本发明属于医疗设备技术领域， 具体涉及一种指套式血氧测量仪。 背景技术
随着社会经济的发展及生活水平的不断提高， 人们的日常保健意识也在 逐渐增强， 越来越多的家庭开始使用一些家用测试仪器来测量脉率和血氧饱 和度值， 尤其是一些患有呼吸系统疾病或者心脑血管疾病等的患者。 例如， 越来越多的家庭用户已经开始青睐于血氧测量仪。 现有的血氧测量仪一般分 为指夹式血氧测量仪和指套式血氧测量仪， 指套式血氧测量仪由于具有良好 的手指舒适性和较高的准确度， 越来越受到人们的青睐。
现有的指套式血氧测量仪包括软胶外套和机壳， 软件指套上设置有测量 元件， 机壳内设置有包括数据处理和显示的其他的电路元件， 并且与软胶外 套形成手指容腔。 测量者只需将手指放在该手指容腔中即可得知脉率和血氧 饱和度值， 因此该指套式血氧测量仪具有测量操作简单、体积小、携带方便、 可随时监测脉率和血氧饱和度值等的优点。
例如，申请号为 200920246562.9的中国专利申请就公开了这样一种指套 式血氧测量仪。 该指套式血氧测量仪包括软胶外套和机壳， 所述软胶外套和 机壳由相同材料一体成型为一个大腔体， 并在该大腔体中设置手指挡板将其 分隔为两个腔室， 一个用于容纳测量元件和数据处理元件， 另一个用于容纳 被测手指， 其中在该软胶外套的上部嵌入金属防护板， 用于固定和保护元器 件。 这种血氧测量仪由于只有一块金属防护板作为固定架， 因此不够硬实， 并且该血氧测量仪的零部件需要分别安装至一体成型的大腔体内， 装配较复 杂。 此外， 该指套式血氧测量仪电池仓较小， 只能容纳电量较小、 体积较小 的电池， 缩短了使用时间， 并且电池盖与血氧仪测量仪的结合力较大， 不便 于用户 （特别是老年人） 更换电池。 发明内容
本发明的目的在于针对上述存在的问题， 提供一种指套式血氧测量仪， 其安装容易并且比较结实， 同时体积较小且使用时间也相对较长。
为此， 本发明提供了一种指套式血氧测量仪， 其包括软胶外套和盒体， 所述盒体上部设置有显示屏， 用于显示测量结果， 所述软胶外套上设置有与 所述显示屏相应的开口， 所述软胶外套套于所述盒体外， 所述盒体用于容纳 和保护电路板， 所述盒体下部与所述软胶外套的底部围成手指容腔， 用于容 纳被测手指， 所述软胶外套的底部设置有第一测量模块， 在所述盒体内与所 述第一测量元件相对应的位置处设有第二测量模块。 其中， 所述电路板上集 成有数据处理模块、 电源管理模块、 数据釆集模块、 数据通信接口。
其中， 所述盒体包括并置的电路板腔和电池腔， 所述电池腔用于容纳干 电池， 所述电路板腔用于容纳电路板； 所述电池腔仅能容纳一节干电池， 该 电池为所述指套式血氧测量仪供电。
其中， 所述盒体的下部设置有手指挡板， 所述手指挡板与所述软胶外套 的底部围成所述手指容腔； 优选地， 所述手指挡板为弧形状， 且所述盒体的 前侧为与所述弧形状相适应的弧形边缘； 优选地， 所述手指挡板上设置有软 胶垫片。
其中， 所述手指挡板通过卡扣或螺钉方式与所述盒体结合， 或者所述手 指挡板与所述盒体一体成型。
其中， 所述盒体的末端上部设置有凸缘， 所述软胶外套上设置有与所述 凸缘相配合的迂回部， 所述迂回部与所述软胶外套形成凹槽， 供所述凸缘嵌 入， 以使所述盒体与软胶外套紧密配合。
其中， 所述盒体的后侧设置有电池盖， 所述电池盖通过枢轴与所述盒体 连接并与所述盒体通过滑动方式扣合。
