Abstract

The present invention relates to a three-dimensional negative pressure stimulator module capable of performing customized composite stimulation for the improvement of skin functions that applies three-dimensional negative pressure stimulation as well as composite stimulation such as electric current stimulation, light stimulation, and thermal stimulation, which is helpful in improving functions of the skin, to skin compositively, and further has a function of sensing a skin state, thereby performing customized composite stimulation. The three-dimensional composite stimulator module includes: a negative pressure cup; and at least one diaphragm provided along the transmission path of the negative pressure of the negative pressure cup, wherein at least any one of negative pressure stimulation, light stimulation, thermal stimulation, and electrical stimulation is transmitted compositively to the skin or subcutaneous tissues.

Claims

1. A three-dimensional negative pressure composite stimulator assembly configured to perform customized composite stimulation for improvement of skin functions, the stimulator assembly comprising:

a motor and fan for generating negative pressure; and

a negative pressure cup, wherein the negative pressure cup comprises a housing having a cup shape;

a first diaphragm located inside the housing; and

a second diaphragm located above the first diaphragm inside the housing,

wherein the first diaphragm is configured to come into contact with a target region of a skin or to be placed adjacent thereto,

wherein the second diaphragm is configured to be spaced apart from the first diaphragm by a distance in a vertical direction in such a manner as to have no contact with the target region of the skin,

wherein the first diaphragm has a concave shape having a curvature adapted to physically limit a degree of maximum deformation of the target region of the skin by the negative pressure, while an open end of the housing is in tight contact with the skin, so that the skin deformedly protrudes toward a concave side of the first diaphragm,

wherein the second diaphragm has a concave shape having generally the same curvature as the curvature of the first diaphragm,

wherein the first diaphragm has at least one first vent formed on a surface thereof in such a manner as to pass air therethrough, and the second diaphragm has at least one second vent formed on a surface thereof in such a manner as to pass air therethrough, wherein the at least one first vent has a concave shape having a curvature on which a ventilation hole is formed,

wherein the first diaphragm has at least one concave element and at least one convex element disposed thereon to three-dimensionally adjust a deformation of the target region of the skin when the negative pressure is applied,

wherein the first diaphragm is connected with the housing at the inside of the housing so that the first diaphragm is configured to be adjusted in position vertically to control the degree of maximum deformation of the target region of the skin by the negative pressure, and

wherein the first diaphragm has an edge area on which at least one stimulation element for stimulating the target region of the skin or at least one sensing element for monitoring a condition of the target region of the skin is located.

2. The three-dimensional negative pressure composite stimulator assembly according to claim 1, wherein air flows from a lower portion of the negative pressure cup toward an upper portion thereof, so that the air inside the negative pressure cup is discharged therethrough to apply the negative pressure to the skin.

3. The three-dimensional negative pressure composite stimulator assembly according to claim 1, wherein the first diaphragm is configured to be separable from the housing so that the first diaphragm is located selectively to block or allow air flows to effectively transmit the negative pressure.

4. The three-dimensional negative pressure composite stimulator assembly according to claim 1, wherein each of the at least one stimulation element is an electrical stimulation element, a light stimulation LED element, or a laser element, and wherein each of the at least one sensing element is a temperature sensor, an impedance sensor, a blood flow sensor, or a pressure sensor.

5. The three-dimensional negative pressure composite stimulator assembly according to claim 1, wherein an amount of the negative pressure is controlled according to time.

6. The three-dimensional negative pressure composite stimulator assembly according to claim 1, wherein the at least one stimulation element is configured to apply both of a temporal three-dimensional stimulation and a spatial three-dimensional stimulation to the target region of the skin.
