背景技术
人体成分是指人体内脂肪、肌肉、蛋白质、矿物质等成分的含量,可以评价人体的发育、成熟和衰老状况,在监测儿童发育、指导健美减肥、以及医疗保健等方面具有重要意义。
常用的人体成分检测方法有双能X射线吸收法(dual energy X-ray absorptiometry,DEXA)和生物电阻抗分析法(bioelectrical impedance analysis,BIA)。DEXA通过对不同能级的X射线穿过人体骨骼和软组织的吸收和衰减进行测量,得到人体成分,该方法准确度高,但有辐射,且价格昂贵。人体内通过不同的微弱电流时,人体内的脂肪、肌肉等成分具有不同的导电性,产生不同的人体阻抗。因此,BIA利用测量的阻抗,结合人的性别、年龄、身高、体重等信息,计算出各种人体成分的含量。BIA测量方法简单,使用方便,是专业级体脂秤和家用体脂秤的主要测量方法。
基于BIA的人体成分检测准确度取决于阻抗测量结果,而人体阻抗检测的准确度受皮肤体表湿度影响很大,当用户脚部和手部出汗时,或者用户在运动、洗澡后,希望第一时间看到减脂效果进行体成分测量时,由于脚部、手部表面含有汗液或水分,会出现很大的阻抗测量误差,从而导致人体成分检测结果不准确。

具体实施方式
本申请实施例提供一种人体成分检测设备和方法,该人体成分检测设备基于BIA检测人体成分。基于BIA的人体成分检测由于测量方法简单,使用方便,受到了广泛的应用,常见的人体成分检测设备有专业体脂秤和家用体脂秤。
人体成分检测设备可以为脚部测量设备,也可以为手部测量设备,还可以包括脚部测量设备和手部测量设备。BIA人体成分检测准确度取决于阻抗测量结果,而人体阻抗检测的准确度受皮肤体表湿度影响很大,当用户脚部或者手部出汗、有水,例如,用户在运动之后手部和脚部出汗,或者,用户在洗澡、洗漱之后手部或者脚部沾有水,此时进行测量人体阻抗测量结果的误差较大。
现有技术中,通常在人体成分检测设备的说明书中增加“建议”和“提醒”信息,比如“避免在运动、洗澡后使用”,提示用户避免在脚部或者手部出汗、有水的情况下使用人体成分检测设备。
用户在运动、洗澡后立即使用人体成分检测设备是一个主要的应用场景,通常用户在运动或洗澡后希望第一时间看到减脂效果进行体成分测量,因此,在用户脚部或者手部出汗时,如何避免或者提高人体成分检测的准确性是一个急需解决的问题。
为了解决现有技术的问题,本申请实施例提供一种人体成分检测设备,该人体成分检测设备具有除湿功能,能够在测量人体阻抗之前除去人体接触部位(手部或者脚部)上的水分,保证人体阻抗测量结果准确,从而能够提高人体成分检测的准确性。
该人体成分检测设备可以与手机、平板电脑、可佩戴设备、个人电脑等终端设备配合使用,终端设备通过安装的人体成分检测app与人体成分检测设备进行通信和交互,例如,终端设备对人体成分检测结果进行显示,用户还可以通过终端设备对人体成分检测设备进行设置。
图1为人体成分检测设备的一种外部结构示意图,如图1所示,该人体成分检测设备100包括外壳2、支撑层(位于外壳内部,图中未示出)和4个检测器:检测器101、检测器102、检测器103和检测器104。4个检测器以检测设备100的中心为中心,对称分布在周围。
可以理解,图1仅为一种示例,检测设备100还可以包括更多或者更少的检测器。
每个检测器包括阻抗测量组件和除湿组件,支撑层包括处理器,阻抗测量组件和除湿组件均与处理器电连接,阻抗测量组件、除湿组件和支撑层均设置在外壳内部。阻抗测量组件的上表面平行或者高于外壳的上表面,阻抗测量组件的上表面在测量时与人体接触。
其中,除湿组件用于对阻抗测量组件接触的人体表面进行除湿。阻抗测量组件用于在除湿组件完成除湿后测量人体阻抗。处理器,用于根据阻抗测量组件测量得到的人体阻抗进行处理得到人体成分,输出人体成分。或者,处理器将阻抗测量组件测量得到的人体阻抗发送给对检测设备100控制的终端设备(例如为手机),由该终端设备对人体阻抗进行处理得到人体成分,并输出人体成分。
在使用图1所示检测设备100测量时,人体双脚踩在检测设备100上,检测设备100通过体重被唤醒,可以开始测量。当用户只测量体重时,可以穿鞋袜踩在检测设备100上,并且用户脚部的踩踏位置不做限定。当用户需要测量人体成分时,需要光脚踩在检测设备上,不能穿鞋袜,并且用户脚部的踩踏位置需要在固定位置,示例性的,人体左脚踩在检测器101和检测器103上,人体右脚踩在检测器102和检测器104上。否则无法进行测量,或者可能导致测量结果不准确。
在使用检测设备100测量人体成分时,由以下两种场景:场景一、由检测设备100独立完成人体成分测量,并输出人体成分。场景二,如图2所示,由检测设备100和连接的终端设备200配合进行测量,并由终端设备200输出人体成分。

