技术领域
本发明涉及人体呼吸调节技术,尤其涉及一种加湿装置、湿化器及呼吸机。
背景技术
呼吸机的湿化器主要用来增加输送给患者的气体的湿度。用于医疗目的的气体,通常不包含充足的水分,直接使用会损伤或刺激到用户的呼吸道或上呼吸道,也容易使得用户的呼吸道或者上呼吸道被旁路患者分泌物干稠,并因此可能导致气道缩窄甚至阻塞。对湿化器中提供的水分进行加热,可以增加湿化器的水汽输出。
目前的湿化器的加湿装置,基本都是将储水区和加热区集中在一个腔体中。使用时,在加湿装置中加入足够一定时间消耗的水量,通过呼吸机工作的气流以及加热,慢慢地将水份带给患者使用。
由于加湿装置中需要储备足够一定时间消耗的水量,所以一开始加湿装置中的水量必然会较多。这就容易导致呼吸机刚开始工作时加热效率低、加热时间长。
发明内容
本发明所要解决的技术问题是为了克服现有技术中的呼吸机在加湿装置中水量较足时加热效率较低等不足。
为了解决上述技术问题,本发明的实施例首先提供了一种加湿装置,包括加热区以及向所述加热区输送液体的液体输送装置,所述液体输送装置包括进液管道,所述进液管道伸入在所述加热区中并向所述加热区的底部延伸,所述进液管 道的出口与所述加热区的底部之间具有预留间距。
优选地,所述液体输送装置还包括出气管道,所述进液管道的入口低于所述出气管道的出口,所述进液管道的出口低于所述出气管道的入口,所述进液管道的出口与所述出气管道的入口均伸入在所述加热区中。
优选地,所述液体输送装置还包括设置在所述加热区中的悬浮密封件,所述悬浮密封件对着所述进液管道的出口且在所述加热区中的液体的浮力作用下可以堵住所述进液管道的出口。
优选地,所述悬浮密封件包括基础部和设置于所述基础部上的密封部,所述密封部与所述进液管道的出口相配合。
优选地,所述密封部至少部分地位于所述进液管道的出口中。
优选地,所述液体输送装置还包括设置在所述加热区中的弹性密封件,所述弹性密封件对着所述进液管道的出口且在气体的压力作用下可以打开所述进液管道的出口。
优选地,所述弹性密封件包含密封板和设置在所述密封板底部的弹性件;所述密封板上朝向所述进液管道的出口设置有密封体,所述密封体与所述进液管道的出口相配合。
优选地,所述加湿装置还包括与所述液体输送装置相连的储液区,所述进液管道的入口与所述储液区相连。
本发明还提供了一种湿化器,包括加热件以及如上所述的加湿装置,所述加热件对所述加湿装置的加热区中的液体进行加热。
本发明还提供了一种呼吸机,包括主机以及如上所述的湿化器,所述主机与所述加热区的进气口相连,可连接至人体的管道与所述加热区的出气口相连。
与现有技术相比,本发明的实施例通过将进液管道的出口与加热区的底部留有预留间距,使得加热区中的液体的液面不会超过进液管道的出口,从而能够避免加热区中的水较多导致加热效率低的现象;并且该加湿装置能够实现动态补水,保证加热区中的液体量恒定,避免干烧。
本发明的实施例通过更换或者往储液区中补充液体就可以实现对加湿装置的液体补充操作,避免了液体添加过程中需要频繁开合湿化器,从而使用起来非常便利高效。而且液体添加过程中加热件不会裸露,不会发生患者被烫伤的危险。
本发明的其它特征和优点将在随后的说明书中阐述,并且,部分地从说明书 中变得显而易见,或者通过实施本发明的技术方案而了解。本发明的目的和其他优点可通过在说明书、权利要求书以及附图中所特别指出的结构和/或流程来实现和获得。

图2为本发明的加湿装置的第二实施例的构造示意图。
图3为本发明的加湿装置的第三实施例的构造示意图。
图4为本发明的加湿装置的第四实施例的构造示意图。
具体实施方式
