Description

麻醉呼吸系统及其消毒控制方法
【技术领域】
本发明涉及一种医疗器械，特别涉及麻醉呼吸系统及其消毒控制方法。
【背景技术】
麻醉呼吸机是一种带有循环回路的设备，其中循环回路是细菌与病毒存留的重要部位。在反复使用中，麻醉呼吸机内部回路管道中存留的致病菌极易造成医源性感染，诸如引发VAP（机械通气相关性肺炎）、热源反应、HBV（乙型肝炎病毒）、HCV（丙型肝炎病毒抗体）等死亡率很高的并发症。尤其是SARS（严重急性呼吸综合征）、禽流感、艾滋病等极易传播的传染病被列为当前重点预防传播的病种，使得麻醉呼吸机等医疗设备的消毒灭菌工作显得尤为重要。如果病菌存留在这些医疗设备内部，那么由此引发的医源性感染将带来无法估量的危害和损失。
为了实现麻醉呼吸机循环回路的消毒灭菌，目前通常采用的方式是，麻醉呼吸机使用一段时间后，将机器的呼吸回路部分拆下，进行高温高压灭菌或进行戊二醛、环氧乙烷等消毒。此方式需要反复拆装，操作麻烦，甚至因操作不当造成机器的损伤。而且使一般是用一段时间后消毒一次，并且很多情况下一台麻醉机一天会安排多例手术，很难做到每病例逐一消毒，使长期处于无菌状态。
目前国际上对此感染途径的控制也有专门的研究，主要为呼吸过滤器的研制和推广使用。在过滤器中使用了某种复合的滤膜，可以过滤细菌和病毒。但从本质上讲，它是一种被动的隔离措施，各种细菌和病毒都还存活，附着于滤膜和仪器上，还存在交叉感染的危险。另外目前市面上还有针对麻醉呼吸机内部管道的回路消毒机，但其需要从外部接入消毒机，操作上不太方便；并且只能在麻醉机的手动控制状态下使用，不能够对机控状态下的风箱支路进行消毒，消毒不彻底。
【发明内容】
基于此，有必要提供无需拆装便可实现消毒灭菌作用的麻醉呼吸系统。
还有必要提供一种该麻醉呼吸系统的消毒控制方法。

为了便于理解本发明，下面将参照相关附图对本发明进行更全面的描述。附图中给出了本发明的较佳实施例。但是，本发明可以以许多不同的形式来实现，并不限于本文所描述的实施例。相反地，提供这些实施例的目的是使对本发明的公开内容的理解更加透彻全面。
需要说明的是，当元件被称为“固定于”另一个元件，它可以直接在另一个元件上或者也可以存在居中的元件。当一个元件被认为是“连接”另一个元件，它可以是直接连接到另一个元件或者可能同时存在居中元件。
除非另有定义，本文所使用的所有的技术和科学术语与属于本发明的技术领域的技术人员通常理解的含义相同。本文中在本发明的说明书中所使用的术语只是为了描述具体的实施例的目的，不是旨在于限制本发明。本文所使用的术语“及／或”包括一个或多个相关的所列项目的任意的和所有的组合。
请参看图1，本发明第一实施例中麻醉呼吸系统100包括麻醉呼吸机10及集成于麻醉呼吸机10回路内对麻醉呼吸机10回路进行消毒的消毒控制装置30。
麻醉呼吸机10包括通过管道20与病人连通进行通气的呼吸装置11、用于驱动呼吸装置11的驱动装置13以及设置于呼吸装置11与驱动装置13之间的切换阀15。
呼吸装置11包括与管道20连接的呼气管路110与吸气管路112、与呼气管路110连接的呼气单向阀114、与吸气管路112连接的吸气单向阀116、新鲜气体支路118以及吸收罐120。新鲜气体支路118连接于吸气单向阀116与吸收罐120之间，用于向麻醉呼吸机10回路内通入新鲜气体。吸收罐120设置于驱动装置13与吸气单向阀116之间，用于滤除病人呼出气体中的二氧化碳。在本实施例中，吸收罐120内填充有钠石灰。可以理解地，在其它一些实施例中，吸收罐120内可填充其它用于过滤二氧化碳的过滤材料，在此不做限制。另外，新鲜气体支路118亦可设置多个，例如，分别设置于吸气单向阀116进出口的两端。
