Description

Helmet-type magnetic stimulation device

[0001] The present invention relates to a helmet-type magnetic stimulation device, and more specifically, to a helmet-type magnetic stimulation device that performs non-invasive treatment by applying a magnetic field to the scalp or transcranial region of the human body.

[0002] Transcranial magnetic stimulation (hereinafter referred to as 'TMS') is a brain stimulation technique that activates or inhibits nerve cells in specific areas of the brain using local magnetic field waves induced on the surface of the head outside the body. The principle of TMS is to generate a magnetic field of strength of several Tesla by applying a strong electric current to an electromagnetic coil. It is a method of stimulating the brain by transmitting the fluctuating energy of these magnetic field waves to the brain, thereby inducing depolarization in nerve cells within a range of several centimeters below the coil.

[0003] TMS is a representative non-invasive brain stimulation technique, and its therapeutic applications are being actively researched for conditions such as depression, insomnia, obsessive-compulsive disorder, movement disorders, dementia, and brain dysfunction that do not respond well to drug therapy or psychotherapy. Typically, the recommended treatment time for TMS is about 20 minutes, once a day, five days a week, requiring high-frequency treatment. For example, when magnetic stimulation therapy of about 20 to 50 minutes per day is repeatedly applied over several days to central nervous system diseases such as stroke or spinal cord injury, effects of neuroplasticity, neuroregeneration, and functional recovery have been reported.

[0004] However, since existing TMS treatment devices are not portable, it is difficult to meet such treatment cycles given the conditions of the domestic medical market. Therefore, there is a need to introduce miniaturized TMS treatment devices that can be easily used at home, and accordingly, portable or home-use devices are currently being developed.

[0005] Although several portable TMS treatment devices are being developed, components such as coils and cases are heavy, which can place a strain on the neck or shoulders when worn for extended periods. This weight issue poses a significant inconvenience, particularly for the elderly or physically frail patients. Additionally, the inability to effectively dissipate heat generated by the coils can lead to overheating problems. These issues of weight and heat generation make continuous use of the device difficult and hinder the full benefits of stimulation therapy during long treatment sessions.

[0006] In particular, since these devices are worn directly on the user's head, comfort and lightweight design are essential factors for prolonged use.

[0007] Conventional helmet-type magnetic stimulation devices for transcranial stimulation had the problem of causing discomfort to users when worn due to the heavy weight of components such as the case. Additionally, the cooling systems applied to existing helmet-type magnetic stimulation devices had the problem of failing to efficiently dissipate heat around the coils because the internal air circulation of the device was not smooth.

[0008] The present invention has been devised to resolve the aforementioned conventional problems, and aims to solve the issues of discomfort during wear and heat generation that occur during prolonged use through a lightweight structure and an improved cooling system.

[0009] In addition, the present invention provides a structure and material for a lightweight helmet-type magnetic stimulation device, which can reduce the burden on the user's neck and shoulders compared to conventional devices, thereby improving the continuity of treatment for the elderly or users with weak bodies.

[0010] Furthermore, the present invention aims to present a material technology for a helmet-type magnetic stimulation device capable of simultaneously achieving lightweighting and durability.

[0011] The helmet-type magnetic stimulation device of the present invention for achieving the above-mentioned purpose is a helmet-type magnetic stimulation device that provides non-invasive treatment by applying a magnetic field to intracranial nerve cells or scalp cells, and further comprises a helmet-shaped case part, a lower case part disposed at a predetermined distance from the upper part of the skull, and an upper case part coupled to the upper part of the lower case part to form an internal space, and further comprises a magnetic generating coil installed in the internal space to generate a magnetic field; a coil cover member covering at least a part of the magnetic generating coil; and a cooling part that generates an air flow in the internal space to cool the magnetic generating coil; wherein the lower case part and the upper case part each include an opening, and the lower case part and the upper case part can be fastened together to form a single opening.

[0012] In addition, in the helmet-type magnetic stimulation device of the present invention, the coil cover member may be formed of a foamed plastic material which is a high-strength, lightweight material.

