Description

Technical Field

[0001] This invention relates to the field of rehabilitation equipment technology, specifically a multifunctional pelvic floor repair chair. Background Technology

[0002] Currently, in the field of pelvic floor muscle repair, electromagnetic stimulation technology is widely used in pelvic floor repair chairs due to its non-invasive and highly efficient characteristics. Existing pelvic floor repair chairs are typically equipped with an electromagnetic generation system, which mainly consists of a main controller and a focusing coil. The focusing coil is usually placed inside the chair seat, generating a magnetic field to stimulate the contraction of the pelvic floor muscles, thereby achieving the purpose of pelvic floor muscle repair.

[0003] To ensure the focusing coil is aligned with the user's perineum while seated in the pelvic floor repair chair, existing models typically place the focusing coil in the center of the chair seat. However, this placement presents significant drawbacks when used for buttock shaping treatments. Specifically, buttock shaping requires the focusing coil to be aligned with the center of the gluteus maximus muscle belly for optimal results. Because the focusing coil is fixed in the center of the chair seat, users must alternately place both gluteus maximus muscles on the coil during treatment, preventing simultaneous treatment of both muscles. This not only increases operational complexity, prolongs treatment time, and reduces efficiency, but also forces users to constantly adjust their body position, making it difficult to maintain a centered position. This discomfort negatively impacts the user experience and reduces their willingness to cooperate. Therefore, we propose a multifunctional pelvic floor repair chair to effectively address these shortcomings. Summary of the Invention

[0004] The purpose of this invention is to provide a multifunctional pelvic floor repair chair to solve the problems mentioned in the background art.

[0005] This invention is achieved through the following technical solutions:

The positioning cylinder and the base are fixedly connected. The rotating shaft is rotatably connected to the inside of the positioning cylinder, and both ends of the rotating shaft extend out of the outside of the positioning cylinder. The backrest is fixedly connected to the rotating shaft.

[0012] Optionally, the water-locking ring is symmetrically provided with an inlet and an outlet on both sides. The inlet is connected to the outlet of the water tank through a hose, and the outlet is connected to the inlet of the water tank through a hose.

[0013] Optionally, the adjustment mechanism includes a rectangular frame, with displacement blocks slidably provided on both the upper and lower sides of the rectangular frame. Each of the two displacement blocks is provided with a guide rod, and each of the two guide rods has a mounting bracket at its opposite ends. The two mounting brackets are respectively fixedly connected to two water-locking rings.

[0014] Optionally, the upper and lower side walls of the mounting part are provided with guide grooves, and one end of each of the two guide rods is embedded in the two guide grooves. The guide groove is a two-section structure consisting of a horizontal section and an inclined section connected end to end. When the guide rod is located inside the horizontal section, the two water-locking rings are distributed in a concentric circle. When the guide rod is located at the end of the inclined section, the two water-locking rings are distributed symmetrically from left to right.

[0015] Optionally, a displacement frame is fixedly provided at the bottom of the rectangular frame, and the displacement frame and the mounting part slide together along the length direction of the mounting part; a hollow opening is provided on the side of the positioning cylinder near the base, a main shaft is rotatably provided at the hollow opening, a driven gear is fitted on the outside of the main shaft, and a driving gear is fitted on the outside of the rotating shaft, and the driving gear and the driven gear mesh with each other;

[0016] The main shaft is wound with a traction rope. The free end of the traction rope extends into the mounting part and is connected to the displacement frame. A push spring is connected between the displacement frame and the end of the mounting part near the backrest. In the natural state, the push spring is compressed and the traction rope is taut. When the backrest rotates from a vertical position to a horizontal position, the main shaft gradually releases the traction rope.

[0017] Optionally, the guide rod and the displacement block are slidably coupled vertically, and a return spring is sleeved on the outer side of the guide rod. The two ends of the return spring are fixedly connected to the displacement block and the mounting bracket, respectively. In its natural state, the return spring is in a stretched state.

[0023] 1. This invention has two focusing coils, which can be concentrically arranged to treat pelvic floor muscles or symmetrically distributed to treat the gluteus maximus muscles on both sides respectively. Compared with traditional technology, this invention has multiple treatment functions.

[0024] 2. The position of the focusing coil in this invention changes with the adjustment of the backrest angle. When the backrest is in a vertical position, the two focusing coils are concentrically distributed. When the backrest is laid flat, the two focusing coils are symmetrically distributed. Therefore, the user does not need to manually adjust the position of the focusing coils. Instead, it can be adaptively adjusted according to the change of the backrest angle, which greatly facilitates the user's use.

