Description

急救口罩及其吹气结构 技术领域
本发明涉及一种口罩及其吹气结构，特别是一种急救用的口罩及其吹气结构。
现有技术
近年来，随着意外事件频发，如：心脏病、呼吸急症、溺水、触电、药物过量、异物哽塞或一氧化碳中毒等情况，却因为周遭人士无法对患者实时施行抢救，短短数分钟，就可能失去其宝贵的生命。只要发生上述情况，凡是患者有呼吸、心跳停止的情况时，都应立即实施心肺复苏术(Cardiopulmonary Resuscitation，CPR)予以急救。
通常人脑在缺氧四～十分钟之后，脑细胞就会开始受损，若超过十分钟就有无法复原的损伤，所以心肺复苏术(CPR)就是运用胸部按压与人工呼吸，以将血液持续供给心、肺及脑等人体的重要器官。
以人工呼吸进行时，施救人员可能因为不好意思，或患者呕吐，或担心患者本身会不会有传染病等其他问题，反而临阵畏惧或退缩，变得不敢施展，有的患者甚至是因吃下毒化物或喝强酸，陷入命危状况。若施救人员贸然实施口对口人工呼吸，仍有危害自身的隐忧。因此就产生一种人工呼吸面罩。
然而，现有的人工呼吸面罩，使用时有如下缺失：在对患者进行吹气的过程中，气流容易从患者口部周缘溢出，故无法使气流完全导入患者体内，严重影响施救质量；其次，无法确保施救人员及患者双方所吹入及呼出的空气皆完全有效过滤，故容易产生交互感染，提高染病风险并降低施救的意愿；若需移动患者身体或调整其头部时，面罩极易滑落而影响施救效率；再者，若患者颜面(包含眼部及额头处)有伤口，则无法对其血液、体液及黏膜等进行有效隔离，防护将产生很大的漏洞。
发明内容
本发明的目的之一在于提供一种急救口罩及其吹气结构，通过在插口管周围设置有封气罩的技术手段，以封闭从插口管与患者嘴部之间孔隙泄出的气体，以有效将气流完全导入至患者体内，大幅提升患者的存活机率。

本发明最佳实施方式
以下将藉由所列举的实施例并配合附图，详述本发明的结构与其特征功效。
请参阅图1至图3，它是本发明的一种急救口罩，其包含有一口罩体10、一吹气结构20以及一带体组30，分述如下：
口罩体10，设有外层11、中间层(图中未示)及内层13，外层11可为一防泼水透气布、纳米银织布、高耐酸碱能力的不织布或以上任意之组合，中间层可为一过滤棉或活性碳纤维，内层13可为一亲水层或一吸湿布。所述口罩体100更可为添加有香氛精油或中草药成分或其两者结合的口罩。
吹气结构20，包含有一通气座21、一套接件23以及一封气罩25：
其中，通气座21的中央系开设有一通孔211，而其外周缘则形成有一凸环215，所述通孔211可呈圆形、椭圆形或可与嘴形对合的形状。
其中，套接件23套设于通气座21的一端并与通气座21夹置所述口罩体10，套接件23具有一插口管233，气体可连通所述口罩体10、通气座21及插口管233。套接件23包含有一套筒231、与套筒231相连接的插口管233以及开设于套筒231内壁的一凹槽237(如图1所示)，凹槽237可对应通气座21的凸环215定位。
其中，插口管233对应外层11方向配置，插口管233用以将患者6口内的牙齿撑开和畅通输气；
其中，封气罩25连接套接件23并围绕插口管233配置，而封气罩25可为一橡胶环或一硅胶环。
带体组30，连接口罩体10。带体组30包括二挂带31，二挂带31分别固接于口罩体10的两侧，所述挂带31可为一弹性耳带、头挂式松紧带或者是一绑带。
请参阅图4所示，为本发明所提供的一种吹气结构20，它装设于一口罩体10，吹气结构20包含有：一通气座21、一套接件23以及一封气罩25，分述如下：
通气座21的中央系开设有一通孔211，而其外周缘则形成有一凸环215，所述通气座21的材料可为橡胶或者硅胶以提供舒适接触，通孔211可呈圆形、椭圆形或可与嘴形对合的形状。另可采用标准通气连接的通气座21，以与氧气供应系统连接。
套接件23是套设于通气座21的一端并与通气座21夹置所述口罩体10，套接件23具有一插口管233，气体可连通所述口罩体10、通气座21及插口管233。套接件23包含有一套筒231、与套筒231相连接的插口管233以及分别开设于套筒231之一端的一插槽235及内壁的一凹槽237，凹槽237可对应通气座21的凸环215定位，插口管233包含有至少一管孔234，且其用以将患者6口内的牙齿撑开和畅通输气，较佳地，插口管233的外径为8mm～16mm。
封气罩25连接套接件23并围绕插口管233配置，具体的连接方式有：封气罩25的一端系插设于套筒231的插槽235内，或封气罩25可与套接件23一体成型。其中，封气罩25的外径为40mm～60mm，厚度为1mm～5mm，其可为一橡胶环或是一硅胶环，且可选用医疗等级的硅胶，另具有适当的强度，以提供良好支撑和舒适接触。