[0013] In addition, the lower case portion of the helmet-type magnetic stimulation device of the present invention may be formed of a foamed plastic material which is a high-strength, lightweight material.

[0014] In addition, the helmet-type magnetic stimulation device of the present invention may have a foamed plastic material with a specific gravity of 0.02 to 0.2.

[0015] In addition, the foamed plastic material of the helmet-type magnetic stimulation device of the present invention may be a material having biocompatibility and flame retardancy.

[0016] In addition, the helmet-type magnetic stimulation device of the present invention may have the foamed plastic material be expanded polypropylene (EPP).

[0017] In addition, the helmet-type magnetic stimulation device of the present invention comprises, in the cooling unit, a blower that generates airflow in the internal space, and a first cooling hole and a second cooling hole that are open to introduce air into the internal space or discharge air from the internal space, wherein the blower allows air for cooling the magnetic generating coil to be introduced from the first cooling hole and discharged through the second cooling hole.

[0018] In addition, the helmet-type magnetic stimulation device of the present invention has a first cooling hole formed adjacent to the magnetic generating coil, air flowing into the first cooling hole flows along one side of the magnetic generating coil, and a second cooling hole is formed at a position spaced apart from the magnetic generating coil by a predetermined distance, and air that has cooled the magnetic generating coil can be discharged to the outside through the second cooling hole.

[0019] In addition, the helmet-type magnetic stimulation device of the present invention further includes a coil fixing part installed in the lower case part and providing a space for the magnetic generating coil to be seated thereon; and the first cooling hole may be formed in the coil fixing part.

[0020] In addition, the helmet-type magnetic stimulation device of the present invention may have the second cooling hole formed in the lower case portion or the upper case portion on the side of the opening, so that air that has cooled the magnetic generating coil may be discharged through the opening.

[0021] In addition, the helmet-type magnetic stimulation device of the present invention may include, in the coil fixing part, a first support part that supports the outer circumference of the magnetic generating coil and a second support part that supports the inner circumference of the magnetic generating coil.

[0022] In addition, the coil cover member of the helmet-type magnetic stimulation device of the present invention can guide the circulation of air so that air introduced into the first cooling hole is directed toward the second cooling hole.

[0023] In addition, the helmet-type magnetic stimulation device of the present invention may include, in the coil cover member, a first through hole that allows air introduced into the first cooling hole to pass through the magnetic generating coil, and a second through hole that allows air passing through the first through hole to be discharged toward the second cooling hole.

[0024] In addition, the helmet-type magnetic stimulation device of the present invention includes a coil cover member that provides an air circulation path between the first through hole and the second through hole, and the path may be defined by a perimeter portion that surrounds the first through hole and the second through hole and protrudes to a predetermined height.

[0025] In addition, the helmet-type magnetic stimulation device of the present invention has a first through hole formed adjacent to the magnetic generating coil, and air flowing along the other side of the magnetic generating coil passes through the first through hole, and a second through hole is formed at a position spaced apart from the magnetic generating coil by a predetermined distance, and air passing through the second through hole can be discharged to the outside through the second cooling hole via the blower.

[0026] As described above, the present invention is a helmet-type magnetic stimulation device equipped with a lightweight structure and an improved cooling system, which solves the wearing discomfort and heat generation problems of existing devices, thereby enabling users to receive treatment more conveniently and effectively.

[0027] This invention minimizes the burden on the user's neck and shoulders by reducing the weight of the device through lightweight materials and an optimized structural design. As a result, prolonged wear becomes possible, and the user experience is improved by reducing fatigue during treatment.

[0028] By applying a significant foamed plastic material, the present invention can significantly improve user convenience and safety by simultaneously realizing lightweighting of the helmet-type magnetic stimulation device, as well as wearability, shock absorption performance, durability, and eco-friendliness.

[0029] The present invention rapidly dissipates heat generated in the coil through a structured cooling system and an optimized air circulation design. This enables continuous use for extended periods without overheating issues and prevents degradation of device performance during treatment, thereby maximizing the therapeutic effect.

