Description

Suction handpiece and skin beauty device equipped therewith

[0001] The present invention relates to a suction handpiece and a skin beauty device having the same, and more particularly, to a suction handpiece that prevents an air passage from being blocked by a treatment cream during vacuum suction, and a skin beauty device having the same.

[0002] In general, skin beauty devices that utilize negative pressure achieve a therapeutic effect by placing a suction handpiece on a specific area of ​​the patient's skin and then using a pump to provide negative pressure to the skin. Their use is gradually increasing due to the diversification of current skin treatment procedures.

[0003] Medical devices that use negative pressure for treatment include vacuum massage devices, fat-dissolving devices that use vacuum to suck the patient's skin and then apply ultrasound to the sucked area to break down fat, and cupping devices that use skin suction to achieve oriental medicine treatment effects.

[0004] In addition, the suction handpiece can achieve a massage effect using negative pressure, including an RF electrode, and a skin beauty effect using an RF electrode.

[0005] RF electrodes (radio frequency) are used to treat by heating the skin and the underlying tissues. They are used to increase the skin temperature after cryolipolysis for obesity treatment to restore the skin, and for skin treatment that heats the skin and the underlying tissues to cause collagen contraction or induce a wound healing response.

[0006] More specifically, RF electrodes (radio frequency) are being used in various ways, such as skin remodeling / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins, by applying electrical signals to collagen in the lower dermis to induce contraction or wound healing.

[0007] The suction handpiece is connected to a vacuum device and a suction tube to form negative pressure inside, and alternately forms negative and positive pressures within the negative pressure-forming space in contact with the skin through the suction tube.

[0008] In addition, the stone-cutting handpiece can be used to apply treatment cream to the skin to enhance the effect of the treatment. However, in this case, there was a problem in that the treatment cream applied to the skin during the treatment was sucked into the air path of the suction tube through the suction port along the inner side of the negative pressure-forming space due to negative pressure.

[0009] In particular, in the case of suction handpieces equipped with RF electrodes (radio frequency), when electrically stimulating the skin with RF electrodes (radio frequency), it is essential to apply treatment cream to reduce pain and minimize side effects. Therefore, cases frequently occur where the treatment cream is sucked into the air passage of the suction tube through the suction port along the inner side of the negative pressure forming space during the treatment.

[0010] There was a problem in that if the treatment cream was sucked into the air passage of the suction tube, the negative pressure was not applied evenly, which reduced the treatment effect, and the treatment cream remaining in the air passage hardened and blocked the suction tube passage.

[0011] In addition, there was a problem that the treatment cream sucked into the air passage lowered the durability of the vacuum device, and if it blocked the suction tube passage, the treatment would stop during the treatment, and it took time and money to resolve this.

[0012] In the case of conventional suction handpieces equipped with RF electrodes (radio frequency), a replaceable filter is installed in the suction port to prevent the treatment cream from being sucked into the air passage during the treatment. However, there is the inconvenience of having to replace the filter periodically, and there is a problem that it is difficult to maintain the negative and positive pressure at a constant set pressure due to a decrease in negative and positive pressure caused by the filter, and a decrease in negative and positive pressure caused by foreign substances clogging the filter.

[0013] A prior patent related to the present invention is Korean Patent Publication No. 2021-0147811, “Treatment device using a vacuum cup” (published on December 7, 2021).

[0014] The purpose of the present invention is to provide a suction handpiece that prevents treatment cream from being sucked into an air passage by negative pressure during treatment without a filter, and a skin beauty device equipped with the same.

[0015] Another object of the present invention is to provide a suction handpiece capable of efficiently generating negative pressure and positive pressure within a negative pressure forming space and a skin beauty device having the same.

[0016] In order to achieve the above-described object of the present invention, one embodiment of a suction handpiece according to the present invention is characterized by including a handpiece body having a negative pressure forming space open to a surface in contact with the skin, an air suction pipe member positioned within the handpiece body and connecting a suction port of the negative pressure forming space and a vacuum device of a control main body, and a cream movement guide member mounted to the suction port within the negative pressure forming space and guiding a treatment cream moving along the inner surface of the negative pressure forming space toward the suction port to flow downward and blocking the cream from flowing into the suction port.

