在本实施例中，呼吸回路302还可以包括用于检测气道压力的压力测量模块3023，在具体实现时，压力测量模块3023可以是压力传感器，压力测量模块3023设置于吸气支路3021或呼气支路3022。呼吸回路302还可以包括设置于呼气支路3022的流速测量模块3024，在本实施例中，呼气支路3022包括压力测量模块3023和流速测量模块3024至少之一。
在图3中，压力测量模块3023设置在吸气支路3021，流速测量模块3024设置在呼气支路3022，当然也可以是在吸气支路3021和呼气支路3022中各设置有一个压力测量模块3023，呼气支路3022中还设置有流速测量模块3024，从而可以测量通过呼气支路3022的气体流速。
处理模块304，在呼气阀开启和关闭情况下，根据压力测量模块3023检测到的患者吸气支路3021或呼气支路3022的压力变化和/或流速测量模块3024检测到的呼气支路3022的流速变化，确定通气设备当前所处的氧疗模式为双管氧疗模式或单管氧疗模式。
当通气设备当前所处的氧疗模式为双管氧疗模式时，控制呼气阀关闭、吸气阀开启，通过吸气支路3021输出富氧气体。
当通气设备当前所处的氧疗模式为单管氧疗模式时，通过吸气支路3021输出富氧气体。
在双管氧疗过程中，通气控制模块303在压力测量模块3023检测到的呼气支路3022的第三压力大于第一压力阈值时，开启呼气阀，并保持呼气支路3022中的压力小于或者等于第一压力阈值。
这里，在开启呼气阀之后，间隔一定时长后，通气控制模块303在压力测量模块3023检测到的呼气支路3022的第四压力小于第三压力阈值时，关闭呼气阀，持续通过吸气支路3021向患者输出富氧气体。
在本实施例中，第三压力阈值不能大于第一压力阈值，也就是说第三压力阈值是可以小于或者等于第一压力阈值的。
通气设备还包括报警模块和输出模块，输出模块可以包括语音播放器、显示屏等，输出模块可以用于输出显示通气设备当前所处的氧疗模式。在氧疗过程中，报警模块在压力测量模块3023检测到的呼气支路的第三压力大于第二压力阈值时，向输出模块发送报警信息。输出模块可以在接收到报警模块发送的报警信息后，向用户报警。其中，第二压力阈值是不小于第一压力阈值的，也即第二压力阈值是大于或者等于第一压力阈值的。
在本实施例中，通气设备当前所处的氧疗模式和报警信息可以是以音频的形式输出，还可以是以图像的形式输出。也就是说，可以通过语音播报通气设备当前所处的氧疗模式和报警信息，也可以是在显示屏上显示通气设备当前所处的氧疗模式和报警信息。
在本实施例中，处理模块304在确定通气设备当前所处的氧疗模式为双管氧疗模式还是单管氧疗模式时，可以是仅通过吸气支路3021或呼气支路3022的压力变化来确定，还可以是仅通过呼气支路3022的流速变化来确定，还可以是通过压力变化和流速变化共同来确定。
当仅通过吸气支路3021或呼气支路3022的压力变化来确定氧疗模式 时，处理模块304先获取呼气阀开启时，压力测量模块3023检测到的吸气支路3021或呼气支路3022的第一压力；再获取呼气阀关闭时，压力测量模块3023检测到的吸气支路3021或呼气支路3022的第二压力；如果第一压力与第二压力之间的第一变化量满足第一预设条件，处理器304确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第一变化量不满足第一预设条件，处理器304确定通气设备当前所处的氧疗模式为单管氧疗模式。
在实际应用中，第一变化量可以是指第二压力与第一压力的第一差值，第一预设条件可以是第一差值大于预设的第一差值阈值；第一变化量还可以是由第一压力变化至第二压力的第一变化速率，第一预设条件可以是第一变化速率大于预设的第一变化率阈值。
