Description

一种心肺转流系统 技术领域
本发明涉及用于体外生命支持的医疗器械领域，尤其涉及一种心肺转流系统。
背景技术
心肺转流系统，又称体外膜式氧合(extracorporeal membrane oxygenation,ECMO)，为一种可经皮置入的机械循环辅助技术。心肺转流系统通常由主机、泵头和膜式氧合器三个部分构成。主机对心肺转流系统的运行进行控制和监测，泵头用于使体内外的血液进行循环，膜式氧合器用于提供氧气并交换体内排出的血液内的二氧化碳。心肺转流系统主要引流患者体内的静脉血液至体外，经过膜式氧合器氧合并排除血液中的二氧化碳后的血液回输患者体内。根据血液回输的途径不同，心肺转流系统主要有静脉到静脉(venovenous ECMO,VV-ECMO)和静脉到动脉(venous-arterial ECMO,VA-ECMO)两种形式，前者仅具有呼吸辅助作用，而后者同时具有循环和呼吸辅助作用。
由于心肺转流系统通常用于病人急救及医院间病人转运，但心肺转流系统的主机重量大于10公斤，主机内的电源能不需连接市电使用，但其独立工作时间较短，导致心肺转流系统的携带性不佳。当然也能选择不使用主机，直接通过电池直接供电给泵头，泵头直接驱动膜式氧合器运转，但在此模式下，因没有主机而无法侦测从体内排出的血液的流量及气泡，反而带来安全隐患。
发明内容
本发明实施例提供一种心肺转流系统，以解决心肺转流系统不易携带的问题。
为了解决上述技术问题，本发明是这样实现的：
提供了一种心肺转流系统，其包括监测主机、携带式监测主机、泵及膜式氧合器，该监测主机及该携带式监测主机电性连接该泵，该泵通过管路连接该膜式氧合器，该泵及该膜式氧合器分别通过医用插管与体内血管连接，当该体内血管的血液通过该泵及该膜式氧合器进行循环时，该监测主机及该携带式监测主机监测该血液的状态。
在本发明实施例中，通过设置监测主机及携带式监测主机，双监测主机能分开使用，也能同时使用。监测主机与携带式监测主机同时使用时，由双监测主机分担系统的运作，如此简化携带式监测主机及监测主机的系统复杂度，大幅降低携带式监测主机及监测主机的功耗。

携带式监测主机11的携带式处理器1111传输电机控制信号至电机驱动及控制电路1114，电机驱动及控制电路1114根据电机控制信号启动及控制电机模块114运作，电机模块114驱动泵12运作，泵12引流患者体内的静脉血液往体外流，并流至膜式氧合器13。静脉血液于膜式氧合器13中进行氧合以排除血液中的二氧化碳，经膜式氧合器13处理的血液最后流回患者体内的静脉血管或动脉血管。
同时，监测主机10的传感模块103的多个传感器及携带式监测主机11的携带式传感模块113的传感器对血液状态进行侦测，携带式传感模块113所产生的传感信号传输至携带式处理器1111，携带式处理器1111对传感信号进行处理。监测主机10的传感模块103所产生的多个传感信号通过传感信号转换电路1013进行预处理，经携带式处理器1111及传感信号转换电路1013处理的多个传感信号均传输至第一处理器1011，第一处理器1011根据多个传感信号获得血液的状态数据，血液的状态数据能储存于储存模块106内。第一处理器1011根据多个传感信号产生显示信号，并传输显示信号至显示模块104，显示模块104根据显示信号显示血液的状态数据，血液的状态数据的来源是根据多个传感信号，如此有利于使用者监控患者的血液状态。同时使用者通过输入模块105于第一处理器1011设定血液的状态的监测门槛值，第一处理器1011能根据多个传感信号获得血液的状态数据，并判断血液的状态数据是否超过对应的监测门槛值，若判断血液的状态数据有超过对应的监测门槛值时，第一处理器1011产生警示信号，并传输警示信号至显示模块104，显示模块104根据警示信号产生警示信息，使用者可通过观看显示模块104所显示的警示信息进行其他医疗措施。
请参阅图6及图7，其是本发明第二实施例的心肺转流系统的使用状态图及携带式监测主机的框图；如图所示，上述实施例是说明监测主机与携带式监 测主机能同时使用，本实施例说明携带式监测主机11能单独使用，监测主机11单独使用时，携带式电源模块112所提供的电源可为外部的直流电源或电池1123。本实施例的电源模块112使用外部的直流电源，外部的直流电源与电源模块112中变压电路11122电性连接的第二直流电接口1122b电性连接，直流电源信号通过变压电路11122调整其电压，经调整的直流电源信号传输至携带式监测主机11的携带式处理器1111、携带式传感模块113的流量传感器1131与电机模块114的电机，使携带式监测主机11的各模块能正常运作。
