Description

一种加温加湿器及其加温加湿方法 技术领域
本发明涉及医疗设备配件的技术领域，特别是一种加温加湿器及其加温加湿方法。
背景技术
在呼吸科的临床治疗中，呼吸机是常用的医疗器械。由于从呼吸机里出来的气体是干冷的，人体如果直接吸入这种干冷的气体会造成呼吸道失水，粘膜干燥，纤毛运动抑制或丧失，分泌物变得黏稠从而形成痰痂，会引起排痰不畅，气管堵塞继发感染。因此需要对呼吸机里出来的气体进行加温加湿。传统的加温湿化器包括中空的壳体，壳体内盛装医用蒸馏水，壳体内部或底部设置有加热装置，壳体上部设置进气管和出气管，进气管和出气管都高悬于液面之上。从呼吸机里出来的气体通过进气管进入壳体内部，与加热后产生的水蒸气混合湿化后通过出气管排出---蒸气加湿法。
这种加温加湿方法有很多缺陷：
1、湿化系统的输出量不好控制(单位时间内输出的水汽含量mg/l)：此种方式水汽的产生主要靠加热板加热水罐，使水罐里的水蒸发而产生水汽，蒸发量取决于加热底板的温度、加热底板与水罐的接触面积、水罐材料的导热性能等诸多因素；
2、控制精度不够、响应时间长：由于蒸发量是由水温、罐体内压力决定的，水温高蒸发量大，水温低则蒸发量小。而水的温度是由加热底板传导给水罐，再由水罐传导给水，其热传导过程中有大量损失不说，而且热传导响应时间长，不利于精确实时的控制温湿度。
3、管路中冷凝水严重：由于蒸汽加热的机理，在水罐出口处气体处于过饱 和状态。如果是普通管路，要使得到达人体端的气体温度达到37℃，则气体在水罐出口处需达到较高温度，气体在管道中从较高温度降低到37℃的降温过程中将产生大量冷凝水而影响患者安全。如果匹配加热管路，虽然可以减少冷凝水的产生，但不改变其气体在管道运动过程中由过饱和变为饱和状态时析出冷凝水的本质。
4、设备太大，太重不利于放置搬运，增加医生操作难度。
发明内容
为解决上述问题，本发明的目的是提供一种自动补水雾化、呼吸气体预热后与水雾结合、水雾汽化后输出、通过加热管路输送到病患，输送过程实时监控温湿度、到达管路的病患端时处于一个适宜的温度及接近饱和相对湿度的气体、实时反馈调整保温输出使用、加湿量控制精度高、加温时间短、管路中不会产生冷凝水的加温加湿器及其加温加湿方法。

蒸气发生器为内外两层隔层设计，蒸气发生器的蒸发室一侧开通，且蒸发室内底部环形设有内室片，内室片在蒸发室开口一侧设有过气口，蒸发室上连 通有进气口，内室片上连通有出气口，蒸发室开通一侧设有端盖，端盖上设有插口，端盖一侧设有加热装置；
蒸气发生器出气口与加热呼吸管路的管体的近端的快速接头连接，加热呼吸管路远端的Y接头与病患者相连，管体设有加热线，快速接头与Y接头上设有温湿度监测孔，温湿度监测孔分别与外壳内的控制器上的温湿度传感器相连。
作为优选，所述的罐盖下方的止水柱内壁环形设有加厚台阶，止水柱下方设有环形片，环形片内孔处开有齿口，漂浮上盖的套柱上设有两与齿口对应的限位齿，套柱上端设有顶头，顶头上方垫有缓冲垫，套柱上的限位齿穿过齿口后置于环形片与加厚台阶之间。
作为优选，所述的蒸发室置于外壳开口处的两夹片间，蒸发室两侧设有扣片，扣片通过其上的扣齿二与外壳上两侧卡槽上的扣齿一扣接，且蒸发室置于外壳内，内室片端部边缘与端盖上的槽口扣接，加热装置置于内室片内，内室片两侧与蒸发室之间均设有隔离片，隔离片在蒸发室底面位置设有通过口，蒸发室底面为中空设计。
作为优选，所述的外壳内对称式设有限位片，限位片上对称式设有卡口，两限位片之间设有缺口，罐体的出雾口置于缺口内，接线部位两侧与限位片上的卡口扣接，接线部位与端盖上的插口对接，加热装置连接端盖上的插口。
作为优选，所述的外壳上设有若干圆孔，外壳内的控制器上的电源接头、接线插头均置于圆孔内，加热线、加热装置、雾化片、温湿度传感器均通过连接线与控制器连接，接线部位通过连接线与控制器连接。

