无法满足不规则曲线伤口缝合，无法满足保护创口的湿润覆盖。上述现有技术中均没有考虑为伤口提供保证伤口皮缘的对合平整的支持结构。因此现有技术中还没有一种完整的皮肤伤口闭合治疗方案，其既能满足及时清洗引流伤口渗出液及坏死物、确保消除切口死腔，又同时能保证伤口皮缘的紧密对合及对合平整、能均匀有效减张、能避免新的缝合创伤、具备保护创口湿润覆盖。
发明内容
本发明所要解决的技术问题是提供一种结构简单，操作方便，能同时具备伤口坏死物负压清洗引流、消除皮肤切口处的死腔，能自动牵引伤口皮缘对合、能辅助伤口皮缘对合平整，能适应不规则曲线伤口缝合，保护伤口湿润覆盖的愈合环境，同时又使用舒适易维护的皮肤伤口辅助愈合装置。
为解决上述技术问题本发明采用的皮肤伤口辅助愈合装置，包括密封膜、引流管、基带、封口端和弹性上盖，所述弹性上盖连接在基带的上方，并且基带可相对弹性上盖沿直线移动，所述封口端设置在弹性上盖的两端，并且封口端、基带和弹性上盖形成一 个密封腔，所述密封膜覆盖在封口端、弹性上盖和基带上，所述引流管将密封腔的内外连通。
进一步的是，所述弹性上盖上设置有滑块，所述基带上设置有导槽，所述滑块嵌入导槽之中。
进一步的是，所述弹性上盖上设置有滚轮，所述基带上设置有导轨，所述滚轮与导轨相配合。
进一步的是，所述基带上设置有棘齿，弹性上盖上设置有挡片。
进一步的是，还包括敷料，所述敷料设置在弹性上盖下方。
进一步的是，所述基带下方设置有粘合剂层。
进一步的是，所述弹性上盖为分段结构，所述密封膜为分段结构。
进一步的是，还包括皮肤切口锁合装置，所述皮肤切口锁合装置连接在皮肤伤口两侧的基带上。
本发明的有益效果为：密封腔可以将皮肤伤口与外界环境有效隔绝，使得皮肤伤口保持清洁状态。使得密封腔内部形成负压环境，在负压作用下，基带自动向伤口的中部并拢，从而带动伤口两侧的皮肤向中间靠拢，实现拉合皮肤的作用，并且弹性上盖产生形变，向下紧贴基带，形成一个基准平面，同时伤口两侧的皮肤会向弹性上盖的基准平面贴紧，由于上盖的限制皮肤在生长愈合过程中便不会出现翻卷和翘曲的现象，其在愈合的过程中始终保证规则平整的形态。

具体实施方式
下面结合附图对本发明作进一步说明。
如图1、图2及图3所示，本发明的皮肤伤口辅助愈合装置，包括密封膜1、引流管2、基带3、封口端4和弹性上盖5，所述弹性上盖5连接在基带3的上方，并且基带 3可相对弹性上盖5沿直线移动，所述封口端4设置在弹性上盖5的两端，并且封口端4、基带3和弹性上盖5形成一个密封腔，所述密封膜1覆盖在封口端4、弹性上盖5和基带3上，所述引流管2将密封腔的内外连通。封口端4、基带3和弹性上盖5形成一个密封腔。在外部覆盖一层密封膜1，可以有效增加密封效果。弹性上盖5采用弹性材料制成，使用时，先将基带3与伤口11两侧的皮肤粘合，然后利用引流管2将密封腔内部空气抽到密封腔外部，使得密封腔内部形成负压环境。该密封腔可以将皮肤伤口11与外界环境有效隔绝，使得皮肤伤口11保持清洁状态。并且将密封腔内气体抽出后，该密封腔形成负压腔体，在负压的作用下，基带3自动向伤口11的中部并拢，从而带动伤口11两侧的皮肤向中间靠拢，实现拉合皮肤的作用，可以有效帮助皮肤愈合。由于伤口11处于负压环境中，在拉合皮肤的同时，皮肤伤口11辅助愈合装置可以消除拉合过程中皮肤伤口11深处产生的死腔。在拉合过程中利用引流管2及时排出伤口11渗液，保持伤口11清洁，防止皮肤感染，更利于皮肤愈合。由于基带3可相对上盖沿直线移动，因此基带3在负压作用下带动皮肤伤口11向中间并拢时不会受到上盖影响，导致基带3在移动过程中变形，引起伤口11两侧皮肤产生皱褶，破坏伤口11愈合效果。在负压作用下，弹性上盖5产生形变，向下紧贴基带3，形成一个基准平面，同时伤口11两侧的皮肤会向弹性上盖5的基准平面贴紧，由于上盖的限制皮肤在生长愈合过程中便不会出现翻卷和翘曲的现象，其在愈合的过程中始终保证规则平整的形态，大大提高了皮肤愈合的效果。
所述弹性上盖5上设置有滑块6，所述基带3上设置有导槽7，所述滑块6嵌入导槽7之中。基带3和弹性上盖5通过滑块6和导槽7来实现可靠连接和沿直线的相对运动。
所述弹性上盖5上设置有滚轮，所述基带3上设置有导轨，所述滚轮与导轨相配合。滚轮和导管可以作为实现基带3和弹性上盖5可靠连接和沿直线的相对运动的另一种优选方式。
所述基带3上设置有棘齿8，弹性上盖5上设置有挡片9。基带3在负压作用下将伤口11拉合的过程中难免受到外部干扰，这时基带3容易后退将已经部分愈合的伤口11拉裂。而基带3上设置的棘齿8与弹性上盖5的挡片9配合，可以使基带3只能往伤口11中部并拢，而不能反向运动，从而有效防止基带3将已经部分愈合的伤口11拉裂。
还包括敷料，所述敷料设置在弹性上盖下方。料中饱含有帮助伤口11愈合的药剂，更有利于伤口11的快速愈合。
所述基带3下方设置有粘合剂层10。在使用时将基带3靠近皮肤的下方涂刷上粘合剂，使基带3与伤口11两侧的皮肤紧紧拉紧。
所述弹性上盖5为分段结构，所述密封膜1为分段结构。弹性上盖5与密封膜1采用分段结构，整个装置由多个分段沿着伤口11的轮廓拼接而成，采用前述结构可以适应形状不规则的伤口11。
还包括皮肤切口锁合装置，所述皮肤切口锁合装置连接在皮肤伤口两侧的基带3上。皮肤切口锁合装置可以将伤口两侧的皮肤拉拢。
