呼吸面罩和通气治疗设备
相关申请的交叉引用
本申请要求享有于2018年12月29日提交的名称为“呼吸面罩和通气治疗设备”的中国专利申请CN201811646330.2的优先权，该申请的全部内容通过引用并入本文中。
技术领域
本发明涉及通气治疗设备领域，具体地涉及一种呼吸面罩和含有该呼吸面罩的通气治疗设备。
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病人的气道中，而是利用鼓风机通过管路以及病人接口装置对病人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病人接口装置通常有鼻面罩、口鼻面罩、鼻枕面罩和全脸面罩等类型的呼吸面罩。呼吸面罩的典型结构包括框架、衬垫、弯管、连接件和头带等部件，衬垫固定在框架上，衬垫与框架一起形成一个气体腔室，弯管通过连接件与框架连接以将治疗气体输送至气体腔室内，头带与患者头部连接以将呼吸面罩固定在患者头部的合适位置上。在使用时衬垫与患者面部接触并实现与面部的密封，患者的口和/或鼻位于气体腔室内。
由于在呼吸面罩的使用过程中，需要将呼吸废气排出面罩外，因此为了使呼吸废气顺利排出，通常会在呼吸面罩上设置排气孔。但是现有呼吸面罩中的排气孔通常开设在弯管或框架上，为了保证排气量，孔径通常较大，导致呼吸面罩的排气噪音较大，而且排出的气体会影响到床伴。
为了解决上述问题，目前有些呼吸面罩采用小孔排气的方式，例如图1和图2所示的呼吸面罩，排气小孔31’成团簇状集中布置在弯管3’(参见图1)或框架1’上(参见图2)。但是由于小孔直径及成型受模具的影响较大，导致制作困难且成本较高；而且由于空间限制，小孔排气的方向仍会使气流吹到床伴， 从而影响患者自身及床伴的睡眠质量。
发明内容
本发明的目的是提供一种呼吸面罩和含有该呼吸面罩的通气治疗设备，以降低呼吸面罩的排气噪音，同时避免排出的气流吹到床伴。

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”通常是指参照附图所示的方位。“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呼吸面罩，所述呼吸面罩包括衬垫组件、弯管组件和设置于所述衬垫组件与所述弯管组件之间的连接组件，所述衬垫组件包括罩杯6，所述连接组件包括框架1和连接件2，所述弯管组件包括弯管3，所述连接件2与所述框架1之间和/或所述罩杯6与所述框架1之间形成有排气通道4，所述排气通道4设置为能够引导呼吸废气向所述弯管3的四周发散排出。
本发明的呼吸面罩通过在连接件2与框架1之间和/或罩杯6与框架1之间设置排气通道4，并将排气通道4设置为引导呼吸废气向弯管3的四周发散排出，使得佩戴该呼吸面罩的患者无论面朝哪个方向，气流都不会吹到床伴，而且由于气流是呈环状发散排出的，能够有效降低排气噪音。
上述中，应当理解的是，例如图3和图6所示，所述衬垫组件还可包括有衬垫5，衬垫5安装于罩杯6的背离框架1的一侧，衬垫5、罩杯6与框架1一起形成一个气体腔室，弯管3通过连接件2与框架1连接以将气体输送至所述气体腔室内，在使用时，衬垫5与患者面部接触并实现与面部的密封，患者的口和 /或鼻位于气体腔室内，因此，排气通道4是与所述气体腔室连通的，患者产生的呼吸废气会先进入所述气体腔室，然后经排气通道4排出。另外，对于呼吸废气向弯管3的四周发散排出，可以理解为呼吸废气沿弯管3的周向并与弯管3的轴向成一定角度排出。上述弯管3的周向和轴向是针对弯管3的与连接件2连接的一端而言的(参见图3和图4)。
其中，需要说明的是，所述连接件2与弯管3可以各自是一单件，所述连接件2与弯管3也可以是一整体。所述连接件2可以由PP(聚丙烯)材质或PC(聚碳酸酯)材质制成。优选的，所述连接件2较所述框架1和/或所述弯管3的刚性较弱，以减小所述弯管3与所述框架1之间的转动异响，增加转动顺畅度。
