通气降噪壳体和组件、通气保湿装置、呼吸面罩组件和呼吸支持设备
相关申请的交叉引用
本申请要求在2021年04月13日提交中国专利局、申请号为202120745619.0、名称为“通气降噪壳体和组件、通气保湿装置、呼吸面罩组件和呼吸支持设备”的中国专利公开的优先权，其全部内容通过引用结合在本申请中。
技术领域
本公开涉及医疗器械技术领域，具体地涉及一种通气降噪壳体，一种通气降噪组件，一种通气保湿装置，一种呼吸面罩组件和一种呼吸支持设备。
背景技术
目前，面罩呼吸系统包括呼吸机、呼吸管和呼吸面罩，呼吸面罩包括呼吸腔，该呼吸腔可以容纳使用者的鼻部或鼻部和口部，然后通过头带固定在病人的面部，以形成一个密封的呼吸腔，这样，呼吸管可以将呼吸机产生的可呼吸气体传送至密封的呼吸腔中，进而对使用者的进行呼吸治疗。另外，为了便于使用者的呼出的废气排出，呼吸面罩上通常设置有排气口，这样，呼出的废气即可通过排气孔排出。呼出的废气在通过排气孔时会冲刷气孔侧壁而产生噪声。
为此，一层滤棉在排气孔的外部紧贴排气孔布置，这样，排气孔排出的废气只能通过滤棉排出，滤棉对呼出的废气起到减缓作用，从而有效减小这种噪声。但同时会引入新的风险，由于滤棉的过滤作用，即长时间使用且不按要求清洁时，灰尘将在排气孔处聚集，使得排气孔的流量值会减小，如果不及时清理则会堵塞排气孔，增加了使用风险，使得治疗达不到所期待的效果。
另外，在实际使用中，这种呼吸治疗时间通常比较长，例如使用者经常需要整天、整夜佩戴呼吸面罩。在空气温度较低，空气干燥时，长时间佩戴 呼吸面罩将会降低佩戴舒适度。为此，呼吸机上通常设置有加热加湿装置例如水罐或加湿器，气体经过水罐或加湿器时会携带一部分水汽以向使用者提供加热加湿的可呼吸气体。但是，呼吸机通常体积相对较大，不易携带。
基于此，提出本公开的方案。
概述

如上所述的，该通气降噪组件在实际使用中，由于支撑凸起结构支撑通气降噪芯体，以让通气降噪芯体和通气降噪单元安装壁段的外表面之间至少部分保持通气缝隙，当呼出废气从排气孔排出时，由于通气缝隙的存在，呼出废气会通过通气缝隙和通气降噪芯体从通气开口处排出到外部，由于通气 降噪芯体对呼出废气的减缓作用，从而降低呼出废气冲刷排气口产生的噪音，提升静音效果，同时，呼出废气中携带的杂质例如灰尘的一小部分会在通气降噪芯体上聚集，而大部分的杂质将随着呼出废气顺畅通过通气缝隙以从通气开口处排出到外部或者在远离排气口的位置处聚集，从而不会堵塞排气口，进而降低使用者的使用风险，提升了卫生性，以提升治疗效果。

在该技术方案中，由于通气降噪单元安装壁段4设置有排气口5和从通气降噪单元安装壁段4的外表面上伸出的支撑凸起结构，而支撑凸起结构用于对设置在通气降噪单元安装壁段4上的通气降噪单元6的通气降噪芯体7支撑以使得通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，这样，该通气降噪壳体14在实际使用中，通气降噪单元6可以设置在通气降噪单元安装壁段4上，此时，支撑凸起结构则支撑通气降 噪芯体7，以让通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，当呼出废气从排气口5排出时，由于通气缝隙8的存在，呼出废气会通过通气缝隙8和通气降噪芯体7排出到通气降噪单元6的外部，呼出废气的流动可以参见图4中的箭头示意的，由于通气降噪芯体7对呼出废气的减缓作用，从而降低呼出废气冲刷排气口5产生的噪音，提升静音效果，同时，呼出废气中携带的杂质例如灰尘的一小部分会在通气降噪芯体7上聚集，而大部分的杂质将随着呼出废气顺畅通过通气缝隙8以排出到通气降噪单元6的外部或者在远离排气口5的位置处聚集，从而不会堵塞排气口5，进而降低使用者的使用风险，提升了卫生性，以提升治疗效果。
