【具体实施方式】
下面通过具体实施例结合附图对本发明作进一步详细说明。
本申请提供的气体处理装置通过一体化气路板中特定的气路引导气体的走向，实现对被测气体的实时采集和/或自然连通，从而对气体进行至少两种形式的处理，例如根据具体需要，处理方式可以包括对被测气体进行浓度监测、力学参数监测和/或负压处理等。该气体处理装置能够简化气路结构，有效减少通过软胶管联结气路的环节且方便操作。
一种实施例中，气体处理装置包括至少一个第一气体监测模块、至少一个第二气体监测模块、主控模块、以及一体化气路板。主控模块分别耦合到第一气体监测模块和第二气体监测模块，对第一气体监测模块和第二气体监测模块进行控制。一体化气路板表面开设排气口、至少一个进气口和至少一个监测接口，内部开设第一气路和至少一条第二气路；其中，进气口包括第一进气口和第二进气口，第一气路为具有气体进出口的通路，第一进气口与排气口分别与第一气路的两端连通而形成贯通的气体通道，第一气路通过至少一个监测接口对应地连通到第一气体监测模块，待测气体在气泵的作用下从第一进气口流入第一气路后，经第一气体监测模块检测后再从排气口流出，使第一气路可实时地采集被测气体。第二气路为只有一端连通的盲路，第二进气口与第二气路的一端连通，第二气路通过至少一个监测接口连通到第二气体监测模块,待测气体从第二进气口自然流入第二气路后直接被第二气体检测模块监测，使第二气路中的气体不与外界气体连通且不受外部气流的干扰。
一种实施方式中，气体处理装置主体为层状结构，气体处理装置包括层叠的线路板和一体化气路板，线路板位于一体化气路板开设有监测接口的一面，主控模块安装在线路板上，线路板还可同时集成供电电路、信号处理电路、信号采样传感模块等组成部分实现系统供电、信号采集、数据计算和输出等，线路板与一体化气路板层叠式安装，使设备结构更加紧凑，从而减少设备体积和功耗。一体化气路板或线路板上还可固定一些气体处理模块或其他器件，例如传感器、氧浓度监测模块、三通阀等，以便进一步减小设备实现多功能测试时的总体积。每个气体监测模块都包括信号接口和气路接口，其信号接口与主控模块信号连接且能与主控模块进行通讯，信号接口与主控模块之间可以是有线连接或无线连接，通过有线或无线的通讯方式在信号接口与主控模块之间实现信息交互。气路接口与一体化气路板中对应的监测接口密封连接以便对气体进行相应的处理。
另一种实施例中，气体处理装置包括多个第一监测模块和一体化气路板，一体化气路板表面开设排气口、第一进气口和多个监测接口，内部设有第一气路，第一气路为具有气体进出口的通路，第一进气口与排气口分别与第一气路的两端连通而形成贯通的气体通道，第一气路通过对应的监测接口将多个第一气体监测模块串联连通, 待测气体在气泵的作用下从第一进气口流入第一气路后，依次经过多个第一气体监测模块检测后再从排气口流出。
以上实施例中，一体化气路板可采用金属或塑胶制成的板形件，例如将具有凹槽的两块板通过超声焊接、激光焊或粘合的方式固接而制成一体化气路板，两块板上的位置对应的凹槽合拢而形成气路；当然还可在两块板之间填充密封材料而形成气路。
请参考图1至图3的实施例，气体处理装置用在医疗设备中，用于对病人呼吸回路中的气体进行处理，例如监测气体浓度、监测呼吸力学参数等，根据具体需要，还可对气体进行负压处理后输出负压气体以供其他设备使用。具体地，第一气体监测模块包括氧浓度监测模块和麻醉气体以及二氧化碳气体浓度监测模块，分别用于监测氧浓度、麻醉气体和CO2浓度，当然在其他实施例中，第一气体监测模块还可为用于监测其他类型气体浓度的气体浓度监测模块，以及用于监测气体的其他特性的气体监测模块。第二监测模块为呼吸力学监测模块，包括表压传感器和压差传感器，分别用于监测气体表压和气体差压。例如通过测量气道内几个点气体的压力，获得气道压力、气道流量和时间三个基本参数，再通过计算获得如潮气量、吸气呼气时间比 （ I:E rate ） 、 呼气末端正向压力 （ PEEP Pressure ） 等参数，用来衡量病人气道通气状况。当然在其他实施例中，第二气体监测模块还可为用于监测气体的其他特性的气体监测模块。
