  • Acute pediatric intussusception is a common surgical acute abdomen in infants and young children. It is mainly concentrated in infants between 2 and 36 months. The incidence of male infants is twice that of female infants, that is, the probability of three to one. It refers to a symptom in which one section of intestine is inserted into another section of intestine, forming a folded shape like a straight telescope when stored. Although intussusception may occur in any part of the intestinal tract, the junction of the ileum and colon is the most common location. In most intussusceptions, the proximal intestine is inserted into the distal intestine.

本发明涉及医疗器械技术领域，具体的，涉及一种肠套叠复位***以及应用于该***的肠套叠复位方法。
【背景技术】
急性小儿肠套叠是一种婴幼儿常见外科急腹症，主要集中于2到36个月的婴儿上，男婴的发生机率较女婴大两倍，即三比一的机率。其是指一段肠道套入另一段肠道的一种症状，形成像直筒式望远镜收纳时一般的折叠状。虽然任何部分的肠道都有可能发生肠套叠，但是其中以回肠与结肠交会处是最常发生肠套叠的位置。绝大部分的肠套叠是近端的肠道套入远端的肠道，这是因为肠道的蠕动会将近端肠道拉往远端肠道，因此近端肠道被远端肠道套叠的情况较为常见，不过相反的远端肠道套叠入近端肠道偶尔也会发生。在我国发病率较高，占婴儿肠梗阻的首位。
小儿肠套叠治疗方法分非手术疗法和手术疗法两种。其中，在非手术疗法中有在X射线透视下的空气灌肠复位肠套叠和B超监视下的液体灌肠复位术，空气灌肠复位已被长期广泛应用，空气灌肠法需要在X射线透视下进行，患儿长时间暴露在X射线下会对健康有不利影响，而且操作时医生距离患者较远，不便观察病情及及时抢救处理；手术治疗即剖腹肠套叠复位术，因其创伤大、并发症多而不作为首选，只作为非手术治疗失败后的二线治疗方法。
而对于非手术治疗的两种方法，空气灌肠复位肠套叠的缺点有X射线辐射对于医患两者的伤害、以及少数气压造成肠破裂后引起的气腹症，因而逐渐在临床实践中被淘汰。B超下水压灌肠复位疗法因其因其超声图像特异性和诊断准确率高、复位成功率高、从而成为临床推荐的常用方法。
上述B超监视下的液体灌肠复位术中，目前常用的灌肠装置均为医生临时拼凑。很多医生发表的论文中提到，其将球囊导尿管的一端***患者***，通过向导尿管球囊注入一定容积的气体或液体使得球囊膨胀，防止导尿管在压力作用下滑出***。导尿管的另一端连接一个三通，三通的另 两端分别连接血压测量用的压力表(汞柱表)和进水管，进水管的另一端***液体容器，从而将具有一定压力的液体灌入患儿肠腔，通过液体压力推挤套叠部肠管及其附属部分例如肠系膜等逐步后退，最终实现肠管的复位。采用这种方法的缺点在于其压力表需要人工观察从而造成判读误差，并且直接受到肠内容物的污染，清洁消毒困难，容易造成交叉感染。而且非规范地拼凑手术装置，很容易陷入医疗卫生法规不合规的境地，且易引起医患纠纷。随着汞柱表受到环境保护法规限制逐步退出市场，血压测量改用电子血压计，该种临时拼凑式灌肠装置也将无以为继。
申请号为CN201020175622.5的中国发明专利申请公开了一种可调压限压式灌肠器，提出了一种一次性灌肠用耗材结构，其整套装置为一次性使用。其采用指针式压力表进行管路内流体的压力测量，同样具有人工判读的误差并且精度一般只能达到量程的±10％左右；其机械式调压限压阀的精度也较低，造成过压保护的可靠性下降；而且压力表和调压限压阀一次性使用后就必须抛弃以避免交叉污染，不符合经济原则，增加了医疗成本。
另外，该专利方法的另一个缺点是：操作医生必须依靠人力挤压单向阀注水球囊，向肠内灌注液体；再依靠球囊的弹力从进水容器吸入液体；如此不断重复操作，造成医生的体力负担过大。
