Description

婴幼儿睡眠诱导装置 技术领域
本申请涉及睡眠诱导装置，尤其涉及一种用于安抚或者诱导婴幼儿入睡的装置。
背景技术
入睡困难可能导致压力，疾病或由诸如失眠的病症引起。睡眠不好的影响会影响工作性能和生活质量。同样，在儿童和婴儿中诱导睡眠是同样重要和同样具有挑战的。类似地，老年人，特别是那些在社区生活环境中的老年人，经常经历比一般人群甚至更大的睡眠困难。另外，当患者需要旅行和/或试图在不熟悉的环境中睡眠时，睡眠或入睡的困难常常被放大。
数字睡眠诱导装置可通过播放预先录制的舒缓音乐和柔和的自然声音来帮助诱导深度睡眠。这种设备的问题在于它们具有固定的频率和节奏，并且用户往往会厌倦它们。
US20090105524A1公开了一种用于嵌入音乐的，诱导更好睡眠的设备，其速度约为每分钟60至80拍。以大约每分钟60到80个节拍的速度听音乐可以显着改善睡眠质量，改善感知的睡眠质量，延长睡眠时间并提高睡眠效率。该设备的实施例可以尤其包括闹钟，枕头，手机，睡眠面罩，婴儿床或与儿童一起使用的填充玩具。还考虑了包括旅行时钟、旅行枕头或移动设备的设备实施例，该设备允许容易地运输该设备以在旅行期间引起更好的睡眠。
US20090105524A1中教导了通过反复向婴儿提供由如上所述的根据本申请的用于诱导婴儿睡眠的系统稳定的母亲的心跳声音，给婴儿一种母亲与婴儿待在一起的心理稳定感，可以有效地诱导并延长睡 眠状态持续时间。
US20090105524A1中描述的诱导睡眠的装置的一个发明构思在于，其外壳可以根据特定的使用人群来定制，例如，特别是对于婴儿而言，可以套在枕头或者可爱的玩具来。
而且，US20090105524A1未公开特定的与测量心率有关的采样、微控制器单元或模块的配置或细节，它披露的是测量心跳声音，而非心率。其中，滤波单元124-1仅仅传递20至200Hz范围的声音，该声音范围是一般心跳声音的范围。除心跳声音之外的其它声音由过滤单元124-1过滤掉。测量单元130是麦克风(高度灵敏的麦克风传感器)，并根据听诊器原理测量心跳。由于在婴儿睡觉时提供了母亲的心跳声音，由于母亲与婴儿在一起的心理稳定感，有效地诱导了睡眠并延长了睡眠状态持续时间。
在US20090105524A1中，The A/D转换器124连接在连接到测量装置130的主体连接端子120a和控制单元123之间。由测量装置130测量的心跳声音通过模数转换器124传输到控制单元123。模数转换器124将由测量装置130测量的心跳声音的模拟信号转换成数字信号。滤波器单元124-1可以进一步连接到模数转换器124。测量装置130仅测量模拟信号，测量装置130本身并不直接处理模拟信号或将该模拟信号转换为数字信号，而是经由传输模拟信号的电缆将模拟信号传输给被垫子主体110包裹的操作主体单元120中的A/D转换器124。
KR1020200064288A公开了一种睡眠监测和睡眠诱导装置，该睡眠监测和睡眠诱导装置可以包括：通信单元，用于接收由所述睡眠活动感测设备检测到的用于所述用户的睡眠活动的信号；以及睡眠状态分析单元，被配置为基于检测到的周围环境来分析用户的睡眠状态；以及感觉刺激输出单元，其基于检测到的周围环境来刺激用户的感觉。该睡眠监测和睡眠诱导装置基于检测到的周围环境来生成关于用户身体的信息，可基于对睡眠状态的分析来监测用户的睡眠状态和周 围环境，并且可以通过刺激用户的睡眠质量来增加用户的感觉。
在现有技术中，例如在US20090105524A1中，如上所述，测量装置130本身并不直接处理模拟信号，也不将该模拟信号转换为数字信号，而是将模拟信号经由模拟信号传输电缆传送给与测量装置130相连的A/D转换器124。A/D转换器124连接在连接到诸如探头等测量装置130的主体连接端子120a与控制单元123之间。由测量装置130测量的心跳声音(模拟信号)通过模数转换器124传输到控制单元123。模数转换器124将由测量装置130测量的心跳声音的模拟信号转换成数字信号。滤波器单元124-1可以进一步连接到模数转换器124。也就是说，测量装置130采取信号后并非就地在测量装置130上进行处理，而是由连接在测量装置130与模数转换器124之间的模拟信号电缆传递该模拟信号(非数字信号)给例如A/D转换器124。
