如图1至图3所示，压迫器包括调压板1以及连接在调压板1两端的固定带2，调压板1的中心穿设有调节螺孔(图中未示出)，调节螺杆3旋接在调节螺孔内，调节螺杆3的上端连接有调节螺母4，调节螺杆3的下端设置有用于压迫桡动脉6穿刺部位的压力板7。压迫器通过固定带2绑定在人的手臂后，通过旋转调节螺母4可以使压力板7上下移动，将压力板7对准桡动脉6的穿刺部位，进而对桡动脉6的穿刺部位进行压迫止血。
在本发明中，调节螺母4直接设置在调节螺杆3的上端进行调节。当然，调节螺母4也可以垂直于调节螺杆3，通过齿轮传动机构连接 调节螺杆3，进而带动调节螺杆3上下移动。
优选的，调压板1和压力板7可以是透明的，也可以是半透明或有色透明，方便观察穿刺部位是否出血。
在调压板1的前端还连接有监测板8，调压板1的前端是指压力板7靠近手掌的一端。监测板8的下表面设置有用于监测桡动脉6是否闭塞的监测模块，因桡动脉6上的穿刺部位经过压力板7压迫止血后，压力板7压迫过紧可能会造成桡动脉6闭塞，该监测模块能够在止血的过程中，指导非闭塞性压迫，检测急性及慢性桡动脉闭塞，进而方便医护人员调整压迫器，避免发生桡动脉闭塞的现象。
优选的，在监测板8的下表面设置有弹性凸起82，监测模块嵌设在弹性凸起82的下表面，方便与桡动脉6相接触。
优选的，弹性凸起82可以是橡胶、海绵等材质，具有一定的弹性。
进一步的，监测板8的上表面设置有控制装置5，控制装置5的内部设置有控制模块51，调压板8上还穿设有过线孔81，信号线缆穿过过线孔连接控制模块51和监测模块。
控制装置5的上表面设置有显示模块52，显示模块52与控制模块51电连接。
控制装置5的内部还设置有报警模块53，控制模块51与报警模块53电连接，当监测模块监测到桡动脉6闭塞后，控制模块51通过报警模块53进行报警提示，以方便医护人员对压力板7进行调节减压。
进一步的，控制装置5内可以设置蓝牙模块，控制模块51通过蓝牙模块可以连接移动设备端(智能手机等移动设备)，通过蓝牙将脉搏波发送至移动设备端进行监控。
进一步的，控制装置5内还设置有电源模块54，电源模块54用于向控制装置5内各个模块进行供电。
作为本发明的第一个实施例，如图1至图3，监测模块包括柯氏音提取模块9，柯氏音提取模块9用于提取桡动脉6振动产生的柯氏 音，柯氏音提取模块9通过第一信号线缆91电连接控制装置5内的控制模块51，控制模块51设置有处理器和柯氏音处理电路，柯氏音信号经过柯氏音处理电路连接到处理器进行处理，去掉噪声信号，提取到完整的柯氏音信号。控制装置5的内部还设置有扩音模块92，控制模块51通过扩音模块92播放柯氏音，还通过显示模块52显示柯氏音波形，即通过观察柯氏音波形也能够判断桡动脉6是否闭塞。
若桡动脉6闭塞，柯氏音提取模块9无法提取柯氏音，表明压力板7对穿刺部位的压力过大，需要医护人员进行调整；若桡动脉6没有闭塞，桡动脉6内有血液流过，桡动脉6发生振动产生柯氏音，通过该方式能够判断桡动脉6是否存在闭塞。
控制模块51与扩音模块92之间电连接有柯氏音开关93，柯氏音开关93设置在控制装置5的上表面，通过按压柯氏音开关93能够开启或关闭柯氏音的播放。
优选的，柯氏音提取模块9可以是柔性传感器，具有良好的柔韧性、延展性。
优选的，作为本发明的第二个实施例，与第一个实施例相同的部分则不再赘述。如图4至图6所示，监测模块包括光电容积脉搏波检测模块10，光电容积脉搏波检测模块10用于采集桡动脉6的脉搏信号。光电容积脉搏波检测模块10能够将一定波长的光束照射到桡动脉6，获得容积脉搏血流的变化(可以是氧饱和度、脉搏波)。脉搏波所表现出的形态(波的形状)、强度(波的幅值)、速率(波的速度)与节律(波的周期)等方面的特征信息在相当程度上反映出桡动脉6是否存在闭塞。
光电容积脉搏波检测模块10通过第二信号线缆101电连接控制装置5内的控制模块51，控制模块51通过显示模块52显示脉搏波，即通过观察脉搏波能够判断桡动脉6是否闭塞。
优选的，光电容积脉搏波检测模块10可以是柔性传感器，具有良好的柔韧性、延展性。