[0025] 3. In this invention, after the backrest is laid flat from a vertical position, the two focusing coils can not only be symmetrically distributed, but also slide forward a certain distance to adapt to changes in the user's hip position, thus helping to improve the accuracy of hip shaping treatment;

[0026] 4. The present invention also includes two water-locking rings, which are located outside the two focusing coils respectively, thereby cooling the focusing coils and preventing them from affecting their working efficiency due to overheating. Attached Figure Description

Detailed Implementation

[0038] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0039] Please see Figure 1 - Figure 10A multifunctional pelvic floor repair chair includes a base 100, a seat 200 on top of the base 100, and a backrest 300 on one side of the seat 200. The base 100 has a hollow structure, and the seat 200 has a sponge interior and a leather exterior to improve comfort and facilitate cleaning. Additionally, a rotating assembly 400 is located on one side of the top of the base 100. The rotating assembly 400 includes a positioning cylinder 401 and a rotating shaft 402. The positioning cylinder 401 is fixedly connected to the base 100, and the rotating shaft 402 is rotatably connected to the inside of the positioning cylinder 401, with both ends of the rotating shaft 402 extending outside the positioning cylinder 401. The backrest 300 is fixedly connected to the rotating shaft 402 for adjusting the backrest angle.

[0040] The rotating assembly 400 also includes an electric drive structure (not shown in the figure), which includes a servo motor and a reducer. The output end of the servo motor is connected to the input end of the reducer, and the output end of the reducer is connected to the rotating shaft 402 via a synchronous belt drive. Therefore, the angle of the backrest 300 can be directly adjusted electronically. Of course, in addition to the electric drive structure described above, other embodiments may also use different drive methods, as long as they can meet the angle adjustment requirements of the backrest 300.

[0041] This embodiment also includes a mounting part 500, an electromagnetic generating mechanism 600, and a water cooling mechanism 700. The mounting part 500 is fixedly mounted on the top of the base 100, and the seat 200 is wrapped around the top outer side of the mounting part 500. The mounting part 500 has an internal hollow structure. Specifically, the mounting part 500 is made of plastic material, such as PE material, with a wall thickness of about 5 mm. It includes a box body 501 and a bottom cover 502. Since the relative magnetic permeability of PE material is extremely low, almost no hysteresis loss is generated when a magnetic field passes through it.

[0042] In addition, the electromagnetic generating mechanism 600 includes a main controller 601 and two focusing coils 602. Both focusing coils 602 are connected to the output terminal of the main controller 601. The main controller 601 is located inside the base 100, and the two focusing coils 602 are located inside the mounting part 500. The main controller 601 is connected to an external power source via a power cord, and the focusing coils 602 are ring-shaped and made of enameled copper wire. When the main controller 601 is powered on, it can generate high-frequency pulse signals (such as 40Hz, 800μs pulse width) to control the magnetic field strength and waveform. The focusing coil 602 is used to generate a high-frequency alternating magnetic field (frequency is usually 20-50Hz) to achieve spatial focusing of electromagnetic energy, so that the energy is concentrated on the target muscle group. When the magnetic field penetrates human tissue, according to the principle of electromagnetic induction, an induced current is induced in the muscle tissue. The induced current stimulates the motor nerve endings, triggering the muscle fiber tonic contraction (the contraction intensity can reach 100%-200% of the voluntary contraction). This "superphysiological limit" contraction can activate the repair and regeneration mechanism of muscle cells.

[0043] Furthermore, the water-cooling mechanism 700 includes a water tank 701 and two water-locking rings 702. The water-locking rings 702 are made of plastic and are respectively wrapped around the two focusing coils 602. Both water-locking rings 702 are connected to the water tank 701 via flexible hoses. Specifically, the water-locking rings 702 have symmetrically arranged inlet ports 703 and outlet ports 704 on both sides. The inlet ports 703 are connected to the outlet of the water tank 701 via flexible hoses, and the outlet ports 704 are connected to the inlet of the water tank 701 via flexible hoses. The water tank 701 is located inside the base 100 and also contains a water pump. The outlet of the water pump is connected to the outlet of the water tank 701. When the water pump is started, the water in the water-locking rings 702 and the water in the water tank 701 can circulate, thereby preventing the water in the water-locking rings 702 from overheating and carrying away the heat generated by the focusing coils 602. It is worth mentioning that the water tank 701 can be connected to an external heat exchanger to cool the water in the water tank 701 and prevent it from overheating.

