Description

Technical Field

[0001] This invention relates to the field of magnetic stimulation equipment technology, and more particularly to a combined magnetic therapy chair with automatic switching between dual positions for pelvic floor therapy and sacral nerve therapy. Background Technology

[0002] Currently, when switching from pelvic floor therapy to sacral nerve therapy using existing magnetic therapy cushions, the procedure is cumbersome for doctors. The switching between pelvic floor and sacral nerve therapy cannot be automated; doctors must manually operate the equipment and guide the patient to adjust their position. Therefore, automated combined treatment plans are not possible. This issue limits combined treatment options, complicates the doctor's work, and results in relatively low overall equipment utilization efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a combined magnetic therapy chair with automatic switching between two body positions, so as to solve the problems encountered in the above-mentioned background art.

[0004] To achieve the above objectives, the technical solution of the present invention is as follows:

[0005] A combined magnetic therapy chair with automatic switching between two body positions includes a seat cushion with a backrest, and a frame body connected to the bottom two sides of the seat cushion. The chair is characterized in that: a magnetic therapy coil device is provided on the inner bottom side of the frame body; the magnetic therapy coil device is mounted on the top of the base frame via a bracket; a planar four-bar linkage is installed on each side of the base frame, with the top of each planar four-bar linkage hinged to both sides of the frame body; a first pushing device is installed on the base frame, with the end of the pushing rod of the first pushing device hinged to a connecting rod on one side of the planar four-bar linkage; the base frame drives the planar four-bar linkage to move, thereby causing the seat cushion to flip.

[0006] In the above scheme, the first pushing device is provided, and the end of the pushing rod of the first pushing device is hinged to the middle of the crossbar between the two planar four-bar mechanisms, which is used to push the planar four-bar mechanism to move, thereby driving the seat cushion to flip, so that the user is in a semi-reclining state on the seat cushion, and the user's sacral nerve position is located at the center of the magnetic therapy coil device.

[0007] In the above scheme, when the seat cushion is not flipped over, the user's pelvic floor is located at the center of the magnetic therapy coil device.

[0008] In the above scheme, a second pushing device is installed on one side of the bracket supporting the magnetic therapy coil device, and a leg support is rotatably connected to the end of the seat cushion. The end of the pushing rod of the second pushing device is hinged to the leg support.

[0009] Furthermore, leg grooves are provided on both sides of the upper surface of the leg support.

[0010] In the above scheme, the bottom of the base frame is equipped with feet at all four ends.

[0011] In the above scheme, one side of the connecting rod of the planar four-bar linkage is a folded rod.

[0012] In the above scheme, an inflatable air cushion and a pressure sensor are installed on the seat plate of the seat cushion. The pressure sensor is used to collect the pressure data of the inflatable air cushion.

[0013] Furthermore, the inflatable air cushion has a long strip structure and is made of a flexible membrane.

[0014] Furthermore, the inflatable air cushion has a planar structure and is composed of spaced-apart sub-airbags, including a main positioning airbag located in the middle and auxiliary positioning airbags symmetrically arranged around the main positioning airbag. Each sub-airbag is made of a flexible membrane.

[0015] Compared with existing technologies, the beneficial effects of this invention are as follows: Under normal conditions, this magnetic therapy cushion provides pelvic floor treatment to patients. The automatic switching of positions via a planar four-bar linkage at the bottom of the frame facilitates sacral nerve treatment, making treatment options more diverse. The entire operation is simple when changing the patient's position, reducing the workload of doctors and increasing the utilization rate of the magnetic therapy cushion. Specifically, a pushing device drives the planar four-bar linkage to rotate the cushion. The rotation angle is controlled within 30±5 degrees, allowing the patient to lean back in a seated position. This ensures that the treatment position for the sacral nerve is precisely positioned at the center of the magnetic coil stimulation device, thus providing sacral nerve treatment to the patient.

[0024] To make the technical means, creative features, objectives, and effects of this invention readily understandable, the invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the relevant components of the invention.

[0025] According to the technical solution of the present invention, without changing the essential spirit of the present invention, those skilled in the art can propose various interchangeable structural methods and implementations. Therefore, the following detailed embodiments and accompanying drawings are merely exemplary descriptions of the technical solution of the present invention, and should not be regarded as the entirety of the present invention or as a limitation or restriction of the technical solution of the present invention.

