具体实施方式
以下结合附图对本发明的具体实施方式进行详细说明。应当理解的是，此处所描述的具体实施方式仅用于说明和解释本发明，并不用于限制本发明。
图1是本发明一实施例提供的用于通气设备的控制系统的结构图，该通气设备具备多个工作模式。如图1所示，本发明提供的用于通气设备的控制系统可包括：识别装置10，用于识别所述通气设备的附件的类型；以及控制器20，用于根据所识别的所述附件的类型，确定并控制所述通气设备切换至与所述附件的类型相应的工作模式中。其中，所述附件可包括呼吸管路和/或患者界面，所述附件的类型可按照不同的机械连接特性、电气特性和/或气流特性进行划分；所述患者界面为面罩、吸氧管、鼻氧管、鼻导管或气切管。
在其他实施方式中，附件还可以是与通气设备主机相连通的水罐或加 湿器。
在通气设备上安装附件后，开启该通气设备，上述控制系统通过所识别的附件的类型将通气设备切换至与该附件的类型相应的工作模式，也就是说，安装附件后通过开启通气设备，该通气设备即可自动进入与所述附件的类型相应的工作模式中。另外，在通气状态下，更换通气设备的附件后，该控制系统通过所识别的通气设备的附件的类型切换至与所述附件的类型相应的工作模式，即该控制系统可自动切换工作模式，不需要通过手动切换相应的工作模式，减少了手动切换的错误操作几率，从而使得通气设备更加方便智能，进而节省医生和患者的大量时间。所述工作模式可包括压力模式及流量模式，这两种工作模式各自配备不同的附件的类型，例如，在压力模式下，主体部件30配备第一类附件(例如第一呼吸管路31及面罩32)，如图2(a)所示，以及在流量模式下，主体部件30配备第二类附件(例如第二呼吸管路33及鼻氧管34)，如图2(b)所示。其中所述第一呼吸管路31与第二呼吸管路33可以相同或者不同。处于所述压力模式下的通气设备是通过配备面罩进行治疗，通过给患者提供一定的吸气和呼气压力来维持气道开放，帮助患者呼吸、改善患者的通气量；而处于所述流量模式下的通气设备通过配备吸氧管、鼻氧管、鼻导管以及气切管中的任一者进行治疗，该通气设备输出的流量可以高于患者的最大吸气流量，以满足其吸入气量的需要。
处于不同工作模式下的通气设备所配备的附件的类型不同，所述识别装置还用于根据所述附件的机械连接特性、电气特性和/或气流特征识别该附件的类型。
接下来分别就以上三个方面对识别呼吸管路的类型进行详细地解释和说明：
第一种情形，可根据所述呼吸管路的机械连接特性的不同识别其类型。如图3所示，不同类型的呼吸管路的接头35与主体部件(用于输送患者呼 吸所需要的气体)的接头36的连接处的物理结构不同，例如，不同类型的呼吸管路的连接接头具有不同的插针或者弹片，当连接呼吸管路和主体部件时不同的插针或弹片会被压下，会产生不同的电信号。具体地，在第一类呼吸管路的连接接头上设置同种插针，其被压下时所产生的电信号为A，而在第二类呼吸管路的连接接头上设置同种弹片，其被压下时所产生的电信号为B，由此，在检测呼吸管路与主体部件连接时，若所产生的电信号为A，则可确定该呼吸管路为第一类呼吸管路；若所产生的电信号为B，则可确定该呼吸管路为第二类呼吸管路。在这种情况下，所述识别装置可包括：电信号接收器，用于接收所产生的电信号；以及分析器，用于根据所接收的电信号(例如电信号的强度和/或数目)确定所述呼吸管路的类型。
第二种情形，可根据所述呼吸管路的电气特性的不同识别其类型。具体地，首先根据不同类型的呼吸管路与主体部件之间的电气连接信号进行区分，若未检测到呼吸管路33与主体部件30之间的电气连接信号，则表明该类呼吸管路32为非加热管路，并确定其为第二类附件，如图4(a)所示；相应地，检测到呼吸管路31与主体部件30之间的电气连接信号，则表明该类呼吸管路为加热管路，并确定其为第一类附件，如图4(b)所示。若对于两类呼吸管路而言，均检测到呼吸管路与主体部件之间的电气连接信号，表明两类呼吸管路均为加热管路，则继续根据电气连接信号的具体情况区分两类附件，例如，所连接的导线数量、传感器类型、内部电路连接方式等具体情况，直至区分开两类呼吸管路为止。在这种情况下，所述识别装置可包括：电信号接收器，用于接收呼吸管路所产生的电信号；以及分析器，用于根据所接收的电信号来识别其类型。
