Description

Technical Field

[0001] This utility model relates to the field of magnetic stimulation therapy device technology, and in particular to a small magnetic stimulation coil structure suitable for treating swallowing disorders. Background Technology

[0002] Nearly half of stroke patients also experience dysphagia. Current traditional treatments such as rehabilitation training and electrical stimulation therapy suffer from problems such as long treatment duration, limited effectiveness, high invasiveness, or unstable results. While magnetic stimulation therapy, as a non-invasive method, has been used in transcranial and peripheral magnetic stimulation, research on its application in treating dysphagia is still insufficient. Existing transcranial and peripheral magnetic stimulation coils are generally too large and heavy, making them unsuitable for treating dysphagia. Summary of the Invention

[0003] To address the problem that existing magnetic stimulation coils are not suitable for treating dysphagia, this invention provides a small magnetic stimulation coil structure suitable for treating dysphagia. The coil structure and shape are designed specifically for the mylohyoid muscle. The coil is small in size and lightweight, allowing it to be placed on the mylohyoid muscle for treatment. It has a small treatment range and high focus, improving the comfort of the treatment experience.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A small magnetic stimulation coil structure suitable for treating dysphagia includes a shell, a coil, and a power cord. The shell is composed of a handle section and a treatment section connected in a "T" shape, which is convenient for the patient to hold and for the coil to be placed. The treatment section has an "8" shaped cross section, and the left and right sides of the treatment section are symmetrically distributed at an angle to fit the treatment site. One edge of the treatment section is concave inward to form an indentation to avoid the Adam's apple position. The indentation is arranged opposite to the handle section. The treatment section contains the coil, which is wound in an "8" shape. The coil on each side of the treatment section is wound in multiple layers from top to bottom and multiple turns from the inside to the outside. Both ends of the coil extend vertically into the handle section. The handle section also contains a power cord, which is electrically connected to both ends of the coil to facilitate the transmission of the current generated by the magnetic stimulation therapy device to the coil.

[0005] Furthermore, the outer shell is a "T"-shaped shell structure made of insulating material, with the treatment section and handle section of the outer shell integrally formed, the treatment section arranged horizontally, and the handle section arranged vertically.

[0006] Furthermore, the outer shell includes an upper shell and a lower shell, which are two-part structures. The upper shell and the lower shell are snapped together for easy assembly and disassembly. The upper shell and the lower shell are connected and combined to form a "T"-shaped hollow shell with a certain cavity inside. Both the upper shell and the lower shell are composed of a handle section and a treatment section.

[0007] Furthermore, positioning sleeves are provided on both sides of the treatment section of the upper shell. The positioning sleeves protrude upwards, and the two positioning sleeves extend into the wound coil respectively, ensuring the coil position is fixed.

[0008] Furthermore, a mounting sleeve is provided between the upper and lower shells, and the mounting sleeve is fixedly fitted onto the handle section ends of the upper and lower shells. This improves the reliability of the installation of the upper and lower shells.

[0009] Furthermore, the included angle between the left and right sides of the treatment section is 150°-180°, the coils are arranged at an included angle of 150°-180° on both sides, the two sides of the treatment section are circular or elliptical, each turn of the coil in the treatment section is wound in a circular or elliptical shape, and the outer diameter of the coil in the treatment section is 50-70mm.

[0010] Furthermore, the coil is an "8" shape wound from one of the following: copper braided wire with an insulating layer, multi-strand copper wire with an insulating layer, single-strand copper wire with an insulating layer, or hollow copper tube with an insulating layer.

[0011] Furthermore, the coil is a hollow copper tube with an insulating layer, and the handle section is also equipped with a first liquid tube and a second liquid tube, which are respectively connected to both ends of the coil to form a cooling circulation pipeline. This facilitates the introduction of circulating liquid for cooling and prevents the coil from overheating.

[0012] The beneficial effects of this utility model through the above technical solution are: This invention features a rational structural design, with the treatment section and coil forming a 150°-180° angle on both sides, which improves coil focusing while conforming to the treatment area. The coil's outer diameter is 50-70mm, resulting in a small overall size that better conforms to the treatment area and reduces overall weight, thus providing better focusing and versatility across age groups, making it more suitable for magnetic stimulation therapy of swallowing disorders. Furthermore, it can also be used for small treatment areas such as the arm and joints. To further improve focusing and reduce the stimulation area, the circular coil and corresponding treatment section can be appropriately deformed into an elliptical shape. Attached Figure Description

[0019] The specific embodiments of this utility model are described in detail below with reference to the accompanying drawings: like Figures 1-5 As shown, a small magnetic stimulation coil structure suitable for treating swallowing disorders includes a housing 1, a coil 2, and a power cord 3. The housing 1 is a "T"-shaped shell structure made of insulating material. Here, the housing 1 is composed of a handle section 4 and a treatment section 5 connected and combined in a "T" shape. The treatment section 5 and the handle section 4 of the housing 1 are integrally formed.

[0020] Treatment segment 5 is arranged horizontally, with a cross-section shaped like an "8". The two sides of treatment segment 5 are circular or elliptical. Treatment segment 5 is symmetrically distributed at an angle to the left and right sides; that is, it is not arranged horizontally but rather in a "V"-shaped bend, with an angle of 150°-180° between the left and right sides. One edge of treatment segment 5 is concave inward to form an indentation 6, which is opposite to handle segment 4. Handle segment 4 is arranged vertically and is tubular. The outer shell 1 has a cavity inside for placing the coil 2. To facilitate the assembly and disassembly of the outer shell 1, the outer shell 1 includes an upper shell 101 and a lower shell 102. The upper shell 101 and the lower shell 102 are basically the same in shape. After the upper shell 101 and the lower shell 102 are connected and combined, they form a "T"-shaped hollow shell. Thus, the outer shell 1 is essentially a two-part structure assembled from the upper shell 101 and the lower shell 102.

