Description

一种雾化器储雾罐 技术领域
本发明属于医疗器械技术领域，涉及雾化器储雾罐的创新与改进，具体说是一种雾化器储雾罐。
 背景技术
使用雾化器雾化治疗，是将药物变成细小的颗粒，让药物随着人体的呼吸，直接进入呼吸道和肺部，以达到缓解因呼吸道和肺部原因引起的哮喘、咳嗽之类的呼吸道病症的一种治疗方法。目前也有相关企业和研究部门在研究除呼吸道疾病以外的其它病症的治疗，被认为除口服、注射以外的第三种给药方式即呼吸道给药，例如：胰岛素通过呼吸道给药，心脏急救呼吸道给药。如何提高给药效率以及药物递送剂量是所有雾化设备制造商和医生共同关注的问题，因此，利用储雾罐减少药物弥散是目前最直接、最简易、成本最低的方法。
目前，常见雾化器储雾罐大都应用于气雾剂给药场景，用于改善患者按压气雾剂与吸入动作胁从性不好的情况下使用。另一方面，雾化器储雾罐的作用，可以使雾化器喷出的药物贮于储雾罐，药物颗粒与储雾罐内的空气充分混合，病人从储雾罐吸入药物，可增加雾化的疗效，并减少因药物吸入导致的呛咳感和憋闷感以及其它的副作用。但是，现有的储雾罐存在以下问题：1.常见储雾罐大都配合气雾剂使用，压缩雾化器以及微网雾化器基本没有储雾罐配合；2.传统储雾罐药物弥散率高，递送量低；3.药物与储雾罐内的空气混合不充分，部分沉积在储雾罐内壁上，造成浪费；4.使用者吸入治疗时因为储雾罐体与外界封闭而产生负压，导致患者吸入费力，且吸入的氧气量少而产生憋气的现象；5.现有储物罐仅有储雾功能，无氧气管接口，无法在实现使用储雾罐的情况下边吸氧边进行雾化。
 技术问题
如何设计一种雾化器储雾罐，提高雾化递送量，降低损耗，解决雾化与吸入胁从性问题，扩展雾化应用人群，提高雾化质控能力。这是本领域亟待解决的技术问题。
 技术解决方案
本发明为解决现有技术存在的上述问题，提供一种雾化器储雾罐，可减少药物雾粒附着于储雾罐内壁的机率，提高药物利用率，细化药物颗粒、降低药物弥散量、提高递送剂量；进一步地，还具有实现边吸氧边雾化、减少患者产生憋气现象的功能。
本发明的目的是通过以下技术方案实现的：
一种雾化器储雾罐，包括罐体，所述罐体前端上设置出雾口，其特征在于，所述的罐体后端上设置进口，所述进口上设置有可拆卸方式安装的后盖，所述的后盖上设置进雾口、进气口及进气单向阀。
对上述技术方案的改进：所述进气单向阀为螺旋进气单向阀，所述螺旋进气单向阀的本体为圆环形，所述螺旋进气单向阀的中心开孔直径不小于所述进雾口内壁直径，所述螺旋进气单向阀环绕设置在所述进雾口周围，且所述螺旋进气单向阀的厚度自内沿至外沿逐渐变薄，沿所述螺旋进气单向阀径向至少开设3条瓣间开口并至少形成3个瓣片，且在每个所述瓣片上设有固定口，所述进气单向阀采用柔性材料制成。
对上述技术方案的进一步改进：所述的后盖为圆桶形，所述进雾口为管状进雾口，所述管状进雾口设置在所述后盖的圆桶底部中心位置，且向外伸出；在后盖上围绕所述管状进雾口周围设有至少3个所述进气口和至少3个螺旋进气单向阀固定槽。
对上述技术方案的进一步改进：所述螺旋进气单向阀配置一固定卡环，所述固定卡环为圆环形，所述固定卡环上设有固定卡扣，所述固定卡扣分别与所述螺旋进气单向阀上的固定口以及所述后盖上的螺旋进气单向阀固定槽一一对应；所述固定卡环通过定位卡扣穿过所述螺旋进气单向阀上的固定口，与所述后盖上的螺旋进气单向阀固定槽密切衔接扣合，将所述螺旋进气单向阀固定于所述后盖上。
对上述技术方案的进一步改进：所述固定卡环周边沿径向延伸出固定爪，所述固定爪数量与螺旋进气单向阀上瓣片的数量一致，所述固定爪用于固定螺旋进气单向阀上的瓣片部分边沿，使所述螺旋进气单向阀打开时呈螺旋叶扇状，使流经所述螺旋进气单向阀的空气被所述螺旋进气单向阀导流呈螺旋状贴着罐体内壁进入罐体。
对上述技术方案的进一步改进：所述罐体上设置卡扣，在所述后盖的圆桶形侧壁上对应设置储雾罐固定卡槽，所述罐体与后盖之间采用过盈配合插接密封，由所述卡扣与储雾罐固定卡槽卡合连接固定；所述罐体上设置的出雾口沿所述进雾口进雾方向设置。
对上述技术方案的进一步改进：在所述后盖的圆桶形底部还设置有氧气管接口。
