Description

一种可同时供多个心脏外科停跳手术使用的冷热交换系统 技术领域
本发明属于医疗设备领域，具体来说涉及一种可同时供多个心脏外科停跳手术使用的冷热交换系统。
背景技术
在心脏外科停跳手术中，因为心脏处于停止跳动状态但是身体内的血液循环和氧合作用不能停止，所以必须实行体外血液循环。目前被广泛使用于临床的是人工心肺机系统，它是由血泵一组、冷热交换水箱和监护器等配合一次性用品——氧合器及管路组成，其中，血泵提供动力，使身体内的血液在串联有氧合器的闭环中流动。
由于人工血液循环与人的自然血液循环存在相对差别，如果手术过程较长，这种差别可能使人的器官产生损伤(特别是脑组织，可因为缺氧而产生损伤)。为了减少这样的损伤，必须降低人体的新陈代谢水平，减少人体对氧的需要，这样就相对的保护了人体器官。在心外科停跳手术中，冷热交换水箱向氧合器的闭环回路中提供冷水或热水，冷水或热水在氧合器中与血回路进行冷热交换(氧合器中的水回路和血回路是隔离的，通过隔离界面进行热交换)，在手术开始时，用冷水对血液进行降温；在手术结束时，用热水对血液进行升温。监护器采集被手术者的各项体征及其它体外循环中的重要数据，使循环处于正常运转，这样基本构成了一个体外循环的过程。
但是，瑞士监管部门最先发现(后经欧盟及各国监管部门证实)：目前全世界所使用的热交换水箱存在隐患。因为热交换水箱是在手术室内循环使用，一次手术结束后，热交换水箱内仍存在水，剩余的水会滋生大量致病细菌；除此之外，用于使热交换水箱向外输出水的水泵也会因为接触水而产生细菌。最重要的是，产生的细菌在水循环过程中会通过水泵和压缩机的风扇扩散到了空气中，从而进入被手术者开放状态的胸腔内。
目前，已经有报告印证了上述观点。有报告称(S Haller,et al.CONTAMINATION DURING PRODUCTION OF HEATER-COOLER UNITS BY MYCOBACTERIUM CHIMAERA POTENTIAL CAUSE FOR INVASIVE CARDIOVASCULAR INFECTIONS:RESULTS OF AN OUTBREAK INVESTIGATION IN GERMANY,APRIL 2015TO FEBRUARY 2016，Eurosurveillance,Volume 21,Issue 17,28April 2016)，多个发生感染 的患者在心脏外科停跳手术中均使用了同一个来自德国生产商生产的热交换水箱。还有文章(Public Health England，出版物网关号码为2015394)不但公开报道“体外循环和ECMO(extracorporeal membrane oxygenation)过程中冷热交换水箱会产生带菌的气雾，并对患者造成感染”，而且该文章还暗示感染的细菌为结核杆菌。也有文献报道称(
Figure PCTCN2016095633-appb-000001
T,Klassen S,Jonas D,et al.Heater-cooler units:contamination of crucial devices in cardiothoracic surgery.[J].Journal of Hospital Infection,2016.)，发现了多例分支杆菌嵌合体严重感染的病例，且这些患者的感染发生在接受了开胸手术后的数月或数年。
针对于上述发现，冷热交换水箱生产商提出了各种灭菌的方法。例如：紫外线杀菌、药物杀菌和过滤水等方法，但是，采用紫外线杀菌、药物杀菌和过滤水后，虽然细菌数量能立刻减少，但是经过一定时间，细菌数量就恢复到杀菌前的水平，且此时的细菌具有一定抗体。因此，灭菌的方法并不能彻底解决问题。
除此之外，目前，一个冷热交换水箱只能给一台心脏外科停跳手术提供冷热交换，如果医院中同时进行多台心脏外科停跳手术，则每台心脏外科停跳手术都需要一个冷热交换水箱，冷热交换水箱数量的增加导致操作麻烦和增加成本。且每个冷热交换水箱在使用时至少需要提前半小时对该冷热交换水箱进行制冷，等待时间较长，影响心脏外科停跳手术的进行。
发明内容
针对上述技术缺点，本发明的目的是提供一种可同时供多个心脏外科停跳手术使用的冷热交换系统，该冷热交换系统不但可以解决“被手术者感染冷热交换水箱滋生的细菌”的问题，而且还可同时供多台心脏外科停跳手术进行冷热交换，具有操作简便的优点。

具体实施方式
下面结合附图对本发明的可同时供多个心脏外科停跳手术使用的冷热交换系统进行详细说明。
如图1～2所示，包括：安装有五个压缩机2的冷水箱5、电控系统以及与冷水箱5连接的冷热交换装置1，每个冷热交换装置1用于向一台心脏外科停跳手术提供冷热交换，其数量至少为一个(为了更直观的表示，图1中仅示出一个冷热交换装置1)。冷水箱5内设置有一冷水箱循环管道6，冷水箱循环管道6上安装有冷水箱循环泵4，用于循环冷水箱5内的水，使该冷水箱5内水的温度更均衡。
