Description

一种新型反流式供氧装置 技术领域
本发明涉及一种保健类产品， 尤其涉及一种新型反流式供氧装置。 背景技术
现有技术中传统的供氧罩用于日常生活， 如日常工作和学习中， 也用于医疗中， 这 种供氧罩的结构如图 A和图 B所示，包括，供氧管 A，完全罩住鼻子和嘴的供氧面罩 B， 所述供氧面罩的前侧上部设有出气孔 C， 供氧面罩的两侧还设有可通过吊带将供氧面罩 固定在鼻子和嘴上的吊带固定部件 D， 但是这种供氧罩具有如下缺点：
( 1 ) 这种供氧罩全罩在鼻子和嘴上， 并且需要挂在脖子或头部， 造成人体头部及 其他部分活动不自由；
(2)这种供氧罩采用直喷方式对人体肺部产生剌激， 肺部易产生炎症， 影响健康;
( 3 ) 这种供氧罩上面的出气孔所在的位置， 使得出气和入气混合在一起， 无法快 速的导出呼出的气体， 呼吸不畅并憋闷。
另外， 医疗中还采用氧气管直接插入鼻孔处以供给氧气的方式， 这种方式也是直喷 方式， 与上一种供氧罩一样会对人体肺部产生剌激， 肺部易产生炎症， 影响健康。
上述两种供氧装置更不适合日常中的工作和学习的使用。
因此， 需要提供一种新型的供氧装置， 以克服上述的各种缺陷。 发明内容
本发明的目的在于提供一种新型反流式供氧装置， 以克服上述现有技术中所存在的 缺陷。 该新型反流式供氧装置置于所需的位置， 人体活动自由， 并且该新型反流式供氧 装置采用反流形式形成气团， 而非具有压力的风速， 从出气孔出来的气团无压力， 对人 无直接的剌激作用， 更不会对肺部产生剌激并导致炎症， 而且人呼出的气体能迅速的扩 散， 不会造成呼吸不畅或憋闷。
为了实现上述目的， 本发明采用如下的技术方案：
一种新型反流式供氧装置， 包括供氧管、 与供氧管连通的壳体、 设于所述壳体内的 腔体以及设于所述壳体前侧并具有密集出气孔的出气罩，所述腔体包括相互连通的反流 腔和回流腔， 所述腔体的前侧设有所述具有密集出气孔的出气罩， 以使气体经反流腔反 流并从出气罩出来后形成气团。
进一步的，所述回流腔靠近供氧管的腔体一端，所述反流腔远离供氧管的腔体一端; 所述反流腔和回流腔呈半个心形的形状。
进一步的， 所述具有密集出气孔的出气罩为平板式出气罩或弧面式出气罩， 所述平 板式出气罩或弧面式出气罩上均布有密集的出气孔。
优选的， 所述平板式出气罩上的每个出气孔均为直孔或均为斜孔。
更优选的，所述平板式出气罩上的所有斜孔的中心轴与平板式出气罩所在的平面的 夹角均为锐角， 并且斜孔的斜向角度为斜向靠近供氧管一端的壳体外。
优选的， 所述弧面式出气罩上的每个出气孔均为直孔或均为斜孔。
更优选的， 所述弧面式出气罩上的斜孔的斜向角度为斜向靠近供氧管一端的壳体 外； 即所有斜孔的斜向是从出气罩内表面的右后方延伸到出气罩外表面的左前方的方 向。
当出气孔为直孔时， 是指每个出气孔的中心轴与平板的平面垂直， 或者指每个出气 孔的中心轴与该出气孔中心轴所在弧面位置的切线垂直。
较佳的， 所述腔体的反流腔和回流腔之间的腔体部分呈圆柱形或椭圆形。
上述的壳体外形呈圆柱形， 椭圆柱形或立体长方形等各种尺寸均可， 只要其内部的 腔体具有上述的所描述的形状， 并使得从出气孔出来的气体形成气团即可。
本发明的新型反流式供氧装置，氧气或具有一定氧气含量的空气从供氧管进入腔体 内，由于气体具有一定的压力，该气体经远离供氧管的腔体一端的反流腔的反流缓冲后， 气体受到反流腔的半心形形状的弧形壁缓冲作用，之后部分气体进一步经壳体内腔体的 后侧壁的阻挡缓冲， 当然另一部分气体经反流腔的半心形形状的弧形壁缓冲作用之后进 入回流腔， 受到回流腔的半心形形状的弧形壁缓冲作用 （当然有很少一部分气体经回流 腔之后随进气在此进入上述的循环）， 这两部分由具有一定压力的气体缓冲后， 经出气 罩的出气孔释放出来， 形成无压力的气团。
