Description

人体通信系统和基于人体通信系统的健康服务网络
【技术领域】
本发明涉及健康服务网络，特别涉及一种基于人体通信系统的健康服务网络。
【背景技术】
目前，疾病早预防、早干预及早治疗观念已经逐渐被大家所接收，这对减轻老百姓看病难、看病贵等问题提出了一个可能性的解决方案。上述“三早”观念的实现的关键技术就是要对人体的各种生理参数进行不间断地、实时监测，并有可能进行干预。电子通信技术的发展使上述方案成为可能，其设计必须满足以下条件：（1）传输方式对使用者的身体健康没有负面影响；（2）数据传输必须稳定且不受人的身体影响；（3）工作功耗低使得系统能长期工作；（4）通信保密性好；（5）数据率不能太低；（6）服务提供者与服务接收者能随时随地通信。
但现有的通信技术中，蓝牙和Zigbee通信距离比较远，容易在不同的人体间造成覆盖区域重叠，这样就降低了系统安全性和减少了系统的吞吐量；蓝牙和WiFi的功耗高，而Zigbee的数据率太低；RFID与NFC的数据率也太低，且组网不容易。另外，上述的RF无线技术都要面临着无线通信中的“阴影效应”的影响，导致在人体运动中相关部位的通信大尺度衰落，造成系统的实时性和健壮性受到影响。因此，采用上述通信技术，造成了人体生理参数监测中最看重的功耗、安全性、通信健壮性等性能大打折扣。同时，传统的监测侧重于个体，个体与个体之间的交换（例如医生与病人当面的交流等）必须通过不同网络的路由或直接操作终端设备等，导致个体之间的通信繁冗，使其大众化和可操作性受到影响。
【发明内容】
本发明要解决的技术问题之一是提供一种由体积小、通信效率高的节点组成的人体通信系统。
本发明要解决的另一个技术问题是提供一种基于人体通信系统可随时随地提供服务的健康服务网络。
为解决上述技术问题，本发明提供一种人体通信系统，包括若干可分布于人体内及体外的各部分的节点，所述节点之间以人体作为介质进行通信，并根据需要形成相应的网络拓扑结构；所述节点包括用于生理参数监测与健康方面的穿戴式或植入式设备、通信接口、以人体为通信介质的人体通信收发器和电极，所述穿戴式或植入式设备与所述人体通信收发器通过通信接口连接，所述人体通信收发器与所述电极相连接，所述人体通信收发器接收电极上的数据，并将数据通过电极发送出去，所述人体通信收发器的工作频率小于100MHz。
本发明还提供一种健康服务网络，包括：
分布于人体的若干节点形成的人体通信系统，所述节点包括用于健康方面的穿戴式或植入式设备，所述节点之间以人体作为介质进行通信，并根据需要形成相应的网络拓扑结构；
一具有远程通信功能的个人电子设备；及
至少一局域网或广域网中的健康服务终端，所述健康服务终端和所述个人电子设备之间经由网络建立连接，所述人体节点获得的信息在人体进行传播后经由所述个人电子设备传送至健康服务终端，所述健康服务终端发送的信息经由网络和个人电子设备在人体进行传播后传送至人体节点。
本发明的有益技术效果在于：该人体通信系统将人身体作为通信媒介，通过耦合或者感应方式进行通信，使得通信范围局限于人体近端通信，具有高安全性及高频带利用率，同时具有功耗低及无阴影效应等优点。该健康服务网络以人体通信系统为基础，人体通信系统是每个人自己的专属健康网络，能随时随地被健康服务提供者访问，建立了一种健康服务提供者（例如医生、健康中心工作人员等）和健康服务接收者（患者、病人等）之间的立体通道，从而建立了一种立体的健康服务网络。
【附图说明】
图1为本发明健康服务网络一较佳实施例的示意图；
图2为本发明健康服务网络一较佳实施例中人体通信系统节点的结构框图。