[0026] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0027] Example 1, as Figure 1-6 As shown, a combined magnetic therapy chair with automatic switching between dual positions includes a seat cushion 1 and a base frame 2. The seat cushion 1 is a seat cushion with a backrest. The bottom two sides of the seat cushion 1 are welded and fixedly connected to the frame body 14. The bottom inner side of the frame body 14 is provided with a magnetic therapy coil device 11. The magnetic therapy coil device 11 is installed on the top of the base frame 2 through a bracket. The magnetic therapy coil device 11 is used to treat the patient's pelvic floor and sacral nerves respectively.

[0028] Planar four-bar linkages 21 are installed on both sides of the base frame 2. The top of each planar four-bar linkage 21 is hinged to both sides of the frame body 14. The planar four-bar linkages 21 drive the frame body 14 and the seat cushion 1 to move to a certain angle. A first pushing device 22 is installed on the base frame 2. The end of the pushing rod of the first pushing device 22 is hinged to one side of the connecting rod of the planar four-bar linkage 21. The first pushing device 22 pushes the planar four-bar linkage 21 to move, thereby causing the seat cushion 1 to flip. The first pushing device 22 can be any one of an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0029] Specifically, the first pushing device 22 is provided, with its pushing rod end hinged to the crossbar between the two planar four-bar linkages 21. This allows the pusher to move the planar four-bar linkages 21, thereby causing the seat cushion 1 to flip, positioning the user in a semi-reclined position. By controlling the pushing stroke distance of the first pushing device 22, the planar four-bar linkages 21 deform accordingly, ensuring the user's sacral nerve is precisely positioned at the center of the magnetic therapy coil device 11. Alternatively, two first pushing devices 22 can be used, each pushing the planar four-bar linkages 21 on either side, causing the seat cushion 1 to form a V-shaped structure, lifting the patient's buttocks and placing the sacral nerve at the bottom, facilitating sacral nerve treatment by the magnetic therapy coil device 11 directly below.

[0030] Moreover, when the seat cushion 1 is not flipped over, and the user sits on it, the position of the user's pelvic floor is located at the center of the magnetic therapy coil device 11, which is used to perform magnetic stimulation therapy on the user's pelvic floor nerves.

[0031] In the above scheme, one side of the planar four-bar linkage 21 is a folded bar 24. Generally, the folded bar 24 is set on the link behind the seat cushion 1. This allows the front link to be raised higher, raising the seat cushion 1, so that the patient's entire buttocks can be placed directly below the magnetic therapy coil device 11 during sacral nerve treatment, that is, at the center of the magnetic therapy coil device 11, so as to achieve a good therapeutic effect.

[0032] In the above scheme, feet 23 can be installed at the four ends of the bottom of the base frame 2 to stabilize the entire seat cushion 1 and stabilize the support force of the planar four-bar mechanism 21 during sacral nerve treatment.

[0033] In this embodiment, refer to Figures 1 to 3 When seat cushion 1 is in its normal position, the patient sits on it for pelvic floor therapy. (See also...) Figures 4 to 6 When the planar four-bar linkage 21 is pushed by the first pushing device 22, the seat cushion 1 is in a V-shape. At this time, the rotation angle of the seat cushion 1 is controlled within the range of 30±5 degrees, which is used to treat the sacral nerve of the patient sitting on it.

[0034] In Example 2, based on Example 1, a second pushing device 12 is installed on one side of the support bracket of the magnetic therapy coil device 11. A leg rest 13 is rotatably connected to the end of the seat cushion 1. The pushing rod end of the second pushing device 12 is hinged to the leg rest 13 to lift the leg rest 13, making the patient's legs more comfortable. In implementation, the second pushing device 12 can be any one of an electric push rod, a hydraulic cylinder, or a pneumatic cylinder.

[0035] As a preferred solution, leg grooves 15 are provided on both sides of the upper surface of the leg support 13. When the patient's legs are placed in the leg grooves 15, they are more easily supported and will not swing, resulting in greater comfort. This effectively improves the center of gravity position of the patient's sitting posture, thereby reducing the body's support force, allowing for sustained treatment without significant discomfort, and enhancing the user's treatment experience.

