本发明的技术核心是：提供这样一种指夹式血氧测量仪，其包括上壳体、 下壳体、 枢轴以及连接在上壳体和下壳体之间的弹性连接件， 当上壳体和下 壳体绕枢轴旋转而彼此分离时， 弹性连接件被拉伸并产生弹性形变， 借助于 该弹性形变而在上 /下壳体之间产生夹持力， 以夹持被测手指。 其中， 该弹性 连接件可以釆用硅胶、 牛筋或弹簧等制成。
为使本技术领域的人员更好地理解本发明的技术方案， 下面结合附图和 具体实施例对本发明提供的指夹式血氧测量仪进行详细描述。
请参阅图 1 , 其中示出了本发明第一实施例提供的指夹式血氧测量仪。 如图所示， 该血氧测量仪包括具有指孔上表面的上壳体 1、 具有指孔下表面 的下壳体 2、 枢轴 3以及弹性连接件 4。
其中， 上壳体 1、 下壳体 2彼此相对设置并可绕枢轴 3旋转而彼此分离 呈张开状， 或者绕枢轴 3旋转而彼此扣合呈闭合状。 通常， 在上壳体 1内设 置有数据处理电路板、 显示屏、 接收电路板。 下壳体 2内设置有发光电路板 和该血氧测量仪的工作电源（例如， 电池）。 其中， 接收电路板与发光电路板 相互配合完成血氧值数据的釆集， 数据通信接口可在上壳体 1或者下壳体 2 上， 以使上壳体 1和下壳体 2通过电气连接而相互通信。
需要指出的是， 本发明中所说的上壳体指的是设置有显示屏的那一壳 体， 相应地， 下壳体则是指与所述上壳体相扣合的那一壳体。 上壳体和下壳 体彼此相向的内侧面呈凹陷形， 籍此， 上壳体 1和下壳体 2可围成指孔 5 , 用以容纳被测手指。
所述弹性连接件 4为折扇形弹性连接件， 并连接在上壳体 1和下壳体 2 之间。 当上壳体 1和下壳体 2处于张开状态时， 折扇形弹性连接件 4因受到 来自上壳体 1和下壳体 2的拉力而处于拉伸状态， 并且为反抗所述拉力而存 在可使上壳体 1和下壳体 2彼此闭合的收缩力， 即， 折扇形弹性连接件 4向 上壳体 1和下壳体 2施加了可使二者彼此闭合的收缩力， 上壳体 1和下壳体 2就是借助于该收缩力而实现对被测手指的夹持， 以使血氧测量仪不易脱落， 并进行血氧测量。 当上壳体 1和下壳体 2处于闭合状态时， 折扇形弹性连接 件 4可以处于自由状态， 即放^ ^状态或折叠状态， 此时该折扇形弹性连接件 4的各折叠层彼此层叠在一起并置于上 /下壳体内， 既不会受到来自上壳体 1 和下壳体 2的拉力， 也不会受到挤压力。 当然， 也可以这样设置弹性连接件 4, 当上壳体 1和下壳体 2处于闭合状态时，折扇形弹性连接件 4仍处于拉伸 状态， 也就是说， 连接在上壳体 1和下壳体 2之间的折扇形弹性连接件 4始 终处于拉伸状态， 只是在上壳体 1和下壳体 2处于闭合状态时， 该折扇形弹 性连接件 4处于较小的拉伸程度，而在上壳体 1和下壳体 2处于张开状态时， 该折扇形弹性连接件 4处于较大的拉伸程度。 请一并参阅图 2和图 3 , 其中分别示出了折扇式弹性连接件处于折叠状 态和拉伸状态时，沿手指伸入方向所看到的折扇式弹性连接件的形状示意图。
如图 2所示， 当本实施例提供的指夹式血氧测量仪的上壳体和下壳体处 于闭合状态时， 该折扇式弹性连接件 4处于放 ^^状态（即， 折叠状态）， 其中 的各个折叠层彼此层叠在一起， 因而， 此时的折扇式弹性连接件 4形状类似 于一个折叠收拢起来的折扇。
如图 3所示， 当本实施例提供的指夹式血氧测量仪的上壳体和下壳体处 于张开状态时， 该折扇式弹性连接件 4处于拉伸状态， 其中的各折叠层被拉 伸而展开并产生弹性形变， 因而， 此时的折扇式弹性连接件 4形状类似于一 个撑开的折扇。 此时， 为反抗所述拉力和形变而存在可使上壳体和下壳体彼 此闭合的收缩力，借助于该收缩力可实现对被测手指的夹持并进行血氧测量。