在有些实施例中，在监测气体浓度的过程中还可利用压差传感器检测气路压差，通过气路压差计算气体流量，以便将气体流量反馈给系统进行气体流量控制。
本实施例的一体化气路板1为注塑成型的金属或塑胶板，端部并排设置多个进气口和一个排气口，表面开设用于连接各气体监测模块的监测接口以及用于连接三通阀6和气泵单元等器件的其他接口，内部设置气容、气路限流器以及多条气路，为了实现气路密封，各气体监测模块的气路接口与一体化气路板1表面对应的监测接口通过密封圈5密封连接。线路板2上的主控模块是整个系统的核心控制部件，其与各监测模块及三通阀6信号连接，线路板2上还集成了与主控模块信号连接的硬件供电电路、信号处理电路、信号采样传感模块等。本实施例中，为了节省空间，线路板2上还通过焊接、粘结等方式固定了表压传感器3、差压传感器4和三个用于校零的三通阀6，这些器件的管脚都与主控模块的相应管脚焊接。三通阀6还通过端面的自带密封圈9与一体化气路板1上对应的接口密封连接，压板7压在并排设置的三个三通阀6上，螺钉8穿过压板7将线路板2与一体化气路板1固定为一体，使整个装置的结构更加紧凑和小巧。
在有些实施例中，三通阀6的数量、安装位置都可灵活设置，例如使三通阀6的数量与一起化气路板1内部的气路数量相同。
请参考图3和图4，一体化气路板1端部的进气口包括负压进气口43d、第一进气口44d、校零进气口45d和两个第二进气口46d、47d，进入负压进气口43d、第一进气口44d、校零进气口45d的气体都需要在气泵的作用下，在相应的气路中流动后从排气口48d流出。
一体化气路板1中的气路主要包括第一气路、第二气路、第三气路和校零气路。其中，第一气路为采样气路，用于实现对病人呼吸回路中的气体进行浓度监测，需要对病人呼吸回路中的气体进行实时采集，因此第一气路为气流通路，与其进出口分别和一体化气路板1上的第一进气口44d和排气口48d连通。如图4中带有箭头的虚线所示的气路，其通过对应的监测接口将麻醉气体以及二氧化碳气体浓度监测模块和氧浓度监测模块串联在第一气路中，用于供麻醉气体以及二氧化碳气体浓度监测模块和氧浓度监测模块依次提取一定样气后，分别进行相应的气体浓度监测。麻醉气体以及二氧化碳气体浓度监测模块的气路接口为一组GMB探头，在一体化气路板1表面对应的监测接口包括GMB进气口12a和GMB出气口11a。氧浓度监测模块可根据体积大小选择使用内置氧浓度监测模块或外置氧浓度监测模块，在一体化气路板1表面对应的监测接口可包括用于连接外置氧浓度监测模块的外置进气接口41d和外置出气接口42d、以及用于连接内置氧浓度监测模块的内置进气接口32c和内置出气接口31c，外置进气接口41d与外置出气接口42d之间或者内置进气接口32c和内置出气接口31c之间选择性地采用气体管道连通。其中，外置进气接口41d和外置出气接口42d可与一体化气路板1的多个进气口和排气口48d并排设置，以便减少设备体积且便于气路连接。在有些实施例中，第一气路通过对应的监测接口还可将多个用于对气体进行其他方式的监测的第一气体监测模块串联连通，这些第一气体监测模块中的一个或者多个也可包括外置第一气体监测模块或内置第一气体监测模块，并采用以上实施例的方式选择连接在外置进气接口41d与外置出气接口42d之间或者内置进气接口32c与内置出气接口31c之间。
