技术领域
本申请涉及医疗器械领域，尤其涉及一种吸氧鼻塞装置。
背景技术
在临床医学中，输氧工作是最基本的护理工作之一，尤其对于呼吸治疗患者，经常需要输氧，此过程需要用到吸氧鼻塞，吸氧鼻塞是在医疗中用来供患者吸氧气的装置，其一端连接供氧源，另一端的鼻塞插入患者的鼻部，随着科学技术的发展，吸氧鼻塞也越来越多，而且功能也越来越强大。
目前，吸氧鼻塞的结构简单，佩戴方便，使用广泛，但是在长期佩戴情况下，鼻塞的出气孔伸入到病人鼻腔内，会出现鼻腔变形等副作用，而且由于鼻子内部的构造以及需要用鼻子出气，在鼻塞位置容易形成冷凝水并存积引起冷凝水容易呛入患者鼻腔，使患者感到不适，有时候还会导致鼻部细菌的感染，造成健康隐患。此外，现有的吸氧鼻塞也非常容易掉落，导致塞体从患者鼻腔内脱落，影响鼻子舒适度。
因此，急需发展一种吸氧鼻塞装置，既能够避免冷凝水容易存积在鼻塞位置，舒适的为患者输氧，保障患者的生命健康，也能够避免吸氧鼻塞装置容易掉落、移位的问题。
发明内容
本申请提供一种吸氧鼻塞装置，用以至少解决冷凝水容易积存在鼻塞位置，影响输氧舒适度，以及吸氧鼻塞装置容易掉落、移位的技术问题。

本申请提供的吸氧鼻塞装置，通过挂绳组件将鼻塞组件固定在患者的鼻孔处，防止鼻塞组件容易从患者的鼻孔处脱落，影响使用效果，此外，还设置了颈绳组件，使得在导管组件远离鼻塞组件的一段被固定在患者的颈部，减少了因整体重力使得导管组件容易活动，而导致鼻塞组件部分下沉或翻转脱落的问题发生，本申请能够有效减少吸氧鼻塞装置容易掉落、移位的现象发生，保障患者的生命健康。
在一种可能实施的方式中，所述鼻塞组件包括鼻塞本体和连接在所述鼻塞本体侧面的一对鼻孔凸柱，所述鼻塞本体内具有呈收缩状的气流腔，所述一对鼻孔凸柱内分别具有与所述气流腔相贯通的出气孔。

具体实施方式
为使本申请的目的、技术方案和优点更加清楚，下面将结合本申请中的附图，对本申请中的技术方案进行清楚、完整地描述，显然，所描述的实施例是本申请一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
临床上通过给患者供氧能够纠正各种原因造成的缺氧状态，促进患者身体组织的新陈代谢，维持生命活动，目前常用的呼吸治疗患者接口有气管插管、口面罩及鼻氧管几种，其中吸氧鼻塞装置作为一种鼻氧管，其结构简单，佩戴方便，被广泛使用。
使用时，吸氧鼻塞装置通过机器端和供氧装置连接，经过导气管的输送，到患者的鼻腔位置为患者输入氧气，缓解各种因缺氧而造成的临床症状，但是现有的吸氧鼻塞装置存在着容易脱落、移位的问题，其部分原因是由于吸氧鼻塞装置自重导致的脱落、移位，特别是在患者翻身误撞等动作时，非常容易造成吸氧鼻塞装置脱落、移位。此外，现有的吸氧鼻塞装置还存在着冷凝水容易堆积在鼻塞内部，导致患者呼吸时吸入冷凝水被呛到的问题，甚至引起患者鼻部细菌感染，影响患者的生命健康。
为了解决现有的吸氧鼻塞装置鼻塞容易脱落、移位的问题，以及患者呼吸时容易吸入冷凝水被呛到的问题，本申请对吸氧鼻塞装置的结构进行了改进，提供了一种吸氧鼻塞装置。
下面参考附图1-7描述本申请实施例提供的吸氧鼻塞装置。
鉴于上述背景，参考图1所示，本申请提供一种吸氧鼻塞装置，包括：导管组件10、鼻塞组件20、挂绳组件30和颈绳组件40，导管组件10为中通的管状结构。
具体的，中通指的是导管组件10内具有贯穿导管组件10两端的通道，该通道为输送氧气提供流通的通道。
参考图1所示，鼻塞组件20设置在导管组件10的一端，导管组件的另一端用于与供氧装置连通，且鼻塞组件20与导管组件10贯通连接，供氧装置提供的氧气通过导管组件10向鼻塞组件20输送。
