Description

一种恒压变流式气腹机
本申请要求于2020年06月15日提交中国专利局、申请号为202010540723.6、发明名称为“一种恒压变流式气腹机”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
技术领域
本发明涉及气腹机设备技术领域，特别是涉及一种恒压变流式气腹机。
背景技术
气腹机作为腹腔镜手术的标准配置，在诸如肝胆外科、胃肠外科等都起到了向腹腔内充气，以便获得良好手术操作空间的作用。气腹机是腔镜手术的重要设备，它使手术的部位或腔体充气隆起，便于医生观察诊断。由于该设备属于微压微流精密控制设备(工作压力一般在0-30mmHg，最大输气量一般小于40LPM)，因此存在设备制备难，设备使用分险大等问题，因为气压失控必将给手术带来严重影响，还可能危及病人的生命安全。
现有的腹机采用的是供气与测压分时进行的周期性控制技术，压力调节区间误差范围大，供气流量变化非线性，在开关阀的作用下，会产生压力脉冲。该压力脉冲峰值常常超出压力设定值，而在泄气量变化较大的动态情况下，气腹机的输出气压最高甚至可以达到40mmHg，远远超出了临床安全临界值，同时，脉冲状的供气容易导致患者腹腔收到压力冲击，且由于手术时间的不确定性也导致了设备调控周期不稳定，控压精度差等，因此需要研制一款更加简单的实现恒压变流过程的气腹机。

为使本发明的上述目的、特征和优点能够更加明显易懂，下面结合附图和具体实施方式对本发明作进一步详细的说明。
参见图1，一种恒压变流式气腹机，包括壳体1，所述壳体1的外侧分别设有气腹机进气口11、气腹机出气口12、除烟进气口13以及除烟出气口14；所述气腹机进气口11通过减压阀A101与外接气源102连接，所述的外接气源优选为二氧化碳，所述的气腹机出气口12通过过滤器A103与患者腹腔连接，所述的除烟进气口13通过过滤器B104与患者腹腔连接，所述的除烟出气口14与负压吸引器105连通，优选的，所述的气腹机进气口11与除烟出气口14位于壳体的同一侧，所述的气腹机出气口12与除烟进气口13位于壳体的同一侧，这样有利于保证气腹机整体运行的连贯性；所述壳体1内设有控制模块2、气动模块3、温度检测模块4、安全模块5、温控模块6以及除烟模块7；所述的控制模块2分别与气动模块3、温度检测模块4、安全模块5、温控模块6和除烟模块7信号连接，用于系统驱动以及对采集的数据进行数字信号处理；所述的气动模块3用于控制外接气源输送的气体压力、温度和流量；所述的温度检测模块4用于检测外接气源输送的气体温度；所述的安全模块5用于检测控制模块和气动模块的温度；所述的温控模块6用于对机箱内降温的同时降低噪声；所述的除烟模块7用于将患者腹腔产生的烟气排出。
参见图2，本实施例中，所述的气动模块3包括过滤器C31、压力传感器A32、加热减压阀33、安全阀34、压力传感器B35、比例阀模块36、流量传感器37和开关阀模块38；所述过滤器C31的一端通过管道与气腹机进气口11连接，另一端通过管道与加热减压阀33的一端连接；所述加 热减压阀33的另一端通过管道与安全阀34的一端连接；所述安全阀34的另一端通过管道与比例阀模块36连接；所述比例阀模块36的一端通过管道与流量传感器37的一端连接；所述流量传感器37的另一端通过管道与开关阀模块38的一端连接，所述开关阀模块38的另一端与气腹机出气口12连接，所述的流量传感器37与控制模块2信号连接；所述过滤器C31与加热减压阀33之间的管道上设有压力传感器A32，所述压力传感器A32与控制模块2信号连接；所述安全阀34与比例阀模块36之间的管道上设有压力传感器B35，所述压力传感器B35与控制模块2信号连接。其中，加热减压阀33用于对气体的加热以及初次减压，安全阀可以用于保证气体在初次减压时处于安全的状态，比例阀模块36可以自动调整输出气体量，并根据内置算法，实现气体的稳定输出，流量传感器37用于在保证恒压的状态下控制输出至患者腹腔的气体流量。