排气口5的数量可以为一个，或者可以为多个，多个排气口5可以在周向方向仅布置在通气降噪单元安装壁段4的一段周向壁上例如半段周向壁，或者可以在通气降噪单元安装壁段4的一圈周向壁上。
在该通气降噪壳体14中，支撑凸起结构可以设置在通气降噪单元安装壁段4的外表面的任何位置处，其只要能够对设置在通气降噪单元安装壁段4上的通气降噪单元6的通气降噪芯体7支撑以使得通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8即可。例如，支撑凸起结构可以设置在远离排气口5的位置处。或者，支撑凸起结构靠近排气口5设置，这样，对于材质较为柔软的通气降噪芯体7，靠近排气口5的支撑凸起结构更易于对通气降噪芯体7支撑，以避免通气降噪芯体7覆盖所有的排气口5，例如，在排气口5为多个时，可以避免通气降噪芯体7止挡其中的一些排气口5。
另外，在该通气降噪壳体14中，通气降噪单元安装壁段4可以具有多种形状，但不论通气降噪单元安装壁段4采用何种形状，其只要形成有排气口5和支撑凸起结构，并能够安装通气降噪单元6即可。例如，一种结构形式中，通气降噪单元安装壁段4包括轴向延伸的轴向壁，该轴向壁上形成有排气口并伸出有支撑凸起结构，而通气降噪单元6则可以安装在该轴向壁的外表面上。或者，参考图1-图4，通气降噪单元安装壁段4包括径向向外延伸的端面壁9，排气口5和支撑凸起结构形成在端面壁9上，这样，由于端面壁9径向向外延伸，因此，呼出废气沿着呼吸通道段1流动时，更易于顺着轴向 方向从排气口5排出。而参考图3和图4，端面壁9则可以向通气降噪芯体7提供径向向外延伸的安装台阶，从而提升通气降噪芯体7设置在该安装台阶上的可靠性。或者，通气降噪单元安装壁段4包括轴向向外倾斜的倾斜壁，排气口5和支撑凸起结构形成在端面壁9上。
另外，参考图1和图2，支撑凸起结构的径向外端的上表面和前端面之间具有倾斜面29，也就是，将支撑凸起结构的径向外端在上表面和前端面之间切除一部分，从而形成倾斜面29，而径向外端被切除后形成的这部分空间，可以用来容纳通气降噪芯体7，从而增大了通气降噪芯体7容纳空间。这样，参考图3和图4，通气降噪芯体7被支撑凸起结构支撑时，通气降噪芯体7的一部分将被弯曲而容纳在该容纳空间内，或者，通气降噪芯体7自身弯曲的一部分可以容纳在该容纳空间内。
另外，在该通气降噪壳体14中，支撑凸起结构可以具有多种形状，但需要说明的时，支撑凸起结构不论采用何种形状，其只要能够对通气降噪芯体7支撑，使得通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8即可。例如，支撑凸起结构的第一种形状中，支撑凸起结构可以包括第一环凸板和第二环凸板，第一环凸板和第二环凸板可以轴向间隔布置，或者，第一环凸板在径向方向间隔位于第二环凸板的外部，而排气口5位于第一环凸板和第二环凸板之间，通气降噪芯体7可以被第一环凸板和第二环凸板支撑以与通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，第一环凸板和第二环凸板上分别形成有通气缺口，这样从排气口5排出的呼出废气的一部分可以从通气降噪芯体7排出，呼出废气的另一部分从通气缺口流入到通气缝隙8。第一环凸板和第二环凸板可以设置在前述的轴向壁上、端面壁9或者轴向向外倾斜的倾斜壁上。
