 本发明的实施方式
下面通过具体实施方式结合附图对本发明作进一步详细说明。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。因此，说明书和附图中的各种顺序只是为了清楚描述某一个实施例，并不意味着是必须的顺序，除非另有说明其中某个顺序是必须遵循的。
本文中为部件所编序号本身，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）。
本发明提供一种床旁互联系统，其包括多个床旁医疗设备。多个床旁医疗设备均通过床旁互联系统的通信网络通信。床旁医疗设备可以包括监护仪、心电图机、超声成像设备、麻醉机、呼吸机、输注泵和除颤仪中的一种，可见，多个床旁医疗设备组成一床旁互联系统，可实现多个床旁医疗设备之间的互联互通。
在建立床旁互联系统时，一个床旁医疗设备与另一床旁医疗设备建立通信连接，所述一个床旁医疗设备通过预设的验证信息与所述另一床旁医疗设备建立绑定关系，从而组成初始的床旁互联系统。验证信息可以是NFC（近场通信）信息，即两个床旁医疗设备通过近场通信即可建立绑定关系。验证信息也可以是扫码信息，即一个床旁医疗设备通过扫描另一床旁医疗设备的二维码或条形码等，即可建立绑定关系。验证信息也可以是蓝牙信息，两个床旁医疗设备通过蓝牙连接从而建立绑定关系。验证信息也可以是用户手动输入的ID或配对码，一个床旁医疗设备验证另一个床旁医疗设备的ID或配对码，验证通过则建立绑定关系。当然，验证信息还可以是其他的数据或信息，只要能确保床旁医疗设备安全可控的绑定即可。
床旁互联系统添加床旁医疗设备时，床旁互联系统中的一个床旁医疗设备与待添加的床旁医疗设备建立通信连接，并通过预设的验证信息与待添加的床旁医疗设备建立绑定关系，以将待添加的床旁医疗设备加入床旁互联系统，具体的过程同上述建立床旁互联系统的过程，在此不做赘述。
床旁互联系统中，每一床旁医疗设备分别与至少一个床旁医疗设备建立通信连接（物理连接，可以是无线连接，也可以是有线连接），形成通信网络，使得床旁互联系统中任意两个床旁医疗设备之间均具有对应的通信通路。通信通路包括多个节点，每个节点对应一床旁医疗设备，所述多个节点中的每一个节点与相邻的两个节点之间的通信连接相同或不同。如图1所示，第一床旁医疗设备10和第二床旁医疗设备20之间的通信通路包括：通信连接a、节点30、通信连接c、节点40和通信连接f。本发明不限定任意两个床旁医疗设备之间的通信连接方式，例如，通信连接可以包括以太网连接、无线网络WIFI连接、无线医疗遥测服务WMTS连接、蓝牙连接、红外连接、串口连接、物联网IoT连接、控制器局域网络CAN连接和通用串行总线USB连接中的至少一个。例如，第一床旁医疗设备10和第三床旁医疗设备30之间的通信连接为蓝牙连接，第三床旁医疗设备30与第四床旁医疗设备40之间的通信连接为无线网络WIFI连接等，本发明不限定。
由于床旁互联系统中可能存在多种通信连接方式，不同于传统的通信组网方式，故需要对互联和通信做出改进。本发明提供两种方式，下面一一介绍。
第一方式，数据的传输采用遍历的方式，如图1实施例中，第一床旁医疗设备10向相邻的所有床旁医疗设备（只有第三床旁医疗设备30）发出第一请求。第三床旁医疗设备30接收到第一请求时判断自身是否满足第一请求；当第三床旁医疗设备30判断自身满足第一请求时，第三床旁医疗设备30响应第一请求；当第三床旁医疗设备30判断自身不满足第一请求时，第三床旁医疗设备30通过通信网络转发第一请求，例如转发给相邻的所有床旁医疗设备（第七床旁医疗设备70和第四床旁医疗设备40）。第七床旁医疗设备70和第四床旁医疗设备40接收到第一请求后，同样判断自身是否满足第一请求，若满足则响应，不满足则转发给相邻的所有床旁医疗设备。依次类推，直到所有床旁医疗设备都接收到第一请求，完成了第一请求的传输。此时，要么系统中至少有一个床旁医疗设备响应了第一请求，要么系统中没有任何一个床旁医疗设备能响应第一请求。此种方式中，信息的传输效率不高，故本发明提供第二方式。
