Description

一种提高双气压呼吸机性能的呼吸阀及其呼吸装置 技术领域
本发明涉及一种提高双气压呼吸机性能的呼吸阀，本发明还涉及一种呼吸装置，属于医疗器械领域。
背景技术
呼吸机在临床上主要是解决通气和吸氧问题。近年来，双气压呼吸机由于结构简单，使用方便，价格便宜，广泛被临床甚至家庭采用。双气压呼吸机使用单管连接呼吸机和鼻罩或面罩，连接方便，但也存在一些问题：
一、呼气通道不明确，面罩的泄漏口、带泄漏口的接头、甚至是鼻罩和面罩的边缘的泄漏都是呼气二氧化碳的排放通道。
二、泄漏量不确定。吸气压力是根据病人的情况来设定的，除了考虑病人肺的顺应性、病人潮气量的需求，还要考虑可能存在的重复吸入。泄漏量又取决于气道压力和泄漏的等效口径。
三、由于上述2个原因，在临床上双气压呼吸机通气时二氧化碳潴留风险比较大，大的泄漏量甚至于不能在气道内建立压力，小的泄漏量二氧化碳排放不畅；需要临床经验和双气压呼吸机使用经验比较丰富的医生多次调整才能达到满意的效果。
四、也是由于泄漏量不确定，管道内加氧成为难点。提高吸入氧浓度是临床治疗缺氧的主要手段直接加在连接管道，大部分氧气随着泄漏排到大气，必须浪费大量的氧气才能提高吸入氧浓度。实际的吸入氧浓 度和泄漏量，病人的分钟通气量相关，不确定的泄漏量也意味着不确定的吸入氧浓度
五、由于存在泄漏，双气压呼吸机的供气流量远大于病人的吸气流量。在这种情况下，气体的加温湿化也成为双气压呼吸机的问题之一。
临床的非双气压类的呼吸机工作在不泄漏或者是泄漏很小的条件下，呼出气有专门的呼出通道，几乎不存在重复吸入，呼吸机的供气流量和病人的吸入流量十分接近，加温湿化比较容易。但存在呼吸机价格昂贵，操作复杂的问题。
发明内容
本发明的目的在于提供一种提高双气压呼吸机性能的呼吸阀及其呼吸装置,以解决上述问题。
本发明采用了如下技术方案：
本发明提供一种提高双气压呼吸机性能的呼吸阀，其特征在于，包括：相互扣合的吸气阀盖和呼气阀盖，膜片，设置在吸气阀盖和呼气阀盖的中间，膜片与吸气阀盖所围成的内部空间称为吸气阀腔，膜片与呼气阀盖所围成的内部空间称为呼气阀腔，吸气单向阀，设置在吸气阀腔中，吸气单向阀座，设置在所述吸气单向阀的后面，呼气单向阀片，设置在呼气接口到呼气阀腔之间，以防止重复吸入，呼气阀口，设置在呼气阀腔中，当呼气阀腔压力低于吸气阀腔时，膜片向呼气阀口方向运动，使得呼气阀口关闭，呼气单向阀座，支撑所述呼气单向阀片。
进一步，本发明提高双气压呼吸机性能的呼吸阀的提高双气压呼吸机性能的呼吸阀，还可以具有这样的特征：其中，吸气单向阀座上还包括：加氧接口。
进一步，本发明提高双气压呼吸机性能的呼吸阀的提高双气压呼吸机性能的呼吸阀，还可以具有这样的特征，还包括：氧气单向阀，与加氧接口相连接。
进一步，本发明提高双气压呼吸机性能的呼吸阀的提高双气压呼吸机性能的呼吸阀，还可以具有这样的特征，还包括：积水排出口，设置在呼气阀盖上。
本发明还提供一种呼吸装置，包括如上的呼吸阀，以及：吸气管路、呼气管路以及Y型接头，其中，吸气管路一端与吸气阀腔相连通，另一端与Y型接头相连通，呼气管路一端与呼气阀腔相连通，另一端与Y型接头相连通。
进一步，本发明的呼吸装置，还可以具有这样的特征，还具有：湿化器，设置在吸气管路上。
进一步，本发明的呼吸装置，还可以具有这样的特征，还具有：积水杯，设置在呼气管路上。
进一步，本发明的呼吸装置，还可以具有这样的特征，还具有：双气压呼吸机，与吸气阀腔相通。
发明的有益效果
本发明的提高双气压呼吸机性能的呼吸阀及其呼吸装置，双气压呼吸机一旦连接本发明的呼吸阀和管道，可以达到大型或者是专业型的呼吸机无创通气的效果。
1.呼气气体有专门的排放通道，二氧化碳不易发生潴留现象。
