本发明的实施方式
下面通过具体实施方式结合附图对本申请作进一步详细说明。其中不同实施方式中类似元件采用了相关联的类似的元件标号。在以下的实施方式中，很多细节描述是为了使得本申请能被更好的理解。然而，本领域技术人员可以毫不费力的认识到，其中部分特征在不同情况下是可以省略的，或者可以由其他元件、材料、方法所替代。在某些情况下，本申请相关的一些操作并没有在说明书中显示或者描述，这是为了避免本申请的核心部分被过多的描述所淹没，而对于本领域技术人员而言，详细描述这些相关操作并不是必要的，他们根据说明书中的描述以及本领域的一般技术知识即可完整了解相关操作。
另外，说明书中所描述的特点、操作或者特征可以以任意适当的方式结合形成各种实施方式。同时，方法描述中的各步骤或者动作也可以按照本领域技术人员所能显而易见的方式进行顺序调换或调整。
本文中为部件或对象所编序号本身，例如“第一”、“第二”等，仅用于区分所描述的对象，不具有任何顺序或技术含义。而本申请所说“连接”、“联接”，如无特别说明，均包括直接和间接连接（联接）。
目前，医院的无线网络通常会存在盲点区域，这些盲点区域的网络信号较差，或者存在某些干扰，当携带移动式医疗设备和可穿戴式医疗设备的病人活动到这些区域时，这些医疗设备与中央监护站的网络连接可能会断开，此时医生无法通过中央监护站实时观测病人的身体状况，给病人的生命安全造成了一定的威胁。因此，需要通过某些技术手段精确的定位出医院无线网络中的盲点区域，从而进行优化，避免医疗事故的发生，成为医院急需解决的问题之一。
对无线网络的状态进行分析可以是通过分析网络分析工具所在主机到某个网络设备的最大响应时间、最小响应时间、网络设备可用性等参数，形成网络报告。但这种工作方式存在如下几个缺点：1）这种测试方式所形成的网络报告只是整个无线网络的整体运行概述报告，无法精确定位网络问题；2）这种测试方式无法精确定位无线网络的盲点区域所在位置。
基于此，提出本申请的方案。在本申请实施例中，无线医疗设备和中央监护站通过无线接入点接入无线网络并通过该无线网络进行通信；无线医疗设备采集患者的至少一种生理参数信号并处理，得到患者的生理数据，同时还监测其所在无线接入点的网络状态信息，得到第一网络状态信息；无线医疗设备通过无线网络向中央监护站发送得到的生理数据和第一网络状态信息；中央监护站至少显示该生理数据和对第一网络状态信息进行存储。
参见图1，提供了一种监护仪的结构示意图，该监护仪可以具有独立的外壳，外壳面板上可以具有传感器接口区，其中传感器接口区可以集成多个传感器接口，用于与外部的各个生理参数传感器附件111连接，外壳面板上还可以包括小型IXD（交互设计）显示器区、显示器119、输入接口电路122和报警电路120（如LED报警区）等。参数处理模块具有用于与主机进行通讯和从主机取电的对外通讯和电源接口116。参数处理模块还可以支持外插参数模块，可以通过插入参数模块形成插件式监护仪主机，作为监护仪的一部分，也可以通过电缆与主机连接，外插参数模块作为监护仪外置的一个配件。
参数处理模块的内部电路置于外壳内，如图1所示，包括参数测量电路112、前端信号处理器113和主处理器115，参数测量电路112至少包含心电信号参数测量电路、呼吸参数测量电路、体温参数测量电路、血氧参数测量电路、无创血压参数测量电路、有创血压参数测量电路等等中的至少一个参数测量电路，每个参数测量电路分别通过相应的传感器接口与外部插入的传感器附件111连接。参数测量电路112的输出端耦合到前端信号处理器113，前端信号处理器113的通讯口耦合到主处理器115，主处理器115与对外通讯和电源接口116电连接。传感器附件111包括用于心电呼吸、血氧、血压、体温等生理参数检测所对应的检测附件。参数测量电路112主要是用来连接传感器附件111获得采集的生理参数信号的。各种生理参数对应的传感器附件111和参数测量电路112可采用现有技术中的通用电路，前端信号处理器113完成参数测量电路112输出信号的采样和模数转换，并输出控制信号控制生理信号的测量过程，这些参数包括但不限于：心电，呼吸，体温，血氧，无创血压和有创血压参数。