对上述技术方案的进一步改进：所述罐体上的出雾口配有带有呼气单向阀的雾化口含器或带有呼气单向阀的雾化面罩。
 有益效果
本发明的优点和积极效果是：
1、本发明的雾化器储雾罐设置有可与罐体分离的后盖，在后盖上设置进雾口、进气口和螺旋进气单向阀，进气口环绕在进雾口四周，进气方向与进雾口方向一致，螺旋进气单向阀中心开孔与进气口重叠并环绕在进雾口周围。螺旋进气单向阀通过单向阀固定卡环固定在后盖内，螺旋进气单向阀分割成多片瓣片，单向阀固定卡环有数量与瓣片数相同的固定爪，可以固定住每一个螺旋进气单向阀上每一瓣片的部分边沿。当患者吸气时，罐内形成负压，大气压将气流压入储雾罐，气流将未被单向阀固定卡固定的瓣片边沿推开，此时单向阀呈螺旋状，进入罐体的空气被螺旋形状的单向阀导流，形成沿储雾罐内壁以储雾罐中心为轴的螺旋气流，这样，能够有效的将内壁上的雾粒带走，可以减少药物附着在罐壁上的机率，大颗粒因飞行距离较近很快可以形成液体，细小的雾化颗粒，则随着患者的吸气气流流入呼吸道，提高药物递送量率、减少副作用。
2、本发明的雾化器储雾罐在后盖上设置有进气孔，且螺旋进气单向阀采用软性材质，容易打开和复位，可以减少患者因缺氧而产生憋气现象。
3、本发明的雾化器储雾罐罐体上设有出雾口，出雾口配合带有呼气单向阀的雾化口含器或带有呼气单向阀的雾化面罩使用，当患者向储雾罐呼气时，位于储雾罐出雾口处的雾化口含器或雾化面罩上的呼气单向阀打开，储雾罐上的吸气单向阀关闭，罐内气雾得以暂存，患者呼吸道内呼出的气体随呼气单向阀的打开而流出，不影响罐内药物，待患者下一个吸气周期随吸气吸入呼吸道，达到减少弥散提高递送量的目的。
4、本发明的雾化器储雾罐在后盖上设置的氧气管接口可配合制氧机、呼吸机等医疗设备使用。
5、本发明的雾化器储雾罐采用全部易拆卸设计，便于雾化罐的清洗、消毒和重复使用，避免交叉感染。

在罐体2上设置卡扣2.1，在后盖5的圆桶形侧壁上对应设置储雾罐固定卡槽5.1，通过罐体2与后盖5通过卡扣2.1和储雾罐固定卡槽5.1连接，罐体2与后盖5之间采用过盈配合插接密封，由卡扣2.1与储雾罐固定卡槽5.1卡合连接固定。
优选地，上述进气单向阀4采用TPE、硅胶、TPU、橡胶等采用柔韧弹性材质制作，进气单向阀4容易打开和复位，可以减少患者因缺氧而产生憋气现象。
使用时，先将螺旋进气单向阀4安装在螺旋进气单向阀固定卡环3上，再安装至后盖5上，然后，将后盖5上的储雾罐固定卡槽5.1对准罐体2上的卡扣2.1卡接，并安装上带有呼气单向阀1.1的雾化口含器1组装成雾化器储雾罐，如图4所示。再将雾化器储雾罐的进雾口5.4与雾化器的出雾口对接，如图5所示，启动雾化器进行雾化。当患者吸气时，雾化口含器1上的呼气单向阀1.1关闭，雾化器储雾罐内会形成负压，外部大气压将空气压入雾化器储雾罐。螺旋进气单向阀4被气流打开，在螺旋进气单向阀固定卡环3伸出的固定爪3.2附近的瓣片4.1会掀开一个较小的距离，远离固定爪3.2的位置会掀开一个较大的距离。这样，进气瓣片4.1与后盖5的底面就会形成一个锐角夹角，通过气流对3个（或多个）瓣片4.1的同时作用，瓣片4.1呈螺旋叶扇状。进入雾化器储雾罐的气流在已经呈螺旋叶扇状的螺旋进气单向阀4的作用下，形成沿罐体2内壁螺旋且以罐体2轴向为轴的螺旋气流，减少药物在罐体2内壁上的附着的机率，从而达到减少药物附着在罐体2内壁形成残留液体的目的，从而提高吸气时药物利用率，提高递送计量。当患者呼气时，患者呼出的气体随雾化口含器1上的呼气单向阀1.1流出，罐体2内气压大于外界大气压，螺旋进气单向阀4关闭，罐体2内的药物得以保留，减少或避免药物耗散，从而达到降低药物弥散量、提高药物利用率和高递送量的目的。
需要清洗时，将卡扣2.1与储雾罐固定卡槽5.1脱开，使后盖5和罐体2分离，拆下螺旋进气单向阀固定卡环3，将螺旋进气单向阀4与螺旋进气单向阀固定卡环3分离，可对雾化器储雾罐进行全面清洗。
当然，上述说明并非是对本发明的限制，本发明也并不限于上述举例，本技术领域的普通技术人员，在本发明的实质范围内所做出的变化、改型、添加或替换，也属于本发明的保护范围。
