图10是根据本发明一种压迫器中第八个实施例的示意图。
具体实施方式
为了便于理解本发明，下面结合附图和具体实施例，对本发明进行更详细的说明。附图中给出了本发明的较佳的实施例。但是，本发明可以以许多不同的形式来实现，并不限于本说明书所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解 更加透彻全面。
需要说明的是，除非另有定义，本说明书所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是用于限制本发明。本说明书所使用的术语“和/或”包括一个或多个相关的所列项目的任意的和所有的组合。
如图1所示，作为本发明压迫器的第一个实施例。压迫器包括第一固定带1和设置在第一固定带1上的压迫气囊2，压迫气囊2具体设置在第一固定带1的内侧面，即第一固定带1贴紧手腕的那一侧；第一固定带1用于缠绕在手腕上，第一固定带1上表面的右侧边缘设置有魔术贴的雄侧，第一固定带1下表面的左侧边缘设置有魔术贴的雌侧，将第一固定带1缠绕手腕后可以通过雄侧和雌侧结合固定在手腕上。将雄侧和雌侧的位置颠倒亦可，这里不再赘述。
压迫气囊2上还设置有鞘管标记(图中未示出)，鞘管标记用于对准桡动脉6上的穿刺部位。将压迫气囊2对准穿刺部位后，向压迫气囊2注入气体膨胀，对桡动脉6的穿刺部位进行压迫止血。
压迫气囊2通过注气管31连接注气端口3，注气端口3作为向压迫气囊2内注入气体的端口。注射器连接注气端口3可后向压迫气囊2内注入气体，注气端口3内设置有止回阀，当注射器连接注气端口3后，能够将止回阀打开，并进行注气；当注射器脱离注气端口3后，止回阀关闭从而防止气体漏出。
优选的，压迫气囊2的截面形状可以是圆形，注入气体后呈球体状；压迫气囊2的截面形状也可以是矩形状，注入气体后，呈矩形气囊状，当然也可以是其他形状。
优选的，压迫气囊2可以是透明的，也可以是半透明或有色透明。
进一步的，压迫气囊2还通过压力检测管41连接压力感受器4，压力感受器4用于检测压迫气囊2内气体产生的压力震荡波，该压力震荡波是由桡动脉6引起的。压力检测管41上还设置有控制装置5，压力感受器4与控制装置5一体成型；控制装置5内设置有控制模块 51，控制模块51与压力感受器4电连接，控制装置5的表面设置有显示模块52，控制模块51能够将压力震荡波后转化为正弦形的脉搏波，并通过显示模块52显示脉搏波或血压值。
如果压迫气囊2内的内压(气压)大于桡动脉6的收缩压，桡动脉6受压关闭(即桡动脉6发生闭塞)，压迫气囊2内不产生压力震荡波，显示模块52上没有脉搏波；如果桡动脉6的收缩压大于压迫气囊2的内压，压迫气囊2内产生压力震荡波，即桡动脉6没有闭塞，有血液流动，显示模块52上的脉搏波的幅度出现；随着压迫气囊2的内压下降(压迫气囊放气)，脉搏波的幅度逐渐增大，当压迫气囊2的内压等于桡动脉的平均动脉压时，脉搏波的幅度达到最大；随着压迫气囊的内压逐渐下降(压迫气囊放气达到一定程度)，脉搏波的幅度逐渐降低，当压迫气囊2的内压小于桡动脉6的舒张压时，脉搏波消失。通过该方式能够及时了解桡动脉6在通过压迫器进行止血时，是否发生闭塞，以方便医护人员及时调整压迫气囊2的内压，避免压迫气囊2的内压过大，造成桡动脉6闭塞。
进一步的，控制装置5内还设置有报警模块53，控制模块51与报警模块53电连接，当桡动脉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迫气囊2进行减压。
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。
优选的，在本实施例中，注气端口3同时作为放气端口，可放出压迫气囊2内的气体。注射器连接注气端口3可抽取压迫气囊2内的气体进行减压。
作为本发明的第二个实施例，如图3所示，注气管31与压力检测管41连通，压力检测管41并未直接与压迫气囊2连通，而是间接通过注气管31连通压迫气囊2；其他部分则与上述第一个实施例相 同，这里不再赘述。