2.呼气气体专门的排放通道可以收集病人呼出气体，特别是有通过呼吸传染的病人使用呼吸机。
3.吸气通道内有吸气单向阀，病人呼出气不能向吸气管道流过，不存在 重复吸入问题。
4.呼气通道内有呼气单向阀，病人不可能重复吸入呼出气，同时还提高同步触发灵敏度。因为病人的吸气努力全部通过吸气管道传到呼吸机，而不是部分。
5.可以在呼吸阀部位输入氧气，因为很少或者不存在泄漏，氧气的消耗和浪费少。氧浓度也容易计算和控制。
6.氧流量兼有基础流量功能，可提高通气效率。
7.由于流过管道的流量接近于病人的分钟通气量，接入湿化器后对吸入气体的加温加湿比双气压呼吸机效果明显提高。

具体实施方式
以下结合附图来说明本发明的具体实施方式。
<实施例一>
如图1和图2所示，提高双气压呼吸机性能的呼吸阀，包括：吸气阀盖1、呼气阀盖9、膜片5、吸气单向阀3、吸气单向阀座4、呼气阀口6、呼气单向阀片7以及呼气单向阀座8。
吸气阀盖1和呼气阀盖9相互扣合。
吸气阀盖1具有呼吸机接口21，用于连接双气压呼吸机。吸气阀盖 1上还具有加氧接口10，可以从此处进行加氧。
如图5所示，吸气阀盖1具有吸气管道接口13，可连接从病人来的管道；为了长期稳定的性能，安排有积水排出口。病人呼出气可以在排气口收集。
膜片5，设置在吸气阀盖1和呼气阀盖9的中间，膜片5与吸气阀盖1所围成的内部空间称为吸气阀腔，膜片5与呼气阀盖9所围成的内部空间称为呼气阀腔。
膜片5具有弹性，包括：阀片51，膜片本体52，固定边缘53，柔性边缘54。膜片本体52为圆形，阀片51设置在膜片本体52的中央，柔性边缘54环绕膜片本体52一周。固定边缘53，当吸气阀盖1和呼气阀盖9相互扣合时，夹住固定边缘53，从而将膜片5固定住。
吸气单向阀3，防止病人呼出气进入吸气管道，设置在吸气阀腔中。
吸气单向阀座4，设置在吸气单向阀3的后面。
呼气阀口6，设置在呼气阀腔中。
呼气单向阀片7，设置在呼气阀口6的后面。
当呼气阀腔压力低于吸气阀腔时，膜片5向呼气阀口6方向运动，封闭呼气阀口6。呼气单向阀片7，是病人呼出气的通道。还可提高同步触发灵敏度，同时病人吸气时不会从呼气管道重复吸入已经呼出的气体。
呼气单向阀座8，支撑呼气单向阀片7。呼气阀口6从呼气单向阀片7和呼气单向阀座8的中央的孔穿过。其他实施时可以使用其他类型的单向阀。
氧气单向阀2，与加氧接口10相连接。不连接氧气时防止泄漏。在 其它的实施方式中，也可在加氧接口10处加塞子来防止泄漏。
积水排放口11，设置在呼气阀盖9上。
呼气管道接口14，设置在呼气阀盖9上。用于连接来自病人方向的呼气管道。
呼出口12，设置在呼气阀盖9上。
当进行吸气时，气体从呼吸机进入，然后经吸气单向阀3和吸气单向阀座4进入到吸气阀腔，然后从吸气管道接口13中进入到吸气管路19中。此时，吸气阀腔中的压力大于呼气阀腔的压力，膜片向呼气阀口6方向运动，并将呼气阀封闭。当进行呼气时，双气压呼吸机提供的压力下降，使得吸气阀腔压力低于呼气阀腔，呼气阀打开，呼出的气体从呼气管道接口14进入到呼气阀腔，然后经过呼气单向阀座8和呼气单向阀片7进入到呼出口12中排出。此时吸气单向阀3在气压的作用下处于关闭状态，从而防止病人呼出气进入吸气管道。
<实施例二>
本实施方式提供一种呼吸装置，包括如实施例一中所描述的呼吸阀。
如图6所示，呼吸装置还包括：吸气管路19、呼气管路16以及Y型接头20。
吸气管路19，一端与呼吸阀的吸气管道接口13相连通，另一端与Y型接头20相连通。
呼气管路16，一端与呼吸阀的呼气管道接口14相连通，另一端与Y型接头20相连通。
湿化器17，设置在吸气管路19上。对流经的气体进行加湿。
第一积水杯18，设置在吸气管路19上。
第二积水杯22，设置在呼气管路上，以减少积水排放口11处的积水。