【具体实施方式】
图1是本发明一较佳实施例，其提出了一种新的健康服务网络。这种新的健康服务网络包括人体通信系统、具有远程通信功能的个人电子设备和若干处于局域网或广域网中的健康服务终端。通过该具有远程通信功能的个人电子设备，该人体通信系统和该健康服务终端实现网络连接。
该人体通信系统由若干分布于人体内及体外的各部分的节点构成。各节点设有不同的穿戴式或植入式设备。这些穿戴式或植入式设备包括各类生理参数监测设备和各类用于健康方面的执行设备。例如，检测设备包括心电、血糖、血氧饱和度、呼吸率、血压检测仪，及胶囊内窥镜等。执行设备包括心脏起搏器、电子耳蜗、胃刺激器等。
如图2所示，每一节点还包括有人体通信收发器、通信接口和通信电极。前面所讲的穿戴式或植入式设备与人体通信收发器通过通信接口连接，该通信接口包括各类高速、低速接口，例如SPI、 UART、I2C、并口、USB等。人体通信收发器与电极相连接。人体通信收发器之间通过电极传输数据。人体通信收发器通过电极接收数据以及通过电极发送数据。通信收发器包括发送端和接收端，其发送端采用调制（或基带）的方式发送数据，其接收端采用解调的方式接收数据。人体通信收发器工作在低频（小于100MHz），输出功率符合人体安全标准。电极为各类绝缘电极和非绝缘电极，可以与人体随身携带的物品相融合。例如，融合的物品可以是人的饰品，包括手表、手机、耳机、眼镜、耳钉等，也可以是人的衣服、腰带、鞋子等其它可以在人身上佩戴的东西。该电极具有导电特性，其可以通过绝缘材料包裹。电极与人体通信收发器通过导体连接，或电极直接在人体通信收发器上。
节点可以在人身上各部分相应的位置放置，一起构成基于人体通信的人体通信系统（或躯干网），各节点之间以人体作为介质，通过耦合或者感应方式进行通信。采用该通信方式，使得通信范围局限于人体近端通信，具有高安全性及频带利用率，同时具有功耗低及无阴影效应等优点。由于人体通信功耗极低，使其节点比以往的节点功耗更低，且人体通信不需要天线，这样可以使节点的体积很小，更适合于穿戴式和植入式应用。而且，节点电极可以与人的随身物品相结合，佩戴更加舒适、自然。
各节点共同形成的基于人体通信的人体通信系统，根据应用需要，可以采用星形、树型、网状等不同的网络拓扑结构。
同时，个体之间也可以通过握手等身体接触来建立人体通信链路。例如，医生需要知道患者的实时身体状况，可以通过握手请求与患者建立通信链路，在患者同意的情况下，下载患者身上的生理数据，并存入到医生自身的数据记录器中进行分析、诊断。
个人电子设备与持有该个人电子设备的人体上的节点通过人体介质传输数据。躯干网的数据在人体进行传播后，通过具有远程通信功能的个人电子设备（例如手机、PDA、掌上电脑）发往局域网/广域网。健康服务终端和个人电子设备之间经由局域网或广域网连接。
在医院、健康管理中心、急救中心等机构里设置各种健康服务终端。经由局域网/广域网，健康服务终端和人体通信系统通过个人电子设备可以随时随地地建立连接。这样，健康服务提供者就可以与服务接受者之间随时随地地建立连接来提供服务。
健康服务终端里具有各种数据库模块，该数据库模块存储有各种健康服务数据，当然也可存取健康服务接受者的数据。在为服务接受者服务时，除可以依据服务提供者个人的技能之外，还可以调取各种健康服务数据以及链接局域网/广域网中的其它数据库模块，来提供更全面准确的服务。
以上所述仅为本发明的较佳可行，并非限制本发明的保护范围，凡运用本发明说明书及附图内容所作出的等效结构变化，均包含在本发明的保护范围内。
