具体实施方式
下面将结合本申请实施例中的附图，对本申请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申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
请参阅图1，图1是本申请实施例提供的医疗设备100的结构框图。
本申请实施例提供一种医疗设备100，该医疗设备100包括控制器20、呼吸排气系统30和本申请实施例提供的呼吸供气系统10。可以理解的是，医疗设备100的种类可以为多种，包括但不限于呼吸机和麻醉设备，还可以为其他任意满足相应功能要求的设备，在此不对医疗设备100的种类进行具体的限定。
呼吸供气系统10的一端可与外界以及医疗气体制造设备(图未示)连通，相应的，空气由外界进入呼吸供气系统10，医疗气体由医疗气体制造设备进入呼吸供气系统10，空气和医疗气体在呼吸供气系统10中混合形成一定浓度的混合气体；呼吸供气系统10的另一端连接于用户，从而将混合气体输出至用户，以使用户完成相应吸气动作。
需要说明的是，医疗气体的种类有多种，在此不对医疗气体的种类进行具体的限定。示例性的，医疗气体为氧气，相对应的，医疗气体制造设备为制氧机；示例性的，医疗气体还可以为麻醉剂，相对应的，医疗气体制造设备为麻醉剂制造设备。
呼吸排气系统30的一端可连接于用户，另一端可连接于外界或废气收集装置(图未示)，从而用户呼出的废气可通过呼吸排气系统30排出至外界或废气收集装置中，以使用户完成相应呼气动作。
控制器20与呼吸供气系统10连接，以控制调节呼吸供气系统10提供的混合气体的流量以及混合气体中医疗气体的浓度。可以理解的是，控制器20可与呼吸供气系统10内的相应监测部件(如下文中的分支流量监测件1312、总流量监测件141和总浓度监测件142)连接，从而监测得到混合气体的流量以及混合气体中的医疗气体的浓度。并且，控制器20还可与呼吸供气系统10 内的相应调节部件(如下文中的第一调节件1352和第二调节件1311)连接，从而根据监测得到的相应数值，传输相应控制信号至上述调节部件，以调节呼吸供气系统10内空气的流量和医疗气体的流量，从而使得形成的混合气体的流量以及混合气体中医疗气体的浓度满足相应要求。需要说明的是，由于安装了本申请实施例提供的呼吸供气系统10，上述调节过程不会产生较大的热量和噪音。
同样的，控制器20同时还与呼吸排气系统30连接，通过获取呼吸排气系统30的相应参数，以控制呼吸排气系统30排出的废气的流量，在此不进行一一赘述。控制器20分别对呼吸供气系统10和呼吸排气系统30进行控制，使得二者之间协同配合，从而为用户提供机械呼吸的生理需要。
还可以理解的是，在医疗过程中，存在临时阻断吸气过程的需要，如在测量平台压力值时，需阻断用户的吸气过程。在上述情况下，可通过控制器20调节混合气体的流量为零，从而实现吸气阻断功能。需要说明的是，在一些特殊情况下，可能还存在阻断呼气过程的需要，或者存在同时阻断吸气和呼气过程的需要，在上述几种情况下，均可通过控制器20控制呼吸供气系统10以及呼吸排气系统30中的气体流量，以达到相应要求。
本申请实施例提供的医疗设备100，通过安装控制器20、呼吸排气系统30和本申请实施例提供的呼吸供气系统10，从而在实现相应呼吸功能以及阻断功能的同时，有效减小了产生的热量和噪音。
请参阅图2，图2是图1所示医疗设备100中呼吸供气系统10的结构示意图。
本申请实施例提供了一种呼吸供气系统10，该呼吸供气系统10包括第一管路11、第二管路12、第三管路14和本申请实施例提供的气体混合装置13，第一管路11、第二管路12和第三管路14均与气体混合装置13连通，第一管路11用于将空气输入至气体混合装置13；第二管路12用于将医疗气体输入至气体混合装置13；第三管路14用于将气体混合装置13内的混合气体输出。
可以理解的是，第一管路11远离气体混合装置13的一端与外界连通，以使空气可通过第一管路11进入气体混合装置13；第二管路12远离气体混合装置13的一端与医疗气体制造设备连通，以使医疗气体可通过第二管路12 进入气体混合装置13；第三管路14远离气体混合装置13的一端连接于用户，以使混合气体可通过第三管路14输出至用户，从而完成吸气过程。