第二方式中，各个床旁医疗设备识别床旁互联系统的拓扑结构，根据拓扑结构确定通信通路，从而有针对性的进行信息传输，提高了通信效率，具体过程如图4所示，包括：
步骤01、每个床旁医疗设备向相邻（拓扑结构上的相邻，即直接连接在一起的床旁医疗设备）的床旁医疗设备发送自身的设备信息，也即各个床旁医疗设备向自身各个通信连接发送它自己的设备信息。设备信息可以是用于唯一标识床旁医疗设备的信息，如ID、设备名称、型号等。
步骤02、每个床旁医疗设备通过自身的各个通信连接（至少有一个通信连接）接收相邻床旁医疗设备发出的设备信息，识别出自身的每个通信连接可达的床旁医疗设备的设备信息，并记录下来，即。例如图1的例子中，第三床旁医疗设备30识别出来其通信连接a可达第一床旁医疗设备10，通信连接b可达第七床旁医疗设备70，通信连接c可达第四床旁医疗设备40。
步骤03、每个床旁医疗设备向相邻的床旁医疗设备发送其记录的通信连接以及通信连接可达的床旁医疗设备的设备信息，换而言之，每个床旁医疗设备通过自身的各个通信连接发送：其他通信连接可达的床旁医疗设备的设备信息（即床旁医疗设备记录的各个通信连接可达的床旁医疗设备的设备信息）。例如图1的例子中，第四床旁医疗设备40向通信连接c发送：通过第四床旁医疗设备40的通信连接d可达第六床旁医疗设备60，通信连接e可达第五床旁医疗设备50，通信连接f可达第二床旁医疗设备20。
步骤04、每个床旁医疗设备，即，对于床旁互联系统中的任一床旁医疗设备，所述床旁医疗设备接收相邻床旁医疗设备发送的相邻床旁医疗设备的每个可达床旁医疗设备的设备信息；所述床旁医疗设备记录到达所述相邻床旁医疗设备的通信连接的信息和对应的每个可达床旁医疗设备的设备信息。即，所述床旁医疗设备更新记录的通信连接及其可达的床旁医疗设备的设备信息，之后返回步骤03，即重复步骤03和04，直至记录的每个通信连接的可达床旁医疗设备的设备信息没有变化。如此，每个床旁医疗设备记录有所有的通信连接及其可达的床旁医疗设备的设备信息，即每个床旁医疗设备都得到了整个床旁互联系统的拓扑结构信息；从而有利于后续通信过程中规划通信通路。拓扑结构信息中，通信连接及其可达的床旁医疗设备的设备信息是关联的，便于规划通信通路。
床旁互联系统中若新增了床旁医疗设备，为便于叙述，以第三床旁医疗设备30新绑定了一个床旁医疗设备（第七床旁医疗设备70）为例进行说明。第三床旁医疗设备30与第七床旁医疗设备70建立了通信连接b，第三床旁医疗设备30记录通信连接b可达的第七床旁医疗设备70的设备信息，即更新了床旁互联系统的拓扑结构信息。第三床旁医疗设备30可以将通信连接b（通信连接信息）以及通信连接b可达的第七床旁医疗设备70的设备信息发送给相邻的床旁医疗设备（如10、40和70），即，可以采用步骤03和04的方式，经过一个或多个循环后，让所有床旁医疗设备（包括第七床旁医疗设备70）的拓扑结构信息得到更新。当然第三床旁医疗设备30也可以将其更新后的拓扑结构信息广播给所有床旁医疗设备（包括第七床旁医疗设备70），从而让所有床旁医疗设备的拓扑结构信息得到更新。由此，可以方便的新增床旁医疗设备，实现即插即用。
本发明后续将以第二方式为例，展开说明。床旁互联系统的床旁医疗设备的数据处理方法有多种，下面一一介绍。如图2所示，一种数据处理方法至少涉及两个床旁医疗设备，为便于描述，将其称之为第一床旁医疗设备10和第二床旁医疗设备20，即，如图1所示的床旁互联系统中，至少包括第一床旁医疗设备10和第二床旁医疗设备20。图2所示的数据处理方法包括如下步骤：
步骤1、当第一床旁医疗设备10触发预设事件时，第一床旁医疗设备10通过通信网络向多个床旁医疗设备中与预设事件对应的床旁医疗设备发出第一信息。由于第一床旁医疗设备10和第二床旁医疗设备20均为所述多个床旁医疗设备中的一个，两者在通信通路上可以是相邻的，也可以不相邻，本实施例以后者为例进行说明。将第一床旁医疗设备10和第二床旁医疗设备20之间的一个床旁医疗设备称之为第三床旁医疗设备30，则步骤1中，第一床旁医疗设备10通过通信网络和床旁互联系统中的第三床旁医疗设备30向所述多个床旁医疗设备中与预设事件对应的床旁医疗设备发出第一信息。预设事件可以是系统设置的，也可以是用户设置的，例如，预设事件可以是用户通过人机交互装置输入的指令，预设事件可以是特定的时间点，预设时间可以是产生了特定的信息如产生了第一信息，等等。