These terms are used merely to distinguish one component from another. Therefore, it goes without saying that the first component mentioned below may also be the second component within the technical scope of the present invention.

[0040] In the following embodiments, terms such as "include" or "have" mean that the features or components described in the specification are present, and do not preclude the possibility that one or more other features or components may be added.

[0041] In the drawings, the size of components may be exaggerated or reduced for convenience of explanation. For example, the size and shape of each component shown in the drawings are depicted arbitrarily for convenience of explanation, so the present invention is not necessarily limited to what is illustrated.

[0042] Throughout the specification, the same reference numerals refer to the same components.

[0043] The features of each of the various embodiments of the present invention may be combined or combined with one another, either partially or wholly, and as will be fully understood by those skilled in the art, various technical interlocking and operation are possible, and each embodiment may be implemented independently of one another or together in an interlocking relationship.

[0044] Hereinafter, the helmet-type magnetic stimulation device (100) of the present invention will be described in detail with reference to the attached drawings.

[0045] FIG. 1 is a perspective view illustrating a helmet-type magnetic stimulation device (100) according to one embodiment of the present invention, FIG. 2 and FIG. 3 are exploded perspective views of a helmet-type magnetic stimulation device (100) according to one embodiment of the present invention, and FIG. 4 is a drawing illustrating a helmet-type magnetic stimulation device (100) according to one embodiment of the present invention viewed from the bottom.

[0046] The helmet-type magnetic stimulation device (100) of the present invention provides non-invasive treatment by applying a magnetic field to intracranial nerve cells or scalp cells. As shown in FIGS. 1 to 4, the helmet-type magnetic stimulation device (100) according to an embodiment of the present invention includes a lower case part (10), a coil fixing part (20), a magnetic generating coil (30), a cooling part (40), and a coil cover member (50).

[0047] The case part (10) is a helmet-shaped case member mounted on two upper parts of the human body, and includes a lower case part (11) positioned at a predetermined distance from the upper part of the skull, and an upper case part (12) coupled to the upper part of the lower case part (11) to form an internal space (13).

[0048] The lower case part (11) and the upper case part (12) are formed convexly upward so as to contact the head of the human body and can be mounted at a predetermined distance from the scalp of the human body. The lower case part (11) and the upper case part (12) form an internal space (13) in which a magnetic generating coil (30) is installed between them, and a cooling space through the cooling part (40).

[0049] The case portion (10) includes an opening (14). The opening (14) is a hole formed near the top of the user's head. The lower case portion (11) and the upper case portion (12) each include an opening (14), and the lower case portion (11) and the upper case portion (12) can be fastened together to form a single opening (14).

[0050] The opening (14) provides a path for the cooling air flow described later to be discharged. The helmet-type magnetic stimulation device (100) of the present invention can effectively discharge heat generated in the coil by optimizing the path for internal air circulation. In addition, the opening (14) induces the effect of removing or deleting a part of the frame of the case part (10), thereby promoting the lightweighting of the helmet-type magnetic stimulation device (100). By reducing the weight by the amount of the opening (14), the burden applied to the user's neck and shoulders can be reduced. In this way, the present invention can solve the heat generation problem and improve convenience through a cooling air circulation system including the opening (14) and a lightweight design in the helmet-type magnetic stimulation device (100).

[0051] The coil fixing part (20) is a member that supports or fixes the magnetic generating coil (30) and is formed on the lower case part (11) as shown in FIG. 3. The coil fixing part (20) may be formed integrally with the lower case part (11), or it may be formed as a separate member and fixed on the lower case part (11).

[0052] FIG. 5 is a drawing specifically illustrating the lower case part (11) and the coil fixing part (20) of a helmet-type magnetic stimulation device (100) according to one embodiment of the present invention.

[0053] The coil fixing part (20) includes a first support part (21) formed to support the outer circumference of the magnetic generating coil (30) when the magnetic generating coil (30) is seated on the coil fixing part (20), and a second support part (22) that supports the inner circumference of the magnetic generating coil (30).

