本发明涉及麻醉机领域，尤其涉及一种电动麻醉呼吸装置。
背景技术
麻醉机是主要用于在病人手术期间给其提供氧气、麻醉及呼吸支持的设备。麻醉机在机械通气领域存在电动和气动两种结构，并有相应的呼吸***与它们配合使用，例如：循环再呼吸***。在循环再呼吸***中，病人呼出的部分气体将作为吸入气体被重复吸入，这样有利于保持病人吸入气体的温度和湿度；同时，麻药作为一种比较昂贵的气体成分被保留下来，对于减少环境污染和节约成本起到非常重要的作用。应该注意的是，在多数的麻醉呼吸设备中，都提供手动和自动通气两种方式，医疗专业人员针对麻醉治疗的不同阶段和临床需要可以通过手动和自动选择开关，选择手动的通气方式。
麻醉呼吸装置的电动通气控制方式相较于气动方式在节省气体跟使用方便性上具有明显的优势。现有电动麻醉呼吸装置的电动通气控制主要采用活塞、涡轮等结构，其主要存在如下问题：由于活塞、涡轮置于麻醉呼吸***当中，涡轮的叶轮、转轴和叶轮壳体都与麻醉气体和病人呼出气体直接接触，消毒和维护作业繁琐。此外，由于涡轮属于精密器件，杂质的存在和腐蚀会直接影响到涡轮的工作性能和机器的控制精度。现有的一种方式是在呼吸端口和吸收罐之后增加过滤器，以减轻涡轮部件被污染的程度，但长时间使用和实际使用的差异导致清洁和维护的问题无法完全避免，维护成本较高，且会影响客户的满意度。
发明内容

其中，增压泵为涡轮。
其中，放射装置为容量反射器。
其中，容量反射器包括细小管路，用以对由增压泵推进至容量反射器中的驱动气体和麻醉呼吸***中的气体进行隔离。
其中，所述电动麻醉呼吸装置还包括接入在所述第二气体通道中的用以测定呼出气体peep值的呼气阀。
为解决上述技术问题，本发明还提供的一种技术方案：一种电动麻醉呼吸装置，包括：麻醉呼吸***，电动麻醉呼吸装置还包括：用以向麻醉呼吸***提供驱动动力的电动增压装置；连接在电动增压装置上用以向麻醉呼吸***传递和施加驱动动力的反射装置，反射装置包括驱动气体入口和驱动气体出口，电动增压装置连接在驱动气体入口上，驱动气体出口连接在麻醉呼吸***上，其中：电动增压装置包括：连接在驱动气体入口上的增压泵。

附图说明
为了更清楚地说明本发明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单地介绍，显而易见地，下面描述中的附图仅仅是本发明的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1是本发明实施例电动麻醉呼吸装置的结构框图。
具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本发明保护的范围。
参见图1，为本发明电动麻醉呼吸装置的实施例一。
本实施例中的电动麻醉呼吸装置，包括：麻醉呼吸***、容量反射器2以及电动增压装置3，其中：容量反射器2包括驱动气体入口21和驱动气体出口22，电动增压装置3连接在驱动气体入口21的一端，驱动气体出口22的一端接入连接在麻醉呼吸***中。电动增压装置3通过容量反射器2连接麻醉呼吸***，并向麻醉呼吸***提供驱动动力。
本实施例中的麻醉呼吸***包括：用以输入氧气和麻醉剂的气体输入口 11、用以供病人进行呼气和吸气的呼吸端口12；分别连接在气体输入口11和呼吸端口12之间的第一气体通道13，第一气体通道13中接入吸气单向阀14；
分别连接在气体输入口11和呼吸端口12之间的第二气体通道15，第二气体通道15中接入呼气单向阀16，气体输入口11和呼气单向阀16之间接入用以吸收二氧化碳的吸收装置17。
其中：分别设置第一气体通道13和第二气体通道15，且在第一气体通道13中设置吸气单向阀14，在第二气体通道15中设置呼气单向阀16，是为了建立病人通过呼吸端口12进行吸气或呼气时相互独立的气体通道，一方面可对病人呼出的气体进行收集，将其作为病人吸气时吸气气体的一部分被重复吸入，另一方面有利于保持病人吸入气体的温度和湿度，也可以将较为昂贵的麻药成分保留下来，其可以对减小环境污染和节约成本起到重要的作用。
