指夹式血氧测量仪
技术领域
本发明属于医疗设备领域, 具体涉及一种指夹式血氧测量仪。 背景技术
在生命信息检测领域, 血氧饱和度是一个重要参数, 在临床医学上 常借助血氧饱和度来判断呼吸循环系统的健康状况。 血氧测量仪是用于 测量血氧饱和度的仪器。
传统的血氧测量仪包括上壳、 下壳以及弹簧, 上壳和下壳借助弹簧 以枢轴方式连接在一起, 并且上壳和下壳围成一个手指容腔, 该手指容 腔在一端具有供手指插入该手指容腔的开口。 在上壳的与手指插入方向 相平行的两侧和 /或在下壳的与手指插入方向相平行的两侧设有遮光板 , 以便至少是在被测者的手指插入该手指容腔时借助该遮光板来遮挡外 部的环境光进入手指容腔内。 尽管这种结构的血氧测量仪目前被广泛釆 用, 但是其在使用过程中存在以下缺点:
第一, 连接上壳和下壳的弹簧容易出现卡簧现象而导致血氧测量仪 无法正常使用; 第二, 尽管设有遮光板, 但是自然光还是容易从设置弹 簧的位置进入手指容腔内, 这将影响血氧饱和度的测量结果; 第三, 借 助设置在上 /下壳体端部的弹簧来施加夹持力通常会导致夹持力不均匀; 第四, 以枢轴连接方式连接的上壳和下壳的外形设计不易改变, 因而导 致血氧测量仪的外形设计单一。
为此, 中国专利申请 200920246562.9 公开了一种指套式血氧测量 仪, 该指套式血氧测量仪釆用了由软胶材料一体成型的大腔体, 在大腔 体内设有手指挡板, 从而将大腔体分隔为两个腔室: 其中, 一个腔室是 用于收容被测者手指的指套, 另一个腔室是用于容纳测量元件和数据处 理元件的机壳。 指套的一个侧面向外凸出而形成凸部, 以使得手指在插 入指套时可以获得更大的张开角度。 尽管该指套式血氧测量仪因未釆用 枢轴方式的连接结构而避免了现有枢轴连接结构所带来的问题, 然而在 实际应用中,该指套式血氧测量仪仍然不可避免地存在下述缺陷:其一, 其外形呈上窄、 下宽的形状(即, 显示屏所在的上侧较窄, 指套所在的 下侧较宽), 这将导致该血氧测量仪的整体体积较大, 不便于携带; 其 二, 指套呈锥形设计, 这导致手指夹持力不均勾; 其三, 测量元件、 数 据处理元件以及连接线路均设置在该指套式血氧测量仪的机壳内, 这不 利于该指套式血氧测量仪的装配操作, 从而使得在生产过程中容易出现 不合格产品, 并且在拆开清洗后再装配时容易导致电子元件的损坏。 发明内容

图 1 为本发明一个具体实施例提供的指夹式血氧测量仪的结构简 图;
图 2为图 1所示实施例提供的指夹式血氧测量仪的分体结构图; 图 3为图 1所示实施例提供的指夹式血氧测量仪沿其宽度方向的截 面图; 以及

为使本技术领域的人员更好地理解本发明的技术方案, 下面结合附 图对本发明提供的指夹式血氧测量仪进行详细说明。
图 1为本发明提供的指夹式血氧测量仪的结构简图; 图 2为本发明 提供的指夹式血氧测量仪的分体结构图; 图 3为本发明提供的指夹式血 氧测量仪沿其宽度方向的截面图; 图 4为本发明提供的指夹式血氧测量 仪沿其长度方向的截面图。 请一并参阅图 1至图 4 , 指夹式血氧测量仪 包括上壳体 1、 指套 2、 下壳体 3、 发光单元 6、 中心模块 4以及电池 9。 其中, 中心模块 4设置在上壳体 1 内, 发光单元 6和电池 9设置在下壳 体 3内。 指套 2用于容纳手指, 其设置在上壳体 1和下壳体 3之间, 并 分别与上壳体 1和下壳体 3连接。 当手指插入指套 2时, 指套 2在上壳 体 1和下壳体 3的叠置方向上具有收缩力, 即, 指套 2对上壳体 1和下 壳体 3施加相向的作用力, 以使上壳体 1和下壳体 3夹紧手指, 从而将 指夹式血氧测量仪固定在手指上。