[0044] It is worth mentioning that the surface of the water-locking ring 702 has two wire-passing holes 705, through which the two ends of the focusing coil 602 pass respectively. The focusing coil 602 is encased in an insulating and waterproof sheath 603. A sealing ring is fitted onto the inner surface of the wire-passing holes 705. The inner ring of this sealing ring fits tightly against the insulating and waterproof sheath 603. The sealing ring is made of flexible silicone and has good sealing properties, preventing water from overflowing from the wire-passing holes 705. The two ends of the focusing coil 602 pass through the two wire-passing holes 705 and penetrate the bottom wall of the mounting part 500 to connect with the main controller 601.

[0045] In addition, armrests 301 are provided on both the left and right sides of the backrest 300, and a control panel 302 is provided on the top surface of one of the armrests 301. The control panel 302 is electrically connected to the main controller 601, and users or staff can control the start / stop and power of the main controller 601 through the control panel 302.

[0046] In some embodiments of this application, an adjustment mechanism 800 is also included. The adjustment mechanism 800 is located inside the mounting portion 500 and connected to two water-locking rings 702. The adjustment mechanism 800 is used to control the movement of the two water-locking rings 702 inside the mounting portion 500. When the backrest 300 is in a vertical position, the two water-locking rings 702 are arranged in a concentric circle. When the backrest 300 is in a horizontal position, the two water-locking rings 702 are arranged symmetrically from left to right. It should be added that the upper surface of the seat 200 has a circular mark. When the backrest 300 is in a vertical position, both focusing coils 602 are located directly below the circular mark, thus facilitating the user to align their perineum with the focusing coils 602.

[0047] The following is a detailed description of the specific structure of the regulating mechanism 800:

[0048] The adjustment mechanism 800 includes a rectangular frame 801. Displacement blocks 802 are slidably mounted on both the upper and lower sides of the rectangular frame 801. The displacement blocks 802 and the rectangular frame 801 slide in a slidable fit along the width direction of the seat 200. Each displacement block 802 is provided with a guide rod 803, and each of the opposing ends of the two guide rods 803 is provided with a mounting bracket 804. The two mounting brackets 804 are respectively fixedly connected to two water-locking rings 702. Specifically, the mounting brackets 804 are cross-shaped, and when the two water-locking rings 702 are concentrically distributed, the two mounting brackets 804 are vertically distributed.

[0049] Furthermore, guide grooves 503 are provided on both the upper and lower side walls inside the mounting part 500. One end of each of the two guide rods 803 is embedded in the two guide grooves 503. The guide groove 503 is a two-section structure consisting of a horizontal section 5031 and an inclined section 5032 connected end to end. The horizontal section 5031 is distributed along the length of the seat 200 and is located on the side closer to the backrest 300. When the guide rod 803 is located inside the horizontal section 5031, the two water-locking rings 702 are distributed in a concentric circle. When the guide rod 803 is located at the end of the inclined section 5032, the two water-locking rings 702 are distributed symmetrically from left to right.

[0050] It should be added that the two inclined sections 5032 located on the upper and lower sides are inclined to the left and right sides respectively. Therefore, when the two guide rods 803 slide along the two inclined sections 5032 and gradually move away from the backrest 300, the two water-locking rings 702 will move away from each other.

[0051] In addition, a displacement frame 805 is fixedly provided at the bottom of the rectangular frame 801. The displacement frame 805 and the mounting part 500 slide together along the length of the mounting part 500. A hollow opening is provided on the side of the positioning cylinder 401 near the base 100. A main shaft 403 is rotatably provided at the hollow opening. A driven gear 405 is fitted on the outside of the main shaft 403. A driving gear 404 is fitted on the outside of the rotating shaft 402. The driving gear 404 and the driven gear 405 mesh with each other. A traction rope 806 is wound around the outside of the main shaft 403. The free end of the traction rope 806 extends into the mounting part 500 and is connected to the displacement frame 805. It should be noted that when the backrest 300 gradually tilts backward from a vertical position, the rotating shaft 402 can drive the main shaft 403 to rotate, and the rotation of the main shaft 403 will release the traction rope 806. Conversely, when the backrest 300 gradually tilts forward from a horizontal position, the rotation of the main shaft 403 will continuously pull the traction rope 806.