其中， 所述盒体由金属材料或硬质有机材料制成， 其中当釆用金属材料 时需要设置相应的绝缘层， 以使盒体与盒体内的电路元件绝缘。
釆用本发明提供的指套式血氧测量仪具有如下有益效果：
本发明的指套式血氧测量仪， 由于单独设置了用于容纳电路元件的盒 体， 大部分电路元件设置在盒体内， 使电路元件可获得良好保护不易损坏， 同时这种设置也使得血氧测量仪装配容易并且比较结实。 当将电路元件装配 在盒体内后， 剩余的装配工作仅是使盒体内的电路元件与位于软胶外套底部 的测量元件电连接并将软胶外套套在盒体上， 所以使本发明血氧测量仪的装 配更加容易， 并且软胶外套可减轻由摔落或其他碰撞对盒体和盒体的电路元 件造成的损坏， 从而使得血氧测量仪更加结实。 此外， 由于软胶外套与盒体 釆用套合的方式， 使得较容易更换和清洗软胶外套， 以及维护或更换电路元 件。
此外， 在本方明一个优选实施例中， 将盒体分隔为两个并置的腔体： 电 池腔和电路板腔， 使其厚度相对于上下设置两个腔体的情形或其他类似情形 中的厚度较小； 而且所述电池腔设置为单电池腔， 减小了盒体的宽度， 从而 可釆用厚度和宽度都较小的盒体。 因此， 本发明的指套式血氧测量仪不仅充 分利用了盒体的空间， 而且减小了整体体积。 附图说明

为了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 对本发明提供的指套式血氧测量仪进行详细描述。
其中， 为了便于描述， 约定本发明所述的前侧或前端是指距离软胶外套 的手指容腔开口较近的一侧， 本发明所述的后侧或末端是指远离软胶外套的 手指容腔开口的一侧； 本发明所述的上部或上端是指显示屏所在的一侧， 本 发明所述的下部、 底部或下侧是指与所述显示屏相对的一侧。
请一并参阅图 la至图 4,本发明提供的指套式血氧测量仪包括软胶外套 5 , 盒体 4、 电池 6以及置于盒体 4或软胶外套 5内的数据处理模块、 电源管 理模块、 数据釆集模块、 数据通信接口。
其中， 软胶外套 5的后侧设置有开口， 通过该开口可将软胶外套 5套在 盒体 4上， 盒体 4的下部与软胶外套 5的底部围成手指容腔 8, 用于容纳被 测手指， 所述开口位于手指容腔 8的上方， 从而开口和手指容腔不会贯通。 软胶外套 5的底部安装有数据釆集模块中的第一测量模块， 在盒体 4上与所 述第一测量元件相对的位置处设置有数据釆集模块中的第二测量模块， 所述 第一和第二测量模块为发射电路板和接收电路板中的其中之一， 即， 其中的 一个为发射电路板， 用于发射测量光束； 另一个为接收电路板， 用于接收经 过被测手指后的测量光束， 并将测量数据传输至数据处理模块， 以经过相应 的数据处理而获得人体的血氧含量。 其中， 盒体 4釆用金属材料或硬质有机 材料制成（当釆用金属材料时需要设置相应的绝缘层， 以使盒体与盒体内的 电路板绝缘），具有较高的硬度和强度，可以有效保护置于盒体 4内的电路元 件， 软胶外套 5具有较高的物理柔软性和弹性， 可紧密贴合在盒体 4上， 并 且用于围成手指容腔 8的软胶外套底部 53可随手指外形变化与手指紧密贴 合， 同时具有较高的使用舒适性。
下面结合附图对盒体 4和软胶外套 5的具体结构进行详细描述。
