    A new injector-ventilation system using a modified respirator and injector-tube provides sufficient ventilation for laryngeal procedures. This apparatus is effective for direct laryngoscopy, diagnosis, and microsurgery of laryngeal diseases.

    Area of Science:

    • Medical Devices
    • Respiratory System Engineering
    • Laryngology

    Context:

    • Direct laryngoscopy for diagnosis and microsurgery of laryngeal diseases requires effective ventilation.
    • Existing jet-ventilation methods have limitations.
    • A novel apparatus system for injector-ventilation has been developed.

    Purpose:

    • To describe a newly-developed apparatus system for injector-ventilation.
    • To evaluate its application in direct laryngoscopy for laryngeal diseases.
    • To demonstrate its efficacy in providing sufficient ventilation.

    Summary:

    • The apparatus system comprises a modified respirator and an injector-tube, utilizing a jet-pump effect.
    • It has undergone laboratory and clinical testing, with over 250 patient applications.