本实施例中, 上壳体 1包括上壳 11、 上中壳 12以及上盖板 13 , 上 壳 11和上中壳 12相对设置, 且以卡接方式连接在一起。 在上壳 11和 上中壳 12之间形成一上壳体空间, 中心模块 4设置在该上壳体空间内。 上盖板 13设置在上壳 11的上表面, 用于保护中心模块 4不被损伤。 中 心模块 4 包括接收单元 7、 处理单元 (图中未示出)、 显示单元 41、 电 源管理单元 42以及数据通信接口 (图中未示出), 其中, 接收单元 7用 于接收发光单元 6发出的光信号, 并将光信号传送至处理单元; 处理单 元根据来自接收单元 7的光信号而获得血氧饱和度; 显示单元 41 用于 显示处理单元获得的血氧饱和度; 数据通信接口用于实现接收单元 7和 处理单元的数据传输以及处理单元和显示单元 41 之间的数据传输。 在 上中壳 12与接收单元 7相对的位置处设有上中壳透光孔 121 ,来自发光 单元 6的测量光线穿过上中壳透光孔 121而被接收单元 7接收。
下壳体 3包括下壳 31和下中壳 32 ,下壳 31和下中壳 32相对设置, 且通过卡接方式连接在一起。下壳 31包括下壳本体 311和下壳后盖 312 , 电池 9设置在下壳本体 311和下壳后盖 312形成的空腔内。 发光单元 6 设置在下壳 31和下中壳 32之间,用于发出测量血氧饱和度的测量光线。 在下中壳 32上与发光单元 6相对的位置处设有下中壳透光孔 323 ,发光 单元 6发出的测量光线自下中壳透光孔 323朝向接收单元 7射出。
请参阅图 2 , 指套 2釆用诸如硅橡胶等软硅胶材料制成, 其包括上 盖 22、 下盖 23、 第一褶边 24、 第二褶边 25 以及后盖 (图中未示出)。 其中, 上盖 22和下盖 23相对设置, 第一褶边 24、 第二褶边 25对称地 设置在上盖 22和下盖 23的两侧并分别连接上盖 22和下盖 23 , 即, 第一 褶边 24设置在上盖 22和下盖 23的左侧并与上盖 22和下盖 23连接, 与之对应地, 第二褶边 25设置在上盖 22和下盖 23的右侧并与上盖 22 和下盖 23连接。 不进行测量时, 指套 2的第一褶边 24和第二褶边 25 各自均类似于折叠起来的折扇那样地折叠在上盖 22和下盖 23之间, 以 使指套 2的上盖 22和下盖 23趋于闭合; 并且第一褶边 24和第二褶边 25的折叠层数相同,以便在进行血氧测量时该指套 2可向被测手指施加 均匀的夹持力。 指套 2的上盖 22、 下盖 23、 第一褶边 24以及第二褶边 25围成一个两端开口的容腔(也可称为套筒), 后盖 26设置在该容腔的 一个端部并将该端部封闭, 即, 由后盖 26将该容腔的一端的开口封闭。 这样, 指套 2的上盖 22、 下盖 23、 第一褶边 24、 第二褶边 25以及后盖 26围成一个仅有一个开口 21的腔室, 即, 指套 2为设有一个开口 21的 腔室。 在进行血氧测量时, 被测手指从该开口 21伸入指套 2内, 这样, 借助于上述仅具有一个开口 21的腔室结构状的指套 2 ,可以减少自然光 进入上述腔室, 从而提高血氧测量的精度。 本实施例中的指套 2可以一 体成型而成, 也可以是由上述上盖 22、 下盖 23、 第一褶边 24、 第二褶 边 25以及后盖 26拼接而成。
