另外还需要说明的是，在不冲突的情况下，本发明中的实施例及实施例中的标签可以相互组合。下面将参考附图并结合实施例来详细说明本发明。
雾化器可以配合呼吸机使用，对药物进行雾化。传统雾化器在病人吸气和呼气时始终处于工作状态。病人呼气时，雾化的药物无法进入病人的呼吸道，造成药物的浪费。而如果通过气压传感器检测呼吸机的送气和抽气状态，气压传感器直接接入被污染气体管路，会导致气压传感器也受到污染。气压传感器端难以采用常规手段，例如酒精进行浸泡消毒。如果气压传感器单次使用后即抛弃，会提高使用成本，造成极大的浪费。
为了解决上述问题，本发明提出一种管路组件、气压检测模块、雾化系统和呼吸机。
图1示出根据本发明一实施方式的气压检测模块的结构图。
具体地，图1示出了使用气体过滤部件，且气压传感器位于气体过滤部件近端的气压检测模块。
如图1所示，气压检测模块100包括：例如三通管的多通管101和例如滤芯的气体过滤部件103组成的管路组件。气体过滤部件103密闭连接于多通管101的第一路102并位于第一路102中，密封材料106起到气体过滤部件103和多通管101的第一路102间的密闭作用。气体过滤部件103作为污染隔离部件，可以滤除多通管101下段部分中的气体的污染，使得污染无法进入气体过滤部件103的上部。而且，气体过滤部件103允许无污染的气体通过，从而保持气体过滤部件103下侧和上侧的气压相同。
包含多通管101和气体过滤部件103的管路组件受到病菌、病毒等的污染，可以是单次使用组件。
滤芯可以是多孔结构，多孔结构的孔隙为3微米至20微米。滤芯可以是高分子材料或陶瓷材料。滤芯可以是圆柱体或多棱体，优选圆柱体。
多棱体可以为三棱柱，或四棱柱，或其它多棱体。
如图1所示，气压检测模块100还包括：密闭套接于多通管101的第一路102上的密闭空腔104，以及气压感测部件105。气压感测部件105位于密闭空腔104中，用于检测呼吸机管路中的气压变化。气压感测部件105包括气压传感器，通过有线或无线方式输出气压信号。
在如图1的实施例中，密闭空腔104、气压感测部件105可重复使用。
图2示出根据本发明另一实施方式的气压检测模块的结构图。
具体地，图2示出了使用气体过滤部件，且气压传感器位于气体过滤部件远端的气压检测模块。
如图2所示，气压检测模块200包括：例如三通管的多通管201和例如滤芯的气体过滤部件203组成的管路组件。气体过滤部件203密闭连接于多通管201的第一路202并位于第一路202中。气体过滤部件203作为污染隔离部件，可以滤除多通管201下段部分中的气体的污染，使得污染无法进入气体过滤部件203的上部。而且，气体过滤部件203允许无污染的气体通过，从而保持气体过滤部件203下侧和上侧的气压相同。
气管连接件204构成密闭空腔，密闭空腔通过气压传感连接管路（图2中未示出，参考图6中的602）与气压感测部件（图2中未示出，可位于图6的控制模块601中）相连通，用于检测呼吸机管路中的气压变化。气压感测部件包括气压传感器，并输出气压信号，传输至控制模块601。气压信号可采用有线或无线方式传输，优选有线方式，保证短距传输的可靠性。
包含多通管201和气体过滤部件203的管路组件受到病菌、病毒等的污染，可以是单次使用组件。
滤芯可以是多孔结构，多孔结构的孔隙为3微米至20微米。滤芯可以是高分子材料或陶瓷材料。滤芯可以是圆柱体或多棱体，优选圆柱体。
多棱体可以为三棱柱，或四棱柱，或其它多棱体。
在如图2的实施例中，密闭空腔204、气压感测部件可重复使用。
图3示出根据本发明又一实施方式的气压检测模块的结构图。
具体地，图3示出了使用柔性密封部件，且气压传感器位于柔性密封部件近端的气压检测模块。
