Description

一种用于呼吸阀内单向膜片安装的支撑架 技术领域
本发明涉及呼吸阀技术领域，具体涉及一种用于呼吸阀内单向膜片安装的支撑架。
背景技术
如图1所示，在现有的呼吸阀中，进气通道末端通常装有单向膜片2，以防止患者呼出的气体回流污染机器，由于呼吸阀尺寸较小，为了方便单向膜片2安装，通常单独设置一个支架1，先在外部将单向膜片2安装于支架1上，具体地是将单向膜片2上设置的锥面小端201伸入支架1中心的安装孔101，然后用力挤压至单向膜片2上设置的锥面大端202也穿过安装孔101，再将支架1沿进气通道3推入至呼吸阀内预定的位置。
此时为了防止支架1从进气通道3内掉出，如图2所示，一般会采用在支架1上装密封圈4，利用该密封圈4的压缩量固定支架1，或者采用如图3所示的设置方式，即在进气通道3的内壁上设计凸起5，利用塑料的形变将支架1推入呼吸阀内后进行卡紧。但是，由于支架1推入进气通道3后再取出会比较困难，需要特殊的工具才能处理，因此上述两种单向膜片的安装方式仅解决了膜片初次安装的问题，而进行膜片更换操作依然很困难，进而降低了工作效率。
发明内容
本发明的目的在于，为解决呼吸阀中的单向膜片安装于现有的支架上，导致膜片更换不便的技术问题，提供一种便捷的用于呼吸阀内单向膜片安装的支撑架，所述的支撑架和阀体设计为一体结构，利用该支撑架既方便单向膜片的安装，又能够减少一个独立的支架零件，使呼吸阀的内部结构更加紧凑，消除了支架掉出的风险。
为实现上述目的，本发明提供的一种用于呼吸阀内单向膜片安装的支撑架，所述的支撑架设置于呼吸阀中进气通道的径向截面上，并与该进气通道为一体结构；该支撑架的中心设有供单向膜片安装的安装孔，所述安装孔的边缘沿周向分布有若干个气孔。
作为上述技术方案的进一步改进，所述的安装孔在靠近呼吸阀阀口的一侧设有供单向膜片中圆柱支撑结构穿入的缺口。
本发明的一种用于呼吸阀内单向膜片安装的支撑架优点在于：
本发明的支撑架通过与呼吸阀阀体设计为一体结构，从而简化了现有的支架所需的固定部件，使得呼吸阀的内部结构更加紧凑，避免支架掉出的风险；通过将支撑架的安装孔开设缺口，使得单向膜片的更换更为便利，极大地提高了工作效率。

具体实施方式
下面结合附图和实施例对本发明所述的一种用于呼吸阀内单向膜片安装的支撑架进行详细说明。
本发明的一种用于呼吸阀内单向膜片安装的支撑架，如图4所示，所述的支撑架8设置于呼吸阀中进气通道3的径向截面上，并与该进气通道3为一体结构，即本发明将安装单向膜片2的支撑架8与阀体6做为一体结构，如图5所示，该支撑架8的中心设有供单向膜片2安装的安装孔801，所述安装孔801的边缘沿周向分布有若干个气孔。
基于上述结构的支撑架，如图5所示，所述的安装孔801在靠近呼吸阀阀口7的一侧设有供单向膜片2中圆柱支撑结构204穿入的缺口803。另外，所述的支撑架8沿中心周向分布若干个气孔802。
如图5所示，利用支撑架8将单向膜片2安装于呼吸阀内的具体步骤为：
首先，打开呼吸阀，暴露阀口7，采取从呼吸阀阀口7处向下安装的方式。由于阀口7的尺寸较小，单向膜片2不易安装，故将支撑架8上的安装孔801设计为非整圆的孔，将缺口803设置在安装孔801的顶端，此时正上方的一个气孔802正对安装孔801的缺口803。
然后，将单向膜片2的圆面203与锥面大端202之间的圆柱支撑结构204对准缺口803后，向下挤压将该圆柱支撑结构204按入安装孔801即可。安装孔801的直径应略大于圆柱支撑结构204的直径，缺口803的尺寸可根据圆柱支撑结构204的直径尺寸确 定，以保证圆柱支撑结构204按入缺口803时有一定压缩量即可。
当需要更换单向膜片2时，仅需在进气通道端向上拨单向膜片2的圆锥端，圆柱支撑结构204即可从缺口803处滑出，方便拆卸。
最后所应说明的是，以上实施例仅用以说明本发明的技术方案而非限制。尽管参照实施例对本发明进行了详细说明，本领域的普通技术人员应当理解，对本发明的技术方案进行修改或者等同替换，都不脱离本发明技术方案的精神和范围，其均应涵盖在本发明的权利要求范围当中。