接着携带式处理器1111先产生电机控制信号，并传送电机控制信号至电机驱动及控制电路1114，电机驱动及控制电路1114根据电机控制信号驱动及控制电机模块114，使电机模块114驱动泵12运作。泵12开始运作后，引流体内的静脉血液通过膜式氧合器13氧合，膜式氧合器13输入经氧合的血液至患者体内的静脉血管或动脉血管。于血液循环的过程中，携带式传感模块113的流量传感器1131侦测血液的流量，并产生流量传感信号，且传送流量传感信号至携带式处理器1111，携带式处理器1111处理流量传感信号，以根据流量传感信号得知目前血液流量。使用者能先于携带式处理器1111内先设定血液流量的监测门槛值，携带式处理器1111判断血液流量是否超过监测门槛值，若判断血液流量超过监测门槛值时，携带式处理器1111产生警示信号，所以本实施例的携带式监测主机11还包括警示模块115，警示模块115电性连接携带式控制模块111的携带式处理器1111，携带式处理器1111产生警示信号并传送警示信号至警示模块115，警示模块115根据警示信号产生警示信息，其中警示模块115可为警示灯或蜂鸣器，所以警示信息可为灯光信息或声音信息，使用者能通过警示信息作其他的措施。
单独使用携带式监测主机11是于紧急状态下使用，紧急状态包括急救、医院间转运、监测主机发生故障。携带式监测主机11的重量小于监测主机的重量，能有效提升携带式监测主机11的携带性。另外携带式监测主机11的携带式电源模块112能使用车载的直流电源及内建电池1123的直流电源，所以 携带式监测主机11能在缺乏稳定电源的情况下使用，有效提升携带式监测主机11的携带性。同时携带式监测主机11中有设置携带式传感模块113能监测患者血液的状态，使在紧急状态下也能具有良好的安全性。携带式传感模块113仅设置核心的流量传感器1131，如此降低携带式监测主机11的复杂度及功耗，延长携带式监测主机11的工作时间。
请参阅图8及9，其是本发明第三实施例的心肺转流系统的使用状态图及监测主机的框图；如图所示，第一实施例是说明监测主机与携带式监测主机能同时使用，第二实施例是说明携带式监测主机能单独使用，本实施例说明监测主机10能单独使用，监测主机10单独使用时，传感模块103内的传感器能作调整，可增加主要的传感器(例如:流量传感器)，减少辅助的传感器(例如：温度传感器、压力传感器、血氧饱和度传感器)，本实施例的传感模块103相对于第一实施例的传感模块增加流量传感器1030的设置。
电源模块102所提供的电源可为外部的交流电源、外部的直流电源或电池1023。本实施例的电源模块102使用外部的直流电源，外部的直流电源与电源模块102中与变压电路10122电性连接的直流电接口1022电性连接，直流电源信号通过变压电路10122调整其电压，经调整的直流电源信号传输至监测主机10携带式第一处理器1011、传感模块103的流量传感器1030、温度传感器1031、压力传感器1032、血氧饱和度传感器1033、第二处理器10133与显示模块104，使监测主机10的各模块能正常运作。
监测主机10内未设有电机模块，避免监测主机10的重量增加，所以监测主机10需搭配内建电机模块的泵12进行使用。第一处理器1011先产生电机控制信号，并传送电机控制信号至泵12，泵12根据电机控制信号开始运作。泵12开始运作后，引流体内的静脉血液通过膜式氧合器13氧合，膜式氧合器13输入经氧合的血液至患者体内的静脉血管或动脉血管。于血液循环的过程中，传感模块103的流量传感器1030、温度传感器1031、压力传感器1032、血氧饱和度传感器1033分别侦测血液的流量、温度、压力与血氧饱和度，并 分别产生流量传感信号、温度传感信号、压力传感信号及血氧饱和度传感信号，且传送流量传感信号、温度传感信号、压力传感信号及血氧饱和度传感信号至第二处理器10133，第二处理器10133预处理流量传感信号、温度传感信号、压力传感信号及血氧饱和度传感信号，第二处理器10133传输预处理的流量传感信号、温度传感信号、压力传感信号及血氧饱和度传感信号至第一处理器1011，第一处理器1011根据预处理的流量传感信号、温度传感信号、压力传感信号及血氧饱和度传感信号得知目前血液的流量、温度、压力及血氧饱和度等血液的状态数据。使用者能通过输入模块105先于第一处理器1011内先设定流量、温度、压力及血氧饱和度的监测门槛值，携带式处理器111判断血液流量、温度、压力及血氧饱和度中至少一者是否超过对应的监测门槛值，若判断血液流量、温度、压力及血氧饱和度中至少一者超过监测门槛值时，第一处理器1011产生警示信号，并传送警示信号至显示模块104，显示模块104根据警示信号显示警示信息，使用者能通过警示信息作其他的医疗措施。
本实施例的监测主机10的电源模块102能使用市电的交流电源，也能使用车载的直流电源，还能使用内建电池1023的直流电源，所以监测主机10能于没有稳定电源的状态下使用，于没有稳定电源的状态下交叉使用车载的直流电源及内建电池1023的直流电源，以延长监测主机10于没有稳定电源的状态下的工作时间。
综上所述，本发明提供一种心肺转流系统，通过设置监测主机及携带式监测主机，双监测主机能分开使用，也能同时使用。监测主机与携带式监测主机同时使用时，携带式监测主机内设置核心传感器，监测主机内设置辅助传感器，由双监测主机分担系统的运作，如此简化携带式监测主机及监测主机的系统复杂度，大幅降低携带式监测主机及监测主机的功耗。携带式监测主机的重量小于监测主机的重量，于紧急状态下能仅使用携带式监测主机。
