Description

Electrode module and oral grounding electrode device including the same

[0001] The present invention relates to an electrode module and an oral grounding electrode device including the same.

[0002] Recently, skin care devices have been developed to remove wrinkles, restore skin elasticity, and remove sebum.

[0003] There are several types of skin care devices, including those that deliver ultrasound to skin tissue (HIFU type), those that deliver electric current to skin tissue (especially, high frequency, RF type), and those that irradiate laser light to skin tissue (optical type).

[0004] Here, the type that delivers current to the skin transmits high-frequency waves generated by the electrodes to the skin, inducing coagulative necrosis. In this way, skin undergoing coagulative necrosis can experience the removal of collagen and elastic fibers, and the formation of new collagen and elastic fibers. Furthermore, skin undergoing coagulative necrosis can improve pigmentation, acne scars, and wrinkles.

[0005] Meanwhile, conventional oral grounding electrode devices apply current to the oral surface and attach a return pad to the abdomen or back. However, the current applied to the oral surface flows transversely (laterally) from the oral surface, resulting in inefficient transmission of the current within the oral skin tissue and a reduced current stimulation effect.

[0006] The present invention has been devised to solve the above-described problems, and the purpose of the present invention is to provide an electrode module and an oral grounding electrode device including the same, which can enhance the stimulation effect of oral skin by applying current by utilizing oral skin as a passage through which current passes.

[0007] The problems to be solved by the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the description below.

[0008] An electrode module according to one embodiment of the present invention includes a first ground electrode and a second ground electrode respectively disposed on the inner surface of each cheek of the oral cavity; and a connecting part connecting the first ground electrode to a power module and connecting the second ground electrode to a power module.

[0013] In addition, the electrode module may include a first ground electrode and a second ground electrode respectively disposed on the inner surface of each cheek of the oral cavity; and a connecting part connecting the first ground electrode to a power module and connecting the second ground electrode to a power module.

[0014] In addition, the first ground electrode is configured in plurality, the plurality of first ground electrodes are connected integrally, the second ground electrode is configured in plurality, the plurality of second ground electrodes are connected integrally, and the impedance measuring part can measure the impedance of the plurality of first ground electrodes and the plurality of second ground electrodes, respectively.

[0015] In addition, the impedance measurement part may generate an alarm when at least one of the plurality of measured values ​​measured from the plurality of first ground electrodes and the plurality of second ground electrodes falls outside a preset range.

[0016] In addition, the device may further include a first elastic member disposed on the inner surface of the first ground electrode facing the teeth and pressurizing the first ground electrode toward the inner surface of one side of the oral cavity when inflated; and a second elastic member disposed on the inner surface of the second ground electrode facing the teeth and pressurizing the second ground electrode toward the inner surface of the other side of the oral cavity when inflated.

[0017] In addition, the device may further include a fluid injection part that injects fluid into at least one of the first elastic member and the second elastic member to expand the member.

Furthermore, terms defined in commonly used dictionaries are not to be interpreted ideally or excessively unless explicitly and specifically defined otherwise.

[0034] Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings.

[0035] Figure 1 is a schematic diagram showing an electrode module according to one embodiment of the present invention.

[0036] As illustrated in FIG. 1, an electrode module (100) according to one embodiment of the present invention can be inserted into the inner surface of both cheeks of the oral cavity of a living body.

[0037] The electrode module (100) may include a first ground electrode (10), a second ground electrode (20), and a connection part (30).

[0038] The first ground electrode (10) may be placed on the inner surface of the left cheek of the oral cavity. For example, the first ground electrode (10) may be configured in multiple units, and the multiple first ground electrodes (10) may be connected as one unit. As another example, referring to FIG. 1, the first ground electrode (10) may be configured in two units, and the two first ground electrodes (10) may be connected as one unit. In this case, one of the two first ground electrodes (10) may be placed between the inner surface of the left cheek of the oral cavity and the maxillary teeth, and the other of the two first ground electrodes (10) may be placed between the inner surface of the left cheek of the oral cavity and the mandibular teeth. As another example, the multiple first ground electrodes (10) may be physically connected to each other as one unit, but may be electrically connected to the power module (300). For this purpose, an insulator may be interposed between two adjacent first ground electrodes (10). In addition, since the two first ground electrodes (10) are foldably connected to each other, the two first ground electrodes (10) can be bent toward the upper and lower sides of the inner surface of the left cheek of the oral cavity, respectively.

