Description

[0001] A device for massaging the skin of the face, neck, décolleté, body and scalp

[0002] The invention relates to the technology of generating gas and / or gas-droplet jets for use in cosmetology for superficial relaxing and deep toning massage with the aim of normalizing muscle tone, lymphatic drainage, activating blood microcirculation and improving the quality and color of the skin, as well as achieving a lifting effect, namely: correction of the oval of the face, the "double" chin area and a reduction in the number of superficial and the severity of deep wrinkles.

[0003] The following devices are known from the prior art.

[0004] A skin treatment device comprising a tip assembly having a distal end and a proximal end, a cartridge containing an internal cavity, and a tip at the distal end of the tip assembly. The tip assembly includes a fluid supply conduit and a discharge conduit. The cartridge is further connected to the tip assembly, wherein the internal cavity of the cartridge is in fluid communication with the fluid supply conduit. The tip is further configured to contact the skin. The tip comprises a peripheral projection, a first opening for fluid communication with a fluid supply channel, a second opening for fluid communication with a waste channel, and an abrasive element (patent US20230018295, publication date January 19, 2023).

[0005] A skin treatment device comprising a console with a user input device and a handpiece assembly. The handle assembly is configured to treat skin. A fluid line provides fluid communication between the console and the handle assembly. A manifold system is connected to the console and controlled by the user input device. The manifold system is configured to releasably hold a plurality of fluid sources and to supply fluid from at least one of the plurality of fluid sources to the handpiece (patent US20230158282, publication date May 25, 2023).

[0006] A device for atomizing a liquid by means of a gas flow, in which the liquid enters a liquid container and can be atomized by means of a gas flow on a nozzle head of the atomizing device, which contains a nozzle needle, in which the supply device contains a check valve unit having at least one gas check valve for controlling the supply of gas to the supply device. According to the invention, the valve assembly can be connected to the first end of the cuvette holder for receiving a cuvette containing a liquid, wherein the valve assembly contains at least one outlet valve, which is opened by connecting the cuvette holder with the inserted cuvette to the valve assembly and, thus, releases the gas flow from the valve assembly through the cuvette holder to the nozzle head, which can be attached to the second end of the cuvette holder, in which at least one outlet valve can be actuated by the cuvette (patent EP2531246 A1, publication date 12.12.2012).

[0007] The disadvantages of known technical solutions include the low efficiency of the massage effect on the treated surface, due to the lack of the ability to exert sufficient force of the outlet gas flow on the treated surface.

[0008] The technical problem solved by the claimed invention is to increase the efficiency of a device for massaging the skin of the face, neck, décolleté, body and scalp.

[0009] The technical result consists in achieving the ability to work on deeper facial muscles, ligaments and fascia, mediated stimulation of skin receptors, relief of spasms from tense muscles and normalization of microcirculatory vascular tone, surpassing the effectiveness of manual massage, while reducing the time spent on the procedure.

[0010] The specified technical result is achieved by a device for massaging the skin of the face, neck, décolleté, body and scalp, comprising a gas medium supply system connected to a gas nozzle installed in the handle body, wherein the gas medium supply system comprises at least one compressor connected to the gas nozzle of the handle via at least one gas line with a gas medium pressure regulator, wherein the handle body comprises at least one output nozzle of the handle with an area S or a total area S of all output nozzles, configured to maintain a constant pressure in the gas line created by at least one compressor of the gas medium supply system, where the area S > k / P, where k is a constant coefficient, k=5, P is a constant pressure in the gas line, measured in atmospheres and created by at least one compressor,under conditions of the gas medium passing through the output nozzle of the handle with area S or through 2 or more output nozzles with a total area S onto the surface being treated,

[0011] An additional feature is that the device comprises a liquid medium delivery system configured to deliver the liquid medium through a handle onto the skin surface being treated, and the handle further comprises at least one liquid medium nozzle. The claimed invention is illustrated with graphics, including Fig. 1, a diagram illustrating the force exerted by a gas flow on the skin surface being treated, where 1 represents the epidermis, 2 represents the dermis and hypodermis, 3 represents the flow vortex, and 4 represents muscles.

[0013] Fig. 3 - photo demonstrating the effect of the gas flow on the treated skin surface during the procedure.

[0014] The claimed device consists of the following main components: gas supply system, handle, electronic control unit, gas pressure regulator.

[0015] Control is carried out using a pedal, mechanical handles and switches, or a touch screen, which, through a control device, interacts with electronic components: regulators, valves, etc.

