<p>MASSAGE UNIT A massage unit used for therapeutic purposes such as to loosen and mobilize bronchial secretions in humans; to improve blood circulation, and; to relax muscles, has a motor unit which transmits rotary motion to a cable engaged to an applicator unit. The applicator unit has a lower gripping portion which rotatably mounts an eccentric drive assembly which is drivingly coupled to the cable so as to be oscillated by cable rotation. An elbow-shaped tube extends upwardly and outwardly from the eccentric assembly so that an application pad mounted on the outer end of the elbow is moved in a circular path around an axis extending parallel to the surface of a patient's body and also parallel to the surface of an application pad, which allows the pad to impart a percussive and a directional massage stroke when it is applied to the body. The resultant force transmitted to the body has two components: one perpendicular to the body to loosen congestive material, and one force component parallel to the body to mobilize congested material in a selected direction.</p> |