再例如，支撑凸起结构的第二种形状中，参考图1和图2，支撑凸起结构包括多个周向间隔布置的径向延伸凸筋10，相邻的径向延伸凸筋10之间布置有多个周向间隔的排气口5，这样，通气降噪芯体7可以被多个径向延伸凸筋10支撑以与通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，同时，径向延伸凸筋10可以将其两侧的排气口5隔开，使得从两个径向延伸凸筋10之间的多个排气口5排出的呼出废气快速通过通气缝隙8，这可 以将呼出废气中携带的杂质更快地带走，以避免在排气口5处聚集。
多个径向延伸凸筋10可以设置在前述的轴向壁上、端面壁9或者轴向向外倾斜的倾斜壁上。多个径向延伸凸筋10可以靠近排气口布置。多个径向延伸凸筋10的径向外端的上表面和前端面之间可以具有倾斜面29。
再例如，支撑凸起结构的第三种形状中，参考图1，多个排气口5周向间隔，支撑凸起结构包括多个间隔的周向凸起12，多个周向凸起12位于排气口5的径向外侧，这样，通气降噪芯体7可以被多个周向凸起12支撑以与通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8。周向间隔的多个周向凸起12可以将通气降噪芯体7整个支撑托起，以增加通气缝隙8，进一步避免堵塞排气口5，提高安全性。多个周向凸起12可以设置在端面壁9或者轴向向外倾斜的倾斜壁上。多个周向凸起12可以靠近排气口布置。多个周向凸起12的径向外端的上表面和前端面之间可以具有倾斜面29。
再例如，支撑凸起结构的第四种形状中，参考图1，支撑凸起结构包括多个周向间隔布置的径向延伸凸筋10和多个周向间隔的凸起组11，其中，相邻的径向延伸凸筋10之间布置有周向间隔的排气口5；多个凸起组11位于排气口5的径向外侧，相邻的径向延伸凸筋10之间布置一个凸起组11，每个凸起组11包括多个间隔的周向凸起12。这样，通气降噪芯体7可以被多个径向延伸凸筋10和多个周向凸起12支撑以与通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，同时，径向延伸凸筋10可以将其两侧的排气口5隔开，使得从两个径向延伸凸筋10之间的多个排气口5排出的呼出废气快速通过通气缝隙8，这可以将呼出废气中携带的杂质更快地带走，以避免在排气口5处聚集。周向间隔的多个凸起组11的多个周向凸起12可以进一步将通气降噪芯体7整个支撑托起，以增加通气缝隙8，进一步避免堵塞排气口5，提高安全性。
再例如，支撑凸起结构的第五种形状中，参考图2，支撑凸起结构包括多个周向凸筋段段13和多个周向间隔布置的径向延伸凸筋10，其中，相邻的径向延伸凸筋10之间布置有周向间隔的排气口5，相邻的径向延伸凸筋10之间布置有一个周向凸筋段13，周向凸筋段段13位于排气口5的径向外侧，周向凸筋段13与其周向两端的径向延伸凸筋10保持间隔。这样，通气降噪芯 体7可以被多个径向延伸凸筋10和多个周向凸筋段13支撑以与通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，同时，径向延伸凸筋10可以将其两侧的排气口5隔开，使得从两个径向延伸凸筋10之间的多个排气口5排出的呼出废气快速通过通气缝隙8，这可以将呼出废气中携带的杂质更快地带走，以避免在排气口5处聚集。另外，周向凸筋段13可以将通气降噪芯体7整个支撑托起，以增加通气缝隙8，进一步避免堵塞排气口5，提高安全性。
另外，通气降噪壳体14可以为PP、PC、尼龙或聚碳酸酯PC，优选地，为PC材料。通气降噪壳体14的壳体壁厚为1-3mm，优选1.5mm。排气口5的内部尺寸例如直径为0.5-1.5mm，优选0.8mm。当排气口5为多个时，排气口5之间的口间距为2-8mm，优选4mm。另外，径向延伸凸筋10、周向凸起12和周向凸筋段13的高度可以为0.5mm-3.5mm，优选为1mm，径向延伸凸筋10、周向凸起12和周向凸筋段13的厚度为0.5mm-2mm，优选为1mm。
