Abstract
Description
Technical Field
[0001] This application relates to the field of rehabilitation therapy equipment technology, and in particular to a pelvic floor magnetic therapy device. Background Technology
[0002] Sexual dysfunction is a clinical condition characterized by painful intercourse, difficulty achieving orgasm, and decreased sexual pleasure. The incidence of sexual dysfunction in women increases significantly after childbirth compared to before pregnancy. During pregnancy, the uterus enlarges, the pelvis shifts, and the pelvic floor muscles are subjected to continuous pressure. The pelvic floor fascia and ligaments are gradually stretched. After vaginal delivery, further damage to the fascia and ligaments occurs, leading to decreased elasticity and reduced vaginal tightness, thus causing sexual dysfunction.
[0003] Currently, the treatment of postpartum sexual dysfunction often combines electrical stimulation therapy with pelvic floor muscle training. Pelvic floor muscle training is a common method for treating pelvic floor dysfunction, involving patients training their pelvic floor muscles themselves. Electrical stimulation mainly involves inserting a vaginal probe to stimulate neuromuscular nerves, improve circulation, and thus restore pelvic floor muscle function. However, electrical stimulation is primarily invasive, with drawbacks such as a limited range of stimulation, a high risk of pain, and an increased risk of infection for patients. Summary of the Invention
[0004] In order to improve the problems of small range, easy pain and increased risk of infection in the treatment of postpartum sexual dysfunction by electrostimulation therapy, this application provides a pelvic floor magnetic therapy device.
[0005] This application provides a pelvic floor magnetic therapy device, which adopts the following technical solution: A pelvic floor magnetic therapy device includes a chair, an electromagnetic generating component built into the chair, and a drive component fixed in the chair for driving the electromagnetic generating component to rotate. The electromagnetic generating component includes a mounting plate built into the chair, a capacitor fixed in the mounting plate, a current generator connected to the capacitor, and a stimulation coil connected to the current generator. The stimulation coil is in the shape of a planar spiral.
[0006] By adopting the above technical solution, the capacitor provides current to the stimulation coil through the current generator, generating a magnetic field at the stimulation coil. The magnetic field penetrates the body and acts on the patient's pelvic floor muscle tissue, generating electrical excitation of the pelvic floor nerves, strengthening the sensory stimulation of the pelvic floor muscles, improving muscle contraction ability, and improving pelvic floor muscle function, thereby playing a therapeutic role in postpartum sexual dysfunction. Since the electrical excitation of the nerves is an induced current, it is not sufficient to produce pain excitation, so painless treatment can be performed. The planar spiral-shaped stimulation coil expands the coverage area of the magnetic field, and the driving component drives the stimulation coil to rotate, improving the uniformity of the magnetic field strength, which is conducive to obtaining better therapeutic effects.
[0007] Optionally, the chair seat is provided with armrests on both sides, and the armrests are provided with a pressure therapy component. The pressure therapy component includes an airbag with one end fixedly connected to one side of the armrest. The airbag is used to push and squeeze the patient's pelvic area.
[0008] By employing the above-mentioned technical solution, the airbag exerts force and compression on the pelvic area of the patient sitting in the chair through periodic expansion and contraction movements, thereby promoting hip bone repair and helping the pelvis return to its normal position. This indirectly relieves the muscles in the pelvic floor area. At the same time, the electromagnetic pulses generated by the stimulation coil act on the pelvic floor neuromuscular tissue, thereby training the pelvic floor muscles, relieving pelvic pain, inhibiting bladder detrusor muscle contraction, and promoting blood circulation. The combined effect of the airbag's pushing and squeezing and the magnetic field stimulation further accelerates the recovery of postpartum sexual dysfunction, alleviates postpartum discomfort, and avoids the long-term burden of postpartum sequelae on the patient.
[0009] Optionally, the pressure therapy component includes an air chamber disposed inside the armrest, the other end of the airbag is connected to the air chamber, a push block is disposed inside the air chamber, the push block is slidably connected to the air chamber, and the drive component drives the push block to perform reciprocating linear motion.
[0010] By adopting the above technical solution, the pusher divides the air chamber into two spaces. The side of the pusher facing the airbag and the air chamber form a closed space. When the pusher moves towards the airbag interface, the closed space is compressed and its volume decreases, allowing gas to flow into the airbag. The airbag expands and applies pressure to the patient's pelvic area for treatment. When the pusher moves away from the airbag interface, the closed space expands, gas flows back into the air chamber, the airbag retracts, and the pusher moves back and forth in a straight line, thereby causing the airbag to periodically expand and retract, achieving the therapeutic effect.
