Description

TECHNICAL FIELD

[0001] The present application relates to an intelligent dosing device, in particular to an intelligent dosing device integrating gas aerosol dosing and breath detection. BACKGROUND

[0002] With the increasing seriousness of air pollution, the number of patients suffering from respiratory diseases is increasing both at home and abroad, and respiratory system drugs have gradually entered the field of view of pharmaceutical companies, doctors and patients. Asthma and chronic obstructive pulmonary disease (COPD) are the two most serious diseases among respiratory diseases, and the World Health Organization's statistics in 2013 show that respiratory diseases have become the third most deadly disease, with a mortality rate of 14.09%. However, with the great development of new technologies in pulmonary inhalation dosing, the general public also prefers to use inhalation dosing to treat lung diseases and bronchial diseases. Recently, inhalation from a metered dose inhaler (MDI) has become the preferred route for the administration of other drugs for the treatment of non-primary bronchial diseases.

[0003] MDI type inhalers generally include an aerosol container, a metered dose dispensing valve, and a drive inhalation dosing device. The drive inhalation dosing device generally includes a nozzle block, an interface for the metered dose dispensing valve, and a user port. The metered dose dispensing valve is inserted into the drive, at which point the valve stem is coupled to the nozzle block of the drive. In use, the patient places their lips around the user port and presses the bottom of the aerosol container, causing the container to move relative to the valve stem, thereby ejecting a dose of medication through the nozzle block orifice.

[0004] The coordination between the duration of inhalation and the ejection time of the medication is critical to the proportion of the medication that is effectively inhaled to the affected area when a user uses an inhalation aerosol. When a dose of medication is ejected, either inhaling too early or too late will not allow enough medication to reach the affected area, resulting in lower than expected efficacy. The correct coordination of inhalation time and medication ejection time is the key to the correct use of inhalation aerosols by users.

[0005] The patient with respiratory disease not only needs drug treatment, but also needs to perform respiratory detection, because the respiratory detection data is an important basis for determining the severity of the disease and the effect of drug treatment. The current drug delivery device can only realize the purpose of drug delivery, and cannot perform respiratory detection. The intelligent drug delivery device integrating aerosol drug delivery and respiratory detection is designed, which is implanted with electronic circuit board, temperature sensor, humidity sensor, photosensitive sensor and airflow sensor, so that the drug delivery device has the functions of drug record and respiratory detection. The electronic circuit board can also connect the drug delivery device with the mobile terminal or remote server, so as to realize intelligent drug management. The cooperation between the calculated drug spraying time and the actual inhalation time of the user can help the user to judge whether the inhalation coordination is correct, so as to improve the use of the user on the inhalation aerosol, and increase the effectiveness and expected use effect of the drug.