步骤2、当床旁医疗系统的第二床旁医疗设备20对应预设事件时，第二床旁医疗设备20接收并响应第一信息。
由于各个床旁医疗设备得到了拓扑结构信息，任意两个床旁医疗设备之间就能针对性的互相通信。只需要将要发送的数据附加上目的床旁医疗设备的设备信息即可，即在需要传输的数据上标记要发给哪个床旁医疗设备，换而言之，第一信息包含目的床旁医疗设备的设备信息，则图2所示的方法还包括如下步骤：
若目的床旁医疗设备（例如第二床旁医疗设备20）与第一床旁医疗设备10相邻，则第一床旁医疗设备10发送第一信息，目的床旁医疗设备接收即可。
若第一床旁医疗设备10与目的床旁医疗设备之间存在一个或多个其他床旁医疗设备，则第一床旁医疗设备10、第一床旁医疗设备10与目的床旁医疗设备之间的各个床旁医疗设备均需要确定该用哪个通信连接来传输第一信息。
具体的，第一床旁医疗设备10若只有一个通信连接，则直接通过该通信连接发送第一信息即可，若有多个通信连接，则根据拓扑结构信息和目的床旁医疗设备的设备信息确定一通信连接，该确定的通信连接可达（间接的）目的床旁医疗设备，第一床旁医疗设备10通过该确定的通信连接发出第一信息。
由于第一床旁医疗设备10与目的床旁医疗设备之间的床旁医疗设备具有普适性，故取其中一个床旁医疗设备为例进行说明，假设其为第四床旁医疗设备40，则其发送第一信息的过程如图5所示，包括如下步骤：
步骤1.1、第四床旁医疗设备40通过第一通信连接接收第一信息，第四床旁医疗设备40为所述多个床旁医疗设备中的一个，第一通信连接为第四床旁医疗设备相邻的床旁医疗设备中的一个与第四床旁医疗设备40之间的通信连接（图1中第一通信连接为c）。
步骤1.2、第四床旁医疗设备40根据拓扑结构信息和目的床旁医疗设备的设备信息确定第二通信连接，第二通信连接为第四床旁医疗设备40相邻的设备中的一个与第四床旁医疗设备40之间的通信连接，所述拓扑结构信息记录有第四床旁医疗设备40可达的床旁医疗设备的设备信息和对应的通信连接的信息。
步骤1.3、第四床旁医疗设备40通过第二通信连接发送第一信息。由于每个床旁医疗设备在转发信息时，都会执行图5所示的流程，故信息的转发只需考虑与下一个床旁医疗设备之间的通信连接，跟其他床旁医疗设备的通信连接无关，从而使得整个床旁互联系统可以有多种多样的通信连接方式。新增的床旁医疗设备也无需考虑通信连接受限的问题，例如，需要新增的床旁医疗设备只有一种通信连接方式，只需要在系统中找到另外一个能匹配该通信连接的床旁医疗设备，即可将需要新增的床旁医疗设备加入到系统中，设备间的互联互通非常便利，适用场景广阔，可拓展出多种多样的应用。尤其是医院的各种床旁医疗设备通常是不同的厂家生产的，大多不兼容，而通过本发明提供的方法可实现通信上的互联互通，能快速、大规模的应用在当前各个医院、医疗机构中，应用前景广阔。
以图1为例，在第四床旁医疗设备40接收第一信息之前，第三床旁医疗设备30可同样根据图5所示的步骤转发第一信息给第四床旁医疗设备40。
若第二床旁医疗设备20为目的床旁医疗设备，则其接收第一信息并响应即可，例如，存储第一信息、显示第一信息、将第一信息与自身信息联合显示等，从而实现了各个设备间数据的共享和融合。
当然，目的床旁医疗设备也可以不止一个床旁医疗设备。例如，当第一信息的目的床旁医疗设备的设备信息为第二床旁医疗设备分组（包含至少两个床旁医疗设备）的设备信息时，第四床旁医疗设备40根据拓扑结构信息和第二床旁医疗设备分组的设备信息，确定第二床旁医疗设备分组中对应各床旁医疗设备的第三通信连接；进而通过各对应的第三通信连接发送第一信息。
又例如，当第一信息的目的床旁医疗设备的设备信息为至少两个床旁医疗设备的设备信息时，第四床旁医疗设备40根据拓扑结构信息和所述至少两个床旁医疗设备的设备信息确定所述至少两个床旁医疗设备中对应各床旁医疗设备的第三通信连接；进而通过各对应的第三通信连接发送第一信息。可见，实现了第一信息的多目的传播，通信过程方便快捷。