[0011] Optionally, the drive assembly includes a drive motor fixedly connected inside the seat and a mounting plate; the drive motor is driven by a worm gear on one side, the axis of which is parallel to the output shaft of the drive motor; the worm gear meshes with a worm wheel, and a rotating shaft passes through the center of the worm wheel; a cam is fixedly connected to the rotating shaft; a strip-shaped clearance groove is formed on the air chamber; one end of the push block is fixedly connected to a connecting plate that passes through the clearance groove and extends to the outside of the air chamber; the outer peripheral surface of the cam abuts against the connecting plate; a return spring is fixedly connected to the push block, and the other end of the return spring is fixedly connected to the inner wall of the end face of the air chamber.
[0012] By adopting the above technical solution, the drive motor drives the mounting plate to rotate, thereby driving the stimulation coil to rotate; while the drive motor rotates, through the cooperation of the worm gear, worm wheel, cam and connecting plate, it simultaneously drives the push block to perform linear reciprocating motion inside the air chamber. The ingenious structure ensures that the magnetic field rotation and airbag compression therapy are carried out simultaneously, thus improving the treatment effect.
[0013] Optionally, a stepped groove is formed on the side wall of the air chamber along its own length direction, and stepped slides are provided on both sides of the push block, with the stepped slides correspondingly embedded in the stepped grooves for sliding.
[0014] By adopting the above technical solution, the stepped slide is embedded in the stepped slide groove for sliding, which improves the stability of the pusher sliding in the air cavity, thereby ensuring the normal operation of the airbag and improving the reliability of the structure.
[0015] Optionally, elastic sealing strips are fixed to both sides of the connecting plate, and the other end of the elastic sealing strip is fixed to the air cavity, thereby sealing the clearance groove.
[0016] By adopting the above technical solution, the elastic sealing strip has the ability to deform and follow. When the connecting plate drives the push block to slide linearly back and forth, the elastic sealing strip follows the movement, always sealing the clearance groove of the air cavity, which improves the reliability of the structure and ensures the normal operation of the airbag.
[0017] Optionally, the chair seat is provided with a heat dissipation component, which is used to dissipate heat and cool the stimulation coil.
[0018] By adopting the above technical solution, the planar spiral-shaped stimulation coil generates heat due to resistance when energized. The heat dissipation component is installed inside the chair seat to cool down the heat at the stimulation coil, improving heat dissipation and ensuring the normal operation of the device.
[0019] Optionally, the heat dissipation assembly includes an air tube that is fixed to one end of the air cavity away from the airbag interface, with the other end of the air tube aligned with the position of the stimulation coil.
[0020] By adopting the above technical solution, the trachea is connected to the air chamber. When the pusher inflates and deflates the airbag, it can simultaneously act on the space formed by the side of the pusher facing the trachea, the air chamber, and the trachea. When the pusher moves toward the trachea, the gas in the space is expelled and blown to the stimulation coil by the trachea, thereby carrying away some heat. When the pusher moves away from the trachea, the space increases, and air is drawn in from the outside, causing airflow at the stimulation coil, which also helps to lower the temperature and dissipate heat.
[0021] Optionally, the trachea is a variable diameter tube, with the diameter of the trachea gradually decreasing from the end near the air chamber to the end near the stimulation coil.
[0022] By adopting the above technical solution, the variable diameter tube causes the cross-section through which the air flows from the air cavity to the position of the stimulation coil to continuously decrease, and the flow velocity to continuously increase, eventually being sprayed onto the stimulation coil at a greater speed, thereby enhancing the heat dissipation effect.
[0023] Optionally, the current generator may be a pulse current generator.
[0024] By adopting the above technical solution, the pulse current generator produces a pulse current, which in turn generates a pulse magnetic field at the stimulation coil. The constantly changing pulse magnetic field acts on the patient's pelvic floor muscle tissue, which is beneficial for both the deep and superficial muscles of the pelvic floor to receive sensory stimulation, accelerate blood flow, and improve the recovery and treatment effect.
[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a chair, an electromagnetic generator, and a drive component, the patient can sit on the chair for treatment. The stimulation coil inside the chair generates a magnetic field, which penetrates the body and acts on the patient's pelvic floor muscle tissue, generating electrical excitation of the pelvic floor nerves, strengthening the sensory stimulation of the pelvic floor muscles, improving muscle contraction ability, and improving pelvic floor muscle function, thereby playing a therapeutic role in postpartum sexual dysfunction. The drive component drives the stimulation coil to rotate, improving the uniformity of the magnetic field strength, which is conducive to obtaining better treatment results.
[0026] 2. By setting up a pressure therapy component, the drive component moves the airbag to perform periodic expansion and contraction movements, applying force and compression to the pelvic area of the patient sitting in the chair, in order to promote hip bone repair, help the pelvis return to its normal position, and indirectly relieve the muscles in the pelvic floor area, thereby improving the muscle contraction ability. The combined effect of the airbag's pushing and squeezing and the magnetic field stimulation therapy further improves the treatment effect on postpartum sexual dysfunction.