使用本发明时，可如图5所示，急救人员或施救者5佩戴本发明后，令插口管233伸入患者6的口腔内，并让封气罩25完整罩覆患者6口部，再捏住患者6鼻部后，即可对患者6吹吐气流，实施口对口人工呼吸，以畅通施救。
其中，于吹吐气流时，因口罩体10具有较佳的透气性，吹入适当压力的气流，即可将气流完全顺利地导入至患者6体内，故不会发生吹入至患者6体内的空气量有不足的情况。
上述，因在插口管233周围设置有封气罩25，用以封闭从插口管233与患者6口部之间孔隙所泄出的气体，故能有效将气流完全导入至患者6体内，大幅提高其存活机率。
同时，口罩体10能同时达到过滤施救者5所吹进及患者6所呼出的病毒及细菌，防止交互感染，故能提高施救者5的施救意愿及质量。
其中，口罩体10的外层11是采用防泼水透气布、纳米银织布或其两者的组合的设计，除了用以减少长时间施救时产生的闷热感，让佩戴更舒适透气外，更能够有效杀死病毒及细菌。
本发明另一可使用方式，如图6所示，可将本发明佩戴于患者6，使插口管233伸入患者6口腔内，让封气罩25完整罩覆患者6口部，且适当调整鼻梁 片并压合，施救者5以手捏住患者6的鼻部后，以口对接通气座21的通孔211，对患者6吹吐气流，实施口对口人工呼吸以畅通施救，如此，同样能达到前述效果。
其中，通过带体组30及插口管233固定在患者6上的方式，可避免施救过程中造成口罩体10偏移或滑落，影响急救进行，故藉以能提高施救效率。
前述更可包括一对反折片15，分别从口罩体10的侧边延伸出，且反折后以反折片15的两末端固接于口罩体10。通过反折片15的设计，能让患者6佩戴后完全密合脸形，于施救中能防止气流从口罩体10与脸部间的孔隙窜出，以减低周遭人员受感染的风险。同时以阻挡外部的污染物进入，以提高施救质量。
前述更可包括一护目罩40，固接于外层11并延伸出口罩体10外，护目罩40具有防水、耐酸碱及腐蚀的能力。通过口罩体10及固接有护目罩40的技术，以有效阻隔施救者5或/及患者6(包括眼部及额头处)的血液、体液、黏膜及伤口等，防止交叉感染接触，以达到全面性防护，使救护更安全卫生。
另外，除了患者6佩戴有本发明外，施救者5更可佩戴有一口罩(图中未示)，以对患者6进行吹气施救，此乃藉由更多层的保护，以进一步提升防护效果。
请一并参阅图7及图8，它是本发明所提供的另一较佳实施例，主要是概同于前揭实施例，而其不同之处在于：
其更可包括有一导气罩27，连接通气座21的另一端。导气罩27可为一橡胶环、硅胶环或是一套管，硅胶环较佳地可选用择医疗等级的硅胶，而套管可供一氧气供应设备连接。
通气座21具有一通孔211及绕设于通孔211外的一沟槽213，而导气罩27的一端则插接于沟槽213内或导气罩27可与通气座21一体成型。
上述是通过在通气座21上连接有导气罩27的技术，使施救者5口对接后吹出的气流完全由导气罩27集中导入，避免气流可能从嘴部与通气座21之间的隙缝泄出，以充分有效利用导入的输气量。
请参阅图9所示，它是本发明所提供的另一较佳实施例，主要是概同于前揭实施例，而其不同之处在于：
套接件23的套筒231与插口管233连接的端面开设有若干导气沟238，这些导气沟238气连通插口管233，以在进行输气时，气流能经由这些导气沟238集中引入插口管233，进而导入至患者6体内，同样能达到前述效果。
请参阅图10所示，它是本发明所提供的又一较佳实施例，主要是概同于前揭实施例，而其不同之处在于：
套接件23的套筒231与插口管233连接的端面开设有贯穿的若干孔洞239，封气罩25则对接后并包围这些孔洞239，除了通过插口管233进行输气外，气流更能穿经这些孔洞239从插口管233与患者6口部之间的孔隙导入患者6体内，同样具有前述效果。
请参阅图11所示，它是本发明提供的再一较佳实施例，主要是概同于前揭实施例，而其不同之处在于：
本发明的吹气结构20可应用或装设于一N95型口罩7，所述的N95型口罩7，为使用二条具高拉力的头挂式的松紧带71，以增加口罩7与脸部的紧贴与密合。
惟需注意的是，本发明能有效隔离双方口部的直接接触，于施救中可避免让患者6感到无意间被侵犯，待患者6清醒后可减低双方尴尬的窘境。
综合前述，本发明相较于先前技术具有以下功效：佩戴舒适透气，更能充分有效将施救者的输气量完全导入至患者体内，以大幅提升患者的存活机率，同时防止双方交互感染，以提高施救的意愿及质量，且提高了施救的效率，更能达到全面防护的效果。
最后，必须再次说明，凡于本发明领域中具有公知常识者应能明确知悉，该等详细说明以及本发明所列举的实施例，仅适于说明本发明的结构其欲达成的功效，而非用以限制本发明的权利要求的范畴，其他等效元素、组件、对象、结构或装置的替代或变化，亦应为本发明权利要求所涵盖。
工业应用性
本发明提供的急救口罩及其吹气结构，在临床应用上具有广泛的应用前景，因此具有广阔的工业应用性。