当然，任意一个床旁医疗设备都可以实现信息的广播。例如，当第一信息的目的床旁医疗设备的设备信息为预设床旁医疗设备的设备信息时，第四床旁医疗设备40通过所有与第四床旁医疗设备40相邻的床旁医疗设备之间的通信连接发送第一信息。换而言之，可以定义一个特殊的目的床旁医疗设备（预设床旁医疗设备）来表示这是需要发送到所有床旁医疗设备的。在步骤1.2中，床旁医疗设备判断应该把第一信息发送到哪个通信连接时，对于这个特殊的目的床旁医疗设备的设备信息，认为是需要发送到除接收第一信息的通信连接之外的所有通信连接，第一信息的传输路径如图6箭头所示。由此，实现了第一信息的广播，信息传输非常方便。
本实施例中，第一信息包括病人生理数据（如各种生理参数数据、对应的波形等）、病人信息、设备信息、设备状态和报警信息中的至少一种。病人信息包括但不限于：姓名、病历号、身高体重等。例如，床旁互联系统可为一个病人服务，若其中一个床旁医疗设备产生了病人生理数据、病人信息或报警信息等，则其他一个或所有床旁医疗设备都能得知，医护人员只需专心查看一个床旁医疗设备即可了解患者的整体情况，非常方便。又例如，当床旁互联系统中的一个床旁医疗设备获取到病人信息时，通过通信网络向床旁互联系统中的各床旁医疗设备发送病人信息。本实施例中，当病人信息为新增病人的病人信息或已有病人的更新病人信息时，通过通信网络向床旁互联系统中的各床旁医疗设备发送病人信息。即广播新的病人信息，如此，无需医护人员手动在各个设备中输入新的病人信息，减少了医护人员的工作量。
图2所示的数据处理方法，可应用于设备间的数据。本发明还可以可应用在数据订阅、获取上，对应的数据处理方法如图3所示，包括如下步骤：
步骤1’、第一床旁医疗设备10通过通信网络发出第一请求。由于第一床旁医疗设备10和第二床旁医疗设备20均为所述多个床旁医疗设备中的一个，两者在通信通路上可以是相邻的，也可以不相邻，本实施例以后者为例进行说明。将第一床旁医疗设备10和第二床旁医疗设备20之间的一个床旁医疗设备称之为第三床旁医疗设备30，则步骤1中，第一床旁医疗设备10通过通信网络和床旁互联系统中的第三床旁医疗设备30发出第一请求。图1中，由于通信通路上还有第四床旁医疗设备40，故第一床旁医疗设备10通过通信网络、第三床旁医疗设备30以及第四床旁医疗设备40发出第一请求。
第一床旁医疗设备10通过通信网络和床旁互联系统中的第三床旁医疗30设备发出第一请求，具体可以如图2实施例的第一信息那样，通过通信网络和第三床旁医疗设备30向第二床旁医疗设备20发送第一请求；也可以如图2实施例的第一信息那样，通过通信网络向床旁互联系统中的第一床旁医疗设备分组发送第一请求，第一床旁医疗设备分组包含至少两个床旁医疗设备；还可以如图2实施例的第一信息那样，通过通信网络广播第一请求。具体实时过程同图2实施例的第一信息，在此不做赘述。
步骤2’、当第二床旁医疗设备20通过通信网络接收到第一请求时，第二床旁医疗设备20确定自身是否满足第一请求，当第二床旁医疗设备20确定自身满足所述第一请求时，第二床旁医疗设备20通过通信网络响应第一请求。第一床旁医疗设备10可以以广播的形式发出第一请求，如图6所示，从而等待其他床旁医疗设备的响应。第一床旁医疗设备10若知晓第二床旁医疗设备20能满足第一请求，也可以将其作为目的床旁医疗设备，发送第一请求。第一请求从第一床旁医疗设备10传输到第二床旁医疗设备20的过程，可以同上述实施例中第一信息的传输过程，在此不做赘述。
本实施例中，第一请求为获取第二信息的请求，当第二床旁医疗设备20确定自身满足第一请求时，通过通信网络响应第一请求包括：当第二床旁医疗设备20确定与第一请求对应的第二信息可获取时，获取第二信息并通过通信网络发送给第一床旁医疗设备。第二信息可以由第二床旁医疗设备20生成，也可以由第二床旁医疗设备20从外部设备获取。
