Description
相关申请
本申请要求对2004年5月17日提交的美国临时专利申请No.60/571,837的优先权。
技术领域
本发明一般地涉及伤口处理的领域,具体来说,涉及一带有远处进入的入口的伤口腔室。
背景技术
人们使用各种技术来处理敞开的伤口。在某些情形中,敞开的伤口可用湿纱布或干纱布处理。然而,这样的处理可导致伤口过度疼痛脱水、失去流体和蛋白质、失热或延迟痊愈。为了延迟出现感染,烧伤伤口可另外用抗菌油膏和诸如此类的药膏进行处理。
敞开的伤口在干和湿之间适中的环境内出现较快的痊愈。局部发肿的伤口在覆盖一聚乙烯薄膜时比暴露在空气中时痊愈得更快。传统上,带有一定透水性的敷料对痊愈提供最佳的条件。
人们研究出伤口腔室用来保护敞开的伤口和提供处理部位的环境控制。例如,一示范的伤口腔室及其使用方法描述在Elof Eriksson的美国专利No.5,152,757中,其题为“伤口诊断和处理的系统”,本文援引其说明书的全部内容以供参考。
一伤口腔室通常包括一用来围绕病人伤口封闭一预定的表面区域的腔室。该伤口腔室密封到包围伤口的皮肤。除了其它特征之外,伤口腔室可具有一入口,该入口用来将处理流体和处理添加剂引入到伤口腔室内,并从伤口腔室抽出伤口流体和/或空气。这样的操作通常使用一注射器或类似的供应/抽取装置来实施。例如,入口可以是一由自密封材料制成的注射入口,一中空的钢针可通过该注射入口。紧靠病人使用钢针会造成伤害病人的危险并还会伤害到医护人员。还存在钢针损坏伤口腔室的附加的危险。在某些门诊应用中,伤口腔室本身可用诸如纱布或弹性绑带之类的二次敷料或覆盖物进行覆盖。在这样的情形中,一直接位于腔室上的入口可用二次敷料覆盖,以使其不可进入。
本发明致力于克服或至少减少一个或多个上述问题的影响。
发明内容
本发明的一个方面是一伤口的敷料,其包括一敷料底、一腔室、一管,以及一入口。该腔室从敷料底延伸而形成一处理空间。该管具有一连接到腔室的第一端。管与处理空间连通。入口连接到管的一第二端。
附图的简要说明
本发明可参照以下结合附图所作的描述予以理解,其中,相同的标号指示相同的元件,且在附图中:
图1是带有一从腔室引导到一入口的管的伤口敷料的立体图;
图2是图1的伤口敷料的侧视截面图;
图3是一连接到图1的伤口敷料的管的配件的立体图;
图4是在图1的伤口敷料的管的端部处的由自密封材料制成的入口的立体图;
图5是一可用于图1的伤口敷料的可坍瘪管的立体图;
图6是一带有插入到图5的可坍瘪管内的柔性供应末端的注射器的立体图;以及
图7是装配有一配件和自密封材料的一辅助端口的供应管的立体图。
尽管本发明易于作出各种修改和替代的形式,但借助于附图中的实例已经示出了特殊的实施例并在这里作详细地描述。然而,应该理解到,本文中的特殊实施例的描述并不意图将本发明限制在所揭示的特殊形式,刚好相反,本发明正意图涵盖落入由附后权利要求书定义的本发明的精神和范围之内的所有修改物、等价物和替代物。
具体实施方式
尽管本发明可实施为任何的若干种不同的形式,但这里所描述的本发明应理解到,本发明的揭示应认为是阐述示范的本发明,其不意图将本发明限制在所示的具体实施例。除非明确地指明“关键的”或“根本的”,否则,在本应用中没有可认为是对于本发明的内容是关键或根本的。