另外，需要说明的是，如图6所示，罩杯6可包括接口部61，罩杯6可通过接口部61与框架组件连接。当本发明的呼吸面罩选择在罩杯6与框架1之间设置排气通道4时，可将排气通道4设置于接口部61与框架1之间。其中，接口部61可以设置为从罩杯6向框架组件连接侧延伸(参见图6)或从罩杯6向远离框架组件连接侧延伸，优选的，所述接口部61设置为从罩杯6向远离框架组件连接侧延伸以提高接口部61与框架组件之间的连接稳固性，且减小呼吸面罩的体积。
本发明中，对于连接件2与弯管3和框架1的连接，如图5和图6所示的一种实施方式，所述连接件2可具有用于与所述弯管3连接的内壁面21和用于与所述框架1连接的外壁面。根据本发明的一种实施方式，可将所述排气通道4形成在所述外壁面与所述框架1之间。
进一步地，根据本发明中排气通道4的一种实施方式，如图9所示，所述框架1可包括用于安装所述连接件2的安装腔，所述安装腔包括同轴连通的圆柱腔和圆台腔，所述圆台腔靠近所述弯管3设置(即图9所示的下端)，所述圆台腔的直径沿背离所述圆柱腔的方向(即图9所示由上至下的方向)递增，所述框架1还包括用于限定所述圆柱腔的第一壁面11和用于限定所述圆台腔的第二壁面12；如图6、图11和图13所示，所述连接件2的所述外壁面可包括与所述第一壁面11对应的圆柱面22和与所述第二壁面12对应的圆台面23，所述第一壁面11与所述圆柱面22之间、所述第二壁面12与所述圆台面23之间在所述安装腔的径向上均具有间隙，该间隙形成所述排气通道4。其中，可以理解的是，第一壁面11和圆柱面22之间的间隙与第二壁面12和圆台面23之间的间隙是连通 的。所述排气通道4可包括排气前段41和排气后段42，所述第一壁面11与所述圆柱面22之间的间隙形成所述排气前段41，所述第二壁面12与所述圆台面23之间的间隙形成所述排气后段42。在使用时，呼吸废气经所述气体腔室先进入排气前段41，然后进入排气后段42，经排气后段42排出。而由于第二壁面12与圆台面23的结构特征，使得排气后段42形成为围绕弯管3的喇叭状，从而使得呼吸废气沿着弯管3的四周发散排出。
上述中，需要说明的是，依据第一壁面11与第二壁面12、圆柱面22与圆台面23的过渡方式的不同，以及圆台面23的母线与第二壁面12的母线的延伸方向的不同，排气通道4可以具有多种横截面形状，例如图14-图18所示。其中，为了保证呼吸废气流动的连续性、顺滑性，减少流动阻力，降低噪音，可优选为使第一壁面11与第二壁面12通过第一圆弧13过渡连接，使圆柱面22与圆台面23通过第二圆弧24过渡连接(参见图14和图18)。而为了便于排气量的控制，可优选为使排气前段41的宽度大于排气后段42的宽度，例如图14所示。佩戴时，患者面部的近似平行平面可看作S面，排气前段41与患者鼻部相连，由于排气前段41宽度较大，有利于呼吸废气的排出；而排气后段42的宽度较小，有利于控制排气流量，并降低排气噪音。其中，所述圆台腔的母线与所述圆台腔的底面(与S面平行)之间成角度β，为了避免排出气流干扰床伴，β可以为0-75°，优选为10-30°。其中，可以理解的是，通过调节排气后段42的宽度，可以控制排气量，降低噪音；通过调节排气后段42与S面之间的角度，可以实现排气方向的调节。
本发明中，为了提高连接件2与框架1装配的可靠性，降低连接件2装配后的轴向活动自由度，可在所述圆台面23上突出地形成第二凸起231，并使所述第二凸起231的背离所述圆台面23的第二表面设置为与所述第二壁面12抵接；或者在所述第二壁面12上突出地形成第二凸起231，并使所述第二凸起231的背离所述第二壁面12的第二表面设置为与所述圆台面23抵接。也就是说，在排气后段42内设置第二凸起231，第二凸起231支撑于圆台面23与第二壁面12之间，第二凸起231的突出高度则决定了排气后段42的宽度。
其中，为了进一步保证排气量，降低排气噪音，作为优选，可使所述圆台面23的母线与所述圆台腔的母线平行，所述第二凸起231的突出高度(即排气后段42的宽度)可以为0.05-0.6mm，优选为0.05-0.2mm。另外，为了进一步提 升效果，可在所述圆台面23或者所述第二壁面12上设置沿所述圆台面23或者所述第二壁面12的周向间隔排布的多个所述第二凸起231(参见图12)。在这种情况下，多个第二凸起231可将排气后段42分隔为多个扇形通道。
