Description

一种创面微真空精准调控系统
技术领域
本发明涉及一种医疗器械，特别是一种创面微真空精准调控系统。
背景技术
由于现在工业的发展，空气中的微粒越来越多，人体表面的皮肤中藏有一些微小的灰尘而形成污垢。位于皮肤表面的污垢可以通过洗澡清理掉，但是位于皮肤深层的污垢通过洗澡清理不了。现代人通过尝试使用清吸液以及带化学物质的清理贴等含有化学物质去清理皮肤深层的污垢，虽然在一定程度上清理了皮肤深层的污垢，但是残留的化学物质会对皮肤造成影响。
还有就是伤口护理方面的。一般通过伤口贴将伤口保护起来。伤口贴一般为医用聚氨酯（PU）伤口贴，该医用聚氨酯（PU）伤口贴采用进口透气PU基材，并复合表层背衬基材，经分切、灭菌、包装制成。伤口贴只能用于小块的创伤应急治疗，从而起到暂时的止血，保护创面的作用。但是应该注意，使用的时间不宜过长。如果过久地使用它，伤口贴外层的胶布不透气。就会使伤口和伤口周围的皮肤发白，变软导致细菌的继发的感染。这样就会使伤口更加的恶化。其仅能在伤口或者创面不发生渗液的情况下提供利于伤口或者创面愈合的良好条件。然而，对于伤口或者创面大面积渗液时，由于伤口贴不能吸液，其渗液残留在伤口或者创面表面，一方面不利于伤口或者创面愈合，另一方面形成细菌滋生的病灶。另外，现有还有一些负压抽吸引流的创面贴，对伤口表面的渗液吸附以及将伤口深处的坏死组织吸出，但是这些创面贴需要外接电动负压源，因为电动负压源气流量、功率等原因，目前临床上电动负压源使用时，负压值最低不小于10-kpa。通过大量实验室实验，电动负压源负压显示表显示负压大小，约等于创面实际所承受的负压值，这样一来，由于创面实际所承受的压强不能很好的控制，尤其是压强过大，较强的抽吸作用会导致创面的新生上皮、皮岛、肉芽组织等损伤，原本能自然愈合的创面需要进行植皮手术。因此需要一种能够精准调控创面实际所承受的负压值小于5KPa的创面微真空精准调控系统。
发明内容
本发明的目的，在于提供一种创面微真空精准调控系统。
本发明解决其技术问题的解决方案是：一种创面微真空精准调控系统，包括真空泵、储液瓶、一端与储液瓶内部连通的抽吸导管、用于贴附在创面处的引流敷料层、位于引流敷料层上表面的医用贴膜、水封瓶以及一端插入到水封瓶内部的进气管，所述抽吸导管的另一端直接或者间接与引流敷料层的三维互通结构连通，所述真空泵通过第一管道和储液瓶连接，所述水封瓶通过水压导管直接或者间接与引流敷料层的三维互通结构连通，水封瓶内部盛装有液体，所述液体占水封瓶0.2~0.7的容积，所述水压导管的一端从水封瓶的上端面伸入到水封瓶内部后水压导管的末端位于液体液面上方，所述进气管的两端敞口，进气管的一端从水封瓶的上端插入到水封瓶内部后延伸到水封瓶底部。
作为上述技术方案的进一步改进，所述抽吸导管通过至少一个盘体与引流敷料层的三维互通结构连通，所述水压导管通过至少一个盘体与引流敷料层的三维互通结构连通。
作为上述技术方案的进一步改进，所述抽吸导管和水压导管共用一个盘体与引流敷料层的三维互通结构连通。
作为上述技术方案的进一步改进，位于所述水封瓶内的水压导管的末端与水封瓶的上内侧面齐平；或者，位于所述水封瓶内的水压导管的末端与水封瓶的上内侧面之间相差1~5mm。
作为上述技术方案的进一步改进，所述进气管的外表面中部往下依次布置有0.5KPa线、1KPa线、2KPa线和3KPa线。
作为上述技术方案的进一步改进，所述医用贴膜四周往外延伸出引流敷料的范围后形成能贴在创面处边沿外侧皮肤表面的贴翼。
作为上述技术方案的进一步改进，所述第一管道上安装有压力表。
作为上述技术方案的进一步改进，所述液体占水封瓶0.5或0.6的容积。
本发明的有益效果是：本发明通过设置水封瓶，通过水封瓶可以目视出引流敷料层内部的压力，若引流敷料层内部的压力超过水封瓶设定的压力，外部气体通过进气管、水封瓶以及水压导管进入创面内部，舒缓创面内部压力，防止出现创面内部压力过大而对于创面新生皮岛造成损伤。
附图说明
为了更清楚地说明本发明实施例中的技术方案，下面将对实施例描述中所需要使用的附图作简单说明。显然，所描述的附图只是本发明的一部分实施例，而不是全部实施例，本领域的技术人员在不付出创造性劳动的前提下，还可以根据这些附图获得其他设计方案和附图。
图1是本发明的结构示意图。
具体实施方式
以下将结合实施例和附图对本发明的构思、具体结构及产生的技术效果进行清楚、完整地描述，以充分地理解本发明的目的、特征和效果。显然，所描述的实施例只是本发明的一部分实施例，而不是全部实施例，基于本发明的实施例，本领域的技术人员在不付出创造性劳动的前提下所获得的其他实施例，均属于本发明保护的范围。另外，文中所提到的所有联接/连接关系，并非单指构件直接相接，而是指可根据具体实施情况，通过添加或减少联接辅件，来组成更优的联接结构。

通过设置水封瓶9，通过水封瓶9可以目视出引流敷料层5内部的压力，若引流敷料层5内部的压力超过水封瓶9设定的压力，外部气体通过进气管10、水封瓶9以及水压导管8进入创面内部，舒缓创面内部压力，防止出现创面内部压力过大而对于创面新生皮岛造成损伤。
进一步作为优选的实施方式，所述抽吸导管4通过至少一个盘体7与引流敷料层5的三维互通结构连通，所述水压导管8通过至少一个盘体7与引流敷料层5的三维互通结构连通。

进一步作为优选的实施方式，所述进气管10的外表面中部往下依次布置有0.5KPa线、1KPa线、2KPa线和3KPa线，3KPa线位于进气管10的最下端。进气管10外表面的刻度线可以根据具体的情况设置。位于进气管10最下端的刻度线为警戒线。当水封瓶9中出现气泡时，表面创面内部的气压超过水封瓶9设置的压力值，需要调整真空泵1的工作状态，降低创面内的压力值。
进一步作为优选的实施方式，所述医用贴膜6四周往外延伸出引流敷料的范围后形成能贴在创面处边沿外侧皮肤表面的贴翼。
进一步作为优选的实施方式，所述第一管道2上安装有压力表12。

以上是对本发明的较佳实施方式进行了具体说明，但本发明创造并不限于所述实施例，熟悉本领域的技术人员在不违背本发明精神的前提下还可作出种种的等同变型或替换，这些等同的变型或替换均包含在本申请权利要求所限定的范围内。