冷热交换装置1包括：主循环水箱1-15、辅循环水箱1-5、两根回水通道1-2、第一调水管道1-1、第二调水管道1-17、第一回路1-13、第二回路1-9和第三回路1-6，主循环水箱1-15和辅循环水箱1-5内分别安装有一个电加热管1-4，在主循环水箱1-15和辅循环水箱1-5的侧壁上分别形成有一溢流孔(图中未示出)，每一溢流孔分别通过一根回水通道1-2与冷水箱5相连，以使高度超过溢流孔的水通过该回水通道1-2溢流至冷水箱5。第一调水管道1-1上安装有第一调水泵1-3，第二调水管道1-17上安装有第二调水泵1-16，冷水箱5的水分别通过第一调水管道1-1和第二调水管道1-17排入主循环水箱1-15和辅循环水箱1-5。
主循环水箱1-15分别安装在第一回路1-13和第二回路1-9上，即主循环水箱1-15分别与第一回路1-13和第二回路1-9连通，第一回路1-13上安装有一第一回路泵1-12和氧合器1-14，以使第一回路1-13内的水与氧合器1-14内的血液进行冷热交换。第二回路1-9上安装有一第二回路泵1-11和变温毯1-10，以使第二回路1-9内的水与变温毯1-10进行冷热交换。
辅循环水箱1-5安装在第三回路1-6上，即辅循环水箱1-5与第三回路1-6连通，第三回路1-6上安装有一第三回路泵1-8，以使第三回路1-6内的水与心脏停搏液回路内的血液进行冷热交换。
电控系统包括：程序控制器7和人机界面8，主循环水箱1-15、辅循环水箱1-5和冷水箱5内分别安装有一个与程序控制器7电连接的温度传感器3，程序控制器7分别与人机界面8、五个压缩机2和两个电加热管1-4电连接，程序控制器7分别与第一调水泵1-3、第二调水泵1-16、第一回路泵1-12、第二回路泵1-11和第三回路泵1-8电连接。
本发明的冷热交换系统可包括一个或多个冷热交换装置1，电控系统可同时控制多个冷热交换装置1分别向多台心脏外科停跳手术提供冷热交换，其中，电控系统控制每个 冷热交换装置1向心脏外科停跳手术提供冷热交换的工作过程均相同，下面对该工作过程进行详细说明：
1、在程序控制器7中写入冷水箱5内水的温度期望值A，通过冷水箱内安装的温度传感器3采集冷水箱内水的温度，得到温度值B；程序控制器7将温度期望值A与温度值B进行比较，并控制压缩机2使冷水箱内水的温度达到温度期望值A；
2、通过人机界面8向程序控制器7写入主循环水箱1-15的温度期望值C，通过主循环水箱1-15内安装的温度传感器3采集主循环水箱1-15内水的温度，得到温度值D；程序控制器7将温度期望值C与温度值D进行比较，控制主循环水箱1-15内安装的电加热管1-4加热或从冷水箱5向该主循环水箱1-15内调冷水，使主循环水箱1-15内水的温度达到温度期望值C；
3、通过人机界面8向程序控制器7写入辅循环水箱1-5的温度期望值E，通过辅循环水箱1-5内安装的温度传感器3采集辅循环水箱1-5内水的温度，得到温度值F；程序控制器7将温度期望值E与温度值F进行比较，控制辅循环水箱1-5内安装的电加热管1-4加热或从冷水箱5向该辅循环水箱1-5内调冷水，使辅循环水箱1-5内水的温度达到温度期望值E；
4、根据氧合器、变温毯和心脏停搏液回路的冷热交换需要，通过人机界面8驱动/停止第一回路泵1-12、第二回路泵1-11和第三回路泵1-8，以完成对氧合器、变温毯和心脏停搏液回路的冷热交换目的。
本发明的冷热交换系统可以解决“被手术者感染冷热交换水箱滋生的细菌”的问题。如图1所示，A线的右方为心脏外科停跳手术室，A线的左方为心脏外科停跳手术室外，该心脏外科停跳手术室外安装有紫外线消毒装置9。其中，氧合器、变温毯和心脏停搏液回路均置于心脏外科停跳手术室内，冷水箱、主循环水箱、两根回水通道、第一调水管道、第二调水管道、第一调水泵、第二调水泵、第一回路泵、第二回路泵、第三回路泵和辅循环水箱均置于心脏外科停跳手术室外。氧合器1-14通过第一快速接头(图中未示出)安装在第一回路1-13上，变温毯1-10通过第二快速接头(图中未示出)安装在第二回路1-9上，冷热交换器1-7通过第三快速接头(图中未示出)安装在第三回路1-6上，以使第三回路内的水流经冷热交换器并与放置在冷热交换器内的心脏停搏液回路进行冷热交换。第一快速接头、第二快速接头和第三快速接头均位于心脏外科停跳手术室内。不但可以阻止冷水箱、主循环水箱和辅循环水箱内所滋生的细菌扩散至心脏外科停 跳手术室的空气中，而且通过第一～第三快速接头可方便进行安装和拆卸。
以上对本发明做了示例性的描述，应该说明的是，在不脱离本发明的核心的情况下，任何简单的变形、修改或者其他本领域技术人员能够不花费创造性劳动的等同替换均落入本发明的保护范围。