作为本发明的第三个实施例，在第一个实施例的基础上，如图4所示，压力感受器4还连接有放气管42，放气管42的末端设置有放气端口55，放气端口55与注气端口3的组成结构相同，这里不再赘述。放气端口55用于放出压迫气囊2内的气体，注射器连接放气端口55后，可抽取压迫气囊2内的气体进行减压。
作为本发明的第四个实施例，在第一个实施例的基础上，如图5所示，压力感受器4还连接有放气管42，放气管42上设置有放气模块56，放气模块56与控制模块51电连接；当压迫气囊2的内压过大造成桡动脉6闭塞时，控制模块51可控制放气模块56开启，对压迫气囊2进行自动减压。
优选的，放气模块56可以是电控气泵、电控气阀等。
作为本发明压迫器的第五个实施例，如图6和图7所示，在第一个实施例的基础上，相同的部分则不再赘述。压迫器还包括与第一固定带1并排设置的第二固定带7，第二固定带7上设置有柯氏音提取模块8，柯氏音提取模块8用于采集桡动脉6振动产生的柯氏音。柯氏音提取模块8设置在第二固定带7的下表面，用于与桡动脉6相接触。
柯氏音提取模块8通过第一信号线缆81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内还设置有扩音模块82，控制模块51通过扩音模块82播放柯氏音。控制模块51还通过显示模块52显示柯氏音波形。
若桡动脉6闭塞，柯氏音提取模块8无法提取柯氏音，表明压迫气囊2的内压过大，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，通过该方式也能够判断桡动脉6是否存在闭塞。
优选的，第二固定带7上表面的右侧边缘设置有魔术贴的雄侧， 第二固定带7下表面的左侧边缘设置有魔术贴的雌侧，将第二固定带7缠绕手腕后可以通过雄侧和雌侧结合固定在手腕上。
在本实施例中，综合柯氏音提取模块8提取柯氏音以及压力感受器4采集压迫气囊2内气体产生的压力震荡波来判断桡动脉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。
优选的，控制模块51与扩音模块82之间电连接有柯氏音开关83，柯氏音开关83设置在控制装置5的表面，通过按压柯氏音开关83能够开启或关闭柯氏音的播放。
优选的，在本实施例中，注气端口3可以同时作为放气端口，参照上述第一个实施例。

作为本发明的第六个实施例，在第一个实施例的基础上，相同的部分则不再赘述。如图8所示，还包括与第一固定带1并排设置的第二固定带7，第二固定带7上设置有光电容积脉搏波检测模块9，光电容积脉搏波检测模块9用于采集桡动脉6的脉搏信号。光电容积脉搏波检测模块9设置在第二固定带7的下表面，用于与桡动脉6相接触。
优选的，光电容积脉搏波检测模块9可以是柔性传感器，具有良好的柔韧性、延展性。
光电容积脉搏波检测模块9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9通过第二信号线缆91电连接控制装置5内的控制模块51，控制模块51通过显示模块52显示脉搏波。
优选的，第二固定带7上表面的右侧边缘设置有魔术贴的雄侧，第二固定带7下表面的左侧边缘设置有魔术贴的雌侧，反之亦可；将第二固定带7缠绕手腕后可以通过雄侧和雌侧结合固定在手腕上。
在本实施例中，综合光电容积脉搏波检测模块9获取桡动脉6的血流的变化以及压力感受器4采集压迫气囊2内气体产生的压力震荡波来判断桡动脉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。
作为本发明的第七个实施例，在第一个实施例的基础上，相同的部分则不再赘述。如图9所示，还包括与第一固定带1并排设置的第二固定带7，第二固定带7上设置有压电感受器10，压电感受器10用于采集桡动脉6的脉搏信号，压电感受器10设置在第二固定带7的下表面，用于与桡动脉6相接触。