另外，通气降噪壳体连接端2可以具有多种结构形式，只要能够将通气降噪壳体14连接即可，例如，参考图3，通气降噪壳体连接端2为连接筒，该连接筒的外表面或内表面上形成有连接螺纹。
此外，本公开提供一种通气降噪组件23，参考图3、图4和图8，通气降噪组件23包括通气降噪单元6和以上任意所述的通气降噪壳体14，其中，通气降噪单元6包括通气降噪芯体7和外罩15，外罩15形成有通气开口16，外罩15连接在通气降噪单元安装壁段4上，通气降噪芯体7设置在外罩15和通气降噪单元安装壁段4之间并被支撑凸起结构支撑，通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，排气口5通过通气降噪芯体7和通气缝隙8与通气开口16连通。
如上所述的，该通气降噪组件23在实际使用中，由于支撑凸起结构支撑通气降噪芯体7，以让通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，当呼出废气从排气口5排出时，由于通气缝隙8的存在，呼出废气会通过通气缝隙8和通气降噪芯体7排出到通气降噪单元6的外部，呼出废气的流动可以参见图4中的箭头示意的，由于通气降噪芯体7对呼出废气的减缓作用，从而降低呼出废气冲刷排气口5产生的噪音，提升 静音效果，同时，呼出废气中携带的杂质例如灰尘的一小部分会在通气降噪芯体7上聚集，而大部分的杂质将随着呼出废气顺畅通过通气缝隙8以排出到通气降噪单元6的外部或者在远离排气口5的位置处聚集，从而不会堵塞排气口5，进而降低使用者的使用风险，提升了卫生性，以提升治疗效果。
通气降噪芯体7可以为滤棉或者为丝团。另外，通气降噪芯体7可以根据排气口5的布置形状来选用相应的形状，例如，对于图1和图2所示的排气口5，通气降噪芯体7可以为图8中所示的环形体。
另外，外罩15可以具有多种结构形式，例如，外罩15可以为环形网体，环形网体可以卡接在通道段上。例如，参考图8，外罩15包括外环体和内环体，内环体设置在外环体内并保持环形间距，外环体通过设置在环形间距内的多个周向间隔布置的连接条与内环体连接，其中，多个连接条将环形间距分隔为通气开口16，同时连接条可以限制装配在内的滤棉，使装配在内的滤棉稳定。这样，如图8和图9所示，一种实施例中，呼吸管连接端可以从内环体中穿过，而外环体则与呼吸通道段连接，从而将环形滤棉定位覆盖在环形布置的多个排气口5上，以进一步减轻排气噪声。
此外，本公开提供一种通气保湿装置，参考图5、图8和图9，通气保湿装置17包括通气保湿装置壳体18和以上任意所述的通气降噪壳体14，其中，通气保湿装置壳体18和通气降噪壳体连接端2连接，并且通气保湿装置壳体18包括呼吸面罩连通端19，通气保湿装置17包括位于呼吸面罩连通端19和呼吸管连通端3之间的呼吸通道20，呼吸通道20包括呼吸通道段1；呼吸通道20包括位于呼吸面罩连通端19和呼吸管连通端3之间的通气保湿单元容纳段21，通气保湿单元容纳段21用于容纳设置允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过的通气保湿单元22；通气降噪单元安装壁段4位于通气保湿单元容纳段21和呼吸管连通端3之间。
