可以理解的是，通气配件10可以经管路连接至呼吸机，以及通过连接鼻塞、面罩、或鼻罩等与患者接触的患者接口，实现呼吸机与患者通气。即通气配件10可以是患者与呼吸机的通气连接结构。
目前新生儿尤其是早产儿由于肺功能不足或其他呼吸疾病，往往需要进行呼吸支持。呼吸支持的方式包括无创通气及有创通气。为了尽量减少有创机械通气的并发症同时又可以有效治疗呼吸疾病，临床医生倾向于早期优先应用无创通气，根据无创通气支持效果决定是否给予有创机械通气。在新生儿重症监护病房中经常会采用经鼻无创通气，进行呼吸支持、治疗，达到促进氧合和有效排出二氧化碳等效果，常用的通气方式有NCPAP(Nasal Continuous Positive Airway Pressure，无创持续正压通气)，NIPPV(Non Invasive Positive Pressure Ventilation，无创间歇正压通气)，BiPAP(Bi-level Positive Airway Pressure，双水平正压气道通气)等。因为连接简便，并能有效降低呼气做功，在新生儿无创通气中应用十分广泛。本申请提供的通气配件10可以应用于无创通气呼吸机，实现对患者无创通气。

在一个实施例中，呼吸连接部20与管路连接部30固定连接。呼吸连接部20与管路连接部30可以是一体设置。通气配件端口21对患者进行呼气通气和吸气通气。管路连接部30设置两个通气管路端口39，两个通气管路端口39分别为呼气管路端口34和吸气管路端口36。呼气管路端口34可以经通气配件端口21与患者呼气通气，吸气管路端口34也可以经通气配件端口21与患者吸气通气。通气配件端口21与呼气管路端口34及吸气管路端口36可以经气体通道连通。吸气管路端口36可以经管路连接至呼吸机，通气配件端口21可以经气体通道、吸气管路端口36和管路与呼吸机连通。当然，作为一种改进方式，管路连接部30也可以是设置一个通气管路端口39，通气管路端口39与呼气管路和吸气管路连接。
另一个实施例中，如图2所示，与图1所示实施例不同的是，呼吸连接部20与管路连接部30转动连接。呼吸连接部20设有转动轴201，管路连接部30设有转轴孔301。转动轴201插入转轴孔301，并与转轴孔301转动配合。转动轴201的端部周侧壁设有转动凸 缘2011。转轴孔301的内周侧壁设有与转动凸缘2011配合的转动凹槽3011。转动凸缘2011的外径较小，通过转动轴201插入转轴孔301，转动凸缘2011卡入转动凹槽3011后，管路连接部30可相对呼吸连接部20转动，且管路连接部30不易脱离呼吸连接部20。通气配件端口21和第一采样端口22设置于呼吸连接部20远离转动轴201处。第一采样连接端口31和通气管路端口39设置于管路连接部30远离转轴孔301处。
具体的，第一采样端口22与转动轴201同轴设置。转轴孔301底部设有与通气配件端口21对接的通气对接孔312，以及设有与第一采样端口22对接的采样对接孔3013。通气对接孔3012与通气管路端口39连通，采样对接孔3013与第一采样连接端口31连通。采样对接孔3013与转轴孔301同轴设置，通气对接孔312为设置于采样对接孔3012周侧的环形孔，以方便呼吸连接部20与管路连接部30在转动情况下，仍保证通气配件端口21与通气管路端口39连通，以及第一采样端口22与第一采样连接端口31连通。
在另一个实施例中，如图3所示，与图1所示实施例不同的是，呼吸连接部20与管路连接部30可伸缩地连接。具体的，呼吸连接部20设有滑动轴202。管路连接部30设有滑动轴孔302。滑动轴202可插入滑动轴孔302内，并可沿滑动轴孔302的深度方向相对管路连接部30滑动，实现呼吸连接部20相对管路连接部30伸缩。管路连接部30还设有与滑动轴孔302连通的滑动限位槽303。滑动限位槽303的延伸方向与滑动轴孔302的深度方向相平行。呼吸连接部20在滑动轴202的外侧壁设有限位凸块203。限位凸台203在滑动限位槽303内滑动，以对滑动轴202相对管路连接部30滑动限位，防止呼吸连接部20与管路连接部30脱离。通气配件端口21和第一采样端口22设置于呼吸连接部20远离滑动轴202处。第一采样连接端口31和通气管路端口39设置于管路连接部30远离滑动轴孔302处。
为保证第一采样连接端口31与第一采样端口22的气密性，以及保证通气管路端口39与通气配件端口21的气密性。管路连接部30在滑动轴孔302内设置通气滑动管路3021和采样滑动管路3022，通气滑动管路3021可以与通气配件端口21滑动对接。采样滑动管路3022可以与第一采样端口22滑动对接。通气滑动管路3021远离通气配件端口21一端与通气管路端口39连通。采样滑动管路3022远离第一采样端口22一端与第一采样连接端口31连通。