优选的，作为本发明的第三个实施例，与第一个实施例相同的部 分则不再赘述。如图7和图8所示，监测模块包括压电感受器11，压电感受器11用于采集桡动脉6的脉搏信号，压电感受器11通过第三信号线缆111电连接控制装置5内的控制模块51，控制模块51通过显示模块52显示脉搏波，即通过观察脉搏波能够判断桡动脉6是否闭塞。
优选的，压电感受器11可以是柔性传感器，具有良好的柔韧性、延展性。
优选的，作为本发明的第四个实施例，与第一个实施例相同的部分则不再赘述。如图9和图10所示，监测模块包括压阻感受器12，压阻感受器12用于采集桡动脉6的脉搏信号，压阻感受器12通过第四信号线缆121电连接控制装置5内的控制模块51，控制模块51通过显示模块52显示脉搏波，即通过观察脉搏波能够判断桡动脉6是否闭塞。
优选的，压阻感受器12可以是柔性传感器，具有良好的柔韧性、延展性。
优选的，作为本发明的第五个实施例。如图11和图12所示，监测模块包括柯氏音提取模块9和光电容积脉搏波检测模块10(被柯氏音提取模块9遮挡，图中未示出)，柯氏音提取模块9和光电容积脉搏波检测模块10沿着桡动脉6的方向并排设置。即在第一个实施例的基础上，监测模块还包括光电容积脉搏波检测模块10。
柯氏音提取模块9用于提取桡动脉6振动产生的柯氏音，柯氏音提取模块9通过第一信号线缆91电连接控制装置5内的控制模块51。控制模块51设置有处理器和柯氏音处理电路，柯氏音信号经过柯氏音处理电路连接到处理器进行处理，去掉噪声信号，提取到完整的柯氏音信号。控制装置5的内部还设置有扩音模块92，控制模块51通过扩音模块92播放柯氏音。若桡动脉6闭塞，柯氏音提取模块9无法提取柯氏音，表明压力板7对穿刺部位的压力过大，需要医护人员进行调整；若桡动脉6没有闭塞，桡动脉6内有血液流过，桡动脉6发生振动产生柯氏音，通过该方式能够判断桡动脉6是否存在闭塞。
光电容积脉搏波检测模块10则用于采集桡动脉6的脉搏信号，光电容积脉搏波检测模块10能够将一定波长的光束照射到桡动脉6，获得容积脉搏血流的变化(可以是氧饱和度、脉搏波)。脉搏波所表现出的形态(波的形状)、强度(波的幅值)、速率(波的速度)与节律(波的周期)等方面的特征信息在相当程度上反映出桡动脉6是否存在闭塞。
光电容积脉搏波检测模块10通过第二信号线缆101电连接控制装置5内的控制模块51。控制模块51通过显示模块52显示脉搏波和柯氏音波形。
在本实施例中，综合柯氏音提取模块9获取桡动脉6的柯氏音以及光电容积脉搏波检测模块10采集桡动脉6的脉搏信号来判断桡动脉6是否存在闭塞，进一步提高了对绕动脉6是否存在闭塞的精准性。并且当柯氏音提取模块9或光电容积脉搏波检测模块10其中一个模块出现故障或者监测不准确时，另一个仍然可以监测桡动脉6是否闭塞。
优选的，柯氏音提取模块9和光电容积脉搏波检测模块10均可以是柔性传感器，具有良好的柔韧性、延展性。
本发明中的柯氏音提取模块9、光电容积脉搏波检测模块10、压电感受器11、压阻感受器12既可以以单一的方式进行监测桡动脉6是否存在闭塞，可以相互组合实现共同监测桡动脉6是否闭塞。当然，本发明中的柯氏音提取模块9、光电容积脉搏波检测模块10、压电感受器11、压阻感受器12也可应用在其他不同类型的压迫器中，对压迫器进行止血的过程中，指导非闭塞性压迫，检测急性及慢性桡动脉闭塞。
由此可见，本发明公开了一种压迫器，包括调压板以及连接在调压板两端的固定带，调压板的中心穿设有调节螺孔，调节螺杆旋接在调节螺孔内，调节螺杆的上端连接有调节螺母，调节螺杆的下端设置有用于压迫桡动脉穿刺部位的压力板；调压板的前端还连接有监测板，监测板的下表面设置有用于监测桡动脉是否闭塞的监测模块。监 测模块包括柯氏音提取模块，柯氏音提取模块用于提取桡动脉振动产生的柯氏音，柯氏音提取模块电连接控制装置内的控制模块，控制装置的内部还设置有扩音模块，控制模块通过扩音模块播放柯氏音，还通过显示模块显示柯氏音波形。本发明能够在桡动脉通过压迫器进行止血的过程中，指导非闭塞性压迫，检测急性及慢性桡动脉闭塞。
