由于医用呼吸机使用的安全性和可靠性直接关系到患者的生命健康，医疗机构必须对呼吸机使用过程中的性能进行周期性的检测和计量校准。按照WS/T 655-2019《呼吸机安全管理》标准的要求，临床在用的呼吸机应每年按照JJF1234《呼吸机校准规范》的要求进行定期计量校准，每次计量校准都涉及多个校准项目。
已有的呼吸机校准装置可通过压力传感器、流量传感器等获取呼吸机患者气体管理中的参数，未连接呼吸机的通讯口，无法读取更无法设置呼吸机的通气模式和运行参数。根据JJF1234《呼吸机校准规范》的要求，每个校准项目均需设置呼吸机的通气模式和运行参数，并通过人工判读的方式从呼吸机的显示屏幕中读取此时“呼吸机监测值”，并与校准装置测得的“测试仪测量值”进行比对，最后人工判定该校准项目的测量误差是否合格，“呼吸机设定值”、“呼吸机监测值”、“测试仪测量值”等校准数据也都需要通过人工方法进行记录。
由于在校准过程中需要对被测呼吸机进行多个通气模式和工作参数的设定，部分校准项目还需要设置模拟肺的顺应性和气道阻力等参数，校准过程需要大量的人工操作，无法实现校准过程的自动化和数字化，无法直接与LIMS等信息化***连接，无法自动出具校准证书，存在校准效率低的技术问题。以及人工操作被测呼吸机、人工读取被测呼吸机的数据以及校准数据的人工记录和计算，这些人为因素也会导致校准结果出现一定的错误率。
因此，现有技术有待于改善。

具体实施方式
应当理解，此处所描述的具体实施例仅仅用以解释本发明，并不用于限定本发明。
需要注意的是，相关术语如“第一”、“第二”等可以用于描述各种组件，但是这些术语并不限制该组件。这些术语仅用于区分一个组件和另一组件。例如，不脱离本发明的范围，第一组件可以被称为第二组件，并且第二组件类似地也可以被称为第一组件。术语“和/或”是指相关项和描述项的任 何一个或多个的组合。
如在背景技术中所述，大多数呼吸机校准装置在校准过程中，未连接呼吸机的通讯口，无法读取更无法设置呼吸机的通气模式和运行参数。因此，现有校准装置在校准过程中需要按照校准步骤的要求频繁操作被测呼吸机，无法实现校准过程的自动化，存在校准效率低的技术问题。
为了至少解决背景技术中所提及校准效率低的技术问题，请参见图4-图7所示的校准装置1，本发明提供的校准装置1内部设有第一通讯接口，该第一通讯接口可分别与模拟呼吸装置3的第三通讯接口、呼吸机2上的第二通讯接口连接。该第一通讯接口以RS232串行通讯接口为主，但也支持多种通讯方式，包括WIFI、NFC接口、蓝牙等无线接口，RS485串行通讯口、RJ45以太网接口、USB接口等，这些接口之间的连接所达到的作用是实现呼吸机2、模拟呼吸装置3与校准装置1之间的双向数据通讯，从而获取校准装置1发送的指令和数据，并将被测的呼吸机数据发送至校准装置1。其中，模拟呼吸装置可以是模拟肺，是一种人工制造的模拟肺部呼吸的结构。
如图1所示，本发明的第一实施例提供了呼吸机自动计量校准方法，包括以下步骤：
步骤S10，发送校准许可请求至呼吸机2；
在本实施例中，检测是否接收到建立连接信号，若接收到所述建立连接信号才执行步骤S10的发送校准许可请求至呼吸机。其中，建立连接信号由模拟呼吸装置3与校准装置1建立有线连接后所传输的信号，即当校准装置1的第一通讯接口与模拟呼吸装置3的第三通讯接口连接后，该模拟呼吸装置3会产生建立连接信号，该建立连接信号经第三通讯接口、第一通讯接口传输至校准装置1，则校准装置1基于接收到建立连接信号能够自动识别出需要对呼吸机2进行校准操作，校准装置1发送校准许可请求至呼吸机2，以进行校准请求。
步骤S20，接收呼吸机2根据校准许可请求所反馈的校准指示指令，根据校准指示指令确定工作状态；
在本实施例中，当校准许可请求由校准装置1传输至呼吸机2时，呼吸机2根据校准指示指令反馈校准指示指令，该校准指示指令经呼吸机2的第二通讯接口、第一通讯接口传输至校准装置1，校准指示指令包括授权许可指 令或者不授权许可指令，呼吸机会根据不同的许可指令确定不同的工作状态。例如，可以根据授权许可指令确定全自动工作状态，当校准装置1确定为全自动工作状态时则自动执行校准程序。
步骤S30，在工作状态下根据校准策略分别对呼吸机2的第一工作参数、通气模式以及模拟呼吸装置3的第二工作参数进行设定；所述模拟呼吸装置3与呼吸机2连接；
