本申请的说明书和权利要求书及上述附图中的术语“第一”、“第二”、“第三”、“第四”等(如果存在)是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本申请的实施例，例如能够以除了在这里图示或描述的那些以外的顺序实施。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含，例如，包含了一系列步骤或单元的过程、方法、***、产品或设备不必限于清楚地列出的那些步骤或单元，而是可包括没有清楚地列出的或对于这些过程、方法、产品或设备固有的其它步骤或单元。
本申请首先提出一种血压脉象检测***，如图1及图2所示，本实施例血压脉象检测***101包括血压脉象检测装置102及与血压脉象检测装置102建立连接的终端103，其中，如图2所示，血压检测装置102包括主机11和袖带12，袖带12包括气体通道121和气囊袋122，气体通道121和气囊袋122的气路接口连接，主机11包括控制器111、压力传感器112及气泵113，控制器111与气泵113及压力传感器112耦接，气体通道121与气泵113连接，控制器111用于控制气泵113通过气体通道121对气囊袋122进行充气，控制器111用于控制压力传感器112检测气体通道121的压力，并控制器111控制压力传感器112检测人体的多个脉搏波，并将多个脉搏波发送给与终端103。
气囊袋122用于容纳气体，例如空气。其中，气体通道121可以为软胶管；在其他实施例中，气体通道121可以为其他材质管道。
终端103可以包括诸如手机、平板电脑、笔记本电脑、掌上电脑、个人数字助理及可穿戴设备等，服务器104是分布在网络或云端的智能计算机***。
本申请进一步提出一种血压脉象检测方法，用于上述血压脉象检测***，如图3所示，本实施例的检测方法包括以下步骤：
步骤S301：控制器111控制气泵113对袖带12的气囊袋122进行充气。
控制器111在接收到检测指令时通过气泵驱动电路115控制气泵113工作，此时泄气阀114关闭，此时气泵113通过气体通道121对气囊袋122进行充气。
步骤S302：控制器111控制压力传感器112检测气体通道121的压力，并将压力与预设的第一压力阈值进行比较。
控制器111控制压力传感器112检测气体通道121的气体的压力，并将气体的压力发送给控制器111，控制器111将压力与预设的第一压力阈值进行比较。
步骤S303：若压力等于第一压力阈值时，控制器111控制气泵113停止充气。
在控制器111判断到气体的压力超过第一压力阈值时，控制器111通过气泵驱动电路115控制气泵113停止工作。
步骤S304：控制器111控制压力传感器检测人体的多个第一脉搏波，并将多个第一脉搏波发送给终端103。
具体获得脉搏波形的方法包括：控制器111获得气体介质的压力与时间的波形；控制器111提取不同脉搏周期内的气体介质的压力的极小值点，将两个极小值点间的波形减去两个极小值点连接的直线，以得到脉搏波形。
终端103进一步对第一脉搏波进行处理及显示处理结果。
由于气泵113加压过程对气囊袋122的压力叠加了高频的波动，对脉搏波波形细节的影响很大，在压力等于第一压力阈值时，控制器控制气泵停止充气，使压力传感器在恒压下检测人体的多个第一脉搏波，能够避免气泵充气过程或者泄气阀放气过程对袖带气囊的产生压力波动，因此，能够减少对第一脉搏波的干扰，能够提高第一脉搏波的准确度。
本申请进一步提出另一实施例的血压脉象检测方法，用于上述血压脉象检测***，如图4所示，本实施例的检测方法包括以下步骤：
步骤S401：控制器111控制气泵113对袖带12的气囊袋122进行充气。
步骤S401与上述步骤S301相同，这里不赘述。
步骤S402：控制器111控制压力传感器112检测气囊袋122的压力，以获取人体的第二脉搏波。
步骤S403：控制器111提取每个脉搏周期对应的第二脉搏波的极大值。
步骤S404：控制器11根据第二脉搏波的多个极大值中的最大值计算收缩压和舒张压作为人体的血压信息。
其中，收缩压为所述最大值与第一系数的乘积，舒张压为所述最大值与第二系数的乘积。
步骤S405：控制器111控制压力传感器112检测气体通道121的压力，并将压力与预设的第一压力阈值进行比较。
步骤S406：若压力等于第一压力阈值时，控制器111控制气泵113停止充气。
步骤S407：控制器111控制压力传感器检测人体的多个第一脉搏波，并将多个第一脉搏波发送给终端103。