前端信号处理器113可采用单片机或其它半导体器件实现，例如可以选用PHLIPS公司的LPC2136，或者ADI的ADuC7021等混合信号单片机，也可以采用ASIC或FPGA实现。前端信号处理器113可由隔离电源供电，采样得到的数据经过简单处理打包后，通过隔离通讯接口发送至主处理器115，例如前端信号处理器113可以通过隔离电源和通讯接口114耦合到主处理器115上。前端信号处理器113由隔离电源供电的原因是通过变压器隔离的DC/DC电源，起到了隔离患者与供电设备的作用，主要目的是：（1）隔离患者，通过隔离变压器，将应用部分浮地，使患者漏电流足够小；（2）防止除颤或电刀应用时的电压或能量影响主控板等中间电路的板卡及器件（用爬电距离和电气间隙保证）。当然，前端信号处理器113还可以通过电缆124与主处理器115连接。主处理器115用于完成生理参数的计算，并通过对外通讯和电源接口116将参数的计算结果和波形发送到主机（如带显示器的主机、PC机、中央监护站等等）；其中主处理器115可以通过电缆125与对外通讯和电源接口116连接以进行通讯和/或取电；参数处理模块还可以包括电源和电池管理电路117，电源和电池管理电路117通过对外通讯和电源接口116从主机取电，并经过处理后供应给主处理器115，例如整流和滤波等；电源和电池管理电路117还可以对通过对外通讯和电源接口116从主机所取得的电进行监测、管理和供电保护。对外通讯和电源接口116可以是以太网（Ethernet）、令牌环（Token Ring）、令牌总线(Token Bus)以及作为这三种网的骨干网光纤分布数据接口（FDDI）构成的局域网接口中的一个或其组合，还可以是红外、蓝牙、wifi、WMTS通讯等无线接口中的一个或其组合，或者还可以是RS232、USB等有线数据连接接口中的一个或其组合。对外通讯和电源接口116也可以是无线数据传输接口和有线数据传输接口中的一种或两种的组合。主机可以是监护仪的主机、心电图机、超声诊断仪、计算机等任何一个计算机设备，安装配合的软件，就能够组成一个监护仪。主机还可以是通讯设备，例如手机，参数处理模块通过蓝牙接口将数据发送到支持蓝牙通讯的手机上，实现数据的远程传输。主处理器115完成生理参数的计算后，还可判断生理参数是否异常，若异常，可以通过报警电路120进行报警。存储器118可以存储监护仪的中间和最终的数据，以及存储用于被主处理器115等执行的程序指令或代码。若监护仪具有血压测量的功能，则还可以包括一个泵阀驱动电路121，泵阀驱动电路121用于在主处理器115的控制下进行充气或放气操作。
如图2所示，提供一种医院内使用的监护仪联网系统，利用该系统可以将监护仪的数据进行整体保存，集中管理病人信息和看护信息，两者进行关联存储，便于进行历史数据的保存和关联报警。在图2所示的系统中，针对病床均可以提供一个床边监护仪212，该床边监护仪212可以是前述多参数监护仪或者插件式监护仪。另外，每个床边监护仪212还可以与一个便携式监护设备213进行配对传输，便携式监护设备213提供简便、可携带的参数处理模块，可是穿戴在病人身体上对病人进行移动式监护，通过便携式监护设备213与床边监护仪212进行有线或无线通讯后可以将移动式监护产生的生理数据传输到床边监护仪212上进行显示，或通过床边监护仪212传输到中央监护站211供医生或护士查看，或通过床边监护仪212传输到数据服务器215进行存储。另外，便携式监护设备213还可以直接通过设置在院内的无线网络节点214将移动式监护产生的生理数据传输到中央监护站211进行存储和显示，或者通过设置在院内的无线网络节点214将移动式监护产生的生理数据传输到数据服务器215进行存储。可见，床边监护仪212上显示的生理参数对应的数据可以是源自直接连接到监护以上的传感器附件，或者源自便携式监护设备213，或者源自数据服务器。
