Description

脉搏压力传导结构、便携式血压检测模块和智能穿戴设备 技术领域
本发明涉及血压检测装置，具体涉及一种血压检测装置的脉搏压力传导结构。
 背景技术
动脉血压是临床实践中最重要和最常用的测量参数，而且血压还是各种重要心血管疾病的风险评分中的组成部分，因此对血压的测量在医学上有着重要的意义。
目前的无创电子血压计大多使用示波法，个别使用听诊法。无论示波法的血压计还是听诊法的血压计都是袖带式血压计。其中，袖带包括布袋及气囊，通常要求气囊的长度大致为肢体的0.8倍，气囊的宽度为肢体的0.4倍。血压测量时，将袖带缠绕于肢体，压住肢体动脉血管。通过加压袖带内的气囊，阻止动脉血管血流，检测气囊内气压变化或检测柯氏音及气囊内气压，从而检测血压。
这种袖带式血压计的问题在于，使用时需要使这种袖带（气囊）缠绕于肢体上，使用部位有限制，而且使用麻烦。同时，由于占用了手腕或手臂整周，使得需同时检测血压以外的生命体征参数（如通过光电法检测心率）的设备难以实现。

实施例一
本实施例提供一种便携式血压检测模块，该便携式血压检测模块能够单独使用，也可附加到其他穿戴设备上使用，用于通过示波法或听诊法实现血压的检测。
在一种实施例中，该便携式血压检测模块包括壳体、脉搏压力传导部件、充放气结构、检测单元以及血压计算单元。
该壳体具有安装腔，该脉搏压力传导部件安装在壳体上，与壳体形成一种脉搏压力传导结构。需要指出的是，该脉搏压力传导结构不仅可运用到本实施例这种便携式血压检测模块上，也可以运用到其他形式的电子血压计上，例如台式电子血压计、腕表式电子血压计等。
具体地，在该脉搏压力传导结构中，脉搏压力传导部件并与壳体围合形成用于充气的型腔。脉搏压力传导部件至少一部分从壳体中露出，使得脉搏压力传导部件能够在充气时直接或间接作用到待检测对象的检测部位。
该脉搏压力传导结构代替了传统的气囊结构，通常来说脉搏压力传导部件至少部分具有一定的扩展性或弹性，例如在一种实施例中，该脉搏压力传导部件包括弹性材料制成的弹性部和/或柔性材料制成的柔性部。使用时向型腔内充气，促使脉搏压力传导部件扩展，使得脉搏压力传导部件至少一部分外凸于壳体并直接或间接贴附检测部位，从而完成脉搏压力的传导。
该充放气结构与型腔连通，用于对型腔进行充放气操作。检测单元则用于检测型腔的脉搏压力信号并传递给血压计算单元，血压计算单元根据检测的脉搏压力信号计算出血压检测结果。
其中，该脉搏压力传导部件可直接贴附到检测部位，也可以隔着保护套或者外套等其他部件间接贴附到检测部位上。
该充放气结构、检测单元和血压计算单元安装在安装腔内，脉搏压力传导部件可以部分或全部安装在安装腔内，只在充气时有一部分凸出壳体贴附待测部位。或者脉搏压力传导部件直接贴附在壳体外壁，整个脉搏压力传导部件露在壳体外，脉搏压力传导部件的体积基本与壳体一致或略大于壳体，无需像传统的气囊一样围绕整个手腕或手臂。由此使得整个便携式血压检测模块体积可以设计的非常小。
请参考图1，在一种实施例中，该血压计算单元103可以是单片机或其他具有逻辑运算功能的装置。充放气结构包括慢速泄气阀104、快速排气阀105和气泵108。该气泵108、慢速泄气阀104和快速排气阀105均内置于壳体的安装腔内。
在本实施例中采用示波法实现血压的测量。具体地，检测单元采用气压传感器106，其内置于安装腔。在其他实施例中，检测单元也可以采用声音传感器，通过听诊法来检测血压。
该脉搏压力传导部件包括弹性膜102,该弹性膜102设置于壳体101下方，与壳体101外壁形成型腔。该型腔与气泵108、快速排气阀105及气压传感器106连通构成气路。
请参考图1-3，在一种实施例中，以腕部桡骨动脉检测为例，其中RA表示桡骨动脉，W表示手腕，100代表便携式血压检测模块。
使用时，壳体101设置于桡骨动脉血管处，便携式血压检测模块100被贴附在桡骨动脉血管RA上。开始检测时，气泵108给型腔加压，使弹性膜102压迫动脉血管RA，阻止血液流动。此时，慢速泄气阀104缓慢地泄放型腔中的压缩气体，血管压力的变化叠加于型腔内部气压，气压传感器106检测型腔压力的变化。血压计算单元103根据气压传感器106检测的信号，计算出血压值。此后，快速排气阀105将型腔中的气体快速排放，释放动脉血管。
另外，便携式血压检测模块100还可以包括电源107，用于给用电部件供电。或者，还可以是具有电池仓，用于安装干电池等可拆卸式电池。此外，还可以具有电源连接线，用于与外接电源连接。
便携式血压检测模块100还可以通信单元，该通信单元与血压计算单元103连接，用于将便携式血压检测模块100与其他装置建立通信连接。通信连接可以是无线或者有线通信，较好的是选择无线方式，这样便于便携式血压检测模块100的使用。
请继续参考图1，在一种实施例中，该通信单元采用的是无线传输单元110，其可与其他终端，例如遥控器、手机、智能手表等，建立无线通信。从而由外接终端来控制便携式血压检测模块100的开始、暂停和结束等操作，同时也可以由外接终端来显示便携式血压检测模块100的测量结果。