[0017] In the present invention, the cream movement guide member can be detachably coupled to the suction port.

[0018] In the present invention, a connecting tube portion to which the cream movement guide member is detachably connected may be formed to protrude from the suction port at the upper portion of the negative pressure forming space.

[0019] In the present invention, the cream movement guide member may include a coupling protrusion coupled to the suction port and a cream support portion formed to surround the outer circumference of the coupling protrusion, on which the treatment cream moving downward along the outer surface of the coupling protrusion is placed.

[0020] In the present invention, a connecting pipe part to which the cream movement guide member is detachably connected is formed to protrude from the suction port at the upper portion of the negative pressure forming space, and the cream movement guide member can be connected by having the connecting pipe part inserted into the interior of the connecting protrusion.

[0021] In the present invention, the end of the above-mentioned coupling protrusion can be positioned so as to be in contact with the upper surface of the negative pressure forming space.

[0022] In the present invention, the cream support portion may be formed as a first inclined surface with an upper surface inclined downwards toward the end side to move the cream for treatment downwards.

[0023] In the present invention, the cream support portion may be formed with a second inclined surface whose lower surface collects air toward the suction port.

[0024] In the present invention, the cream receiving portion may be formed as a first inclined surface with an upper surface inclined downwards to move the cream for treatment downwards, and a second inclined surface with a lower surface inclined downwards to collect air toward the suction port.

[0025] In the present invention, a cream storage unit for storing the treatment cream that has come down along the connecting protrusion unit may be positioned on the upper surface of the cream support unit.

[0026] In the present invention, the upper portion of the above-mentioned connecting protrusion may be provided with a sloped surface for guiding the cream movement that has risen along the inner surface of the negative pressure forming space to the outer surface of the above-mentioned connecting protrusion.

[0027] In the present invention, the cream movement guide member is connected to the upper side of the negative pressure forming space so as to be able to move up and down, and is elastically supported by a spring member so as to be able to move up and down when negative pressure and positive pressure are alternately and repeatedly formed within the negative pressure forming space.

[0028] In the present invention, the cream movement guide member is connected so that the coupling protrusion penetrates the upper surface of the negative pressure forming space and can move up and down, and a spring support member that elastically supports the spring member is positioned so as to protrude on the inner surface of the coupling protrusion, and the spring member is positioned between the spring support member and the upper surface of the negative pressure forming space to elastically support the cream movement guide member.

[0029] In the present invention, the spring support portion is positioned at the lower end side on the inner side of the coupling projection portion, and a spring insertion groove portion into which the spring member is inserted is provided so that when the cream movement guide member is raised and lowered, the upper end side is supported by the upper surface of the negative pressure forming space, thereby limiting the range of lifting and lowering movement.

[0030] In the present invention, the upper surface of the negative pressure forming space is connected by the connecting projection part penetrating therethrough, and a pipe part for guiding the up and down movement of the connecting projection part is positioned so as to protrude, and a stopper protrusion part that catches the upper end side of the connecting projection part can be positioned so as to protrude outward.

[0031] In the present invention, an inflow blocking O-ring portion may be positioned on the inner surface of the ascending and descending guide tube to block the treatment cream positioned on the outer surface of the connecting protrusion from flowing inward.

[0032]

[0033] In order to achieve the above-described object of the present invention, one embodiment of a skin beauty device according to the present invention includes a control body having a suction handpiece and a vacuum device connected to the suction handpiece and connected to a negative pressure forming space of the suction handpiece, and the suction handpiece is characterized in that it is an embodiment of the suction handpiece according to the present invention.

