根据本发明中发热单元320的一种实施方式，发热单元320可包括发热体321，发热体321设置在第一风机出气口3112与中转壳出气口3313的连通通路上。
其中，发热体321可以理解为是一种通电后能够发热从而实现气体加热的元件。例如发热体321可以是由铁铬铝合金、镍铬合金或者铜丝等材质制成的元件。发热体321可以具有任意适当的形状，例如片状(如图4所示)、丝状(即发热丝)等。
发热单元320加热得到的高温消毒气体的温度优选为不低于60℃，进一步优选为 70-85℃。
进一步地，为了便于发热体321的安装，发热单元320还可包括安装筒322，安装筒322的一端密封连接于第一风机出气口3112，安装筒322的另一端密封连接于中转壳进气口3312，发热体321安装于安装筒322内(参见图5和图6)。当然，在其他实施方式中，发热体321可直接安装在中转壳进气口3312或者外壳出气口3123处。发热体321也可采用其他方式安装在第一风机出气口3112与中转壳出气口3313的连通通路上。
另外，发热单元320还可包括单向阀323，以保证气体按照从第一风机出气口3112至中转壳进气口3312的方向单向流动。单向阀323可安装于安装筒322内。本发明通过将发热体321、单向阀323、安装筒322集成一体，能够便于安装、维护以及与其他结构的配合。
为了使得消毒装置300结构紧凑，布局合理，占用空间小，如图6所示，也可将发热单元320安装于外壳312的安装腔3121内，安装筒322的上端与外壳出气口3123对应连通，并与中转壳进气口3312连通。
需要说明的是，本发明中各个进气口、出气口之间的连通均为密封连通，以防止气体泄漏，保证气体供应的高效性，同时利于对气体的控制。
本发明中，消毒装置300还可包括第一气体监测器333，第一气体监测器333可设置于中转腔3311内用于监测高温消毒气体的属性，即温度、湿度、压力、流量、流速等。
第一气体监测器333可以安装于中转腔3311内的任意位置，第一气体监测器333也可以为多个，例如可以分别在中转腔3311的进气口和出气口处设置第一气体监测器333，以监测进入气体和排出气体的属性。
本发明中，消毒装置300还可包括控制单元，第一气体监测器333可将监测的信息传递至控制单元，控制单元可根据第一气体监测器333监测的信息控制发热体321和第一风机311的运行，实现对高温消毒气体属性的控制。
本发明的消毒装置300可以有两种工作模式，分别为消毒模式和冷却模式。
具体地，当开启消毒模式时，第一风机311运行向发热单元320提供气体，控制单元控制发热体321发热对来自第一风机311的气体进行加热以形成高温消毒气体，接着高温消毒气体经单向阀323进入中转腔3311内，然后经中转壳出气口3313进入待消毒设备中对待消毒设备的气道进行高温消毒。
当切换至冷却模式时，运行方式同消毒模式，但是控制单元控制发热体321不发 热，使得来自第一风机311的常温气体直接进入中转腔3311内，进而进入待消毒设备的气道中，快速带走气道中的热量给整个气道降温，方便患者及时使用待消毒设备。
待消毒设备与中转壳出气口3313连接的接口可视为待消毒设备的进气口，待消毒设备气道的另一端可视为出气口。在实际使用时，最好在待消毒设备的出气口处设置限流件，比如流量阀，以控制输出流量，避免流量过大而失去消毒的效果。
本发明另一方面提供一种通气治疗设备，包括上述消毒装置300，消毒装置300用于将高温消毒气体通至通气治疗设备的气道中。
具体地，所述通气治疗设备可包括主机100和消毒装置300。其中，主机100用于产生治疗气体，主机100具有主机进气口111和主机出气口112；消毒装置300用于产生高温消毒气体，消毒装置300与主机进气口111或主机出气口112连通，以用于向主机100和湿化器200中通入高温消毒气体。
进一步地，所述通气治疗设备还可包括湿化器200，湿化器200用于对治疗气体加湿，湿化器200具有湿化器进气口211和湿化器出气口212，湿化器进气口211与主机出气口112连通。消毒装置300可与湿化器200连通，以用于向湿化器200中通入高温消毒气体。
上述中，可以理解的是，消毒装置300与主机100和湿化器200的连通可以有三种情况，第一种：消毒装置300与主机100连通，具体为与主机进气口111连通，消毒装置300位于主机100侧，主机出气口112与湿化器进气口211直接连通；第二种：消毒装置300与湿化器200连通，具体为与湿化器出气口212连通，消毒装置300位于湿化器200侧，主机出气口112与湿化器进气口211直接连通(参见图15)；第三种：消毒装置300与主机100和湿化器200连通，具体为与主机出气口112和湿化器进气口211连通，也就是说，消毒装置300设置于主机100和湿化器200之间，主机出气口112和湿化器进气口211通过消毒装置300间接连通(参见图9、图11、图13或图14)。