当仅通过流速变化来确定氧疗模式时，处理模块304获取呼气阀开启时，流速测量模块3024检测到的呼气支路3022的第一流速，并获取呼气阀关闭时，流速测量模块3024检测到的呼气支路3022的第二流速；如果第一流速与第二流速之间的第二变化量满足第二预设条件，处理器304确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第二变化量不满足第二预设条件，处理器304确定通气设备当前所处的氧疗模式为单管氧疗模式。
在实际应用中，第二变化量可以是指第一流速与第二流速的第二差值，第二预设条件可以是第二差值大于预设的第二差值阈值；第二变化量还可以是由第一流速变化至第二流速的第二变化速率，第二预设条件可以是第二变化速率大于第二变化率阈值。
当通过压力变化和流速变化共同来确定氧疗模式时，首先获取呼气阀开启时，压力测量模块3023检测到的吸气支路3021或呼气支路3022的第一压力和流速测量模块3024检测到的呼气支路3022的第一流速；再获取呼气阀关闭时，压力测量模块3023检测到的吸气支路3021或呼气支路3022 的第二压力和流速测量模块3024检测到的呼气支路3022的第二流速；如果第一压力与第二压力之间的第一变化量满足第一预设条件，或第一流速与第二流速之间的第二变化量满足第二预设条件，处理器304确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第一压力与第二压力之间的第一变化量不满足第一预设条件，且第一流速与第二流速之间的第二变化量不满足第二预设条件，处理器304确定通气设备当前所处的氧疗模式为单管氧疗模式。
需要说明的是，第一压力和第二压力对应的支路是相同的，例如，若第一压力是压力测量模块3023检测到的吸气支路3021的压力，那么第二压力是测量模块检测到的吸气支路3021的压力；若第一压力是压力测量模块3023检测到的呼气支路3022的压力，那么第二压力是测量模块检测到的呼气支路3022的压力。
本实施例提供的通气设备300至少包括驱动模块301、呼吸回路302、通气控制模块303和处理模块304；其中，通气控制模块301，控制驱动模块302通过呼吸回路302向患者提供通气支持；呼吸回路302包括吸气支路3021和呼气支路3022；吸气支路3021设置有吸气阀，呼气支路3022设置有呼气阀；呼吸回路302还包括用于检测气道压力的压力测量模块3023和设置于呼气支路的流速测量模块3024；处理模块304在呼气阀开启和关闭情况下，根据压力测量模块3023检测到的压力变化，和/或流速测量模块3024检测到的流速变化，确定通气设备当前所处的氧疗模式为双管氧疗模式或单管氧疗模式；当通气设备当前所处的氧疗模式为双管氧疗模式时，控制呼气阀关闭、吸气阀开启，通过吸气支路3021输出富氧气体；当通气设备当前所处的氧疗模式为单管氧疗模式时，通过吸气支路3021输出富氧气体；如此，不仅可以自动确定通气设备当前所处的氧疗模式，还能够不进行管路的更换即可实现双管氧疗，从而能够减少医护人员的操作，并降 低病人的感染风险和更换管路的费用。另外，通气控制模块303在压力测量模块3023检测到的呼气支路3021的压力大于第一压力阈值时，开启呼气阀，并保持患者气道压力小于或者等于第一压力阈值，这样能够防止病人端堵塞导致压力过高，而对病人造成伤害，进而提高通气设备的安全性。
本申请实施例提供一种通气设备的控制方法，应用于通气设备，该通气设备至少包括：接收模块、驱动模块、呼吸回路和通气控制模块。图4为本申请实施例通气设备的控制方法的实现流程示意图，如图4所示，该方法包括以下步骤：
步骤S401，接收模块接收开启氧疗模式指令。
这里，在本实施例中，该通气设备可以是呼吸机。该通气设备中的呼气回路包括呼气支路和吸气支路，其中呼气支路至少包括呼气阀，吸气支路至少包括吸气阀。
步骤S401在实现时，开启氧疗模式的指令可以是通过按压或者触控开启氧疗模式的按键而触发生成的，还可以是通过预设的语音或者手势而触发生成的。因此，接收模块可以是按键、触摸屏、语音接收装置、图像接收装置等设备。