[0034] The present invention prevents the treatment cream from being sucked into the air passage by negative pressure during the treatment, thereby preventing the air passage from being blocked, thereby ensuring operational stability, increasing the durability of the vacuum device, and reducing the cost and time required to repair the air passage blocked by the treatment cream.

[0035] The present invention prevents the treatment cream from being sucked into the air passage by negative pressure during the treatment without a filter, thereby improving the treatment effect by maintaining the negative pressure and positive pressure at a constant set pressure during the treatment, and has the effect of significantly reducing the cost and time required for equipment management since there is no need to replace or manage the filter.

[0058] FIG. 1 is a schematic diagram illustrating a skin beauty device having a suction handpiece (10) according to the present invention, and FIG. 2 is a cross-sectional view illustrating one embodiment of a suction handpiece (10) according to the present invention.

[0059] Referring to FIGS. 1 and 2, one embodiment of a suction handpiece (10) according to the present invention and a skin beauty device equipped therewith will be described in detail below.

[0060] A skin beauty device equipped with a suction handpiece (10) according to the present invention includes a control body (20) equipped with a suction handpiece (10) according to the present invention and a vacuum device connected to the suction handpiece (10) and connected to a negative pressure forming space (100a) of the suction handpiece (10).

[0061] The suction handpiece (10) according to the present invention has a negative pressure forming space (100a) that is opened to a surface that is placed on the skin and comes into contact with the skin, and may include an RF electrode unit (400) that comes into contact with the skin and applies an RF electric signal to the skin.

[0062] The control main body (20) is connected to the suction handpiece (10) by a handpiece cable body (30) including a control cable and an air intake / exhaust line, and includes a vacuum device that can repeatedly form negative pressure and positive pressure within the negative pressure forming space (100a) of the suction handpiece (10).

[0063] The control cable is a cable for controlling the operation of the RF electrode unit (400), and the air intake / exhaust line includes a pipe member that is connected to the vacuum device of the control main body unit (20) and sucks in air within the negative pressure forming space (100a) or supplies air into the negative pressure forming space (100a).

[0064] The control body (20) and the handpiece cable body (30) can be modified in various ways from a known example of a known negative pressure treatment device that controls the operation of a suction handpiece (10) equipped with an RF electrode, and a more detailed description thereof will be omitted.

[0065]

[0066] Meanwhile, one embodiment of a suction handpiece (10) according to the present invention includes a handpiece body (100) having a negative pressure forming space (100a) open to a surface that comes into contact with the skin.

[0067] The handpiece body (100) has a negative pressure forming space (100a) that is open to the lower side, i.e., the contact surface that comes into contact with the lower side.

[0068] The handpiece body (100) includes a cup part (110) in which a negative pressure forming space (100a) is formed inside, and the cup part (110) has a shape including a roof part (111) having a hemispherical dome shape and a cylindrical part (112) located on the lower side of the roof part (111), and the lower side of the cylindrical part (112) is connected to a contact surface, which is the lower surface of the handpiece body (100), and has a structure in which it comes into contact with the skin.

[0069] In addition to this, the negative pressure forming space (100a) can be implemented by being modified in various ways into a known shape in the suction handpiece (10), so a more detailed description is omitted.

[0070] Additionally, a suction port (100b) is positioned in the negative pressure forming space (100a) to form negative pressure by sucking in the air inside or to form positive pressure by supplying air inside.

[0071] As an example, the suction port (100b) is located at the center of the negative pressure forming space (100a), that is, at the center of the roof portion (111). By being located at the center of the roof portion (111), air within the negative pressure forming space (100a) can be evenly sucked in, and air can be evenly supplied within the negative pressure forming space (100a).

[0072] The suction port (100b) is connected to the vacuum device of the control main body (20) through the air suction tube member (200) located within the handpiece body (100).

[0073] The air intake pipe member (200) may be configured as a single line integral with the air intake / exhaust line of the handpiece cable body (30), or may have a structure that is separable from the air intake / exhaust line of the handpiece cable body (30).

