Description

一种湿化罐 技术领域
本申请涉及医疗器械领域，尤其设计一种湿化罐。
背景技术
用于持续气道正压通气治疗的设备通常包括鼓风机，鼓风机的出风口通过呼吸管路连接病人所佩戴的面罩以实现与病人进行空气交互。由于经过加温加湿的空气会令病人在感受上更舒适，也更易接受，因此现有的通气治疗设备都与加湿器装置配合供给病人使用。加湿器装置一般设置在鼓风机出风口与面罩的接口之间，加湿器装置包括湿化罐和加温装置，湿化罐的进风口与鼓风机的出风口连接，湿化罐的出风口与面罩的接口连接，湿化罐内加有一定量的水，由鼓风机进入湿化罐的空气与水接触进行加湿，并经过加温装置进行加温，最终传入面罩中供给病人呼吸。但是，这种将通气治疗设备和加湿器装置直接进行连接的设计会导致由于加湿器装置相对于其正常方位倾转，使的加湿器装置内的水流入鼓风机，从而造成鼓风机损坏甚至引起通气治疗设备的损坏。
为了解决上述问题，通常在鼓风机和湿化罐之间设置长的进气管，并且在进气管口设置防逆槽，以防止湿化罐内的水流入鼓风机。但是，这种实现方式并不能实现全面防逆流，如图1所示，防逆槽虽然会将加湿过程中产生的附着在进气管上的加湿气体，以及，由于大幅晃动湿化罐造成的湿化罐内的水流入至进气管中的水导出到其他地方，而不进入风机中，但是，被导流出去的水往往会流入至呼吸机的机身中，此外，单腔室的湿化罐的防逆流仅仅是单方向的，而不能实现两个方向晃动的防逆流，在晃动的过程中，水不可避免的会通过进气管流入至呼吸机中，造成故障或者用户体验变差，同时使用场景比较单一，不适合在运输过程中，不规则晃动的状态下使用。

本申请提供了一种湿化罐，可以防止湿化罐内的水通过进气口逆流回呼吸机主机中，保证呼吸机主机的安全，此外，本申请提供的湿化罐在两个对向角度晃动时，也能防止湿化罐中的水逆流回呼吸机主机。
参见图1，为本申请提供的湿化罐的爆炸结构示意图，如图1所示，本申请提供的湿化罐包括底座3，与底座3活动连接的上盖1，设置在底座3和上盖1之间的分隔件2，底座3和上盖1之间形成容纳湿化液体的储液腔，分隔件2将储液腔分隔成导流腔32和容纳腔31，分隔件2与上盖1之间设置有挡墙13，挡墙13把导流腔32分隔成逆流液体容置腔321和气体导入腔322，逆流液体容置腔321和气体导入腔322位于同一水平高度。
在一些实施例中，上盖1上设置有用户端接口12，用户端接口12与分隔件上的出气口26贯通设置，用户端接口12向下延伸至容纳腔31，形成出气通路，并且将出气通路隔绝于气体导入腔322，出气口26外侧设置有弹性密封圈，弹性密封圈与用户端接口12下缘配合，气体导入腔322内的气体不能通过出气口26进入容纳腔31，同时能保证经过出气口26的气体不会因为缝隙进入气体导入腔322，从而影响气体压力，并且连通容纳腔31，气流通过容纳腔31进行加湿。
进一步如图2所示，为本申请提供的上盖的结构示意图。上盖1上设置有防呆块15，底座3对应的位置设置有防呆凹槽38，防呆块15卡在防呆凹槽38中，防呆块15和防呆凹槽38使得用户在组装过程中不会出现反装的情况，提升用户组装用户体验。
在一些实施例中，挡墙13上设置有缺口131，气流可以通过缺口131进出气体导入腔322。
在一些实施例中，底座3的侧壁上设置有进气口，进气口包括进气口进气端251和进气口出气端252，进气口进气端251设置在底座3的侧壁上，进气口出气端252设置在分隔件2上，进气口进气端251和进气口出气端252通过弯管连接，进气口出气端252设置在气体导入腔322远离挡墙13的缺口131处。进气口出气端252周围设置有挡筋241，挡筋241可以防止水逆流进进气口进气端251，从而逆流到风机。
在一些实施例中，参见图3，为本申请提供的设置缺口的分隔件的结构示意图，分隔件2上还设置有连通导流腔32和容纳腔31的通气口27，通气口27设置在逆流液体容置腔321，并且通气口27设置在原理挡墙13的缺口131处，尽量让从通气口逆流的液体保 持在逆流液体容置腔321，防止逆流液体进入气体导入腔322。
在一些实施例中，气流流向是从进气口进气端251进入，通过弯管从进气口出气端252进入气体导入腔322，进一步的从挡墙13的缺口131进入逆流液体容置腔321，通过通气口27进入容纳腔31，在容纳腔31中经过湿化，并且通过出气口26和用户端接口12输送给用户。
图4为本申请提供的设置挡筋的分隔件结构示意图，如图4所示，挡墙13设置在气体导入腔322周围，挡墙13进一步的可以包括墙体132和挡筋133，墙体132的高度为分隔件2和上盖1之间的垂直高度，挡筋133的高度低于墙体132的高度。缺口131设置在挡筋133处，可以对小部分的逆流水进行阻挡，防止水进入气体导入腔322，让水储存在逆流液体容置腔321。
图5为本申请提供的上盖和分隔件组合结构的示意图，挡墙13设置在分隔件2上，在其他实施方式中，挡墙13亦可以设置在上盖1上，同时还可以拆分，将挡筋133设置在分隔件2上，将墙体132设置在上盖1上。采用分开设计后，挡筋133的围成气体导入腔322的形状，墙体132叠在挡筋133上面，缺口131设置在墙体132上，挡筋133和墙体132的高度和为上盖1到分隔件2的高度。采用不同的设置方法可以解决在制造过程中，制造难度的问题，方便脱模。可以根据选择不同的设置方式。
图6为本申请实施例提供的导流腔底面的结构示意图，导流腔32的底面可以是一个斜面，进气口出气端252设置在斜面的高处，挡墙13设置在斜面低处，这样即使水流进入气体导入腔322，那么也会因为水流重力的原因存在挡墙13处，不会逆流到进气口出气端252.
进一步如图6所示，可以在挡墙13上设置水流孔211，水流孔211设置在挡墙缺口131一侧，水流孔211设置在挡墙13的下部，水流孔211连通气体导入腔322和逆流液体容置腔321，同时水流孔211呈喇叭口状，为喇叭孔，喇叭孔的孔径大的一侧在气体导入腔322一侧，小孔径一侧位于逆流液体容置腔321一侧。这样一般情况下，气流可以通过喇叭孔，降低气阻，同时还能够梳理气流，降低噪音，同时水流不易从逆流液体容置腔321一侧通过水流孔流入气体导入腔322，而可以反向流出，解决了水积在挡墙13处的问题。
以上所述仅为本实用新型的优选例实施方式，并不构成对本实用新型保护范围的限定。任何在本实用新型的精神和原则之内所作的任何修改、等同替换和改进等，均应包含在本实用新型的权利要求保护范围之内。
