Description

患者接口装置和通气治疗设备 技术领域
本发明涉及通气治疗设备领域，具体地涉及一种患者接口装置和包括该患者接口装置的通气治疗设备。
背景技术
非侵入式正压通气的方式已被广泛应用于治疗阻塞性睡眠呼吸暂停(OSA)、慢性阻塞性肺气肿(COPD)等疾病中。其不再需要通过外科手术将管子插入患者的气道中，而是利用鼓风机通过管路以及患者接口装置对患者的气道输送一个持续的压力通气(CPAP)或者变化的压力通气。
非侵入式通气治疗中的患者接口装置通常有鼻氧导管以及鼻面罩、口鼻面罩和全脸面罩等类型的呼吸面罩等。而不管是鼻氧导管还是呼吸面罩，均有一个用于与患者的口和/或鼻连通以向患者供气的气体腔室。在治疗过程中，由于供患者吸入和由患者呼出的气体中都含有水蒸气，水蒸气很容易在气体腔室内冷凝产生冷凝水，而过多的冷凝水会对患者构成潜在威胁。
由于目前市面上的患者接口装置不具备自动去除冷凝水的功能，需要医护人员主动干预，从而使得使用非常不便，同时还增加了医护人员的劳动强度。因此，需要提出一种能够自动去除冷凝水的患者接口装置，以提高通气治疗的安全性，降低医护人员的劳动强度。

具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
在本发明中，在未作相反说明的情况下，使用的方位词如“上、下、顶、底、左、右、后”通常是指患者在站立状态下使用时的方位。“内、外”是指相对于各部件本身轮廓的内外。
本发明一方面提供一种患者接口装置，用于通气治疗设备，所述患者接口装置包括主体10和第一水分导出件20，主体10的内部限定有气体腔室101，气体腔室101用于与患者的口和/或鼻连通，第一水分导出件20安装于主体10并包括与气体腔室101相通的第一部分21和位于主体10外的第二部分22，第一水分导出件20设置为能够通过第一部分21吸收气体腔室101内的水分并将水分传导至第二部分22。
上述中，需要说明的是，第一部分21可通过多种方式与气体腔室101相通，例如，第一部分21可以直接置于气体腔室101内，也可以作为限定气体腔室101的一部分。另外，第一水分导出件20为一体件。气体腔室101内的水分可包括供患者吸入的气体中的水蒸汽、由患者呼出的气体中的水蒸汽以及气体腔室101内产生的冷凝水。
在使用时，第一水分导出件20的第一部分21吸收气体腔室101内的水分后会将水分扩散传导至第二部分22，由于第二部分22位于主体10的 外部环境中，而外部环境湿度较低，相对干燥，第二部分22中的水分会不断蒸发到外部环境中。
本发明的患者接口装置通过在主体10上设置第一水分导出件20，能够将气体腔室101内的水分导出至主体10外，自动去除气体腔室101内的冷凝水，从而提高通气治疗的安全性，降低医护人员的劳动强度。
在本发明中，第一水分导出件20可以是一个额外增设的部件，也可以依附于患者接口装置的其他部件设置。由于在患者接口装置中通常包括有用于将主体10固定于患者头部的头带，因此根据本发明的一种实施方式，第一水分导出件20可形成头带的一部分或者形成整个头带(参见图1-图3)。
由于在患者接口装置佩戴于患者头部时，头带会与患者头部接触，因此为了提高患者佩戴的舒适性，第一水分导出件20可包括固定层叠的吸水层201和防水层202，防水层202靠近头带的用于与患者头部接触的一侧设置。可以理解的是，上述具有防水层202的第一水分导出件20适用于第一水分导出件20与患者头部接触的情况。在其他实施方式中，第一水分导出件20可仅包括吸水层201。
本发明中，第一水分导出件20的防水层202可采用塑料或橡胶等不渗水的材料制成。而为了提高佩戴的舒适性，防水层202最好采用硅胶等较软的材料。第一水分导出件20的吸水层201可采用织物或吸水敷料制成，吸水层201可以是单层或多层结构。另外，当第一部分21用于限定气体腔室101时，位于第一部分21的吸水层最好具有吸水性好但透气阻力较大的特性，这样可以减少供患者吸入气体的损失，提高气体腔室101的密封性。也就是说，第一水分导出件20的第一部分21和第二部分22可采用不同的材料制成。
本发明中，所述患者接口装置可以是鼻氧导管或者鼻面罩、口鼻面罩和全脸面罩等类型的呼吸面罩等。下面以鼻氧导管为例进一步介绍本发明。