具体的，第二床旁医疗设备20发送第二信息时，可附带上其设备信息。从而，第一床旁医疗设备10记录第一请求和第二床旁医疗设备20的设备信息的对应关系。后续第一床旁医疗设备10有获取第二信息的请求时，直接向第二床旁医疗设备20发出第一请求即可，实现了数据的订阅。本实施例中，第二信息包括病人生理数据、病人信息、设备信息、设备状态和报警信息中的至少一种。可见，床旁医疗设备订阅其他床旁医疗设备的信息，本质上是将其他床旁医疗设备的能力为己所用，拓展了床旁医疗设备的功能。
当然，第二床旁医疗设备20也可以记录第一请求和第一床旁医疗设备的对应关系，当第二床旁医疗设备20获取到对应第一请求的第二信息时，将第二信息通过通信网络发送给第一床旁医疗设备。从而实现了数据的主动发送。第二床旁医疗设备20向第一床旁医疗设备10发送第二信息，其数据传输路径如图7所示，原理同第一请求的发送过程（将目的床旁医疗设备设置为第一床旁医疗设备即可），在此不做赘述。
可见，本发明通过统一的数据订阅发布机制，可实现第一信息、第二信息的自动、及时的同步，使系统中各个设备之间实现无障碍的、透明的（跟设备之间的通信连接方式、连接拓扑无关）数据共享，并能基于此实现各种融合的业务，例如：呼吸机在肺复张功能中，可以用监护仪共享的SpO2（血氧饱和度）值辅助进行判断；超声设备也可以用呼吸机的呼吸波形、监护仪的心电波形，进行辅助诊断。
本发明通过设备间的互联互通，还能实现能力共享。例如，通信能力的共享。例如第一请求为与外部通信的请求。当第二床旁医疗设备20确定满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求包括：当第二床旁医疗设备20确定自身具备外部通信的功能时，通过通信网络向第一床旁医疗设备10返回响应信息；第二床旁医疗设备20从而通过通信网络接收第一床旁医疗设备10发出的数据并向外部发送；第二床旁医疗设备20接收外部数据并通过通信网络发送给第一床旁医疗设备10，数据的传输如图8所示。可见，虽然第一床旁医疗设备10不具有与外部通信的能力，可借助第二床旁医疗设备20实现与外部的通信。当然，第二床旁医疗设备20也可以由用户指定，即用户指定第二床旁医疗设备20进行外部通信，则第二床旁医疗设备20通过通信网络接收第一床旁医疗设备10发出的数据并向外部发送；接收外部数据并通过通信网络发送给第一床旁医疗设备10。
第二床旁医疗设备20作为整个床旁互联系统的中转设备，与外部之间的通讯方式包括但不限于：有线网络，WIFI，蓝牙，4G\5G等通信方式。在病房中，床旁有多个设备，可能只有一个设备（如监护仪）能够联网（接入医院网络）。其他设备可通过串口、USB等有线方式，或者红外、蓝牙、WMTS等无线方式和该设备组成床旁互联系统，从而通过该设备进行中转通讯，打通和外界的联网通路，如此，实现了医院内各种医疗设备的联网。
除了通信能力的共享，还可以共享显示能力。例如，第一请求为显示数据的请求。当第二床旁医疗设备20确定满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求包括：当第二床旁医疗设备20确定自身具备显示功能时，通过通信网络向第一床旁医疗设备10返回响应信息；第二床旁医疗设备20通过通信网络接收第一床旁医疗设备10发送的待显示数据；第二床旁医疗设备20显示待显示数据，当然，也可以融合显示待显示数据和第二床旁医疗设备20自身数据。例如，监护仪将呼吸机、麻醉机中呼吸相关的治疗参数综合到主界面，与患者的生理参数数据一同显示，便于医护人员综合判断患者的状态、病因等。
本发明还可以共享打印能力，例如，第一请求为打印请求。当第二床旁医疗设备20确定满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求包括：当第二床旁医疗设备20确定自身具备打印功能时，通过通信网络向第一床旁医疗设备10返回响应信息；第二床旁医疗设备20通过通信网络接收第一床旁医疗设备10发送的待打印信息；第二床旁医疗设备20打印待打印信息。现有技术通常是所有设备都通过宽带连接打印机，而本发明床旁互联系统中的设备，可不受限于通信连接的方式，甚至不需要专门的打印机，利用具备打印功能的床旁医疗设备即可实现共享打印。
