AI Technical Summary

Technical Problem

The prior art nebulized drug delivery treatment is difficult to achieve accurate drug delivery, and because mucosa is attached to the surface wall of tissues such as trachea and bronchial, it is difficult for atomized drugs to reach the lesions directly, resulting in low treatment effects.

Method used

A deep-deployable drug delivery device is designed, including a flexible catheter, aeration tube, an atomization tube, an electric air pump, an air pump, an atomizer, an isolated air bag, a telescopic air bag, a scraping air bag and an annular nozzle. By extending the catheter into the trachea, the airbag expansion is controlled and the up and down movement of the airbag is scraped off, and the lesions are isolated and the mucus is removed to ensure that the atomized liquid reaches the lesions directly.

Benefits of technology

Accurate drug administration is achieved, avoiding the overflow of atomized liquid, improving the therapeutic effect, and reducing waste of liquid. At the same time, by scraping the up and down movement of the airbag, we ensure that the atomized liquid is evenly distributed to the lesion, which improves the treatment effect.

[0002] Respiratory diseases refer to various diseases that affect the human respiratory system. The respiratory system includes the respiratory tract (nose, pharynx, larynx, trachea and bronchi at all levels) and lungs. For such diseases, atomization is a common method for treating respiratory diseases. It mainly converts drugs into tiny particles and directly delivers them into the respiratory tract to achieve local treatment effects.

[0015] Furthermore, the isolation airbag is an annular airbag; the isolation airbag spacing is set on the outer wall of the front end of the catheter; the spacing between the two isolation airbags ranges from 5 to 20 mm;

[0016] Furthermore, the gas injection tube 1 connects the two isolation air bags and the scraping air bag;

[0017] Furthermore, an annular silicone scraping layer is provided at the largest diameter of the scraping airbag; an air pump is used to inject air into the scraping airbag to expand the scraping airbag so that the annular silicone scraping layer abuts against the inner wall of the trachea, and an electric air pump is used to control the extension and contraction of the telescopic airbag, driving the scraping airbag to move up and down to scrape the mucus on the inner wall of the trachea, so that the atomized liquid medicine can directly reach the lesion;