参见图3，本实施例中，所述的比例阀模块36包括并联连接的第一气路和第二气路，所述的第一气路和第二气路不同时打开；其中，所述的第一气路由减压阀C361、压力传感器C362和比例阀C363组成，所述的第二气路由减压阀D364、压力传感器D365和比例阀D366组成；所述的减压阀C361的一端通过管道与压力传感器B35连接，减压阀C361的另一端通过管道与比例阀C363连接，比例阀C363的另一端通过管道与流量传感器37连接，减压阀C361与比例阀C363之间的管道上设有压力传感器C362，所述压力传感器C362与控制模块2信号连接；所述的减压阀D364的一端通过管道与压力传感器B35连接，减压阀D364的另一端通过管道与比例阀D366连接，比例阀D366的另一端通过管道与流量传感器37连接，减压阀D364与比例阀D366之间的管道上设有压力传感器D365，所述压力传感器D365与控制模块2信号连接。在实际操作过程中，由于对进入患者腹腔的气体压力是有要求的，一般为10～15mmHg，因此所述比例阀模块中任意的气路中都需要设置一个的压力传感器，例如当开启第一气路时，减压阀C361对气体进行二次减压，通过压力传感器C362对其进行检测，当压力传感器C362检测的测量值与预设的时候进入患者腹腔的压力值吻合时，气体则通过后置的比例阀C363直接输出，当检测的测量值过高或过低时，气体则通过比例阀C363进行调节，实现其稳定 输出；本实施例中，第一气路可以得到相对精确的高流量输出，第二气路可以得到精确的低流量输出，两个气路可以对应不同的控制范围，彼此之间可以自动切换，以满足各种实际应用中的要求。
参见图4，本实施例中，所述的开关阀模块381包括开关阀A381、开关阀B382、压力传感器E383和压力传感器F384，所述的开关阀A381和开关阀B382之间不同时开启或关闭；所述开关阀A381的一端与流量传感器37连接，所述开关阀A381的另一端与气腹机出气口12连接，开关阀A381与气腹机出气口12之间的管道上设有压力传感器E383和压力传感器F384，所述的压力传感器E383和压力传感器F384之间串联连接；所述压力传感器E384的一端通过管道与开关阀B382连接。当执行送气过程时，开关阀A381打开，开关阀B382关闭，气体通过开关阀A381，最终进入患者腹腔；当执行排气过程时，开关阀B382打开，而开关阀A381关闭，气体通过开关阀B382排入大气，其中压力传感器C383和压力传感器D384保证了同一通路气压的二次测量，如果偏差大于设定，则系统会自动报警，如偏差在范围内，则使用平均值带入算法运算，保证了系统的安全性。
本实施例中，所述的温度检测模块4包括温度传感器A41和温度传感器B42，所述的温度传感器A41设于过滤器C31与压力传感器A32之间的管道上，温度传感器A41与控制模块2信号连接；所述的温度传感器B42设于压力传感器F384与气腹机出气口12之间的管道上，温度传感器B42与控制模块2信号连接。温度传感器A41可以检测刚进入气动模块的气体的温度，这样可以避免气体运输过程中对后续气动模块中的各类阀门造成损伤；温度传感器B42可以检测进入患者腹腔前的气体的温度，避免由于气体温度过高而对患者身体造成的损伤。
本实施例中，所述的安全模块5包括温度传感器C51和温度传感器D52，所述的温度传感器C51设置在加热减压阀33外侧，温度传感器C51与控制模块2信号连接，用于检测加热减压阀33的温度，由于热减压阀33是气动模块的核心部件，其是否能稳定的运作将直接影响整体的通气效果，因此本发明可以直接对加热减压阀33运作时的温度进行监测；所述的温度传感器D52安装在控制模块2上，直接与控制模块2信号连接 信号，用于检测控制模块2的温度，这样可以直接检测主控模块运行时的实时温度。
本实施例中，所述的温控模块6包括风扇61和温度传感器E62，所述的风扇61安装在控制模块2的底部，控制模块2与风扇61之间通过电路连接；所述温度传感器E62安装在壳体1内，与控制模块2信号连接信号，用于检测环境温度；所述控制模块2接收温度传感器E62输入的温度，并控制风扇61开启对壳体1内部进行降温。一般的气腹机中均存在风扇用于对其进行物理降温，但气腹机在运行过程中会受到外界环境因素的影响，而传统气腹机的风扇是一直旋转的，因此会带来较高的噪音。本发明通过温度传感器E62可以对外接环境的温度进行监测，当外接环境温度较低时(低于20℃)，控制模块可以接收到当下的温度并控制风扇不工作，这就为室内的手术创造了安静的环境，当外界温度过高时，控制模块则会根据温度控制风扇转动对气腹机进行降温。此外，温度传感器E62和温度传感器D52之间还可以通过数据的比较来判断控制模块是否运行正常，这也为气腹机的正常运作提供双重的保障。