另一个实施例中，如图4所示，与图1所示实施例不同的是，呼吸连接部20设有两个通气配件端口21，一个是接收患者呼出气体的呼气端口211，另一个是向患者提供吸气气体的吸气端口212，第一采样端口22设置于呼气端口211内。呼气端口211与呼气管路端口34连通，吸气端口212与吸气管路端口36连通。当呼气端口211对患者呼气通气时，吸气端口212处于不通气状态。当吸气端口212对患者吸气通气时，呼气端口211处于不通气状态。当然，作为一种改进方式，第一采样端口22也可以是与呼气端口211分离设置，并靠近呼气端口211。作为一种改进方式，第一采样端口22也可以是设置于吸气端口212内，或者是与吸气端口212分离设置，并靠近吸气端口212。
请继续参阅图1，本实施方式中，第一采样端口22为二氧化碳采样端口，第一采样端口22可以采集患者呼出或吸入的二氧化碳气体。第一采样连接端口31可以经管路与二氧化碳监测设备连接，使得第一采样端口22经第一采样连接端口31及管路连接至二氧化碳 监测设备，使得二氧化碳监测设备可以获取患者呼出或将吸入的二氧化碳气体，以实现对患者呼出或将吸入的二氧化碳的浓度进行监测。第一采样端口22可以设置于通气配件端口21内，也可以与通气配件端口21分离设置，还可以是部分与通气配件端口21分离，部分与通气配件端口21重合。
当然，在其他实施方式中，第一采样端口22也可以是氧气采样端口，第一采样连接端口31为氧气监测连接端口，第一采样连接端口31可以经管路与氧气监测设备连接，以使得氧气监测设备可以获取患者呼出或将吸入的氧气气体，以实现对患者呼出或将吸入的氧气的浓度进行监测。
当然，第一采样端口22还可以是压力采样端口，第一采样连接端口31可以经管路与监测设备的压力传感器连接，实现对患者呼吸气路中的气压进行监测。也就是说，本申请的第一采样端口22所获取的采样监测的气体并不作限定，以及采样监测方式不作限定。
可以理解的是，在无创通气过程中，对于患者的二氧化碳水平进行监测非常重要，以防止出现高碳酸血症等症状。现有新生儿无创通气过程中的二氧化碳水平评估，主要依靠采取患者的血气，以分析其中的二氧化碳分压。但是采血气会带来患儿的不适、疼痛和感染的风险，而且因为新生儿血量很少，周期性的采血甚至会带来贫血症和其它危害。因此，采用本实施方式提供的通气配件10采集患儿呼出气体，以进行二氧化碳水平评估，有助于减少医疗危害。
本实施方式中，第一采样端口22设置于通气配件10的呼吸连接部20，可以距离通气配件端口21较近。
具体的，由于通气配件10的呼吸连接部20可以与鼻塞、面罩、或鼻罩等与患者接触的患者接口直接连接，使得通气配件10的呼吸连接部20近患者。第一采样端口22可以靠近通气配件端口21设置，或设置于通气配件端口21内。第一采样端口22可以与通气配件端口21一同连接至鼻塞、面罩、或鼻罩等与患者接触的患者接口。通气配件端口21离患者鼻或口较近，可以缩短第一采样端口22与患者鼻或口的距离，以方便第一采样端口22在靠近患者鼻或口的位置处对患者呼出或将吸入的气体进行采样。由于第一采样端口22处于患者呼吸通气气路的近鼻端或近口端的位置，可以减小通气气路中基础流对患者呼出气体的影响，采样气体可以更真实地反应患者呼出气体的浓度、湿度、温度等参数。例如，第一采样端口21可以在近患者鼻端或近患者口端的位置，采集患者将呼出的二氧化碳气体，并通过二氧化碳监测设备与第一采样连接端口31对接，实现二氧化碳监测设备可以准确测量患者呼出的二氧化碳浓度，通过监测设备可以监测出二氧化碳浓度值和变化趋势来反映患者的新陈代谢、血气分压、肺泡通气功能和参数，支持医护人员进行诊断。可以理解的是，二氧化碳浓度分析仪可以与呼吸机通讯数据连接或者集成到呼吸机上，呼吸机可以将二氧化碳浓度监测值和二氧化碳波形图在屏幕上显示出来。

请参阅图5，在另一个实施例中，与图1所示实施例不同的是，通气通道23内设有内置管路232，内置管路232与通气通道23同轴设置。内置管路232的外周侧壁与通气通道23的内周侧壁存在间距。内置管路232延伸方向与通气通道23的延伸方向一致。第一采样端口22开设于内置管路232远离通气通道23底部的一端。第一采样进气通道24开设于内置管路232内。第一采样进气通道24与通气通道23同轴设置，使得第一采样进气通道24传输气体速度更快，增加监测响应速度，以及提高监测准确性。