[0039] For example, the first ground electrode (10) can be detachably coupled to the second ground electrode (20) described later.

[0040] For example, the first ground electrode (10) may include an elastic material. This first ground electrode (10) can be easily inserted into the inner surface of the left cheek of the oral cavity through the mouth, and can be deformed into a shape corresponding to the inner surface of the left cheek of the oral cavity while inserted into the inner surface of the left cheek of the oral cavity. However, the shape of the first ground electrode (10) is not limited thereto, and various shapes can be applied for easy placement in the oral cavity.

[0041] For example, when current is applied from the power module (300) to the outer surface of the left cheek of the mouth, a monopolar type can be applied in which the electric energy between the power module (300) and the first ground electrode (10) is circulated to the skin of the left cheek of the mouth.

[0042] The second ground electrode (20) may be placed on the inner surface of the right cheek of the oral cavity. For example, the second ground electrodes (20) may be configured in multiple units, and the multiple second ground electrodes (20) may be connected as one unit. As another example, referring to FIG. 1, the first ground electrodes (10) may be configured in two units, and the two first ground electrodes (10) may be connected as one unit. In this case, one of the two first ground electrodes (10) may be placed between the inner surface of the right cheek of the oral cavity and the maxillary teeth, and the other of the two first ground electrodes (10) may be placed between the inner surface of the right cheek of the oral cavity and the mandibular teeth. As another example, the multiple second ground electrodes (20) may be physically connected to each other as one unit, but may be electrically connected to the power module (300). For this purpose, an insulator may be interposed between two adjacent second ground electrodes (20). In addition, since the two second ground electrodes (20) are foldably connected to each other, the two second ground electrodes (20) can be bent at an angle toward the upper and lower sides of the inner surface of the right cheek of the oral cavity, respectively.

[0043] For example, the second ground electrode (20) may include an elastic material. Accordingly, the second ground electrode (20) can be easily inserted into the inner surface of the right cheek through the mouth, and can be deformed into a shape corresponding to the inner surface of the right cheek while inserted into the inner surface of the right cheek.

[0044] For example, when current is applied from the power module (300) to the outer surface of the right cheek of the mouth, a monopolar type can be applied in which the electric energy between the power module (300) and the second ground electrode (20) is circulated to the skin of the right cheek of the mouth.

[0045] The connecting part (30) can connect the first ground electrode (10) to the power module (300) and the second ground electrode (20) to the power module (300). Accordingly, the power module (300) can implement a large-area electric energy transfer area on the skin of the cheeks on both sides of the oral cavity by supplying power to a plurality of first ground electrodes (10) and a plurality of second ground electrodes (20) that are each connected through the connecting part (30).

[0046] The connecting part (30) may include a plurality of first cables (31) and a plurality of second cables (32).

[0047] A plurality of first cables (31) can each connect a plurality of first ground electrodes (10) to a power module (300).

[0048] A plurality of second cables (32) can connect a plurality of second ground electrodes (20) to the power module (300).

[0049] For example, a plurality of first cables (31) and a plurality of second cables (32) exposed to the outside of the oral cavity may be covered by a cable cover (33). That is, the cable cover (33) surrounds the plurality of first cables (31) and the plurality of second cables (32) exposed to the outside of the oral cavity, and may serve to collect the plurality of first cables (31) and the plurality of second cables (32).

[0050] The first elastic member (40) is placed on the inner surface of the first ground electrode (10) facing the teeth, and can press the first ground electrode (10) toward the inner surface of the left side of the oral cavity when expanded. Details thereof will be described later. (See FIGS. 8 and 9)

[0051] The second elastic member (50) is placed on the inner surface of the second ground electrode (20) facing the teeth, and can press the second ground electrode (20) toward the inner surface of the right side of the oral cavity when expanded. Details thereof will be described later. (See FIGS. 8 and 9)

[0052] FIG. 2 is a schematic diagram showing a first wearable part (60) and a second wearable part (70) of an electrode module (100) according to one embodiment of the present invention, and FIG. 3 is a schematic diagram showing a state in which the first wearable part (60) and the second wearable part (70) of an electrode module (100) according to one embodiment of the present invention are worn inside the oral cavity.