步骤S405及S407与上述步骤S302及S304相同，这里不赘述。
终端103进一步对脉搏波进行处理及显示处理结果。
区别于现有技术，本实施例进一步在加压阶段获取人体的第二脉搏波，以根据第二脉搏波获取血压数据，以同时实现血压数据及脉象信息的检测。
本申请进一步提出另一实施例的血压脉象检测***，如图5所示，本实施例血压脉象检测***在上述实施例的基础上进一步包括服务器104，终端103分别与血压脉象检测装置102及服务器104建立通信连接。本实施例的终端103可以与血压脉象检测装置102建立有连接或者无线连接，终端103可以与服务器104建立无线连接。
本申请进一步提出又一实施例的血压脉象检测方法，如图6所示，本实施力的方法包括以下步骤：
步骤S601：控制器111控制气泵113对袖带12的气囊袋122进行充气。
步骤S602：控制器111控制压力传感器112检测气体通道121的压力，并将压力与预设的第一压力阈值进行比较。
步骤S603：若压力等于第一压力阈值时，控制器111控制气泵113停止充气。
步骤S604：控制器111控制压力传感器检测人体的多个第一脉搏波，并将多个第一脉搏波发送给终端103。
步骤S601-S604与上述步骤S301-S304相同，这里不赘述。
步骤S605：终端103将多个第一脉搏波转发给服务器104。
步骤S606：服务器104对多个第一脉搏波进行处理，以根据分析结果获取健康信息。
本实施例的服务器104对终端103转发的第一脉搏波进行分析，以获取人 体的健康信息，终端103可以显示服务器104回传的健康信息及血压脉象检测装置102检测的第一脉搏波。
因人体健康信息往往需要丰富的经验数据及推理规则得出，而服务器104可以获取丰富的血压脉象检测数据，且具有较强的数据处理能力，因此本实施例通过服务器104对第一脉搏波进行分析，以获取人体的健康信息，能够提高第一脉搏波检测及数据处理的准确度。且本实施例的终端103显示健康信息及第一脉搏波信息，能使用户及时了解自身的健康状况，减少疾病风险。
其中，脉搏波是由心脏的动推血液沿管运行而产生的，它是一种周期性压力波。人体的脉搏波蕴含着丰富的生理信息，如血压、心率及心血管信息等。通过对脉搏波形的分析，能够获取心血管健康信息，以减少心血管疾病的发生。
可选地，为提高健康信息的准确度，服务器104在从终端103获取多个第一脉搏波之后，需要对多个第一脉搏波进行滤波处理，以剔除干扰噪声。
具体地，本实施例可以通过如图7所述的方法实现滤波，本实施例包括以下步骤：
步骤S701：服务器104获取第一脉搏波的幅值或周期。
具体地，服务器104可以获取第一脉搏波的特征点的幅值，该特征点可以包括第一脉搏波的反射波点、波峰点、波谷点或者其它极值点或拐点等。
步骤S702：服务器104判断幅值是否在预设幅值范围内。
步骤S703：若幅值在预设幅值范围内，则服务器104判断第一脉搏波为第三脉搏波，并滤除除第三脉搏波之外的脉搏波。
服务器104在从终端103获取多个脉搏波之后，需要对多个第一脉搏波进行滤波处理，以剔除干扰噪声，能够提高健康信息的准确度。
在另一实施例中，服务器还可以获取第一脉搏波的周期，并将周期不在预设周期内的脉搏波滤除，以获取第三脉搏波，即以周期作为滤波条件。当然，在其它实施例中，还可以将第一脉搏波的幅值及周期同时作为滤波条件。
可选地，不同的脉象表征了人体不同的健康状况，为提高健康信息的准确度，本实施例的服务器104可以通过步骤S704-S706对第三脉搏波进行脉象(波形)识别。本实施例的方法包括以下步骤：
步骤S704：服务器104将第三脉搏波与预设波形进行匹配。
不同的人体，或者同一人体处于不同的健康状态时，产生的脉搏波不同，即脉象不同。中医常见的脉象有多种，如滑脉、促脉、弦脉、平脉、浮脉、沉 脉、迟脉、数脉、虚脉等等，每种脉象的波形存在差异，如图2所示，滑脉、促脉、弦脉及平脉的波形均不同。
不同的脉象表征了人体不同的健康状况，为提高健康信息的准确度，本实施例的服务器104进一步对第三脉搏波进行脉象(波形)识别。
具体地，本实施例的服务器104存储有预设波形，该预设波形至少包括滑脉波形、促脉波形、弦脉波形或平脉波形等。例如，服务器104判断终端103转发的第三脉搏波与预设的滑脉波形匹配，则判断该第三脉搏波为滑脉；服务器104进一步可以将第三脉搏波或第一预设波形及健康信息“滑脉”回传给终端104。
本实施例可以通过如图8所述的方法实现步骤S704，本实施例的方法包括以下步骤：
步骤S801：服务器104分别获取第三脉博波的第一特征信息及预设波形的第二特征信息。