首先参照图1和2,图中示出伤口敷料20的立体图。伤口敷料20包括一形成一处理空间24的腔室22以及一可密封到病人伤口30上的皮肤表面28的敷料底26。在所示的实施例中,腔室22具有一带有弯折23的皮老虎结构。然而,本发明不局限于此,也可使用其它的结构。一粘结剂材料可设置在敷料底26的底表面上,以便提供一具有足够粘结强度的流体液密的密封,从而防止不留心移走伤口敷料20或在病人正常运动过程中打破流体液密的密封。本技术领域内的技术人员熟知许多足可用于该目的的粘结剂材料。
一管32附连到腔室22并与处理空间24连通。管32可永久地固定在腔室22,或可设置一配件25以允许移去管32。管32的远端终止在一入口34内。在一实施例中,入口34可以是一阴的路厄(Luer)配件。如本文中所使用的,术语入口和配件可以互换地使用,视特定的实施例而定。一配件通常指一装置,其与一互补的接口装置匹配,而一入口可涉及一装置,诸如针那样的某些东西可插入其中。管32可以终止在如图所示的腔室22的一壁处,或它可延伸通过壁一距离,终止在处理空间24内。管32密封到腔室22,密封的方式达到防止液体或空气从处理空间跑逸。尽管仅示出一个管32和入口34,但本发明不局限于此,为进入到处理空间24,可设置在多个管32和相关的入口34。一个管32和入口34可用作为一进口,以便将处理物质提供到处理空间24,而另一个管32和入口34可用作为出口,以便从处理空间24中移去物质。这样一进口和出口的结构可用于管理一连续的处理流。
敷料底26具有各种实施方案。例如,敷料底26可以是一适于将腔室22固定到肢上的箍带。在这样一实施例中,敷料底26可具有一诸如细绳、带、绑带、接片等的不同的封闭终止,以代替或组合围绕伤口23固定伤口敷料20的粘结材料。敷料底26也可位于不靠近伤口30的身体的部分上。例如,伤口23可以位于手或前臂上,而敷料底26可附连到上臂上的身体。一位于头皮上的伤口23可要求敷料底26设置在前额上和围绕到颈部。
现转向图3,一诸如注射器之类的供应/抽取装置36可与入口34接合,以允许将处理流体和/或处理添加剂供应到处理空间24,或从处理空间内移出液体或气体。例如,供应/抽取装置36可包括一配件38,诸如一与用作入口34的阴的路厄配件互补的阳的路厄配件。在互补的阴和阳路厄配件的情形中,阳配件38在供应/抽取装置36上的转动打开了从管32延伸的阴入口34内的阀。供应/抽取装置36可包括所示注射器之外的其它装置。例如,供应/抽取装置36可包括一刚性或柔性的容器,用来保持可供应到处理空间24内的一个或多个液体或粉末处理物质。
管32的长度可随特定实施例而变化。在提供管32为了增加供应/抽取装置36之间的距离以保护病人和/或腔室避开针的情形中,管应该至少长于针。在伤口敷料20用来被二次敷料覆盖的情形中,管32可以更加长。例如,管32的长度可以在1”和24”之间。管32通常为柔性并可根据具体的应用在自身上折叠起来。
图4示出一实施例,其中,入口34由自密封材料构造。在此实施例中,供应/抽取装置36可以是一具有一中空钢针39的注射器,钢针39通过自密封入口34插入,以允许注入处理流体和/或处理添加剂,和/或从处理空间24内抽出伤口流体或空气。
参照图5和6,图中示出另一实施例,其中,图1的管32是一柔性坍瘪材料形成的通常平躺的坍瘪管40。柔性末端42可在坍瘪管40的全长上插入,从而穿出坍瘪管40并直接延伸入处理空间24内。在某些实施例中,例如,在添加流体的情形中,柔性末端42可短于坍瘪管40。坍瘪管40按需要可膨胀而允许柔性末端42和/或处理流体插入。当柔性末端42抽出时,坍瘪管40坍瘪并相对于处理空间24形成水密和气密的密封。在某些实施例中,坍瘪管40可具有一展开端43,那里它与腔室22接口,即,或者终止在腔室22处,或者延伸到腔室22内。柔性末端42可定位在展开端43内,然而还未在处理空间24内以允许流体从处理空间24内取出。