[0053] As illustrated in FIGS. 2 and 3, an electrode module (100) according to one embodiment of the present invention may further include a first wearable part (60) and a second wearable part (70).

[0054] The first wearable part (60) is coupled to the inner surface of the first ground electrode (10) facing the teeth, and can be worn between the upper and lower teeth. For example, if the first ground electrode (10) is composed of two, the first wearable part (60) can be coupled between the two first ground electrodes (10).

[0055] The second wearable part (70) is connected to the inner surface of the second ground electrode (20) facing the teeth at a distance from the first wearable part (60), so that it can be worn between the upper and lower teeth. For example, if the second ground electrode (20) is composed of two, the second wearable part (70) can be connected between the connecting portions of the two second ground electrodes (20).

[0056] Hereinafter, an oral grounding electrode device according to one embodiment of the present invention will be described. This will be described primarily with respect to a configuration different from that of the electrode module (100) according to one embodiment of the present invention.

[0057] Fig. 4 is a schematic diagram showing an oral grounding electrode device according to one embodiment of the present invention, Fig. 5 is a schematic diagram showing a state of stimulating oral skin through an oral grounding electrode device according to one embodiment of the present invention, and Fig. 6 is a schematic diagram showing a handpiece of an oral grounding electrode device according to one embodiment of the present invention. Fig. 7 is a schematic diagram showing an external electrode of a handpiece of an oral grounding electrode device according to one embodiment of the present invention.

[0058] As illustrated in FIGS. 4 to 7, an oral grounding electrode device according to one embodiment of the present invention may include an external electrode (200), an electrode module (100), a power module (300), and an impedance measurement part (400).

[0059] The external electrode (200) can be brought into contact with the outer surfaces of the cheeks on both sides of the oral cavity and apply current to the outer surfaces of the cheeks on both sides of the oral cavity. This external electrode (200) can be installed in the handpiece (500).

[0060] For example, the external electrode (200) may be non-invasive, and may include multiple ball electrodes (200b). These multiple ball electrodes (200b) may be rolled on the skin surface. Additionally, the power electrode unit may include a patterned flat electrode (see FIG. 7a).

[0061] For example, the external electrode (200) may be an invasive type. This invasive type may include a plurality of needle electrodes (200a). The plurality of needle electrodes (200a) may be installed vertically movably within a first housing (511), which will be described later. Here, a plurality of through holes (511c) may be formed on the lower surface of the first housing (511), through which the plurality of needle electrodes (200a) protrude or are inserted. (See FIGS. 6 and 7b)

[0062] The handpiece (500) can serve as a handle held by the practitioner's hand or a robotic arm. For example, when the handpiece (500) is held by the practitioner's hand or a robotic arm, the external electrodes (200) installed on one side of the handpiece (500) can contact the outer surfaces of the cheeks on both sides of the oral cavity to apply current.

[0063] The handpiece (500) may include a housing (510), a driving part (520), and a support part (530).

[0064] The housing (510) is the basic body of the handpiece (500), and an external electrode (200), a driving part (520), and a support part (530) can be stored in the housing (510).

[0065] The housing (510) may include a first housing (511) and a second housing (512). For example, the first housing (511) may be positioned below the second housing (512). In addition, the first housing (511) and the second housing (512) may be screw-coupled. In addition, at least one external electrode (200) may be provided on the lower surface of the second housing (512). For example, the housing (510) is preferably composed of the first housing (511) and the second housing (512), but may also be composed in an integrated form.

[0066] A first chamber (511a) and a second chamber (511b) may be formed inside the first housing (511). Here, the first chamber (511a) may be positioned below the second chamber (511b). In addition, the upper surface of the second chamber (511b) may be open, and the opening of the upper surface of the second chamber (511b) may be covered by the second housing (512). In addition, a plurality of through holes (511c) through which a plurality of needle electrodes (200a) protrude or are inserted may be formed on the lower surface of the first housing (511).

[0067] An external electrode (200) may be placed in the first chamber (511a), and a support unit may be placed in the second chamber (511b). Here, one side of the external electrode (200) may be placed in the second chamber (511b) and elastically supported by the support unit.

[0068] For example, various fluids can be injected into the first chamber (511a) by the first pump (540). For example, the fluids can be coolants or drugs.

[0069] The driving part (520) can be placed inside the second housing (512). The driving part (520) can be connected to the external electrode (200) through the support part (530).