第三种情形，可根据所述呼吸管路的气流特性的不同识别其类型。在两类呼吸管路具有不同的尺寸的情况下，通过不同尺寸的呼吸管路的气流所产生的阻力也不同。具体地，第一类呼吸管路的尺寸均相同且为A，第二类的尺寸均相同且为B(A>B)，由此，在检测通过呼吸管路的气流所产 生的阻力时，若所产生的阻力较小，则可确定该呼吸管路为第一类呼吸管路；若所产生的阻力较大，则可确定该呼吸管路为第二类呼吸管路。在这种情况下，所述识别装置可包括：阻力传感器，用于检测呼吸管路内气流的阻力；以及分析器，用于根据所检测的气流的阻力大小来识别其类型。
上述三种识别呼吸管路的类型的方式可以单独或联合使用，当然，本发明并不限于上述三种情形下所列出的具体识别方式，包括在机械连接特性、电气特性和/或气流特征在内的其他具体的识别方式也是可行的。另外，本发明也并不局限于根据与主体部件直接相连的呼吸管路的类型识别附件类型，也可以根据与主体部件间接相连的患者界面(例如面罩、鼻氧管等)识别附件类型。
所述控制系统还包括显示装置，用于显示所述通气设备的不同的工作模式。所述显示装置可为显示屏，可显示不同工作模式下不同的技术参数，也可在通气设备故障时，显示故障代码，便于维护人员进行检修。
所述控制器可以是通用处理器、专用处理器、常规处理器、数字信号处理器(DSP)、多个微处理器、与DSP核心关联的一个或多个微处理器、控制器、微控制器、专用集成电路(ASIC)、现场可编程门阵列(FPGA)电路、其他任何类型的集成电路(IC)、状态机等等。
具体而言，如图5所示，控制通气设备自动切换至两种工作模式的过程包括如下步骤：
步骤S501，判断所述附件的类型，在该附件的类型为第一类型的情况下，执行步骤S502；在该附件的类型为第二类型的情况下，执行步骤S503。
步骤S502，控制通气设备切换至压力模式。
切换至压力模式后，操作者可进行与压力模式相关的参数设置。
步骤S503，控制通气设备切换至流量模式。
切换至流量模式后，操作者可进行与流量模式相关的参数设置。
当然，通气设备可设置不同的多种工作模式，所述工作模式包括持续 正压模式、自动正压模式、双水平正压模式，高流量模式以及低流量模式等模式中的至少两者。在上述的多种工作模式下，主体部件也配备不同类型的附件，于是可采用两种工作模式下识别不同附件的类型的方式，即根据所述附件的机械连接特性、电气特性和/或气流特征识别该附件的类型(于此不再赘述相关识别内容)；并根据所识别的附件类型控制所述通气设备切换至与附件匹配的工作模式中。由此，可使通气设备切换实现更加全面的功能，更加智能化，节省操作者的时间。
具体而言，如图6所示，控制通气设备自动切换至多种工作模式的过程包括如下步骤：
步骤S601，判断所述附件的类型，在该附件的类型为第一类型的情况下，执行步骤S602；在该附件的类型为第二类型的情况下，执行步骤S603；在该附件的类型为第三类型的情况下，执行步骤S604；以及……
步骤S602，控制通气设备切换至第一工作模式。
步骤S603，控制通气设备切换至第二工作模式。
步骤S604，控制通气设备切换至第三工作模式。
……
当然，对于第一工作模式、第二工作模式、第三工作模式……等工作模式而言，其是不同的工作模式。针对通气治疗设备来说，第一工作模式可以为持续正压模式、第二工作模式可以为高流量模式、第三工作模式为自动正压模式。
在另一实施方式中，通过识别装置识别附件的类型，可根据附件的类型进入到对应的工作模式下相应的工作状态，其中，所述工作状态与该工作模式下的参数设置相关。参数包括压力、流量、升压时间等。具体地，当通气治疗设备为多个患者使用，通气治疗设备中存储有多个患者的对应的治疗模式，每个治疗模式下对应有患者的参数设置。如第一患者对应于持续正压模式下的A参数设置，第二患者对应于持续正压模式下的B参数 设置，第三患者对应于高流量模式下的C参数设置。当第一患者使用与其适配的附件的类型时，将附件连接至通气治疗设备时，通气治疗设备可直接进入到持续正压模式下的A参数设置。通过设置不同的压力和/或升压时间等参数将持续正压模式细分为不同的参数设置，以更有针对性地服务于不同的患者，从而提高患者的满意度。