一种实施例中，第一管路11上设有过滤件112，过滤件112可以对经第一管路11进入气体混合装置13的空气进行过滤，以过滤掉空气中存在的灰尘、杂质、细菌病毒或其他不利于人体健康的物质，进而使输送给用户的气体符合医疗卫生标准。
一种实施例中，第二管路12上设有单向阀122，以保证医疗气体的单向流动，防止气源反向串气。
一种实施例中，第二管路12上还设有第一压力监测件123和压力调节件124，第一压力监测件123用于监测经第二管路12进入气体混合装置13的医疗气体的压力值，压力调节件124用于调节上述医疗气体的压力值，使得经第二管路12进入气体混合装置13的医疗气体的压力不会过大，且具备一定的稳定性。
一种实施例中，第三管路14上还设有总流量监测件141和总浓度监测件142，总流量监测件141用于测量由第三管路14输出的混合气体的流量，总浓度监测件142用于测量由第三管路14输出的混合气体中的医疗气体浓度。可以理解的是，在医疗过程中，用户吸入的混合气体的流量以及混合气体中的医疗气体的浓度，对于医疗效果会产生较大的影响。因此，总流量监测件141和总浓度监测件142的存在，能够有效监测混合气体的流量以及混合气体中的医疗气体浓度。基于此，气体混合装置13能够根据上述监测到的参数，对进入气体混合装置13的空气和医疗气体的流量进行调节，使得二者混合形成的混合气体能够满足相应医疗需求，从而保证较佳的医疗效果。需要说明的是，由于安装了本申请实施例提供的气体混合装置13，上述调节过程不会产生较大的热量和噪音。
本申请实施例提供的呼吸供气系统10，通过安装本申请实施例提供的气体混合装置13，从而在为用户提供满足相应医疗需求的混合气体的同时，有效减小了产生的热量和噪音。
请参阅图3，图3是图2所示呼吸供气系统10中气体混合装置13的结构示意图。
本申请实施例提供一种气体混合装置13，该气体混合装置13包括第一调节组件135、第二调节组件136、混合腔体1341和压缩件1342，混合腔体1341分别与第一调节组件135、第二调节组件136和压缩件1342连通。可以理解的是，本申请实施例中所提到的“连通”通常指的是通过管路连通，也可以通过其他的方式进行气路连通，在此不对连通的方式进行具体的限定。为了便于描述，本申请实施例中提到的“连通”均以管路连通为例进行详细的说明。
第一调节组件135用于调节进入混合腔体1341的空气的流量。空气在由外界进入混合腔体1341的过程中，会经过第一调节组件135，第一调节组件135调节空气的流量，从而使得进入混合腔体1341的空气的流量满足相应要求。
第二调节组件136用于调节进入混合腔体1341的医疗气体的流量。医疗气体在由相应医疗气体制造设备进入混合腔体1341的过程中，会经过第二调节组件136，第二调节组件136调节医疗气体的流量，从而使得进入混合腔体1341的医疗气体的流量满足相应要求。
混合腔体1341为空腔结构，其分别与第一调节组件135和第二调节组件136相连通，从而经第一调节组件135的空气，以及经第二调节组件136的医疗气体均可进入混合腔体1341，并在混合腔体1341内混合以形成满足相应医疗需求的混合气体。
压缩件1342与混合腔体1341连通，压缩件1342用于调节混合腔体1341的内部气压，使得混合腔体1341内部呈负压状态，从而将空气和医疗气体抽入混合腔体1341内，并且，压缩件1342还能够抽取混合腔体1341内的混合气体，并将混合气体进行压缩以输出至用户，从而为用户提供满足相应医疗需求的混合气体。在一种具体的实施例中，压缩件1342为涡轮风扇。
可以理解的是，通过第一调节组件135和第二调节组件136的控制，可使得进入混合腔体1341的空气和医疗气体的流量得到有效调节，从而无需通过频繁调节压缩件1342的功率的方式来控制流量。基于此，在本实施例中，可在压缩件1342的功率保持恒定的情况下，即产生的热量和噪音较小的情况下，有效调节空气和医疗气体的流量，使得提供给用户的混合气体的流量以及混合气体中的医疗气体的浓度能够满足相应医疗需求。