步骤S402，当接收到的开启氧疗模式指令为开启双管氧疗模式时，通气控制模块控制呼气阀关闭，控制吸气阀开启，以控制驱动模块通过吸气支路输出富氧气体。
这里，在其他实施例中，在接收到开启氧疗模式指令之后，还需要根据通气设备的氧疗参数来确定通气设备当前所处的氧疗模式，并且在通气设备当前所处的为双管氧疗模式时，确定接收到的开启氧疗模式指令为开启双管氧疗模式的指令；在通气设备当前所处的为单管氧疗模式时，确定接收到的开启氧疗模式指令为开启单管氧疗模式的指令。
当接收到的开启氧疗模式指令为开启双管氧疗模式时，可以通过通气 控制模块将呼气阀的封阀压力设置为预设值，以实现控制呼气阀关闭；通过通气控制模块将吸气阀的封阀压力设置为零，以实现控制吸气阀开启，并通过吸气支路输出富氧气体。
在本实施例提供的通气设备的控制方法中，首先接收模块接收开启氧疗模式指令，当接收到的开启氧疗模式指令为开启双管氧疗模式时，通气控制模块控制通气设备的呼气阀关闭，控制通气设备的吸气阀开启，以通过吸气支路输出富氧气体，如此，通气设备在接收到开启双管氧疗模式的指令时，控制呼气阀关闭，能够不进行管路的更换即可实现双管氧疗，从而能够减少医护人员的操作，并降低病人的感染风险和更换管路的费用。
基于前述实施例，本申请实施例再提供一种通气设备的控制方法，应用于其他实施例提供的通气设备，该通气设备至少包括：接收模块、驱动模块、呼吸回路、处理模块和通气控制模块。图5为本申请实施例通气设备的控制方法的又一实现流程示意图，如图5所示，方法包括以下步骤：
步骤S501，接收模块接收开启氧疗模式指令。
步骤S502，基于开启氧疗模式指令，通气控制模块控制通气设备的呼气阀开启，处理模块获取通气设备的第一氧疗参数。
这里，在实际应用中，可以通过通气控制模块将呼气阀的封阀压力设置为零，以实现控制呼气阀开启。第一氧疗参数可以包括吸气支路或呼气支路的第一压力，还可以包括呼气支路的第一流速。
步骤S503，通气控制模块控制通气设备的呼气阀关闭，处理模块获取通气设备的第二氧疗参数。
这里，在实际应用中，可以是通气控制模块将呼气阀的封阀压力置为预设值，以实现呼气阀关闭。第二氧疗参数可以包括吸气支路或呼气支路的第二压力，还可以包括呼气支路的第二流速。
步骤S504，处理模块根据第一氧疗参数和第二氧疗参数确定通气设备 当前所处的氧疗模式。
这里，步骤S504至少可以通过以下三种实现方式实现：
第一种实现方式：处理模块根据吸气支路或呼气支路的压力变化确定通气设备当前所处的氧疗模式，其中，如果第一压力与第二压力之间的第一变化量满足第一预设条件，处理模块确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第一变化量不满足第一预设条件，处理模块确定通气设备当前所处的氧疗模式为单管氧疗模式。
第二种实现方式：处理模块通过呼气支路的流速变化确定通气设备当前所处的氧疗模式，其中，如果第一流速与第二流速之间的第二变化量满足第二预设条件，处理模块确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第二变化量不满足第二预设条件，处理模块确定通气设备当前所处的氧疗模式为单管氧疗模式。
第三种实现方式：处理模块通过压力变化和流速变化确定通气设备当前所处的氧疗模式，其中，如果第一压力与第二压力之间的第一变化量满足第一预设条件，或第一流速与第二流速之间的第二变化量满足第二预设条件，处理模块确定通气设备当前所处的氧疗模式为双管氧疗模式；如果第一变化量不满足第一预设条件，且第二变化量不满足第二预设条件，处理模块确定通气设备当前所处的氧疗模式为单管氧疗模式。
在其他实施例中，处理模块在确定出当前所处的氧疗模式后，还会由通气设备的输出模块输出通气设备当前所处的氧疗模式，以便于医护人员和患者能及时了解通气设备的氧疗模式。
