本申请要求享有于2014年09月01日提交的名称为“一种用于呼吸面罩的框架及包括其的呼吸面罩”的中国专利申请CN2014205006207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
本发明涉及呼吸面罩技术领域，尤其涉及一种用于呼吸面罩的框架及包括其的呼吸面罩。
背景技术
呼吸面罩通常需要佩戴者长期佩戴，佩戴的舒适性是衡量该呼吸面罩产品的性能好坏的标准之一。为了缓解呼吸面罩的衬垫给佩戴者面部施加的压迫感，人们通常会固定设置个与衬垫相连的前额支撑架。但是，由于佩戴者的人种、年龄和身高各不相同，使得不同的佩戴者需要的前额支撑架的尺寸也各不相同。
中国专利CN101472637A公开了一种面罩的前额支架，该前额支架包括框架连接器和前额软垫支架以及调节旋钮，通过旋转调节旋钮可以调整前额软垫支架相对于框架连接器的伸出距离，以便使其适应不同的佩戴者。虽然该面罩的前额支架能够在缓解衬垫给佩戴者面部施加的压迫感的同时适应不同的佩戴者，但是由于其调节旋钮需要手动调节，不同的患者都需要重新调整，而且手动调节难以调节到最佳舒服度，导致操作复杂。另外，其结构也相对复杂，制造工艺要求较高，生产成本偏高。
发明内容
为了解决上述问题，本发明的目的是提供一种用于呼吸面罩的框架及包括其的呼吸面罩，其可以实现前额支撑架的自动调节，而无需人工辅助调节。
根据本发明，提供了一种用于呼吸面罩的框架，其包括前额支撑架、固定架 和连接前额支撑架和固定架的连接件，前额支撑架构造成能够以连接件为支点朝向或背向患者前额摆动。
在一个实施例中，前额支撑架包括设在呼吸面罩的接收罩上的用于接合佩戴者前额的支架，以及设置在支架的顶端的用于安装呼吸面罩的头带的第一连接结构。同时，固定架包括固定设置在呼吸面罩的接收罩上的固定结构和分别设在固定结构的两侧用于安装呼吸面罩的头带的第二连接结构。
在一个实施例中，前额支撑架还包括套接在呼吸面罩的接收罩外的环套，支架通过环套设置在接收罩上。
在一个实施例中，第一连接结构为双钩状结构，第二连接结构均为钩状结构，固定结构为能够固定式套接在接收罩外的固定套。
在一个实施例中，连接件的轴向截面为倒置的M形。
在一个实施例中，M形的弯曲部分薄于其他部分。
在一个实施例中，在连接件的内部设有多个沿着轴向彼此间隔开的增韧腔。
在一个实施例中，前额支撑架和固定架均由树脂材料制成，而连接件可由树脂、橡胶或硅胶材料制成。
在一个实施例中，连接件处于前额支撑架和固定架的底端。
根据本发明的第二方面，提供了一种呼吸面罩，其包括根据本发明第一方面所述的框架。
在本申请中，所述的轴向定义为垂直于佩戴者面部的方向，也可以理解成接收罩或接收罩的通孔的轴向。
根据本发明的用于呼吸面罩的框架通过朝向患者前额或背向患者前额摆动前额支撑架就可以实现前额支撑架的自动调节，而无需人工辅助调节。
同时，根据本发明的用于呼吸面罩的框架通过前额支撑架来分担来自头带的作用力，从而降低由头带施加给接收罩的作用力，因此可以有效地缓解由接收罩给施加佩戴者的面部的压迫感。
另外，根据本发明的用于呼吸面罩的框架相比于现有的呼吸面罩的框架，尤其是中国专利CN101472637A公开的前额支架，具有更加简单结构，因此可以降低制造工艺和制造成本。

在附图中，相同的部件使用相同的附图标记。附图并未按照实际的比例绘制。
具体实施方式
下面将结合附图对本发明作进一步说明。
图1显示了根据本发明的用于呼吸面罩的框架5的安装图。如图1和2所示，该框架5包括前额支撑架501和固定架502，以及连接前额支撑架501和固定架502的连接件503。连接件503可从前额支撑架501和固定架502的顶端、底端以及侧面处连接前额支撑架501和固定架502，前额支撑架501能够以连接件503为支点朝向或背向患者前额进行摆动，则当患者佩戴好具有该框架的呼吸面罩后，前额支撑架501可根据患者的前额高度以连接件503为支点摆动，从而实现前额支撑架501的自动调节。
根据本发明，前额支撑架501和固定架502均由树脂材料制成，而连接件503可由树脂、橡胶或硅胶材料制成。所述的接收罩2可选为呼吸面罩的衬垫，所述衬垫属于本领域技术人员熟知的，在此不作详细描述。