[0054] The first support member (21) and the second support member (22) are configured to support the magnetic generating coil (30) so that it can be stably seated at a set position, and serve to prevent the movement of the magnetic generating coil (30) in the lower case member (11). It is preferable that the first support member (21) and the second support member (22) be formed with a height corresponding to the height of the magnetic generating coil (30) or the coil diameter of the magnetic generating coil (30).

[0055] As shown in FIG. 5, the first support member (21) may have a bend formed therein to facilitate the user in inserting or withdrawing the magnetic generating coil (30) into or from the coil fixing member (20).

[0056] Additionally, the coil fixing part (20) may further include a third support part (23) formed between the first support part (21) and the second support part (22) to support the lower surface of the magnetic generating coil (30). The third support part (23) causes the magnetic generating coil (30) to be spaced apart from the lower case part (11) by a predetermined distance. The third support part (23) serves to form a space of a predetermined distance below the magnetic generating coil (30) so that a fluid for cooling the magnetic generating coil (30) can flow in or out from the first cooling hole (42) described later.

[0057] This third support member (23) may be a plurality of radial rib members connecting the annular first support member (21) and the second support member (22), as shown in FIG. 5. However, the third support member (23) is not limited to this illustrated form and may have a shape different from the illustrated form as long as it is capable of supporting the magnetic generating coil (30) to be seated.

[0058] The magnetic generating coil (30) is a coil wound to have a predetermined diameter and is a member that generates a magnetic field, which is seated on the coil fixing part (20). The output of the magnetic field generated from the magnetic generating coil (30) can be adjusted for the treatment of various indications such as depression, autism, dementia, insomnia, and hair loss.

[0059] In one embodiment of the present invention, the magnetic generating coil (30) in the helmet-type magnetic stimulation device is exemplified as having an overall elliptical shape, but is not limited thereto. The magnetic generating coil (30) may be a coil wound to have various shapes such as a circular, elliptical, figure-eight, disc, polygonal, or butterfly shape, and the magnetic generating coil (30) should be understood as encompassing the general shape of a conventional TMS coil.

[0060] The cooling unit (40) cools the magnetic generating coil (30) by generating a flow of fluid, i.e., air, in the internal space of the case unit. Referring to FIG. 5, the cooling unit (40) includes a blower (41) that blows air to the magnetic generating coil (30), a first cooling hole (42), a second cooling hole (43), and a fluid guide unit (44).

[0061] A blower (41) is installed in the internal space (13) of the case part (10) and generates airflow in the internal space (13). The blower (41) is seated in the lower case part (11) and generates airflow to cool the magnetic generating coil (30). As shown in FIG. 5, the lower case part (11) provides a space in which the blower (41) is seated.

[0062] The blower (41) generates an airflow that cools the magnetic generating coil (30) by introducing air into the internal space (13) of the case part (10) or by discharging air from the internal space (13). The blower (41) is a device that blows air into the internal space (13) to cool the heat generated from the magnetic field generating part (30), and includes cooling means such as a fan or a blower.

[0063] The helmet-type magnetic stimulation device (100) of the present invention may include a plurality of blowers (41). The blowers (41) may be provided in the left and right regions of the lower case part (11), respectively, based on the magnetic generating coil (30).

[0064] The cooling unit (40) includes a plurality of cooling holes that introduce air into the internal space (13) or discharge air from the internal space (13). The cooling unit (40) includes a first cooling hole (42) and a second cooling hole (43) that introduce air into the internal space (13) or discharge air. The blower (41) allows air for cooling the magnetic generating coil (30) to be introduced from the first cooling hole (42) and discharged through the second cooling hole (43).

[0065] The first cooling hole (42) is formed adjacent to the magnetic generating coil (30), and the second cooling hole (43) is formed at a position spaced apart from the magnetic generating coil by a predetermined distance. The blower (41) allows air introduced from the vicinity of the magnetic generating coil (30) through the first cooling hole (42) to pass through the magnetic generating coil (30) and be discharged to the second cooling hole (43).

