在图2-4的实施例中，支架由通过连接部1002连接起来的第一支撑部和第二支撑部1003构成。第一支撑部包括支撑座1013、位于其上且与其可转动地连接的第一支撑件1012和受第一支撑件1012支撑的桥式结构1013。第一支撑部通过桥式结构1013与连接部1002相连，以支撑也与连接部1002相连的第二支撑部1003。其中，连接部1002被构造成使得第二支撑部1003能够在第一作用力(例如，当支架用于血栓弹力仪时，第一作用力可以为被测血液的转动所引起的旋转轴的转动对第二支撑部1003所施加的力，其中旋转轴被固定连接到第二支撑部1003)下相对于 第一支撑部转动，从而使得当与第二支撑部1003的下端固定相连的被支撑物受到外力驱动而转动时能够带动第二支撑部1003转动。
需要注意的是，为图形的清楚起见，在图2-4中并未明确示出图1中的止动机构1024。可以理解的是，止动机构1024在图2-4的示例中可以为以上提到的任一种实现方式。
在图3的示例中，第一支撑件1012包括支撑表面1012a以及位于支撑表面1012a下面并与其相连接的柱状延伸部1012b，其中，柱状延伸部1012b的顶表面尺寸小于支撑表面1012a的尺寸，即，支撑表面1012a延伸超过柱状延伸部1012b的上表面使得支撑表面1012a突出在柱状延伸部1012b的侧表面之外。在该示例中，第一支撑件1012的中心具有第一通孔1015，桥式结构1011跨过第一通孔1015被固定到第一支撑件1012上。
可以通过多种方式借助于或不借助于各种连接件来将桥式结构1011固定到第一支撑件1012。例如，可以在第一支撑件1012的支撑表面1012a上设置至少一个卡槽，并将桥式结构1011的至少一端置于所述至少一个卡槽内。还可以使用螺丝将桥式结构1011固定到第一支撑件1012。或者采用以上两种方式相结合的手段。还可以通过焊接、粘结或借助于其他连接件和/或固定件来固定桥式结构1011。
在图2-4所示的示例中，第一支撑件1012的支撑表面1012a上具有两个卡槽1017，桥式结构1011的两端分别置于两个卡槽1017内。为了进一步固定，在该示例中还采用螺钉将桥式结构1011的两端固定至第一支撑件1012。
在上面的示例中，桥式结构1011被示出为是下沉式桥式结构，其中，桥式结构1011的上表面与第一支撑件1012的支撑表面1012a基本齐平，上表面之下具有下沉部，上表面上设置有延伸至下沉部的孔口1018，用于固定连接连接部1002。本领域技术人员将认识到的是，桥式结构1011也可以采用其他结构，例如，上浮式结构，其中桥式结构1011的下表面与第一支撑件1012的支撑表面1012a基本齐平，下表面之上具有上浮部，上表面上设置有延伸至上浮部的孔口，用于固定连接连接部1002。
如图3A所示，在该示例中，支撑座1013具有顶表面1021，其上具有与第一支撑件1012的柱状延伸部1012b相匹配的凹槽或第二通孔1014，使得柱状延伸部1012b能够被容纳在该凹槽或第二通孔1014中。 可以使用多种连接手段来实现第一支撑件1012与支撑座1013的可转动连接。例如，可使用转动轴承或滑动轴承。在图2-4的示例中，在组装后，第一支撑件1012与支撑座1013直接接触，第一支撑件1012的柱状延伸部1012b被容纳在位于支撑座1013的中心的第二通孔1014中，第一支撑件1012的支撑表面1012a支撑在支撑座1013的顶表面1021上。其中，在消除了止动机构对第一支撑件1012的转动的阻止作用之后，在对第一支撑件1012施加使其旋转的适当外力时第一支撑件1012可相对于支撑座1013转动。
在图2-4的示例中将第一支撑件1012的支撑表面1012a示出为延伸超过柱状延伸部1012b的上表面，以在与支撑座1013组装后与支撑座1013的顶表面1021相接触并受到其支撑。但可以理解的是，第一支撑件1012也可以采取其他的形式，例如，支撑表面1012a的大小可以等于柱状延伸部1012b的上表面大小，在与支撑座1013组装后，凹槽或第二通孔1014的底表面接触柱状延伸部1012b的底表面并提供支撑。在这种形式中，第一支撑件为圆柱形，支撑座的凹槽或通孔具有至少部分底表面以提供对第一支撑件的支撑。