在一实施例中，如图1和图2所示，连接件503设在前额支撑架501和固定架502的底端，以便允许前额支撑架501具有更大的摆动角度。固定架502固定在呼吸面罩的接收罩2上，当佩戴者把接收罩2接合到佩戴者嘴部和/或鼻部后，前额支撑架501会与佩戴者的前额相接触。由于不同的佩戴者的前额的凸出高度不同，前额支撑架501与接收罩2之间的设定角度未必适用所有佩戴者，因此当前额支撑架501顶抵到前额时，需要朝向佩戴者前额或背向佩戴者前额摆动前额支撑架501，以使其适用于不同的佩戴者。具体地说，当所需的前额支撑架501 与接收罩2之间的角度大于设定角度(即佩戴者的前额较凸出)时，前额将促动前额支撑架501扩大该设定角度；当所需的前额支撑架501与接收罩2之间的角度小于设定角度(即佩戴者的前额较低)时，头带将促动前额支撑架501缩减该设定角度。由此可知，本发明的框架5可以实现前额支撑架501的自动调节，而无需人工辅助调节。其中，在前额支撑架501相对于固定架502发生摆动的时候，连接件503相当于合页，以允许前额支撑架501与固定架502发生相对摆动。
接收罩2优选为带有褶皱变形部203的衬垫。如图1所示，该接收罩2可包括适用于接合佩戴者嘴部和/或鼻部的接收罩201和用于连接呼吸管道3的连接部202，以及衔接该接收罩201和连接部202的褶皱变形部203。该褶皱变形部203内的褶皱可构造成波纹管状、锯齿状、沿着接收罩2的外壁呈弧形分布的凹陷状或沿着接收罩2的外壁呈弧形分布的凸起状，当然本领域技术人员也可以根据具体需求构造成其它形状。前额支撑架501和固定架502分别处于该褶皱变形部203的两侧，即前额支撑架501处于连接部202上，而固定架502处于接收罩201上。通过这种方式，可以利用褶皱变形部203容易变形的特点，减少该框架5在实现自动调整前额支撑架501时由褶皱变形部203施加给上述摆动的阻力。
在另一实施例中，连接件503设在前额支撑架501的底端和固定架502的顶端，固定架502固定在接收罩上，前额支撑架501可根据患者的前额高度以连接件503为支点朝向或背向患者摆动。
根据本发明，前额支撑架501可包括设在呼吸面罩的接收罩2上的用于接合佩戴者前额的支架501b，以及设置在支架501b的顶端的用于安装呼吸面罩的头带的第一连接结构501c，请参见图2。该第一连接结构501c为双钩状结构，以用于快速、可拆卸地安装呼吸面罩10的头带。在图1和图2所示的实施例中，前额支撑架501还包括套接在呼吸面罩的接收罩2外的环套501a，支架501b通过环套501a设置在接收罩2上。其中，环套501a的配合面与接收罩2的配合面具有相同形状。环套501a在前额的支架501b的摆动过程中可以分散接收罩2的受力，从而提高接收罩2的使用寿命。
固定架502可包括固定式设置在接收罩2外的固定结构502a。如图1和图2所示，固定结构502a优选为能够固定式套接在接收罩2外的固定套。该固定套与接收罩2的配合面具有相同形状。该固定套可通过设置在接收罩2上的环形凸缘和多个定位凸起201b来固定。除此之外，固定套也可由图6所示的U形结构替 换，该U形结构可被扣套201c固定于接收罩2上。固定架502还可包括分别设在固定结构502a的两侧用于安装呼吸面罩的头带的第二连接结构502b。各第二连接结构502b均优选为钩状结构，以用于快速、可拆卸地安装呼吸面罩10的头带。其中，所述的头带属于本领域技术人员熟知的，在此不再赘述。
为了增强连接件503的性能，连接件503的轴向截面(即同时垂直于佩戴者面部和垂直于佩戴者嘴部的截面)为倒置的M形(见图3)。在前额支撑架501与固定架502发生相对摆动时，这种形状的连接件503能够缩减由连接件503施加给上述摆动的阻力，以便前额支撑架501相对于固定架502的摆动更加顺畅。优选地，M形的弯曲部分503a构造成薄于其他部分，由此可以进一步地缩减由连接件503施加给上述摆动的阻力。除此之外，在连接件503的内部可设有多个沿着轴向彼此间隔开的增韧腔503b(见图4和5)。该增韧腔503b也可以缩减由连接件503施加给上述摆动的阻力，以便前额支撑架501相对于固定架502的摆动更加顺畅。在一个优选的实施例中，各增韧腔503b的大小相同，均垂直于轴向。由此，可以均匀分配连接件503在摆动过程中所受的力，以便加强该连接件503的使用寿命。
根据本发明的用于呼吸面罩的框架5可以实现前额支撑架501的自动调节，而无需人工辅助调节。同时，根据本发明的用于呼吸面罩的框架5通过前额支撑架501来分担来自头带的作用力，从而降低由头带施加给接收罩2的作用力，因此可以有效地缓解由接收罩2给施加佩戴者的面部的压迫感。另外，根据本发明的用于呼吸面罩的框架5相比于现有的呼吸面罩的具有更加简单结构，因此可以降低制造工艺和制造成本。
除上述框架外，本发明还提供了一种呼吸面罩，呼吸面罩包括上述的框架5。
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。
