Document Type and Number:
WIPO Patent Application WO/2024/106842
Kind Code:
A1
Abstract:
The present invention relates to an air filter structure, and a medical treatment apparatus using negative pressure, comprising same. The present invention reduces noise and vibration generated in an air line part when negative pressure is formed and released, and has a vacuum motor part that adjusts the direction of air such that, for both formation and release of negative pressure, the air is suctioned through a suction port and is discharged through a discharge port, and thus intervals of suctioning and discharging air are reduced to enable minimization of negative pressure repeating time, thereby greatly improving a treatment effect using negative pressure and obtaining various treatment effects.