在本实施例中，校准策略为预存于校准装置1内的校准过程中所需要利用到的校准信息。校准信息可以参考JJF1234《呼吸机校准规范》中的相关规定来制定，该校准信息包括多个校准项目以及与每个校准项目所对应的相关设定信息。其中，第一工作参数包括潮气量VT、呼吸机比I:E、吸气氧浓度FiO2、吸气压力水平IPL、呼气末正压PEEP和呼吸频率f，上述各参数是呼吸机2在进行工作时的运行参数。通气模式包括PCV模式和VCV模式，PCV模式和VCV模式是呼吸机2在进行工作时的两个不同通气模式。第二工作参数包括气道阻力和顺应性，气道阻力和顺应性是模拟呼吸装置3工作时的两个参数。具体的，除了进行设定之外，校准装置1在全自动工作状态下根据校准策略会对被测的呼吸机2的第一工作参数和通气模式进行自动切换。
其中，所述模拟呼吸装置3与呼吸机2连接表示模拟呼吸装置3与呼吸机2之间形成有通气管道。
步骤S40，获取第一测量参数和第二测量参数，第一测量参数为校准装置1测量得出的参数，第二测量参数为呼吸机2内部监测的参数；
在本实施例中，第二测量参数是呼吸机2内部的第一传感器所读取到的参数，即该第二测量参数是呼吸机2本身对于通气管道进行监控所得到的气体流量参数。第一测量参数为校准装置1上的第二传感器测量得出的气体流量参数，该第二传感器置于气体管道内，该气体管道为呼吸机2与模拟呼吸装置3之间气体流通的管道。
步骤S50，根据通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数输出校准结果。
在本实施中，校准装置1依次对各校准项目测试过程中获取的通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数进行记录和存储，并自动按照JJF1234《呼吸机校准规范》的要求，自动计算各校准项目的 测量误差并做出符合性判定。在自动计量校准过程中，校准装置1屏幕依次显示各校准项目的校准结果，该校准结果包括单项数据报告和总报告，单项数据报告为每个校准项目对应的报告，总报告为所有校准项目对应的报告，每个报告会至少含有通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数。在校准装置1输出校准结果后，可将校准结果同步至LIMS信息***。
在上述实施例中，本发明针对医用呼吸机计量校准的特殊应用场景，结合JJF1234《呼吸机校准规范》的具体要求，利用计算机自动控制与测量技术，利用呼吸机2自身的第二通讯接口，控制呼吸机2配合校准过程的要求自动设置通气模式和运行参数，并同步读取第一测量参数和第二测量参数，实现了呼吸机2校准的自动化和智能化，大幅提升了呼吸机2计量校准的工作效率，并降低了手动校准过程中由于人为操作失误而导致的结果错误率。通过该自动计量校准方法和装置，可以方便地自动出具数字校准证书并与LIMS等信息***连接，实现医用呼吸机计量校准的数字化和信息化。
图2示出本发明的第二实施例所提供的呼吸机自动计量校准方法。第二实施例是第一实施例中的细化实施例，第二实施例所提供的呼吸机自动计量校准方法包括：
步骤S100，发送校准许可请求至呼吸机2；
步骤S101，接收呼吸机根据校准许可请求所反馈的校准指示指令，根据校准指示指令确定工作状态；
在校准指示指令为授权许可指令时，工作状态为全自动工作状态；即根据授权许可指令确定全自动工作状态；
步骤S102，在全自动工作状态下确定各校准项目以及与各校准项目对应的相关设定信息；
步骤S103，根据所述相关设定信息对呼吸机的第一工作参数、通气模式以及模拟呼吸装置的第二工作参数进行设定；
步骤S104，获取第一测量参数和第二测量参数；
步骤S105，根据通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数输出校准结果。
在本实施例中，当校准指示指令为授权许可指令，则校准装置1所确定 的工作状态为全自动工作状态。校准装置1在全自动工作状态下根据校准策略确定一个校准项目以及与一个校准项目对应的相关设定信息，根据所述相关设定信息对呼吸机的第一工作参数、通气模式以及模拟呼吸装置的第二工作参数进行自动化设定，同时校准装置1在全自动工作状态下根据校准策略会对被测的呼吸机2的第一工作参数和通气模式进行自动切换，从而当得到通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数时自动输出校准结果。即当校准装置1处于全自动工作状态时，用户无需亲自输入参数以对呼吸机2的第一工作参数、通气模式以及模拟呼吸装置的第二工作参数进行设定，主要由校准装置1来进行自动化设定。