[0016] The gas supply system consists of at least one compressor (5.1) connected to at least one gas main 6. Gas is supplied under pressure from 2 to 10 atmospheres, with an air supply volume from 75 to 5000 liters per minute at a pressure of 6-10 atmospheres (or from 150 to 10000 liters per minute at a pressure of 1.2 atmospheres).

[0017] The gas also has adjustable pressure, using a pressure regulator (not shown). Additionally, a receiver (5.2) for storing pressurized gas can be installed in the device, also connected to the compressor on one side and to the handle 7 via a gas line and control device on the other. Thus, the pressure in the receiver can be 10 atmospheres, while the handle is supplied with 6 atmospheres, 5 atmospheres, or 7.5 atmospheres, etc., using the pressure regulator.

[0018] The receiver operates on the following principle: a pressure switch is installed on the receiver and set to preset values, for example, a lower limit of 7.5 atmospheres and an upper limit of 8 atmospheres. Thus, if the pressure in the receiver drops below the set 7.5 atmospheres, the switch activates at least one compressor and increases the gas pressure in the receiver to 8 atmospheres. If 8 atmospheres is reached, the compressor or compressors are deactivated. Thus, the pressure in the receiver is maintained in a constant range from 7.5 to 8 atmospheres, or from 9.5 to 10 atmospheres, or from 8.5 to 9 atmospheres, etc.

[0019] Accordingly, the control unit monitors the pressure inside the receiver using a sensor. If it reaches the upper limit, for example, 8 atmospheres, the control unit switches the relay, and at least one compressor begins idle operation without load, for example, for 5 seconds, to reduce the pressure in its piston blocks to approximately 1 atmosphere (i.e., without load). After this, if the pressure in the receiver remains above the lower limit, for example, 7.5 atmospheres, at least one compressor stops without load. This eliminates unnecessary fluctuations and surges in at least one compressor during shutdown.If the device consumes air and the pressure in the pressure regulator decreases below the specified values, then at least one compressor is either switched on by the control device, or, if it has not yet been switched off, for example, within 5 seconds allocated for releasing pressure from the piston blocks, the relay switches, directing the flow of compressed air from at least one compressor back into the receiver, and it again begins to accumulate pressure up to the set upper limit, for example, 8 atmospheres.

[0020] At least one gas line, through a receiver and a pressure regulator, is connected to at least one gas nozzle formed inside the air line of the handle body.

[0021] Additionally, in a particular embodiment, the claimed invention comprises a system for supplying a liquid medium with a container with a liquid medium (liquid or preparation) and at least one liquid line connected to the handle.

[0022] For this purpose, at least one liquid nozzle is provided outside or inside the gas line of the handle body for supplying a liquid medium through the handle to the skin surface being treated.

[0023] Gas from at least one gas nozzle is supplied inside the handle into the air line under a pressure of 4-10 atmospheres.

[0024] However, for a more effective effect on the skin, the air flow force should exceed 0.6 Newton (i.e. more effective than the effect of the cosmetologist’s fingers), but not exceed 100 Newton due to the possibility of injury and overdrying of the skin.

[0025] Due to the increased air supply of over 75 l / min, a higher force of action is created on the treated surface, which, as a result, primarily increases the massage effect (lymphatic drainage, muscle toning), and, if the device has a liquid line, contributes to improved effects on moisturizing and cleansing the skin.

[0026] Therefore, the area of ​​the handpiece's outlet nozzle, or the total area of ​​the outlet nozzles, must provide the necessary gas flow capacity to achieve the required force on the skin, ranging from 0.6 N to 100 N. The claimed device is designed to achieve a massage effect in the form of normalized muscle tone, lymphatic drainage, lifting, and improved skin tone and quality on the face, neck, décolleté, and other areas of the body and scalp. This effect is comparable to manual cosmetic massage and superior in effectiveness, all without the therapist's excessive effort. This facilitates the therapist's work, reduces procedure time, and increases efficiency.

[0027] As a result of the conducted research, it was found that the result of massage (normalization of muscle tone, lymphatic drainage, lifting, improvement of skin tone and quality) is achieved if the force of impact on the skin surface is a concentrated gas flow (in a particular case, an air stream), which has an impact force on the treated skin surface of at least 0.6 Newton at a distance of 10 mm from the outlet nozzle to the treated skin surface.

