Description

储雾罐和吸入装置 技术领域
本发明涉及医疗设备技术领域，具体涉及一种储雾罐和吸入装置。
背景技术
储雾罐，也叫筒式吸舒，英文名称叫"Spacer"或者“chamber”，是配合定量气雾剂装置(MDI)完成吸入疗法的辅助工具。MDI喷出的药雾贮于储雾罐，病人从储雾罐吸入药雾，以增加MDI的疗效，并减少药雾的副作用。储雾罐主要用于小儿以及吸气和手部动作配合不好的病人，或者使用MDI后咽喉部副作用明显的病人。特别是对于糖皮质激素，用储雾罐会明显减少吸入糖皮质激素的局部副作用以及潜在的全身副作用。
MDI喷出的药雾可暂时储存于储雾罐中，药雾颗粒和储雾罐内的空气混合，以此解决了MDI喷药与患者吸气不同步问题，而且患者可通过储雾罐做多次吸气。同时，相比于直接使用MDI来吸入药雾，采用储雾罐吸入气道和肺组织的药雾量较多，停留在口咽部的药量明显减少，因此疗效明显增加，对口咽部的刺激作用则大大减少。
传统的储雾罐为了保证疗效，体积一般较大，不易携带。此外，由于传统储雾罐一般采用不锈钢、PVC(聚氯乙烯)或高分子等材质制成，因此造价比较高，为患者带来较高的经济负担(患者每三个月需要更换一次)。同时，传统的储雾罐还需要经常拆开清洗，清洗后还只能在阴凉地方晾干，整个清洗过程费时费力，容易滋生细菌造成二次感染。
发明内容
有鉴于此，本发明实施例提供了一种储雾罐和吸入装置，解决了传统储 雾罐的体积较大、不易携带的问题。

具体实施方式
下面将结合本发明实施例中的附图，对本发明实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅是本发明一部分实施例，而不是全部的实施例。基于本发明中的实施例，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，都属于本发明保护的范围。
图1所示为本发明一实施例提供的一种储雾罐的结构示意图。如图1所示，该储雾罐包括：罐体1、以及设置于罐体1上的呼吸口2和进雾口3。该罐体1构造为可折叠结构。进雾口3用于与外部的气雾剂装置的出雾口对接，用于将气雾剂装置输出的气雾导入罐体1。气雾在进入罐体1后可与罐体1内的空气充分混合。呼吸口2用于与使用者的嘴对接，以便于使用者通过该呼吸口2吸入罐体1中的气雾。
应当理解，虽然图1中的呼吸口2由两个孔组成，但呼吸口2具体所包括的孔的个数可根据实际需求而调整，本发明对此不做限定。
由于罐体1构造为可折叠结构，因此储雾罐可被折叠成一定形状以缩小占用空间，达到便于携带、便于收纳以及便于运输的目的。
在本发明一实施例中，罐体1可采用纸质材料制成，这样罐体1可被折叠，以起到缩小占用空间的作用。同时，由于纸质材料的造价较低，不仅可为生产厂家降低生产成本，也为使用者降低了经济负担。此外，纸质材料制成的储雾罐可以作为一次性产品使用，从而节省了现有技术中的清洗步骤，也避免了清洗步骤所带来的细菌感染问题。
应当理解，罐体1也可采用除纸质材料外的其他可折叠材料制成，本发明对罐体1的材质不做严格限定。
图2所示为本发明另一实施例提供的一种储雾罐的结构示意图。如图2所示，该储雾罐的罐体1的表面包括预设的折叠线13，以使得罐体1在外力下沿这些折叠线13被折叠成预设形状。当然，在相反的外力作用下也可沿这些折叠线13展开成折叠之前的立体形状。在本发明一实施例中，如图2所示，罐体1沿折叠线13折叠成的预设形状可为扁片状，这样折叠后的储雾罐可堆叠放置，以便于使用者携带。
应当理解，储雾罐的罐体1表面的折叠线13可根据实际的场景需求而设计，折叠后的预设形状也可根据实际的场景需求而设计调整，本发明对罐体1表面的折叠线13以及折叠后的预设形状不做限定。
在本发明一实施例中，为了使得来自气雾剂装置的气雾能与罐体1内的空气充分混合，呼吸口2和进雾口3之间可设计为有较大的间距。例如图1或图2所示，呼吸口2可设置在罐体1在一维方向上的第一端11，进雾口3设置在罐体1在一维方向上与第一端11相对的第二端12。但应当理解，这里所说的一维方向可以是在三维空间内的任一个一维方向。例如当罐体1为长方体形状时，该一维方向可以是长度方向，可以是宽度方向，还可以是高 度方向。本发明对该一维方向的在三维空间中的具体方向不做限定。