在上面的各示例中，第一支撑件1012的支撑表面1012a为圆形，柱状延伸部1012b为圆柱形，且支撑座1013也为圆柱形。本领域技术人员将理解的是，第一支撑件1012的支撑表面1012a可以为任意形状，并且柱状延伸部1012b和支撑座1013可以为其他适当的形状，只要能够实现第一支撑件1012与支撑座1013的可转动连接即可。
在图2-4所示的示例中，支撑座1013与第一支撑件1012的中心均具有通孔，并且第一通孔1015与第二通孔1014至少部分相重合，以供第二支撑部1003至少部分地穿过第一通孔1015与第二通孔1014(参见图2A-B)。可以理解的是，在第二支撑部1003无需穿过第一支撑部1001的情况下，支撑座1013与第一支撑件1012也可以不具有通孔。
在图4所示的示例中，第二支撑部1003的中心也具有通孔，即第三通孔1016。在第三通孔1016的靠近第二支撑部1003的上端的侧壁上设置有凹口1022，用于与连接部1002相连接。在图4中将第三通孔1016示出为四方形形状，可以理解的是，其可以为其他任何适当的形状。
由组装后的支架的示意图2A和2B可见，第二支撑部1003在被第一支撑部1001支撑时穿过第一支撑件1012的第一通孔1015和支撑座1013的第二通孔1014，其中第二支撑部1003的下端穿出支撑座1013。并且， 桥式结构1011穿过第二支撑部1003的第三通孔1016通过连接部1002支撑第二支撑部1003。其中，桥式结构1011上的孔口1018与第二支撑部1003上的凹口1022对准，并分别与连接部1002相连接。在组装后的支架中，连接部1002位于第二支撑部1003的第三通孔1016中。
上述支架结构和组装方式只是一种示例，可以理解的是，第二支撑部也可以不穿过第一和第二通孔，而是使得第二支撑部及其第三通孔足够大到可以使整个第一支撑部穿过第三通孔，即第三通孔的四边框均位于第一支撑部之外。
由图5的示例可见，连接部1002可以包括第一连接部1019和第二连接部1020，其中第一连接部1019与桥式结构1011固定连接(例如通过桥式结构1011上的孔口1018)，第二连接部1020与第二支撑部1003固定连接(例如通过第二支撑部1003上的凹口1022)。第一连接部1019与第二连接部1020以点接触的方式连接在一起，使得第一连接部1019与第二连接部1020能够相对转动，从而使得第二支撑部1003与桥式结构1011能够相对转动。
在图5所示的示例中，第一支撑部通过连接部支撑第二支撑部与被支撑物，连接部中的第一连接部1019与第二连接部1020通过点接触的方式连接在一起，被支撑物与第二支撑部固定相连并在受到外力驱动后驱动第二支撑部1003绕第一连接部1019与第二连接部1020之间的接触点转动。由于第一连接部1019与第二连接部1020通过点接触的方式连接在一起，在第一支撑部1001与第二支撑部1003发生相对转动时仅有一个接触点产生摩擦力阻碍第二支撑部1003的转动，可以减小支架上产生的摩擦力，从而减小被支撑物旋转时受到的旋转阻力。
在本发明的实施例中，点接触的方式可以是：两个接触部件之间不是完全接触，且接触面积小于预定值。比如，上述第一连接部1019与第二连接部1020通过点接触的方式连接在一起时，接触面积小于1平方毫米。
图6示出了第一连接部和第二连接部为宝石轴承3031和顶锥3032的连接部示意图。宝石轴承3031设置有锥形凹槽2011，顶锥3032为锥状结构，顶锥3032的尖端位于宝石轴承3031上的锥形凹槽2011内，顶锥3032与宝石轴承3031以点接触形式相接合。
如图6所示，宝石轴承3031为圆饼状结构，在宝石轴承3031的一个平面上设置有一个锥形凹槽2011，顶锥3032为锥状结构。顶锥3032的 尖端位于凹槽2011内，仅顶锥3032的尖端与凹槽2011的底部相接触，实现宝石轴承3031与顶锥3032通过点接触的形式进行连接。比如，顶锥3032的尖端具有0.8平方毫米的面积，通过该0.8平方毫米面积的尖端与宝石轴承3031的锥形凹槽2011点接触。