如图7所示,图1的管32可以装备有一入口44,其是一诸如阴的路厄配件那样的配件,以及一位于分支管48上的由自密封材料形成的辅助入口46。提供两个入口44、46可允许使用者使用针或无针的供应/抽取装置36而增加伤口敷料20的灵活性。
管32允许入口34位于离开皮肤表面28、伤口30和腔室22一距离处。这里,如果处理流体使用一针引入到处理空间24内,则可减小不留心接触病人或护理人员或损坏腔室22的可能性。再者,如果伤口敷料20被二次敷料(未示出),则伤口30仍可通过管32得到处理而不需移去二次敷料。
上述伤口敷料20具有多种应用。管32可以用来引入各种处理流体和/或添加剂。伤口敷料20允许监视伤口,这可用来加快痊愈的过程。腔室22允许肉眼监视伤口30本身以及监视处理空间24内的流体。该种监视提供了反馈以有助于精确地控制处理的变数和便于进行研究。从系统中抽出的流体可分析各种因素,诸因素指明伤口痊愈的状态,也指明有害因素的存在,诸如微生物、低氧、高二氧化碳和不利的pH。流体可进行化验,测出每cc流体中细菌和其它微生物的数量和类型,细胞的数量和类型,蛋白质的数量和类型,以及其它诸因素。也可实施伤口生理学和病人的临床诊断。诊断之后,可开始伤口30的进一步处理,即引入处理添加剂和控制处理的变数。根据伤口的类型,可化验抽出的流体:(a)微生物的存在,(b)细胞,(c)蛋白质数量和类型,(d)化学品,(e)氧,(f)二氧化碳水平,和/或(g)pH。该数据可记录和用于伤口诊断。一旦诊断完成,可因此调整流体处理的干预。
当分析抽出的流体时,也可测量由伤口30形成的附加的生长因素。可进行化验的附加因素是各种发炎介质和各种抗原存在和数量。抗原的存在可用作一重要的诊断目的并可用特殊的抗体进行化验,抗体可通过伤口腔室供应。该信息用来确定替换什么和如何来治疗,并可表明伤口30的改善。伤口敷料20建立一环境,该环境允许身体产生的有益因素存在。
处理材料的示范的但不排外的清单包括麻醉剂、抗生素、化学治疗剂、生长因子、细胞培养介质、氧、缓冲剂、酶以及免疫调谐剂。添加的细胞可包括迁移到伤口30内之前遗传地修正的细胞,或可包括诸如DNA、基因、遗传材料、遗传媒介等的其它的基因治疗添加剂。
伤口敷料20还允许控制处理空间24内的处理环境。处理变数的示范的但不排外的清单包括温度、胶体渗透压力、pH、离子浓度、葡萄糖浓度、氨基酸含量、脂肪浓度、氧浓度以及二氧化碳浓度。
通过控制处理变数和添加选定的处理添加剂,可实施各种处理的技术。根据本发明,本技术领域内的技术人员可识别到许多如此的处理技术,本发明的应用不局限于任何特定的处理。
借助于图示,一可根据本发明实施的处理的非限制实例包括细胞处理技术,诸如应用干细胞、基因治疗药物,或细胞基质凝胶悬浮质,包括感染处理技术,诸如抗菌或细菌抑制的技术,或诸如负压治疗的一般处理技术。
上述特定实施例只是为了说明而已,因为本技术领域内的技术人员获益于本发明的描述后可明白到本发明可以作出修改并以不同但等价的方式实践本发明。此外,除了如附后权利要求书所描述的之外,并不意图限制本文所示的结构和设计的细节。因此,上述特定实施例显然可变化或修改,且所有如此的变化都被认为纳入本发明的范围和精神之内。因此,这里所要寻求的保护一概如附后权利要求书之阐述。