连接在测量装置130与模数转换器124之间的该电缆的使用环境的电磁噪声比较复杂，例如在存在多重电磁噪音的家庭室内或者室外，电磁噪声的辐射或传导(EMI)可能会严重干扰机电设备的正常工作。
模拟信号的主要优点是其精确的分辨率，在理想情况下它具有无穷大的分辨率，可以对自然界物理量的真实值进行尽可能逼近的描述。但是，模拟信号的本质缺点是噪声效应会使模拟信号产生有损。有损后的模拟信号几乎不可能再次被还原，因为对所需信号的放大会同时对噪声信号进行放大。模拟信号总是受到杂讯(信号中不希望得到的随机变化值)的影响。模拟信号被多次复制，或进行长距离传输之后，这些随机噪声的影响可能会变得十分显著。为了提高信噪比，需要在模拟信号传输过程中及时对衰减的传输信号进行放大，模拟信号在传输过程中不可避免地叠加上的噪声也被同时放大。随着传输距离的增加，噪声累积越来越多，以致使传输质量严重恶化。
相比之下，数字信号抗干扰能力强、无噪声积累。由于数字信号的幅值为有限个离散值(通常取两个幅值)，在传输过程中虽然也受到 噪声的干扰，但当信噪比恶化到一定程度时，即可在适当的距离采用判决再生的方法，从而可再生成没有噪声干扰的和原发送端一样的数字信号。所以，数字信号可实现长距离高质量的传输。
另外，数字信号便于加密处理，便于存储、处理和交换。并且，数字信号的通信处理设备便于集成化和微型化。数字信号的通信采用时分多路复用，不需要体积较大的滤波器。通信处理设备中大部分电路是数字电路，可用大规模和超大规模集成电路实现，因此数字信号的通信处理设备还具有体积小、功耗低的优点。这显然有利于进一步降低设备成本和运行的鲁棒性。
数字通信的信号形式和计算机所用信号一致，都是二进制代码，因此便于与计算机联网，也便于用计算机对数字信号进行存储、处理和交换，可使通信网的管理、维护实现自动化、智能化。
这样，现有的装置不得不采用造价昂贵的EMC屏蔽电缆，此时电缆需要带屏蔽层来防止电气线路上的电磁噪声干扰，保护自身的信号不受干扰，但这会使睡眠诱导装置的总体成本增加；或者，现有的装置退而求其次使用普通的没有EMC屏蔽措施或EMC屏蔽效果不佳的电缆，这毫无疑问降低了睡眠诱导装置的性能表现。
与无线通信相比，数字有线通信的信号传输质量更高更可靠，更不容易受阻挡或者干扰。无线数字通讯的优点也是显而易见的，更加灵活方便且物理干扰少。
就此方面而言，现有技术需要更好的方案来解决这一技术问题，并通过利用数字信号通信和处理来实现更多的优势。
本申请的说明书的此背景技术部分中所包括的信息，包括本文中所引用的任何参考文献及其任何描述或讨论，仅出于技术参考的目的而被包括在内，并且不被认为是将限制本申请范围的主题。

实例I
如图1所示，该睡眠诱导装置包括主机，以及通过通讯线路20与主机通讯连接的集成式探头模块或探头组件。该主机包括主控芯片1、与之相连的存储器3、音频处理电路4、功率放大电路5、显示屏7以及可用于输入指令/参数的小键盘8。主机外壳可采用对安全的塑料制成，并且可根据需要成形为便于用手握持的大小和形状，或者也可以设置成便于婴幼儿怀抱或把玩的形式，比如可以套在抱枕或者玩具中，等等。主机接收至少来自集成式探头模块或探头组件2的例如母亲心率等数字化信息数据，可选地进行处理，并将音频信号经由功率放大电路并通过例如扬声器输出给婴幼儿，诱导婴幼儿快速进入良好的睡眠状态。
采样探头2设计成集成式探头模块或探头组件2的形式，包括用于采样的心率传感器以及与处理该集成式探头模块或探头组件2信号的信号处理电路，特别是用于将采样得到的模拟信号转换为数字信号的模数转换器或模数转换电路。
