  • Publication number: 20240342044
    Abstract: Devices, systems, and methods for percussion therapy of a patient's torso area provide percussive force to release and/or dislodge mucous from respiratory airways of a human patient. Such devices, systems, and methods may include a torso covering for securing to a patient's torso, percussive devices coupled to the torso covering, and an attachment assembly for supporting the torso covering. The percussive devices may include a percussion frame, an electromechanically actuated percussor for controlled movement between end positions, and resilient members attached to opposite ends of the percussion frame for assisting controlled movement of the percussor. The devices, systems, and methods disclosed herein provide efficient and comfortable high-frequency percussive force to a patient's torso, reducing stress on the patient and improving patient experience.
