Description

一种负压封闭弓 I流专用敷料结枸
技术领域 本发明涉及医疗器械， 具体是一种医用负压封闭弓 I流专用敷料结构。 背景技术 临床上， 各种急慢性创面、 溃疡等发病率较高， 是常见病和多发病。 传统的 创面换药和引流等方法面临着创面感染不易控制、 费时长、 病人痛苦、 医护人员 工作量大等问题， 如何提高相关疾病的治疗水平， 是医学上急需解决的问题之一。 在欧美地区， 近二十年来在外科领域不断发展的负压封闭引流技术 （Vacuum Seal ing Drainage, VSD ) ， 近几年也在国内发展迅猛， 已基本在各大医院推广普 及， 特别是骨科、 烧伤整形科等应用较多。 针对开放性伤口治疗的 VSD技术的基本操作方法为： 各种创面清创后， 将聚 乙烯醇 (PVA) 等泡沫材料作为创面和引流管之间的中介， 然后用医用粘贴性半透 膜密封材料密封创面， 引流管后端连接各种负压源， 高负压吸引进行治疗。 现有的采用 VSD技术的负压引流装置基本结构主要有两种: A、 包括一根长引流管和块状的医用泡沫材料， 引流管前段管壁上开有多个引 流用侧孔且从块状医用泡沫材料的侧边水平插进并包裹于医用泡沫材料之中。 使 用时另用医用半透膜粘贴密封， 引流管应用 "系膜法"或 "戳孔法"进行密封。 发明人曾对上述设计做了改进， 增加了冲洗管， 以实现创面冲洗功能， 使用 方法与上述结构基本相同。
B、 包括一根带有吸盘结构的引流管和块状的医用泡沫材料。 使用时将医用泡 沫材料覆盖或填塞创面， 医用粘贴性薄膜将创面和医用泡沫材料整体密封， 医用 薄膜上开有一个孔并在孔上密封地设有一垂直的吸盘式管接头， 然后引流管固定 在垂直吸盘式管接头上。 但上述两种采用 VSD技术的负压引流装置具有以下缺点： 第一种方案因为人 体呈不规则形体， 创面所处的位置， 创面面积大小和形状， 创面周围正常皮肤情 况， 以及手术时其它医疗器械的使用等均影响专用敷料和创面密封。 特别在处理 较大创面时， 因为需要使用较多的专用敷料， 如果较长的引流管直接连接在医用 泡沫材料上， 必然导致从敷料中引出的引流管数量多， 这样一来， 不仅引流管周 围不易密封， 而且引流管会干扰整个创面和周围正常皮肤的密封， 导致在创面上 设计和拼接敷料， 利用医用粘贴薄膜密封创面困难， 耗时长， 甚至需要专业的贴 膜密封人员才能操作； 第二种方案引流管和泡沫材料依靠吸盘结构连接， 吸盘放 置在泡沫材料的外表面， 属于点状接触， 因为受到负压传导的限制， 引流管吸引 和引流的实际范围小， 大范围的负压传导有限， 不适用于较大面积创面的治疗， 直接影响治疗效果， 特别是这种吸盘结构式负压封闭引流技术， 在治疗时间较长 时， 创面渗出和坏死物质堵塞泡沫材料的开孔， 必然导致治疗失效； 第一种方案 引流管应用 "系膜法"或 "戳孔法"进行密封， "戳孔法"因为需要在人体上戳孔， 目前已很少使用。 "系膜法"是目前使用最广泛的方法， 但因为人体出汗和创面渗 液，人体活动牵拉等原因， "系膜"处医用薄膜会松动， 出现缝隙， 产生漏气现象， 造成负压减小， 甚至消失， 直接影响治疗可靠性； 还有， 使用 VSD技术治疗时， 以上两种方案所使用的半透膜实际都是双向透气膜， 医用泡沫材料被抽负压真空 的环境下， 空气会透过半透膜向内渗透漏气， 同样会造成负压减弱甚至消失， 所 以目前广泛使用医院中心负压或电动吸引器持续抽吸， 才能保证治疗效果， 但这 样以来， 病人活动不便和增加了医疗成本， 也极大地限制了负压封闭引流技术的 使用范围； 另外， 以上二种方案均因为空气会透过粘贴半透膜向内渗透漏气， 形 成创面负压密封引流专用敷料内产生抽风效应， 必然导致泡沫材料和创面真空脱 水加速加快， 泡沫材料变干变硬， 病人创面渗出和脱水加速， 特别是大面积创面， 甚至会导致病人全身脱水或休克的不良事件。 以上二种方案对医护人员的理论知 识和临床操作技术水平均要求较高， 因为临床使用时出现不良事件的可能性很大， 关系到病人的生命安全， 直接影响到该技术的标准化， 限制了 VSD技术的推广使 用。 发明内容 本发明的目的， 就是提供一种将引流管分为外接管与内置管， 且两者的连接 为可拆装式连接， 方便使用的负压引流装置。 在进一步的改进后， 本发明还可以满足创面密封严密不易漏气、 贴膜密封方 便的要求。 本发明的目的可以通过以下的技术方案来分别实现： 一种负压封闭引流专用敷料结构， 包括引流管和医用泡沫材料， 其特征是： 所述的引流管分为外接管和内置管， 所述内置管部分或全部包裹于所述的医用泡 沫材料之中且管壁上开有多个引流用侧孔， 所述的内置管的一端或中间连接开口 处于所述的医用泡沫材料表面外的接头， 所述的外接管可拆装地通过接头与内置 管连通 （使用时方连接)， 所述的外接管后端接负压源。 