上述采用平板式出气罩， 并且平板式出气罩上均布有密集的斜孔出气孔， 具有更好 的效果， 具有压力的气体进入壳体内的腔体后， 由于斜孔的斜向角度， 刚进入腔体并且 未经反流腔反流缓冲的气体不容易直接从出气孔释放出来，这样更能保证出来的气体所 形成的气团无压力， 不会对肺部产生剌激作用。 上述形成的无压力的气团对人无直接的剌激作用， 更不会对肺部产生剌激并导致炎 症， 而且由于人的鼻子和嘴置于该装置的外面， 人呼出的气体能迅速的扩散， 不会造成 呼吸不畅或憋闷。
与现有技术相比， 本发明具有如下有益效果：
本发明的新型反流式供氧装置置于所需的位置， 如挂在适合人呼吸氧气的高度， 不 需要采用吊带或吊绳挂在脖子或头部， 人体活动更自由； 并且该新型反流式供氧装置采 用反流形式形成气团， 而非具有压力的风速， 从出气孔出来的气团无压力， 对人无直接 的剌激作用， 更不会对肺部产生剌激并导致炎症， 而且人呼出的气体能迅速的扩散， 不 会造成呼吸不畅或憋闷； 由于不采用直接罩在鼻子和嘴上的面罩， 因此呼出的气体和从 新型反流式供氧装置出气孔出来的气体很难混合在一起， 正像正常呼吸大气中的空气一 样自如顺畅。 附图说明

较佳的， 所述腔体的反流腔 6和回流腔 7之间的腔体部分呈圆柱形或椭圆形。 上述的壳体 2外形呈圆柱形 （如图 1， 图 2， 图 7所示）， 椭圆柱形或立体长方形等 各种尺寸均可， 只要其内部的腔体具有上述的所描述的形状， 并使得从出气孔出来的气 体形成气团即可。
本发明的新型反流式供氧装置， 如图 11 所示， 氧气或具有一定氧气含量的空气从 供氧管 1进入腔体 5内， 由于气体具有一定的压力， 该气体经远离供氧管的腔体一端的 反流腔 6的反流缓冲后， 气体受到反流腔 6的半心形形状的弧形壁 61缓冲作用， 之后 部分气体进一步经壳体内腔体 5的后侧壁 51的阻挡缓冲， 当然另一部分气体经反流腔 的半心形形状的弧形壁缓冲作用之后进入回流腔 7， 受到回流腔 7的半心形形状的弧形 壁 71缓冲作用 （当然有很少一部分气体经回流腔之后随进气在此进入上述的循环）， 这 两部分由具有一定压力的气体缓冲后， 经出气罩 4的出气孔 3释放出来， 形成无压力的 气团 8。
上述采用平板式出气罩， 并且平板式出气罩上均布有密集的斜孔出气孔， 具有更好 的效果， 具有压力的气体进入壳体内的腔体后， 由于斜孔的斜向角度， 刚进入腔体并且 未经反流腔反流缓冲的气体不容易直接从出气孔释放出来，这样更能保证出来的气体所 形成的气团无压力， 不会对肺部产生剌激作用。
上述形成的无压力的气团对人无直接的剌激作用， 更不会对肺部产生剌激并导致炎 症， 而且由于人的鼻子和嘴置于该装置的外面， 人呼出的气体能迅速的扩散， 不会造成 呼吸不畅或憋闷。
本发明的新型反流式供氧装置置于所需的位置， 如挂在适合人呼吸氧气的高度， 不 需要采用吊带或吊绳挂在脖子或头部， 人体活动更自由； 并且该新型反流式供氧装置采 用反流形式形成气团， 而非具有压力的风速， 从出气孔出来的气团无压力， 对人无直接 的剌激作用， 更不会对肺部产生剌激并导致炎症， 而且人呼出的气体能迅速的扩散， 不 会造成呼吸不畅或憋闷； 由于不采用直接罩在鼻子和嘴上的面罩， 因此呼出的气体和从 新型反流式供氧装置出气孔出来的气体很难混合在一起， 正像正常呼吸大气中的空气一 样自如顺畅。 上述实施例仅例示性说明本发明的原理及其功效， 而非用于限制本发明。 任何熟悉 此技术的人士皆可在不违背本发明的精神及范畴下， 对上述实施例进行修饰或改变。 因 此，举凡所属技术领域中具有通常知识者在未脱离本发明所揭示的精神与技术思想下所 完成的一切等效修饰或改变， 仍应由本发明的权利要求所涵盖。