采用超声图像监视下的液体肠套叠复位术，医生应密切注视套叠部横切面同心圆征和纵切面半岛型套筒征的变化，而前述已有技术和方法中，医生不得不耗费体力和注意力于灌注压力监控、灌注液体注入等工作，使医生面临多重体力和精神负荷，降低反应的敏捷性，从而影响复位术的成功率和安全性。如能提供一种自动控制灌注速度、压力，并有超压自动安全泄流降压的***和方法，将对肠套叠复位术带来明显的益处。
【发明内容】
本发明的主要目的是提供一种通过灌注液体速度控制、灌注液体压力控制、主动泄压控制等联动控制，以提高肠套叠复位术中复位压力控制的便利性和实时性，减轻医生负担，提高患者安全的肠套叠复位***。

此外，一次性耗材结构主要包括***部、进液部、废液排出部和压力监测连接部等。其中，***部能够经******患者的肠道内，且前端具有充起球囊，***后，可以通过后端的球囊充起接口，将球囊充起，以避免使用时***部从***脱落；进液部能够同灌注液体相连，将灌注液体通过管路输送到患者肠道内，进行灌肠复位；在完成灌肠复位后，主动泄压装置启动，患者肠道内的液体会经废液排出部排出，并且在灌肠复位中，当设备监测到灌注压力达到或超过预设的最大灌注压力时，主动泄压装置启动，患者肠道内的液体会经废液排出部排出，降低患者肠道内的压力，保证患者安全。

一种肠套叠复位方法实施例：
上述肠套叠复位方法包括：在确定肠套叠复位***处于工作状态时，将一次性耗材结构200与肠套叠复位设备100连接后，将***部10经患者******患者肠道内，并经***部10的球囊充起接口12将充起球囊11充起；由流速调节装置3控制调节自动进液装置1的速率，以预定的速率向一次性耗材结构200的进液部20泵入灌注液体101，其中，当压力控制装置2监测到的实时灌注压力小于设定的最大灌注压力时，由主控***8控制自动进液装置1启动进液，同时控制主动泄压装置4停止工作，进液部20和***部10形成通路，由所述通路控制灌注液体101流向患者体内，即可执行肠套叠复位动作。
进一步的，肠套叠复位设备100还包括液体加热装置5，液体加热装置5用于加热灌注液体101并实时检测灌注液体101温度变化。
进一步的，肠套叠复位设备100还包括废液收集装置6，废液收集装置6用于收集废液排出部排出的废液。
进一步的，当压力控制装置2监测到的实时灌注压力大于等于设定的最大灌注压力时，由主控***8控制自动进液装置1停止进液，同时控制主动泄压装置4工作，以降低一次性耗材结构200管路内的压力。
进一步的，肠套叠复位设备100还包括报警单元，当压力控制装置2 监测到的实时灌注压力大于等于设定的最大灌注压力时，主控***8输出报警信号至报警单元。
具体地，在肠套叠复位***工作之前，将一次性耗材结构200和肠套叠复位设备100连接在一起后，将灌注液体101放入肠套叠复位设备100的液体加热装置5。其中，灌注液体101可以采用生理盐水或医生允许使用的其他液体，可以为密封式的软袋包装或者为开放式的瓶体；液体加热装置5可以设置加热所达到的温度，并能够监测到灌注液体101的温度，且当灌注液体101的温度达到设定值时，能够保持灌注液体101的恒温。当然，本实施例所列举的温度设定值，包含但不限于设定的温度值，灌注液体101的实时温度值，加热时间等，均能够在设备上的信息显示装置7上显示，并能够被用户方便获取。
在本实施例中，压力控制装置2能够设定最大灌注压力值，同时与压力监测连接部40连接后能够实时监测灌注压力，当压力控制装置2监测到的实时灌注压力大于等于设定的最大灌注压力时，会进行报警，同时会经过主控***8控制自动进液装置1停止进液，同时控制主动泄压装置4工作，降低管路内的压力。当然，本实施例所列举的设定的最大灌注压力值，包含但不限于设定的最大灌注压力，灌注液体101的实时压力值，报警信息等，均能够在信息显示装置7上显示，并能够被用户方便获取。其中，主控***8作为整个***中用于做出最终决策和发出控制作用的机构，主控***8一般是根据子控制***的反馈作用发出控制指令，如PC端。
特别地，为了保证用户能够及时的注意到报警信息，可以采用声音，灯光，或者两者组合的方式进行报警。
在本实施例中，将一次性耗材结构200的进液部20和自动进液装置1、灌注液体101相连。进液部20可以为单一的管路，在管路的末端可以具有穿刺结构，能够方便接入灌注液体101。自动进液装置1的主要组成可以为一个或者多个可控制的蠕动泵，将进液部20放置入蠕动泵，并通过蠕动泵将灌注液体101泵入管路。流速调节装置3可以调节蠕动泵的速率，通过蠕动泵的不同速率，可以以不同的速率泵入灌注液体，慢的速率泵入液 体的流速慢，快的速率泵入液体的流速快。其中，采用蠕动泵还可以避免灌注液体与自动进液装置1直接接触，避免对灌注液体101造成污染。当然，本实施例所列举的流速，包含但不限于灌注液体101的流速，以及通过流速计算出的灌注液体101的流量，均能够在信息显示装置7上显示，并能够被用户方便获取。