进一步的，输入氧气和麻醉剂由气体输入口11输入，气体输入口11分别连接第一气体通道13和第二气体通道15。其中，在第一气体通道13中接入吸气单向阀14后连至呼吸端口12；在第二气体通道15中依次接入用以吸收二氧化碳的吸收装置、驱动气体出口22、用以测定呼出气体peep值的呼气阀4以及呼气单向阀16后连至呼吸端口12。具体实施时，吸收装置可以使用二氧化碳吸收罐17或其它具有吸附某单一气体或多种气体能力的装置。吸收罐17可以对通过其气体中的二氧化碳进行吸收，包括如图所示气体由上至下通过该装置或由下至上通过该装置双向进行吸收的情况。当然，也可以不设置呼气阀4，或将其设置在电动麻醉呼吸装置的其它位置对呼出气体的peep值进行测定，例如呼气阀4可以设置在驱动气体入口21的位置，并不影响实施。
容量反射器2在本实施例中主要是由细小管路组成的设备，其包括驱动气体入口21和驱动气体出口22，驱动气体入口21连接电动增压装置3，驱动气体出口22连接在麻醉呼吸***的上述吸收装置17和呼气单向阀16之间。
将容量反射器2设置为细小管路的作用是：其可以对由电动增压装置3 推进至容量反射器2中的驱动气体和麻醉呼吸***中的气体进行隔离，防止麻药的损失。同时，容量反射器2也可以给病人提供持续的气流，避免通气中断。
可以理解的是：容量反射器2的容积需要大于病人所需的潮气量，也就是能够满足病人的吸入气量，其也能够最大程度的节省麻药的使用量。同时，容量反射器2也可以被其它反射装置进行替代，例如折叠囊或隔膜反射装置等，其能够在病人吸气和呼气转换时，将一定量含有麻药成分的气体进行储存。
电动增压装置3用以向麻醉呼吸***提供驱动动力，其在本实施例中包括分别连接在驱动气体入口21上的增压泵31和排气阀32。具体地，增压泵31可以设置为涡轮等能够从外界吸入气体并对其进行增压的设备。增压泵31连接驱动气体入口21，在当增压泵31从外界空气中吸入气体后能够进行增压，并通过容量反射器2将容量反射器2中含有麻药成分的气体连同由气体输入口11输入的呼吸气体推动至呼吸端口12供病人吸气使用。排气阀32连接在驱动气体入口21上，其作用是当病人呼出气体通过容量反射器2中时，容量反射器2中的多余气体将通过排气阀32排出。需要说明的是：当上述容量反射器2由折叠囊进行替换时，排气阀32也相应的设为***阀，当有多余气体使折叠囊达到顶端时，麻醉呼吸***中的气体会通过***阀排出。同时，使用容量反射器2相对于使用折叠囊的技术方案，容量反射器2的接口更简单，在更换和维护上更显简便。
本发明的电动麻醉呼吸装置在具体实施时，病人通过呼吸端口12吸气，增压泵31从外界空气吸入气体并增压，增压气体由驱动气体入口21进入容量反射器2并对其中的气体进行推动，由于容量反射器2由细小管路组成，其可以提供持续的气流，能够避免通气中断，还可有效隔离驱动气体和麻醉呼吸***中的气体。由于驱动气体出口22接入在吸收装置17和呼气单向阀16之间，呼气单向阀16能够阻止气体由该侧进入呼吸端口12。由驱动气体出口22排出的气体经吸收装置17的吸收后，去除其中的二氧化碳与由气体输入口11输入的含有氧气和麻醉剂等的新鲜气体汇合，通过吸气单向阀14后达到呼吸端口12处。当病人呼气时，吸气单向阀14阻止呼出气体进入第 一气体通道13，呼出气体通过呼气单向阀16以及呼气阀4后进入容量反射器2。在此过程中，由气体输入口11输入的含有氧气和麻醉剂等的新鲜气体也可经吸收装置17进入容量反射器2，容量反射器2中的多余气体将通过排气阀32排出。呼气阀4可以测定病人呼出气体的peep值。
实施本发明的电动麻醉呼吸装置的其它实施方式中，呼气阀4还可以设置在驱动气体入口21，此时，可以不设置排气阀32。同时，也可以使用除涡轮外的其它气体增压设备，并不影响实施。
实施本发明的电动麻醉呼吸装置，具有如下有益效果：
将为麻醉呼吸***提供驱动动力的电动增压装置放置在麻醉呼吸***的外部，相对于传统以气动方式向麻醉呼吸机提供驱动气体的方式更加节省气体、使用也更为方便；同时，也可以免于对涡轮等增压泵进行清洁维护，可以降低装置的维护成本。
进一步地，电动增压装置通过容量反射器向麻醉呼吸***提供连续的气流，可以保证通气的连续性，能够避免通气中断。