[0066] The air introduced into the first cooling hole (42) flows along one side of the magnetic generating coil (30). The introduced air is outside air and has a lower temperature than the surrounding air of the magnetic generating coil (30). One side (bottom) of the magnetic generating coil (30) is the part that is in close contact with the human body and is the part where heat generation is maximized. By allowing the air introduced from the first cooling hole (42) to first come into contact with the bottom of the magnetic generating coil (30), the cooling efficiency can be improved.

[0067] It is preferable that the first cooling hole (42) be formed in the coil fixing part (20), which provides a space for the magnetic generating coil (30) to be seated. As shown in FIG. 5, the first cooling hole (42) may be formed inside the second support part (22). Air introduced through the first cooling hole (42) may be guided through the second support part (22) toward the bottom surface of the magnetic generating coil (30). The air flow path of the cooling air will be described in detail later with reference to FIGS. 7 to 9.

[0068] The second cooling hole (43) is formed at a position spaced apart from the magnetic generating coil (30) by a predetermined distance, and the air that cools the magnetic generating coil (30) is finally discharged to the outside through the second cooling hole (43).

[0069] A second cooling hole (43) is formed near an opening (14) formed in the case part (10). Air that has cooled the magnetic generating coil (30) through the second cooling hole (43) is discharged through the opening (14). Referring to FIGS. 3 and 5, the lower case part (11) or the upper case part (12) forming the opening (14) includes a groove or a bent shape near the opening (14), and a second cooling hole (43), which is a hole through which air is discharged, can be formed as the lower case part (11) and the upper case part (12) are fastened together.

[0070] Multiple second cooling holes (43) may be formed. Since the second cooling holes (43) are configured to discharge air flowing out from the blower (41) to the outside, it is preferable that the shape and size of the second cooling holes (43) be adjusted according to the location and arrangement of the blower (41).

[0071] Additionally, the cooling section (40) may further include a fluid guide section (44) that guides fluid flowing in or out from the first cooling hole (42). The fluid guide section (43) may be a rib member that extends near the first cooling hole (42) to guide the fluid. The fluid guide section (44) defines an area through which air flowing in from the first cooling hole (42) or air discharged into the first cooling hole (42) mainly passes.

[0072] As shown in FIG. 5, the fluid guide member (44) may be a rib member installed in the coil fixing member (20). The fluid guide member (44) may be formed in a shape similar to the third support member (23) that supports the lower surface of the magnetic generating coil (30). The fluid guide member (44) may be a plurality of radial rib members formed between the annular first support member (21) and the second support member (22), and may be arranged alternately with the third support member (23). However, the fluid guide member (43) is not limited to this illustrated shape, and it is obvious that it may have a shape different from the illustrated shape as long as it allows the fluid introduced from the first cooling hole (42) to spread uniformly around the magnetic generating coil (30).

[0073] A coil cover member (50) is included in the path where air flowing into the first cooling hole (42) heads toward the second cooling hole (43). FIG. 6 is a drawing specifically illustrating the coil cover member (50) of a helmet-type magnetic stimulation device (100) according to an embodiment of the present invention.

[0074] A helmet-type magnetic stimulation device (100) according to an embodiment of the present invention may include a coil cover member (50). The coil cover member (50) serves to guide the circulation of air so that air introduced into the first cooling hole (42) is directed toward the second cooling hole (43). The coil cover member (50) is a member that covers at least a portion of the magnetic generating coil (30). Additionally, the coil cover member (50) is formed in a structure that partially covers the upper surface of the magnetic generating coil (30) when the magnetic generating coil (30) is seated on the coil fixing part (20), thereby enabling the magnetic generating coil (30) to be stably supported in the helmet-type magnetic stimulation device (100) of the present invention.

[0075] Referring to FIG. 6, the coil cover member (50) includes a first through hole (51), a second through hole (52), a passage (53) connecting the first through hole (51) and the second through hole (52), and a perimeter (54) defining the passage (53).

