With the increasing severity of air pollution, the number of patients suffering from respiratory diseases in China and abroad is increasing, and the medicines for the respiratory system gradually enter the visual fields of medicine enterprises, doctors and patients. Asthma (Asthma) and Chronic Obstructive Pulmonary Disease (COPD) are two diseases with the most serious influence on patients in respiratory diseases, and the world health organization statistics in 2013 show that respiratory diseases are leaped to the third highest mortality rate, and the mortality rate is as high as 14.09%. However, with the development of new technologies for pulmonary inhalation, patients will prefer to treat pulmonary diseases and bronchial diseases by inhalation. Recently, the mode of inhalation administration from metered dose aerosol inhalers (MDIs) has become the dominant route of choice for drugs involved in the treatment of respiratory diseases.
MDI type inhalers typically comprise an aerosol canister container, a metered dose dispensing valve and an inhalation actuator. The inhalation drive usually comprises a nozzle block, an interface for a dosage-dispensing valve and a user port. The metered dose dispensing valve is inserted into the actuator with the valve stem engaged with the nozzle block of the actuator. In use, a patient places their lips around the user's port and presses on 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 orifice.
In the prior art, some dose indicators or counters are designed to require electronics that add cost, deter 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 results in high cost, difficulty in assembly, and the need for complex dimensional tolerances. In some cases, it is necessary to redesign the dose indicator to be of a larger, bulkier and more cumbersome shape for the standard shape and size of the metered dose aerosol inhaler. In addition, the character size and definition of the display of such devices can be poor and difficult for a user to read. Some of the indicators are designed on the bottom, but the digital wheel disc needs to be at a specific angle, the number of parts is relatively large, and the design process is complicated. Some are designed as separate counter modules, not integrated in the drive, with a corresponding increase in production and matching costs.
