Description

一种可同时测量心电与有创血压的采集器及方法 技术领域
本发明涉及心电图及有创血压测量方法领域，特别是一种可同时测量心电与有创血压的采集器及方法。
背景技术
心电图是临床最常用的检查之一，用于对各种心律失常、心室心房肥大、心肌梗死、心肌缺血等病症检查。有创动脉压监测适应于重症疾病、手术过程中，用于精确检测患者动脉压力，可以实时取值可根据动脉波形变化。
心电图是利用心电图机从体表记录心脏每一心动周期所产生的电活动变化图形的技术。在人体不同部位放置电极，以记录和反应心脏的电活动。在行常规心电图检查时，通常只安放4个肢体导联电极和V1～V66个胸前导联电极，记录常规12导联心电图。
而有创压力测量需要动脉导管、压力连接管、压力换能器、连续冲洗系统、压力检测仪。经皮桡动脉穿刺置管法常用于桡动脉、股动脉。动脉导管从穿刺处进入，置于需要测压部位的血管内，将体外导管接口管连接测压装置。
例如中国发明专利《一种有创血压监测装置》，申请号为201720965824.1，其公开了包括包括电源导线、压力传感器连接头、连接管、接口连接块、控制阀、固定杆、装置固定块、压力传感器、调节旋钮、连接端口。其可以通过固定方式将检测装置固定在患者身上，避免移动的困扰。但是该结构也仅仅只能进行有创血压监测，其不具备同步的心电监测能力。因此，患者还需要另外进行心电监测过程，并没有提供便利的效果。
发明内容
本发明目的是：提供一种可同时测量心电与有创血压的采集器及方法，解决了有创血压检测结构上同步实现心电监测的问题。
本发明的技术方案是：一种可同时测量心电与有创血压的采集器，包括：导管、压力管、压力传感器、液体管路、冲洗管路。管路连接方式为：导管连接压力管，压力管通过三通阀连接液体管路，液体管路的两端设置有鲁尔接头，液体管路再连接至冲洗管路。
导管通过穿刺处介入在被检测的血管中，冲洗管路通过液体管路压力管、导管进行排 空和输液。当输液稳定后对液体管路中的液体进行压力及心电监测即可实现同时测量心电与有创血压。
具体的，在液体管路上设置一个管腔，管腔为液体管路的一层外圈，管腔与液体管路隔离。压力传感器的感测头与导电电极均设置于管腔内，在管腔与液体管路之间的管壁上开设通孔，在确保通孔密封性能的前提下，感测头与导电电极从通孔处接触液体管路中的液体。外部，压力传感器及导电电极则通过数据线路连接至压力和心电监测设备。通过液体管路内的混合液(血液和生理盐水)，压力传感器可以获得当前血管内的压力；同时由于混合液具有导电性，因此通过导电电极可以获得此时的心电数据。
一种上述的采集器同时测量心电与有创血压的方法，步骤包括：
第一、通过穿刺部位，将导管介入主动脉的冠脉开口处，压力管连接液体管路及冲洗管路；第二、在冲洗管路上接入生理盐水，通过冲洗排出管路中的空气；通过调整冲洗管路上的冲洗阀来把整个管路中的空气排空并且充满生理盐水。
第三、校准压力传感器，通过调节校零开关使压力传感器读数归零；
第四、将液体管路与导管连接，再将采集器与心脏保持相同的水平高度，完成有创压力和心电的同时检测。
本发明的优点是：该结构简单可靠，既可以测量心电又可以测量有创血压，简化手术操作流程及手术耗材使用，方便快捷为临床提供检测数据。本方法不仅能准确测量有创压力还可以测量心电信号，不必额外增加心电贴片电极及导联线。
附图说明
下面结合附图及实施例对本发明作进一步描述：
图1为采集器的结构图；
图2为同时测量心电与有创血压的临床使用示意图；
其中：1、采集器；2、压力管；3、液体管路；4、冲洗管路；5、压力传感器；6、导电电极；7、数据线路。
具体实施方式
本发明的较佳实施例：
一种可同时测量心电与有创血压的采集器，包括：导管、压力管2、压力传感器5、液体管路3、冲洗管路4。管路连接方式为：导管连接压力管2，压力管通过三通阀连接液体管路3， 液体管路3的两端设置有鲁尔接头，液体管路3再连接至冲洗管路4。
导管通过穿刺处介入在被检测的血管中，冲洗管路4通过液体管路3压力管、导管进行排空和输液。当输液稳定后对液体管路中的液体进行压力及心电监测即可实现同时测量心电与有创血压。
具体的，在液体管路3上设置一个管腔8，管腔8为液体管路的一层外圈，管腔8与液体管路3隔离。压力传感器5的感测头与导电电极6均设置于管腔内，在管腔8与液体管路3之间的管壁上开设通孔，采用胶水将压力传感器5和导电电极6固定在液体管路3管壁的开孔处，使压力感受器5与导电电极6均可与管腔8内的液体接触同时保证管路不会从器件连接处漏液。外部，压力传感器5及导电电极6则通过数据线路7连接至压力和心电监测设备。
因此，通过液体管路3内的混合液(血液和生理盐水)，压力传感器5可以获得当前血管内的压力；同时由于混合液具有导电性，因此通过导电电极6可以获得此时的心电数据。
基于上述的采集器1，同时提供一种上述的采集器1同时测量心电与有创血压的方法，在做介入手术时，首先将介入的导管通过穿刺处沿血管到达主动脉的冠脉开口处，压力管2连接液体管路3及冲洗管路4。其次，使用生理盐水通过冲洗阀把整个管路里的空气排空并充满生理盐水，由于导管尾端通过三通连接压力管2，这样就形成了一个从主动脉一直到采集器1的密闭管路里面充满血液及生理盐水。
接着，通过校零开关将压力传感器5校零。
最后，采集器1水平高度保持与心脏水平，此时压力传感器5采集压力与冠脉口处压力一致，同时由于管路内的血液和生理盐水都具有良好的导电性，通过与液体接触的导电电极6可以测量体内心电。压力传感器5和导电电极6采集的模拟信号通过数据线路7传输到检测设备，完成有创压力和心电的同时检测。
上述实施例仅例示性说明本发明的原理及其功效，而非用于限制本发明。任何熟悉此技术的人士皆可在不违背本发明的精神及范畴下，对上述实施例进行修饰或改变。因此，举凡所属技术领域中具有通常知识者在未脱离本发明的所揭示的精神与技术思想下所完成的一切等效修饰或改变，仍应由本发明的权利要求所涵盖。
