Description

[Technical Field]

[0001] The present invention relates to a pelvic floor muscle massager. [Background technology]

[0002] The pelvic floor muscles, which are located at the bottom of the pelvis, and the adductor muscles connected to them play important roles, such as tightening the urethra and preventing urinary incontinence. Therefore, training the pelvic floor muscles and adductor muscles using an EMS (Electro-Mechanical System) exercise device for the pelvic floor muscles, such as that shown in Patent Document 1, has been proposed. Such an EMS exercise device for the pelvic floor muscles is made to a waterproof specification (e.g., IP54) and includes an EMS unit that is raised in the center and applies electrical stimulation to the user's pelvic floor muscles at positions corresponding to the user's pelvic floor muscles, a pair of buttock depressions formed at opposing bottoms of the EMS unit where the user's buttocks are placed, an operating unit including an ON / OFF indicator, a pulse intensity selector switch, and a power switch, and a rechargeable battery that supplies power to the EMS unit. The EMS unit is entirely molded from silicone rubber and includes multiple carbon graphene electrodes that apply electrical stimulation to the entire pelvic floor muscles. With this configuration, after taking a bath or other such action, the user sits on the EMS pelvic floor muscle exercise device placed on a chair, places their buttocks on the pair of buttock depressions, turns on the power switch, and presses the pulse intensity selector switch to set the EMS mode, which activates the EMS unit for a predetermined period of time and performs muscle strengthening exercises for the pelvic floor muscles.

[0003] [Patent Document 1] Japanese Patent Application Publication No. 2023-157354 Summary of the Invention [Problem to be solved by the invention]

[0004] The above-mentioned pelvic floor muscle EMS exercise device is used while the user is seated on the device placed on a chair, such as after taking a bath. Therefore, if the user's buttocks come into contact with the multiple carbon graphene electrodes that directly provide electrical stimulation, and sufficient conductivity is not maintained between the electrodes and the skin, the user may experience a persistent tingling pain, as if the skin is being pricked. In such cases, it may be possible to use the pelvic floor muscle EMS exercise device in water to ensure sufficient conductivity between the electrodes and the skin. However, the above-mentioned EMS exercise device for the pelvic floor muscles is made to specifications that make it waterproof for everyday use (e.g., IP54), and does not have a sufficient waterproof structure to allow the device to be used underwater.

[0005] In consideration of the above problems, an object of the present invention is to provide a pelvic floor muscle massager that can be used underwater, such as in a bathtub. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the pelvic floor muscle massager of the present invention is configured to include: an upper cover molded from electrically insulating silicone rubber and having a raised portion that rises diagonally upward from one end and a plurality of slits formed in the raised portion through which fluid can pass; a lower cover molded from electrically insulating silicone rubber and joined to the underside of the upper cover and having a plurality of slits through which fluid can pass; an operating unit disposed on a sloped portion that continues to one end of the raised portion of the upper cover; a pair of current-carrying portions formed from conductive silicone rubber on the sloped portions on both sides of the operating portion of the upper cover and on the base that continues to the sloped portions, for electrically stimulating the adductor muscles and the pelvic floor muscles; a printed circuit control board disposed in the internal space formed between the upper cover and the lower cover and having a control unit that drives and controls at least one pair of current-carrying portions based on command signals from the operating portion; and a control box that hermetically houses all of the above. The operating unit may also have a power button, an LED lamp display, an intensity switch button that increases or decreases the intensity of the electrical stimulation applied to the adductor muscles and pelvic floor muscles using a pair of electrical conduction units, and a charging port with a waterproof plug. The control box may include a box base that is arranged opposite the operating unit on the raised portion of the upper cover and fixed to a base that is fixed to the inner periphery of the upper cover, a box cover that is arranged between the operating unit and the inner periphery of the upper cover and the box base and cooperates with the box base to form an airtight space, and a sealing seal that is arranged between the connecting end at the bottom of the box cover and the connecting end of the box base. Furthermore, a through-hole that passes through the upper and lower covers may be formed on the center line of the upper cover between one electrode and the other pelvic floor muscle electrode of a pair of current-carrying parts that are near the other end of the raised part of the upper cover.A non-slip pattern of multiple concentric stripes may be formed around the through-hole on the underside of the lower cover. The control unit may form a group of drive command signals to the pair of conductive parts so that they electrically stimulate the adductor muscles and pelvic floor muscles at a predetermined intensity based on a group of request signals to increase or decrease the intensity of the electrical muscle stimulation from the intensity switch button on the operating part, and supply these signals to the EMS control part. [Effects of the Invention]

[0007] According to the pelvic floor muscle massager of the present invention, the control box is disposed in the internal space formed between the upper cover and the lower cover, and houses in a sealed state a printed circuit control board having a control unit that drives and controls at least a pair of current-carrying parts based on command signals from the operating part, and a battery that supplies power to the printed circuit control board, so that the pelvic floor muscle massager can be used underwater, such as in a bathtub.