驱动装置13通过切换阀15与呼气单向阀114及吸气单向阀116连通，以分别与呼气管路110形成供病人呼气的呼气通道及与吸气管路112形成供病人吸气的吸气通道。驱动装置13可在切换阀15的作用下根据用户操作于机控驱动与手控驱动两种模式之间切换。驱动装置13包括机控驱动装置130与手控驱动装置140。在一些实施例中，驱动装置13可以单独采用机控驱动装置130或手控驱动装置140，此时可省略切换阀15。
机控驱动装置130包括与切换阀15连接的风箱装置131、均与风箱装置131连接的吸气阀132与安全阀133以及与安全阀133连接的呼气阀134。风箱装置131内设置有折叠囊135。吸气阀132用于产生驱动气体以压缩折叠囊135，驱使折叠囊135内的呼出气体流向吸收罐120。安全阀133用于排出风箱装置131内过量气体以限制风箱装置131内气体压力。呼气阀134用于排放麻醉呼吸机10回路内的尾气。
手控驱动装置140包括手动皮囊142。手动皮囊142通过手动支臂141外接于切换阀15外。可以理解地，在其它一些实施例中，手动皮囊142也可以直接与切换阀15连接。另外，手动皮囊142可替换为折叠气囊或活塞等方式。
请一参看图2，在本发明第二实施例中，麻醉呼吸系统100中亦可采用曲折气道137代替风箱装置131，以半驱动气体和病人呼出气体进行隔离。
请结合参看图3，消毒控制装置30包括输入单元31、控制单元32、检漏单元33、报警单元34、冲洗单元35、消毒单元36以及监测单元37。
输入单元31用于向控制单元32输入控制指令。其中，输入单元31可为按键或触摸屏等输入设备。控制指令可以是启动冲洗程序的启动信号或是消毒定时设定、消毒起止时间设定、消毒因子浓度设定、消毒持续时间设定或冲洗持续时间设定等中的一项或多项。在其它一些实施例中，控制指令亦可做为默认配置，控制单元31直接提取即可，此时消毒控制装置30中便可省略输入单元31。
控制单元32 用于响应控制指令进行对应的操作。具体地，控制单元32用于响应控制指令控制麻醉呼吸机10切换至消毒模式并控制所述消毒单元36产生消毒因子以对所述麻醉呼吸机10的回路进行消毒灭菌。具体地，控制单元32用于控制切换阀15切换至机控驱动模式，以将呼吸装置11与机控驱动装置13连接，使呼气通道与吸气通道连通并形成供消毒因子流通的回路。
控制单元32还用于响应控制指令控制检漏单元33对麻醉呼吸机10的回路进行泄露测试。其中，检漏单元33可包括设置于麻醉呼吸机10回路上的通气管以及传感器。在进行检漏时，通气管向封闭的麻醉呼吸机10内通入检漏气体，传感器用于对麻醉呼吸机10回路内检漏气体的参数值进行侦测。其中，所述参数值包括检漏气体的气压值和/或浓度值等。
控制单元32还包括检测模块321。检测模块321用于检测麻醉呼吸机10的气体泄漏量是否大于预设的报警阈值。具体地，在消毒操作之前，当检测模块321检测到麻醉呼吸机10的气体泄漏量大于预设的报警阈值时，则产生报警信号；若否，则产生启动信号。在消毒操作时，当检测模块321检测到麻醉呼吸机10的气体泄漏量大于预设的报警阈值时，则产生中断信号。
报警单元34用于响应报警信号发出报警信息。其中，报警信息可为用户预先录制的语音信息和/或蜂鸣等警示音，也可以是发光提示等，在此不作限定。
冲洗单元35用于响应启动信号对麻醉呼吸机10回路进行消毒之前的冲洗。具体地，冲洗单元35用于响应启动信号向麻醉呼吸机10回路内通入大量新鲜气体，对麻醉呼吸机10回路进行消毒操作之前的冲洗。如此，将手术过程中残余的笑气、麻醉气体等冲洗干净，以达到更好的消毒效果。在本实施例中，冲洗单元35可为设置于麻醉呼吸机10回路的新鲜气体支路118(请参看图1)亦可为独立于新鲜气体支路118外用于通入新鲜气体的通道。可以理解地，在其它一些实施例中，冲洗单元35可为采用其它的冲洗方式对麻醉呼吸机10进行冲洗，在此不作限定。
控制单元32还包括定时模块323。定时模块323用于设定冲洗单元35的冲洗持续时间。具体地，冲洗单元35的冲洗持续时间可由用户预先设定并存储于定时模块323内，亦可由用户现场即时设定。