第二气路包括两条独立的呼吸力学气路，如图4中虚线所示与采样气路隔离。对病人呼吸回路进行呼吸力学参数监测时，需要模拟呼吸回路中的气流状况，以便检测压力和压差。本实施例中，第二气路为只有一个进气端的盲路，与呼吸回路自然连通，不受外界的气流干扰，也不会形成额外的气流扰动。在一体化气路板1表面与呼吸力学气路连通的监测接口包括表压传感器接口61f和两个压差传感器接口，表压传感器接口61f连通其中一条呼吸力学气路，表压传感器3紧贴表压传感器接口61f，且其气路接口与表压传感器接口61f密封连通，压差传感器接口包括第一压差采集口62f和第二压差采集口63f，第一压差采集口62f和第二压差采集口63f分别连通两条呼吸力学气路，差压传感器4紧贴两个压差传感器接口，且其气路接口与两个压差传感器接口密封连通。在有些实施例中，第二气路还可具有三条以上且相互独立，分别通过对应的监测接口连接到多个用于对气体进行其他方式的监测的第二气体监测模块。
第三气路为负压气路，其中设有负压气路限流器55e，负压气路将负压进气口43d与排气口48d连通，用于对气体进行负压处理后输出负压气体以供其他设备使用，本实施例的负压气路可采样气路部分共用。
气体处理装置还可包括气泵单元，采样气路中还包括用于稳定气泵单元出气口气压的第一气容54e和第二气容57e，气泵单元可连接在两个气容之间以实现抽气功能,负压气路可与采样气路共用这两个气容及气泵单元。本实施例具有两个并联的气泵单元，两个气泵单元分别可包含一个或者多个气泵，都用于将气体从第一气容54e中抽至第二气容57e中，二者抽取的气体能够形成互补气流从而进一步稳定气流。本实施方式中，第一气泵单元与一体化气路板1表面的第一组气泵接口21b、22b连接，第二气泵单元与一体化气路板1表面的第二组气泵接口23b、24b连接。当然根据具体需要，第一气容54e和第二气容57e之间还可连接一个或者两个以上的气泵单元。
校零气路如图4中箭头所示，为只有一端连通的盲路。每个三通阀6都具有校零端、第一连接端和第二连接端，第一连接端与第二连接端之间处于常通状态，校零端在校零状态下与第二连接端连通。一体化气路板6表面开设至少一个校零接口，一体化气路板6的进气口还包括校零进气口45d，校零气路的进气端与校零进气口45d连通，校零气路通过至少一个校零接口分别连通到各三通阀6的校零端，并根据主控模块1的指令，通过三通阀6可控地与采样气路中连通麻醉气体以及二氧化碳气体浓度监测模块和氧浓度监测模块的部分连通，或与呼吸力学气路中连通表压传感器3或压差传感器4的部分连通。校零过程中，标准气体从校零进气口45d进入采样气路或呼吸力学气路从而对相应的气体监测模块进行校零，以提高气体监测的准确性。
本实施例包括一条采样器和两条呼吸力学气路，因此一体化气路板1上的校零气路具有三个校零接口。采样气路和每条呼吸力学气路都按照气流方向分隔成前段和后段，麻醉气体以及二氧化碳气体浓度监测模块和氧浓度监测模块都连接在第一气路的后段，表压传感器3或压差传感器4都连接在呼吸力学气路的后段，一体化气路板1表面还开设有分别连通到前段和后段的第一三通阀接口和第二三通阀接口，即采样气路或呼吸力学气路的前段各连通一个第一三通阀接口，后段各连通一个第二三通阀接口，同一气路中两个三通阀接口的位置相邻。将三通阀6与采样气路或呼吸力学气路进行气路连接时，对应气路的校零接口、第一三通阀接口和第二三通阀接口连通到各三通阀6的校零端、第一连接端和第二连接端。本实施例中，每条气路上用于连接同一三通阀6的校零接口、第一三通阀接口和第二三通阀接口都排列在同一直线上，一体化气路板2还可紧贴三通阀6，且使各校零接口、第一三通阀接口和第二三通阀接口分别对准三通阀6的校零端、第一连接端和第二连接端，使气路结构更加紧凑，能够进一步减少设备体积。