图3(b)界面上显示有电子秤的缩略图和使用提示信息,该使用提示信息例如为“请赤脚轻踩上秤”,用户踩上检测设备100之后,点击该电子秤的缩略图触发测量,检测设备100将测量得到人体阻抗后,将人体阻抗发送给终端设备200,终端设备200对人体阻抗进行处理得到人体成分,并通过图3(c)所示界面显示人体成分测量结果。如图3(c) 所示,该人体分体成分的测量结果中包括身体得分、身体年龄、当前体重、脂肪率、水分率、基础代谢率、蛋白质、肌肉量等等。可选的,还显示有目标体重,以及当前体重与目标体重的差值。
可选的,在场景二中,检测设备100将测量得到人体阻抗后,也可以由检测设备100对人体阻抗进行处理得到人体成分,并将人体成分发送给终端设备200进行显示。
场景一中,由于检测设备100的显示屏较小,可能无法将人体成分测量结果完整显示在一屏内,此时,可以采用滚动显示的方式,依次显示各人体成分的测量结果。
可选的,检测器可以采用基于电流、电压的阻抗测量方式,在采用基于电流、电压的阻抗测量方式时,需要形成电流回路。图1所示检测设备100中,检测器101和检测器102的两个阻抗测量组件的电极构成电流回路,电流从检测器101流入人体,经过人体从检测器102流出人体。检测器103和检测器104的两个阻抗测量组件的电极用于测量电压。阻抗测量组件根据电流和测量得到的电压计算得到人体阻抗。
本实施例中,除湿组件除湿的过程中可能与人体表面接触,也可能不与人体表面接触,除湿过程中除湿组件是否与人体接触与除湿组件的结构或者除湿方式相关。该除湿组件可以通过加热、吹风或者吸水等一种或者多种方式进行除湿,本实施例不对此进行限制。

可选的,在检测设备100启动后,该除湿组件可以自动触发对接触的人体表面进行除湿,除湿结束后,阻抗测量组件开始测量人体阻抗。除湿组件可以按照预设的除湿时间进行除湿,除湿时间结束后结束除湿,默认人体表面干燥,可以进行人体阻抗测量。该除湿时间可以采用系统默认值,也可以由用户灵活设置,用户通过终端设备上的人体成分测量APP或者体脂称APP对除湿时间进行设置。
图4为设置除湿时间的界面示意图,如图4所示,用户在体脂称APP中打开如图4(a)所示的设置界面,该设置界面中包括以下设置项:体重单位、家庭成员、闹钟提醒、目标体重、帮助和关于等。用户通过“体重单位”设置项可以设置体重的单位为千克(kg)或者磅(lb)等。用户通过“家庭成员”设置项可以增加多个成员,实现对成员体脂以及人体成分的测量和管理。用户通过“闹钟提醒”设置可以设置人体成分的测量时间等,用户通过“目标体重”设置项可以设置用户想要达到的体重值。用户通过该“除湿时间”设置项可以设置除湿时间。