控制单元32用于当冲洗单元35在预设时间内冲洗完成后控制消毒单元36产生消毒因子以对麻醉呼吸机10回路进行消毒灭菌。具体地，控制单元32用于当冲洗单元35冲洗完成后控制消毒单元36产生消毒因子并驱动机控驱动装置13驱动麻醉呼吸机10运行机控通气模式。
在消毒操作时，控制单元32还用于当检测模块321检测到麻醉呼吸机10的气体泄漏量大于预设的报警阈值时，则产生中断信号。消毒单元36用于响应中断信号停止产生消毒因子。
消毒单元36设置于呼气通道和/或吸气通道中，并产生于呼气通道和/或吸气通道中流动的消毒因子。在本实施例中，消毒单元36为设置于麻醉呼吸机10回路中的臭氧发生器。同时，为了使排放入空气中的臭氧残余浓度满足安全要求，可在呼气阀134的尾气排放口安装臭氧消除器136（请参看图1）。同时，为了达到更好的消毒效果，臭氧发生器亦可采用臭氧水蒸汽或臭氧加过氧化氢蒸汽。
其中，消毒单元36设置的位置以及数量均可根据需要而定。
如图1所示，消毒单元36集成于消毒控制装置30内并设置于新鲜气体支路118上，由新鲜气体支路118通入的新鲜气体作为载气携带消毒因子注入麻醉呼吸机10回路中。其中，消毒单元36亦可以自带气泵，从而不需要采用新鲜气体作为载气。
如图4所示，为了达到更好的消毒效果，消毒单元36亦可包括分散设置于吸气单向阀116进出口的两端以及手动支臂141与管道20连接处的消毒单元36a、36b以及36c，以从麻醉呼吸机10回路的多个位置注入消毒因子。
请再次参看图3，定时模块323还用于设定消毒单元36的消毒持续时间。具体地，消毒单元36的消毒持续时间可由用户预先设定并存储于定时模块323内，亦可由用户现场即时设定。控制单元32还用于当消毒单元36在预定时间内消毒完成后控制冲洗单元35对消毒之后的麻醉呼吸机10回路进行冲洗。具体地，控制单元32用于控制冲洗单元35再次通入大量新鲜气体对麻醉呼吸机10回路再次进行冲洗，将回路中残余的臭氧快速冲洗干净，以防回路中残余有臭氧在手术时对人体造成伤害。
控制单元32还用于在消毒单元36对麻醉呼吸机10回路消毒过程中控制监测单元37对消毒单元36产生的消毒因子的参数进行监测。控制单元32还包括用于存储上述消毒因子的参数的存储器325。具体地，监测单元37用于在消毒过程中对消毒单元36产生的臭氧的浓度、温湿度、压力以及流量等参数进行监测，使麻醉呼吸机10回路中的臭氧能够很好地保持在消毒所需的浓度或安全值下，从而更好地保证消毒效果。
请参看图5与图6，下面以第一实施例中详细说明麻醉呼吸系统100的消毒过程：
当需要进行消毒时，将管道20连接至手动支臂141处，从而使呼气管路110以及吸气管路112通过管道20与手动皮囊142连通；控制单元32根据用户的输入操作控制切换阀15将呼吸装置11与机控驱动装置13连接并控制检漏单元33对麻醉呼吸机10回路进行检漏；当麻醉呼吸机10回路未出现漏气现象时，控制单元32控制冲洗单元35在预定时间内向麻醉呼吸机10回路通入大量新鲜气体，以进行消毒操作之前的冲洗；当冲洗操作完成后，控制单元32控制消毒单元36产生消毒因子并驱动机控驱动装置13；在吸气阶段，如图5箭头所示，折叠囊135将回路中的循环气体和随新鲜气体注入的臭氧一起依次沿切换阀15、吸收罐120、吸气单向阀116以及管道20压入手动皮囊142；在呼气阶段，如图6箭头所示，手动皮囊142内混合有臭氧的循环气体依次经管道20、呼气单向阀114以及切换阀15被压入折叠囊135内，多余的气体会从安全阀133和呼气阀134排出，由此完成一次呼吸循环。由于臭氧一直随新鲜气体注入到回路当中，经过若干次呼吸循环以及长时间的保持，回路中的循环气体即可达到消毒和灭菌要求的臭氧浓度并实现有效的消毒灭菌。完成消毒之后，控制单元32控制冲洗单元35再次对麻醉呼吸机10回路再次进行冲洗，将回路中残余的臭氧快速冲洗干净，以防回路中残余的臭氧在手术时对人体造成伤害。