挂绳组件30设置在鼻塞组件20上，挂绳组件30用于套设在患者的头部， 以使鼻塞组件20固定在患者的鼻孔处，提高固定的稳定性，避免由于患者翻身、误撞等动作导致鼻塞组件20脱落或者移位，为患者提供了生命安全保障。
颈绳组件40用于将导管组件10的另一端固定在患者的颈部，颈绳组件40用于固定导管组件10远离鼻塞组件20的一段，避免由于重力作用引起导管组件10下落，增加了使用的稳定性。
本申请提供的吸氧鼻塞装置，用于供吸氧时氧源与患者之间的氧气直接输送或湿化后输送，结构简单合理，使用方便，佩戴舒适，不容易脱落。
参考图4和图5所示，鼻塞组件20包括鼻塞本体21和连接在鼻塞本体21侧面的一对鼻孔凸柱22，即鼻孔凸柱22的数量为两个，当然，在一些示例中，鼻孔凸柱22的数量包括但不限于为一对，也可以为两个以上，这样其余鼻孔凸柱22可以作为备用的，当其中一个鼻孔凸柱22出现故障时，可以使用备用的鼻孔凸柱22。
具体的，鼻塞本体21与一对鼻孔凸柱22为一体式成型的整体结构，确保了良好的气密性。
参考图5所示，鼻塞本体21内具有呈收缩状的气流腔211，收缩状的气流腔211指的是沿着气流的流通方向，气流腔211的口径逐渐缩小，具体指气流腔211的口径在靠近鼻孔凸柱22的方向逐渐缩小。一对鼻孔凸柱22内分别具有与气流腔211相贯通的出气孔221，使用时，一对鼻孔凸柱22分别接入患者的鼻腔内部，进入到气流腔211内的氧气由出气孔221输出，出气孔221的结构符合大众的鼻腔结构，降低了长期佩戴对鼻腔造成损伤的可能性。
参考图5和图7所示，气流腔211的一侧内壁具有倾斜面213，气流腔211的另一侧内壁具有弧形面212。具体的，弧形面212为圆滑过渡的圆弧形曲面。
气流腔211之所以呈现出收缩状，是由于弧形面212在靠近气流腔211的进气口端时，向远离倾斜面213的方向扩张；并且，弧形面212在远离气流腔211的进气口端时逐渐向倾斜面213靠近，直至与倾斜面213相交。
在一种可能实施的方式中，倾斜面213的倾角θ为5°～15°，例如，倾斜面213的倾角θ可以为8°，倾斜面213的倾角θ还可以为10°。
优选的，倾斜面213的倾角θ为5°。
参考图7所示，为了使得气流腔211内产生的冷凝水更加顺利的流出，弧形面212的切线方向与竖直方向的角度范围为0°～19°。
这里需要说明的是，本申请涉及的数值和数值范围为近似值，受制造工艺的影响，可能会存在一定范围的误差，这部分误差本领域技术人员可以认为忽略不计。
本实施例中，通过设置弧形面212能够方便气流腔211内的冷凝水流走，避免冷凝水在气流腔211内堆积，从而减少了在鼻塞本体21内存积冷凝水，减小患者呼吸时被冷凝水呛到的隐患。
呈收缩状的气流腔211结构符合气体流动规律，气流阻力小，不易于冷凝水的形成，并且气流腔211一侧内壁的倾斜面213具有一定的倾斜角度，使得患者在使用该吸氧鼻塞装置时，鼻塞本体21的整体与患者鼻孔端的平面呈现出倾斜角度，可以使冷凝水顺利回流到导管组件10内，避免冷凝水存积呛入患者鼻腔，其中，参考图7中虚线所示为患者鼻孔端的平面。
参考图4和图5所示，挂绳组件30包括分别设置在鼻塞本体21两侧的第一挂绳连接件31和第二挂绳连接件34，例如，参见图5所示，第一挂绳连接件31位于鼻塞本体21的上侧，第二挂绳连接件34位于鼻塞本体21的下侧。
在一种可能的实现方式中，第一挂绳连接件31和第二挂绳连接件34与鼻塞本体一体式成型，一体式成型的结构使得在佩戴吸氧鼻塞装置时，鼻塞本体放置到患者的人中位置后，第一挂绳连接件和第二挂绳连接件与人脸弧度很好的吻合，更加贴合人脸，对患者面部的压迫感较小，减少了对皮肤敏感的患者造成皮肤损伤的隐患，佩戴舒适。挂绳组件30能较好地固定鼻塞组件20，也不会对患者的皮肤造成压迫损伤。