在该技术方案中，由于通气保湿单元容纳段21用于容纳设置允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过的通气保湿单元22，并且通气降噪单元安装壁段4位于通气保湿单元容纳段21和呼吸管连通端3之间，这样，在实际使用中，允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过的通气保湿单元22可以设置在通气保湿单元容纳段21内，由于通气 保湿单元22能够用于允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过，呼吸面罩连通端将和呼吸面罩连通，这样，佩戴者的呼出气体(排气)可以通过通气保湿单元从排气口排出，此时，呼出气体中的水分和热量在通气保湿单元的减缓作用下，呼吸面罩连通端和通气保湿单元之间的通道段内的湿度将会增大，并且水分可以在通气保湿单元中凝结以使得通气保湿单元的内部湿度也增大，同时，呼出气体中含有的热量会使得呼吸面罩连通端和通气保湿单元之间的通道段以及通气保湿单元的温度升高，这样，提供给佩戴者的可呼吸气体在经过通气保湿单元，以及呼吸面罩连通端和通气保湿单元之间的通道段时，在增大的湿度和升高的温度的作用下，该通气保湿装置就可以向佩戴者提供保湿保热的可呼吸气体，提升佩戴呼吸面罩的舒适感，另外，该通气保湿装置能够与呼吸面罩和呼吸管连通，由于呼吸面罩和呼吸管的轻型便捷性，因此，该通气保湿装置体积小并且能够灵活便捷地携带，从而能够灵活便捷地向呼吸面罩的佩戴者提供保湿保热的呼吸气体。当然，如果需要，通气保湿单元容纳段可以用于容纳设置至少两种不同规格的通气保湿单元，从而可以灵活便捷地更换所需的通气保湿单元。同时，如上所述的，由于支撑凸起结构支撑通气降噪芯体，以让通气降噪芯体和通气降噪单元安装壁段的外表面之间至少部分保持通气缝隙，当呼出废气从排气孔排出时，由于通气缝隙的存在，呼出废气会通过通气缝隙和通气降噪芯体从通气开口处排出到外部，由于通气降噪芯体对呼出废气的减缓作用，从而降低呼出废气冲刷排气口产生的噪音，提升静音效果，同时，呼出废气中携带的杂质例如灰尘的一小部分会在通气降噪芯体上聚集，而大部分的杂质将随着呼出废气顺畅通过通气缝隙以从通气开口处排出到外部或者在远离排气口的位置处聚集，从而不会堵塞排气口，进而降低使用者的使用风险，提升了卫生性，以提升治疗效果。
另外，参考图8和图9，通气保湿装置包括通气降噪单元6，其中，通气降噪单元6包括通气降噪芯体7和外罩15，外罩15形成有通气开口16，外罩15连接在通气降噪单元安装壁段4上，通气降噪芯体7设置在外罩15和通气降噪单元安装壁段4之间并被支撑凸起结构支撑，通气降噪芯体7和通气降噪单元安装壁段4的外表面之间至少部分保持通气缝隙8，排气口5通过 通气降噪芯体7和通气缝隙8与通气开口16连通；这样，如上所述的，该通气保湿装置可以便捷地向呼吸面罩的佩戴者提供保湿保热的呼吸气体，同时能够降低排气噪音，提升卫生性。
另外，该通气保湿装置可以不包括通气保湿单元22，而在实际使用时，可以将通气保湿单元22装配在通气保湿单元容纳段21内。或者，参考图5所示的一种实施例，以及图8和图9所示的另一种实施例，通气保湿装置包括通气保湿单元22，通气保湿单元22设置在通气保湿单元容纳段21中，也就是，作为一种独立产品的通气保湿装置，通气保湿单元容纳段21装配有通气保湿单元22。
另外，通气保湿单元22可以具有多种形式，例如，图5显示了一种通气保湿单元22，图8显示了两种不同规格的通气保湿单元22。例如，参考图6和图7所示的通气保湿单元22，该通气保湿单元22包括内部气道25和环形的外部气缝26，内部气道25内设置有通气保湿芯体27，通气保湿芯体27允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过。这样，参考图7，呼出废气可以直接冲击该通气保湿芯体27的端平面，如图7中的箭头所示，呼出废气会分散到外部气缝26处，在呼吸过程中，因为呼吸气流和呼出废气会产生对冲，这会进一步减弱呼出废气通过外部气缝26，进而减小呼出气流冲击外部气缝26的噪音。而相对于供给的呼吸气流而言，人体呼出的气体的流速较弱，在相对强的供给的呼吸气流的作用下，呼出废气会更多的经过内部气道25，而这也进一步增加保湿保热性能。