本实施例中, 指套 2的两侧釆用收缩力相同的第一褶边 24和第二 褶边 25 , 当手指插入指套 2时, 第一褶边 24和第二褶边 25因被向外拉 伸而产生收缩力, 从而使上壳体 1和下壳体 3紧靠手指并将指夹式血氧 测量仪固定在手指上。 由于第一褶边 24和第二褶边 25的收缩力的方向 均是在上壳体 1和下壳体 3的叠置方向上, 而且收缩力均匀, 因此, 指 套 2作用在被测手指上的由上述收缩力而产生的夹持力也就均匀, 这样 便提高了该指夹式血氧测量仪的舒适度。
可以理解, 在实际应用中, 指套的结构并不局限于前述结构, 而是 也可以釆用其它结构, 只要其能够在上壳体和下壳体的叠置方向上对被 测手指施加大小相等的夹持力即可。 换言之, 只要能够在上壳体和下壳 体的叠置方向上对被测手指施加大小相等的夹持力的指套结构就都可 以用于本发明, 并且其都能提高指夹式血氧测量仪的舒适度。
如图 4所示, 在指套 2的下盖 23上的靠近后盖 26的位置处设有向 上突出的定位凸起 27 , 用于在测量血氧时限定手指伸入指套 2的深度, 以使手指处于适于测量的位置。 具体地, 在测量血氧时, 当伸入指套 2 的手指端部触及该定位凸起 27时, 表明当前手指处于适于测量的位置, 这样可以获得准确的测量结果。 当然, 定位凸起 27 并不局限于上述设 置方式, 在实际应用中也可以是在指套 2的上盖 22上的靠近后盖 26的 位置处设置向下突出的定位凸起。 本实施例中, 在定位凸起 27 与后盖 26之间设有布线空间 28 , 即, 定位凸起 27与后盖 26在指夹式血氧测 量仪的长度方向相距一定距离, 以使定位凸起 27与后盖 26之间形成一 空间, 用于使用来连接设置在上壳体 1和下壳体 3内的电气部件的导线 穿过该布线空间 28 , 也就是说, 布线空间 28用于指夹式血氧测量仪的 走线以及收容导线的冗余部分。 本实施例中的指夹式血氧测量仪由于设 有独立的布线空间 28 , 因此, 其导线不会暴露在指夹式血氧测量仪的外 部, 而且, 即使导线的冗余长度较长, 也可以完全将其放置在布线空间 28内, 这样, 即便是在手指插入指套 2而使上壳体 1和下壳体 3在指夹 式血氧测量仪的垂直方向张开时, 也不会使导线外露。 因此, 布线空间 28可以避免因导线外露而影响指夹式血氧测量仪的美观性; 而且, 布线 空间 28还可以增加导线的冗余量,从而可以避免因上壳体 1和下壳体 3 的相对运动而导致导线损坏, 进而提高指夹式血氧测量仪的使用寿命。
本实施例中, 在上盖 22和下盖 23上分别设有上盖透光孔 221和下 盖透光孔 231 , 上盖透光孔 221和下盖透光孔 231设置在与发光单元 6 的相对位置处, 以使测量光线可由此穿过上盖 22和下盖 23而被接收单 元 7接收。 在上盖透光孔 221和下盖透光孔 231的位置处还设有透光的 保护膜, 以避免发光单元 6和接收单元 7在手指插入或退出指套 2的过 程中被损坏。