[0070] The driving part (520) can move the external electrode (200) in a direction in which it protrudes from the handpiece (500) or is inserted into the handpiece (500). As an example, a step motor or an actuator can be used as the driving part (520).

[0071] The support part (530) is placed in the second chamber (511b) and can connect the driving part (520) and the external electrode (200). This support part (530) can include an elastic member (531) and a support pad (532).

[0072] The elastic member (531) may be a compression spring. One side of the elastic member (531) may be in contact with the support pad (532), and the other side of the elastic member may be in contact with the bottom surface of the second chamber (511b). Accordingly, the elastic member may elastically support the support pad (532).

[0073] The support pad (532) can be connected to an external electrode (200).

[0074] The electrode module (100) can be placed between the inner surface of the cheeks on both sides of the oral cavity and the teeth, and as described above, a detailed description thereof will be omitted.

[0075] The power module (300) may serve to supply power to the electrode module (100) and the external electrode (200). The power module (300) may control the intensity, wavelength, direction, etc. of the current applied to the external electrode (200). In addition, the power module (300) may be provided with a display panel (310). For example, the intensity, wavelength, direction, and biometric information of the deep oral skin of the current applied to the external electrode (200) may be displayed on the display panel (310).

[0076] The power module (300) may be provided with a control panel (320). For example, the control panel (320) may be provided in the form of a touch screen. As another example, the control panel (320) may provide the practitioner with the function of controlling the intensity of the current applied to the skin.

[0077] The impedance measurement part (400) is electrically connected to the first ground electrode (10) and the second ground electrode (20), and can measure the impedance of the first ground electrode (10) and the second ground electrode (20).

[0078] For example, when there are multiple first ground electrodes (10) and multiple second ground electrodes (20), the impedance measurement part (400) can measure the impedance of each of the multiple first ground electrodes (10) and the multiple second ground electrodes (20).

[0079] For example, when the first ground electrode (10) and the second ground electrode (20) are each in close contact with the inner surface of the cheeks on both sides of the oral cavity, the impedance values ​​of the first ground electrode (10) and the second ground electrode (20) increase. Therefore, when the first ground electrode (10) and the second ground electrode (20) are each in close contact with the inner surface of the cheeks on both sides of the oral cavity, the impedance values ​​of the first ground electrode (10) and the second ground electrode (20) measured by the impedance measuring part (400) may be greater than a preset value. As another example, when the first ground electrode (10) and the second ground electrode (20) are each spaced apart from the inner surface of the cheeks on both sides of the oral cavity, the impedance values ​​of the first ground electrode (10) and the second ground electrode (20) may be less than a preset value. In this way, when the first ground electrode (10) and the second ground electrode (20) are spaced apart from the inner surface of the left side of the oral cavity, the stimulation effect of the oral skin due to the current application can be reduced. Therefore, it is desirable to notify the operator when at least one of the plurality of measurement values ​​measured from the plurality of first ground electrodes (10) and the plurality of second ground electrodes (20) falls outside a preset range.

[0080] To this end, the impedance measurement part (400) may generate an alarm if at least one of the plurality of measured values ​​measured from the plurality of first ground electrodes (10) and the plurality of second ground electrodes (20) falls outside a preset range. For example, the alarm may include an alarm sound, vibration, and a warning window displayed on the display. As another example, the setting range may be 50Ω to 600Ω.

[0081] FIG. 8 is a schematic diagram showing an example of a first elastic member, a second elastic member, and a fluid injection part of an oral grounding electrode device according to an embodiment of the present invention, FIG. 9 is a schematic diagram showing another example of a first elastic member, a second elastic part, and a fluid injection part of an oral grounding electrode device according to an embodiment of the present invention, and FIGS. 10 and 11 are schematic diagrams showing an operation process of a first elastic member, a second elastic member, and a fluid injection part of an electrode module of an oral grounding electrode device according to an embodiment of the present invention.

[0082] As illustrated in FIGS. 8 and 9, the oral grounding electrode device according to one embodiment of the present invention may further include a first elastic member (40), a second elastic member (50), and a fluid injection part (600).

