[0002] At present, there are two scientifically proven effective breast augmentation methods in the world, namely surgical breast augmentation and negative pressure breast augmentation system; other drugs, creams, essential oils and conventional massage methods have little effect on breast augmentation, and some are even harmful to the human body. Surgical breast augmentation requires anti-infection, swelling reduction and long-term massage after surgery, and there are also many complications such as bacterial infection, which is a high risk. In addition, people who do not meet the conditions for surgery cannot use surgical breast augmentation.

[0003] In human history, the principle of negative pressure traction tissue expansion has been widely used by people as early as several centuries ago. It is also widely used in the field of modern medicine and has become an important entry tool and method for health therapy and pathological treatment. For example, negative pressure induction of labor in Western medicine, negative pressure detoxification technique of cupping in traditional Chinese medicine, limb lengthening technology, facial repair, negative pressure liposuction, etc., all use the negative pressure mechanism; negative pressure is used for breast augmentation, which has also been clinically verified for 30 years. Since Neumann reported the soft tissue expander in 1957, through continuous improvement and promotion, negative pressure traction tissue expansion has become one of the conventional treatment methods in plastic surgery. The negative pressure breast augmentation device does not use other materials, does not require injections, medications or smears, and can safely and effectively improve the chest curve.

[0004] The patent with the file number CN205626431U discloses a physical breast enlargement instrument, including a gasket, a plastic cup, a microcomputer controller and a high-elastic bra, wherein the gasket is annular and surrounds the breast, and has an annular hat-brim shape outward, and an annular soft edge on the inner circle, and the plastic cup is shaped like a bra cup, and its lower edge is tightly connected with the upper end of the gasket; the inner side of the plastic cup has an air vent and a plastic air duct; the microcomputer controller has components such as an air pressure sensor, a signal amplifier, and a vacuum pump, which are responsible for sucking the air in the cup, sensing and regulating the pressure in the cup; the utility model forms a closed environment for breast tissue through the gasket, the plastic cup and the high-elastic bra, and uses the microcomputer controller to suck the air in the plastic cup to form a constant negative pressure around the breast, accelerate local blood circulation and thus achieve the purpose of promoting breast tissue hyperplasia, mainly for breast tissue defects such as congenital breast hypoplasia, breast atrophy after lactation, and bilateral breast asymmetry.

[0005] Although the above scheme achieves negative pressure breast augmentation, on the one hand, in order to ensure the negative pressure effect, the cup and the skin are usually in a relatively sealed state, and body fluids are difficult to discharge, resulting in moisture inside the cup, affecting comfort, and the setting may cause skin diseases; on the second hand, the strength of the cup is difficult to guarantee, and once deformation occurs, it will affect the breast augmentation effect; on the other hand, the working mode of the air pump is relatively single, and it is difficult to meet the needs of different groups of people.

[0043] like Figure 1 , 2 As shown, the present invention provides a negative pressure breast augmentation device, including a main structure 1, a fixing belt 2 and a negative pressure control structure 3; the main structure 1 is covered on the human breast and forms a negative pressure space together with the skin; the fixing belt 2 is connected to the main structure 1 to position the main structure 1 on the human body; the negative pressure control structure 3 is connected to the negative pressure space to control the negative pressure.

[0044] like Figure 3-6 As shown, the main structure 1 includes a cup 11, a reinforcement part 12, a liquid guide groove 13 and a skin-contacting pad 14. The cup 11 is made of a material with poor air permeability to ensure the negative pressure effect. A vent hole is provided on the cup 11, and the vent hole is connected to the negative pressure control structure 3; the reinforcement part 12 is arranged on the cup 11 to improve the strength and rigidity of the cup 11; the liquid guide groove 13 is arranged on the inner surface of the cup 11 close to the skin, and is a groove structure. The end of the groove structure is connected to the vent hole, so that the groove and the vent hole are connected. The sweat of the human body or the body fluid in the postoperative breast wound can quickly reach the vent hole through the liquid guide groove 13, and be discharged from the cup 11 together with the gas, so as to maintain a dry environment in the cup 11 and improve the wearing comfort; the skin-contacting pad 14 is arranged along the part where the cup 11 contacts the skin, and is a flexible pad, which further improves the wearing comfort.

[0045] Two cups 11 are provided corresponding to the breasts, and the edges thereof are provided to fit the skin through the skin-fitting pad 14, and a gap is provided between the middle and the skin, so that the cups 11 and the skin together form a relatively sealed negative pressure space. The cups 11 can adopt a shape that adapts to the curve of the human breast, for example, its cross section can be provided in a teardrop shape, an elliptical shape, etc. In some embodiments, the cups 11 are provided in a hemispherical shape. The cups 11 are made of hard plastic and are used to support the overall shape.