本实施例中, 指套 2通过连接部件 5 ( 5, )分别与上壳体 1和下壳 体 3连接, 即, 指套 2通过第一连接部件 5连接上壳体 1 , 并且通过第 二连接部件 5, 连接下壳体 3。 第一连接部件 5 包括连第一接部件本体 511以及固定在第一连接部件本体 511上的卡钩 52; 第二连接部件 5, 包括连第二接部件本体 512以及固定在第二连接部件本体 512上的卡钩 52。 第一连接部件本体 511和第二连接部件本体 512在水平面上的投影 的轮廓线尺寸比指套 2在水平面上投影的轮廓线尺寸稍小, 但二者的投 影轮廓线的形状相同, 并且在第一连接部件本体 511的上表面和第二连 接本体 512的下表面均勾地间隔设置有多个卡钩 52。对应于设置在第一 连接部件本体 511的上表面的多个卡钩 52 , 而在上中壳 12和上盖 22上 开设多个与所述卡钩 52相配合的卡孔 8; 在进行装配时, 使第一连接部 件本体 511的上表面的多个卡钩 52 自指套 2的容腔内向上依次穿过上盖 22上的卡孔 8和上中壳 12上的卡孔 8 , 并最终卡扣在上中壳 12的上表 面, 从而将指套 2与上壳体 1连接在一起。 类似地, 对应于设置在第二 连接部件本体 512的下表面的多个卡钩 52 ,而在下盖 23和下中壳 32上 开设多个与所述卡钩 52相配合的卡孔 8; 在进行装配时, 使第二连接部 件本体 512的下表面的多个卡钩 52 自指套 2的容腔内向下依次穿过下盖 23上和下中壳 32上的卡孔 8的卡孔 8 , 并最终卡扣在下中壳 32的下表 面, 从而将指套 2与下壳体 3连接在一起。
需要指出的是, 本实施例中的指套 2与上壳体 1和下壳体 3也可以 通过热压方式连接在一起。 并且, 发光单元 6可以是发光管, 接收单元 7可以是光敏管。
还需要指出的是, 尽管前述实施例中的连接部件本体为一体结构, 然而本发明并不局限于此, 在实际应用中, 也可以将连接部件本体设置 成四段, 即, 对应于指夹式血氧测量仪的四个边而将第一连接部件本体 和第二连接部件本体分为四段, 且视每一段第一连接部件本体的长度而 在每一段的上表面分别设置一个或多个卡钩, 用于实现指套与上壳体的 连接, 并在装配时分别使四段连接部件本体上的各个卡钩依次穿过设置 在上盖和上中壳的相应的卡孔, 并卡扣在上中壳的上表面; 并且视每一 段第二连接部件本体的长度而在每一段的下表面分别设置一个或多个 卡钩, 用于实现指套与下壳体的连接, 并在装配时分别使四段连接部件 本体上的各个卡钩依次穿过设置在下盖和下中壳的相应的卡孔, 并卡扣 在下中壳的下表面。 不难理解, 相对于分段设置的连接部件本体而言, 釆用一体结构的连接部件本体能够使指套与上壳体和下壳体的连接过 程更简单、 连接更牢固。
类似地, 尽管前述实施例中的连接部件为一体结构, 然而本发明并 不局限于此, 在实际应用中, 也可以将第一连接部件和第二连接部件设 置为若干独立的连接单元, 并且每一个连接单元均包含有一截连接部件 本体以及设置在该连接部件本体的上表面或下表面上的一个卡钩。 具体 地, 位于指套和上壳体之间的第一连接部件包括多个第一连接单元, 每一 个第一连接单元均包括一截连接部件本体以及设置在所述一截连接部件本体 的上表面的一个卡钩, 并且在上中壳和指套的上盖上设置多个与第一连接单 元的卡钩相配合的卡孔; 类似地, 位于指套和下壳体之间的第二连接部件 包括多个第二连接单元, 每一个第二连接单元均包括一截连接部件本体以及 设置在所述一截连接部件本体的下表面的一个卡钩, 在下中壳和指套的下盖 上设置多个与第二连接单元的卡钩相配合的卡孔。进行装配时,使每一个第 一连接单元的卡钩均自指套的容腔内向上依次穿过指套的上盖上的一个相应 卡孔和上中壳上的一个相应卡孔并卡接在上中壳的上表面; 并且使每一个第 二连接单元的卡钩均自指套的容腔内向下依次穿过指套的下盖上的一个相应 卡孔和下中壳的一个相应卡孔并卡接在下中壳的下表面。 