This invention provides a method of causing proliferation of stem cells and their derivative cells and thus solves the cosmetic problems of wrinkles and sagging. Mechanical stress is applied to skin that includes sebaceous glands, thereby causing proliferation of stem cells and their derivative cells.

Devices for treating a subject's skin or lips and more particularly to device that enhances absorption of treatment media into tissue for cosmetic and therapeutic purposes.

A negative-pressure massage machine includes a main body and an embedded filter. The main body has a panel with an installing hole. The embedded filter includes a hollow cylinder and a filter element disposed in the hollow cylinder. The hollow cylinder is assembled or removed corresponding to the installing hole from the outside of the panel. Therefore, the ventilation may be performed with a filter assuredly when a user is operating, and the degree of dirtiness of the filter may be easily viewed and the filter may be replaced conveniently.

The present application discloses a surround pinch-kneading massager, comprising a housing and a massage drive mechanism, wherein a surface of the housing protrudes outward to form a soft bell-shaped cap, and the massage drive mechanism is arranged in the housing, wherein the massage drive mechanism is respectively drivingly connected to two opposite side walls of the bell-shaped cap, so that the massage drive mechanism drives the two opposite side walls of the bell-shaped cap to reciprocate and swing close to or away from each other to generate a pinch-kneading massage action, thereby enriching the massage methods of the massager and expanding the use range of the massager, so as to meet the diverse choices of users, thereby enhancing the user's sense of experience.

An adjustable gripper mechanism for male masturbation devices that allows for adjustment in gripper diameter based on individual variations in the girth of penises or based on individual preferences regarding tightness. In a preferred embodiment, the adjustable gripper mechanism comprises a left tubular portion, a right tubular portion, a hinge connecting the two tubular portions on one side of the tubular shape, a screw connecting the two tubular portions on the other side of the tubular shape, and a screw adjustment mechanism allowing for adjustment of the diameter of the tubular shape by turning of the screw. In some embodiments, the screw adjustment mechanism may be motorized, such that the gripper diameter may be adjusted electronically.

A method of providing sexual stimulation between first and second penises includes the steps of providing a body including first and second openings on a front face, wherein first and second channels extend into the body from the first and second openings, respectively, along first and second longitudinal axes, respectively, that tend toward each other within the body, wherein the first and second channels partially merge to form a chamber; inserting a first penis and a second penis into each of the first and second openings, respectively, such that the penises contact each other within the chamber of the body; and inserting the penises further into the chamber such that the penises move along the respective longitudinal axes and contact the inside surface of the chamber such that an underside of each penis is in contact with the other.

A male sexual stimulation device that provides a better user experience by combining a mechanical stroking mechanism with a spiraling sleeve that provides rotational stimulation and suctional stimulation to the stroking motion of the mechanical stroking mechanism. The spiraling sleeve is formed at least in part from an elastomeric material with ribbing molded into the interior of the sleeve at an angle to the linear axis of the spiraling sleeve such that elongation or shortening of the spiraling sleeve along the linear axis with a penis inserted therein causes a portion of the sleeve to twist about the linear axis.

The present invention discloses a pressure generator and a massager. The pressure generator includes a shell defining a first opening and a receiving space, a movable member extending into the receiving space and a drive device driving the movable member to reciprocally move within the receiving space. A gap is defined between the movable member and the inner wall of the shell.

Devices for treating a subject's skin or lips and more particularly to device that enhances absorption of treatment media into tissue for cosmetic and therapeutic purposes.

A treatment device for removing heat from subcutaneous lipid-rich cells of a subject having an actuator that provides mechanical energy to the tissue. The mechanical energy provided may include a vibratory component that can range between low and ultra-high frequencies, and such energy may include various combinations of two or more frequencies tailored to produce the desired effect on the subcutaneous tissue. Disruption of adipose tissue cooled by an external treatment device may be enhanced by applying mechanical energy to cooled tissue. Furthermore, such mechanical energy may impart a vibratory effect, a massage effect, a pulsatile effect, or combinations thereof on the tissue.
