一种面罩组件

本申请要求享有于2015年06月23日提交的名称为“一种面罩组件”的中国专利申请CN201510351032.0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
本发明涉及辅助呼吸设备，特别涉及一种面罩组件。
背景技术
众所周知，面罩组件(或称呼吸面罩)主要应用到各种呼吸道疾病或者睡眠呼吸障碍的连续气道正压通气的治疗中。面罩组件通常需要与呼吸机相连，以便把呼吸机输出的可呼吸的气体提供给佩戴者。
人体通过CPAP面罩不断地从呼吸机吸入空气，同时也在源源不断地向外呼出二氧化碳等气体。面罩作为吸入和呼出气体的场所，将呼出的气体及时排出才能避免二氧化碳的重复吸入。因此，选择合适位置的排气口非常重要。合适位置的排气口有利于二氧化碳的排放，减少二氧化碳的重复吸入，有利于降低噪音，减少气流对同伴的干扰。然而，现有技术中的面罩的进气接口和排气口设置在弯管上，使得面罩主腔体气体内排出的气体不能及时排出，形成所谓的死腔，导致二氧化碳重复吸入；且现有技术中的面罩的进气接口与排气口均设置在弯管上，使得进气接口进入的一部分气体直接从排气口排出，导致一部分需要排出的废气不能顺利排出。废气不能及时排出部分废气被患者重复吸入，因此降低了佩戴者的满意度。
发明内容
本发明所要解决的技术问题是为了克服现有技术中面罩中呼出的废气不能及时顺畅排出的不足。
针对上述问题，本发明提出了一种面罩组件，包括：框架，设置有第一出气口；前额支架，设置有第二出气口；导流件，包括与所述第一出气口配合的第一端、与所述第二出气口配合的第二端以及形成从所述第一端贯通到所述第二端的通道，所述通道连通所述第一出气口与第二出气口。
根据本发明的面罩组件的实施例，其包括框架、前额支架以及导流件。框架上设置有第一出气口。前额支架上设置有第二出气口。导流件上设置有导通第一出气口和第二出气口的通道。这样，框架内的废气可以经过第一出气口、通道以及第二出气口排放到外界环境中。相较于现有技术中将出气口设置于进气弯管上，本发明直接将第一出气口设置于框架上，第一出气口的位置与面罩组件的进气不在同一位置上，从而使得面罩组件的进气与排气形成良性循环，避免了进气流和排气流发生对冲。因此，面罩组件的分开设置进气接口与排气口的有利于二氧化碳的排放，避免了二氧化碳被重复吸入，同时也降低了气流对冲时产生的噪音。且通过导流件将框架的第一出气口与前额支架的第二出气口连通，将从第一出气口流出的气体从前额支架的第二出气口排出，能够避免从第一出气口流出的气体直吹前额支架，延长气体流出路径，降低气体排出的噪声。
在一个实施例中，所述框架上设置有进气接口，所述第一出气口的轴线与所述进气接口的轴线之间形成有夹角。
在一个实施例中，所述框架包括第一连接部，所述前额支架包括与所述第一连接部铰接的第二连接部。
在一个实施例中，所述第一连接部为所述进气接口，所述第二连接部包括固定设置于所述前额支架上的连接套，所述连接套套设于所述进气接口内且与所述进气接口球铰接。

根据本发明的面罩组件的实施例，其包括框架、前额支架以及导流件。框架上设置有第一出气口。前额支架上设置有第二出气口。导流件上设置有导通第一出气口和第二出气口的通道。这样，框架内的废气可以经过第一出气口、通道以及第二出气口排放到外界环境中。相较于现有技术中将出气口设置于进气弯管上，本发明直接将第一出气口设置于框架上，第一出气口的位置与面罩组件的进气不在同一位置上，从而使得面罩组件的进气与排气形成良性循环，避免了进气流和排气流发生对冲。因此，面罩组件的分开设置进气接口与排气口的有利于二氧化碳的排放，避免了二氧化碳被重复吸入，同时也降低了气流对冲时产生的噪音。且通过导流件将框架的第一出气口与前额支架的第二出气口连通，将从第一出气口流出的气体从前额支架的第二出气口排出，能够避免从第一出气口流出的气体直吹前额支架，延长气体流出路径，降低气体排出的噪声。