以下将结合附图及实施例来详细说明本发明的实施方式,借此对本发明如何应用技术手段来解决技术问题,并达成相应技术效果的实现过程能充分理解并据以实施。本发明实施例以及实施例中的各个特征,在不相冲突前提下可以相互结合,所形成的技术方案均在本发明的保护范围之内。
本发明的发明人在实现本发明的过程中,还发现了现有的加湿装置在开机应用时,需要对整个加湿装置中的液体进行加热,这就存在加热时间长、加热效率低的不足。而且,即便一开始给加湿装置中储备足够量的液体,在使用一段时间后,仍然需要给加湿装置进行补充液体。长时间使用呼吸机的话,就需要频繁开合湿化器将加湿装置取出、补充液体之后又放入到湿化器中。而且,在将加湿装置取出加液体时,会裸露湿化器下端的加热底板,这有可能导致患者或者其他人员被烫伤,安全性也较低。
如图1所示,本发明的加湿装置的实施例,包括加热区3以及向加热区3输送液体(比如水或者水溶液等)的液体输送装置2,该液体输送装置2还可以将加热区3中的液体维持在预设体积。液体输送装置2包括进液管道21,进液管道21伸入在加热区3中并向加热区3的底部延伸。进液管道21位于加热区3中的出口20与加热区3的底部之间具有预留间距,使得液体从进液管道21进入到加 热区3中时,加热区3内的液面上升到进液管道21的开口20(至少与进液管道21的出口20平齐),进液管道21内的液体停止进入到加热区3内。进液管道21可以是直的,也可以是弯曲的。
如图1所示,本发明的加湿装置的实施例,还可以包括有储液区1。具有开口的储液区1与液体输送装置2可拆卸地相连接,并通过液体输送装置2与加热区3相连通。较优地,储液区1与液体输送装置2通过相对设置的开口相连接,储液区1的开口较小而液体输送装置2的开口较大,在配合使用时储液区1的开口套在液体输送装置2的开口中,并且储液区1与液体输送装置2通过螺纹连接的方式连接在一起。或者,储液区1的开口也可以直接套在液体输送装置2的开口中。如图1所示,盛有水的储液区1以倒插的方式,将开口插入在液体输送装置2的开口中。
进液管道21位于加热区3中的出口20与加热区3的底面之间预留有间距,与加热区3的底面不接触,便于液体输送装置2中的液体能从进液管道21的出口20进入到加热区3中。一般地,预留间距大于5mm且小于30mm。预留间距大于5mm,能够使得进液管道21内的液体顺利流出;预留间距小于30mm,是为了减少加热区内的液体的液体量,使得在同样功率的加热条件下,加热区内的液体蒸发更快,加湿效果更好。优选地,当液体为水时,预留间距为10mm或15mm,能使得加湿效果最好。
图1所示的实施例中,进液管道21的出口20设置在位于加热区3中的端部。在其他实施例中,出口20也可以设置在进液管道21位于加热区3中的其他部位上而非端部。
储液区1中的液体通过液体输送装置2,在重力作用下,可以流入加热区3中。加热区3上设置有进气口31和出气口32。进气口31引导外部的气体(从呼吸机中输出的气体)进入到加热区3中加湿,加湿之后的气体通过出气口32进入到连接至用户鼻腔和/或口腔的管道中输送给用户。图1中的箭头表示出了气体从进气口31进入、经过加热区3并从出气口32流出的气流方向。
本发明的加湿装置的实施例在应用时,储液区1中的液体经液体输送装置2进入到加热区3中,同时加热区3中的空气通过液体输送装置2进入到储液区1中,从而储液区1中的液体可以在重力作用下自动进入到加热区3中。随着储液区1中的液体不断地进入到加热区3中,加热区3中的液面就会逐渐上升。在加 热区3中的液面上升到没过液体输送装置2位于加热区3中的进液管道21的出口20(加热区3中的液面至少与进液管道21的出口20相平齐)时,加热区3中的空气就无法通过液体输送装置2继续进入到储液区1中,从而,储液区1中的液体就不能继续往加热区3中补充,加热区3中的液体得以维持在预设体积。直到加热区3中的液体经过加热后随气体一起经出气口32输送给用户而使得加热区3的液体产生消耗时,加热区3中的液面与液体输送装置2位于加热区3中的出口20之间产生的缝隙允许空气进入到液体输送装置2并最终到达储液区1时,储液区1中的液体在重力作用下就会继续向加热区3中进行补充。也即,储液区1中的液体在向加热区3中进行补充时,是一个动态的平衡过程。