前述用于执行各个步骤的各个单元或模块中的每一个可以存储在一个或多个前述存储器中，而上述实施例中分别用于实现前述的监护仪或监护系统中，其中各个功能模块中包括每一个用于执行上述方法中相应步骤的指令集，上述模块或程序（即指令集）不需要时限为分立软件程序、过程或模块，因此，在各个实施例中可以组合或重新安排这些模块的各个子块，因此，在本发明的一些实施例中存储器可以存储如上所述的模块或数据结构的子集。
参见图3，为本申请实施例提供的一种无线医疗监护系统的结构示意图，该无线医疗监护系统包括至少一个无线医疗设备01、无线接入点02、无线控制单元03和中央监护站04。
其中，无线接入点02用于提供无线连接热点，无线控制单元03与无线接入点02组成无线网络，用于控制无线接入点02；无线医疗设备01和中央监护站04通过无线接入点02接入无线网络，无线医疗设备01和中央监护站04通过该无线网络进行通信，无线医疗设备01可以接受中央监护站04的管理和监测。
无线医疗设备01用于采集患者的至少一种生理参数信号，比如心电、呼吸、体温、血氧、无创血压和有创血压等生理参数信号，对采集的生理参数信号进行处理，得到患者的生理数据；无线医疗设备01同时监测其所在无线接入点02的网络状态信息，得到第一网络状态信息；无线医疗设备01通过无线网络向中央监护站04发送无线医疗设备01得到的生理数据和第一网络状态信息。中央监护站04至少用于显示该生理数据和对无线医疗设备01监测到的第一网络状态信息进行存储。

这样，无线医疗设备01不但可以执行患者生理参数的监测进程，还可以同时执行无线网络监控进程，监测其所在无线接入点02的网络状态信息，并使用同一个无线网络将患者的生理数据和监测到的第一网络状态信息发送给中央监护站04，患者生理参数的监测进程和网络监控进程共用同一个无线网络，实现了对无线网络的网络状态信息的实时监测。中央监护站04可以存储无线医疗设备01监测到的第一网络状态信息，以便对该第一网络状态信息进行进一步的分析，形成网络分析报告。
实际应用中，无线接入点02和无线控制单元03可以是两个不同的设备，也可以是一个同时具备无线接入点功能和无线控制功能的专用设备。
一种实施例中，中央监护站04获取到无线医疗设备01监测到的第一网络状态信息后，还用于对该第一网络状态信息进行分析，得到无线网络分析结果。一种实施例中，可以将该第一网络状态信息保存在网络日志文件中。例如，在一种实施例中，无线医疗设备01可以定时通过无线网络向中央监护站04发送第一网络状态信息，中央监护站04会检测第一网络状态信息的值是否发生变化，如果第一网络状态信息中的至少一个信息发生了变化，则将当前接收到的第一网络状态信息记录到网络日志文件中。在另一种实施例中，中央监护站04可以在接收到无线医疗设备01发送的第一网络状态信息后，无论该第一网络状态信息是否发生变化，都将该第一网络状态信息记录到网络日志文件中。
一种实施例中，中央监护站04可以在判断出分析目录中存在网络日志文件时，对该网络日志文件中的数据进行分析，得到网络事件，然后根据预设规则对该网络事件进行分析，得到无线网络分析结果。其中的网络事件至少包括无线医疗设备的上下线事件，无线网络分析结果至少反映无线网络的掉线情况。
具体的，中央监护站04可以设置至少一个分析目录，该分析目录可以用来存储和管理网络日志文件。中央监护站04可以显示无线网络分析界面，该无线网络分析界面中包括用于选择分析目录的第二菜单，检测用户在该无线网络分析界面中的操作，根据用户在无线网络分析界面上对第二菜单的操作确定分析目录。例如，无线网络分析界面的一种显示效果可参见图4，用户可在“分析目录”菜单中点击文件夹图标，找到分析目录的存储路径，从中选择分析目录。具体的，当需要执行无线网络分析功能时，用户可以通过中央监护站04启动无线网络分析工具，此时中央监护站04可以在其显示界面上显示无线网络分析界面，用户可以在该无线网络分析界面中通过第二菜单选择网络日志文件所在的分析目录，确定好之后，中央监护站04判断所选分析目录中是否存在网络日志文件，若存在，则对所选分析目录中的网络日志文件中的数据进行分析，得到网络事件，然后根据预设规则对该网络事件进行分析，得到无线网络分析结果。