具体地，采样气路中，第一三通阀接口79g和第二三通阀接口78g分别连接在第一个三通阀的第一连接端和第二连接端而处于常通状态，需要校零时，该三通阀6控制第一三通阀接口79g与第二三通阀接口78g之间断开，并控制其校零端77g与第二三通阀接口78g连通而使校零气路与采样气路连通。第一条呼吸力学气路中，第一三通阀接口76g与第二三通阀接口75g分别连接在第二个三通阀的第一连接端和第二连接端而处于常通状态，需要校零时，该三通阀6控制第一三通阀接口76g与第二三通阀接口75g之间断开，并控制其校零端74g与第二三通阀接口75g连通而使较零气路与第一条呼吸力学气路连通。同样地，第二条呼吸力学气路中，第一三通阀接口73g与第二三通阀接口72g分别连接在第三个三通阀的第一连接端和第二连接端而处于常通状态，需要校零时，该三通阀6控制第一三通阀接口73g与第二三通阀接口72g之间断开，并控制其校零端71g与第二三通阀接口72g连通而使较零气路与第二条呼吸力学气路连通。
本实施例中，采样气路中的气体流动顺序为:
第一进气口44d（或校零过程中采用较零进气口45d）—>三通阀6—>通过GMB进气口12a和GMB出气口11a进入 GMB探头—> 通过内置进气接口32c和内置出气接口31c进入内置氧浓度监测模块（或通过外置进气接口41d和外置出气接口42d进入外置氧浓度监测模块）—> 采样气路限流器53e及差压传感器51e、52e—> 第一气容54e—> 通过第一气泵单元接口21b、22b进入第一气泵单元、同时通过第二气泵单元接口23b、24b进入第二气泵单元—>第二气容57e—>排气口48d。
以上气路中，如果选用内置氧浓度监测模块，则将外置进气接口41d和外置出气接口42d之间采用软胶管接通，如果选用外置氧浓度监测模块，则将内置进气接口31c和内置出气接口32c之间采用软胶管接通，或者可以采用短接气路零件进行接通。采样气路限流器53e可在气路上产生压差，系统可以测量该压差来计算气体流量。具体的，该限流器53e的两端设置差压传感器51e、52e用于监测气体压差，监测结果将传送至主控模块2，主控模块2通过计算后输出气体流量供工作人员参考。
负压气路中的气体流动顺序为:
负压气路进气口43d—> 负压气路限流器55e—>第一气容54e—>通过第一气泵单元接口21b、22b进入第一气泵单元、同时通过第二气泵单元接口23b、24b进入第二气泵单元—>第二气容57e—>排气口48d。
第一条呼吸力学气路采用以下方式连通：
第二进气口46d（或校零过程中采用较零进气口45d）—三通阀6—通过第一差压采集口62f连通差压传感器。
第二条呼吸力学气路采用以下方式连通：
第二进气口47d（或校零过程中采用较零进气口45d）—三通阀6—通过第二差压采集口63f连通差压传感器—通过表压传感器接口61f连通表压传感器。
以上气体处理装置集成了多种对气体进行处理的气路，简化了气路连接结构，避免了采用软胶管连接气路的环节，因此结构简单、操作方便、且减小了设备体积。气体处理装置还通过主控模块对气体处理过程进行统一控制，并可在主控模块上配置供电电路以及部分传感器，从功能和结构上都提高了系统的集成度，因此显著减小了设备体积，降低了功耗和成本，使用更加方便灵活。
以上气体处理装置可广泛应用与医疗设备或其他气体处理设备中，例如医疗设备为麻醉设备或监护设备，由于气路连接结构简单，且设备集成度高、体积小、更加有利于临床使用。
根据本申请公开的内容，本领域技术人员应当理解，根据设备的需要，在一体化气路板中可以选择性地制作两条、三条或更多条气路，这些气路可以同时使用，也可以选择性的使用，例如使用其中的一部分气路，而关闭或闲置另一部分气路。在另外的实施例中，一体化气路板中的气路还可根据一体化气路板的厚度制作成两层或三层。
以上内容是结合具体的实施例对本发明所作的进一步详细说明，不能认定本发明的具体实施只局限于这些说明。对于本发明所属技术领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本发明的保护范围。