可选的,在本申请实施了中可以在每个检测器上设置一个湿度测量组件,也可以只在部分检测器上设置湿度测量组件。例如,检测设备包括4个检测器,可以只在其中一个检测器上设置湿度测量组件,或者,在其中两个检测器上设置湿度测量组件,或者,在4个检测器上均设置湿度测量组件。
测度测量组件要对人体表面进行湿度测量,需要接触人体表面。由于阻抗测量组件的上表面在测量时也需要与人体接触,可选的,可以将湿度测量组件嵌入在阻抗测量组件上,湿度测量组件的上表面与阻抗测量组件的上表面位于同一平面内,从而保证湿度测量组件的上表面与阻抗测量组件的上表面均可以与人体表面接触的同时,可以保证测量时的舒适度。
该测量条件要求例如为湿度值大于或等于预设的湿度阈值时需要进行除湿。示例性的,在检测设备100唤醒后,湿度测量组件开始测量人体表面的湿度,当测量得到的湿度值大于或等于预设的湿度阈值时,处理器确定对人体表面进行除湿,并控制除湿组件开始除湿。当测量得到的湿度值小于预设的湿度阈值时,处理器确定不对人体表面进行除湿。可选的,终端设备200可以基于与检测设备100相同的测量条件要求决定是否进行除湿,当然,终端设备还可以基于其他条件决定是否进行除湿,本申请实施例不对此进行限制。
一种可选的实现方式中,处理器确定对人体表面进行除湿(包括检测设备自己确定以及终端设备确定)之后,可以控制除湿组件按照预设的除湿时间进行除湿,除湿时间结束后结束除湿,该除湿时间可以采用系统默认值,也可以由用户在终端设备上进行灵活设置后动态发送给检测设备。
另一种可选的实现方式中,处理器可以根据测量得到的湿度值确定除湿时间,或者,终端设备根据测量得到的除湿值确定除湿时间,将除湿时间发送给检测设备,检测设备的处理器控制除湿组件按照该除湿时间进行除湿,除湿时间结束后结束除湿。
再一种可选的实现方式中,湿度测量组件在除湿组件除湿过程中,持续对人体表面的湿度进行测量,当测量得到的湿度值满足阻抗测量组件的测量条件要求时,控制除湿组件结束除湿操作。例如,当测量得到的湿度值小于预设的湿度阈值时,停止除湿。
可选的,该湿度测量组件包括一个或者多个湿度传感器。湿度传感器可以采用微机电 系统(Micro-Electro-Mechanical System,MEMS)触感器。
当检测设备100包括脚部测量设备时,脚部测量设备可以通过体重唤醒(或者启动),需要进行测量时,用户站立在检测设备100上,当检测设备100检测到重量且所检测到的重量大于设定的阈值时,检测设备100启动,阻抗测量组件、除湿组件和处理器可以开始运行。本实施例只是举例说明,检测设备100还可以使用其他启动方式,例如,语音唤醒,用户可以通过语音方式输入预设唤醒指令,又如,通过检测设备100上的固定按键唤醒。可选的,该固定按键可以是物理按键或者虚拟按键。

可选的,当测量得到的湿度值大于或等于预设的湿度阈值时,处理器还用于输出第一提示信息,第一提示信息用于提示是否进行除湿,当接收到用户根据第一提示信息输入的确认除湿的指令时,通过除湿组件进行除湿。
处理器可以通过如下几种方式输出第一提示信息:
方式一,当检测设备100包括显示屏时,将第一提示信息发送给显示屏进行显示。用户可以通过显示屏上的虚拟按键或者物理按键选择是否进行除湿,或者,用户通过语音方式输入除湿指令,检测设备100可以通过麦克风采集用户输入的声音信号,处理器对声音信号进行识别得到该除湿指令,该除湿指令为确认除湿指令或者否认除湿指令,确认除湿指令用于指示检测设备100进行除湿,否认除湿指令用于指示检测设备100不进行除湿。

可以理解,图5和图6只是一种示意图,第一提示信息和选择控件还可以以其他形式表示。
当检测设备100接收到用户根据第一提示信息输入的否认除湿指令时,可选的,处理器还可以输出第二提示信息,第二提示信息用于提示用户擦干水分之后进行检测。例如,通过检测设备100的显示屏显示第二提示信息,或者,通过终端设备的显示界面显示第二提示信息。示例性的,第二提示信息为“为保证准确性,请擦干手脚后重新测量”。

手部检测设备和脚部检测设备可以通过该有线方式或者无线方式进行通信,实现测量数据的交换。通常情况下,脚部检测设备可以用于检测体重和人体阻抗,而手部检测设备只能用于检测人体阻抗,手部检测设备可以将检测得到的人体阻抗通过有线或者无线方式发送给脚部检测设备。脚部检测设备对人体体重、自身测量得到的人体阻抗和手部检测设备测量得到的人体阻抗进行处理得到人体成分。
可选的,脚部检测设备也可以将人体体重、自身测量得到的人体阻抗和手部检测设备测量得到的人体阻抗发送给与脚部检测设备连接的手机或者其他电子设备,以手机为例,手机接收到人体体重、脚部检测设备测量得到的人体阻抗和手部检测设备测量得到的人体阻抗后,对人体体重、脚部检测设备测量得到的人体阻抗和手部检测设备测量得到人体阻抗进行处理,得到人体成分。