本发明还可以共享存储能力。例如，第一请求为存储请求。当第二床旁医疗设备20确定满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求包括：当第二床旁医疗设备20确定自身具备存储功能时，通过通信网络向第一床旁医疗设备10返回响应信息；第二床旁医疗设备20通过通信网络接收第一床旁医疗设备10发送的待存储数据；第二床旁医疗设备20存储待存储数据。
本发明还可以共享计算分析能力。例如，第一请求为数据计算分析请求。当第二床旁医疗设备20确定满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求包括：当第二床旁医疗设备20确定自身具备数据计算分析能力时，通过通信网络向第一床旁医疗设备10返回响应信息；第二床旁医疗设备20通过通信网络接收第一床旁医疗设备发送的待计算分析数据；第二床旁医疗设备20对待计算分析数据进行计算分析；第二床旁医疗设备20将计算分析结果通过通信网络发送给第一床旁医疗设备10。
图3所示的方法中，第一床旁医疗设备10发出第一请求后，第三床旁医疗设备30接收到第一请求时判断自身是否满足第一请求；当第三床旁医疗设备30判断自身满足第一请求时，第三床旁医疗设备30响应第一请求；当第三床旁医疗设备30判断自身不满足第一请求时，第三床旁医疗设备30通过通信网络转发第一请求。同样的，若第一床旁医疗设备10和第二床旁医疗设备20之间还有其他床旁医疗设备，如第四床旁医疗设备40，则同样执行本段中第三床旁医疗设备30的功能，在此不做赘述。
第二床旁医疗设备20接收第一请求，判断自身是否满足第一情况。当第二床旁医疗设备20确定自身不满足第一请求时，将第一请求转发至床旁互联系统中的下一床旁医疗设备，该下一床旁医疗设备为所述多个床旁医疗设备之中除第一床旁医疗设备10、第二床旁医疗设备20和第三床旁医疗设备30之外的设备。该下一床旁医疗设备接收第一请求；当该下一床旁医疗设备确定自身满足第一请求时，该下一床旁医疗设备通过通信网络响应第一请求；当该下一床旁医疗设备确定自身不满足第一请求时，该下一床旁医疗设备通过通信网络将第一请求转发至该下一床旁医疗设备的下一床旁医疗设备；当该下一床旁医疗设备确定自身不满足第一请求，且该下一床旁医疗设备为用于转发第一请求的转发路径的末设备时，说明系统中没有床旁医疗设备能满足第一请求，该下一床旁医疗设备通过通信网络向第一床旁医疗设备反馈用于指示第一请求无法满足的信息。
呼吸机，麻醉机、输注泵等设备有进行远程操作控制的需求，但是这种远程控制应用风险很高，需要确保控制命令是来自授权的可信设备，并且确保控制命令在传输过程中不会被篡改。通过设备配对机制，以及统一的授权和认证机制，可实现互联系统内部设备间安全可控的远程操作控制。
具体实现方案如图9所示，包括3部分内容：可靠的通信链路层93，安全的数据传输层92，安全的应用层91。上层利用下层提供的功能构建。其中，通信链路层93负责提供可靠的通信链路，对上层屏蔽具体通信连接方式的差异（例如串口、蓝牙、网络）；数据传输层92负责提供防嗅探截取、防数据伪造篡改、防数据包录制回放的安全数据传输。具体实现方式可以直接使用标准的SSL/TLS（“安全套接层”协议/“安全传输层”协议）。应用层91负责提供身份识别认证、权限管理和控制等安全应用。
床旁互联系统中，床旁医疗设备之间的通信是基于相邻两个床旁医疗设备的通信连接实现的。本实施例中，相邻的两个床旁医疗设备之间建立通信会话并随机生成通信会话密钥，需要传输信息时，通过通信会话密钥对信息进行加密，之后进行传输。以第一床旁医疗设备10和第三床旁医疗设备30为例，图1中两者相邻；第一床旁医疗设备10和第三床旁医疗设备30建立通信会话并随机生成通信会话密钥，第一床旁医疗设备10通过通信会话密钥对第一请求或第一信息加密后发送给第三床旁医疗设备30。具体的，过程如图10所示，包括：
