具体实施方式
下面结合附图和具体实施例对本发明作进一步说明。
参阅图1，本发明提供了一种指环式血氧装置，当用户的手指伸入指环后，通过弹性件的弹性变形，以适配用户的手指，使得弹性件和指环能够包裹住手指，又能够避免指环箍得太紧，避免手指血液不同的情况，即利用凸起部和凹陷部张开或收拢以改变指环的整体内径，解决了血氧测量装置的指套难以适用于不同指围的使用者的问题，通过在指环中设置波浪形的弹性结构，以适用于不同指围的使用者，且该弹性结构也能降低环境光对血氧信号的影响，保证测量的准确性。下面结合附图对本发明指环式血氧装置进行说明。
参阅图1，图1为本发明指环式血氧装置的一种实施方式立体图。下面结合图1，对本发明指环式血氧装置进行说明。
如图1所示，本发明指环式血氧装置，包括：
指环11，指环11形成有开口；
连接于指环11的开口处且可弹性变形的弹性件12，弹性件12有部分沿指环11的径向向外凸起且有部分沿指环11的径向向内凹陷以形成若干交替设置的凸起部和凹陷部，使得弹性件12呈波浪形；
安装于指环11的内壁的发射器13；以及
对应发射器13且安装于指环11的内壁的接收器14。
较佳地，凸起部或凹陷部的周长与指环11的内周长的比为10％～20％。
具体的，还包括对应发射器13和接收器14开设于指环11的凹槽111以及固定于指环11的内壁且沿凹槽111的边缘设置的第一挡光圈112，发射器13和接收器14分别安装于对应的凹槽111内，当用户使用时第一挡光圈112能够贴合于用户的手指，从而能够将环境光阻挡在外。
具体的，还包括固定于指环11的内壁且沿指环11的边缘设置的第二挡光圈113，当用户使用时第二挡光圈113能够贴合于用户的手指，从而能够将环境光阻挡在外。
作为本发明的一较佳实施方式，结合图2所示，发射器13与指环11 的中心的连线和接收器14与指环11的中心的连线之间具有设定夹角。
较佳地，该设定夹角可以为30°～40°，从而保证无论指围较大或较小的用户使用时，接收器13都能够接收到发射器14发出的光，避免接收器14与发射器13发生较大范围的错位。
进一步的，还包括设置于弹性件12靠近侧部的位置且固定于凸起部内的封闭片121，封闭片121可弹性变形，该封闭片121为类似扇子的结构具有若干褶皱，当撑开弹性件12时，若干褶皱打开使得封闭片121展开，当弹性件12收拢时，若干褶皱收拢使得封闭片121收缩，即利用封闭片121阻挡外部光源，避免外部光源自弹性件12的凸起部射入指环11内。
作为本发明的另一较佳实施方式，结合图4所示，还包括设置于指环11靠近开口处的卡合部以及对应卡合部且设置于弹性件12的端部的扣合部，通过扣合部与卡合部卡扣连接，使得弹性件12与指环11固定连接，即用户可以在佩戴指环11后，再将弹性件12与指环11连接。
具体的，卡合部包括开设于指环11靠近开口处的卡槽114、固定于卡槽114的内壁的金属柱1141以及固定于卡槽114的底部且对应金属柱1141设置的磁铁1142；
扣合部包括固定于弹性件12的端部且由磁性材料制成的卡勾122，通过卡勾122勾住金属柱1141并与磁铁1142吸附连接，使得扣合部与卡合部卡扣连接。
作为本发明的又一较佳实施方式，结合图3所示，指环11沿中心线对称形成有两个开口；
弹性件12对应开口设置有两个。
进一步的，接收器14和发射器13相对设置且位于指环11的中心线上，由于指环11的两侧均可弹性调节，因此能够保证接收器14和发射器13始终在指环11的中心线上。
本发明的具体实施方式如下：
以指环11只有一个开口为例，使用者的手指穿过指环11，此时若使用者手指的指围较大，则弹性件12的凸起部和凹陷部展开，并包覆住手指，此时封闭片121也对应展开以防止外界光通过凸起部进入指环11内，发射器13发出光线，且接收器14接收到光线，从而对使用者进行血氧检测；
以指环11设置有卡合部且弹性件12设置有扣合部为例，使用者可以先将手指穿过指环11，进而将弹性件12绕过手指，并将卡勾122勾住金属柱1141并与磁铁1142吸附连接，使得扣合部与卡合部卡扣连接，从而弹性件12固定于指环11；
以指环11设置有两个开口为例，使用者的手指穿过指环11，此时若使用者手指的指围较大，则两个弹性件12的凸起部和凹陷部展开，并包覆住手指，由于弹性件12是对称设置的，因此发射器13与接收器14始终在指环11的中心线上。
以上结合附图实施例对本发明进行了详细说明，本领域中普通技术人员可根据上述说明对本发明做出种种变化例。因而，实施例中的某些细节不应构成对本发明的限定，本发明将以所附权利要求书界定的范围作为本发明的保护范围。