本实施例中，所述的除烟模块7包括开关阀C71、过滤器D72、颗粒探测器A73、颗粒探测器B74和调速气泵75；所述开关阀C71的一端通过管道与除烟进气口13连接，开关阀C71的另一端与过滤器D72连接，过滤器D72的另一端通过管道与调速气泵75的一端连接，过滤器D72与调速气泵75之间的管道上依次连接有颗粒探测器A73和颗粒探测器B74，所述的颗粒探测器A73和颗粒探测器B74均与控制模块2信号连接；所述的开关阀C71与控制模块信号2连接；所述调速气泵75的另一端通过管道与除烟出气口14连接。作为更优选的方案，所述的颗粒探测器A73为PM10探测器；所述的颗粒探测器B74为PM2.5探测器。当腹腔镜手术开始，电刀开始工作，腹腔内烟雾开始产生。先是控制模块2控制开关阀C71开启，然后调速气泵75开启，除烟模块中开始有气流通过，气体先通过过滤器A103将其中的油污、水汽和PM10以上的大颗粒过滤，然后气体通过过滤器D72，这是防止由于过滤器A103损坏而进行的双重过滤，处理后气体先经过颗粒探测器A73即PM10探测器，PM10探测器将检测到的数值传递给控制模块，当该数值大于阙值，则表示前端 过滤器失效，系统继续运行则可能损坏探测器，系统报警并进入待机状态，如果没有报警，表示系统状态正常；随后，气体进入颗粒探测器B74即PM2.5探测器，颗粒探测器B74将检测的数值传递给控制模块，由于电切的材料都属于人体组织，成分相对稳定，可以认为腹腔内的原始气体成分中PM2.5和PM10的相对比例固定，故在此可以推算出腹腔内原始气体成分，根据PM2.5探测器的探测值，控制调速气泵75的调速过程，探测值和转速对比表作为预设存入控制模块，根据预设表确定气泵的转速，重复执行以上步骤，即可实现自动控制，如有特殊情况需要停止自动只要触摸按键关闭即可。
本实施例中，所述的壳体1内还设有触摸屏8，所述的触摸屏8与控制模块2信号连接，用于对气腹机内各模块输出的数据进行显示。
本实施例中，所采用的控制模块可以是常规的单片机或其他控制系统，各类过滤器，各类压力传感器、各类温度传感器、各类开关阀、流量传感器，安全阀、各类减压阀等部件均为通用标准件或本领域技术人员知晓的部件，其结构和原理均可通过技术手册得知或常规试验方法获知。
本发明的使用过程：
当气腹机开启时，气动模块开始运作，外接的气源在过滤器C31的作用下进行除杂处理，处理后气源直接通过加热减压阀33，安全阀34，比例阀模块36，流量传感器37，开关阀模块38，气腹机出气口12，过滤器103进入患者腹腔；当需要进行除烟功时，部分气体可以通过过滤器104，从患者腹腔进入气腹机除烟口13，并通过开关阀71，过滤器72，颗粒探测器73，颗粒探测器74，调速气泵75，除烟出气口14，最终进入负压吸引器。由于本设备自动化程度高，对于普通医护人员使用者，在连接气路后，只要在触摸屏界面调节预设压力和预设流量，按送气键即可使用，如需要对气体加热/关闭加热，只需在触摸界面单击加热键，如需排除腹腔内烟雾/关闭排烟，只需要在触摸界面单击除烟键。
本说明书中各个实施例采用递进的方式描述，每个实施例重点说明的都是与其他实施例的不同之处，各个实施例之间相同相似部分互相参见即可。对于实施例公开的系统而言，由于其与实施例公开的方法相对应，所以描述的比较简单，相关之处参见方法部分说明即可。
本文中应用了具体个例对本发明的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本发明的方法及其核心思想；同时，对于本领域的一般技术人员，依据本发明的思想，在具体实施方式及应用范围上均会有改变之处。综上所述，本说明书内容不应理解为对本发明的限制。
