Design Error and Solution in Dry Powder Inhalers

In this study, the design errors of dry powder inhaler devices that have been used for many years, and their solutions depending on these errors were investigated. For this study, the most recommended inhaler devices by doctors, and the most frequently used by patients are provided. The effective use of the device and the problems that arise during its use have been observed on many patients, and a newly designed inhaler device has been developed considering the emerging problems. Observations have revealed hesitations for patients to switch to the newly designed device due to old habits. However, in the studies conducted on patients who switched to the new design device, it is seen that there is a serious time reduction in the treatment processes if the device is used correctly.
