Description

指夹血氧仪
技术领域
本发明涉及医疗器械技术领域，特别是，涉及一种指夹血氧仪。 
背景技术
市场上正在销售的指夹血氧仪一般都包括设有指孔上表面的上壳体和设有指孔下表面的下壳体，该上壳体和下壳体在卷簧作用下可绕一共同枢轴相互靠拢地转动，以夹紧被测量的手指，从而进行血氧饱和度的测量。 
然而，由于每个使用者手指的粗细、形状都存在着差异，因此，可能导致指夹血氧仪对被测量的手指加压不均匀，或过度被夹紧，这样，就影响了血液的正常流通，从而也就影响了测量的准确度。 
另外，即便使用者的手指定位不准确或在测量过程中无意识地使手指发生了移动，现有的指夹血氧仪也没有任何提示，这也会影响测量的准确度。 
发明内容
本发明的目的是提供一种指夹血氧仪，其在指孔内表面设有多个凸起，使得被测量的手指保持受压均匀，并且不会被过度夹紧，从而不会影响血液的正常流通，以确保测量的准确度。 
本发明的另外一个目的是提供一种指夹血氧仪，其在指孔内表面设有多个凸起，可保证被测量手指的手指肚在被测量过程中位于测量发光管处的正确的测量位置，以确保测量的准确度。为此，本发明提供了一种指夹血氧仪，包括具有指孔上表面的上壳体和具有指孔下表面的下壳体。在所述下壳体的指孔下表面，和/或所述上壳体的指孔上表面上设置有可用于支撑被测量手指的手指 肚的数个凸起；所述数个凸起位于测量发光管的周围，以保证被测量手指位于所述测量发光管的正确的测量位置。 
根据本发明的指夹血氧仪，由于在指孔内设有多个凸起，因而使得被测量的手指在测量过程中保持受压均匀，不会被过度夹紧，从而不会影响血液的正常流通；另外，在测量过程中，这些凸起可保证手指位于测量发光管处的正确的测量位置，因此，可以确保测量的准确度。 
根据本发明的指夹血氧仪，上述凸起可以辅助使用者在最初测量时将手指置于正确的位置。在测量过程中，如果使用者的手指移动了，就会造成测量不准确。根据本发明，使用者根据手指是否与凸起充分接触，就可判断其手指是否移动，从而确保测量的准确度。 
附图说明
图1是根据本发明的指夹血氧仪的横截面示意图；以及 
图2是根据本发明的指夹血氧仪下壳体的指孔下表面的结构示意图。 
具体实施方式
本发明的技术核心是：提供这样一种指夹血氧仪：即，其包括具有指孔上表面的上壳体和具有指孔下表面的下壳体，所述指孔上表面和指孔下表面围绕而成指孔内表面，在所述指孔内表面上设有可支撑被测量手指的手指肚的数个凸起。在指孔内表面设有多个凸起，使得被测量的手指保持受压均匀，并且不会被过度夹紧，从而不会影响血液的正常流通，以确保测量的准确度。同时借助于这些凸起也可以对被测量手指进行准确定位，从而进一步确保测量的准确度。 
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方式对本发明提供的指夹血氧仪进行详细描述。 
 如图1和2所示，根据本发明的指夹血氧仪10包括上壳体1、下壳体2和枢轴8。上壳体1设有上测量发光管3，下壳体2设有下测量发光管5。在下壳体1的指孔下表面上，设有数个凸起6。在被测量手指5的测量过程中，凸起6可支撑着手指肚。 
这样，在凸起6的帮助下，被测量的手指5在测量过程中保持受压均匀，不会被过度夹紧，从而不会影响血液的正常流通。特别是，该凸起6可保证手指5位于测量发光管4处的正确的测量位置，因此，可以确保测量的准确度。 
所述数个凸起6可以呈圆形、椭圆形、长圆形或多边形。 
凸起6的数量可以为3个、4个或更多，优选为4个。为了达到最佳的效果，所述数个凸起6的最小横向尺寸在0.5-1.2mm之间，优选为1.0mm。所述数个凸起6的高度在0.3-1.0mm之间，优选为0.5mm。 
特别是，各凸起6的高度和其他尺寸可以存在差异。靠近枢轴8的凸起可以略微高一点，远离枢轴8的凸起可以略微低一点，使得在测量过程中，手指更舒服。多个凸起6可相对于下壳体2的指孔下表面的纵向中心线对称地排列。由于手指肚与多个凸起6相互接触，使用者能准确判断手指在测量过程中是否有移动。因为手指出现移动将使得测量数据不准确，所以在判断出手指在测量过程中有移动后，将对手指进行重新定位，以确保测量数据的准确性。 
需要指出的是，本发明中所说的上壳体指的是使用过程中通常是面向使用者的壳体，例如带有显示屏的那一部分壳体；本发明中所说的下壳体指的是使用过程中通常是背向使用者的壳体。 
还需要指出的是，上述实施例中的多个凸起是设置在下壳体的指孔下表面并且位于测量发光管的周围，用以支撑被测量手指的手指肚。然而在实际应用中，所述多个凸起也可以设置在上壳体的指孔上表面上并位于测量发光管的周围，用以支撑被测量手指的手指肚。 
优选地，在下壳体的指孔下表面设置多个凸起并使这些凸起位于测量发光管的周围，同时，在上壳体的指孔上表面设置多个凸起并使这些凸起位于 测量发光管的周围。这样可以更好地对手指进行定位，以确保测量数据的准确性。 
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采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。