[0028] A distance of 10 mm from the outlet nozzle to the skin surface being treated is used as the reference distance, which determines the force of the gas flow exiting the handpiece outlet nozzle. A shorter distance (7 mm, 5 mm, 2 mm, etc.) produces a lower force (the difference is no more than 10%) but greater pressure on the skin surface due to a smaller area of ​​action. Conversely, as the distance from the outlet nozzle to the skin surface being treated increases to 70 mm, the force increases (the difference is no more than 10%), but the pressure on the skin surface decreases due to an increased area of ​​action, as the gas flow jet has a conical shape. If the distance from the outlet nozzle to the skin surface being treated increases beyond 70 mm, the force on the skin surface being treated begins to decrease, and the pressure on the skin surface continues to decrease due to an increased area of ​​action.

[0029] This gives the specialist additional options for adjusting the pressure on the treated skin surface by simply changing the distance from the handpiece's outlet nozzle to the skin being treated. This allows for variability in the massage effect on the treated areas, specifically the ability to vary the force of the mechanical action of air pressure and vibration waves on the treated skin areas.

[0030] Research also revealed that if the force applied to the treated skin surface is less than 0.6 Newtons, the effectiveness of this procedure is less than that of manual cosmetic massage for lymphatic drainage, lifting, and normalizing muscle tone in the face, neck, décolleté, and other areas of the body. Measurements of the gas flow force applied to the treated surface were conducted under the following conditions:

[0031] 1. The device supplied a gas flow that maintained a stable pressure of 4 to 10 atmospheres within the gas line. This pressure remained constant even when the gas flow exited the handle's outlet nozzle of a specified area, thanks to the corresponding flow rate of liters per minute required to maintain constant pressure within the gas line. The results are presented in Table 1.

[0032] 2. Measurements of the gas flow's impact force on the workpiece were performed using a dynamometer with the gas flow being supplied from the handpiece's outlet nozzle, which was located 10 mm from the workpiece. This distance was chosen as the optimal one, demonstrating the gas flow's impact force to within + / - 10%. As the distance decreases below 10 mm, the dynamometer readings decrease by about 10%. As the distance increases to 70 mm, the dynamometer readings increase by approximately 10%, after which they begin to decline due to the outlet nozzle being too far from the workpiece.

[0033] The values ​​of the force exerted by the gas flow on the surface being treated, obtained using a dynamometer, for various combinations of pressure and outlet nozzle area, are indicated within Table 1 itself in Newtons.

[0034] Table 1 highlights the threshold values ​​that exceed 0.6 Newton, thus revealing a pattern in the relationship between the combination of pressure inside the gas pipeline and the area of ​​the outlet nozzle of the manipulator (or the total area of ​​all the outlet nozzles of the manipulator).

[0035] In order to be able to use this data in the design and creation of the device, Table 2 was created, within which the coefficient k = P * S is calculated, where P is the pressure in atmospheres inside the gas line of the device, S is the area of ​​the output nozzle of the handle in square mm.

[0071] When comparing Table 1 and Table 2, it was found that for the values ​​of pressure and area of ​​at least one nozzle, at which the coefficient k = 5 is obtained in Table 2, the force of action in Table 1 is equal to or greater than 0.6 Newton, which is required to achieve the ability to work on deeper facial muscles, ligaments and fascia, mediate stimulation of skin receptors, relieve spasms from tense muscles and normalize the tone of the vessels of the microcirculatory bed in a shorter period of time, compared with the prototype or manual massage.

[0072] Therefore, when selecting the area S of the output nozzle of the handpiece (or the total area of ​​all output nozzles) to achieve the specified technical result, it can be expressed by the following formula S > k / P, where

[0073] P is the constant pressure in the gas line, measured in atmospheres and created by at least one compressor, under conditions of the gas medium passing through the outlet nozzle of the manipulator onto the surface being treated, and

[0074] k is a constant coefficient, k=const, k=5 and characterizes the lower limit of the force of the desired impact on the treated skin surface by the gas flow coming out of the output nozzle of the manipulator.

[0075] With these parameters, the force of the gas flow on the treated skin surface at a distance of 10 mm from the output nozzle of the handle to the treated surface will always be greater than or equal to 0.6 Newton, which is necessary to ensure that the effectiveness of the massage result for the purpose of normalizing muscle tone, lymphatic drainage, lifting, improving the quality and tone of the skin is higher than the effectiveness of manual cosmetic massage performed by a specialist.

[0076] Thus, when a gas or gas / liquid flow is supplied through a gas or gas and liquid line, the gas and / or gas and liquid flows are supplied through the corresponding nozzles into the internal volume of the manipulator and the gas flow entering under a pressure of 4-10 atmospheres through the output nozzle of the manipulator is sprayed onto the area of ​​skin being treated with an impact force of 0.6 N to 100 N.