[0046] In some embodiments, the cup 11 is placed on the breast and the surrounding soft tissue, including accessory breast. Under long-term traction, the constant negative pressure can effectively absorb the free fat at the edge of the breast cells and transform it into breast tissue, thereby eliminating accessory breast and enlarging the chest line.

[0047] In some embodiments, a massage part is provided on the inner surface of the cup 11 close to the skin corresponding to the acupuncture points of the breast, and the massage part is a local protruding structure. There are 9 meridians running on the breast, such as the hand Taiyin lung meridian, the foot Yangming stomach meridian, the foot Taiyin spleen meridian, the hand Shaoyin heart meridian, the foot Shaoyin kidney meridian, the hand Jueyin pericardium meridian, the foot Shaoyang gallbladder meridian, the foot Jueyin liver meridian and the conception meridian. There are many meridians running on the breast. Properly massaging the breast meridians and acupuncture points can promote the circulation of meridians and the circulation of qi and blood, and can promote the maturation of breasts. Massaging the meridians on the breast can also prevent and treat breast diseases, such as mastitis, breast rock, nipple rupture and milk stasis.

[0048] The reinforcement part 12 is arranged on the outer surface of the cup 11 away from the skin and is a convex strip structure, which improves the strength and rigidity of the cup 11 when the weight change is small. Optionally, the convex strip structure is staggered to form a pattern to improve the aesthetics of the main structure 1.

[0049] The liquid-conducting grooves 13 are arranged in a staggered manner to form a pattern, thereby improving the aesthetics of the main structure 1 .

[0050] In some embodiments, the liquid guide grooves 13 are arranged at intervals along the circumference of the cup 11, and the groove body is in an arc shape. The liquid guide grooves 13 extend from the edge of the cup 11 to the center and form a cross, so that each liquid guide groove 13 can be directly or indirectly connected to the vent. The massage part is the groove side wall edge of the liquid guide groove 13, that is, it is naturally formed when the liquid guide groove 13 is opened, and corresponds to the breast acupuncture points. At this time, the massage part corresponds to the liquid guide groove 13 in an arc shape, which can better adapt to the breast acupuncture points and meridians, and under the suction action of the air pump 36, the arc shape can better adapt to the breast curve, improve the massage effect and user experience; in addition, the massage part formed at the intersection of the liquid guide grooves 13 has a greater pressure and can achieve linkage massage.

[0051] In some embodiments, the massage part can also be a separately provided raised structure, which can be provided as a line type corresponding to the meridians, or as a raised point structure, so as to achieve partial or all breast meridians or acupoint massage. The raised structure is staggered with the notch of the liquid guide groove 13 to avoid affecting the liquid guide effect. Optionally, the raised structure is an arc-shaped raised structure, which extends from the edge of the cup to the center and forms a cross.

[0052] In some embodiments, the reinforcement part 12 is arranged on the outer surface of the cup corresponding to the liquid guide groove 13, that is, the convex strip structure of the reinforcement part 12 is arc-shaped, extending from the edge of the cup 11 to the center and forming a cross. The convex strip structure of the reinforcement part 12 is convenient for the user to adjust the position of the cup 11 by hand, and can also avoid the influence of the groove of the liquid guide groove 13 on the strength of the overall structure. The natural angle formed at the cross position is more convenient for holding and external force fixing and pressing.

[0053] The skin-adhering pad 14 is a silicone gel pad and is a translucent structure, which is convenient for observing the shaping of the chest soft tissue. The skin-adhering pad 14 is sticky and can be precisely attached to the shape around the human breast, so that the cup 11 and the skin contact part are well sealed to ensure the negative pressure effect.

[0054] The fixing belt 2 is connected to the cup 11. When wearing, the fixing belt 2 is used to adjust and fix the cup 11, so that the cup 11 that absorbs the chest tissue with negative pressure can be pulled to a precise position on the human body and fixed. The fixing belt 2 can be a fixing belt of an existing bra, which can achieve the position adjustment and fixation of the cup 11, so it is not described in detail.

[0055] like Figure 7 , 8 As shown, the negative pressure control structure 3 includes an air pump 36 and an air pipe 31; the air pipe 31 is connected to the vent hole of the cup 11; the air pump 36 is connected to the negative pressure space inside the cup 11 through the air pipe 31; the air pump 36 draws air to form a negative pressure, which will not interrupt the capillary blood flow and provide a stable, soft and homogeneous pulling force on the breast surface.