[0052] Furthermore, a push spring 807 is connected between the displacement frame 805 and the end of the mounting part 500 near the backrest 300. In its natural state, the push spring 807 is in a compressed state, that is, the push spring 807 always applies a forward thrust to the displacement frame 805, causing the displacement frame 805 to tend to move away from the backrest 300. Therefore, the traction rope 806 is always taut. When the backrest 300 rotates from a vertical position to a horizontal position, the main shaft 403 gradually releases the traction rope 806, and the displacement frame 805 gradually moves away from the backrest 300. Conversely, when the backrest 300 gradually rotates from a horizontal position to a vertical position, the displacement frame 805 will gradually move closer to the backrest 300.

[0053] It is worth mentioning that the displacement frame 805 is a rectangular frame. Both the displacement frame 805 and the rectangular frame 801 are made of plastic and are fixedly connected by bolts. The inner left and right side walls of the mounting part 500 are provided with guide grooves distributed along the length of the seat 200, and the displacement frame 805 slides in cooperation with the guide grooves to improve the stability of the displacement frame 805 when it slides.

[0054] In another embodiment of this application, the guide rod 803 and the displacement block 802 are slidably coupled vertically. A return spring 808 is sleeved on the outer side of the guide rod 803. The two ends of the return spring 808 are fixedly connected to the displacement block 802 and the mounting bracket 804, respectively. In its natural state, the return spring 808 is in a stretched state. Specifically, the displacement block 802 has a through hole for the guide rod 803 to pass through. Under the tension of the return spring 808, the two water-locking rings 702 always tend to move away from each other vertically, so that one end of the guide rod 803 abuts against the guide groove 503.

[0055] Furthermore, both ends of the guide groove 503 are equipped with pads 504. When the guide rod 803 and the pads 504 abut, the two water-locking rings 702 are at the same height; when the guide rod 803 and the inner end of the guide groove 503 abut, the two water-locking rings 702 are staggered vertically. One end of the pad 504 has a bevel as a transition, such as... Figure 7 As shown, this allows the guide rod 803 to move from the guide groove 503 to the pad 504. Specifically, when the guide rod 803 is located at both ends of the guide groove 503, the guide rod 803 is in contact with the pad 504, and the two water-locking rings 702 are at the same height. When the guide rod 803 leaves the pad 504, under the pulling force of the return spring 808, the two water-locking rings 702 move away vertically, which facilitates the two water-locking rings 702 to move in a staggered manner. Specifically, in this embodiment, when the backrest 300 is in a horizontal position, the center distance between the two water-locking rings 702 is approximately 20 centimeters, so that the two water-locking rings 702 can be aligned with the sides of the buttocks respectively.

[0056] It should be noted that when the backrest 300 is in a vertical and horizontal position, the guide rod 803 is located on the pads 504 on the front and rear sides, respectively. The reason for placing the two water-locking rings 702 at the same height is to ensure that the electromagnetic energy of the two focusing coils 602 is spatially focused at a similar height, acting on the same target muscle group. In addition, when the backrest 300 gradually changes from a vertical to a horizontal position, both focusing coils 602 move forward. This design is because when the user's back gradually lies flat from a vertical position, due to the gradual tilting of the backrest 300 and the effect of gravity, the user's back will be subjected to a downward component force (the gravity on the back can be divided into a pressure perpendicular to the backrest 300 and a downward component force). Under the action of this component force, the user's buttocks will also unconsciously slide forward a certain distance. At this time, the two focusing coils 602 are located directly below the buttocks, and the user does not need to readjust their body posture, thus greatly facilitating the user to switch between the two different postures. It should be added that when the backrest 300 is adjusted from a vertical position to a horizontal position, the water-locking ring 702 moves forward by about 10 centimeters. This distance was obtained through multiple human trials. When the user adjusts from a sitting position to a lying position, their buttocks slide forward by about 10 centimeters, and thus are located just above the two water-locking rings 702.

[0057] It is worth mentioning that, in this embodiment, when the backrest 300 is in a vertical position, the angle between the backrest 300 and the vertical plane is actually 15°. Figure 2 As shown, this design provides support for the user's back, improving comfort. When the backrest 300 is in a horizontal position, the angle between the backrest 300 and the horizontal plane is actually 20°. Figure 3 As shown. In addition, it should be noted that the reason for having the user remain in a lying position for buttock shaping treatment is that when the user lies down, their buttock muscles can relax more, allowing the energy of the focusing coil 602 to act more directly on the deep tissues; on the other hand, when the user lies down, the contact area between the buttocks and the seat is larger, and the user's body is easier to keep stable, which is conducive to the precise positioning of the energy of the focusing coil 602 on both sides of the buttocks.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used merely to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes the element.

[0059] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
