Compression wave massage device

A compression wave massage device for body parts, comprising:

• a pressure field generation device consisting essentially of a flexible membrane and one continuous chamber, wherein the one continuous chamber includes one cavity having (i) a volume, (ii) a first end including an opening configurable for physical placement over a body part, and (iii) a second end, located opposite the first end and distanced therefrom, and wherein portions of the flexible membrane are physically attached and fixed to the one cavity at the second end to close the one cavity at the second end, wherein a cross-section of the one cavity is approximately constant from the first end to the second end;
• a drive device including a motor, physically coupled to the flexible membrane, to, in operation, deflect the flexible membrane in a reciprocal motion in a direction towards the first end of the one cavity and away from the first end of the one cavity to thereby generate a change of the volume of the one cavity of the one continuous chamber between a minimum volume and a maximum volume such that a pressure field is generated at the first end of the one cavity of the one continuous chamber, wherein:
• (i) a ratio of the change in volume of the one cavity of the one continuous chamber to the minimum volume is greater than 1/10, and (ii) the ratio of the change in volume of the one cavity to the minimum volume is less than 1;
• a housing, wherein the drive device and the pressure field generation device are disposed within the housing;
• and
• a socket, physically engaged within the housing and having a shape that conforms to fit over the first end of the one cavity of the one continuous chamber to attach to an exterior surface of the housing and extends into the one continuous chamber to form a section of an inner lateral wall of the one cavity of the one continuous chamber.

• a housing, wherein the drive device and the pressure field generation device are disposed within the housing;
• wherein, in operation, the pressure field generation device and the drive device cooperate to provide a pressure field having a pattern of relative vacuum stages and relative overpressure stages which are modulated on a reference pressure, wherein a maximum pressure of each relative overpressure stage in reference to normal air pressure is below a value of a relative vacuum in reference to the normal air pressure.
