ABSTRACT:
To eliminate excessive secretion from the lungs of a patient, percussion action of therapeutically effective frequency and amplitude is imparted to the patient's chest area. A bed top (10) is rotatably mounted on a base (20, 30). The bed top includes a frame (11), a head supporting section (17), a chest supporting section (16), and a lower body supporting section (15). A percussor (50, 52) is connected with the chest supporting section for providing the percussive action. The head supporting section includes upstanding shoulder engaging portions to either side thereof to engage the patient's shoulders to prevent the patient from being vibrated off the bed when the head end of the patient is tipped downward. The chest supporting section is mounted in vibrational isolation to the frame to reduce the amount of percussive action received by the patient's head and other portions of the body which may tend to cause nausea. The chest supporting section is mounted higher than the head and lower body supporting sections to focus the percussive action on the patient's chest area. The chest supporting section transfers the percussion action generally in proportion to the weight and body mass of the supported patient. A ball screw actuator (40) provides an effective one-way transmission for rotating the bed top relative to the base.