[0074] In addition, as an example, the RF electrode part (400) is positioned in multiple numbers on the contact surface of the handpiece body part (100), and as an example, it has a ring-shaped electrode shape surrounding the entrance of the negative pressure forming space (100a).

[0075] Additionally, the RF electrode unit (400) may include a plurality of RF electrodes having a ring shape and positioned spaced apart from each other on the contact surface of the handpiece body unit (100).

[0076] As an example, the plurality of RF electrode parts (400) are ring-shaped electrodes each having a different diameter, and are positioned spaced apart from each other at the contact surface of the handpiece body part (100) with the same width or different widths.

[0077] Although not shown, the RF electrode portion (400) may be positioned on the inner surface of the negative pressure forming space (100a) and may be positioned to contact a portion of the skin that protrudes into the negative pressure forming space due to negative pressure.

[0078] In summary, the RF electrode part (400) is positioned so as to be in contact with the skin on the handpiece body part (100) and applies an RF electric signal to the contacted skin.

[0079] The RF electrode unit (400) is a known RF electrode that is used in various ways, such as skin remodeling / resurfacing, wrinkle removal, and treatment of sebaceous glands, hair follicles, fatty tissue, and spider veins, by applying an electric signal to the collagen in the lower dermis to induce contraction or wound healing. A more detailed description thereof will be omitted.

[0080] A control wire section (not shown) is provided within the handpiece body section (100) to connect the RF electrode section (400) and the control main body section (20) to control the operation of the RF electrode section (400).

[0081] The control wire section may be configured as a single line integral with the control cable of the handpiece cable body (30), or may have a structure that is separable from the control cable of the handpiece cable body (30).

[0082] A cream movement guide member (300) is installed in the suction port (100b) of the negative pressure formation space (100a) to guide the treatment cream moving along the inner surface of the negative pressure formation space (100a) toward the suction port (100b) downward and block it from flowing into the suction port (100b).

[0083] The cream movement guide member (300) moves the treatment cream applied to the skin during the treatment along the inner surface of the negative pressure forming space (100a) toward the suction port (100b) formed on the upper surface and then moves downward, i.e., toward the skin.

[0084] The cream movement guide member (300) is provided in the suction port (100b) located on the upper side of the negative pressure formation space (100a) and prevents the treatment cream moved to the upper side along the negative pressure formation space (100a) from being sucked into the suction port (100b) by flowing downward along the outer surface.

[0085] The treatment cream may be a negative pressure treatment cream used during negative pressure treatment, or an RF treatment cream used during RF treatment.

[0086] Typically, during RF treatment, RF treatment cream is applied to reduce pain and minimize side effects. During the treatment, the RF treatment cream can move along the inner side of the negative pressure forming space (100a) toward the suction port (100b) and be introduced into the suction port (100b).

[0087] In a suction handpiece (10) that performs RF treatment and negative pressure treatment simultaneously, the cream movement guide member (300) blocks the RF treatment cream that moves toward the suction port (100b) along the inner surface of the negative pressure formation space (100a) during the treatment from flowing into the suction port (100b).

[0088] The cream moving guide member (300) includes a coupling protrusion (310) coupled to the suction port (100b) and a cream receiving member (320) formed to surround the outer circumference of the coupling protrusion (310) so that the treatment cream moved downward along the outer surface of the coupling protrusion (310) is placed on the upper surface.

[0089] As an example, the coupling protrusion (310) has a tubular shape with a hollow portion extending in the longitudinal direction and is fitted into the interior of the suction port (100b) or fitted into the exterior of the suction port (100b) to be coupled and have a structure that can be easily separated.

[0090] In more detail, in the upper part of the negative pressure forming space (100a), a coupling pipe (120) to which a cream movement guide member (300) is detachably coupled is formed to protrude from the suction port (100b), and the cream movement guide member (300) is coupled by having the coupling pipe (120) inserted into the interior of the coupling protrusion (310).