在本发明一个实施例中，连接部中的第一连接部为宝石轴承，第二连接部为顶锥。在另一实施例中，第一连接部为顶锥而第二连接部为宝石轴承。
在图7所示的示例中，宝石轴承3031作为第一连接部与第一支撑部1001固定连接，顶锥3032作为第二连接部与第二支撑部1003固定连接，顶锥3032的尖端位于宝石轴承3031的凹槽内，顶锥3032的尖端与宝石轴承3031凹槽的底部为点接触。第一支撑部1001通过宝石轴承3031支撑固定连接的顶锥3032及第二支撑部1003。
在图8所示的实施例中，顶锥3032作为第一连接部与第一支撑部1001固定连接，宝石轴承3031作为第二连接部与第二支撑部1003固定连接，顶锥3032的尖端与宝石轴承3031的底部为点接触。第一支撑部1001通过顶锥3032支撑固定连接的宝石轴承3031及第二支撑部1003。
在本发明的一个实施例中，支架进一步包括：至少一对磁铁；
对于每一对磁铁，该对磁铁中的第一磁铁固定于第一支撑部上靠近第二支撑部的一侧，该对磁铁中的第二磁铁固定于第二支撑部上靠近第一支撑部的一侧；以及
第一磁铁与第二磁铁平行叠放，且相接近的两个面为同性磁极。
在图9所示的示例中，支架包括两对磁铁，第一对磁铁包括磁铁5041及磁铁5042，第二对磁铁包括磁铁5051及磁铁5052，磁铁5041及磁铁5051固定于第一支撑部1001上，磁铁5042及磁铁5052固定于第二支撑部1003上。第一对磁铁中的磁铁5041与磁铁5042平行叠放，磁铁5041与磁铁5042相互靠近的面具有相同极性的磁极，例如，磁铁5041的N极指向第二支撑部1003，磁铁5042的N极指向第一支撑部1001；第二对磁铁中的磁铁5051与磁铁5052平行叠放，磁铁5051与磁铁5052相互靠近的面具有相同极性的磁极，例如，磁铁5051的S极指向第二支撑部1003，磁铁5052的S极指向第一支撑部1001。
在图5的示例中，支架还包括用于支撑第一支撑部1001和第二支撑部1003的固定立柱1023，其中支撑座1013固定连接至固定立柱1023。
在上面所述的支架的各实施例中，第二支撑部能够在施加到其的第 一作用力下相对于第一支撑部(例如第一支撑部的桥式结构)转动，从而使得当第二支撑部下端连接有被支撑物时被支撑物的转动可带动第二支撑部一起相对于第一支撑部转动。在未消除止动机构对可动结构的转动的阻止作用的情况下，第一支撑部保持不动，由此可通过测量第二支撑部的转动角度来测量被支撑物的转动角度。在需要时(例如在需要调整第一支撑部与第二支撑部之间的角度关系以提高测量精度时)，可消除止动机构对转动的阻止作用(例如，松开固定件、抵消摩擦力和/或粘滞力等)，之后可转动结构能够在施加到其的第二作用力下相对于第二支撑部转动(例如，第一支撑件能够在施加到其的第二作用力下带动桥式结构相对于第二支撑部转动)，从而使得可通过手动转动可转动结构(例如第一支撑件)来使第一支撑部(例如桥式结构)与第二支撑部处于预定的位置关系，以确保测量的准确性。一般地，为便于测量，需将第一支撑部和第二支撑部布置为使得桥式结构的长度方向的轴线垂直于第二支撑部的平面。当发现第一支撑部的桥式结构与第二支撑部偏离了该预定位置关系时，需要将其调整到该预定关系以保证测量准确性。在这种情况下，通过根据本发明的包括可旋转桥式结构的支架，可以在消除了止动机构对转动的阻止作用之后对第一支撑件施加适当的外力以使其及与其固定相连的桥式结构相对于第二支撑部旋转一定角度，从而使得其上的桥式结构的轴线变得垂直于第二支撑部。
本文中的术语“桥式结构”是指该结构是跨越支撑其的表面的结构，需要指出的是，支撑其的表面可以具有供桥式结构跨越的开槽、开口或通孔，但这些开槽、开口、通孔或类似结构并不是必需的。
本文所述的支架的各个实施例可用于血栓弹力仪。图5示出了包括上面所述的支架的血栓弹力仪的一个实施例。如图5所示，该血栓弹力仪包括支架以及作为受支架支撑的被支撑物的旋转轴7。第二支撑部1003的下端与旋转轴7的一端相连接以支撑旋转轴7，使得旋转轴7能够在外部驱动作用下转动。在使用时，旋转轴7的另一端(下端)伸入容纳在容器中的被测血液中，血液被驱动装置驱动得旋转，从而带动旋转轴7也转动。该血栓弹力仪通过测量旋转轴7的转动角度，可以计算出被测血液的血凝参数数据。