步骤S505，处理模块判断通气设备是否处于双管氧疗模式。
这里，如果通气设备处于双管氧疗模式时，进入步骤S507；如果通气设备处于单管氧疗模式时，进入步骤S506。
步骤S506，通气控制模块控制驱动模块通过吸气支路输出富氧气体。
步骤S507，通气控制模块控制通气设备的呼气阀关闭。
步骤S508，通气控制模块控制通气设备的吸气阀开启，以控制驱动模块通过吸气支路输出富氧气体。
需要说明的是，本实施例中与其它实施例中相同步骤或概念的解释可以参考其它实施例中的描述。
步骤S509，处理模块获取通气设备中呼气支路当前的第三压力。
这里，第三压力可以是实时获取的，还可以是每间隔一定时长获取一次，例如可以是每间隔5秒获取一次。
步骤S510，处理模块判断第三压力是否大于第一压力阈值。
这里，如果第三压力大于第一压力阈值，说明通气设备呼气支路的压力过大，容易对病人造成危害，此时进入步骤S512，通过开启呼气阀进行泄压；如果第三压力不大于第一压力阈值，则说明通气设备中呼气支路的压力不易对病人造成危害，此时进入步骤S511。
步骤S511，通气控制模块保持呼气阀关闭，并循环进入步骤S509。
步骤S512，通气控制模块控制呼气阀开启，以保持通气设备的压力小于或者等于第一压力阈值。
步骤S513，处理模块获取通气设备中呼气支路当前的第四压力。
这里，第四压力可以是实时获取的，还可以是每间隔一定时长获取一次，例如可以是每间隔5秒获取一次。
步骤S514，处理模块判断第四压力是否小于第三压力阈值。
这里，如果第四压力小于第三压力阈值，说明通气设备呼气支路的当前压力较小，可以再次对呼气阀进行封阀，以防止富氧气体从呼气支路中泄露出去，此时进入步骤S507；如果第四压力不小于第三压力阈值，说明通气设备呼气支路的当前压力依然较大，此时进入步骤S515，保持呼气阀开启，以避免因为气道压力过大对患者造成危害。
步骤S515，通气控制模块保持呼气阀开启，并循环进入步骤S513。
在其他实施例中，在步骤S508之后，方法还包括：如果第三压力大于第二压力阈值，输出报警信息，以提示用户通气设备呼气支路的压力过大，极易对病人造成危害，需要暂停使用该通气设备。
在本实施例提供的通气设备的控制方法中，首先当检测到开启氧疗模式的操作指令时，控制通气设备的呼气阀开启，获取通气设备的第一氧疗参数；然后控制通气设备的呼气阀关闭，获取通气设备的第二氧疗参数；根据第一氧疗参数和第二氧疗参数确定通气设备当前所处的氧疗模式为双管氧疗模式或单管氧疗模式在通气设备处于双管氧疗模式时，控制通气设备的呼气阀关闭；控制通气设备的吸气阀开启，以通过吸气支路输出富氧气体，在通气设备处于单管氧疗时，直接通过吸气支路输出富氧；如此，通气设备自身可以确定当前所处的氧疗模式，并进行相关氧疗模式的送气操作，从而能够减少医护人员的操作，并降低病人的感染风险和更换管路的费用；并在双管氧疗模式下获取自身当前的第三压力，当第三压力大于第一压力阈值时，开启呼气阀，进行泄压，以防止病人端因呼气阀关闭导致压力过高，对病人造成伤害。
本申请实施例再提供一种通气设备的控制方法，图6为本申请实施例通气设备的控制方法的再一实现流程示意图，如图6所示，该方法包括以下步骤：
步骤S601，氧疗模式打开后，通气设备开始送气。
步骤S602，控制通气设备的呼气阀按照设定压力进行封阀。
这里，该设定压力可以是通气设备在出厂时就默认设置好的，还可以是用户手动设置的。
步骤S603，在通气设备进行氧疗通气时，实时监测呼气支路的第三压力，判断呼气支路的第三压力是否大于第一压力阈值。
这里，如果第三压力大于第一压力阈值，说明呼气支路中压力过大，容易对病人造成危害，此时进入步骤S604；如果第三压力小于或者等于第一压力阈值，且通气设备处于报警状态，此时进入步骤S606。
步骤S604，控制呼气阀打开，进行泄压并且保持呼气支路中的压力不超过第一压力阈值。