在本实施例中，授权许可指令携带有远程控制信息，在工作状态下根据校准策略分别对呼吸机2的第一工作参数、通气模式以及模拟呼吸装置3的第二工作参数进行设定之前，包括：
经第一通讯接口发送远程控制信息至呼吸机2的第二通讯接口，远程控制信息用于促使呼吸机2的工作模式调整为待校准模式；所述第一通讯接口为校准装置1上的接口。
在具体使用场景下，当呼吸机2所反馈的是授权许可指令，表明呼吸机2是可以进行校准的呼吸机2，由于呼吸机2所反馈的授权许可指令会携带有远程控制信息，该远程控制信息可以是校准密码，则校准装置1将校准密码经第一通讯接口发送至第二通讯接口，即能够通过该校准密码将呼吸机2的工作模式调整为待校准模式，以便于实现远程的模式调节操作，即自动化地对于呼吸机2在校准过程中所需要涉及到的第一工作参数、通气模式进行设定。
在本实施例中，根据相关设定信息对呼吸机2的第一工作参数、通气模式以及模拟呼吸装置3的第二工作参数进行设定之前，包括：
经第一通讯接口发送验证请求信息至模拟呼吸装置3的第三通讯接口，验证请求信息为校准装置1的第一通讯接口与模拟呼吸装置3的第三通讯接口建立有线连接后自动产生的信号；
检测是否接收到验证成功信号，验证成功信号为模拟呼吸装置3根据验证请求信息所反馈的信号；
若接收到验证成功信号，则执行根据相关设定信息对呼吸机2的第一工作参数、通气模式以及模拟呼吸装置3的第二工作参数进行设定的步骤。
在具体使用场景下，当校准装置1的第一通讯接口与模拟呼吸装置3的第三通讯接口连接时会自动产生验证请求信息，校准装置1将该验证请求信息经第一通讯接口、第三通讯接口发送至模拟呼吸装置3以进行验证，该验证请求信息的作用是验证模拟呼吸装置3是否为可自动校准的模拟呼吸装置，显然当模拟呼吸装置3根据验证请求信息反馈验证成功信号时，该验证成功信号经第三通讯接口、第一通讯接口传输至校准装置1，也即校准装置1能够检测到该验证成功信号，则校准装置1可以执行自动化校准过程中的自动设定步骤，也即执行根据相关设定信息对呼吸机2的第一工作参数、通气模式以及模拟呼吸装,3的第二工作参数进行设定。
需要说明的是，当所接入的模拟呼吸装置3为可通过第三通讯接口进行控制的模拟肺时，可以根据相关设定信息对模拟呼吸装置的第二工作参数进行自动设定；当所接入的模拟呼吸装置3为不具有第三通讯接口的模拟肺时，需用户在模拟呼吸装置3上的参数设定界面上输入信息以对于第二工作参数进行手动设定。
该第二实施例所提供的呼吸机自动计量校准方法还包括：
在校准指示指令为不授权许可指令时，工作状态为半自动工作状态，即根据不授权许可指令确定半自动工作状态；
步骤S111，在全自动工作状态下确定各校准项目以及与各校准项目对应的相关设定信息；
步骤S112，根据相关设定参数对呼吸机2的第一工作参数、通气模式进行设定；
步骤S113，发送第一控制信息至模拟呼吸装置3，第一控制信息用于触发模拟呼吸装置3输出参数设定界面，参数设定界面用于接收用户所输入的信息以对模拟呼吸装置3的第二工作参数进行设定；
步骤S114，获取第一测量参数和第二测量参数；
步骤S115，根据通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数输出校准结果。
在本实施例中，当校准指示指令为不授权许可指令，则校准装置1所确定的工作状态为半自动工作状态。校准装置1根据相关设定参数对呼吸机2的第一工作参数、通气模式进行自动设定，然后发送第一控制信息至模拟呼 吸装置3，促使该模拟呼吸装置3输出参数设定界面，当用户在模拟呼吸装置3的参数设定界面上输入信息后，则完成对于模拟呼吸装置3的第二工作参数的手动设定。即当呼吸机2所反馈的是不授权许可指令时，表明表明呼吸机2是已输出校准结果的呼吸机，无需再进行自动校准，如果还需要进一步精细校准只能由用户亲自参与，通过手动校准的方式进一步校准。即当校准装置1处于半自动工作状态时，一部分的参数设定需要由校准装置1来自动设定，另一部分参数由用户来手动设定，具体的：用户需要亲自输入参数以对模拟呼吸装置3的第二工作参数进行手动设定，呼吸机2的第一工作参数、通气模式进行自动化设定。
具体的，获取第一测量参数和第二测量参数包括：