在本发明的一个实施例中，血栓弹力仪还包括测量装置，其中所述测量装置用于对所述旋转轴的转动角度进行测量，并根据所述旋转轴的转动角度形成对应于所述被测血液的血栓弹力图。
在图10所示的示例中，所述测量装置包括：至少一个反光片51、至少一个光发射模块52、至少一个光接收模块53及处理模块54；
旋转轴7与至少一个反光片51固定连接，旋转轴7在外部驱动作用下带动至少一个反光片51转动；
每一个光发射模块52，用于以固定的方向向对应的反光片51发射光；
每一个反光片51，用于接收对应光发射模块52发射的光，并对接收到的光进行反射；
每一个光接收模块53，用于以固定的方向接收对应的反光片51反射的光，根据光的强度将接收到的光转换为对应的电信号，并将电信号传输给处理模块54；
处理模块54，用于对至少一个光接收模块53转换成的电信号进行处理，以确定旋转轴7的转动角度。
根据该实施例的血栓弹力仪，反光片将光发射模块发射的光反射给光接收模块，当反光片在旋转轴的带动下发生转动时，由于光发射模块以固定的方向发射光，反光片接收到的光的量发生改变，同时由于反光片的转动，反光片反射光的光路发生改变，导致以固定的方向接收光的光接收模块接收到的光的强度发生改变，光接收模块根据光的强度将接收到的光转换为对应的电信号，处理模块根据电信号确定旋转轴的转动角度。这样，以光为检测旋转轴转动角度的信号，由于光的强度不会随温度等外界因素的改变而发生变化，因而通过光检测旋转轴的转动角度，可以提高对旋转轴转动角度进行检测的准确性。
在图11所示的示例中，光发射模块52包括发光二极管6031及导光柱6032，其中，发光二极管6031通过导光柱6032向反光片51发射光；
和/或：
光接收模块53包括光电池6041及导光柱6042，其中，光电池6041通过导光柱6042接收反光片51发射的光。
在本发明实施例中，由于光发射模块52所位于的第四通孔6062的内表面为机械加工表面，存在一定的粗糙度，如果通过发光二极管6031直接向反光片51发射光，发光二极管6031发出的光会在第四通孔6062内发生漫反射，一方面造成光能的散失，另一方面造成从第四通孔6062射出的光的方向及量难以控制。通过导光柱6032将发光二极管6031发出的光射向反光片51，发光二极管6031发出的光在导光柱6032内部传导， 光不会产生漫反射的现象，从而提高光能的利用率，并保证从第四通孔6062射出的光具有特定的方向和特定的量，进而保证对旋转轴7转动角度进行检测的准确性。
在本发明一个实施例中，每一个光接收模块包括有一个光电池和一个导光柱，光电池和导光柱均固定在第五通孔内，其中导光柱位于靠近反光片的一侧。导光柱以固定的方向接收对应反光片反射的光，并将接收到的光传导给光电池，光电池根据接光的强度将接收到的光转换成对应的电信号。
在图11所示的示例中，由于第五通孔6063也通过机械加工而成，因而第五通孔6063内表面存在一定的粗糙度，如果反光片51反射的光直接进入第五通孔6063而达到光电池6041，光会在第五通孔6063的内壁上发生漫反射，造成光能量的散失，最终达到光电池6041的光的能量小于反光片射入第五通孔6063的光的能量，进而造成最终检测到的旋转轴7的转动角度存在较大误差。通过导光柱6042接收反光片51反射的光，光在导光柱6042内部传输，在传输过程中光不会发生漫反射，保证光电池6041接收到的光的能量与反光片51反射给导光柱6042的光的能量相等，从而可以保证对旋转轴7的转动角度进行检测的准确性。
在本发明的一个实施例中，血栓弹力仪还包括有至少一个挡光片，挡光片的数量与导光柱的数量相等，每一个挡光片对应一个导光柱。挡光片上设置有固定形状及固定尺寸的通光孔，挡光片设置于反光片与导光柱之间，使反光片反射的光仅能够通过挡光片上的通光孔发射给导光柱。
图12示出根据本发明一个实施例的使用上述血栓弹力仪的方法的流程图。如图12所示，该方法包括：
步骤S121：响应于所述第一支撑部相对于所述第二支撑部偏离预定位置，消除所述止动机构的所述阻止作用；
步骤S122：通过对所述第一支撑件施加第二作用力来使所述第一支撑件转动，从而使得所述桥式结构相对于所述第二支撑部转动为与所述第二支撑部成预定角度的位置；