储液区1、液体输送装置2以及加热区3形成的内部空间是密闭的。在加热区3中无液体或者加热区3中的液面低于进液管道21的出口20时,在重力以及大气压强的作用下,储液区1中的液体会经过液体输送装置2进入到加热区3中。当储液区1中的液体通过液体输送装置2源源不断地补充到加热区3中,使得加热区3中的液面逐渐上升到没过进液管道21的出口20(加热区3中的液面至少与进液管道21的出口20相平齐)时,储液区1中的液体在大气压强的作用下,会停止向加热区3中流动,加热区3中的液体得以维持在预设体积。随着加热区3中的液体的消耗(跟随进入到加热区3中的气体一起通过出气口32进入到连接至用户鼻腔和/或口腔的管道中),加热区3中的液面低于进液管道21的出口20时,储液区1中的液体就会在重力作用下向加热区3中进行补充,直至加热区3中的液体面没过进液管道21的出口20或者储液区1中的液体消耗完。
本发明的实施例中,进液管道21的出口20,截面可为圆形或者椭圆形,也可以为三角形、矩形等多边形,还可以是不规则外形。为保证液体输送装置2可以顺畅、及时地为加热区3补液体,本发明的一些实施例中,进液管道21的出口20的截面积大于7平方毫米(mm2)。
如图1所示的实施例,当加热区3中的液面下降,或者一开始加热区3中没有液体的情况下,储液区1中的液体通过液体输送装置2进入到加热区3中时,加热区3中的气体需要经过液体输送装置2反向地从加热区3进入到储液区1中。这种情况下,气体就会以气泡的方式向上进入到储液区1中,储液区1中的液体伴随“咕嘟咕嘟”的声响进入到加热区3中。
图2示出了本发明的加湿装置的第二个实施例。如图2所示,液体输送装置 2包含有进液管道21和出气管道22。进液管道21被设置为将储液区1中的液体输送到加热区3中,出气管道22被设置为将加热区3中的气体输送到储液区1中。进液管道21的出口211与出气管道22的入口221均伸入在加热区3中,而且进液管道21的入口212低于出气管道22的出口222,进液管道21的出口211低于出气管道的入口221,比出气管道的入口221更靠近加热区3的底部。出气管道22可以是直的,也可以是弯曲的。
如图2所示的实施例在使用时,储液区1中的液面低于出气管道22在储液区1中的出口222时,储液区1中的液体就可以通过进液管道21进入到加热区3中,加热区3中的气体就可以从出气管道22进入储液区1中,以此来保持储液区1与加热区3中的压力平衡。当从加热区3中被带走的水份导致加热区3中的水量减少,液面低于出气管道22在加热区3中入口221时,加热区3中的气体就会经过出气管道22进入到储液区1中,储液区1中的液体就会经过进液管道21流到加热区3中,加热区3中的液面上涨至没过出气管道22的入口221(加热区3中的液面至少与出气管道22的入口221平齐),此时储液区1中的液体就会停止向加热区3中进行补充,加热区3中的液体得以维持在预设体积。通过这种结构对加热区3进行补液体时,液体从进液管道21传输到加热区3,气体从出气管道22传输到储液区1,而且出气管道22位于储液区的出口222高出储液区1的液面,因此储液区1中的液体不会发出“咕嘟咕嘟”的声响,使用更加安静。
当然,在储液区1中的液体量较多而使得使用状态下储液区1中的液面不低于出气管道22在储液区1中的出口222时,储液区1中的液体可以通过进液管道21和出气管道22进入到加热区3中。在这种情况下,加热区3中的气体,通过出气管道22进入到储液区1中。