[0056] The gas delivery pipe 31 is a silicone tube.

[0057] In some embodiments, the air pump 36 is powered by a battery and has a solenoid valve disposed thereon. The negative pressure control structure 3 further includes a controller, which is in communication with the solenoid valve, and controls the solenoid valve through the controller, thereby controlling the air intake of the air pump 36 to achieve different negative pressure adjustments.

[0058] In some embodiments, the negative pressure control structure 3 also includes a shell 32 and a connecting portion 33. The air pump 36, battery and controller are all arranged in the shell 32. The shell 32 protects the air pump 36 and other components, which facilitates the installation and connection of each component with the cup 11. One end of the connecting portion 33 is connected to the cup 11, and the other end is connected to the shell 32 to fix the shell 32.

[0059] Furthermore, the negative pressure control structure 3 also includes a pressure sensor, a display screen 34, a control button 35 and a speaker; the pressure sensor is used to detect the air pressure value output by the air pump 36 and is communicated with the controller; the display screen 34 is communicated with the controller for displaying the air pressure value output by the air pump 36; the speaker is communicated with the controller for voice broadcasting the air pressure value output by the air pump 36; the control button 35 is communicated with the controller for issuing control instructions to the controller.

[0060] The speaker includes two states: on and off. When in the on state, its volume can be adjusted by the controller.

[0061] The air pump 36 realizes different working modes by adjusting the output air pressure value. In some embodiments, the working modes of the air pump 36 include a constant mode and a fluctuation mode. The constant mode includes a constant pressure state and a boosted pressure state; the fluctuation mode includes a fluctuating boosted pressure state, a constant fluctuation state, a rapid fluctuation state, and an ups and downs fluctuation state. By adjusting the suction and pulling change frequency and suction and pulling force, the breasts are prompted to move at a high speed to achieve a massage breast enhancement effect, thereby matching and adapting to the needs of people with different body shapes.

[0062] Specifically, Fig. 9 As shown, in the constant pressure state, the working air pressure of the air pump 36 remains unchanged; in the boosting state, the working air pressure of the air pump 36 increases linearly; in the fluctuating boosting state, the working air pressure of the air pump 36 increases in a fluctuating manner, and the fluctuation frequency is the same; in the constant fluctuation state, the working air pressure of the air pump 36 fluctuates, and the fluctuation amplitude and frequency are the same; in the rapid fluctuation state, the working air pressure of the air pump 36 fluctuates, and the fluctuation amplitude and frequency are the same, and the fluctuation frequency is greater than the fluctuation frequency of the constant fluctuation state; in the fluctuating fluctuation state, the working air pressure of the air pump 36 fluctuates periodically. In the above-mentioned air pressure fluctuation state, the air pressure fluctuation frequency and air pressure fluctuation amplitude can be selected according to different breast sizes and human body tolerance.

[0063] In constant mode, the air pump 36 can evacuate the inside of the cup 11, so that the breast and the tissues around the breast are sucked and squeezed into the cup 11, so that the breast and the tissues around the breast are gathered together. Under long-term traction, the constant negative pressure can effectively absorb the free fat on the edge of the breast cells and cultivate it into breast tissue, thereby treating breast sagging, breast deformity, breast asymmetry, and eliminating accessory breasts to enlarge the chest line.

[0064] In the wave mode, when the vacuum pressure in the cup 11 increases, the breast and the tissues around the breast are sucked together and squeezed, and when the vacuum pressure in the cup 11 decreases, the breast and the tissues around the breast will relax. In the process of fluctuating pressure rise and fall, the breast is squeezed and relaxed in the cup 11, achieving a certain breast massage function. Massage and kneading can help improve breast blood circulation, relieve discomfort such as breast pain, improve good blood circulation and promote the health of breast tissue. The massage function can help improve the shape and firmness of the breast, thereby achieving a fuller breast effect.

[0065] When the air pump 36 is in a constant mode, the massage part performs pressing massage on the acupoints; when the air pump 36 is in a wave mode, the massage part performs kneading massage on the acupoints, providing different massage modes and massage intensities for the user.

[0066] The negative pressure control structure 3 is arranged between the two cups 11, and the connecting part 33 is arranged on both sides of the shell 32 and connected with the corresponding cups 11 to fix the shell 32 between the two cups 11. Optionally, the connecting part 33 is an adjustable belt with an adjustable length to facilitate the use and wearing of different people.

[0067] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