步骤S123：使所述旋转轴的下端插入被测血液中；
步骤S124：使所述被测血液旋转以带动所述旋转轴转动；以及
步骤S125：基于所测量的所述旋转轴的转动角度来计算被测血液的血凝数据。
虽然上面以支架用于血栓弹力仪为例进行了说明，但可以认识到的是，本发明各实施例的支架也可用于其他被支撑物以组成支撑系统。图13示出了这样的支撑系统的组成框图。如图13所示，该支撑系统包括支架1301和被支撑物1302，其中支架1301的第二支撑部的下端与被支撑物1302的一端相连接以支撑被支撑物1302，使得被支撑物1302能够在外部驱动作用下转动。
本发明提供的各个实施例，至少具有如下有益效果：
1、在本发明实施例中，第二支撑部能够在施加到其的第一作用力下相对于第一支撑部转动，从而使得当第二支撑部下端连接有被支撑物时被支撑物的转动可带动第二支撑部一起相对于第一支撑部转动。在未消除止动机构对可动结构的转动的阻止作用的情况下，第一支撑部保持不动，由此可通过测量第二支撑部的转动角度来测量被支撑物的转动角度。在需要时(例如在需要调整第一支撑部与第二支撑部之间的角度关系以提高测量精度时)，可消除止动机构对转动的阻止作用(例如，松开固定件、抵消摩擦力和/或粘滞力等)，之后可转动结构能够在施加到其的第二作用力下相对于第二支撑部转动，从而使得可通过手动转动可转动结构(例如第一支撑件)来使第一支撑部(例如桥式结构)与第二支撑部处于预定的位置关系，以确保测量的准确性。
2、在本发明实施例中，第一支撑部通过连接部支撑第二支撑部与被支撑物，连接部中的第一连接部与第二连接部通过点接触的方式连接在一起，被支撑物受力后驱动第二支撑部绕第一连接部与第二连接部之间的接触点转动。由于第一连接部与第二连接部通过点接触的方式连接在一起，在第二支撑部与第一支撑部发生相对转动时仅有一个接触点产生摩擦力阻碍第二支撑部的转动，可以减小支架上产生的摩擦力，从而减小被支撑物旋转时受到的旋转阻力。
3、在本发明实施例中，连接部包括的两个连接部可以为宝石轴承和顶锥，顶锥的尖端位于宝石轴承的锥形凹槽内，顶锥的尖端与锥形凹槽的底部为点接触，宝石轴承与顶锥发生相对转动时，产生的摩擦力较 小，从而可以减小被支撑物旋转时受到的来自支架的旋转阻力，当该支架应用于血栓弹力仪时可以提高血栓弹力仪的灵敏度及测量的准确性。
4、在本发明实施例中，支架可以包括至少一对磁铁，每一对磁铁中的一个磁铁固定于第一支撑部上，另一个磁铁固定于第二支撑部上，一对磁铁平行叠放且同性磁极相对，这样，根据同性相斥的原理，第一支撑部上的磁铁给第二支撑部上的磁铁一个向上的磁力，该磁力可以减小第一连接部与第二连接部点接触之间的压力，减小点接触之间的压力可以进一步减小点接触产生的摩擦力，从而进一步减小被支撑物旋转时受到的旋转阻力。
5、本发明实施例中，反光片将光发射模块发射的光反射给光接收模块，当反光片在旋转轴的带动下发生转动时，由于光发射模块以固定的方向发射光，反光片接收到的光的量发生改变，同时由于反光片的转动，反光片反射光的光路发生改变，导致以固定的方向接收光的光接收模块接收到的光的强度发生改变，光接收模块根据光的强度将接收到的光转换为对应的电信号，处理模块根据电信号确定旋转轴的转动角度。这样，以光为检测旋转轴转动角度的信号，由于光的强度不会随温度等外界因素的改变而发生变化，因而通过光检测旋转轴的转动角度，可以提高对旋转轴转动角度进行检测的准确性。
6、本发明实施例中，发光二极管通过导光柱发射光，光电池通过导光柱接收光，导光柱作为光的通道可以增强光的均匀性，并避免光在固定发光二极管或光电池的通孔内发生漫反射，对光光的强度造成影响的情况发生，从而保证对旋转轴转动角度进行检测的准确性。
需要注意的是，本文中出现的“处理器”、“处理单元/模块”、“控制器”、“控制单元/模块”或类似术语是指能够执行适当的程序指令、运算操作、数据处理和/或控制操作等的适当装置，它们可以为软件、硬件、固件或它们的组合，诸如例如计算机、中央处理单元等。它们可以由单个的部件构成，也可以是其功能分散在多个部件上的情况。其可以是集中式处理系统，也可以是分布式处理系统。