当加热区3中的液面没过出气管道22在加热区3中的入口221时,储液区1中的液体就停止通过进液管道21流入加热区3,加热区3中的液体得以维持在预设体积。
图3示出了本发明的加湿装置的第三个实施例。在图3所示的实施例中,加热区3中设置有可以堵住液体输送装置2中进液管道21位于加热区3中的出口20的悬浮密封件5。悬浮密封件5的密度比液体的密度小,被设置在正对着进液管道21的出口20。
当加热区3中没有液体时,悬浮密封件5与加热区3的底面接触,且与进液管道21的出口20脱开不密封。从而储液区1中的液体可以经过进液管道21流入到加热区3中。随着水不断地进入加热区3,密度比水液体的悬浮密封件5随着液面逐渐上升,直至将进液管道21的出口20密封住,阻断储液区1中的液体继续流入加热区3中。当加热区3中的液体量随着使用逐渐减少时,悬浮密封件5又随液位逐渐下降,此时悬浮密封件5又与进液管道21的出口20脱开不密封,储液区1中的液体再次流入加热区3。
为保证悬浮密封件5能够密封住进液管道21的出口20,悬浮密封件5朝向储液区1的顶部设置有密封结构,以与进液管道21的出口20相对应。
如图3所示,悬浮密封件5包括基础部51和基础部51上的密封部52(即前述的密封结构)。在使用时,密封部52被套设在进液管道21的出口20之内,或者至少密封部52的一部分被套设在进液管道21的出口20之内。密封部52的外部形状,与进液管道21的出口20的内部形状相配合。比如,进液管道21的出口20设置为圆形时,悬浮密封件5上对应设置有球冠这种球面密封部。当加热区3中的液面托着悬浮密封件5密封住进液管道21的出口20时,悬浮密封件5上的球冠刚好堵住进液管道21圆形的出口20。
较优地,本发明的实施例中,悬浮密封件5的整体高度,也即基础部51的高度与密封部52的高度之和,大于进液管道21的出口20到加热区3的底面距离。而且,悬浮密封件5的基础部51的高度,小于进液管道21的出口20到加热区3的底面距离。这样,密封部52至少部分地位于进液管道21的出口20中,保证了悬浮密封件5上的密封部52始终位于进液管道21的出口20之内而不会脱出。使得无论加热区3中是否有液体,以及有液体时液位的高低,悬浮密封件5均只会与进液管道21产生一段间隙而不会完全脱开,避免由于加热区3中缺液体时悬浮密封件5从进液管道21的出口20完全脱开而后续加热区3中有液体时不能对进液管道21的出口20进行密封。
图4示出了本发明的加湿装置的第四个实施例。
如图4所示,本发明的加湿装置的实施例中,加热区3在位于液体输送装置2的进液管道21的出口20的下方,设置有可以堵住进液管道21的出口29的弹性密封件6。该弹性密封件6包含有密封板61和设置在所述密封板底部的弹性件62,密封板61朝向进液管道21的出口29,弹性件62顶抵在密封板61的底部和 加热区3的底部之间。密封板61上设置有密封体610,该密封体610的外部形状与进液管道21的出口20的内部形状相配合,使得该密封体610能够堵住进液管道21的出口20。该弹性件62比如可以是弹簧。
加热区3对应于弹性密封件6设置有腔体33,弹性密封件6中的密封板61与该腔体33相配合,弹性件62设置在腔体33中。在加热区3内没有气体进入时,在弹簧的作用下,密封板61上的密封体610顶在进液管道21的出口20中,将储液区1和加热区3隔开。