本申请实施例提供的气体混合装置13，通过设置第一调节组件135和第二调节组件136，从而无需频繁调节压缩件1342的功率，即可有效调节空气和医疗气体的流量，在形成满足相应医疗需求的混合气体的同时，减小了产生的热量和噪音。
请参阅图4，图4是图3所示气体混合装置13中第一调节组件135的结构示意图。
一种实施例中，第一调节组件135包括导通件1351和第一调节件1352，导通件1351分别与混合腔体1341以及第一调节件1352连通，第一调节件1352与混合腔体1341连通，第一调节件1352调节导通件1351的开启程度，以调节经导通件1351进入混合腔体1341的空气的流量。可以理解的是，通常情况下，进入气体混合装置13的空气的压力较小，因此，空气难以通过常用的调节阀，从而常用的调节阀难以对进入的空气的流量进行调节。在传统的气体混合装置13中，通常使用吸气保持阀来对空气的流量进行调节，然而，吸气保持阀的体积较大，且价格昂贵，难以满足小型化和低成本的要求。在本实施例中，空气不通过第一调节件1352，而是通过导通面积较大的导通件1351进行传输，从而使得低压力的空气能够有效通过；并且，通过第一调节件1352调节导通件1351的开启程度，能够有效控制进入混合腔体1341的空气的流量。如上所述，由第一调节件1352和导通件1351构成的第一调节组件135，能够对进入混合腔体1341的空气的流量进行有效调节，并且，相对于吸气保持阀，第一调节组件135能够满足小型化和低成本的要求。
一种实施例中，导通件1351包括弹性阀体13511和通气阀口13512，通气阀口13512与混合腔体1341连通，弹性阀体13511设于通气阀口13512远离混合腔体1341的一侧，第一调节件1352调节弹性阀体13511的大小，以调节通气阀口13512的开启程度。其中，通气阀口13512的导通面积较大，使得低压力的空气能够有效通过通气阀口13512进入混合腔体1341；弹性阀体13511设于通气阀口13512远离混合腔体1341的一侧，以对通气阀口13512进行遮挡。
可以理解的是，弹性阀体13511为空心结构，且具备一定的弹性，通过调节弹性阀体13511内部的气压，可改变弹性阀体13511的体积。当弹性阀体 13511的体积增大时，弹性阀体13511对通气阀口13512的遮挡面积增大，从而减小了通气阀口13512的开启程度，空气通过通气阀口13512的流量减小；当弹性阀体13511的体积减小时，弹性阀体13511对通气阀口13512的遮挡面积减小，从而增大了通气阀口13512的开启程度，空气通过通气阀口13512的流量增大。在一种具体的实施例中，弹性阀体13511为硅胶膜片。
一种实施例中，第一调节组件135还包括导通腔体13513，导通腔体13513收容弹性阀体13511和通气阀口13512，空气由外界进入导通腔体13513，并通过导通腔体13513内的通气阀口13512进入混合腔体1341。可以理解的是，导通腔体13513的存在，能够有效避免进入第一调节组件135的空气泄漏，并且，导通腔体13513还能够对导通件1351起到一定的保护作用。
一种实施例中，第一进气接口131与第一调节组件135之间的管路上还设有第二压力监测件1321，所述第二压力监测件1321用于监测进入第一调节组件135的空气的压力，以判断第一进气接口131是否堵塞。