[0091] In addition, the end of the connecting projection (310) is positioned so as to be in contact with the upper surface of the negative pressure forming space (100a), i.e., the upper surface of the cup portion (110), thereby preventing the treatment cream from flowing in and becoming stuck between the end of the connecting projection (310) and the negative pressure forming space (100a).

[0092] The connecting tube (120) is inserted into the hollow portion of the connecting projection (310) and connected so that the diameter of the suction port (100b) does not decrease, and the end of the connecting projection (310) is positioned so as to be in contact with the upper surface of the negative pressure forming space (100a), so that when the treatment cream that has moved to the upper surface of the negative pressure forming space (100a) moves downward along the outer surface of the connecting projection (310), the treatment cream moves downward smoothly without being caught between the end of the connecting projection (310) and the negative pressure forming space (100a).

[0093] That is, the cream movement guide member (300) is coupled to the suction port (100b) and includes a coupling protrusion (310) that protrudes below the suction port (100b) and moves the treatment cream, which has been moved to the upper surface of the negative pressure formation space (100a), downward along the outer surface.

[0094] In addition, a cream receiving portion (320) is provided on the outer circumference of the connecting projection (310) on which a treatment cream that moves downward is positioned on the upper surface.

[0095] The cream support portion (320) prevents the treatment cream from flowing into the hollow portion of the combination projection portion (310) when air is sucked in through the suction port (100b) at the end of the combination projection portion (310) by expanding the area of ​​the end side of the combination projection portion (310) that moves the treatment cream downward.

[0096] The cream receiving portion (320) is formed with an area that prevents the treatment cream positioned on the outer periphery from flowing back toward the suction port (100b) by the suction pressure through the suction port (100b).

[0097] For example, the cream receiving portion (320) has a diameter that is at least twice the diameter of the connecting protrusion (310) or the diameter of the suction port (100b) to prevent the cream for treatment from flowing back toward the suction port (100b).

[0098] As an example, the cream support portion (320) is formed in a circular shape that surrounds the outer circumference of the joining projection portion (310).

[0099] In addition, the upper surface of the cream support (320) is formed as an inclined surface with the end side facing downward, thereby guiding the treatment cream placed on the upper side to move toward the end side.

[0100] In addition, the lower surface of the cream support (320) is formed as a sloped surface that widens from the suction port (100b) side toward the end side.

[0101] That is, the cream receiving portion (320) has a funnel shape in which the upper surface is formed as a first inclined surface (320a) that slopes downwards to move the cream for treatment downwards, and the lower surface is formed as a second inclined surface (320b) that collects air toward the suction port (100b).

[0102] The cream support (320) guides the air in the negative pressure forming space (100a) toward the suction port (100b) through the second slope (320b) on the lower side when forming a negative pressure so that it can be smoothly inhaled, and when forming a positive pressure, the air supplied into the negative pressure forming space (100a) is supplied in a wide direction so that when forming negative pressure and positive pressure repeatedly, the preset negative pressure and positive pressure can be reached as quickly as possible, and the cycle of positive pressure and negative pressure can be shortened.

[0103] In addition, the cream support member (320) guides the treatment cream that has moved to the upper surface along the connecting projection member (310) to move downward along the inclined first slope (320a) and drop it from the end side.

[0104] The cream holder (320) can minimize the replenishment of the treatment cream during the treatment by smoothly moving the treatment cream downward through the first inclined surface (320a) on the upper side, dropping it back onto the skin, and returning it to its original position, and can minimize the amount of the treatment cream remaining in the negative pressure forming space (100a) after the treatment.

[0105] In summary, the treatment cream applied to the skin moves toward the suction port (100b) located on the upper surface of the negative pressure formation space (100a) along the inner surface of the negative pressure formation space as negative pressure and positive pressure are alternately and repeatedly generated within the negative pressure formation space (100a) during the treatment.

[0106] Then, the treatment cream is moved to the suction port (100b) side, and then guided downward along the outer surface of the connecting protrusion (310) positioned protruding from the suction port (100b) to move onto the cream receiving portion (320), and then moves downward along the first inclined surface (320a) from the upper surface of the cream receiving portion (320) to fall onto the skin again.