(2)水雾气化：将呼吸使用的气体通过进气口通入，经过蒸发室与内室片之间隔层，首先对气体进行预热，再从端盖一侧的过气口处进入内室片内部，即可直接与雾化片雾化的小水珠颗粒一同向出气口方向运动，运动同时通过加热装置对水雾和气体进行加温，加热水雾至完全气化，获得高于常温的不饱和蒸气，使得出气口28的水蒸气处于不饱和状态；
(3)保温出气：从出气口输出的气体通过管体输送，输送过程中受环境温度的影响，通过加热线可进行补热输送，从Y接头输出后即可给使用者使用，在温度降低时气体的绝对湿度不变，相对湿度逐渐升高，在到达病患端时其相对湿度接近饱和，因气体在运动过程中是由不饱和状态逐步变为接近饱和状态，不会产生冷凝水，从而控制管体中冷凝水的产生，快速接头与Y接头上温湿度监测孔的设计，可实时反馈水气温度与湿度，从而利用控制器控制管体上加热线的功率、雾化片的雾化量与加热装置的功率，得到温湿度合适气体。
本发明的有益条件在于：

3、蒸气发生器为内外两层隔层设计，呼吸用气体由进气口进入后通过蒸发室与内室片之间的隔层进行预热后，再从过气口进入内室片内腔，从而与加热气化的水雾结合，形成高于常温的不饱和水汽从出气口输出，不产生冷凝水；
4、快速接头与Y接头出温湿度检测孔的设计，实时监测温湿度，从而利用控制器控制管体内加热线的温度、雾化片的雾化量与加热装置的温度，得到合适呼吸的水气。

具体实施方式
如图1、2、3、4所示，一种加温加湿器，包括外壳1、水罐雾化组、蒸气发生器、加热呼吸管路、控制器，所述的水罐雾化组的罐体11通过其外侧壁的扣条与外壳内的若干弹片5扣接，蒸气发生器通过两侧的扣片29与外壳1两侧的卡槽8扣接，水罐雾化组的罐体11上的出雾口13与蒸气发生器接口38对接，蒸气发生器上的出气口28连接加热呼吸管路；
罐体11一侧的凸条12与外壳1上的扣槽2扣接，出雾口13端部外侧套接有密封圈，其内套接有雾化片14，雾化片14一侧垫有顶块，罐体11上螺纹连 接有罐盖15，罐盖15下表面设有止水柱16，补水管18穿过罐盖15后与止水柱16连通，漂浮上盖19上的套柱20与止水柱16套接，漂浮上盖19下设有漂浮下盖23；
蒸气发生器为内外两层隔层设计，蒸气发生器的蒸发室24一侧开通，且蒸发室24内底部环形设有内室片25，内室片25在蒸发室24开口一侧设有过气口26，蒸发室24上连通有进气口27，内室片25上连通有出气口28，蒸发室24开通一侧设有端盖30，端盖30上设有插口31，端盖30一侧设有加热装置32；