当然，在另一实施例，第一挂绳连接件31和第二挂绳连接件34与鼻塞本体也可以通过卡接、粘接或者紧固件进行相连。
挂绳组件30还包括连接在第一挂绳连接件31和第二挂绳连接件34之间的挂绳32。
具体的，第一挂绳连接件31与挂绳32的一端通过连接扣33连接，第二挂绳连接件34与挂绳32的另一端通过连接扣33连接。
具体的，挂绳32采用柔软且有弹性的材质，如橡胶等材质，第一挂绳连 接件31和第二挂绳连接件34采用质地柔软，透气性好，对皮肤刺激性小的材质，如硅橡胶，来提高使用舒适度。
挂绳32上设置有调节扣35，挂绳32反复穿过调节扣35，实现挂绳32长度调节的功能，适合不同头围大小的患者。
导管组件10包括导气管11、上接头13和下接头14，上接头13和下接头14分别连接在导气管11的两端，鼻塞本体21与上接头13贯通连接。
具体的，导气管11的内部具有气流通道111，进入到气流通道111内的氧气输送到气流腔211内，再由出气孔221输出。
导气管11上设置有挂绳夹12，挂绳夹12用于将挂绳32固定于导气管11上，在患者佩戴该吸氧鼻塞装置时，减少由于重力作用导致鼻塞组件20下沉或翻转的可能。
导气管11可以采用塑料软管制成，可伸缩。也可变直或者变弯，随患者的需要改变调整。
优选的，导气管11可以为螺纹管。
作为本实施例的另一实施例，参考图2所示，吸氧鼻塞装置还包括接头组件50，接头组件50贯通连接在导管组件10的另一端，接头组件50包括机器接头51和连接在机器接头51一端的接头连接件52。
参考图6所示，接头连接件52与下接头14连接，机器接头51用于与供氧装置连接或者与呼吸机特定的加热呼吸管路连接。
在下接头14的外周上设置有凹槽141，接头连接件52内部具有卡爪521，卡爪521与凹槽141相适配，卡爪521卡在凹槽141内，实现接头连接件52与下接头14的扣合连接，扣合式连接的机构，安装方便，且使得接头组件50可相对于下接头14自由旋转，保证患者在佩戴该吸氧鼻塞装置的过程中，导气管11不会出现弯折扭转的现象。
参考图3和图4所示，颈绳组件40包括颈绳41、弹簧扣42和颈绳扣43，颈绳41的两端通过颈绳扣43相互连接，弹簧扣42设置在颈绳41上，颈绳扣43扣合时，颈绳41成为环状整体，颈绳扣43打开时，颈绳41的两端分开。颈绳41用于佩戴在患者的颈部，起到固定导气管11的作用。述颈绳扣43的开合操作方便，打开颈绳扣43可以方便地将颈绳41系于患者颈部后再扣合，避免干扰到患者的头部、颈部等其他部位，也便于医护人员拆卸。
弹簧扣42穿过颈绳41，弹簧扣42用于调节颈绳41的长度，可根据不同患者的使用需求来调节颈绳41的长度。
使用时，将机器接头51连接在供氧装置上，设置供氧设备的参数：比如:温度调整到37℃，流量40L/min，鼻孔凸柱22的出气孔221有湿化气体流出,将鼻塞本体21正确佩戴到患者面部，鼻孔凸柱22插入到患者的鼻孔内，第一挂绳连接件31和第二挂绳连接件34贴合在患者的面部，将第一挂绳连接件31与挂绳32的一端通过连接扣33扣合，再将第二挂绳连接件34与挂绳32的一端通过连接扣33扣合，通过调节扣35来调节挂绳32的长度，使得挂绳组件30的正好与患者的头部大小适应，以确保佩戴牢固、舒适；将颈绳41系在患者的颈部，调整颈绳41的长度以确保佩戴牢固、舒适，从而使得该吸氧鼻塞装置被牢固的固定，避免导管组件10活动引起鼻塞组件20脱落。