[0076] The first through hole (51) allows air flowing into the first cooling hole (42) to pass through the magnetic generating coil (30). In other words, the first through hole (51) provides a path for air flowing into the first cooling hole (42) to pass through the magnetic generating coil (30) and move toward the second cooling hole (43). The first through hole (51) is formed adjacent to the magnetic generating coil (30) so that air flowing along the other side of the magnetic generating coil (30) can pass through the first through hole (51). As shown in FIG. 6, the first through hole (51) may be included in multiple locations covering the upper surface of the coil and corresponding to the shape of the coil.

[0077] The second through hole (52) provides a path for air passing through the first through hole (51) to be discharged toward the second cooling hole (43). The second through hole (52) is a hole that guides air to the blower (41), and it is preferable that the second through hole (52) be formed to correspond to the location where the blower (41) is installed. Air passing through the second through hole (52) is guided to the second cooling hole (43) via the blower (41). Air passing through the second through hole (52) can be discharged to the outside through the second cooling hole via the blower (41). The second through hole (52) is formed at a location spaced apart from the magnetic generating coil (30) by a predetermined distance.

[0078] Additionally, the coil cover member (50) includes a passage (53) that provides an air circulation path between the first through hole (51) and the second through hole (52). The passage (53) may be defined by a perimeter (54) formed to protrude to a predetermined height while encircling the first through hole (51) and the second through hole (52). The passage (53) serves to guide the air introduced through the first through hole (51) toward the blower (41) without leakage.

[0079] Additionally, the coil cover member (50) includes a protrusion (55) that contacts the magnetic generating coil (30) on the surface facing the magnetic generating coil (30) when installed. The protrusion (55) serves to block the flow of air so that air introduced toward the magnetic generating coil (30) can flow along an intended path. The protrusion (55) will be described in detail later with reference to FIG. 7.

[0080] The coil cover member (50) forms an optimal cooling path that allows air introduced from the first cooling hole (42) to cool the magnetic generating coil (30) in an efficient path and be discharged to the outside through the blower (41). The helmet-type magnetic stimulation device (100) of the present invention can improve the cooling efficiency of the device through the optimized design of the coil cover member (50).

[0081] FIGS. 7 to 9 are drawings illustrating an optimized air circulation path of a helmet-type magnetic stimulation device (100) according to one embodiment of the present invention.

[0082] First, the path through which air introduced into the helmet-type magnetic stimulation device (100) flows out to the outside is described. Referring to FIG. 7, external cooling air is introduced through the first cooling hole (42). The first cooling hole (43) is formed in the coil fixing part (20) and can be formed near the center of the magnetic generating coil (30). External cooling air is introduced near the center of the magnetic generating coil (30) through the first cooling hole (42). The air introduced through the first cooling hole (42) is guided to the bottom surface of the magnetic generating coil (30) via the second support part (22).

[0083] At this time, the protrusion (55) formed on the coil cover member (50) serves to block the flow of air so that air introduced from the first cooling hole (42) to the magnetic generating coil (30) can flow along the intended path. The protrusion (55) blocks the air introduced from the first cooling hole (42) from heading toward the upper surface of the magnetic generating coil (30). The protrusion (55) is formed in a shape that contacts the upper surface of the magnetic generating coil (30), and it is preferable that it be formed in an annular shape like the second support member (22). The protrusion (55) may be formed with a diameter slightly larger than that of the second support member (22), and may have a shape in which the second support member (22) is inserted into the space formed by the protrusion (55).

[0084] Air guided to the bottom surface of the magnetic generating coil (30) cools the magnetic generating coil (30) and is then guided to the top surface along the outer circumference of the magnetic generating coil (30). Air guided to the top surface of the magnetic generating coil (30) cools the top surface of the magnetic generating coil (30) and is then discharged through the first through hole (51) of the coil cover member (50).