所述的罐盖15下方的止水柱16内壁环形设有加厚台阶17，止水柱16下方设有环形片，环形片内孔处开有齿口，漂浮上盖19的套柱20上设有两与齿口对应的限位齿21，套柱20上端设有顶头22，顶头22上方垫有缓冲垫，套柱20上的限位齿21穿过齿口后置于环形片与加厚台阶17之间。所述的蒸发室24置于外壳1开口6处的两夹片7间，蒸发室24两侧设有扣片29，扣片29通过其上的扣齿二与外壳1上两侧卡槽8上的扣齿一扣接，且蒸发室24置于外壳1内，内室片25端部边缘与端盖30上的槽口扣接，加热装置32置于内室片25内，内室片25两侧与蒸发室24之间均设有隔离片，隔离片在蒸发室24底面位置设有通过口，蒸发室24底面为中空设计。所述的外壳1内对称式设有限位片3，限位片3上对称式设有卡口4，两限位片3之间设有缺口，罐体11的出雾口13置于缺口内，接线部位33两侧与限位片3上的卡口4扣接，接线部位33与端盖30上的插口31对接，加热装置32连接端盖30上的插口31。所述的外壳1 上设有若干圆孔10，外壳1内的控制器上的电源接头、接线插头均置于圆孔10内，加热线、加热装置32、雾化片14、温湿度传感器均通过连接线与控制器连接，接线部位33通过连接线与控制器连接。所述的外壳1上边缘通过卡扣扣接有上盖9。所述的接口38套接于出雾口13端部，且出雾口13上环形设有台阶，密封圈设于台阶与接口38之间。所述的加热装置32为呈螺旋形的加热丝。所述的管体34上的加热线可设置于管体34内、可缠绕于管体34外壁凹陷槽内或垫于内模与凸出筋之间。
一种加温加湿器的加温加湿方法，具体步骤如下：(1)注水雾化：通过补水管18对罐体11进行充水，直至水顶起浮漂上盖19至顶头22进入加厚台阶17内利用缓冲垫顶紧补水管18端部，停止加水，同时补水管18可连接至水袋，水进入出雾口13，利用雾化片14将水雾化成小水珠颗粒进入内室片25；(2)水雾气化：将呼吸使用的气体通过进气口27通入，经过蒸发室24与内室片25之间隔层，首先对气体进行预热，再从端盖30一侧的过气口26处进入内室片25内部，即可直接与雾化片14雾化的小水珠颗粒一同向出气口28方向运动，运动同时通过加热装置32对水雾和气体进行加温，加热水雾至完全气化，获得高于常温的不饱和蒸气，使得出气口28的水蒸气处于不饱和状态；(3)保温出气：从出气口28输出的气体通过管体34输送，输送过程中受环境温度的影响，通过加热线可进行补热输送，从Y接头36输出后即可给使用者使用，在温度降低时气体的绝对湿度不变，相对湿度逐渐升高，在到达病患端时其相对湿度接近饱和，因气体在运动过程中是由不饱和状态逐步变为接近饱和状态，不会产生冷凝水，从而控制管体34中冷凝水的产生，快速接头35与Y接头36上温湿度监测孔37的设计，可实时反馈水气温度与湿度，从而利用控制器控制管体34上加热线的功率、雾化片14的雾化量与加热装置32的功率，得到温湿度合适 气体。
本发明的罐体11通过弹片5扣接、凸条12与扣槽2限位，进行对接，蒸气发生器插入式放入外壳1的开口6，通过两夹片7夹紧后，利用扣片29与卡槽8扣接连接，拆装方便，漂浮上盖19上套柱20上的限位齿21与止水柱16上环形片的齿口套接，防止无水时掉落，且罐体11内水满后可推动套柱20上方的缓冲头22顶紧补水管18，实现缺水补水、水满止水，蒸发室24与内室片25之间存在空隙，所述的内室片25两侧与蒸发室24之间均设有隔离片，隔离片在蒸发室24底面位置设有通过口，由于内室片25内具有温度，呼吸用气体可从蒸发室24与内室片25之间隔层预热，且呈U字形运动的气体预热效果更佳，蒸发室24底面为中空设计，隔热效果好防止烫伤，再从过气口26进入内室片25，即可与未气化的雾气结合，逐渐向出气口28移动，过程中会经过加热装置32，从而雾气被气化，得到的水蒸气为不饱和状态下从出气口28输出，管体34的快速接头35与Y接头36出温湿度检测孔37的设计，实时监测温湿度，从而利用控制器控制管体34上加热线的功率、雾化片14的雾化量与加热装置32的功率，得到温湿度合适呼吸的气体；
通过加温加湿器的加湿方法，通过蒸气发生器加热水雾直至完全汽化，这种方式的优点是水雾的相对受热面积大，受热均匀，汽化过程快，同时加湿量是通过雾化片14控制，精度高，起到给管路中的气体加温加湿的目的。蒸气发生器出气口28的气体温度高于常温、且相对湿度较低，处于不饱和状态，被加温加湿后的管体34中的气体绝对湿度基本不会发生变化，但水蒸气运行是一个温度逐步降低、同时相对湿度不断提高的过程。因为在管体34的进气端的气体的湿度是处于不饱和状态，随着管体34中气体温度逐步下降，相对湿度会逐步提高，通过控制管体34进气端和出气端的温度的差值，保证管体出气端的相对 湿度接近饱和状态，整个过程管体34中的气体的湿度均处于不饱和的状态，故不会有冷凝水产生。
本行业的技术人员应该了解，本发明不受上述实施例的限制，上述实施例和说明书中描述的只是说明本发明的原理，在不脱离本发明精神和范围的前提下，本发明还会有各种变化和改进，这些变化和改进都落入要求保护的本发明范围内。本发明要求保护范围由所附的权利要求书及其等效物界定。