本申请实施例三提供一种基于吸水方式除湿的人体成分检测设备,除湿组件采用干燥圈。图16为基于吸水方式除湿的人体成分检测设备的检测器的爆炸示意图,图17为图16所示人体成分检测设备的检测器的外观的侧视图,参考图16和图17,检测器1包括阻抗测量组件11、干燥圈17、支撑层13、湿度测量组件14和压力传感器15。本实施例中,检测设备100的外壳2包括上壳21和下壳22。
其中,阻抗测量组件11呈弧形凸起结构,干燥圈17围设在阻抗测量组件11的四周,干燥圈17的上表面低于或者平行与阻抗测量组件11的外边缘,从而能够形成坡度,使得人体表面的水滴能够从阻抗测量组件11的顶端滚落至干燥圈17,干燥圈17吸收水分。
本实施例中,阻抗测量组件11、上壳21,以及支撑层13从上到下层叠设置,阻抗测量组件11和上壳21上分别开设有通孔,阻抗测量组件11、上壳21上开设的通孔的大小相同,且通孔的中心对齐,湿度测量组件14安装在通孔内,湿度测量组件14的下端与支撑层13电连接,湿度测量组件14的上端从下到上依次穿过上壳21和阻抗测量组件11。

在对人体成分进行测量时,湿度测量组件14的上表面以及阻抗测量组件11的上表面均需要与人体表面接触,因此,本实施例中,设置湿度测量组件14的上表面与阻抗测量组件11的上表面位于同一平面内,阻抗测量组件11的上表面平行或者高于上壳21的上表面,从而能够保证在对人体成分进行测量时,人体表面能够与湿度测量组件14的上表面以及阻抗测量组件11的上表面接触。可选的,湿度测量组件14的上表面略高于阻抗测量组件11的上表面。
支撑层13中包括处理器、连通引线等(图中未示出)。
可选的,压力传感器15安装在支撑层13下方。示例性的,压力传感器15的下表面的中心凸起,该凸起穿过下壳22上的孔洞。压力传感器15的安装方式参照实施例一的相关描述,这里不再赘述。
可选的,阻抗测量组件11为圆形结构,干燥圈17的形状与阻抗测量组件11相同,干燥圈17围设在阻抗测量组件11周围。可以理解,阻抗测量组件11和干燥圈17也可以采用除圆形外的其他形状。
在一个可选的实施例中,干燥圈17和阻抗测量组件11可以为多对,干燥圈17和阻抗测量组件11呈多层间隔设置,最内层为阻抗测量组件11,最外层为干燥圈17,当然多层干燥圈17和阻抗测量组件11的高度从内向外依次降低,从而能够保证水滴从高处滚落至干燥圈。
本实施例的人体成分检测设备,包括干燥圈17和湿度测量组件14,在检测设备被唤醒之后,干燥圈17对人体表面进行除湿,湿度测量组件14开始测量人体表面的湿度,当测量得到的湿度值不满足测量条件要求时,阻抗测量组件11不进行阻抗测量,湿度测量组件14在除湿过程中,继续测量人体表面的湿度,当测量得到的湿度值满足测量条件要求时,阻抗测量组件11开始进行阻抗测量。通过干燥圈17对人体表面进行除湿,在人体表面水分被去除之后,才进行人体阻抗测量,从而提高了人体阻抗的测量的准确性,进而能够提高通过人体阻抗进行人体成分检测的准确性。

可选的,在除湿完成后,人体成分检测设备还可以输出第三提示信息,第三提示信息用于提示开始测量人体阻抗。示例性的,第三提示信息为“开始测量人体阻抗”或者“手部或者脚部水分清理干净”或者“手部或者脚部水分清理干净,开始测量人体阻抗”。
在本申请其他可能的实施例中,在除湿完成后,不输出第三提示信息,人体成分检测设备默认开始测量人体阻抗。
S1303、对测量得到的人体阻抗值进行处理,得到人体成分。