另外，参考图10，通气保湿单元22的其他可选择的实施例中，通气保湿单元22包括内部气道25和设置在内部气道25外部的环形的外部气缝26，内部气道25内设置有通气保湿芯体27，通气保湿芯体27用于允许呼吸气体通过并能够减缓呼出气体中的水分和热量通过，其中，在通气保湿单元22的至少朝向呼吸管连通端3的一端部，外部气缝26的环形外侧壁30轴向延伸越过外部气缝26的环形内侧壁31，并且环形内侧壁31的一端包括用于将轴向流动的一部分呼吸气体偏转引导流向外部气缝26的迎气偏转面32。这样，参考图10，由于外部气缝26的环形外侧壁30轴向延伸越过外部气缝26的环形内侧壁31，这样，在内部气道25内，就可以降低通气保湿芯体27的轴向长 度，因外部气缝26的阻力较小，内部气道25的气阻较大，这样，外部气缝26的流速快，内部气道25的流速慢，从而造成内外压强差，导致呼吸气体会较多的经过外部气缝26，这样呼吸气体的阻力会降低很多，从而便于患者更轻松地吸取呼吸气体。同时，参考图10的弯曲箭头所示，由于迎气偏转面32能够将轴向流动的一部分呼吸气体偏转引导流向外部气缝26，部分偏转到达环形外侧壁31的内表面再次偏转与进气气流产生对冲，这会减弱气流的能量，进而减小呼吸气流冲击通气保湿单元22的壳体的噪音。相对于从进气端进入的呼吸气流，人体呼出的呼出气体的流速较弱，在相对强的气流下，呼出气体会更多的经过内部气道25内的通气保湿芯体27，而这也会增加保湿性能。
另外，可以通过多种方式在环形内侧壁31的一端形成迎气偏转面32，例如，可以将图7所示的环形内侧壁31的端部的一部分切除，从而使得图7所示的环形内侧壁31的端面作为迎气偏转面32。或者，可以在环形内侧壁31的一端设置环形的迎气偏转板，该迎气偏转板的板面可以作为迎气偏转面32。
此外，呼吸管连通端3可以直接连接呼吸管，或者可以用于套装连接套28，连接套28则可以连接呼吸管。
此外，本公开提供一种呼吸面罩组件，参考图8和图9，该呼吸面罩组件包括呼吸面罩和以上所述的通气降噪组件23，其中，呼吸面罩包括具有呼吸腔的面罩本体24，呼吸通道段1和呼吸腔连通，例如，呼吸通道段1可以直接和面罩本体24连接，或者可以通过呼吸面罩组件的其他管件例如软管等和面罩本体24连接。这样，如上所述的，该呼吸面罩组件的品质得到有效提升。
此外，本公开提供一种呼吸面罩组件，参考图8和图9，该呼吸面罩组件包括呼吸面罩和以上任意所述的通气保湿装置17，其中，呼吸面罩包括具有呼吸腔的面罩本体24，呼吸面罩连通端19和呼吸腔连通，例如，呼吸面罩连通端1可以直接和面罩本体24连接，或者可以通过呼吸面罩组件的其他管件例如软管等和面罩本体24连接。这样，如上所述的，该呼吸面罩组件的品质得到有效提升。
最后，本公开提供一种呼吸支持设备，该呼吸支持设备包括呼吸机(未图示)、呼吸管(未图示)和以上所述的呼吸面罩组件，其中，呼吸机通过呼吸管和呼吸管连通端3连通。这样，如上所述的，该呼吸支持设备的品质得到有效提升。
以上结合附图详细描述了本公开的优选实施方式，但是，本公开并不限于此。在本公开的技术构思范围内，可以对本公开的技术方案进行多种简单变型。包括各个具体技术特征以任何合适的方式进行组合。为了避免不必要的重复，本公开对各种可能的组合方式不再另行说明。但这些简单变型和组合同样应当视为本公开所公开的内容，均属于本公开的保护范围。