[0107]

[0108] FIG. 3 and FIG. 4 are cross-sectional views illustrating another embodiment of a suction handpiece (10) according to the present invention, and referring to FIG. 3 and FIG. 4, a cream storage unit (321) for storing treatment cream that has come down along the coupling protrusion unit (310) is positioned on the upper surface of the cream receiving unit (320), so that treatment cream that has come up along the inner surface of the negative pressure forming space (100a) after use is stored in the cream storage unit (321), thereby preventing it from flowing into the suction port (100b).

[0109] In the case of a procedure to remove waste matter within the skin, the waste matter within the skin is mixed together with the treatment cream, and in the case of the treatment cream mixed with waste matter, instead of falling back onto the skin and being reused, it is stored in the cream storage portion (321) formed on the upper surface of the cream receiving portion (320), and after the procedure, the cream movement guide member (300) is separated from the suction port (100b), washed, and then reassembled for use.

[0110] The cream moving guide member (300) may have a hopper shape with a diameter that increases toward the upper side, as shown in FIG. 3, and may have a structure in which a cream storage portion (321) is formed within the hopper.

[0111] In addition, the cream movement guide member (300) may have a structure in which a cream storage portion (321) is formed in a sunken shape around the perimeter of the coupling protrusion (310) on the upper surface, as shown in FIG. 4.

[0112] The cream moving guide member (300) can be formed in various shapes with a cream storage section (321) in which the treatment cream can be stored by lowering the outer surface of the joining protrusion (310) on the upper surface.

[0113] In addition, the cream movement guide member (300) is manufactured in various shapes suitable for the type of treatment, and is detachably coupled to the suction port (100b), so that a shape suitable for the treatment can be coupled to the suction port (100b) for use.

[0114] The treatment cream applied to the skin moves toward the suction port (100b) located on the upper surface of the negative pressure formation space (100a) along the inner surface of the negative pressure formation space as negative pressure and positive pressure are alternately and repeatedly generated within the negative pressure formation space (100a) during the treatment.

[0115] Then, the treatment cream is moved to the suction port (100b) side, and then guided downward along the outer surface of the connecting protrusion (310) positioned protruding from the suction port (100b) to move onto the cream receiving portion (320), and then moves downward along the first inclined surface (320a) from the upper surface of the cream receiving portion (320) to fall onto the skin again.

[0116]

[0117] In addition, the upper part of the joining protrusion (310) is provided with a slope (323) for guiding the cream for treatment that has risen along the inner surface of the negative pressure forming space (100a) to the outer surface of the joining protrusion (310).

[0118] The slope (323) for guiding the movement of the cream is formed in a cone shape with a diameter that gradually increases from the upper end of the joining projection (310) and wraps around the outer circumference of the suction port (100b) to adhere to the upper surface of the negative pressure forming space (100a).

[0119] The slope (323) for guiding the cream movement guides the treatment cream that has risen toward the suction port (100b) along the inner side of the negative pressure forming space (100a) to the outer side of the joining protrusion (310), thereby facilitating the movement of the treatment cream and preventing the treatment cream from getting caught in a specific part and accumulating during movement.

[0120]

[0121] In addition, FIG. 5 is a cross-sectional view illustrating another embodiment of a suction handpiece (10) according to the present invention, and referring to FIG. 5, a cream movement guide member (300) is coupled to the upper side of a negative pressure forming space (100a) so as to be able to move up and down, and is elastically supported by a spring member (500) so as to move up and down when negative pressure and positive pressure are alternately and repeatedly formed within the negative pressure forming space (100a).

[0122] In more detail, the cream movement guide member (300) is connected so that the coupling protrusion (310) can move up and down by penetrating the upper surface of the negative pressure forming space (100a), and a spring support member (311) that elastically supports the spring member (500) is positioned so as to protrude on the inner surface of the coupling protrusion (310), and the spring member (500) is positioned between the spring support member (311) and the upper surface of the negative pressure forming space (100a) to elastically support the cream movement guide member (300).