发送获取请求至呼吸机2，接收呼吸机2根据获取请求所反馈的第一传感器的第二测量参数；该获取请求用于呼吸机2将第一传感器所读取的第二测量参数发送至校准装置1，该第一传感器设置于所述呼吸机2内部；
获取第二传感器所读取的第一测量值，根据第一测量值计算第一测量参数，第二传感器与校准装置1连接，第二传感器设置于气体管道内。
在本实施例中，第一测量参数是对校准装置1的第二传感器所获得的第一测量值进行计算后所得到的测量参数，第二测量参数是由呼吸机2内部的第一传感器直接读取的参数。
图3示出本发明的第三实施例所提供的呼吸机自动计量校准方法。该第三实施例对于第二实施例中的根据通气模式、第一工作参数、第二工作参数、第一测量参数和第二测量参数输出校准结果步骤进行具体细化，上述步骤包括：
步骤S1051，根据相关设定信息确定与通气模块、第一工作参数、第二工作参数对应的第一标准参数以及第二标准参数；
在本实施例中，获得通气模块、第一工作参数、第二工作参数后，根据校准策略可以确定与通气模块、第一工作参数、第二工作参数对应的第一标准参数以及第二标准参数。由于校准策略中所包含的相关设定信息是可参考JJF1234《呼吸机校准规范》的相关规定来设定，也就是说相关设定信息包含多组通气模块、第一工作参数、第二工作参数、第一标准参数、第二标准参数相匹配的数据，所以可以根据所得到的通气模块、第一工作参数、第二工 作参数筛选出与通气模块、第一工作参数、第二工作参数对应的第一标准参数以及第二标准参数。
步骤S1052，根据第一测量参数与第一标准参数计算第一结果值，根据所述第二测量参数与所述第二标准参数计算第二结果值；其中，第一结果值为第一测量参数减去第一标准参数所得的差值，第二结果值为第二测量参数减去第二标准参数所得的差值。
步骤S1053，若第一结果值和第二结果值均小于预设判定阈值，则生成校准合格标识；
步骤S1054，将通气模块、第一工作参数、第二工作参数、第一测量参数、第二测量参数和校准合格标识作为校准结果输出。
本实施例中，当第一测量参数减去第一标准参数所得的差值、第二测量参数减去第二标准参数所得的差值均小于预设判定阈值，表明经校准装置1所校准的呼吸机2满足JJF1234《呼吸机校准规范》的校准评定规定，则生成校准合格标识，最后将通气模块、第一工作参数、第二工作参数、第一测量参数、第二测量参数和校准合格标识作为校准结果输出，并将通气模块、第一工作参数、第二工作参数、第一测量参数、第二测量参数、校准合格标识以及呼吸机编号同步传输至LIMS信息***连接，实现医用呼吸机计量校准的数字化和信息化。其中，LIMS是英文单词Laboratory Information Management System的缩写，表示实验室信息管理。
如图4-图6，分别为实施例4-实施例6所提供的三种关于呼吸机2、校准装置1和模拟呼吸装置3之间的连接方式。
第一种连接方式如图4所示，校准装置1的第二传感器包括且不限于气体流量传感器、气体压力传感器、温度传感器、氧浓度传感器，上述第二传感器设置于气体管道内，气体管道直接接通于模拟呼吸装置3和呼吸机2之间。
具体的，该校准装置1的第二传感器中的气体流量传感器的数量为两个，分别为采集第一气体流量的第一气体流量传感器以及采集第二气体流量的第二气体流量传感器。该校准装置1还执行以下步骤：分别对第一气体流量、第二气体流量进行转化以得到对应的测量参数，根据多个测量参数按照同一管道进行分组关联，检测各组中的每个测量参数是否存在大于预设标准阈值 的测量参数，在确定存在大于预设标准阈值的测量参数时，将大于预设标准阈值的测量参数从各组中进行过滤，得到多组标准测量参数，将多组标准测量参数进行合成，得到第一测量值。由此通过对于两个气体流量进行分析，最终基于多源监测机制从中选择最精准的数据来达到提高校准装置1对于气体管道内的数据的检测准确度，对于校准装置1的后续校准也有所帮助。
第二种连接方式如图5所示，气体管路分为吸气管路和呼气管路，吸气管路一端和呼气管路一端均连接于呼吸机2上，吸气管路另一端和呼气管路另一端合并成一路形成用于放置第二传感器的放置区域，该放置区域连接于模拟呼吸装置3上。
第三种连接方式如图6所示，气体管路分为吸气管路和呼气管路，吸气管路一端和呼气管路一端均连接于呼吸机2上，吸气管路另一端和呼气管路另一端经分路接口(具有两路的Y型接口)连接于模拟呼吸装置3上。
其中，在上述三种连接方式中，当模拟呼吸装置3上没有第三通讯接口时，在对模拟呼吸装置3进行第二工作参数设定时需要用户进行手动设定。
