Compression wave massage device

1. 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;

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 with 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, wherein:

the housing includes a channel formed in an external surface thereof and spaced apart from the first end of the one cavity of the one continuous chamber,

the socket includes a portion that is disposed on an exterior of the housing and a projection that engages and fits in the channel of the housing to secure the socket to the housing, and

the socket is made from a flexible material and further includes a section, located between the projection and the portion that conforms to fit over the first end of the one cavity of the one continuous chamber, wherein the section of the socket is spaced apart from the exterior of the housing thereby providing a void between the socket and the housing.

2. The compression wave massage device of claim 1 , wherein the socket is made from a soft, flexible material.

3. The compression wave massage device of claim 1 , wherein the socket is detachable from the housing by removing the projection from the channel of the housing and wherein the socket is separate and spaced apart from the flexible membrane.

4. 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 a 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 cavity at the second end to close the cavity at 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 cavity and away from the first end of the cavity to thereby generate a change of the volume of the 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 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;

a socket, physically connected to the housing and having a shape that conforms to fit over the first end of the cavity of the one continuous chamber and extend into the one continuous chamber to form a section of an inner lateral wall of the cavity of the one continuous chamber and wherein the socket is separate and spaced apart from the flexible membrane wherein:

the housing includes a channel formed in an external surface thereof and spaced apart from the first end of the one cavity of the one continuous chamber,

the socket includes a portion that is disposed on an exterior of the housing and a projection that fits in the channel of the housing to secure the socket to the housing, and

the socket is made from a flexible material and further includes a section, located between the projection and the portion that conforms to fit over the first end of the one cavity of the one continuous chamber, wherein the section of the socket is spaced apart from the exterior of the housing thereby providing a void between the socket and the housing; and

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.

5. The compression wave massage device of claim 4 , wherein the maximum pressure of each relative overpressure stage in reference to the normal air pressure is less than or equal to 10% of the value of the relative vacuum in reference to the normal air pressure.

6. The compression wave massage device of claim 4 , wherein the pressure field is a sinusoidal periodic pressure progression.
