上述采集多参数健康指标的手环,在测量印制板上共设置了一个光源和多个光敏传感器,经光源发射后从手腕下面的皮肤反射回的光信号被多个光敏传感器所接收,将多个光敏传感器所接收到的光信号进行叠加后作为微处理器的原始输入值。
与现有技术相比,本发明的有益效果是:本发明提出的能采集多参数健康指标的手环,将包含微处理器、存储器和模拟信号处理芯片的主控系统设置在了主体内,其主体位于手环的上部,在戴带后即位于人体手背侧的手腕上面的外关穴附近;将装配有体表温度传感器、光敏传感器和光源等测量部件的测量印制板设置在了腕带上,测量印制板位于手环的下部,在戴带后即位于人体掌心侧的手腕下面的内关穴附近;测量印制板和主控系统通过设置在腕带上的柔性连接线缆进行电连接,由于人体手腕下面的血管丰富,脉博明显,此处反映的健康信息较为丰富,在此处采集人体信息,与现有技术在手腕上面采集信息相比,在手腕下面采集健康参数能大大提升测取数据的准确度。
在主体内设置时钟部件的有益效果是可以使该手环兼具手表的功能,设置显示屏的有益效果是能将测得的数据以可读取的方式进行直观显示,设置电源和充电接口的有益效果是为各电子元器件提供电能;在主控系统中设置微处理器的有益效果是通过微处理器进行各相关运算和转换,以将电子元器件测得的电信号准确的转换为人们可读取和识别的健康指标值,设置存储器的有益效果是在存储器内固设运算软件和传输协议,以便为微处理器的运算提供规则和方法,同时还在存储器内保存每次的测量值,以便用户查询、对比和追溯。在主控系统中设置模拟信号处理芯片的有益效果是为了对传感器传回的电信号进行信号放大、信号滤波和信号模数变换,识别和放大信号中的有效信息,去除信号中的杂质和无效信息,再将净化过滤后的有效信息发送给微处理器,以提高信息的准确性进而提升测量值的准确度;在主控系统中设置红外温度传感器的有益效果是通过红外温度传感器可以以不接触的方式采集和测得人体的体温,一般是在3-5厘米的距离外测量,通常用于测量人体的额头温度,其测量方便,举手即可完成,而且测量时间短。在主控系统中设置蓝牙传输装置的有益效果是可以实现主控系统与手机或平板电脑等手持移动终端进行双向数据传输,将主控系统和手持移动终端匹配相同的传输协议,手持移动终端通过蓝牙传输装置 向主控系统发送控制指令,主控系统也通过蓝牙传输装置向手持移动终端发送数据信息,并通过手持移动终端的APP系统而显示在手持移动终端的界面上。
在腕带上设置柔性连接线缆是为了方便测量印制板和主体之间的连接,柔性连接线缆可随腕带而任意弯折,其连接可靠且寿命长,通常的柔性连接线缆包括柔性印制板或扁平电缆。在腕带上布设测量印制板并在测量印制板上设置体表温度传感器是为了采集人体的体表温度,如将手环戴在手腕上,体表温度传感器的测量探头透过腕带内侧的采集窗直接与手腕下面的皮肤接触,或者在腕带内侧安装体表温度传感器的位置设置金属导热材质,并通过该金属导热材质而让温度传感器的测量探头与手腕下面的皮肤间接接触,采集手腕下面皮肤的温度;如将其腕带夹在腋下则可采集人体腋窝部位的温度,其使用方便,采集快捷,通常只需几秒钟即可测得所接触部位的体表温度值。在腕带上设置光源和光敏传感器是利用光反射的原理来测定心率和血氧饱和度,本发明的光源采用发射红光和红外光的双色LED光源,其向手腕下面的皮肤发射红色普通可见光和红外不可见光,光敏传感器接收皮肤反射回的可见光和不可见信号,并将该光信号转变为电信号,经过模拟信号处理芯片将电信号中的杂质过滤掉以后再发送给微处理器,微处理器按照存储器中固设的算法经过计算后即可将得到心率和血氧饱和度的具体值。
本发明在主体上对应红外温度传感器的位置开设了红外线的接收窗口,其有益效果是透过该窗口发送和接收反射回的红外线,以测定人体指定部位的红外温度。
