Description

This invention relates to a massage machine. Conventional massage machines use either blow-molded or welded airbags. Blow-molded airbags offer superior air supply and exhaust compared to welded airbags, but their rigidity results in a less tactile experience during treatment. Welded airbags, on the other hand, are more flexible than blow-molded airbags, resulting in a more tactile experience during treatment, but their air supply and exhaust capabilities are inferior. As an example of prior art related to the present invention, Patent Document 1 discloses an air massage device in which an air bladder is suspended and fixed to a concave frame. The frame has side vertical frame sections on both sides and an intermediate vertical frame section in the middle. The air bladder consists of a first layer of multiple air bladder sections and a second layer of air bladder sections. The first layer of air bladder sections is made of a flexible material. The second layer of air bladder sections is made of a harder material than the first layer of air bladder sections and is located on the back side of the first layer of air bladder sections. The multiple air bladder sections of the first layer are controlled to expand and contract to treat the calf when the second layer of air bladder sections is inflated.