[0009] FIG. 1 shows the appearance of an example of a pelvic floor muscle massager according to the present invention.

[0010] Pelvic floor muscle massager 10 (hereinafter also referred to as massager 10) is configured with, for example, an upper cover 10A molded from electrically insulating silicone rubber and having a raised portion 12 that rises diagonally upward from one end, a lower cover 10B (see Figures 3 and 4) molded from electrically insulating silicone rubber and joined to the approximately circular underside of upper cover 10A to form the approximately circular underside of massager 10, a control box 20 that is arranged in the internal space formed between upper cover 10A and lower cover 10B and that houses a printed circuit control board 22 (described later) and the like, and an operating unit 14 that is formed on the sloped portion of raised portion 12 of upper cover 10A near the above-mentioned one end.

[0011] As shown in Fig. 2, an operating unit 14 is formed on a sloped surface connected to the one end of raised portion 12 of upper cover 10A so as to pass through the center line of upper cover 10A which passes through the center of through-hole 10H. As shown in Fig. 5 and enlarged views in Fig. 6, operating unit 14 has, from top to bottom of the sloped surface, a power button 14PB, an LED lamp display unit 14L, intensity switching buttons including an intensity switch + button 14SW1 that increases the intensity of the electrical stimulation applied to muscles by current-carrying units 10RE and 10LE (described later) and an intensity switch - button 14SW2 that decreases the intensity of the electrical stimulation, and a charging port 14CP with a waterproof plug.

[0012] At the top of the raised portion 12 of the upper cover 10A, away from the operating unit 14, a slit group 12AS1 is formed, as shown in FIG. 2, with multiple slits of different lengths spaced apart and intersecting the center line of the upper cover 10A. The slit group 12AS1 allows fluids such as water and air to flow from the outside into the internal space or from the internal space to the outside through the upper cover 10A, as indicated by the arrows in FIG. 4. Slits 10AS2, 10AS3, and 10AS4, each longer than the multiple slits in slit group 12AS1, are formed at positions spaced apart from slit group 12AS1 on the inclined surface of the raised portion 12 of the upper cover 10A that slopes toward the other end. Slit 10AS3 is formed along the center line of the upper cover 10A. Slits 10AS2 and 10AS4 are located at positions spaced apart from slit 10AS3, with slit 10AS3 between them. A soft cover 28 extending along the inclined surface is supported on upper cover 10A at a position a predetermined distance below slits 10AS3, 10AS2, and 10AS4 in upper cover 10A. Soft cover 28 is a member that conceals the interior so that it cannot be seen through slits 10AS3, 10AS2, and 10AS4.

[0013] A pair of current-carrying portions 10RE and 10LE that electrically stimulate muscles are formed on slopes 10R and 10L formed on both sides of operating portion 14 of raised portion 12 of upper cover 10A, and on the bases connected to slopes 10R and 10L. Current-carrying portions 10RE and 10LE are molded integrally with the rest of upper cover 10A, which is molded from electrically insulating silicone rubber, for example, by two-color molding. The current-carrying portion 10RE is, for example, an electrode portion formed of conductive silicone rubber (conductive film) and laminated with two layers of film. As shown in Fig. 1, the current-carrying portion 10RE formed on the sloped surface portion 10R extends and spreads toward the outer peripheral edge of the upper cover 10A, and spreads along the outer peripheral edge of the upper cover 10A to the vicinity of the through-hole 10H. Pelvic floor muscle electrode section 10RS, which is connected to the electrode section of sloped section 10R, is integrally formed on the base of current-carrying section 10RE that widens toward the other end of massager 10. As will be described later, current-carrying section 10RE formed on sloped section 10R corresponds to the adductor muscles connected to the pelvic floor muscles of the user's body, and pelvic floor muscle electrode section 10RS corresponds to the pelvic floor muscles of the user's body. The current-carrying portion 10LE is an electrode portion formed, for example, from conductive silicone rubber (conductive film) and laminated with two layers of film. As shown in Fig. 1, the current-carrying portion 10LE formed on the sloped portion 10L extends and spreads toward the outer peripheral edge of the upper cover 10A, and spreads along the outer peripheral edge of the upper cover 10A to the vicinity of the through-hole 10H.

[0014] Pelvic floor muscle electrode section 10LS, which is connected to the electrode section of the sloped section, is formed on the base of current-carrying section 10LE, which is formed on sloped section 10L and spreads out toward the other end of massager 10. As will be described later, current-carrying section 10LE formed on sloped section 10L corresponds to the adductor muscles connected to the pelvic floor muscles of the user's body, and pelvic floor muscle electrode section 10LS corresponds to the pelvic floor muscles of the user's body. The current-carrying units 10RE and 10LE are each electrically connected via lead wires 30 to a printed circuit control board 22 (see FIG. 4) described later.