中央监护站04在根据预设规则对网络事件进行分析时具体用于：基于设定的网络分析时长内的网络事件，统计无线医疗设备01符合设定条件的掉线情况。
其中，设定的网络分析时长比如可以是一天、两天、一周、两周等时间段，中央监护站04可以根据设定的时间段内的网络事件统计无线医疗设备01的掉线情况。一种实施例中，可以由用户在无线网络分析界面中设定网络分析时长。具体的，中央监护站04可以在其显示界面上显示无线网络分析界面，该无线网络分析界面中包括用于设定网络分析时长的第一菜单，中央监护站04检测用户在该无线网络分析界面中的操作，根据用户在该无线网络分析界面上对第一菜单的设定操作确定网络分析时长。例如，在如图4所示的无线网络分析界面中，用户可以在“网络分析时长”菜单中设定网络分析时长，用户可以直接输入网络分析时长，或者通过下拉菜单选择网络分析时长，比如设定网络分析时长为“一天”，中央监护站04对所选分析目录中的网络日志文件中的数据进行分析，得到网络事件之后，则可以从最近一天内的网络事件中统计出无线医疗设备01符合设定条件的掉线情况。
其中，统计无线医疗设备01符合设定条件的掉线情况可以包括如下至少之一：（1）统计无线医疗设备01每天掉线的总时长；（2）针对每一天，对于每一个设定时长范围，统计隶属于该设定时长范围内的每一次掉线时长，其中的设定时长范围比如可以是小于或等于15s、大于15s且小于60s和/或大于或等于60s，则以天为单位，统计无线医疗设备01在一天内小于或等于15s的各掉线时长，统计无线医疗设备01在一天内大于15s且小于60s的各掉线时长，统计无线医疗设备01在一天内大于或等于60s的各掉线时长；（3）针对每一天，统计无线医疗设备01在每一个设定周期内的掉线次数，比如，以天为单位，对于每一天，统计无线医疗设备01每个小时的掉线次数，或者每两个小时的掉线次数等；（4）针对每一天，统计无线医疗设备01掉线时的信道利用率落入信道利用率阈值范围内的掉线次数，比如，以天为单位，对于每一天，统计无线医疗设备01掉线时的信道利用率大于60%时的掉线次数，统计无线医疗设备01掉线时的信道利用率在40%至60%时的掉线次数，统计无线医疗设备01掉线时的信道利用率小于40%时的掉线次数等；（5）针对每一天，统计无线医疗设备01每次掉线时所在无线接入点的信息。
一种实施例中，中央监护站04得到无线网络分析结果之后，可以将该无线网络分析结果记录到文件中，以便用户对该无线网络分析结果进行查看和分析。
一种实施例中，中央监护站04得到无线网络分析结果之后，还用于根据该无线网络分析结果生成图形化报告。这样，对于不具备网络相关知识的用户也能看懂分析结果，以便进一步优化无线网络。具体的，该图形化报告可以包括无线医疗设备01掉线时长阈值内外分布图、无线医疗设备掉线时所在无线接入点的次数分布图、无线医疗设备掉线时间区域分布图、无线医疗设备掉线时所在信道利用率分布图、无线医疗设备掉线次数分布图和无线医疗设备24小时掉线次数分布图中至少之一。
具体的，对于掉线时长阈值内外分布图，中央监护站04可以对第一网络状态信息进行分析，得到无线医疗设备01的掉线情况，判断每一次的掉线时长是否落入掉线时长阈值内，以此统计出落入掉线时长阈值内的各个掉线时长，统计出落到掉线时长阈值外的各个掉线时长，然后根据统计结果得到掉线时长阈值内外分布图，该掉线时长阈值内外分布图可以是以天为单位进行统计得到的每一天的分布图。例如，中央监护站04可以根据上述统计无线医疗设备01符合设定条件的掉线情况中的情况（2）对该网络事件进行分析，得到无线医疗设备01在一天内大于15s且小于60s的各掉线时长，即统计出落入掉线时长阈值内（大于15s且小于60s）的各个掉线时长，同时得到小于或等于15s的各掉线时长及大于或等于60s的各掉线时长，即统计出落到掉线时长阈值外的各个掉线时长，进而以此得到无线医疗设备01在这一天的掉线时长阈值内外分布图。