[0083] The first elastic member (40) is arranged on the inner surface of the first ground electrode (10) facing the teeth, and can press the first ground electrode (10) against the inner surface of the left cheek of the oral cavity when expanded. For example, the first elastic member (40) can be coupled to the inner surface of the first ground electrode (10) facing the teeth. As another example, the first elastic member (40) can be interposed between the inner surface of the first ground electrode (10) facing the teeth and the teeth. As another example, the first elastic member (40) can be expanded by fluid injection of the fluid injection part (600) described below.

[0084] The second elastic member (50) is arranged on the inner surface of the second ground electrode (20) facing the teeth, and can press the second ground electrode (20) against the inner surface of the right cheek of the oral cavity when expanded. For example, the second elastic member (50) can be coupled to the inner surface of the second ground electrode (20) facing the teeth. In another example, the second elastic member (50) can be interposed between the inner surface of the second ground electrode (20) facing the teeth and the teeth. In another example, the second elastic member (50) can be expanded by fluid injection of the fluid injection part (600) described later.

[0085] For example, the first elastic member (40) and the second elastic member (50) may be provided with an injection port through which air can be injected or discharged by the user. Accordingly, the first elastic member (40) and the second elastic member (50) can be adjusted to an appropriate size between the inner surface of the oral cavity and the teeth by injecting or discharging air.

[0086] For example, an elastic membrane may be provided at the injection port. The elastic membrane may function to open and close the injection port. One side of the elastic membrane may be connected to one side of the injection port, and the other side of the elastic membrane may be in close contact with the other side of the injection port. Accordingly, when air is injected or discharged into the injection port, the space between the other side of the elastic membrane and the other side of the injection port may be opened, allowing air to pass through, and then the space between the other side of the elastic membrane and the other side of the injection port may be closed by elastic restoration of the elastic membrane.

[0087] The fluid injection part (600) can inflate at least one of the first elastic member (40) and the second elastic member (50) by injecting fluid therein. For example, the fluid may be a gas or a liquid. Here, the gas may include air, and the liquid may include a driving fluid.

[0088] The fluid injection part (600) may include a first injection pipe (610), a second injection pipe (620), a first valve (630), a second valve (640), and a second pump (650). Here, the first injection pipe (610) may connect the first expansion member (40) and the second pump (650). In addition, the second injection pipe (620) may connect the second expansion member (50) and the second pump (650). In addition, the first valve (630) may open and close the first injection pipe (610). In addition, the second valve (640) may open and close the second injection pipe (620). The second pump (650) may inject fluid into at least one of the first expansion member (40) and the second expansion member (50) to expand them. Additionally, the second pump (650) can contract the fluid by sucking it from at least one of the first elastic member (40) and the second elastic member (50).

[0089] For example, the first pump (540) and the second pump (650) may be configured as a single pump.

[0090] For example, the fluid injection part (600) can be installed separately. (See Fig. 8)

[0091] As another example, the fluid injection part (600) can be installed integrally with the power module (300). (See FIG. 9)

[0092] Hereinafter, the operation process of the first elastic member (40), the second elastic member (50), and the fluid injection part (600) will be described.

[0093] First, a first ground electrode (10) is placed between the inner surface of the left cheek of the oral cavity and the teeth, and a first elastic member (40) is placed on the opposite surface of the first ground electrode (10) facing the teeth. Although not shown in the drawing, similarly, a second ground electrode (20) is placed between the inner surface of the right cheek of the oral cavity and the teeth, and a second elastic member (50) is placed on the opposite surface of the second ground electrode (20) facing the teeth. (See Fig. 10)

[0094] Next, the fluid injection part (600) injects air into the first elastic member (40) and the second elastic member (50). As a result, as the first ground electrode (10) is pressed against the inner surface of the left cheek of the oral cavity due to the expansion of the first elastic member (40), the first ground electrode (10) is brought into close contact with the inner surface of the left cheek of the oral cavity, and as the second ground electrode (20) is pressed against the inner surface of the right cheek of the oral cavity due to the expansion of the second elastic member (50), the second ground electrode (20) can be brought into close contact with the inner surface of the right cheek of the oral cavity. (See Fig. 11)

[0095] According to the present invention, the electrode module according to one embodiment of the present invention and the skin stimulation device including the same have the effect of improving the stimulation effect of the oral skin by applying current by utilizing the oral skin as a passage through which the current passes.

[0096] While the embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will appreciate that the present invention can be implemented in other specific forms without altering the technical concept or essential features thereof.