在本实施例中， 该折扇式弹性连接件 4的材料可以选择质地结实、 能够 经受频繁拉伸并不易破裂损坏的弹性材质， 如硅胶， 牛筋等。
至于折扇式弹性连接件 4与上 /下壳体的连接固定方式，可以釆用不可拆 卸连接方式来固定到上壳体 1和下壳体 2上， 例如， 通过将折扇式弹性连接 件 4粘结在上壳体 1和下壳体 2的内侧边缘而将其直接固定在上 /下壳体上。 或者， 也可以釆用可拆卸的连接方式而将其连接到上壳体 1和下壳体 2上， 例如， 在折扇式弹性连接件 4 的上 /下边缘设有硬滑板 23 , 同时在上壳体 1 和下壳体 2上设置与该弹性连接件 4的硬滑板 23相匹配的滑槽，通过将该硬 滑板 23嵌入到滑槽中而实现该折扇式弹性连接件 4与上壳体 1和下壳体 2 的固定； 再如， 在折扇式弹性连接件 4的上 /下边缘设置挂杆， 并在上壳体 1 和下壳体 2上设置与该弹性连接件 4的挂杆相匹配的卡扣， 通过将该挂杆卡 入到卡扣中而实现该折扇式弹性连接件 4与上壳体 1和下壳体 2的固定。
在本实施例中，由于釆用了诸如硅胶等材料制成的折扇式弹性连接件 44 代替现有技术中通常釆用的扭转弹簧， 因而， 本实施例提供的血氧测量仪不 会发生卡簧现象。 而且， 由于该弹性连接件 4并非设置在枢轴附近， 因而对 被测手指施加的夹持力相对均勾， 并可保证血液正常流通， 从而进一步保证 测量结果的准确性。此外，相对均匀的夹持力也不会使被测手指感觉不舒适。
优选地，本实施例提供的血氧测量仪还可以设置遮光板 13 , 以便在该血 氧测量仪的上壳体 1和下壳体 2处于张开状态时，由所述遮光板 13来遮挡侧 面进光， 以减小甚至避免侧面进光对测量结果产生影响， 这进一步保证了测 量结果的准确性。 事实上， 遮光板 13可以是在上壳体 1和 /或下壳体 2的侧 边上另外附加一块板材来实现， 也可以是将上壳体 1 的侧边 13向下壳体 2 方向延长或者是将下壳体 2的侧边向上壳体 1方向而实现。
优选地， 在本实施例提供的血氧测量仪中， 在指孔内表面 （即， 在指孔 内由指孔上表面和指孔下表面围绕而形成的表面）上设有可支撑被测手指的 手指肚的数个凸起，这些凸起可使被测手指受压更为均匀且不会被过度夹紧， 从而确保被测手指中的血液正常流通， 这进一步保证测量准确度。 同时， 借 助于这些凸起也可以对被测手指进行准确定位， 从而进一步确保测量的准确 度。
请一并参阅图 4至图 7 , 其中， 图 4示出了本发明第二实施例提供的指 夹式血氧测量仪； 图 5示出了本发明第三实施例提供的指夹式血氧测量仪； 图 6示出了本发明第四实施例提供的指夹式血氧测量仪； 图 7示出了本发明 第五实施例提供的指夹式血氧测量仪。

第一至第五实施例之间的差别仅在于上述弹性连接件 4的具体形状和结 构， 下面结合图 4至图 7详细说明第二至第五实施例中的弹性连接件 4。 如图 4所示， 在本发明第二实施例提供的指夹式血氧测量仪中， 弹性连 接件 4设置在该血氧测量仪的两侧， 并连接上壳体 1和下壳体 2。 其中， 每 一侧所设置的弹性连接件 4均为一个整体的带状弹性件 4(亦称为弹性带 4 ), 该带状弹性件 4的宽度较宽， 可从靠近枢轴 3的位置起， 沿着与手指伸入方 向相反的方向而延伸至指孔 5的入口位置附近， 并且在上壳体 1和下壳体 2 处于张开状态时， 该带状弹性件 4因受到来自上壳体 1和下壳体 2的拉力而 处于拉伸状态并呈平面状。