这里，在其他实施例中，在步骤S604之后，会根据实时监测到呼气支路的当前压力，判断是否再次将呼气阀进行封阀，在实际应用过程中，可以是通过判断呼气支路的当前压力是否小于第三阈值，其中，当呼气支路的当前压力小于第三阈值时，可以再次将呼气阀进行封阀。
步骤S605，报警提示用户气道阻塞。
步骤S606，清除报警状态。
这里，报警阈值可以等于第一压力阈值。在其他实施例中，报警阈值还可以是大于第一压力阈值的，报警阈值可以是通气设备在出厂时就默认设置好的或者用户手动设置的，当第三压力低于报警阈值时，报警取消。
在本实施例中，在步骤S602“控制通气设备的呼气阀按照设定压力进行封阀”之前，通气设备的控制方法还包括单双管氧疗模式的识别过程，图7为本申请实施例单双管氧疗模式的识别过程的实现流程示意图，如图7所示，过程包括：
步骤S701，通气设备开启氧疗功能，开始送气。
步骤S702，打开呼气阀。
步骤S703，测量当前的呼气流速Fexp1和呼气压力Pexp1。
步骤S704，关闭呼气阀。
步骤S705，测量当前的呼气流速Fexp2和呼气压力Pexp2。
步骤S706，判断是否满足Pexp2-Pexp1小于第一差值阈值且Fexp1-Fexp2小于第二差值阈值。
这里，如果Pexp2-Pexp1小于第一差值阈值且Fexp1-Fexp2小于第二差值阈值，那么此时进入步骤S708；如果Pexp2-Pexp1不小于第一差值阈值或Fexp1-Fexp2不小于第二差值阈值，此时进入步骤S707。
第一差值阈值和第二差值阈值可以是由用户预先设置好的，还可以是通气设备在出厂时默认设置好的。例如，第一差值阈值可以是1厘米水(cmH2O)，第二差值阈值可以是1升每分钟(Liter Per Minute，LPM)。
步骤S707，确定通气设备当前所处的为双管氧疗模式。
步骤S708，确定通气设备当前所处的为单管氧疗模式。
在其他实施例中，在确定了通气设备的氧疗模式后，还可以输出显示通气设备当前所处的氧疗模式，并进行相关管路类型的送气操作。
需要说明的是，在其他实施例中，还可以单独采用呼气压力或者呼气流速来确定通气设备当前所处的氧疗模式，识别单双管路类型，并进行单双管对应的氧疗送气，而且在双管氧疗模式时，通过关闭呼气阀来防止富氧气体从呼气管泄露，并实时检测呼气支路中的压力，在呼气支路的压力大于第一压力阈值时，则将呼气阀开启进行泄压，从而避免因气道压力过高给病人带来危害，提高了设备的安全性。

  16. 根据权利要求11至14中任一项所述的方法，其特征在于，在如果所述通气设备当前所处的氧疗模式为双管氧疗模式，所述通气控制模块控制所述通气设备的呼气阀关闭之后，所述方法还包括：
    所述处理模块获取所述通气设备当前的第三压力；
    如果所述第三压力大于第一压力阈值，所述通气控制模块控制所述呼气阀开启，以保持所述通气设备的呼气支路的压力小于或者等于所述第一压力阈值。
  17. 根据权利要求16所述的方法，所述通气设备还包括报警模块和输出模块，其特征在于，所述方法还包括：
    当所述压力测量模块检测到的呼气支路的第三压力大于第二压力阈值时，所述报警模块向所述输出模块发送报警信息；
    所述输出模块在接收到报警模块发送的报警信息后，输出报警信息。
  18. 根据权利要求11至15中任一项所述的方法，其特征在于，所述方法还包括：
    所述输出模块输出所述通气设备当前所处的氧疗模式。
  19. 根据权利要求11中所述的方法，其特征在于，所述方法还包括：
    在接收到的开启氧疗模式指令为开启单管氧疗模式时，所述通气控制模块通过吸气支路向患者输出富氧气体。
  20. 一种计算机存储介质，其特征在于，所述计算机存储介质中存储有通气设备的控制程序，所述通气设备的控制程序被处理器执行时实现权利要求11至19中任一项所述的通气设备的控制方法的步骤。