也就是说, 当釆 用上述连接单元进行装配时, 上盖和上中壳或下盖和下中壳上的每一个 卡孔均对应一个连接单元。 不难理解, 在实际应用中, 前述所谓一段连 接部件可包括一个或多个在此所描述的一截连接部件本体, 即, 上中壳 上的一个卡孔或者其上相邻的多个卡孔对应一个连接单元, 与之对应 地, 上盖上的一个卡孔或者其上相邻的多个卡孔对应一个连接单元; 类 似地, 下中壳上的一个卡孔或者其上相邻的多个卡孔对应一个连接单 元, 与之对应地, 下盖上的一个卡孔或者其上相邻的多个卡孔对应一个 连接单元。 此外, 相对于设置成独立的连接单元结构的连接部件而言, 釆用一体结构的连接部件能够使指套与上壳体和下壳体的连接过程更 简单、 连接更牢固。
进一步地, 虽然前述实施例中仅在第一连接部件本体的上表面或第 二连接部件本体的下表面设置卡钩, 然而本发明并不局限于此, 在实际 应用中, 也可在第一连接本体和第二连接部件本体的上表面和下表面同 时设置卡钩。 例如, 对应于设置在第一连接部件本体的上表面的多个卡 钩, 而在上中壳上开设多个与所述卡钩相配合的卡孔; 对应于设置在第 一连接部件本体的下表面的多个卡钩, 而在上盖上开设多个与所述卡钩 相配合的卡孔。 进行装配时, 使第一连接部件本体上表面的多个卡钩向 上穿过上中壳上的卡孔并卡扣在上中壳的上表面; 使第一连接部件本体 的下表面的多个卡钩向下穿过上盖上的卡孔并卡扣在上盖的下表面, 从 而将指套与上壳体连接在一起。 并且, 对应于设置在第二连接部件本体 的上表面的多个卡钩, 而在下盖上开设多个与所述卡钩相配合的卡孔; 对应于设置在第二连接部件本体的下表面的多个卡钩, 而在下中壳上开 设多个与所述卡钩相配合的卡孔。 进行装配时, 使第二连接部件本体上 表面的多个卡钩向上穿过下盖上的卡孔并卡扣在下盖的上表面; 使第二 连接部件本体的下表面的多个卡钩向下穿过下中壳的卡孔并卡扣在下 中壳的下表面, 从而将指套与下壳体连接在一起。 可以理解的是, 在实 际应用中, 连接部件本体的上表面和下表面上所设置的卡钩可上下对应 设置, 也可上下错位设置, 只要在所述上中壳和上盖或所述下中壳和下 盖上的卡孔与相应的卡钩对应设置即可。
类似地, 在实际应用中, 也可以在第一连接本体和第二连接部件本 体的上表面和下表面同时设置卡钩并使各连接部件本体设置成四段, 即, 对应于指夹式血氧测量仪的四个边而将第一连接部件本体和第二连 接部件本体分为四段, 且视每一段第一连接部件本体的长度而在每一段 的上表面和下表面分别设置一个或多个卡钩, 用于实现指套与上壳体的 连接, 并在装配时分别使四段连接部件本体上表面的各个卡钩穿过设置 在上中壳上的卡孔, 并卡扣在上中壳的上表面; 使四段连接部件本体下 表面的各个卡钩穿过设置在上盖上的卡孔, 并卡扣在上盖的下表面。 并 且视每一段第二连接部件本体的长度而在每一段的上表面和下表面分 别设置一个或多个卡钩, 用于实现指套与下壳体的连接, 并在装配时分 别使四段连接部件本体上表面的各个卡钩穿过设置在下盖上的卡孔, 并 卡扣在下盖的上表面; 使四段连接部件本体下表面的各个卡钩穿过设置 在下中壳的卡孔, 并卡扣在下中壳的下表面。 不难理解, 相对于分段设 置的连接部件本体而言, 釆用一体结构的连接部件本体能够使指套与上 壳体和下壳体的连接过程更简单、 连接更牢固。