请参看图7，在本发明第三实施例中，麻醉呼吸机10还可在呼气管路110与管道20之间以及吸气管路112与管道20之间分别设置一个切换件16。在本实施例中，切换件16为三通换向阀。两个三通换向阀16用于根据用户的操作控制麻醉呼吸机10于消毒模式与呼吸模式之间来回切换。当两个三通换向阀16分别连接于呼气管路110与手动支臂141以及吸气管路112与手动支臂141之间时，麻醉呼吸机10处于消毒模式；当两个三通换向阀16分别连接于呼气管路110与管道20以及吸气管路112与管道20之间时，麻醉呼吸机10处于呼吸模式。
请再次参看图3，在本实施例中，输入单元31用于向所述控制单元32输入控制指令。其中，输入单元31可为按键或触摸屏等输入设备。本实施例中，控制指令包括第一输入信号与第二输入信号。
控制单元32 用于响应第一输入信号控制麻醉呼吸机10切换至消毒模式，且还用于响应第二输入信号控制麻醉呼吸机10切换至呼吸模式。具体地，控制单元32用于根据第一输入信号控制切换阀15将呼吸装置11与机控驱动装置13连接并控制两个三通换向阀16分别连接于呼气管路110与手动支臂141以及吸气管路112与手动支臂141之间；控制单元32还用于根据第二输入信号控制两个三通换向阀16分别连接于呼气管路110与管道20以及吸气管路112与管道20之间。采用这种方式，在消毒时无需将管道20手动连接至手动支臂141处，便可以利用麻醉呼吸机10自身的呼吸动作将臭氧均匀地分布到回路中各个部位。
请参看图8，本发明还涉及一种麻醉呼吸系统消毒控制方法，其包括以下步骤：
切换至消毒模式；
对麻醉呼吸机10的回路进行泄露测试以检查是否漏气；具体地，若是，则产生报警信号并发出报警信息；若否，则向麻醉呼吸机10的回路中通入大量新鲜气体以对麻醉呼吸机10的回路进行消毒操作之前的冲洗；
产生消毒因子并驱动麻醉呼吸机10进入机控通气模式以对麻醉呼吸机回路进行消毒灭菌；具体地，在进行消毒操作时，对产生的消毒因子的参数进行监测与控制并将获得的数据存储于存储器325内。其中，消毒因子的参数包括浓度、温湿度、压力以及流量等。
向消毒后的麻醉呼吸机10回路中通入大量新鲜气体以对麻醉呼吸机10的回路进行消毒操作之后的冲洗。
请参看图9，在本发明中，消毒控制装置30亦可省略冲洗单元35。其中，消毒单元36用于响应启动信号产生消毒因子以对麻醉呼吸机10回路进行消毒灭菌。该麻醉呼吸系统消毒控制方法包括以下步骤：
切换至消毒模式；
对麻醉呼吸机回路进行泄露测试以检查是否漏气；具体地，若是，则产生报警信号并发出报警信息；若否，则产生消毒因子并驱动麻醉呼吸机10进行机控通气模式以对麻醉呼吸机回路进行消毒灭菌；具体地，在进行消毒操作时，对产生的消毒因子的参数进行监测与控制并将获得的数据存储于存储器325内。其中，消毒因子的参数包括浓度、温湿度、压力以及流量等。
本发明中麻醉呼吸系统100内集成有消毒控制装置30，可通过麻醉呼吸机10自身的气体循环往回路中注入臭氧，实现不拆卸回路自消毒；同时，麻醉呼吸系统100中消毒控制装置30内设置有冲洗单元35以及监测单元37，使消毒前后麻醉呼吸机10有冲洗的流程，消毒过程中麻醉呼吸机10可通过监测单元37对臭氧浓度、温湿度、压力和流量等系统参数的监测和控制，更好地保证消毒效果和冲洗效果。
以上所述实施例仅表达了本发明的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本发明专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本发明构思的前提下，还可以做出若干变形和改进，这些都属于本发明的保护范围。因此，本发明专利的保护范围应以所附权利要求为准。