当呼吸机开始工作时,呼吸机产生的气体通过加热区3带着湿润的气体给患者,气体进入加热区3时,主要会从密封板61朝向进液管道21的出口20的一侧通过,从而就会将密封板61向下压,弹簧受力压缩,带着密封板61上的密封体610与进液管道21的出口20脱开,进液管道21中的水即进入加热区3中。在密封板61的密度小于液体的密度时,随着液体不断地进入加热区3,密封板61也随着液面逐渐上升,直至将进液管道21的出口20密封住,阻断储液区1中的液体继续流入加热区3中;当加热区3中的液体量随着使用逐渐减少时,弹性密封件6又随液位逐渐下降,此时弹性密封件6又与进液管道21的出口20脱开不密封,储液区1中的液体再次流入加热区3。当密封板61的密度大于液体的密度时,加热区3中的液面即将没过但还未没过密封板61时,在液体的浮力以及弹簧回复自由状态的共同作用下,就会带动密封板61堵住进液管道21的出口20,储液区1中的液体就会停止向加热区3中进行补充。
本发明的实施例将湿化器的加湿装置分为储液区和加热区两个腔体,通过液体输送装置将储液区和加热区连通,并用液体输送装置中的进液管道上的出口与加热区底面之间的距离来控制加热区中的液面高度,从而减少了加热区中的总液体量来提高加热效率和缩短加热时间。
本发明加湿装置的实施例通过更换储液区或者将储液区取下后往其中加液体的操作,就可以实现加液体操作,不需要将液体输送装置、加热区以及加热件等一起取出,避免了加液体过程中需要频繁开合湿化器,从而使用起来非常便利高效。在取下储液区往其中加液体或者直接更换储液区的作业过程中,加热区中仍然可以存储有一定量的水用于对气体进行加湿,不会出现干烧的现象,不会因没有及时加液体而导致设备过热的危险发生。而且加水过程中加热件不会裸露,不会发生患者被烫伤的危险。
需要说明的是,本发明的实施例中,在流体输送装置2的连通及流体(包括液体和气体)流动的控制作用下,储液区1中的液体和气体,与加热区3中的液体和气体,维持着一个动态的平衡。随着加热区3中的水逐渐被消耗,储液区1中的液体就会源源不断地补充到加热区3中,直至储液区1中的液体被消耗完。当然,在储液区1中的液体被消耗完之前,用户可以更换储液区1或者取下储液区1并往其中加液体之后继续使用。
以上实施例中,加热区3的进气口31和出气口32的压力相对恒定,使得加热区3内的气压相对恒定。另外,需要说明的是,在进气口31和出气口32的压力恒定的状态下,储液区1、加热区3以及液体输送装置2为一个密封体,在进液管道21的出口20与加热区3的底部之间具有预留间距,使得液体从进液管道21进入到加热区3中时,加热区3内的液面上升到进液管道21的开口20(至少与进液管道21的出口20平齐),进液管道21内的液体停止进入到加热区3内。
本发明的湿化器的实施例,包括加热件以及上述实施例所给出的加湿装置。加热件主要被设置为对加热区3中的液体进行加热。如图1所示,较佳地,加热件位于加热区3的底部,这样加热区3中的水的受热可以更加均匀。加热件设置为产生热量,以对加热区3中的液体进行加热。如图1所示,本发明的湿化器的实施例中,加热件被设置为位于加热区3的底部并于加热区3的底部直接接触的加热底板4。相应地,加热区3的底部具有良好的导热性,可以高效率地将加热件所产生的热量传导至加热区3内所盛装的液体。这样设置的加热件以及相应的加热区3,可以保证较高的加热效率。
本发明的呼吸机的实施例,包括主机以及上述的湿化器。主机与加热区上的进气口相连,连接至人体的管道与加热区的出气口相连。
本发明的湿化器和呼吸机的实施例,还请参照图1至图4所示的本发明的加湿装置及其中的液体输送装置的结构和相应的说明,此处不再赘述。
虽然本发明所揭露的实施方式如上,但所述的内容仅为便于理解本发明技术方案而采用的实施方式,并非用以限定本发明。任何本发明所属领域内的技术人员,在不脱离本发明所揭露的精神和范围的前提下,可以在实施的形式及细节上进行任何的修改与变化,但本发明的专利保护范围,仍须以所附的权利要求书所界定的范围为准。