类似地,在实际应用中,也可以将连接部件设置为独立的连接单元, 并且每一个连接单元均包含有一截连接部件本体以及分别设置在该连 接部件本体的上表面和下表面的两个卡钩。 其中, 位于指套和上壳体之 间的第一连接部件所包含的各个连接单元称为第三连接单元, 与之相对 应, 在上中壳上设置多个与第三连接单元中的上卡钩相配合的卡孔, 在指套 的上盖上设置多个与第三连接单元中的下卡钩相配合的卡孔, 在此, 所谓第 三连接单元中的上卡钩指的是设置在第三连接单元中的连接部件本体 的上表面上的卡钩; 所谓第三连接单元中的下卡钩指的是设置在第三连 接单元中的连接部件本体的下表面上的卡钩。 类似地, 位于指套和下壳 体之间的第二连接部件所包含的各个连接单元称为第四连接单元, 与之 相对应, 在指套的下盖上设置多个与第四连接单元中的上卡钩相配合的卡 孔, 在下中壳上设置多个与第四连接单元中的下卡钩相配合的卡孔, 在此, 所谓第四连接单元中的上卡钩指的是设置在第四连接单元中的连接部 件本体的上表面上的卡钩; 所谓第四连接单元中的下卡钩指的是设置在 第四连接单元中的连接部件本体的下表面上的卡钩。 进行装配时, 第三 连接单元中的上卡钩向上穿过上中壳上的一个卡孔并卡扣在上中壳的上 表面, 第三连接单元中的下卡钩向下穿过上盖上的一个卡孔并卡扣在指 套的上盖的下表面。 同时使第四连接单元中的上卡钩向上穿过指套的下 盖上的一个卡孔并卡扣在指套的下盖的上表面, 第四连接单元中的下卡 钩向下穿过下中壳的一个卡孔并卡扣在下中壳的下表面。 不难理解, 在 实际应用中, 前述的每一段连接部件均可包括一个或多个在此所描述的 所谓一截连接部件本体, 即, 上中壳上的一个卡孔或者其上相邻的多个 卡孔对应一个连接单元, 与之对应地, 上盖上的一个卡孔或者其上相邻 的多个卡孔对应一个连接单元; 下中壳上的一个卡孔或者其上相邻的多 个卡孔对应一个连接单元, 与之对应地, 下盖上的一个卡孔或者其上相 邻的多个卡孔对应一个连接单元。 此外, 相对于设置成独立的连接单元 结构的连接部件而言, 釆用一体结构的连接部件能够使指套与上壳体和 下壳体的连接过程更简单、 连接更牢固。
可以理解的是, 本发明中所谓的 "上表面"、 "下表面"、 以及 "向 上" 和 "向下" 等方向性的描述均是按照附图所示的指夹式血氧仪的方 向进行定义和描述的, 然而, 在实际应用中, 本发明并不局限于此, 而 是可以根据实际方向进行相关定义和描述。
还可以理解的是, 本发明前述实施例提供的指夹式血氧测量仪将独 立的指套设置在上壳体和下壳体之间, 由于该指套本身具有收缩力, 因 而当被测手指插入该指套时, 该指套不仅可以使上壳体和下壳体夹紧被 测手指, 而且还可以使施加在被测手指上的夹持力更加均匀, 从而提高 指夹式血氧测量仪在测量时的准确度及舒适度。 另外, 指套设置在上壳 体和下壳体之间, 指套仅需在上壳体、 下壳体的叠置方向上发生变形即 可使被测手指插入其内, 并使上壳体、 下壳体紧靠已插入到指套内的手 指部分, 这种结构可以使该指夹式血氧测量仪的结构更紧凑, 从而减小 该指夹式血氧测量仪的体积。 而且, 测量元件、 数据处理元件可以分置 于上壳体、 下壳体内, 有利于指夹式血氧测量仪的组装, 从而使得制造 以及拆装清洗后的装配过程更加简单。 此外, 利用指套连接上壳体和下 壳体可以避免釆用枢轴连接方式所带来的问题。 而釆用的示例性实施方式, 然而本发明并不局限于此。 对于本领域内的 普通技术人员而言, 在不脱离本发明的精神和实质的情况下, 可以做出 各种变型和改进, 这些变型和改进也视为本发明的保护范围。
