[0027] 在本实施例中, 所述离床跟踪装置 1包括, 但不仅限于, 通信单元 11、 微处理 器 12、 计时器 13、 心率传感器 14、 扬声器 15以及定位单元 16。 所述通信单元 11 、 计时器 13、 心率传感器 14、 扬声器 15以及定位单元 16均通过信号线连接至所 述微处理器 12上。 所述压力传感器 2的数量可以为一个或多个, 本实施例优选为 四个压力传感器 2, 分别设置在监护床的四个床脚底部, 分别用于测量监护床的 每一个床脚的分压力信号, 并将每一个床脚的分压力信号发送至所述信号耦合 器 3。
[0028] 所述信号耦合器 3设置在床头或者床体边缘的任一位置处, 用于将每一个床脚 的分压力信号进行信号耦合得到床体的总压力信号, 并将床体的总压力信号发 送至所述离床跟踪装置 1上。 在本实施例中, 所述信号耦合器 3包括信号接收单 元 31、 信号耦合单元 32以及信号发送单元 33。 每一个压力传感器 2通过有线连接 方式 (例如信号导线) 连接至所述信号接收单元 31上, 所述信号接收单元 31通 过所述信号耦合单元 32连接至所述信号发送单元 33上。 所述信号接收单元 31用 于接收每一个压力传感器 2所测量到的分压力信号, 所述信号耦合单元 32用于将 所述多个分压力信号进行信号耦合得到床体的总压力信号, 所述信号发送单元 3 3将所述床体的总压力信号发送至所述离床跟踪装置 1的通信单元 11上。 所述信 号发送单元 33通过无线连接方式 (例如蓝牙) 连接至所述离床跟踪装置 1上。

[0030] 所述微处理器 12用于将所述床体的总压力信号转换为床体压力值, 并根据所述 床体压力值判断用户是否离床。 在本实例中, 当所述床体压力值趋于零时, 所 述微处理器 12确定用户已经离床。 当用户已经离床, 所述微处理器 12启动所述 计时器 13计算用户的离床吋间, 并从所述心率传感器 14获取用户的心率数据。
[0031] 所述微处理器 12还用于判断用户的离床时间是否超过预设时间 (例如 15分钟) , 当用户的离床时间未超过预设吋间, 所述微处理器 12控制扬声器 15发出语音 信息提示用户上床休息。 当用户的离床时间超过预设吋间, 所述微处理器 12根 据用户的心率数据判断用户的心率是否正常。 一般情况下, 成人正常心率为 60 〜100次 /分钟, 理想心率应为 55〜70次 /分钟。 如果心率超过 160次 /分钟或低于 40 次 /分钟, 所述微控制器 12则确定用户的心率不正常, 用户可能发生呼吸暂停或 者是心肌梗塞的病危情况。
[0032] 当用户的心率不正常吋, 所述微控制器 12启动定位单元 16获取用户的位置信息 , 产生一条包含用户位置信息的报警信息, 并将该报警信息通过所述通信单元 1 1发送至监护者的移动通信终端 (例如监护者或医生的手机) 或医疗监护中心的 医疗监护平台上, 以供监护者或医生实时地了解用户的离床情况, 并釆取急救 措施对心率不正常的用户 (例如呼吸暂停或者是心肌梗塞的用户) 进行紧急救 护, 以防止意外病情发生。 此外, 由于报警信息中含有用户位置信息, 因此监 护者或医生能够快速寻找到长时间离床的用户 (例如梦游) 的具体位置, 从而 便能最大限度地避免救护不及时的情况而发生意外。
[0033] 如图 2所示, 图 2是本发明基于物联网的离床监护系统优选实施例的应用系统架 构图。 在本实施例中, 所述应用系统包括离床监护系统 10、 移动通信终端 20、 路由器 21以及医疗监护平台 30。 所述离床监护系统 10通过无线网络 40连接至所 述移动通信终端 20以及路由器 21, 该路由器 21通过远程通信网络 50连接至所述 医疗监护平台 30。 所述无线网络 40包括但不仅限于, 蓝牙、 WiFi等无线传输网 络, 所述远程通信网络 50包括伹不仅限于, GSM网络、 GPRS网络、 CDMA等无 线传输网络。 所述离床监护系统 10应用于所述监护床上, 所述移动通信终端 20 包括, 但不仅限于, 手机、 个人数字辅助设备 (PDA) , 掌上电脑等无线通讯 设备。 所述医疗监护平台 30为一种设置在医疗监护中心的远程监控设备或服务 器。
[0034] 在本实施例中, 所述离床监护系统 10用于实时监测用户的离床情况, 当用户长 吋间离床且心率不正常吋, 产生包含用户位置信息的报警信息并通过所述路由 器 21将所述报警信息发送至医疗监护平台 30, 以供医生对长吋间离床的病危用 户 (例如呼吸暂停或者是心肌梗塞等) 釆取紧急救护措施。 当用户长时间离床 但心率正常时, 产生提醒信息并通过所述路由器 21将所述提醒信息发送至监护 人的移动终端设备 20, 以提醒监护者及时照看长吋间离床的非病危用户, 防止 用户长吋间离床梦游情况发生。
[0035] 本发明所述离床监护系统 10将用户的离床信息及心率数据发送至路由器 21 , 再 由路由器 21发送至远程的医疗监护平台 30进行存储, 从而实现了心率数据与医 疗监护中心对接, 实现了医生对用户离床情况的远程同步监护。 因此使得医生 能够全天二十四小吋不间断地监测用户的离床情况。 此外, 由于采用了外部的 路由器 21作为离床信息及心率数据到远程的医疗监护平台 30上, 从而降低了本 发明所述离床监护系统 10的硬件配置需求, 既节省了成本又实现用户离床情况 的远程同步监护。
[0036] 此外, 本发明还提供了一种基于物联网的离床监护方法, 应用于离床监护系统 10中, 能够结合用户的心率数据实时监测用户的离床情况, 对于长时间离床且 心率不正常的用户, 产生报警信息并将该报警信息发送至医疗监护平台 30, 对 于长时间离床但心率正常的用户, 产生提醒信息提醒用户上床休息并将提醒信 息发送至监护人的移动终端设备 20, 以防止用户长时间离床发生意外情况。