在一进一步实施例中，当呼吸口2设置在罐体1在一维方向上的第一端11，进雾口3设置在罐体1在一维方向上与第一端11相对的第二端12时，第一端11的截面积可设计为小于第二端12的截面积。例如图1或图2所示，第一端11的宽度就明显小于第二端12。通过减小包括呼吸口2的第一端11的截面积，可使得罐体1内的气流在使用者吸气时更加集中和快速的被吸入使用者口腔，罐体1向口腔输出的出雾量更大，使得使用者在吸气的时候能更省力，储物罐的气雾残留更少，更利于气雾在使用者肺部的沉积。
在本发明一实施例中，如图1或图2所示，该第一端11上的呼吸口2可设计为扁平状的含嘴。该含嘴上可包括一个或多个孔。将呼吸口2设计成扁平状的含嘴形状，使得使用者可以更方便的用嘴含住该呼吸口2，以提高呼吸过程中的气密性。
图3所示为本发明另一实施例提供的一种储雾罐的结构示意图。如图3所示，该储雾罐的罐体1包括：第一腔室14、第二腔室15以及设置在第一腔室14和第二腔室15之间的第一单向阀4，该第一单向阀4用于将第二腔室15中的气流单向导入第一腔室14。呼吸口2设置在该第一腔室14的表面、进雾口3设置在该第二腔室15的表面。
这样当使用者通过呼吸口2吸气时，罐体1内便会产生从第二腔室15先第一腔室14中的气流。此时，该第一单向阀4便会打开，以将第二腔室15中的气雾随着气流导入第一腔室14，并通过呼吸口2使得气雾被使用者吸入口腔。当使用者并未使用呼吸口2吸气时，外部的气雾剂装置通过进雾口3输送到罐体1中的气雾则会停留在该第二腔室15中，以与第二腔室15中的空气充分混合。而当使用者通过呼吸口2呼气时，由于气流的方向与该第一单向阀4的打开方向相反，因而该第一单向阀4会保持关闭状态，以避免使用者呼出的气雾返回第二腔室15。
应当理解，虽然图3中示出了两个第一单向阀4，但第一单向阀4的个 数可根据实际的需求而调整，本发明对第一单向阀4的个数不做限定。
图4所示为本发明另一实施例提供的一种储雾罐的结构示意图。与图3所示的储雾罐相比，图4所示的储雾罐进一步包括了设置在第一腔室14表面的第二单向阀5，用于将第一腔室14中的气流单向导出储雾罐。这样当使用者通过呼吸口2呼气时，该第二单向阀5便会打开，以将使用者呼出的气雾随着气流导出储雾罐，而第一单向阀4会保持关闭状态。当使用者通过呼吸口2吸气时，该第二单向阀5便会关闭，以避免第一腔室14中的气雾泄露到储雾罐外部。
应当理解，虽然图4中示出了两个第二单向阀5，但第二单向阀5的个数也可根据实际的需求而调整，本发明对第二单向阀5的个数不做限定。
在一进一步实施例中，如图4所示，该第二单向阀5可设置在第一腔室14在竖直方向上的底面。这样当用户使用该储雾罐时，呼出的气雾便会通过该第二单向阀5从储雾罐的下方排出，以避免气雾从其他方位排出而刺激到使用者的眼睛和鼻腔。
图5所示为本发明另一实施例提供的一种储雾罐的结构示意图。与图3所示的储雾罐相比，图5所示的储雾罐进一步包括了：设置于第二腔室15表面的密封观察窗6，该密封观察窗6采用透明材料制成。这样使用者可通过该密封观察窗6的观察到第二腔室15内的气雾是否被使用者吸尽，如果已经吸尽则说明已经完成本次的给药过程。在本发明一实施例中，该密封观察窗6可采用PET(耐高温聚酯)薄膜材料制成。当罐体1采用纸质材料制成时，可先在第二腔室15表面开孔，再采用环保胶水将该PET薄膜材料与该开孔密封粘合。然而应当理解，该密封观察窗6也可采用其他透明材料制成，本发明对此不做限定。
在一进一步实施例中，如图5所示，密封观察窗6可设置在第二腔室15在竖直方向的上表面，以便于使用者在使用该储雾罐时，通过眼睛向下查看该密封观察窗6。
本发明一实施例还提供的一种吸入装置。该吸入装置包括：气雾剂装置以及如前任一实施例所述的储雾罐。储雾罐的进雾口3与气雾剂装置的出雾口对接，用于将气雾剂装置输出的气雾导入罐体1。气雾在进入罐体1后可与罐体1内的空气充分混合。储雾罐的呼吸口2用于与使用者的嘴对接，以便于使用者通过该呼吸口2吸入罐体1中的气雾。
由于储雾罐的罐体1构造为可折叠结构，因此储雾罐可被折叠成一定形状以缩小占用空间，达到便于携带、便于收纳以及便于运输的目的。
应当理解，本发明实施例描述中所用到的限定词“第一”、“第二”等仅用于更清楚的阐述技术方案，不应用于限制本发明的保护范围。
以上所述仅为本发明的较佳实施例而已，并不用以限制本发明，凡在本发明的精神和原则之内，所作的任何修改、等同替换等，均应包含在本发明的保护范围之内。