所述的泡沫材料外表面上覆盖有不透气材料层， 所述不透气材料层的面积等 于或大于医用泡沫材料。 这样既可以另行使用粘膜， 也可以直接将医用泡沫材料 固定在皮肤上。 所述的大于医用泡沫材料的不透气材料层的外周边具有粘贴性。 所述的接头与所述的内置管一体做出。 所述的内置管至少一根， 引流时内置管侧壁的引流用侧孔起到吸液产生负压 的作用， 多根的内置管可以扩大产生负压和引流的范围， 内置管的多少及长度可 以根据需要设计或者修剪， 满足需要大范围负压引流的需要； 不透气材料层可以 起到密封泡沫材料的作用， 当膜下空气被抽出后会形成负压环境， 而且负压不易 消失。 使用时， 将本装置覆盖在开放性伤口或创面上， 敷料可采用医用聚乙烯醇泡 沫材料或医用聚氨酯泡沫材料等， 然后应用医用粘贴薄膜将本装置粘贴和密封于 正常皮肤上。 或应用本装置已粘贴在敷料表面的不透气材料层与创面周边的皮肤 相粘贴上； 然后连接外接管和负压源， 启动负压源就可以对创面渗液或坏死物质 进行引流， 负压源一般为 -12〜- 80kPa。 在本申请之前， 未发现有同样的产品面世或发表， 与现有技术相比， 本发明 产生了意想不到的有益效果：
( 1 ) 引流时内置管起到吸液引流作用， 可以设置多根内置管扩大引流范围， 内置管长度可以根据需要设计或者修剪， 使其包裹于所述的医用泡沫材料之中， 满足实际需要；
( 2 ) 因为外接管与内置管的连接为可拆装式连接， 所以实际使用中只需将泡 沫材料和周围皮肤之间进行密封， 贴膜密封操作结束后， 再将外接管与泡沫材料 上的内置引流管接头相连接， 完全避免了引流管对专用敷料贴膜密封的干扰， 简 化了专用敷料与周围正常皮肤的密封过程， 大大地降低了贴膜密封的难度， 另外， 可以简化创面敷料设计、 敷料拼接、 敷料与周围皮肤缝合固定的操作方法， 节约 手术时间。 ( 3 ) 因为外接管和敷料表面相连接， 避免了引流管周围皮肤出汗、 病人活动 牵拉等影响， 极大地减少负压封闭引流技术术后漏气， 负压消失等临床不良事件， 直接提高临床治疗效果。
( 3 ) 采用不透气材料层， 可起到对泡沫材料取到完全密封的作用， 当膜下空 气被抽出后会形成负压环境， 负压不易消失， 防止了泡沫材料脱水变干变硬， 以 及病人创面渗出和脱水加速， 特别是大面积创面， 避免了导致病人全身脱水或休 克的不良事件的可能性。 另外， 较小的创面就可以使用便携手动式的负压源。 因 为不用连接电动负压机或持续吸引的中心负压源， 不仅可以方便病人活动， 而且 扩大负压封闭引流技术适应症和使用范围。
(4) 不透气材料层的面积大于医用泡沫材料， 且不透气材料层的外周边具有 粘性， 使用时将根据创面大小和形态， 将装用敷料互相拼接和修剪成创面的形状 和大小， 将拼接好的医用泡沫材料放在创面上， 然后将不透气材料层的外周直接 黏贴在创口周边的皮肤上， 这样以来， 不仅大量节省了医护人员在创面上缝合拼 接敷料， 以及敷料和创面周围皮肤缝合固定的时间， 而且使用方便， 操作简单， 对贴膜技术水平要求低， 不需要配备专门的贴膜人员， 有利于负压封闭引流技术 的标准化， 适宜推广使用。 附图说明 图 1是本发明实施例一的剖面图 （沿图 1的 A-A线）; 图 2本发明实施例一去掉外接管后的俯视图； 图 3是具体实施例二去掉外接管后的俯视图； 图 4是具体实施例三剖面示意图。 具体实施方式 图 1〜2所示的负压引流装置是本发明的实施例一， 包括引流管 1和医用泡沫 材料 2， 引流管 1分为外接管 3和至少一根的内置管 4， 内置管 4全部包裹于医用 泡沫材料 2之中、且内置管 4管壁上开有多个引流用侧孔 5, 内置管 4的一端连接 一开口处于医用泡沫材料 2表面外的接头 6，接头 6垂直于医用泡沫^ ί料 2表面（当 然也可以从侧面插入）， 外接管 3使用时通过接头 6与内置管 4连通， 外接管 3后 端接负压源。 图 3所示的实施例二， 与实施例一不同之处在于内置管 4部分包裹于医用泡 沫材料 2之中、 且内置管 4有两根， 且是从中间连接接头 6的。 图 4所示的实施例三， 与实施例一不同之处在于泡沫材料 2的外表面上覆盖 有不透气材料层 7,不透气材料层的面积等于或大于医用泡沫材料（本例为大于）， 大于医用泡沫材料的不透气材料层的外周边具有粘性并覆盖有粘性保护纸 8。这样 既可以另行使用粘膜， 也可以直接将医用泡沫材料固定在皮肤上； 且接头 6与内 置管 4一体做出。 替换页 （细则第 26条）
