Description

一种机械计数吸入气雾剂给药器A mechanical counting inhalation aerosol dispenser

技术领域technical field

本发明涉及一种气雾剂给药器,尤其涉及一种机械计数吸入气雾剂给药器。The invention relates to an aerosol dispenser, in particular to a mechanical counting inhalation aerosol dispenser.

背景技术Background technique

随着空气污染的日趋严重,国、内外患呼吸道疾病的患者日益增加,呼吸系统用药也逐渐进入药企、医生和患者的视野。哮喘(Asthma)、慢性阻塞性肺病(ChornicObstractivePlumonary Disease,COPD)是呼吸道疾病中对患者影响最严重的两大疾病,2013年世界卫生组织统计数据显示呼吸系统疾病已跃升为第三大高致死率的疾病,死亡率高达14.09%。然而随着新技术在肺部吸入给药取得很大的发展以后,广大患者也更青睐于采用吸入给药的方式来治疗肺部疾病以及支气管疾病。最近,来自定量气雾剂吸入器(MDI)的吸入给药方式已经成为涉及呼吸系统疾病的治疗的药物所选择的主要路径。With the increasingly serious air pollution, the number of patients suffering from respiratory diseases at home and abroad is increasing, and the use of respiratory system drugs has gradually entered the field of vision of pharmaceutical companies, doctors and patients. Asthma and chronic obstructive pulmonary disease (COPD) are the two most serious respiratory diseases affecting patients. In 2013, statistics from the World Health Organization showed that respiratory diseases have jumped to the third leading cause of death. disease, the mortality rate is as high as 14.09%. However, with the great development of new technologies in pulmonary inhalation drug delivery, the majority of patients also prefer to use inhalation drug delivery to treat pulmonary and bronchial diseases. More recently, inhalation delivery from metered-dose inhalers (MDIs) has become the primary route of choice for drugs involved in the treatment of respiratory diseases.

MDI类型的吸入器通常包括气雾剂储药罐容器、定量的剂量分配阀以及吸入驱动器。吸入驱动器通常包括喷嘴块、剂量分配阀的接口以及用户端口。将定量的剂量分配阀插入到驱动器中,此时阀杆与该驱动器的喷嘴块结合。在使用时,患者将他们的口唇置于用户端口周围并按压气雾剂容器的底部,使得容器相对于阀杆运动,从而通过喷嘴块小孔喷射一剂药物。MDI-type inhalers typically include an aerosol reservoir container, a metered dose-dispensing valve, and an inhalation driver. Inhalation drives typically include a nozzle block, an interface to a dose-dispensing valve, and a user port. The metered dose-dispensing valve is inserted into the driver, where the valve stem engages the nozzle block of the driver. In use, the patient places their lips around the user port and presses against the bottom of the aerosol container, causing the container to move relative to the valve stem, thereby ejecting a dose of medicament through the nozzle block aperture.

现有技术中,一些剂量指示器或计数器被设计为需要电子器件,所述电子器件增加成本、阻止使用者洗涤装置、可能具有电池寿命问题,并且就剂量计数器而言,它们的使用可能难以获得监管部门批准。此外,这些剂量指示器中的许多是复杂的,需要大量小型机械部件,这导致高成本、组装困难、以及对复杂的尺寸公差的需要。在一些情况下,需要为定量气雾吸入器的标准形状和大小的剂量指示器重新设计成更大、更庞杂并且更笨重的形状。此外,此类装置的显示器的字符大小和清晰度可能很差,使用者难以读取辨认。还有一些是将指示器设计在底部,但是其数字轮盘需要成特定的角度,并且零件相对较多,设计的过程也比较复杂。有些设计成单独的计数组件,没有集成在驱动器内,造成生产与匹配的成本相应升高。In the prior art, some dose indicators or counters are designed to require electronics that add cost, prevent the user from washing the device, may have battery life issues, and in the case of dose counters, their use may be difficult to obtain Regulatory approval. Furthermore, many of these dose indicators are complex, requiring a large number of small mechanical parts, which leads to high cost, difficulty in assembly, and the need for complex dimensional tolerances. In some cases, the standard shape and size of the dose indicator for metered-dose inhalers needs to be redesigned into larger, more bulky and bulky shapes. In addition, the character size and definition of the display of such devices may be poor and difficult for users to read. There are also some that design the indicator at the bottom, but the digital wheel needs to be at a specific angle, and there are relatively many parts, and the design process is also more complicated. Some are designed as separate counting components and are not integrated into the drive, resulting in a corresponding increase in production and matching costs.