第一床旁医疗设备10向第三床旁医疗设备30发出会话建立请求，其中会话建立请求包括随机的会话ID和第一床旁医疗设备10的身份标识。身份标识可以是设备信息，也可以是其他能唯一标识床旁医疗设备的标识。相邻两个设备之间的通信基于会话，每个会话有一个随机的会话ID，如此可以防止通信数据被录制回放。
第三床旁医疗设备30对第一床旁医疗设备10的身份标识进行校验。身份标识的编码规则和校验方式，由双方设备提前约定（例如写到代码中，或者在用户维护中设置）。为了防止数据是伪造的，通信会话建立的时候，先对对方的身份标识进行校验，校验通不过则直接终止会话。校验通过后，向第一床旁医疗设备10反馈会话应答，会话应答包括会话ID，第三床旁医疗设备的身份标识和第三床旁医疗设备的非对称加密算法的公钥。
第一床旁医疗设备10对第三床旁医疗设备30的身份标识进行校验，校验通过后，随机生成本次会话的对称加密密钥。第一床旁医疗设备10使用第三床旁医疗设备提供的非对称加密算法的公钥加密会话确认信息，会话确认信息包括会话ID和本次会话的对称加密密钥。
第三床旁医疗设备30用非对称加密算法的私钥解密，得到会话确认信息，即得到本次会话的对称加密密钥。之后两者之间的通信数据如第一信息、第一请求等，在加入会话ID后一同使用本次会话的对称加密密钥进行加密，之后通过通信连接进行传输。如此，数据在传输之前先进行加密，加密的密钥在会话建立的时候随机生成，避免通讯数据被嗅探。
上述图10的过程同样适用于床旁医疗设备与外部的通信，在此不做赘述。可见，设备之间及和外部系统之间进行通信时，需要进行身份识别和权限校验，确认对端是被合法授权的，而且数据在传输过程中是没有被篡改的，保证基于设备互联的业务是安全可控的。
要达到应用层的安全，防止对设备的未授权的控制，以及对隐私数据的未授权的访问，可以进行图11所示的操作。此部分关注的是任意的（不一定是相邻的）两个床旁医疗设备之间的应用业务交互安全。此部分的关键是识别出来对方是否是被授权的。一种方案是采用授权码，例如，第一请求或第一信息包括授权码。授权码由第二床旁医疗设备20基于用户的预设操作生成。第二床旁医疗设备20响应第一请求或第一信息，包括：第二床旁医疗设备20验证授权码，验证通过则响应第一请求或第一信息。具体过程如图11所示，包括：
用户在第二床旁医疗设备20进行预设操作，例如针对目标场景、目标时间段内、目标操作（例如控制、访问隐私数据），让第二床旁医疗设备20产生一个特定字符串，即授权码。
第二床旁医疗设备20根据用户的预设操作，生成所述授权码并自动记录下来和上述信息（目标场景、目标时间段内、目标操作）的绑定关系。
用户使用第一床旁医疗设备对第二床旁医疗设备进行控制或访问隐私数据时，将所述授权码输入到第一床旁医疗设备。
第一床旁医疗设备通过图10中的安全传输机制，把操作请求（包括目标场景、目标时间段内、目标操作等）和上述授权码一起发给第二床旁医疗设备。第一床旁医疗设备和第二床旁医疗设备可能不是相邻的设备，即可能经过了很多个设备中转，中转时同样可以采用图10的安全传输机制。
第二床旁医疗设备验证收到的该操作请求和授权码对应的目标场景、目标时间段、目标操作是否匹配，如果匹配则接受操作请求，否则拒绝；不论是接受还是拒绝，都返回一个结果给第一床旁医疗设备。所述的操作请求可以是控制床旁医疗设备执行各种功能的控制指令，也可以是上述的第一信息、第一请求等。
为了使各个设备之间的数据可以安全、正确地用于各种融合业务，可以在设备之间进行时间同步，使来自不同设备的数据在时间维度是对齐的。床旁互联系统中任意一个床旁医疗设备都可发起时间同步，为便于叙述，将发起时间同步的床旁医疗设备称之为第五床旁医疗设备，第五床旁医疗设备可以由用户指定，也可以由床旁互联系统按预设的规则协商确定。第五床旁医疗设备通过通信网络向床旁互联系统中的各床旁医疗设备发送特征信号，使接收到特征信号后的各床旁医疗设备根据特征信号与第五床旁医疗设备进行时钟同步。各床旁医疗设备接收到特征信号后进行时钟基准对齐。时钟基准对齐是指：所有设备都以该时刻为同一个时间点。该时间点可以为某个固定时间（例如0时间）；或者设备间协商好的时间（例如由发送特征信号的设备告诉其他设备）。