在上述第一种和第二种情况下，消毒装置300可具有一个中转壳出气口3313(参见图15)；在上述第三种情况下，消毒装置300可具有两个中转壳出气口3313，两个中转壳出气口3313分别与主机出气口112和湿化器进气口211连通(参见图13或图14)。
本发明中，参见图12，主机100可包括具有空腔113的主机壳110和设置于空腔113内的第二动力单元，主机进气口111和主机出气口112设置在主机壳110上并与空腔113连通。
其中，参见图13，第二动力单元可包括第二风机120，第二风机120具有第二风 机进气口121和第二风机出气口122，第二风机进气口121与主机进气口111对应连通，第二风机出气口122与主机出气口112对应连通。
在使用时，第二风机120可将主机进气口111外的气体依次经主机进气口111和第二风机进气口121吸入第二风机120内，并将所述气体依次经第二风机出气口122和主机出气口112排出主机100外。
本发明中，主机100还可包括主机接头150，主机接头150可以设置在主机壳110上，主机接头150可与外部电源电连接，以向第二风机120供电。消毒装置300的电源接头313可与主机接头150连接，以由主机接头150供电(参见图13)。
本发明中，主机100还可包括过滤件130，过滤件130安装于主机进气口111处。过滤件130可用于过滤进入主机100的气体，避免灰尘、杂质、颗粒物等进入主机100内污染主机100，并最终进入患者呼吸道。
由于第二风机120在使用过程中会在第二风机进气口121处形成负压，为了防止过滤件130在负压作用下进入第二风机120内，可在主机进气口111处设置限位结构对过滤件130进行限位。具体地，例如图12和图13所示，所述限位结构可以是设置于主机进气口111内侧的止挡件140，止挡件140上设置有供气体通过的通孔。
本发明中，参见图12和图13，湿化器200包括具有湿化腔213的湿化器壳体210，湿化器进气口211和湿化器出气口212设置在湿化器壳体210上并与湿化腔213连通。
上述中，湿化腔213内可储存有液体，例如水，以对气体进行加湿。为了增加气体在湿化腔213内的过水面积，从而提高湿化率，可在湿化腔213内设置能够引导气体以较长流动路径流动的引导结构。具体地，例如图12-图15所示，所述引导结构可以是引导板220，经湿化器进气口211进入湿化腔213内的气体可先沿引导板220向下流动，然后再向上流动至湿化器出气口212排出。
本发明中，通气治疗设备还可包括控制单元，该控制单元可以是消毒装置300的控制单元，该控制单元设置为能够控制第一动力单元310、第二动力单元以及发热单元320的运行。也就是说，所述控制单元用于控制整个通气治疗设备的运行。
本发明中，通气治疗设备还可包括限流单元400，限流单元400可设置在主机进气口111和/或湿化器出气口212处。
具体地，在消毒装置300与主机进气口111连通时，限流单元400可设置在湿化器出气口212处，以用于限制湿化器出气口212处的气流量；在消毒装置300与湿化器出气口212连通时，限流单元400可设置在主机进气口111处，以用于限制主机进气口111 处的气流量(参见图15)；在消毒装置300连通于主机出气口112与湿化器进气口211之间时，限流单元400可以有两个，并分别设置在主机进气口111和湿化器出气口212处，以用于分别限制主机进气口111和湿化器出气口212处的气流量(参见图11)。
其中，限流单元400可包括限流件410，限流件410设置为能够与主机进气口111或湿化器出气口212连接，以限制经主机进气口111或湿化器出气口212排出的高温消毒气体的气流量，避免流量过大，失去消毒的效果。限流件410可具有多种实施方式，例如，限流件410可以是流量阀，也可以是如图11和图12所示的筒状结构，该筒状结构的一端可以与主机进气口111或湿化器出气口212插接，另一端则具有端壁，端壁上开设有多个通气孔。
当然在其他实施方式中，通气治疗设备可不单独设置限流单元400，而是利用主机或湿化器自身结构产生的较大气阻来实现限流的功能。
为了防止经主机进气口111或湿化器出气口212排出的高温消毒气体对使用者造成烫伤、灼伤等伤害，限流单元400可包括防护件420，防护件420设置为能够与主机进气口111或湿化器出气口212连接。当然，在限流件410采用如图11和图12所示的实施方式的情况下，防护件420可安装于限流件410外。