[0085] Air guided through a plurality of first through holes (51) follows the flow path (53) of the coil cover member (50) to the second through hole (52) as shown in FIG. 8. Air passing through the second through hole (52) is guided to the second plurality of cooling holes (43) via the blower (41) as shown in FIG. 9.

[0086] The helmet-type magnetic stimulation device (100) includes an optimized air circulation path in which incoming air passes sequentially through a first cooling hole (42), the bottom surface of a magnetic generating coil (30), the top surface of a magnetic generating coil (30), a first penetration hole (51) and a second penetration hole (52) of a coil cover member (50), a blower (41), and a second cooling hole (43) before being discharged to the outside. The present invention can rapidly discharge heat generated in the coil through such a structured cooling system and an optimized air circulation design.

[0087] Meanwhile, FIG. 10 is a drawing illustrating various modified structures of the coil fixing part of a helmet-type magnetic stimulation device according to another embodiment of the present invention.

[0088] As described above, the magnetic generating coil (30) may be a coil wound to have various shapes, such as a circle, a figure-eight, or a butterfly shape, in addition to the elliptical shape shown in FIGS. 1 to 9.

[0089] FIG. 10 is a schematic diagram illustrating a first support member (21') and a second support member (22') of a coil fixing part capable of supporting a figure-eight coil when the magnetic generating coil (not shown) is a figure-eight coil. The first support member (21') is a support member that supports the outer circumference of the figure-eight coil, and the second support member (22') is a support member that supports two inner circumferences of the figure-eight coil. It is made clear that such modified forms may also be included within the scope of the present invention.

[0090] Meanwhile, the lower case portion (11) and the coil fixing portion (20) of the helmet-type magnetic stimulation device (100) may be formed from a high-strength, lightweight foamed plastic material. Additionally, the coil cover member (50) of the helmet-type magnetic stimulation device (100) may be formed from a high-strength, lightweight foamed plastic material. It is preferable that the foamed plastic material has a specific gravity of 0.02 to 0.2.

[0091] Specifically, the above-mentioned foamed plastic material may be expanded polypropylene (EPP).

[0092] EPP is a very lightweight material with a density of 15 to 200 kg / m³, which significantly reduces the overall weight of the helmet compared to conventional plastic materials, thereby contributing to reducing fatigue when wearing the magnetic stimulation device (100) for a long time. In addition, EPP has excellent shock absorption performance, so it can protect the user and sensitive parts inside the device from external impacts.

[0093] In addition, EPP is a biocompatible material that can be used in products that come into contact with the human body, and it possesses the characteristics of a material that does not induce toxic reactions, allergies, or inflammatory reactions upon contact with the human body. Since EPP material does not contain heavy metals or chemical components harmful to the human body, it does not cause toxic reactions even when in direct contact with the skin (Non-toxic & Safe), and as a material with a low potential for causing allergies, it can prevent skin inflammation and rashes caused by sweat or moisture (Hypoallergenic). Therefore, this EPP material is suitable for use in the helmet-type magnetic stimulation device (100) of the present invention that comes into direct contact with the human body.

[0094] In addition, EPP is 100% recyclable and has the advantage of having minimal environmental impact during manufacturing and disposal. When EPP material is utilized in the helmet-type magnetic stimulation device (100) of the present invention, it has an excellent effect on improving the durability and weight reduction of the device.

[0095] In addition, the foamed EPP has low density and a large surface area, which gives it flame retardancy that slows down heat conduction during combustion. In particular, adding a halogen-based flame retardant, a phosphorus-based flame retardant, or an inorganic flame retardant to the EPP increases the ignition temperature and slows down the combustion speed. This EPP material can meet the HB and V-0 flame retardant standards required for products such as medical devices, and since the helmet-type magnetic stimulation device (100) of the present invention includes a magnetic generating coil (30) which is a high-temperature heating element, the flame retardant properties of this EPP are particularly required.

[0096] Although embodiments of the present invention have been described above with reference to the attached drawings, those skilled in the art will understand that the present invention may be implemented in other specific forms without changing the technical concept or essential features thereof. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive.