本实施例的特征信息可以包括第三脉博波的波形周期及波形驻点(包括极值点及拐点)信息。其中，波形驻点信息包括波形驻点的数量及相邻波形驻点之间的时间间隔等信息。
步骤S802：若第一特征信息与第二特征信息之间的差值小于预设差值，则服务器判断第三脉博波与预设波形匹配。
本实施例可以通过脉搏波的波形周期及波形驻点信息识别脉博波的脉象(波形)。当然，在其它实施例中，还可以根据脉搏波的其它特征信息识别脉博波的脉象(波形)。
具体地，本实施例的特征信息可以包括第三脉博波的波形周期及波形驻点(包括极值点及拐点)信息。其中，波形驻点信息包括波形驻点的数量及相邻波形驻点之间的时间间隔等信息。如图9所示，促脉的波形周期与其它脉象的波形周期相差较大，若服务器104判断第三脉博波的波形周期与预设的促脉波形的波形周期的差值小于预设差值，则可以判断第三脉博波为促脉；若服务器104判断该差值大于预设差值，则进一步判断第三脉博波的波形极值点的数量是否为2(预设的滑脉的波形极值点的数量为2)，且判断第二波形驻点的幅值是否较大并且是否比第一波形驻点位置低，若是，则可以判断第三脉博波为滑脉；若服务器104判断第三脉博波的波形极值点的数量是等于3，则可以进一步判断第三脉博波的第一波形驻点与第二波形驻点之间的间隔时间是否小于预设时间 (预设的弦脉的第一波形驻点与第二波形驻点之间的时间间隔)，若是，则可以判断第三脉博波为弦脉，等等。
本实施例可以通过脉搏波的波形周期及波形驻点信息识别脉博波的脉象(波形)。当然，在其它实施例中，还可以根据脉搏波的其它特征信息识别脉博波的脉象(波形)。
当然，服务器在进行脉象识别前可以先对获取的波形驻点进行过滤，以减少噪声干扰。
步骤S705：服务器104获取与第三脉博波对应的预设波形为第一预设波形。
步骤S706：服务器104根据第一预设波形得到健康信息。
当然，在另一实施例中，服务器还可以获取脉搏波的周期，并将周期不在预设周期内的脉搏波滤除，以获取第三脉搏波，即以周期作为滤波条件。当然，在其它实施例中，还可以将脉搏波的幅值及周期同时作为滤波条件。
脉诊是中医诊断学四诊之一，是一种独特的诊断方法。它主要是利用手指的感觉来分析脉搏的“位、数、形、势”等特征，借以判断脏腑的功能状态，从而实现无创诊断的目的，对疾病的诊断和治疗有着积极的意义。
现有的脉象仪虽然可以做到意会切脉过程，将脉搏波图形化并显示，使用户通过脉搏波直观的认识脉象，但从脉象获取健康信息，需要丰富的临床经验，因此非医护人员或非专业医护人员很难从脉象波形中准确的得到健康信息。
为解决上述问题，本实施例的服务器104进一步对第三脉博波进行分析，以从第三脉博波获取更具体的人体健康信息，本实施例的健康信息除了包括脉象信息，还包括血压、脉搏力度、脉率、脉律和反映动脉弹性的反射波增强指数(AI)等信息。
具体地，服务器104获取整个测量过程中脉波幅值最大的几个脉搏波，如3个，并根据波峰点的幅值取均值获取人体的脉搏力度。均值的幅值越大，脉搏力度越大，脉搏力度的大小表征了人体体质的强弱；服务器104还可以从第一脉搏波获取脉率、脉律和AI值等。
服务器104将上述获取的健康信息回传给终端102，终端102显示健康信息，如图10及图11所示。
进一步地，服务器104存储有预设范围，判断上述健康信息是否在预设范 围内；若是，则控制终端103上的健康信息显示状态为正常；若否，则终端显示103上的健康信息显示状态为异常。
服务器104还可将第三脉搏波或者与第三脉搏波对应的脉象波形及第三脉搏波的类型、血压数据等回传给终端103，终端103显示脉象波形及类型、血压数据。
可选地，本实施例的服务器104进一步根据反射波点及波峰点获取人体的血管弹性的健康信息，例如，若服务器104判断反射波点在波峰点的右侧(如图10所示)，则获取的健康信息为血管弹性较好，若服务器104判断反射波点在波峰点的左侧(如图11所示)，则获取的健康信息血管弹性较差；服务器104还可以根据心率数据获取心率过缓或者过速、心率不齐及等健康信息；服务器104还可以根据AI值获取动脉健康信息，等等。终端103也可显示这些健康信息。
步骤S607：服务器104将健康信息回传给终端102。
步骤S608：终端102显示健康信息。
服务器104还可将第三脉搏波或者与第三脉搏波对应的脉象波形及第三脉搏波的类型、血压数据等回传给终端103，终端103显示脉象波形及类型、血压数据。