如图1所示的鼻氧导管，主体10包括鼻腔连接件11和安装于鼻腔连 接件11的转接头12，第一水分导出件20安装于鼻腔连接件11，气体腔室101由第一部分21、鼻腔连接件11以及转接头12共同限定形成，转接头12能够将来自气源的气体通入气体腔室101。
上述中，可以理解的是，鼻腔连接件11为用于与患者鼻腔连接的部分；气源即为产生加压空气或可呼吸气体的装置，例如可以是通气治疗设备中的主机。另外，鼻腔连接件11可采用柔性材料(例如硅胶)制成，转接头12可采用比鼻腔连接件11硬的材料(例如塑料)制成以对鼻腔连接件11形成支撑，这样能够保证鼻腔连接件11在佩戴舒适的情况下不容易产生变形，从而保证鼻氧导管的通气量，提高鼻氧导管通气的可靠性。
进一步地，如图4和图5所示，鼻腔连接件11可包括用于安装转接头12的安装结构，所述安装结构包括具有底部开口的容置腔以及用于限定所述容置腔的顶壁111和后壁112，第一部分21安装于后壁112的内表面上，转接头12包括具有顶部开口122和后部开口123的壳体121，壳体121经所述安装结构的底部开口密封安装于所述容置腔内，气体腔室101由壳体121、顶壁111以及第一部分21限定形成。上述中，可以理解的是，顶壁111封堵壳体121的顶部开口122，第一部分21封堵壳体121的后部开口123。
上述中，壳体121密封安装于所述容置腔内，意味着壳体121的外壁与顶壁111和后壁112之间没有间隙(参见图5)。进一步地，壳体121与顶壁111和后壁112之间可通过凸缘和凹槽的配合结构进行卡接，从而提高装配可靠性和气密性。具体地，如图4和图5所示，顶壁111上设置有从顶壁111的边缘向下延伸的第一凸缘115，壳体121的外壁上设置有与第一凸缘115配合的第一凹槽125；后壁112上设置有从后壁112的内表面向前延伸的第二凸缘116，壳体121的外壁上设置有与第二凸缘116配合的第二凹槽126。另外，如图5所示，第二凸缘116与顶壁111之间可限定出供第一部分21嵌设的安装槽。
本发明中，在第一水分导出件20形成为头带的情况下，为了加强第一水分导出件20与鼻腔连接件11的连接，如图2所示，鼻腔连接件11可包括分别从后壁112的左右两端向外延伸的两个连接壁114，连接壁114上设置有沿其延伸方向的通孔，第一水分导出件20的第二部分22设置为从第一部分21的一端延伸穿过两个连接壁114后连接于第一部分21的另一端。需要说明的是，在制作时，第一水分导出件20可与鼻腔连接件11一起注塑而成。
另外，如图4和图5所示，鼻腔连接件11还可包括用于插入鼻腔的鼻塞113，鼻塞113设置为从顶壁111向上延伸且与气体腔室101连通。可以理解的是，鼻塞113为两个。
本发明中，如图1所示，转接头12还可包括用于与所述气源的通气管路30连接的接口124，接口124设置在壳体121上且与气体腔室101连通。在使用时，来自气源的气体经通气管路30、接口124进入气体腔室101内，接着经壳体121的顶部开口122由鼻塞113通入使用者鼻腔内。
此外，为了提高转接头12与鼻腔连接件11装配的可靠性，进一步提高所述鼻氧导管的气密性，鼻腔连接件11还可包括用于将转接头12固定于所述安装结构的固定件。
其中，所述固定件可以为两端分别连接于顶壁111和后壁112以形成供转接头12穿设的穿设空间的固定带。具体地，如图1和图2所示，所述固定带可包括沿转接头12的穿设方向(即图2中从左到右的方向)间隔设置的第一固定带117和第二固定带118。壳体121的周向轮廓可设置为沿其穿设方向逐渐减小，相应地，第一固定带117形成的穿设空间大于第二固定带118形成的穿设空间，这样，在转接头12安装于鼻腔连接件11时，壳体121的右端可以很容易地穿过第一固定带117，然后穿设于第二固定带118内，装配非常简单。另外，为了防止转接头12的与第二固定带118配合的一端翘起而产生气体泄漏，可使第二固定带118的远离第一固定带117 的一端形成为封闭状(参见图2)。此时，转接头12只能从第一固定带117的左侧插入固定，而无法从第二固定带118的右侧插入。
本发明另一方面提供一种通气治疗设备，所述通气治疗设备包括以上所述的患者接口装置。