如图3所示，气压检测模块300包括：例如三通管的多通管301和例如弹性隔膜的柔性密封部件303组成的管路组件。柔性密封部件303密闭连接于多通管301的第一路302的端部。柔性密封部件303作为污染隔离部件，可以完全隔离多通管301下段部分和上段部分，使得下段部分的污染完全无法进入柔性密封部件303的上部。而且，由于柔性密封部件303可以由于气压而产生弹性形变，从而使得柔性密封部件303下部与上部的气压获得传导。
包含多通管301和柔性密封部件303的管路组件受到病菌、病毒等的污染，可以是单次使用组件。
相对于气体过滤部件的方案，采用柔性密封部件作为污染隔离部件能完全隔离病菌、病毒污染物和管道内的其他小粒径气体等污染物；相对于滤芯方案，可以进一步提高隔离、防污效果，提高使用安全性。管道内的小粒径的气体等污染物可以包括：水蒸气、残留的药物成分等。如水蒸气，由于其粒径极小，一般的滤芯无法将其有效阻隔，水蒸气可能透过隔离件，传导至气压感测部件处，水蒸气等可能在这些位置上冷凝，一方面可能会阻塞气压传导的通路，影响气压感测部件的精度，另一方面也会对相关的部件造成腐蚀，影响使用寿命。
但是，由于柔性密封部件本身具有一定的力学特性，其下部的气压经过了柔性密封部件传导后可能会衰减。因此，本发明将柔性密封部件上部的气压与下部的气压的比值定义为气压转换比。本发明优选的实施方式中，旨在进一步提高气压转换比，从而提高气压传感器的测量精度。
柔性密封部件包括：弹性隔膜。弹性隔膜优选为硅胶材质或乳胶材质。经研究发现，为了实现更优的气压转换比，弹性隔膜的弹性模量越小越好。弹性隔膜的形状可以为：圆形或多边形，优选圆形。多边形可以为三角形，或四边形，或五边形，或其它多边形。弹性隔膜为张紧状态或松弛状态，优选张紧状态。张紧状态是弹性隔膜303紧绷在第一路302上，表面完全平整的状态；松弛状态是弹性隔膜303未紧绷在第一路302上，表面具有曲面的状态。弹性隔膜的厚度为0.03毫米至1毫米，优选0.1毫米至0.2毫米。弹性隔膜的形态可以为曲面或平面，优选为平面。优选平面弹性隔膜的好处在于能提高气压转换比。经研究发现，平面形的弹性隔膜在隔膜的两侧具有基本相当参数特性，如：弹性模量等；其能够更线性、准确的传递气压，避免弹性隔膜在回弹和压缩过程中带来的误差，提高气压传导、测量的准确性。
经研究发现，弹性隔膜的直径也是影响气压转换比的重要参数。经研究发现，在一定范围内，弹性隔膜的直径与气压转换比（弹性隔膜两侧的气压比值）呈现正相关的特性，即气压转换比随着弹性隔膜的直径的增大而增大。弹性隔膜的直径的范围为6mm至50mm。优选地，弹性隔膜的直径为8mm至20mm。
图10示出根据本发明一实施方式的弹性隔膜两侧气压的示例性示意图。
本领域普通技术人员可以理解，图10示例性示出了弹性隔膜两侧的气压，而不构成对本发明的限制。
如图10所示，在一个具体的实施方式中（弹性隔膜采用硅胶材质，圆形，0.2毫米厚度，直径12.5毫米），1001是图3、图4所示的弹性隔膜下方的多通管中的气压，1002是经弹性隔膜传导后的，弹性隔膜上方的气压。图10中的横轴是序号，纵轴是气压，气压转换比随着气压的增大而降低。
当气压较低时，气压转换比为1；当气压较高时，气压转换比为0.6。
图11示出根据本发明一实施方式的弹性隔膜的气压转换比的示例性示意图。
本领域普通技术人员可以理解，图11示例性示出了弹性隔膜的气压转换比，而不构成对本发明的限制。
如图11所示，发现，在初始气压值较小的情形下（1000Pa以内），1101示出的气压转换比在1附近，弹性隔膜对气压转换比的影响较小；但随着气压值加大，气压转换比逐渐减小并趋于稳定，气压转换比最低趋近于0.6。
如图3所示，气压检测模块300还包括：密闭套接于多通管301的第一路302上的密闭空腔304，以及气压感测部件305。306是密封材料。气压感测部件305位于密闭空腔304中，用于检测呼吸机管路中的气压变化。气压感测部件305包括气压传感器，并通过有线或无线方式输出气压信号。
在如图3的实施例中，密闭空腔304、气压感测部件305可重复使用。