本发明中，所述连接件2可通过卡扣结构与所述框架1连接，所述卡扣结构可包括设置于所述外壁面上的第一卡扣和设置于所述框架1上的与所述第一卡扣配合的第二卡扣。
具体地，根据本发明的一种实施方式，如图6和图7所示，所述第一卡扣为突出地形成在所述圆柱面22上且沿所述圆柱面22的周向延伸的环形凸台221，所述第二卡扣为突出地形成在所述第一壁面11上的第一凸起111，所述连接件2通过所述环形凸台221承靠在所述第一凸起111上。
在装配时，参见图6，可将连接件2的上端从下往上插入框架1的安装腔内，使环形凸台221卡接于第一凸起111的上方(用于承受沿轴向的拉脱力)。为了便于环形凸台221的安装，同时保证环形凸台221不易松脱，所述环形凸台221的宽度可设置为0.1-1mm，优选为0.2-0.6mm。
其中，对于所述第一凸起111，在设置时，可使所述第一凸起111的背离所述第一壁面11的第一表面112设置为与所述圆柱面22抵接，这样第一凸起111可以支撑在第一壁面11与圆柱面22之间，保证连接件2与框架1装配的可靠性，降低连接件2装配后的活动自由度，而且第一凸起111的突出高度可决定排气前段41的宽度。另外，为了实现与环形凸台221的牢固卡接，提高第一凸起111的承压力，利于呼吸废气的排出，如图9所示，可使所述第一凸起111的宽度在所述圆柱腔的轴向上沿朝向所述环形凸台221的方向(即由下至上的方向)逐渐增大，也就是说将第一凸起111设置为上宽下窄的结构，其中第一凸起111的侧面114与竖直方向之间的夹角可以是2-6°。此外，为了使气流在排气前段41与排气后段42之间的光滑过渡，如图9所示，可使所述第一凸起111的背离所述第一壁面11的第一表面112的靠近所述第二壁面12的一端(即第一表面112的下端)延伸至所述第二壁面12并与所述第二壁面12共面。
本发明中，作为优选，所述第一壁面11上可设置有多个所述第一凸起111，多个所述第一凸起111可沿所述第一壁面11的周向间隔排布(参见图8)。需要说明的是，第一凸起111的个数与第二凸起231的个数可以相等，也可以不等。作为优选，第一凸起111的个数与第二凸起231的个数相等，且多个第二凸起 231在所述安装腔的轴向上与多个第一凸起111一一对应，这样可提高连接件2与框架1安装的可靠性，保证受力的均衡，同时还能将整个排气通道4分隔为多个间隔的流动通道。
本发明中，为了防止连接件2相对于框架1旋转，所述呼吸面罩还可包括用于防止所述连接件2相对于所述框架1旋转的防转结构。该防转结构可通过任意方式实现，本发明并不做限制。
根据本发明的一种实施方式，如图10和图11所示，所述防转结构可包括突出地形成在所述圆柱面22上的凸缘222和形成在所述第一凸起111上的供所述凸缘222嵌入的凹槽113。需要说明的是，当框架1包括多个第一凸起111时，凹槽113设置在其中一个第一凸起111上。另外，为了便于在装配过程中凸缘222与凹槽113的配合，可在连接件2上设置标记部27(参见图13)，标记部27的位置在竖直方向上与凸缘222对应。这样可以加快连接件2与框架1的装配速度。
本发明中，对于弯管3与连接件2的连接，如图6所示，弯管3可与连接件2的内壁面21球窝连接。其中，为了避免弯管3从连接件2中脱出，可在连接件2的底面设置第一凸部25；为了提高连接件2的强度，可在连接件2的底面设置第二凸部26。如图6所示，第一凸部25和第二凸部26可设置为沿连接件2的周向延伸，第一凸部25和第二凸部26可分别位于连接件2的底面的内缘和外缘。
本发明另一方面提供一种通气治疗设备，包括用于产生治疗气体的主机和与所述主机的出气口连通的呼吸面罩，该呼吸面罩为以上所述的呼吸面罩。
其中，所述通气治疗设置可以是呼吸机。
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。