集成式探头模块或探头组件2至少包括心率传感器，以检测婴幼儿母亲的心率。该心率感测装置可以是红外心率感测装置，或者是血氧型、光电容量型、心电信号型或动脉血压型的感测装置。
根据本申请，一种心率传感器的示例可以是红外心率感测装置，即，红外探头。红外线心率计可通过红外线传感器检测出手指中动脉血管的微弱波动，由计数器计算出每分钟波动的次数。将红外发光二极管产生的大约760nm至400μm波长范围内的红外线照射到人体的血管位置,通过红外光对血管的透射或反射，血液的流动信号返回到接收管，经过模块电路调试，由接收管传感器采集脉搏信号，经过前置放大、滤波、单片机进行处理后可以得出人体的实时心率值。诸如红外传感器之类的光电传感器受的干扰源比较多，如环境光、暗电流、气流的变化、人体的运动、人体的移动、呼吸的变化、人体的紧张程 度、环境的变化情况、人体的血液流动情况、人体皮肤的厚度、血管的流畅情况、天气的状况等等，针对干扰需要有对应的适当算法来处理。
一种示例性的红外心率感测装置例如可参加2005年2月7日申请的中国实用新型专利CN2776292Y，其全部内容通过引用结合于本申请中。
此外，集成式探头模块或探头组件2还可集成有或单独地设置或单独地设置温度传感器，用于测量体温。
集成式探头模块或探头组件2另外还可增设集成其它类型的传感器，用于感测婴幼儿体位、血氧饱和度，呼吸频率，等等。在很多情形下，婴儿在睡眠时的生命体征参数状态(例如体温，血氧饱和度，心率，呼吸率)，并传送给主机，这对于婴儿的父母来说具有更多的实际意义和更高的关注价值。这样，一方面可以降低没有自理能力的婴儿发生体位不正造成窒息和持续高烧的风险，另一方面也可以对婴儿促进和/监测睡眠质量。
重要的是，集成式探头模块或探头组件2集成了用于处理由集成式探头模块或探头组件2感测到的母亲心跳(包含心率信息)模拟信号的信号处理电路，特别是用于将采样到的模拟信号转换为数字信号的模数转换器或模数转换电路。
这样，模拟信号在集成式探头模块或探头组件2内部被处理并转换成数字信号经由通讯线路20输出。这样，与现有技术比较而言，彼此独立的主机与集成式探头模块或探头组件1之间进行通讯的通讯线路20就不必采用价格昂贵的专用设计的铠装电路的形式，而是可以直接使用市面上容易得到的、造价便宜但信号传输稳定高质量的常见的硬线，例如USB数据线。
显示器一般是小型的液晶/LED/OLED显示屏7，可显示各类操作/控制状态，指令和反馈，等等。特别是，OLED又称为有机电激光显示、有机发光半导体，OLED显示屏具有自发光、广视角、几乎无穷 高的对比度、较低耗电、极高反应速度等优点。一般而言，显示屏7也是集成、例如镶嵌在主机上且与主机的相关元器件和电路可操作地连接。
类似地，小键盘8集成在主机上且与主机的相关元器件和电路可操作地连接，用于输入指令和/或数据，可控制和调整主机的元器件/电路。
扬声器6集成在主机上且与主机的相关元器件和电路可操作地连接，用于播放音频输出，例如实时或非实时的母亲心率、安抚声音，音乐，等等。功率放大器电路5可直接连接到扬声器6。
存储器3存储来自主机主控芯片1的数据、参数和音频，和向主控芯片1发送所调取的数据。
根据一示例，主机还可包含低压差调节器，用来向主控芯片提供稳定的电压。
主机的供电电源可包含直接与民用供电电源(如家用插座接电源)相连的电源适配器，或者可直接采用蓄电池，例如可充电的锂电池，等等。
同样，集成式探头模块或探头组件2优选可采用独立的电池供电，例如可充电的电池，如纽扣电池，等等。
主控芯片1可包括CPU、第二存储器、音频处理电路和功率放大器电路，等等。来自通讯线路20的心跳如心率信号可被临时存储在第二存储器中，由声音处理电路转换后输出到显示屏7。功率放大器电路直接连接到扬声器。
功率放大器电路5是用于放大并输出更大功率的放大电路，直接连接到扬声器6，如微型喇叭，并驱动扬声器6。
音频处理电路4被配置为解码和合成音频数据。