一种实施例中，第一调节件1352包括第一接口13521、第二接口13522和第三接口13523，第一接口13521与弹性阀体13511的内部连通，第二接口13522与外界连通，第三接口13523与混合腔体1341连通；调节第一接口13521与第二接口13522连通，以使弹性阀体13511的内部与外界连通，弹性阀体13511的内部气压等于大气压，从而弹性阀体13511的体积增大，弹性阀体13511封闭通气阀口13512，使得空气无法通过通气阀口13512进入混合腔体1341；调节第一接口13521与第三接口13523连通，以使弹性阀体13511的内部与混合腔体1341连通，由于混合腔体1341内处于负压状态，使得弹性阀体13511的内部气压小于大气压，从而弹性阀体13511的体积减小，通气阀口13512开启，使得空气能够通过通气阀口13512进入混合腔体1341。需要说明的是，通过上述调节方式，能够对弹性阀体13511的大小进行有效调节，从而控制通气阀口13512开启或封闭，以实现吸气导通和吸气阻断功能。还需要说明的是，对弹性阀体13511的体积的调节方式包括但不限于以上一种，还可以为任意满足相应调节要求的方式，在此不对弹性阀体13511的体积的调节方式进行具体的限定。
一种实施例中，第二接口13522和第三接口13523的大小可调，通过调节 第二接口13522和第三接口13523的大小，以控制弹性阀体13511的内部气压大小。可以理解的是，通过调节第二接口13522和第三接口13523大小，能够对弹性阀体13511的内部气压进行有效调节，从而改变弹性阀体13511的体积，以控制通气阀口13512的开启程度，进而调节进入混合腔体1341的空气的流量。在一种具体的实施例中，第一调节件1352为两位三通调节阀。
需要说明的是，可通过控制器20对第二接口13522和第三接口13523的开启或关闭进行控制，从而控制“第一接口13521与第二接口13522连通”和“第一接口13521与第三接口13523连通”这两种状态之间的切换，以实现吸气导通和吸气阻断功能。还需要说明的是，控制器20还可控制第二接口13522和第三接口13523的开启大小，以调节进入混合腔体1341的空气的流量。可以理解的是，相对于手动控制，通过控制器20对上述接口进行控制，能够有效提高控制准确性以及控制效率。
请再次参阅图3，一种实施例中，第二调节组件136包括第二调节件1311和分支流量监测件1312，第二调节件1311用于调节经第二进气孔进入混合腔体1341的医疗气体的流量；分支流量监测件1312用于测量经第二进气孔进入混合腔体1341的医疗气体的流量。在一种具体的实施例中，第二调节件1311为两位三通调节阀。
一种实施例中，气体混合装置13还包括盒体137，盒体137用于收容第一调节组件135、第二调节组件136、混合腔体1341和压缩件1342。其中，盒体137包括第一进气接口131、第二进气接口132和出气接口133。第一进气接口131的一端与第一管路11连通，另一端与第一调节组件135连通，空气自第一管路11经第一进气接口131进入第一调节组件135；第二进气接口132的一端与第二管路12连通，另一端与第二调节组件136连通，医疗气体自第二管路12经第二进气接口132进入第二调节组件136；出气接口133的一端与混合腔体1341连通，另一端与第三管路14连通，混合腔体1341内的混合气体依次经过出气接口133和第三管路14排出。
可以理解的是，盒体137的形状可以为多种，只要能够满足相应收容功能即可，在此不对盒体137的形状进行具体的限定。示例性的，盒体137可以呈空心的正方体状或空心的球体状。还可以理解的是，盒体137还应具备一定的 结构强度，以对收容于其内部的各部件起到一定的保护作用。
需要说明的是，一种实施例中，第二调节组件136还可设于盒体137的外部，第二调节组件136可固定于盒体137的外表面上。在此结构下，第一调节组件135、第二调节组件136、混合腔体1341和压缩件1342同样是共同集成于盒体137，可达到相同的集成效果。
在本实施例中，通过盒体137将第一调节组件135、第二调节组件136、混合腔体1341和压缩件1342等部件集成在一起，使其形成一个整体，从而有效提高了气体混合装置13的集成度，简化了气体混合装置13的安装工艺，提高了工艺效率。
以上所揭露的仅为本申请一种较佳实施例而已，当然不能以此来限定本申请之权利范围，本领域普通技术人员可以理解实现上述实施例的全部或部分流程，并依本申请权利要求所作的等同变化，仍属于申请所涵盖的范围。