中央监护站04可以对第一网络状态信息进行分析，统计无线医疗设备01每次掉线时所在无线接入点的信息，比如，可以以天为单位执行统计分析，以此得到无线医疗设备01掉线时所在无线接入点的次数分布图。用户通过该分布图可以看出各个无线接入点的掉线情况，分析各个无线接入点的故障。
中央监护站04可以对第一网络状态信息进行分析，统计无线医疗设备01每一次掉线时的时间，以此得到无线医疗设备01掉线时间区域分布图。用户可根据该掉线时间区域分布图进一步分析判断无线医疗设备01的掉线原因。
中央监护站04可以对第一网络状态信息进行分析，统计无线医疗设备01掉线时的信道利用率落入信道利用率阈值范围内的掉线次数，比如掉线时的信道利用率大于60%时的掉线次数、掉线时的信道利用率在40%至60%时的掉线次数和掉线时的信道利用率小于40%时的掉线次数，以此得到无线医疗设备01掉线时所在信道利用率分布图。通过该分布图可以获知无线医疗设备01掉线时无线网络的忙闲情况。
中央监护站04可以对第一网络状态信息进行分析，统计无线医疗设备01在每一个设定周期内的掉线次数，比如每两个小时的掉线次数、每一天的掉线次数等，以此可以得到无线医疗设备01的掉线次数分布图，根据该分布图可以分析无线医疗设备01的故障情况。也可以得到无线医疗设备01的24小时掉线次数分布图，根据该分布图可以分析携带无线医疗设备01的患者的走动情况。
一种实施例中，中央监护站04在生成图形化报告之后，还可以保存该图形化报告，图形化报告的保存路径可以是预先设置好的，也可以由用户进行设置。
具体的，中央监护站04可以在其显示界面上显示无线网络分析界面，该无线网络分析界面中可以包括用于保存图形化报告的保存菜单，中央监护站04检测用户在无线网络分析界面中的操作，根据用户在无线网络分析界面上对该保存菜单的操作将图形化报告按照选定的保存路径进行保存。例如，在如图4所示的无线网络分析界面中，用户可以在“分析报告保存路径”菜单中设置图形化报告的保存路径，设置好之后可以点击“保存”按钮，此时中央监护站04会根据设置好的保存路径保存图形化报告。
一种实施例中，如图4所示，无线网络分析界面中还可以包括“分析”功能键和/或“版本”功能键，当“分析”功能键被触发后，中央监护站04启动对网络日志文件中的数据进行分析的功能，可以使用户手动启动本申请提供的无线网络分析功能。当然，中央监护站04也可以自动启动无线网络分析功能，比如，中央监护站04可以在接收到第一网络状态信息后自动进行无线网络分析。用户可以通过触发“版本”功能键来了解当前网络分析工具（运行于中央监护站04，提供本申请的无线网络分析功能）的版本、版权等信息。
一种实施例中，中央监护站04还可以实现邮箱功能，在生成图形化报告之后，可以通过邮箱将图形化报告发送给用户。比如，中央监护站04可以为用户提供邮箱设置功能，允许用户设置接收报告的邮箱地址，中央监护站04在生成图形化报告之后，可以根据该邮箱地址向用户发送图形化报告，比如可以是生成图形化报告后即时发送，也可以是定期发送。
一种实施例中，中央监护站04还可以定时采集无线接入点02的网络状态信息，得到第二网络状态信息，此时可以对网络日志文件中的数据和该第二网络状态信息进行综合分析，得到无线网络分析结果。其中的第二网络状态信息可以包括MAC地址（Media Access Control Address，媒体存取控制位址）、BSSID、IP地址（Internet Protocol Address，互联网协议地址）、名称、位置、编号、信道、信道利用率、干扰信息中的一种或多种。
具体的，中央监护站04判断分析目录中是否存在中央监护站04采集的第二网络状态信息，若存在，则对该第二网络状态信息进行分析，获取无线接入点02的BSSID和名称的映射关系并缓存，当判断出分析目录中存在网络日志文件时，综合该映射关系对网络日志文件中的数据进行分析；若分析目录中不存在中央监护站04采集的第二网络状态信息，则当判断出分析目录中存在网络日志文件时对该网络日志文件中的数据进行分析。