导流件通过设置在前额支架上的安装孔连接到一起时，导流件不会从前额支架上脱离开，防止导流件的意外丢失。导流件与前额支架和框架通过可拆卸地固定连接到一起时，佩戴者可以定期地将导流件拆卸下来进行清洗消毒。

具体实施方式
下面将结合附图对本发明作进一步说明。
如图1所示，本发明的面罩组件的实施例，其包括框架以及可摆动地设置于框架上的前额支架12。框架包括衬垫113以及与衬垫113相连接的框架主体11。框架主体11与衬垫113可以分体设置，通过卡接、粘接等方式连接；也可以通过二次包胶一体成型。衬垫113使用柔性材料加工制造，以使其更好更舒适地和人的皮肤接触，同时也会与人的皮肤贴合良好，保证气密性。框架主体11还包括进气接口112。框架主体11上靠近进气接口112的位置设置有第一出气口111。框架主体11的内部环境通过第一出气口111与外部环境相连通。第一出气口111的轴线与进气接口112的轴线之间形成有夹角。前额支架12包括与框架主体11相连接的安装部、与前额贴合的贴合部以及连接安装部与贴合部的中间部。前额支架12的中间部上设置有第二出气口121。第二出气口121作为面罩组件的排气口，框架主体11内部的气体最终会从第二出气口121处排放到大气环境中。
在第一出气口111与第二出气口121之间设置有导流件15。导流件15包括与第一出气口111配合的第一端、与第二出气口121配合的第二端以及形成从第 一端贯通到第二端的通道155。在一个实施例中，第一端的端面可以直接粘接到框架主体11上，通道155与第一出气口111完全连通。第二端的端面可以直接粘接到前额支架12朝向框架主体11的表面上，通道155与第二出气口121完全连通。这样，佩戴者佩戴该面罩组件时，佩戴者呼出的气体可以通过第一出气口111、通道155以及第二出气口121排放到大气环境中。
第一出气口111、通道155以及第二出气口121形成的排气通道不再与弯管组件13的进气通道发生重叠。由于第一出气口111的轴线与进气接口112的轴线形成有夹角，因此，面罩组件的排气方向98与进气方向99之间也形成夹角α(如图13所示)。一般地，夹角α在30°至60°之间；以使佩戴者佩戴本发明的面罩组件时，从前额支架12处排出的气流不会与从弯管进入的气流发生对冲，利于废气的排放。排气方向98与进气方向99形成大致45度角时，使得气体朝斜上方吹出，能最大程度地减少气流对同伴的干扰。因此，设置在前额支架12上的排气口有利于二氧化碳的排放，避免了二氧化碳被重复吸入，同时也降低了气流对冲时产生的噪音，减少气流对他人的影响。
框架主体11包括第一连接部。前额支架12上设置有与第一连接部铰接的第二连接部。
本实施例中，第一连接部包括框架主体11上的进气接口112。前额支架12的安装部上设置有连接通孔。第二连接部包括套设于连接通孔的连接套。连接套的一端与进气接口112球铰接。如图2、图3所示，与框架主体11进气接口112球铰接且与前额支架12的连接通孔固定连接的连接套是球形转轴14。球形转轴14上设置有两个平行的平整面141。球形转轴14的平整面141与框架主体11的进气接口112内表面上设置的内平整面1121相配合后，球形转轴14只可以在进气接口112中摆动。