例如，便携式血压检测模块100在接收到外接终端的开始指令后，即开始检测工作。检测工作完成后，将检测结果反映到外接终端上。
另一方面，在一种实施例中，便携式血压检测模块100还包括显示单元和/或声音提示单元，该显示单元和/或声音提示单元与血压计算单元103连接，用于显示和/或提示检测结果。
显示单元可以是显示屏、触控屏等屏类显示装置，也可能是指示灯（不同颜色的指示灯代表不同检测结果）等结构。
声音提示单元则可以是各种能够进行声音提示的装置，例如语音播报等。
进一步地，该便携式血压检测模块100可以独立的运用于各个能够检测到动脉脉搏的部位，如手腕、手臂、颈部动脉、心脏等部位。使用时，可通过自带的佩戴结构固定在这些部位，该佩戴结构与壳体101固定连接（直接或间接固定连接），用于将便携式血压检测模块100佩戴在待测对象的动脉血管处。例如，在某些实施例中，佩戴结构包括带状结构、环状结构、吸合结构、粘合结构中的至少一种。请参考图4，在一种实施例中，佩戴结构可以为腕带109。
带状结构包括如表带或者其他带状物体一样的结构，其通过扣合、绑系、粘合等方式形成环状结构，使得便携式血压检测模块100能够被佩戴在手腕、手表、颈部等部位。
环套结构包括具有弹性的环套或环带结构。吸合结构包括吸盘等通过吸合作用实现安装的结构。粘合结构包括医用胶布等用于粘合固定的结构。
此外，还可以在便携式血压检测模块100上不设置佩戴结构，而直接通过其他外部固定手段实现便携式血压检测模块100的安装，例如采用医疗中常用的医用胶布把便携式血压检测模块100贴在待测部位。
另一方面，便携式血压检测模块100除了独立使用外，还可以附加到其他穿戴设备上使用。
在其他实施例中，便携式血压检测模块100包括安装结构，该安装结构与壳体101固定连接，用于将便携式血压检测模块100安装到其他装置上。通常是以可拆地方式固定在其他穿戴设备上。当然，在某些实施例中，也可是不可拆卸式的固定。
在一些实施例中，安装结构包括粘接结构、卡接结构、螺接结构、磁性吸附结构中的至少一种。
粘接结构包括魔术贴等一系列可以实现粘接安装的结构。卡接结构包括利用卡扣配合所实现固定的结构。螺接结构包括通过螺钉固定方式实现安装的结构以及将便携式血压检测模块100自身螺纹连接到穿戴设备上的结构。磁性吸附结构包括利用磁性吸附力所实现的固定结构。
请参考图5，在一种实施例中，该便携式血压检测模块100安装在一种手表200上，该手表200包括表头210和表带220，该便携式血压检测模块100装设在表带220的内侧，使得戴上表带220后，便携式血压检测模块100可以贴附于桡骨动脉，进而测量脉搏压力。
该手表200可以是用于显示时间的普通手表200，也可以是兼具其他功能的智能手表200。当手表200为智能手表200时，该智能手表200可以与便携式血压检测模块100的通信单元建立无线和/或有线通信连接，进而用来控制便携式血压检测模块100和/或显示便携式血压检测模块100检测结果。
另一方面，为了形成所要的型腔，在某些实施例中，壳体101与脉搏压力传导部件中至少其一具有凹腔，该壳体101与脉搏压力传导部件将凹腔封闭形成上述型腔。
当然，在其他实施例中，当脉搏压力传导部件本身具有弹性时，也可以不形成凹腔，而是在充气时依靠材料本身的变形从而产生需要的型腔。
进一步地，在某些实施例中，脉搏压力传导部件安装在壳体101内，且脉搏压力传导部件的一部分从壳体101内伸出到壳体101外。这种情况下脉搏压力传导部件只有需要与待测部位贴附的部分从壳体101中伸出，能进一步将便携式血压检测模块100设计的更小，更便于携带和使用。
通常来说，脉搏压力传导部件露出壳体101的部分可以采用弹性膜102或柔性膜制成，这可以利用弹性膜102的弹性特性，使其在膨胀变形时能够伸出到壳体101外，而泄气时会收回到壳体101内或者收回到靠近壳体101的位置，使得便携式血压检测模块100体积更小。
请再次参考图1和2，通常手腕的桡骨动脉血管的内径大致为2.3+/-0.4mm，考虑到穿戴时引起的位置误差，可以设计一种脉搏压力传导部件，比如大致10mm长、宽度8mm的弹性膜，其完全可以覆盖住桡骨动脉血管。通过给型腔加压（或加压后减压），使桡骨动脉血管内的压力变化叠加于型腔的内压。检测叠加了桡骨动脉血管内压的型腔压力的变化，即可测量出桡骨动脉血管的血压。
这种血压检测模块，无需缠绕肢体、仅覆盖肢体的局部动脉血管、不形成佩带负担，比如，如图5所示，将这种装置设置于表带与手腕桡骨动脉之间进行血压检测。这种血压检测模块的大小甚至可以达到20mm*15mm*8mm或以下，目前手表的表带宽度大致20mm，宽一点的话大致30mm左右。由于没有占用手腕太多空间，可以配合通过光电法检测心率的手表一起使用