具体地，如图11和图12所示，防护件420可包括防护筒421，防护筒421套设于限流件410外。
进一步地，为了防止手指进入防护筒421或者其他物体进入防护筒421使防护筒421发生堵塞，防护筒421的背离限流件410的一端可设置有拦截格栅422。
本发明中，通气治疗设备还可包括第二气体监测器430，第二气体监测器430可用于监测经主机进气口111或湿化器出气口212排出的高温消毒气体的属性，以便于更好的控制消毒装置运行。
本发明中，通气治疗设备还可包括通气管路和患者接口装置，通气管路的一端连接于患者接口装置，通气管路的另一端可以连接于湿化器出气口212或者中转壳出气口3313。
本发明的通气治疗设备可以有三种工作模式，分别为治疗模式、消毒模式以及冷却模式。
具体地，以图14为例，当开启治疗模式时，第一风机311和单向阀323为关闭状态，第二风机120运行，如图14中箭头所示，气体依次经主机进气口111和第二风机进气口121进入第二风机120内，然后依次经第二风机出气口122、主机出气口112、 左侧中转壳出气口3313进入中转腔3311内，之后依次经右侧中转壳出气口3313、湿化器进气口211进入湿化腔213内进行湿化，湿化后气体经湿化器出气口212进入通气管路中，最后进入患者接口装置供患者吸入。
当开启消毒模式时，参见图13所示的实施方式，第二风机120为关闭状态，开启第一风机311和单向阀323，发热体321发热，如图13中箭头所示，气体经第一风机进气口3111进入第一风机311内，然后经第一风机出气口3113进入安装筒322内，经发热件321加热形成的高温消毒气体依次经单向阀323、中转壳进气口3312进入中转腔3311内，然后分别经左右两侧的中转壳出气口3313进入第二风机120和湿化腔213内，对主机100和湿化器200进行高温消毒后，经主机进气口111和湿化器出气口212排出。当然，湿化器出气口212连接有通气管路和患者接口装置时，也可进一步对通气管路和患者接口装置进行高温消毒。
当开启消毒模式时，参见图15所示的实施方式，第二风机120为关闭状态，开启第一风机311和单向阀323，发热体321发热，如图15中箭头所示，气体经第一风机进气口3111进入第一风机311内，然后经第一风机出气口3113进入安装筒322内，经发热件321加热形成的高温消毒气体依次经单向阀323、中转壳进气口3312进入中转腔3311内，然后依次经中转壳出气口3313、湿化器出气口212进入湿化腔213内对湿化器200进行高温消毒后，之后，高温消毒气体依次经湿化器进气口211、主机出气口112、第二风机出气口122进入第二风机120内，对主机100进行高温消毒后依次经第二风机进气口121、主机进气口111排出。
当开启冷却模式时，发热体321不发热，第一风机311或第二风机120运行，将外界的常温气体吸入通气治疗设备内部，快速带走设备内的热量，给整个设备降温。
在实际使用时，可将通气治疗设备设置为只有当湿化器出气口212连接限流单元400时，控制单元才开启消毒模式，这样可以防止未安装限流单元400的湿化器出气口212对空或者连接通气管路，而对使用者或者患者造成烫伤、灼伤等伤害。
通过上述技术方案，从通气治疗设备的进气口一直到通气治疗设备的出气口，患者呼吸的气体经过通气治疗设备内部的所有气道都可以通过消毒装置的高温消毒气体进行全方位的消毒，消毒无死角，无残留，能够彻底解决患者使用通气治疗设备时内部存在病菌的风险问题。
本发明中，所述通气治疗设备可以是呼吸机、氧疗仪等。
本发明中，参见图16，所述通气治疗设备还可包括消毒管路500，消毒管路500 的两端可分别与主机100和消毒装置300可拆卸连接并连通，以与主机100和消毒装置300一起形成供高温消毒气体循环流动的通道。
其中，需要说明的是，消毒管路500与主机100和消毒装置300的连接可以是直接连接，也可以是间接连接。例如在图16所示的实施方式中，消毒管路500的两端分别与主机100和消毒装置300直接可拆卸连接，具体为与主机进气口111和中转壳出气口3313连接；例如在图9所示的实施方式中，消毒管路500的两端分别与主机100和湿化器200直接可拆卸连接(具体为与主机进气口111和湿化器出气口212连接)，与消毒装置300为间接连接。
另外，为了提高高温消毒气体在整个通道内温度的均匀性，保证消毒效果，还可以在主机100内设置发热单元320，如图16所示。
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。