第五床旁医疗设备发送特征信号的时机可以是人工触发，或系统初始化的时候触发，或有新设备加入床旁互联系统的时候触发，或周期触发等。
第五床旁医疗设备通过通信网络向床旁互联系统中的各床旁医疗设备发送特征信号，例如可以采用如下方法：
第五床旁医疗设备通过通信网络向床旁互联系统中的各床旁医疗设备发送时延检测信号，并接收各床旁医疗设备基于时延检测信号的反馈信号。
如图12所示，第五床旁医疗设备根据发送时延检测信号的时刻t1以及各床旁医疗设备返回的反馈信号的时刻t2，计算各床旁医疗设备对应的传输时延。单次传输时延=t2-t1。为了更精确，可以多次执行本步骤，得到多个传输时延后取平均值。
第五床旁医疗设备可以按照各床旁医疗设备对应的传输时延分别以对应的时延向各床旁医疗设备发送特征信号，使各床旁医疗设备同时接收到特征信号。当然，第五床旁医疗设备也可以向各床旁医疗设备发送各自对应的传输时延，使各床旁医疗设备接收到特征信号后，根据传输时延完成与第五床旁医疗设备的时钟同步。
由于床旁互联系统中，每个床旁医疗设备都可能需要发起第一请求、发出第一信息，每个床旁医疗设备都可能能够响应对应床旁医疗设备发出的第一请求、第一信息，故上述各个床旁医疗设备提及的功能，大部分床旁医疗设备都可以具备，上述的第一床旁医疗设备、第二床旁医疗设备、第三床旁医疗设备、第四床旁医疗设备、第五床旁医疗设备等只是用于举例说明。
图13所示的床旁互联系统，同样包括多个床旁医疗设备，各个床旁医疗设备均通过床旁互联系统的通信网络通信。其中，床旁互联系统中有两个床旁医疗设备，为便于叙述，称之为第一床旁医疗设备10和第二床旁医疗设备20。第一床旁医疗设备10和第二床旁医疗设备20在拓扑结构上可以相邻也可以不相邻，图13只是用于示意。
第一床旁医疗设备10有需求时，可以通过通信网络发出第一请求。当第二床旁医疗设备20通过通信网络接收到第一请求时，第二床旁医疗设备20确定自身是否满足第一请求，当确定自身满足第一请求时，第二床旁医疗设备20通过通信网络响应第一请求。
当第二床旁医疗设备20确定自身不满足第一请求时，可以对第一请求进行转发，便于其他床旁医疗设备响应，为便于叙述，将其转发的床旁医疗设备称之为第三床旁医疗设备30。即，当第二床旁医疗设备20确定自身不满足第一请求时，第二床旁医疗设备20将第一请求转发至床旁互联系统中的第三床旁医疗设备30。第三床旁医疗设备可以是第二床旁医疗设备确定的满足第一请求的设备；第三床旁医疗设备也可以是第二床旁医疗设备确定的用于处理第一请求的设备。如此，无需第三床旁医疗设备判断也能收到第一请求，从而做出响应，非常适合第三床旁医疗设备计算处理能力不足甚至没有计算处理能力的场景。
当然，第三床旁医疗设备也可以如第二床旁医疗设备那样自行判断，具体的，第三床旁医疗设备接收第一请求，并判断自身是否满足第一请求，当第三床旁医疗设备确定自身满足第一请求时，通过通信网络向第一床旁医疗设备响应第一请求，或者通过通信网络和第二床旁医疗设备向第一床旁医疗设备响应第一请求。
当第三床旁医疗设备确定自身不满足第一请求时，第三床旁医疗设备可以通过通信网络将第一请求转发至所述多个床旁医疗设备中第三床旁医疗设备的下一床旁医疗设备。
当第三床旁医疗设备确定自身不满足第一请求，且第三床旁医疗设备为用于转发第一请求的转发路径的末设备时，第三床旁医疗设备通过通信网络向第一床旁医疗设备反馈用于指示第一请求无法满足的信息。第一请求包括用于获取第二信息、与外部通信、信息显示、信息打印、信息存储、信息计算分析之中至少一项的请求，这些能力上的共享，具体过程可以同上述实施例，在此不做赘述。
当然床旁互联系统中的床旁医疗设备还可以向其他床旁医疗设备发出各类信息。例如，当第一床旁医疗设备10触发预设事件时，第一床旁医疗设备10通过通信网络向所述多个床旁医疗设备中与预设事件对应的床旁医疗设备发出第一信息。当第二床旁医疗设备20对应预设事件时，第二床旁医疗设备20接收并响应第一信息。由于图13所示实施例中，床旁医疗设备的数据处理方法在原理上、细节上同图1所示的实施例，故在此不做赘述。