[0027] 3. By setting up a heat dissipation component, the pusher can simultaneously blow and suck air at the stimulation coil position while inflating and deflating the airbag, thereby cooling the heat at the stimulation coil, improving heat dissipation and ensuring the normal operation of the device.

[0030] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0031] This application discloses a pelvic floor magnetic therapy device, including a seat 1, an electromagnetic generation component 2, a driving component 3, a pressure therapy component 4, and a heat dissipation component 5. (See also...) Figure 1 and Figure 2 The chair 1 has armrests 11 on both sides, and the patient sits on the chair 1 during treatment. The lower part of the chair 1 is a hollow structure with an insertion port on one side, which is covered by a cover plate 12. The electromagnetic generator 2 is located in the cavity of the chair 1, and generates a magnetic field that directly acts on the patient's pelvic floor muscles, improving muscle activity and pelvic floor function, thereby achieving the treatment of sexual dysfunction. The drive component 3 is used to drive the electromagnetic component to rotate, making the magnetic field distribution more uniform. The pressure therapy component 4 is located on one side of the armrest 11 and is used to perform compression therapy on the patient. (Refer to...) Figure 2 and Figure 3 The heat dissipation component 5 is installed inside the cavity of the seat 1 to cool down the electromagnetic generator component 2 during operation.
[0032] Reference Figure 2 and Figure 3 The electromagnetic generator assembly 2 includes a mounting plate 21, which is horizontally disposed in the cavity of the chair seat 1. A support base 13 is fixedly connected inside the chair seat 1. The mounting plate 21 and the support base 13 are rotatably disposed. A capacitor 22 is fixedly connected to the side of the mounting plate 21 away from the support base 13. The capacitor 22 is used to provide electrical energy to the electromagnetic generator assembly 2. The capacitor 22 is connected to a current generator 23 through wires. The current generator 23 is connected to a stimulation coil 24. The stimulation coil 24 is in the shape of a circular planar spiral and is installed in a protective box 25, which is fixed to the mounting plate 21.
[0033] The current generator 23 is a pulse current generator. The pulse current flows through the stimulation coil 24, thereby generating a pulse magnetic field at the stimulation coil 24. According to Faraday's principle of electromagnetic induction, the changing pulse magnetic field acts on the patient's pelvic floor muscle tissue, generating an induced current in the human body and enhancing the sensory stimulation of the pelvic floor muscle tissue. At the same time, because the induced current does not reach the pain excitation threshold, it will not cause pain.
[0034] Since the magnetic field strength generated by the planar spiral-shaped stimulation coil 24 may be uneven, in order to achieve better treatment results, a drive assembly 3 is set at the bottom of the chair seat 1. The drive assembly 3 includes a drive motor 31, and the output end of the drive motor 31 is fixedly connected to the mounting plate 21. The drive motor 31 drives the mounting plate 21 to rotate, thereby driving the stimulation coil 24 to rotate, so that the generated magnetic field acts more evenly on the patient's pelvic floor muscles.
[0035] Reference Figure 2 and Figure 3 The pressure therapy component 4 includes an airbag 41, which is fixed to one side of the armrest 11. The airbag 41 pushes and squeezes the pelvic area of the patient sitting on the seat 1 through periodic expansion and contraction movements, so as to relieve the pelvic floor muscle tissue near the pelvis, promote blood circulation, and improve muscle contraction ability.
[0036] Reference Figure 2 and Figure 3 The expansion and contraction of the airbag 41 are achieved by the cooperation of the air chamber 42 and the push block 43. The air chamber 42 is a hollow structure, fixedly connected inside the handrail 11. One end of the airbag 41 passes through the side wall of the handrail 11 and communicates with the air chamber 42, with the interface of the airbag 41 located near one end face of the air chamber 42. The push block 43 is fitted to the hollow shape of the air chamber 42, slidably connected within the air chamber 42, and the side of the push block 43 near the interface of the airbag 41 forms a sealed space with the air chamber 42. (Refer to...) Figure 4 A stepped slide groove 421 is provided on the side wall of the air cavity 42 along its own length. The cross section of the stepped slide groove 421 is a "T" shaped structure. Stepped slides 431 are provided on both sides of the push block 43. The stepped slides 431 are slidably disposed in the stepped slide groove 421, thereby ensuring the stability of the sliding connection between the push block 43 and the air cavity 42.