[0123] The spring support portion (311) is located at the lower end side on the inner side of the coupling projection portion (310) and is provided with a spring insertion groove portion into which a spring member (500) is inserted, so that when the cream movement guide member (300) is raised and lowered, the upper end side is supported by the upper surface of the negative pressure forming space (100a), thereby acting as a stopper to limit the range of lifting and lowering movement.

[0124] In addition, a connecting projection (310) is connected through the upper surface of the negative pressure forming space (100a), and a rising and falling guide pipe (130) that guides the up and down movement of the connecting projection (310) is positioned so as to protrude, and a stopper projection (312) that is caught on the upper side of the connecting projection (310) is positioned so as to protrude outward.

[0125] The stopper protrusion (312) acts as a stopper to limit the downward movement range when the upper side of the cream movement guide member (300) is caught on the upper side of the ascending and descending guide pipe (130) when descending.

[0126] The cream moving guide member (300) moves up and down by alternating between negative and positive pressures, and when moving up, the spring support member (311) moves between a position where it touches the upper surface of the negative pressure forming space (100a) and a position where the stopper protrusion (312) moves between a position where it touches the moving up and down guide pipe member (130).

[0127] In addition, an inflow blocking O-ring (600) is positioned on the inner surface of the ascending and descending guide tube (130) to block the treatment cream located on the outer surface of the joining protrusion (310) from flowing inward.

[0128] The O-ring (600) for blocking inflow is located at the lower end of the inner side of the ascending and descending guide pipe (130) to block the treatment cream from flowing into the inner side of the ascending and descending guide pipe (130).

[0129] When negative pressure is generated in the negative pressure forming space (100a), the air sucked in, that is, the cream movement guide member (300) is raised and lowered by the negative pressure, and when positive pressure is generated, the air discharged through the suction port (100b) is lowered by the positive pressure.

[0130] When the cream moving guide member (300) is raised and lowered, the treatment cream that moves along the outer surface of the joining protrusion (310) is pushed downward from the upper surface of the negative pressure forming space (100a) and moves more quickly to the cream receiving portion (320).

[0131] The treatment cream is moved to the outer surface of the joining projection (310) and then moves downward more quickly and smoothly when the cream movement guide member (300) is raised and lowered, thereby preventing the cream from solidifying and accumulating due to stagnation in movement at a specific part.

[0132] In addition, vibration is generated in the cream receiving portion (320) by the up-and-down movement of the cream moving guide member (300), and thus, the treatment cream moving on the first inclined surface (320a), which is the upper surface of the cream receiving portion (320), can be smoothly and quickly moved downward along the first inclined surface (320a) by the vibration and fall back onto the skin.

[0133] The cream movement guide member (300) moves up and down when negative pressure and positive pressure are generated, and moves the treatment cream that rises up the suction port (100b) side along the inner surface of the negative pressure forming space (100a) back down quickly to resupply it onto the skin, thereby enabling rapid circulation of the treatment cream within the negative pressure forming space (100a) during the treatment, and enabling the treatment to be performed without the need to replenish the treatment cream due to loss of the treatment cream.

[0134]

[0135] The present invention prevents the treatment cream from being sucked into the air passage due to negative pressure during the treatment, thereby preventing the air passage from being blocked, thereby ensuring operational stability, increasing the durability of the vacuum device, and reducing the cost and time required to repair the air passage blocked by the treatment cream.

[0136] The present invention prevents the treatment cream from being sucked into the air passage by negative pressure during the treatment without a filter, thereby improving the treatment effect by maintaining the negative pressure and positive pressure at a constant set pressure during the treatment, and significantly reduces the cost and time required for equipment management by eliminating the need to replace or maintain the filter.

Furthermore, those skilled in the art will appreciate that numerous modifications and variations are possible without departing from the scope of the present invention.