主机一侧设有接口。通过该接口，主控芯片1经由通讯线路20连接到集成式探头模块或探头组件2。
供电电源、如蓄电池，可内置于婴幼儿睡眠诱导装置之内。作为 附加或者备选，电源接口例如可位于婴幼儿睡眠诱导装置的表面处靠近电池的位置。
功率放大器电路5可经由电线电连接到扬声器6。
根据一示例，还可在主机中设置无线接收器，用于与诸如移动电话的设备通信。
当使用现有的婴儿睡眠诱导装置时，存在某些缺点。仅以固定频率播放的预先录制的心跳声音，可能无法真实地、及时地反映和更新来自母亲的心跳和心律。通过本申请的婴幼儿睡眠诱导装置播放采集并经过处理的例如来自母亲的真实的、及时更新的心跳(如心律)声音，模拟婴儿在母亲腹部的环境，这使婴儿更容易入睡。
实例II
实例II基本上与实例I相同。不同之处在于如下所述。
作为实例I中的通讯线路20采用有线通信方式的替代或者附加，通讯线路20可替代或附加采用无线数字通信。
在该实施例的婴幼儿睡眠诱导装置的主机中设置无线通讯模块，该无线通讯模块配置成在工作时以无线的方式接收来自集成式探头模块或探头组件2的数字化的信息和参数如心律信息，该无线通讯模块采用蓝牙或低功耗低辐射的2.4G/433MHZ无线数据通讯的方式。对应地，在集成式探头模块或探头组件2上集成相应的蓝牙或2.4G/433MHZ无线数据通讯模组。这种通讯方式被证明是对婴幼儿的健康无实质性风险，可以安全的方式保障婴儿的睡眠和健康。
婴幼儿睡眠诱导装置的主机中的无线通讯模块与集成式探头模块或探头组件2中的无线数据通讯模组之间经由信号传输线路20进行通信的距离，一般在0-500米的范围内，优选在0-50米、更优选在0-20米的范围内。这样，一方面能够保证婴儿的健康安全，另一方面能够保证通讯的可靠性、稳定性，和可能的高质量的信号反馈。
特别是，433HMz接收灵敏度较高，绕射性好，在相同参数下， 相比其他频率，433HMz的传输距离更远。433HMz是国内免许可的ISM开发的频率，不需要向当地无线电管理授权，所以能在市场上被广泛应用。在要求组网容易、配置简单、成本低，使用环境复杂的应用场合，433MHz的无线模块的一种很好的选择，因此特别适合于婴儿安抚和监护场合。在433MHZ的无线传输通讯方式下，可以非常可靠地传输各种信号，包括传感器信号，比如信号感知、处理、无线传输，等等。这种433MHZ无线传输可以实现比较理想的传输距离可达2Km，最大甚至可达4-10Km。
作为本实例的通信方式的附加，也可以在设置无线通讯模组之外，在集成式探头模块或探头组件2设置信号传输线路20的硬线连接接口。
在本实例中，集成式探头模块或探头组件2中的心率传感器采用血氧类型的传感器，并借助于确定血氧饱和度水平的算法来获得相关的数据输出。关于该血氧类型的心率传感器的例子可参加本申请人在美国专利申请US20200101261A1中所描述的那些，该美国申请描述的内容通过引用结合于本申请中，但那些与本申请相背离或相矛盾的描述除外。
实例III
实例III的方案与上述任一项实例的技术方案基本上相同。不同之处在于如下所述。
一般而言，大脑在深睡时，其脑电信号频率小于4Hz；在浅睡时，其频率为4Hz-8Hz；在放松状态时频率为8Hz-13Hz；在觉醒时一般大于13Hz，且随着频率的升高，意识越清醒。
实例III在主机中增设集成了根据所需的诱导睡眠的频率或频段发送脉冲电磁场的睡眠诱导模块，该睡眠诱导模块可根据特定的设置，例如可以小于4Hz、4Hz-8Hz等的频率发送脉冲电磁场作用于婴幼儿对象，以诱导其进入所需的睡眠状态，例如深睡状态或浅睡状态。
出于说明的目的而提出了对本申请的对若干个实施例的前文描述。所述前文描述并非意图是穷举的，也并非将本申请限于所公开的特定特征和/或形式。
显然，根据上文的教导，可做出许多修改和变型，这些都属于本申请的范围内。本申请的范围仅由所附权利要求来限定。所附权利要求书旨在覆盖所有这样的修改和变型。