[0021] Both the upper shell 101 and the lower shell 102 are composed of a handle section 4 and a treatment section 5. The handle section 4 and the treatment section 5 of the upper shell 101 are injection molded as a single piece, and the handle section 4 and the treatment section 5 of the lower shell 102 are also injection molded as a single piece. As a result, the treatment section 5 of both the upper shell 101 and the lower shell 102 is semi-circular.

[0022] Note that the upper shell 101 and lower shell 102 are snap-fitted together. Specifically, claws 7 are provided on the edges of the handle section 4 and treatment section 5 of the upper shell 101. The claws 7 are L-shaped plates. At the same time, corresponding slots are provided on the edges of the handle section 4 and treatment section 5 of the lower shell 102. The slots are not shown in the figure. The cooperation between the claws 7 and the slots can achieve the snap-fitting and fixing of the upper shell 101 and lower shell 102, preventing them from separating.

[0023] Meanwhile, a mounting sleeve 8 is provided between the upper shell 101 and the lower shell 102. The mounting sleeve 8 is a short, round tube made of insulating material, and it is fixedly fitted onto the ends of the handle segments 4 of the upper shell 101 and the lower shell 102. After the handle segments 4 of the upper shell 101 and the lower shell 102 are snapped into a round tube shape, the mounting sleeve 8 is fitted onto the two handle segments 4. The mounting sleeve 8 is interference-fitted with the handle segments 4, thereby fixing the mounting sleeve 8. This locks the upper shell 101 and the lower shell 102, ensuring the reliability of the assembly of the upper shell 101 and the lower shell 102.

[0024] In this embodiment, the shape of coil 2 is basically the same as that of treatment section 5. Coil 2 is also wound in an "8" shape. Specifically, coil 2 is wound in an "8" shape using one of the following: copper braided wire with an insulating layer, multi-strand copper wire with an insulating layer, single-strand copper wire with an insulating layer, or hollow copper tube with an insulating layer. In short, coil 2 can be wound using different copper materials, and it is formed by winding a single copper material multiple times.

[0025] During installation, coil 2 is placed inside treatment section 5. Coil 2 on each side of treatment section 5 is wound in multiple layers from top to bottom and from the inside to the outside, with both ends of coil 2 extending vertically into handle section 4. Specifically, a copper coil 2 is selected, with a certain length left unwound at both ends; the remaining portion is wound. During winding, first, multiple turns and layers are repeatedly wound on one side of treatment section 5 in a bottom-to-top, inside-to-outside manner. Then, coil 2 is wound into the other side of treatment section 5 in the same manner, with both ends of coil 2 wound into handle section 4.

[0026] Due to the shape limitations of treatment section 5, each turn of coil 2 within treatment section 5 is also wound in a circular or elliptical shape, with an outer diameter of 50-70mm. Due to the angle limitations on both sides of treatment section 5, coil 2 is arranged at an angle of 150°-180° on both sides.

[0027] To ensure the position of coil 2 within treatment section 5, positioning sleeves 9 are provided on both sides of treatment section 5 of upper shell 101. The positioning sleeves 9 protrude upwards, and the two positioning sleeves 9 extend into the wound coil 2, which is equivalent to the coil 2 being wound on the outside of the positioning sleeves 9. The positioning sleeves 9 are used to position the wound coil 2 and prevent the coil 2 from shifting.

[0028] The handle section 4 also contains a power cord 3, which is electrically connected to both ends of the coil 2. That is, after partially stripping the insulation layer from both ends of the coil 2, one end of the power cord 3 is soldered to the coil 2. The other end of the power cord 3 is connected to the magnetic stimulation therapy device. The magnetic stimulation therapy device generates current, which is transmitted to the coil 2 via the power cord 3, thereby generating a magnetic field to achieve the therapeutic purpose of magnetic stimulation.

[0029] It should be noted that in this embodiment, the coil 2 is a hollow copper tube with an insulating layer, allowing fluid to circulate inside for cooling. Specifically, the handle section 4 is also equipped with a first liquid pipe 10 and a second liquid pipe 11, which are connected to both ends of the coil 2 to form a cooling circulation pipeline. In this way, the cooling liquid enters the coil 2 through the first liquid pipe 10, flows around the coil 2, and then flows out of the coil 2 through the second liquid pipe 11, carrying away heat through the circulating liquid.

[0030] The principle of this invention is as follows: The power cord 3 is connected to the magnetic stimulation therapy device. After the device is activated, the current generated is transmitted to the coil 2 via the power cord 3, and the coil 2 generates a magnetic field. The patient holds the outer casing 1 and places the treatment segment 5 on the mylohyoid muscle. This results in a small treatment area and improved focus. The obtuse angle design allows the treatment segment 5 to better fit the chin, enhancing focus; simultaneously, the concave opening 6 avoids the Adam's apple area. The coil 2 has a small overall size, allowing the patient to comfortably lie down or sit for treatment. The fluctuating magnetic field provides repetitive stimulation to specific areas, enhancing the comfort of the treatment experience.

[0031] The embodiments described above are merely preferred embodiments of this utility model and are not intended to limit the scope of implementation of this utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the patent claims of this utility model should be included within the scope of the patent application of this utility model.