本实施例的通过服务器104对第一脉博波进行分析，以获取人体的健康信息，能够提高血压脉象检测及数据处理的准确度；且本实施例的终端103能够显示详细健康信息，而不只是脉搏波，使得非医护人员也能通过该健康信息清楚了解自身的健康状态。
可选地，继续参阅图2，主机11设置有一接口110，该接口110用于与终端103建立连接，主机11通过袖带12检测人体动脉的血压脉象检测数据，并通过接口110将血压脉象检测数据发送给终端103，即血压检测装置102可以通过接口110与终端103进行数据通信，实现联网功能，提高用户的使用体验；且终端103通过接口110向血压检测装置102供电，因此血压检测装置102无需设置内置电源，减小血压检测装置10的体积和重量，实现小型化，方便携带，能够满足用户随时测量的需求。
其中，终端102具有USB OTG(USB On-The-Go)功能，该数据线21可为OTG数据线。在终端20通过数据线21与血压检测装置102连接时，终端20作为主设备，血压检测装置10为从设备。
可选地，本实施例的主机11进一步可以包括泄气阀114、气泵驱动电路115、泄气阀驱动电路116、数模转换电路117以及转换器118；压力传感器112、气泵113和泄气阀114分别与控制器111耦接，控制器111用于控制气泵113对气囊袋122进行充气，控制泄气阀114对气囊袋122进行放气，控制压力传感器112对气体通道121中气体的压力进行检测。
气体通道121可以延伸到主机11，气体通道121可以分别与压力传感器112、气泵113和泄气阀114连接。气泵驱动电路115连接在气泵113和控制器111之间，用于驱动气泵113，即控制器111通过气泵驱动电路115驱动气泵113，以将气体充入气囊袋122。泄气阀驱动电路116连接在泄气阀114和控制器111之间，用于驱动泄气阀114，即控制器111通过泄气阀驱动电路116驱动泄气阀114，以将气囊袋122的气体进行放气。
其中，主机11设置有袖带接口，袖带12的气体通道121与袖带接口可拆卸连接，气体通道100通过袖带接口分别与压力传感器112、气泵113和泄气阀114连接。
数模转换电路117连接在压力传感器112和控制器111之间；在压力传感器112检测到气体通道121中气体的压力时，压力传感器112用于将气体的压力转化为模拟信号，并将模拟信号传输至数模转换电路117；数模转换电路117将模拟信号转化为数字信号，并将数字信号发送给控制器111。
接口110可以包括电源端，电源端分别与气泵驱动电路115和泄气阀驱动电路116连接，用于向气泵驱动电路115和泄气阀驱动电路116提供第一电压V1。转换器118的输入端与电源端连接，用于将第一电压V1转换为第二电压V2；转换器118的输出端分别与控制器111、压力传感器112和数模转换电路117连接，用于向控制器111、压力传感器112和数模转换电路117提供第二电压V2，其中第二电压V2小于第一电压V1。
接口110进一步包括数据传输端，终端103通过数据传输端向控制器111发送检测指令，血压脉象检测装置102根据检测指令检测血压脉象检测数据。
在其他实施例中，气囊袋可以包括预留的气体。控制器通过压力传感器对预留的气体进行压力检测，并根据压力检测结果判断是否启动血压脉象检测；若是，则血压脉象检测装置进行血压脉象检测。通过这种方式，能够实现自动启动血压脉象检测，提高用户的体验效果。
在其他实施例中，控制器进一步获取压力检测结果与第二压力阈值的压力 变化幅度，在控制器判断到压力变化幅度大于预设的变化幅度阈值时，控制器启动血压脉象检测。在控制器判断到压力变化幅度小于预设的变化幅度阈值时，控制器控制血压脉象检测装置进入休眠状态，以节省功耗。
在其他实施例中，在血压脉象检测装置的加压阶段时，血压脉象检测装置采用闭环控制调节气体的充气速度，具体地控制器控制气泵对气囊袋进行充气，控制器通过压力传感器采集气体的压力为第一压力，控制器前一次通过压力传感器采集到的压力为第二压力；控制器根据第一压力和第二压力得到袖带的静压力。
控制器进一步根据静压力获取气囊袋中气体的加压速率，并将加压速率与恒定速率进行比较；在控制器判断到加压速率小于恒定速率时，控制器控制气泵的转速增大；在控制器判断到加速度速率大于恒定速率时，则控制器控制气泵的转速减小，以使得加压速率为恒定速率。因此，控制器控制气泵对气囊袋进行充气，进而控制气泵通过气体通道以恒定速度进行充气，以保证控制器获得脉搏波的准确性。
本申请进一步提出一种血压脉象检测装置，本实施的血压脉象检测装置为上述实施例中的血压脉象检测装置102，其具体结构及工作原理这里不赘述。
