[0002] The percussion expectoration device is suitable for assisting postoperative and weak patients to enhance the ability to eliminate respiratory secretions such as sputum, improve the stagnant pulmonary blood circulation, and prevent and reduce the occurrence of respiratory complications. The existing percussion expectoration device includes a main unit and a percussion device. The percussion head is connected to the main unit through a flexible shaft. The percussion head includes an eccentric shaft and a percussion component. The motor in the main unit generates a rotational motion, and the flexible shaft transmits the rotational motion to the eccentric shaft. The rotation of the eccentric shaft drives the percussion component to rotate and generate vibration.