设置一个光源和多个光敏传感器,将多个光敏传感器所接收到的光信号进行叠加后作为微处理器的原始输入值。是为了对反射回来的光进行更丰富的接收,通常情况下,一个光敏传感器所能接受的反射光较为有限,根据其值计算得出的参数往往不够准确,现有技术多是采用多个光源和一个光敏传感器来修正光敏传感器对反射光的接收值,但光源的体积较大,且能耗较多,而且这种方式的准确度也欠佳。
在主体中设置计步用重力加速传感器是为了增加本发明的功能,使其能够在用户散步或跑步的过程中记录其行经的步数,并根据其步长计算得出所行经的距离及体内热量消耗。
在主体中设置了报警装置,当测得值与存储器内预设的标准值相比,已超出健康指标参数的范围时,报警装置便发出警报,提醒用户注意健康并采取相应的措施。
在主体的主印制板上设置充电接口,是当采用充电电池作为电源的时候,方便通过该充电接口对壳体内的电源进行充电。
在腕带上设置了张紧装置,其有益效果是根据不同用户的手腕粗细可以调整腕带的长度以及腕带对手腕部位的压紧力,为了使其测量更加准确,需要在带上手环后,使腕带,尤其是腕带处的测量印制板对手腕部位有一定的接触压力,通过该张紧装置而能将其接触压 力调至合适的范围内。

具体实施方案
如图1至图3所示,本发明的第一种具体实施方式是,一种能采集多参数健康指标的手环,包括主体1和腕带2,其主体1又包括壳体11和设置在壳体11内的显示屏12、电源13、时钟部件17和主控系统,主控系统包括主印制板141和设置在主印制板141上的微处理器142、存储器143、模拟信号处理芯片144和蓝牙传输装置145,在主印制板141上还设置了红外温度传感器15、计步用重力加速度传感器16、报警装置18,另外在主体1上还为电源13设置了充电接口(图中未示出),以方便通过该充电接口对壳体11内的电源13进行充电,当然,如果电源13采用一次性钮扣电池时,便不需该充电接口,电能耗尽只需更换电池即可。其主印制板141上设置的各元器件均与微处理器142电连接,在存储器143内固设了心率、血氧饱和度运算软件、红外体温运算软件、步行距离及热量消耗运算软件、以及与手持移动终端之间的传输协议,手持移动终端采用智能手机或平板电脑,主控系统中的微处理器142和存储器143通过蓝牙传输装置145按照共同的协议与手持移动终端进行双向数据传输,手持移动终端通过蓝牙传输装置145向主控系统发送控制指令,如可使用手机通过蓝牙传输装置145向手环主体1发送每半小时定时采集一次人体健康数据的指令,主控系统也通过蓝牙传输装置145向手持移动终端发送数据信息,并通过手持移动终端的APP系统而显示在手持移动终端的界面上。
红外温度传感器15设置在主体1内的显示屏12的下方,并在主体1上对应红外温度传感器15的位置开设了红外线的接收窗口A,以透过该窗口A发送和接收反射回的红外线,以测定人体指定部位的红外温度,如通过红外温度传感器15以不接触的方式采集和测量人体的额头温度,在使用本实施方式的手环时,在距被测部位3-5厘米的距离处停留2至5秒钟,即可测得被测部位的准确温度,其测量方便,举手即可完成。
在腕带2上设置了柔性连接线缆21、柔性连接线缆21可随腕带21而任意弯折,在本实施方式中,柔性连接线缆21采用了柔性电路板,当然其也可以采用扁平电缆代替。在腕带2上还设置了测量印制板22,在测量印制板22上还设置了体表温度传感器23、光敏传感器24和光源25,在本实施方式中,其光源25采用发射红光和红外光双色LED光源,并均设置在腕带2的内侧,同时在其腕带2内侧的相应位置开设了采集窗B,光源25通过采集窗B向手腕下面的皮肤发送光信号,光敏传感器24也通过采集窗B接收手腕下面的皮肤反射回的光信号,本实施方式的采集窗B采用透光玻璃构成。在本实施方式中,在测量印制板22上共设置了一个光源25和两个光敏传感器24,当然如果只设置一个光敏传感器24也可实现数据采集和测量功能,但其误差值较大。