需要指出的是， 在实际应用中， 带状弹性件 4的宽度不作特别限定， 可 以根据实际需要而定。 该带状弹性件 4的材料可以选择质地结实、 能够经受 频繁拉伸并不易破裂损坏的材质， 如硅胶等。 至于该带状弹性件 4与上壳体 1和下壳体 2之间的连接固定方式及其与上壳体 1/下壳体 2协同工作而夹持 被测手指的工作原理， 类似于前面结合第一实施例所作的说明， 在此不再赘 述。
如图 5所示， 在本发明第三实施例提供的指夹式血氧测量仪中， 弹性连 接件 4设置在该血氧测量仪的两侧， 并连接上壳体 1和下壳体 2。 其中， 每 一侧所设置的弹性连接件 4均包括 5根条状弹性件 4, 这样布置这些条状弹 性件 4: 即， 沿着与手指伸入方向相反的方向而从靠近枢轴 3的位置起至靠 近指孔 5的入口位置止， 使这 5根条状弹性件依次并行连接在上壳体 1和下 壳体 2之间， 并且在上壳体 1和下壳体 2处于张开状态时， 这些条状弹性件 4因受到来自上壳体 1和下壳体 2的拉力而处于拉伸状态， 且这 5根条状弹 性件 4的长度沿手指伸入方向而逐一递减。
需要指出的是， 在实际应用中， 条状弹性件 4的数量可以不局限于本实 施例中所述的 5条， 并且各条状弹性件 4的宽度及彼此之间的间距可以根据 实际需要而定。 本实施例中， 条状弹性件 4的材料可以釆用质地结实、 能够 经受频繁拉伸并不易破裂损坏的材质， 如硅胶、 牛筋等。 至于这些条状弹性 件 4与上壳体 1和下壳体 2之间的连接固定方式及与上壳体 1/下壳体 2协同 工作而夹持被测手指的工作原理， 类似于前面结合第一实施例所作的说明， 在此不再赘述。
如图 6所示， 在本发明第四实施例提供的指夹式血氧测量仪中， 弹性连 接件 4设置在该血氧测量仪的两侧， 并连接上壳体 1和下壳体 2。 其中， 每 一侧所设置的弹性连接件 4均为一根连接在上壳体 1和下壳体 2之间的可拉 伸的绳状弹性件 4。
需要指出的是， 本实施例中所述的绳状弹性件 4包括可拉伸的实心的弹 性绳、 弹性棒等， 也包括可拉伸的空心的弹性管。 并且， 该绳状弹性件 4可 以釆用质地结实、 能够经受频繁拉伸并不易破裂损坏的材质， 如硅胶、 牛筋 等。
在实际应用中， 该指夹式血氧测量仪每一侧的绳状弹性件 4的数量可以 不局限于本实施例中所述的 1条， 并且其粗细程度可以根据实际需要而定。 至于该绳状弹性件 4与上壳体 1和下壳体 2之间的连接固定方式及与上壳体 1/下壳体 2协同工作而夹持被测手指的工作原理， 类似于前面结合第一实施 例所作的说明， 在此不再赘述。
如图 7所示， 在本发明第五实施例提供的指夹式血氧测量仪中， 弹性连 接件 4设置在该血氧测量仪的两侧， 并连接上壳体 1和下壳体 2。 其中， 每 一侧所设置的弹性连接件 4均为一根连接在上壳体 1和下壳体 2之间的弹簧 4。
需要指出的是， 在实际应用中， 该指夹式血氧测量仪每一侧的弹簧 4的 数量可以不局限于本实施例中所述的 1条， 而是可以根据实际需要而定。 至 于该弹簧 4与上壳体 1和下壳体 2之间的连接固定方式及与上壳体 1/下壳体 2 协同工作而夹持被测手指的工作原理， 类似于前面结合第一实施例所作的 说明， 在此不再赘述。
请参阅图 8, 其中示出了本发明第六实施例提供的指夹式血氧测量仪。 如图所示， 该血氧测量仪包括具有指孔上表面的上壳体、 具有指孔下表面的 下壳体、 枢轴 3以及弹性连接件 4。 其中， 上壳体和下壳体彼此相对设置并 可绕枢轴 3旋转而彼此分离呈张开状， 或者绕枢轴 3旋转而彼此扣合呈闭合 状。 至于上壳体和下壳体中的电气部件的设置位置及彼此之间的连接关系， 类似于前面结合图 1所作的说明， 在此不再赘述。