在其他的实施例中，第一连接部和第二连接部枢接连接。例如，第一连接部为设置于框架主体上的第一支撑架，第一支撑架上设置有第一安装孔。第二连接部为设置在前额支架的中间部的第二支撑架。第二支撑架上设置有与第一安装孔对应的第二安装孔。第一安装孔和第二安装孔通过枢轴连接。
本实施例中，导流件15是自身具有弹性变形特性的弹性件，受到外力时会发生变形，撤去外力后又可回复原状。这样，当促动与球形转轴14相连接的前额支架12时，前额支架12可以发生摆动，并对导流件15施加应力。
当前额支架12朝靠近佩戴者前额的方向进行摆动时，前额支架12会压缩导流件15使其发生弹性变形。导流件15变形后，通道155依然保持畅通，不影响气流从导流件15通过。可摆动的前额支架12可以调节到佩戴者前额的距离，满足了不同佩戴者的不同前额高度的佩戴需求。另外，前额支架12的中间部设置的第二出气口121形成的排气口限制了排气方向98。在佩戴者佩戴该面罩组件时，排气方向98是朝向斜上方的，排放气流不再正对着位于佩戴者前方的同伴等旁人，减少了排出气流对同伴等旁人的干扰，提升了佩戴的舒适度。
在一个实施例中，导流件15的两端采用粘接的方式分别与前额支架12和框架主体11粘接在一起，以此保证通道155、第一出气口111和第二出气口121相连通。这样的安装方式快速方便，不用对前额支架12、导流件15和框架主体11进行过多的加工。本实施例中，第二出气口121是筛孔16。筛孔16是锥形孔，朝向大气环境一侧的孔径小于朝向通道155一侧的孔径。
在一个实施例中，如图4所示，第二出气口121是筛孔16。筛孔16是锥形孔，朝向大气环境一侧的孔径小于朝向通道155一侧的孔径。前额支架12上还设置有围绕全部筛孔16的安装孔122。安装孔122围绕全部的筛孔16沿周向均匀分布。
导流件15的第二端通过安装孔122连接到前额支架12。导流件15的第二端包括第一固定部151、第二固定部152以及第三固定部153。连接过程是，首先在前额支架12上加工好筛孔16和安装孔122，然后采用包胶工艺加工出导流件15。导流件15的第一固定部151位于前额支架12的外侧，第二固定部152位于前额支架12的内侧。安装孔122中填充有导流件15的第三固定部153，第一固定部151和第二固定部152都与第三固定部153连接为一个整体。这样，如图6、图7所示，完成包胶工艺后，导流件15就与前额支架12形成为一个整体，不能从前额支架12被拆卸下来，除非对导流件15进行破坏式拆卸。导流件15在变形过程中不会脱离与第二出气口121的配合，这样导流件15也不容易丢失。
在一个实施例中，导流件15的第一端可以采用粘接的连接方式与框架主体11固定连接。另外，如图5所示，可以在导流件15第一端的端部外周表面上设置第一周向槽154。如图7所示，用力将导流件15的第一端插入到第一出气口111内，让第一周向槽154卡接到框架主体11的外壁上以实现导流件15与框架主体11的连接。优选地，第一周向槽154内涂覆粘接剂，在第一周向槽154与 框架主体11的外壁卡接后，粘接剂会将外壁与第一周向槽154的表面粘接起来。这样，第一端的端部与外壁实现固定连接，导流件15发生变形时也不会使第一端的端部发生变形而导致第一端的端部脱离与外壁的固定连接。第一端的端部与外壁完成粘接后，也保证了该处的气密性，使气流不会从第一周向槽154与外壁表面之间的间隙处泄露。
在一个实施例中，如图8所示，通道155靠近导流件15第二端的部分设置为筛孔16。筛孔16是锥形孔，朝向大气环境一侧的孔径小于朝向通道155一侧的孔径。筛孔16设置在导流件15上相对于设置在前额支架12上更容易加工制造。第二出气口121被构造为容纳第二端的端部的通孔。这样，第二出气口121被构造为通孔相对于被构造为筛孔16更方便加工制造。