[0036] This magnetic therapy seat cushion is equipped with a magnetic therapy coil device 11 located beneath the seat surface. Initially, the patient sits on the cushion 1 for pelvic floor treatment. While maintaining a relatively stable sitting posture, the first pushing device 22 at the bottom of the base frame 2 adjusts the movement of the cushion 1, allowing the patient to rotate to another body position for sacral nerve treatment. Additionally, the second pushing device 12 drives the leg rest 13, automatically adjusting it to a comfortable angle. The entire process is automatically set and switched, requiring no adjustment or positioning by the doctor.

[0037] This magnetic therapy seat cushion provides pelvic floor treatment in its normal state. Automatic switching is achieved via a planar four-bar linkage 21 at the bottom of the frame 14, facilitating sacral nerve treatment and increasing the versatility of treatment options. The entire operation is simple when changing the patient's position on the seat cushion, reducing the workload for doctors and increasing the utilization rate of the magnetic therapy seat cushion. Specifically, a pushing device drives the planar four-bar linkage 21 to rotate the seat cushion. The rotation angle is controlled within 30±5 degrees, allowing the patient to lean back in a seated position. This ensures that the treatment position for the sacral nerve is precisely positioned at the coil stimulation center of the magnetic therapy coil device 11, providing sacral nerve treatment to the patient.

[0038] Example 3, based on Example 1 or 2, involves installing an inflatable air cushion and a pressure sensor on the seat plate of seat cushion 1. The pressure sensor collects pressure data from the inflatable air cushion. The sensor's acquisition end is connected to the inflatable air cushion via a pipe, allowing for real-time acquisition of pressure distribution on the user's buttocks and legs while using the seat. The inflatable air cushion can detect the user's posture and provide effective magnetic stimulation therapy to the pelvic floor. By configuring a corresponding display module and controller, the pressure data collected by the pressure sensor can be displayed in real time. The display module, which can be a computer or other display device, displays the pressure data. The computer provides a visual display of the posture, allowing the user to check if their posture is at the center of gravity. When the patient's posture is at the center of gravity, the magnetic stimulation module provides effective magnetic stimulation therapy to the pelvic floor.

[0039] When the inflatable air cushion is a long strip structure, it has a raised structure on the shape of the seat plate of the seat cushion 1. It can be laid flat and then glued and fixed to the top outer surface of the seat cushion 1. It is made of a flexible membrane, which is made of polymer material. It does not affect the magnetic field, and the inflatable air cushion is soft and comfortable when in use.

[0040] This method allows for external monitoring during pelvic floor treatment, eliminating the need for invasive procedures, making clinical operation more convenient, and reducing the risk of infection. The thin walls of the air sacs in the inflatable cushion prevent the muscles from being raised away from the stimulation source, thus maintaining stimulation depth. Pressure changes directly reflect the degree of muscle contraction, providing a fast and precise response. The air sacs are also soft and comfortable to use. During treatment, a magnetic field passes through the sofa cushion and acts on the pelvic floor muscles to stimulate them, achieving the therapeutic goal. During treatment, the magnetic field stimulates the pelvic floor muscles, causing muscle contraction. This muscle contraction compresses the inflatable cushion at the perineum. Changes in the pressure of the inflatable cushion are used to assess the response of the pelvic floor muscles to different intensities of stimulation.

[0041] When the inflatable air cushion has a planar structure, it is laid flat and then bonded to the top outer surface of the seat cushion 1. The inflatable air cushion consists of spaced-apart segmented airbags, including a main positioning airbag in the center and auxiliary positioning airbags symmetrically arranged around the main positioning airbag. Each segmented airbag is made of a flexible membrane, such as thermoplastic elastomer membrane, mesh fabric, or leather. The airbag walls are very thin, preventing the airbags from elevating the muscles away from the magnetic stimulation source and affecting the depth of magnetic stimulation treatment.

[0042] This planar inflatable air cushion is used to monitor a person's center of gravity while seated, or to monitor their center of gravity and leg posture. During pelvic floor therapy, the patient needs to open their legs to allow the pelvic floor muscles to receive sufficient magnetic stimulation, maximizing the therapeutic effect, through a magnetic therapy coil device 11 installed inside the seat. When the patient closes their legs, the pressure of the auxiliary positioning airbag increases sharply; the controller processes and outputs data, which is displayed on the display module to remind the patient of their leg movements.