如图 la和 lb所示， 盒体 4的上部设置有显示屏 1和按钮 2, 在软胶外 套 5的上部设置与显示屏 1形状相适配的开口 54和与按钮 2形状相适配的中 空的按钮保护部 55。为了便于盒体 4内的电路板与软胶外套 5底部的电路板 进行通信， 在盒体 4的侧面设置缺口 41 , 同时在软胶外套 5上与缺口 41相 应的位置处设置走线槽 51 , 从而使相应的连接线容易装配并且整齐不凌乱。
在实际应用中， 可使位于软胶外套 5底部的电路板与软胶外套 5—体成 型，并通过走线槽 51及设置于软胶外套 5上的走线孔引出相应的连接线，这 样当装配本发明提供的血氧测量仪时就可先安装盒体 4内的电路板， 然后使 前述引出的连接线通过缺口 41与盒体 4内的电路板电连接，最后将软胶外套 5套在盒体 4上， 从而大大简化了装配过程。
如图 2所示， 盒体 4的内部设置有一隔板， 将盒体 4的内部分隔为并置 的两个腔体： 电路板腔 43和电池腔 44。 电路板腔 43用于容纳数据处理电路 板， 该电路板上可集成数据处理模块、 电源管理模块、 数据釆集模块、 数据 通信接口； 电池腔 44用于容纳电池 6 , 电池 6为血氧测量仪的电路板供电。 在盒体 4下面设置手指挡板 7 , 该手指挡板 7与软胶外套的底部 53围成手指 容腔 8 , 用于容纳被测手指。 为了提高舒适度， 手指挡板 7做成弧形状， 并 且粘贴软胶垫片 72 , 同时盒体 4的前侧设置成弧形边缘， 以与手指挡板 7相 适配。 在手指挡板 7上与第二测量模块相对应的位置处设置有透明视窗 71 , 便于光束通过。 手指挡板 7与盒体 4可以通过卡扣的方式结合， 也可以通过 螺钉的方式结合， 在本实施例中釆用螺钉方式结合， 在盒体 4的前端设置有 螺紋孔 46 , 手指挡板 7上相应的设置有安装孔 74。 当然， 在实际应用中， 手 指挡板 7也可与盒体 4一体成型。
如图 3所示， 盒体 4的后侧为电池盖 3 , 电池盖 3上有电极片 31 , 其电 路连接为： 电池正极通过电极片 31传给电接口 32 , 然后传给数据电路板等。 电池盖 3包括连接部和滑动部， 连接部与盒体 4通过枢轴连接， 滑动部可在 连接部滑动并与盒体 4扣合， 因此电池盖 3在与盒体具有较高结合力的同时 又较易打开。 此外， 在和盒体 4的后侧还可设置两个螺紋孔， 用于固定电路 板。 本发明的电池盖设置于盒体后侧， 并釆用滑动扣合方式， 因材可釆用体 积较小的电池盖， 从而有效减小了血氧测量仪的体积。
如图 2和图 4所示， 为了使盒体 4与软胶外套 5紧密结合， 在盒体 4设 置凸缘 45 , 同时在软胶外套 5设置与凸缘 45相适配的迂回部 52。 凸缘 45 为盒体 4后侧边缘向外延伸的部分， 其中， 电池盖 3滑动方向的那侧边缘未 设置凸缘， 迂回部 52为软胶外套 5的末端往回延伸的部分， 其与软胶外套 5 的末端形成凹槽， 当将软胶外套 5装配在盒体 4上时， 凸缘 4则嵌入所述凹 槽内， 以提高盒体 4与软胶外套 5的结合力， 防止盒体 4从软胶外套 5中滑 出。
本发明的血氧测量仪由于将盒体 4分隔为并置的两个腔体， 充分利用了 盒体 4的空间， 并且电池腔仅容纳一节干电池， 比以往节省了一个干电池的 空间， 从而可釆用体积较小的盒体。 此外由于包括电路板和电池在内的电路 元件都置于盒体 4内， 从而本发明的指套式血氧测量仪装配较容易， 并且体 积较小。
可以理解的是， 以上实施方式仅仅是为了说明本发明的原理而釆用的示 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。