本实施方式还在腕带内侧安装体表温度传感器23的位置设置有金属导热材质C,通过金属导热材质C而让温度传感器23的测量探头与手腕下面的皮肤间接接触,以采集手腕下面皮肤的温度,当然体表温度传感器23的测量探头也可以直接与手腕下面的皮肤接触,但这样不利于保护探头,也易引起皮肤过敏。如果将腕带2设置有温度传感器23的部位夹在腋下则可采集人体腋窝部位的温度,其使用方便,采集快捷,通常只需5至10秒钟即可测得所接触部位的体表温度值。
测量印制板22位于手环的下部,在戴带后即位于人体掌心侧的手腕下面的内关穴F附近;主体1位于手环的上部,在戴带后即位于人体手背侧的手腕上面的外关穴E附近,测量印制板22上的电子元器件通过腕带上的柔性连接线缆21从主体1获取电能和指令,并将测得的数据通过柔性连接线缆21传输给主控系统,光源25向手腕下面的皮肤发射红色普通可见光和红外不可见光,其手腕下面的皮肤反射回的可见光和不可见光信号均被两个光敏传感器24所接收,两个光敏传感器24将所接收到的反射光信号分别转换为电信号后,再将两个光敏传感器24转换得到的电信号一起叠加合并后传送给模拟信号处理芯片144进行信号放大、整流滤波和信号模数变换,识别和放大信号中的有效信息,去除信号中的杂质和无效信息,再将净化过滤后的有效信息发送给微处理器142,由微处理器142根据存储器143内已固设好的心率、血氧饱和度运算软件所给定的运算方法,将此输入的电信号计算转换为标准格式的心率和血氧饱和度指标,并输出给显示屏12以及手持移动终端设备。
为了使其测量更加准确,需要在带上手环后,使腕带2,尤其是腕带2处的测量印制板22对手腕部位有一定的接触压力,为此本实施方式还在腕带2上设置了张紧装置26,其张紧装置26采用一个插销配多个扣眼的可调节方式,根据佩戴者手腕粗细的不同,由用户手动自行调整腕带的张紧度,通过该张紧装置26能将其接触压力调整至合适的范围内,当然张紧装置26还可以采用弹性材料制成,弹性材料能根据不同用户的手腕粗细自动调整腕带的长度以及腕带对手腕部位的压紧力。
本实施方式在主体1的主印制板141上设置了计步用重力加速度传感器16,从而进一步增加了本实施方式的参数采集范围,丰富了产品的功能,使其能够在用户散步或跑步的过程中记录其行经的步数,依据用户的步长由微处理器142根据存储器143内已固设好的步行距离及热量消耗运算软件计算得出所行经的距离及用户为此消耗的热量。
本实施方式在主体1的主印制板141上还设置了报警装置18,当各项测得值与存储器143内预设的标准值相比,已超出健康指标参数的范围时,微处理器142便指令报警装置18发出警报,提醒用户注意健康并采取相应的措施。
本实施方式将包含有微处理器142、存储器143、模拟信号处理芯片144和蓝牙传输装置145的主控系统设置在了主体1内,又将主体1设置在手环的上部,在戴带后即位于人体手背侧的手腕上面的外关穴E附近;将装配有体表温度传感器23、光敏传感器24和光源25等测量部件的测量印制板22设置在了腕带2上,并将测量印制板22设置在手环的下部,在戴带后即位于人体掌心侧的手腕下面的内关穴F附近;测量印制板22和主控系统通过设置在腕带上的柔性连接线缆21进行电连接,由于人体手腕下面的血管丰富,脉博明显,此处反映的健康信息较为丰富,在此处采集人体健康参数,能大大提升测取数据的准确度。