本发明中，所述通气治疗设备可以是呼吸机、高流量治疗仪等。
所述通气治疗设备还可包括作为气源的主机和通气管路30，所述主机可通过通气管路30与所述患者接口装置连接。具体地，当所述患者接口装置为鼻氧导管时，通气管路30的一端可与主机的出气口连接，通气管路30的另一端可与鼻氧导管中转接头12的接口124连接。
本发明中，所述通气治疗设备还可包括第二水分导出件40，第二水分导出件40安装于通气管路30并包括位于通气管路30内的管内部分41和位于通气管路30外的管外部分42，第二水分导出件40设置为能够通过管内部分41吸收通气管路30内的水分并将水分传导至管外部分42。
在使用时，第二水分导出件40的管内部分41吸收通气管路30内的水分后会将水分扩散传导至管外部分42，由于管外部分42位于通气管路30的外部环境中，而外部环境湿度较低，相对干燥，管外部分42中的水分会不断蒸发到外部环境中。
本发明通过在通气管路30上安装第二水分导出件40，所述患者接口装置的气体腔室101内形成的冷凝水可流至通气管路30中，进而由第二水分导出件40导出。
其中，需要说明的是，第二水分导出件40为与第一水分导出件20类似的部件，但由于第二水分导出件40不与患者头部接触，因此第二水分导出件40可只包括吸水层，其可以是采用织物或吸水敷料制成的单层或多层结构。
在一些实施方式中，为了降低患者在使用时的气道干燥等不适感，所述通气治疗设备还可包括用于对气体进行加热湿化的湿化装置，湿化后的 气体可通过通气管路30输送至所述患者接口装置。在这种情况下，第二水分导出件40的设置还可以防止湿化气体在通气管路30中形成过多的冷凝水而进入患者的呼吸道造成潜在的风险。
根据本发明中通气管路30的一种实施方式，如图6所示，通气管路30可包括第一管路31，第二水分导出件40可安装于第一管路31，第二水分导出件40的管内部分41位于第一管路31内，第二水分导出件40的管外部分42位于第一管路31外。
其中，对于第二水分导出件40的安装，如图7所示，可在第一管路31的管壁上设置开口，管内部分41连接于第一管路31的内壁，管外部分42经所述开口密封伸出第一管路31外。其中，第二水分导出件40的管内部分41可通过粘结或热熔焊接的方式固定于第一管路31的内壁，管外部分42可以连接于第一管路31的外壁，也可以不与第一管路31的外壁连接。而为了提高第一管路31的密封性，在制作时，第二水分导出件40优选为与第一管路31通过注塑形成为一体。
本发明中，第二水分导出件40可以具有任意形状。具体地，如图6和图7所示的实施方式，第二水分导出件40可以为沿第一管路31的轴向延伸的长条状，管外部分42连接于第一管路31的外壁。
进一步地，为了提高第一管路31内水分的导出效果，通气管路30可包括多个第二水分导出件40，多个第二水分导出件40可沿第一管路31的周向排布。
以上介绍了通气管路30包括一根管路(即第一管路31)的情况，在本发明的其他实施方式中，通气管路30可由多根管路连接而成，在这种情况下，可分别在每根管路上安装第二水分导出件40，也可在相邻的两根管路上安装第二水分导出件40。
具体地，例如图8所示的实施方式，通气管路30还可包括第二管路32，第二管路32连接于第一管路31的一端，第二水分导出件40的管内部分41 连接于第一管路31的内壁，管外部分42连接于第二管路32的外壁。
进一步地，如图8和图9所示，第二管路32可插接于第一管路31，第二水分导出件40的管外部分42可经第一管路31与第二管路32的插接间隙延伸至第二管路32外。在这种情况下，第二水分导出件40可以为筒状，这样可将管内部分41的外周面连接于第一管路31的内壁，管外部分42则直接套设于第二管路32的外壁上。
上述中，第二管路32可以为加热管路。在这种情况下，由于第二水分导出件40的管外部分42与第二管路32的外壁接触，因此可以加快管外部分42中水分的蒸发，从而提高水分导出效果。在使用时，第一管路31的背离第二管路32的一端可连接于患者接口装置，第二管路32的背离第一管路31的一端可连接于主机。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
