Vest type vibrating expectoration instrument

The Whole Chest Oscillating Expectoration Machine uses "High Frequency Chest Wall Oscillation" (HFCWO) technology to send pulse signals through the host, causing the inflatable vest (or chest strap) to repeatedly produce high-frequency oscillations at high speed, forming a directional autonomous sputum discharge effect, promoting the respiratory tract and lungs The secretions of the deep leaves relax, liquefy, and fall off, allowing the phlegm to move from the bronchi to the main trachea, and then be expelled from the body through coughing or Oscillating Expectoration Machine. Used in conjunction with external treatment with traditional Chinese medicine or aerosol inhalation, it can effectively enhance the phlegm-reducing effect and is deeply loved. Everyone loves it. It can be seen that the Expectoration Machine is very comfortable to use. In future use, we will continue to learn and strive to improve the medical experience.
