    Area of Science:

    • Pulmonary Medicine
    • Biomedical Engineering

    Background:

    • Nebuliser therapy is a key treatment for asthma, but conventional devices often require compressed air.
    • Existing nebuliser designs face challenges in ensuring consistent fluid delivery for effective aerosolization.

    Purpose of the Study:

    • To develop and evaluate a new nebuliser device for bronchodilator administration in asthma patients.
    • To assess the performance of a novel vertical spinning disc nebuliser compared to a standard compressed air nebuliser.

    Main Methods:

    • A prototype nebuliser utilizing a vertically spinning disc within a fluid reservoir was designed.
    • The efficacy of the new device was compared against a conventional compressed air nebuliser in 8 asthma patients.
    • Improvements in spirometry values served as the primary metric for performance comparison.

    Main Results:

    • The novel spinning disc nebuliser demonstrated comparable performance to conventional compressed air nebulisers.
    • Both devices resulted in similar improvements in spirometry values for the participating asthma patients.
    • The new device successfully overcomes the challenge of constant fluid delivery to the spinning disc.

    Conclusions:

    • The developed vertical spinning disc nebuliser is a viable alternative for bronchodilator delivery in asthma management.
    • This new device offers a potentially more accessible and convenient option, reducing reliance on compressed air systems.
    • Further research may explore the long-term efficacy and patient acceptance of this innovative nebuliser technology.