导流件15上设置有筛孔16的第二端与第二出气口121相配合。第二端可以插入到第二出气口121并通过粘接方式与前额支架12形成固定连接。在一个实施例中，如图8、图9所示，第二端也可以设置第二周向槽156。第二出气口121的内表面上设置有与第二周向槽156相配合的凸起。优选地，凸起与第二周向槽156以粘接的连接方式实现固定连接，保证固定连接的稳定牢靠。导流件15的第一端可以采用粘接的连接方式与框架主体11固定连接。另外，导流件15的第一端的端部插入到第一出气口111中并通过设置在端部外周表面的第一周向槽154与框架主体11的外壁粘接在一起来实现固定连接，保证该处的气密性和固定连接的稳定牢靠。
在一个实施例中，如图10、图11所示，第二出气口121设置为筛孔16。筛孔16是锥形孔，朝向大气环境一侧的孔径小于朝向通道155一侧的孔径。前额支架12上设置有朝向框架主体11延伸的凸柱123。凸柱123为中空，即设置有中心孔。中心孔与所有的筛孔16相连通。凸柱123的顶端(远离前额支架12表面的那一端)的端部上设置有周向凸缘124。
如图12所示，通道155靠近导流件15的第二端的内表面上设置有与周向凸缘124相配合的卡接槽157。凸柱123插入到通道155后，周向凸缘124就卡入到卡接槽157中以实现导流件15与前额支架12的连接。优选地，周向凸缘124与卡接槽157采用粘接的连接方式实现固定连接，保证气密性和固定连接的稳定牢靠。导流件15的第一端可以采用粘接的连接方式与框架主体11固定连接。另外，导流件15的第一端的端部插入到第一出气口111中并通过设置在外周表面 的第一周向槽154与框架主体11的外壁粘接在一起实现固定连接，保证该处的气密性和固定连接的稳定牢靠。
可选地，导流件15的通道155是阶梯孔。中间的孔径最大且中部的壁厚相对两端较薄。这样，当导流件15在受到压缩时，中部更容易发生变形。导流件15可以使用硅胶、橡胶等材料加工制造而成。
可选地，以上实施例的导流件15是弹垫。加工制造弹垫的材料包括橡胶或者硅胶材料。
本发明的面罩组件的实施例，包括框架主体11上设置的第一出气口111、前额支架12上设置的第二出气口121以及连接前额支架12与框架主体11的导流件。由第一出气口111、导流件的通道155以及第二出气口121形成的排气通道的排气方向98与框架主体11的进气接口112的轴线100形成一个夹角，即排气方向98与进气方向99形成的夹角α(如图13所示)，该夹角α的范围是40度至60度。优选地，该夹角的角度是45度。这样，排气通道不会与弯管的进气通道重叠。
在佩戴者佩戴本发明的面罩组件时，从前额支架12处排出的气流不会与从弯管进入的气流发生对冲。因此，排气口设置在前额支架12上有利于二氧化碳的排放，避免了二氧化碳被重复吸入，同时也降低了气流对冲时产生的噪音。另外，佩戴本发明的面罩组件时，排气通道的排气方向98朝向斜上方，排放气流不再正对着位于佩戴者前方的同伴等旁人，减少了排出气流对同伴等旁人的干扰，提升了佩戴的舒适度。从而，可摆动的前额支架12可以满足不同佩戴者的不同前额高度的佩戴需求。
虽然已经参考优选实施例对本发明进行了描述，但在不脱离本发明的范围的情况下，可以对其进行各种改进并且可以用等效物替换其中的部件。尤其是，只要不存在结构冲突，各个实施例中所提到的各项技术特征均可以任意方式组合起来。本发明并不局限于文中公开的特定实施例，而是包括落入权利要求的范围内的所有技术方案。