在本实施例中，将一次性耗材结构200的废液排出部30同废液收集装置6、主动泄压装置4相连。其中，废液排出部30可以为单一的管路，管路的末端直接置入废液收集装置6，废液收集装置6可以为开放或者密封的容器；主动泄压装置4的主要组成可以是可控制的压断阀，将废液排出部30置入压断阀中，在正常情况下，压断阀压断管路，20进液部和***部10形成通路。灌注液体101会经此通路进入患者体内。当复位完成时，蠕动泵停止工作，且压断阀释放管路，此时废液排出部30及***部10形成通路，灌注液体101会经此通路由患者体内因压差作用流入废液收集装置6。当灌注时，监测到的管路内灌注液体101的压力大于或等于设定的最大灌注压力值时，蠕动泵也会停止工作，且压断阀释放管路，此时废液排出部30和***部10形成通路，灌注液体101会经此通路由患者体内因压差作用流入废液收集装置6，降低患者体内的压力值，以保证患者安全。
在具体应用中，首先启动肠套叠复位设备100，并将灌注液体101放置入液体加热装置5，并连接好一次性耗材结构200和肠套叠复位设备100，设定好灌注液体101加热温度，并启动加热，等待灌注液体101达到所需温度。
然后，将***部10经患者******患者肠道内，并经***部10的球囊充起接口12将充起球囊11充起。
接着，设定最大灌注压力值，并启动自动灌注。期间通过流速调节装置可以调节灌注流速。其中，最大压力值可以由低到高逐步设置，当一个低的最大灌注压力值不能成功复位时，可以适当调高最大灌注压力值，进行复位操作，直至成功进行复位。
在本实施例中，主控***8可以控制压力控制装置2实时或者按照特 定的时间间隔采集、处理并传送管路压力数据，并且根据监测所得的灌注压力与预先设定的最大灌注压力值进行比较，以控制自动进液装置1及主动泄压装置4等动作。
在正常状态下，管路内的压力小于设定的最大灌注压力值时，自动进液装置1启动，主动泄压装置4停止，进液部20和***部10形成通路，灌注液体101会经此通路进入患者体内。
在非正常状态下，管路内的压力大于或等于设定的最大灌注压力值时，自动进液装置1停止，主动泄压装置4启动，废液排出部30和***部10形成通路，灌注液体101会经此通路由患者体内因压差作用流入废液收集装置6。
在本实施例中，连接有电源***9，用于网电源和内部电池供电的自动切换、电源分配管理、内部电池充放电管理等。
其中，液体加热装置5为非必须项，即可以采用室温的灌注液体进行复位灌注，且已被证明切实可行。
其中，废液收集装置6为非必须项，用户可以选择其他容器进行废液收集，如医院现有的废液收集容器(废液桶)等进行废液的收集。
由此可见，本发明的肠套叠复位方法通过自动进液装置1能够泵入灌注液体，减少操作医生的工作量；压力控制装置2可以设置肠套叠复位时灌注液体101的最大灌注压力，并能够实时监测灌注液体101的压力；流速调节装置3能够按照要求调节灌注流速；主动泄压装置4在监测到在灌注液体101的压力达到或超过预设的最大灌注压力时，能够主动泄压，降低灌注液体101的压力；液体加热装置5可以将灌注液体101加热，并能够实时监测温度的变化，并控制灌注液体101随时处于一个合适的温度，以使患者肠道具有更好的耐受度；废液收集装置6可以收集灌肠复位后的液体，以避免交叉感染。
此外，***部10能够经******患者的肠道内，且前端具有充起球囊11，***后，可以通过后端的球囊充起接口12，将球囊充起，以避免使用时***部10从***脱落；进液部20能够同灌注液体101相连，将灌注液 体101通过管路输送到患者肠道内，进行灌肠复位；在完成灌肠复位后，主动泄压装置4启动，患者肠道内的液体会经废液排出部30排出，并且在灌肠复位中，当设备监测到灌注压力达到或超过预设的最大灌注压力时，主动泄压装置4启动，患者肠道内的液体会经废液排出部30排出，降低患者肠道内的压力，保证患者安全。
所以，该方法通过灌注液体速度控制、灌注液体压力控制、主动泄压控制等***联动控制，可以提高肠套叠复位术中复位压力控制的便利性和实时性，减轻医生负担，提高患者安全。
需要说明的是，以上仅为本发明的优选实施例，但发明的设计构思并不局限于此，凡利用此构思对本发明做出的非实质性修改，也均落入本发明的保护范围之内。