在优选实施例中，所述附件还可配置有存储单元，该存储单元内存储有该附件的编号，所述控制器还用于，根据所述附件的类型及该附件的编号，确定并控制所述通气设备切换至与所述附件的类型相应的工作模式中的相应的工作状态，其中，所述工作状态与所述编号相对应，其中，所述工作状态与该工作模式下的参数设置相关，例如，可按照所设置的不同的压力和/或升压时间等参数将持续正压模式细分为不同的工作状态；所述附件的编号可与患者的身份标签ID一一对应，优选地，所述附件的编号可为所述患者ID。
具体地，以所述附件为带有芯片的加热管路为例进行说明，该加热管路的芯片内存储有编号(如患者ID，该患者ID可为患者身份证号、患者姓名等)。在使用通气设备之前，提前将所述加热管路的编号(如患者ID)及其在与所述加热管路的类型相对应的工作模式中的工作状态之间的对应关系存储在控制器内。当所述加热管路插入通气设备时，所述控制器首先根据所述加热管路的类型，控制通气设备切换至对应的工作模式，然后再根据加热管路的芯片内所存储的编号，控制通气设备切换至该工作模式中对应的工作状态下。或者，当所述加热管路插入通气设备时，所述控制器根据所述加热管路的类型及加热管路的芯片内所存储的编号，控制通气设备直接切换至对应的工作模式中对应的工作状态下。由此，所述通气设备可以更有针对性地服务于不同的患者，从而提高患者的满意度。此外，本发明还可以通过手动方式(例如按键、旋钮或触屏等)来切换不同的工作模式，设置这种手动切换方式的意义在于，在一些不连接附件的场合下，医 生仅仅想查看某一工作模式下的界面信息或者患者的使用数据，可以通过该手动切换方式切换至目标模式进行查看。
综上所述，本发明创造性地通过所识别的通气设备的附件的类型来自动切换相应的工作模式，不需要通过手动切换相应的工作模式，减少了手动切换的错误操作几率，从而使得通气设备更加方便智能，进而节省医生和患者的大量时间。
相应地，如图7所示，本发明还提供一种用于通气设备的控制方法，该控制方法可包括以下步骤：步骤S701，识别所述通气设备的附件的类型；以及步骤S702，根据所识别的所述附件的类型，确定并控制所述通气设备切换至与所述附件的类型相应的工作模式中。
有关本发明提供的用于通气设备的控制方法的具体细节及益处可参阅上述针对用于通气设备的控制系统的描述，于此不再赘述。
相应地，本发明还提供一种通气设备，该通气设备可包括：主体部件，用于输送患者呼吸所需要的气体；附件，用于配合所述主体部件完成所述气体的输送；以及根据上述的用于通气设备的控制系统。
相应地，本发明还提供一种机器可读存储介质，所述机器可读存储介质上存储有指令，该指令用于使得机器执行所述的用于通气设备的控制方法。
所述机器可读存储介质包括但不限于相变内存(相变随机存取存储器的简称，Phase Change Random Access Memory，PRAM，亦称为RCM/PCRAM)、静态随机存取存储器(SRAM)、动态随机存取存储器(DRAM)、其他类型的随机存取存储器(RAM)、只读存储器(ROM)、电可擦除可编程只读存储器(EEPROM)、快闪记忆体(Flash Memory)或其他内存技术、只读光盘只读存储器(CD-ROM)、数字多功能光盘(DVD)或其他光学存储、磁盒式磁带，磁带磁盘存储或其他磁性存储设备等各种可以存储程序代码的介质。
以上结合附图详细描述了本发明的优选实施方式，但是，本发明并不限于上述实施方式中的具体细节，在本发明的技术构思范围内，可以对本发明的技术方案进行多种简单变型，这些简单变型均属于本发明的保护范围。
另外需要说明的是，在上述具体实施方式中所描述的各个具体技术特征，在不矛盾的情况下，可以通过任何合适的方式进行组合。为了避免不必要的重复，本发明对各种可能的组合方式不再另行说明。
此外，本发明的各种不同的实施方式之间也可以进行任意组合，只要其不违背本发明的思想，其同样应当视为本发明所公开的内容。