[0037] Reference Figure 2 and Figure 3A connecting plate 44 is fixedly connected to one side of the push block 43. A strip-shaped clearance groove 422 is opened at the bottom of the air chamber 42. The connecting plate 44 passes through the clearance groove 422 and extends to the outside of the air chamber 42. The drive assembly 3 also includes a worm gear 32, which is vertically arranged and its axis is parallel to the axis of the output shaft of the drive motor 31. One end of the worm gear 32 is connected to the output shaft of the drive motor 31 via belt drive. A worm wheel 33 is meshed on the worm gear 32. A rotating shaft 34 passes through the center of the worm wheel 33. A cam 35 is coaxially fixed to the rotating shaft 34. The outer peripheral surface of the cam 35 presses against the connecting plate 44. A return spring 45 is fixedly connected to the side of the push block 43 away from the airbag 41 interface. The other end of the return spring 45 is fixedly connected to the inner wall of one end of the air chamber 42.
[0038] The drive motor 31 drives the worm gear 32 to rotate, which in turn drives the worm wheel 33 to mesh and rotate. The rotating worm wheel 33 drives the cam 35 to rotate via the shaft 34. The rotating cam 35 drives the push block 43 to reciprocate linearly within the air chamber 42 via the connecting plate 44. Under the action of the return spring 45, the push block 43 always presses the connecting plate 44 against the outer circumferential surface of the cam 35. When the push block 43 moves towards the interface of the airbag 41, the volume of the sealed space formed by the push block 43 and the air chamber 42 decreases, and gas flows into the airbag 41 at the end of the air chamber 42, causing the airbag 41 to inflate and push and compress the patient's pelvic area. When the push block 43 slides away from the interface of the airbag 41, the volume of the sealed space formed by the push block 43 and the air chamber 42 increases, and gas flows back into the air chamber 42, causing the airbag 41 to retract. The cam 35 rotates continuously, thereby driving the airbag 41 to perform periodic expansion and contraction movements, achieving pressure therapy on the patient's pelvic area.
[0039] Elastic sealing strips 46 are fixed to both sides of the connecting plate 44, and the other end of the elastic sealing strip 46 is fixed to the air cavity 42. The elastic sealing strip 46 always follows the movement when the connecting plate 44 and the push block 43 slide, thus sealing the clearance groove 422 at the bottom of the air cavity 42.
[0040] Reference Figure 3The seat 1 is equipped with a heat dissipation component 5, which includes an air pipe 51. One end of the air pipe 51 is fixedly connected to the end face of the air chamber 42 away from the air bag 41, and the other end of the air pipe 51 is aligned with the stimulation coil 24. A pusher block 43 slides within the air chamber 42. When the pusher block 43 slides towards the air pipe 51, it compresses some of the gas inside the air chamber 42 and blows it through the air pipe 51 onto the stimulation coil 24, carrying away some of the heat generated by the stimulation coil 24 when energized, thus cooling it down. When the pusher block 43 slides away from the air pipe 51, it draws outside air into the air chamber 42 through the air pipe 51, creating airflow at the opening of the air pipe 51, i.e., the stimulation coil 24, which also serves to cool the air. The air pipe 51 is a variable diameter pipe, with its diameter gradually decreasing from the end near the air chamber 42 to the end near the stimulation coil 24, thereby increasing the airflow speed at the stimulation coil 24 and improving the heat dissipation effect.
[0041] The implementation principle of this application embodiment is as follows: When the patient is treated, the stimulation coil 24 is energized to generate a pulsed magnetic field. The changing pulsed magnetic field acts on the patient's pelvic floor muscle tissue, generating an induced current, which strengthens the sensory stimulation of the pelvic floor muscle tissue and plays a therapeutic role in the patient's postpartum sexual dysfunction. The drive motor 31 drives the stimulation coil 24 to rotate through the mounting plate 21, so that the pulsed magnetic field acts more evenly on the patient's pelvic floor muscles.
[0042] During rotation, the drive motor 31, in conjunction with the cam 35 and the connecting plate 44, drives the push block 43 to slide within the air chamber 42. As the push block 43 slides towards the airbag 41 interface, the volume of the space enclosed by the side of the push block 43 facing the airbag 41 and the air chamber 42 decreases, allowing gas to enter the airbag 41. The airbag 41 inflates, pushing and squeezing the patient's pelvic area, providing a massage and soothing effect. Simultaneously, the volume of the space enclosed by the side of the push block 43 facing the trachea 51 and the air chamber 42 increases accordingly, causing air to be drawn in at one end of the trachea 51, disturbing the air at the stimulation coil 24 and providing a cooling effect. When the push block 43 moves away from the airbag 41 interface, i.e., towards the trachea 51, the airbag 41 retracts, and some air from the air chamber 42 is ejected through the trachea 51 onto the stimulation coil 24, similarly carrying away some heat from the stimulation coil 24, thus providing a heat dissipation effect and ensuring the normal operation of the electromagnetic generator component 2.
[0043] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