[0015] A circular through-hole 10H that penetrates the upper cover 10A and the lower cover 10B is formed on the center line of the upper cover 10A between the pelvic floor muscle electrode 10RS and the pelvic floor muscle electrode 10LS near the other end of the raised portion 12 of the upper cover 10A. A hook or the like can be attached to the periphery of the through-hole 10H to hang the massager 10 after use so that any water on the massager 10 can dry naturally.

[0016] As shown in FIGS. 3 and 4, the outer peripheral edge of the lower cover 10B and the peripheral edge of the through-hole 10H are joined to the lower surface of the upper cover 10A. 7, the lower cover 10B is molded into a substantially disk-like shape from electrically insulating silicone rubber, and has a slit 10BS2 extending radially from the periphery of the through-hole 10H along the center line of the lower cover 10B, and slits 10BS1 and 10BS3 formed adjacent to both sides of the slit 10BS2. The slits 10BS1, 10BS2, and 10BS3 allow fluids such as water and air to flow from the outside into the internal space or flow from the internal space to the outside through the lower cover 10B, as indicated by the arrows in FIG.

[0017] A plurality of concentric striped anti-slip portions 10BFi (i = 1 to n, n is an integer) are formed around through-holes 10H on the underside of lower cover 10B. These anti-slip portions 10BFi prevent massage device 10 from slipping on the bottom of the bathtub when massage device 10 is used in the bathtub. As shown in Fig. 8, lower cover 10B and upper cover 10A are joined together by fitting and positioning a plurality of connecting pieces 32 provided on the upper end of lower cover 10B into connecting recesses provided in upper cover 10A corresponding to the above-mentioned plurality of connecting pieces 32.

[0018] As shown in Figure 8, the control box 20 is configured to include a box base 18 that is arranged opposite the operating unit 14 on the above-mentioned raised portion 12 and is fixed to a base 30 that is fixed to the inner periphery of the upper cover 10A with a plurality of male screws MSC, a box cover 16 that is arranged between the operating unit 14 on the raised portion 12 and the inner periphery of the upper cover 10A and the box base 18, and that cooperates with the box base 18 to form a sealed closed space, and an O-ring 20L that serves as a sealing seal and is arranged between the lower connecting end of the box cover 16 and the upper connecting end of the box base 18.

[0019] The operation unit 14 is disposed at the top end of the box cover 16. A charging port 14CP with a waterproof plug is provided at a position close to one end of the box cover 16, separate from the intensity switching button 14SW2 of the operation unit 14.

[0020] Within the sealed closed space, a battery 26, for example, a lithium battery which is a secondary battery, the vibration motor 24, and the printed circuit control board 22 are fixed to the box base 18. The printed circuit control board 22, the battery 26, the vibration motor 24, and the operation unit 14 are electrically connected to one another. The printed circuit control board 22 is provided with, for example, an ON / OFF switch element, an LED lamp, and two tactile switches corresponding to the power button 14PB, the LED lamp display unit 14L, and the intensity switching button of the operation unit 14, which are arranged on the box cover 16. As a result, the printed circuit control board 22, the battery 26, the vibration motor 24, etc. are sealed and housed within the control box 20, which has a waterproof structure, so that the massager 10 can be used even underwater in a bathtub.

[0021] In addition to the above configuration, an example of the massager 10 has, as shown in FIG. A control unit 50 is mounted on the printed circuit control board 22 .

[0022] 9, a command signal CD1 representing an ON / OFF command is supplied to the control unit 50 from the power button 14PB of the operation unit 14, and a group of request signals CQ for increasing and decreasing the intensity of Electrical Muscle Stimulation (EMS) (hereinafter also referred to as EMS) from the intensity switch + button 14SW1 and the intensity switch − button 14SW2. Furthermore, when the power button 14PB is in the OFF state and a charging adapter 52 connected to a predetermined power source is connected to the charging port 14CP, a detection signal Sv representing the voltage based on negotiation (specific communication between the power supply side and the power receiving side before power is supplied) is supplied to the control unit 50.

[0023] The control unit 50 includes a memory section 50M for storing program data for controlling the rotation of the vibration motor 24 described later, program data for controlling the electrical muscle stimulation (EMS) (hereinafter also referred to as EMS) of the current-carrying sections 10RE and 10LE, program data for controlling the lighting of light-emitting diodes (hereinafter also referred to as LEDs), program data for controlling the charging of the battery 26, and the like.

[0024] When the power button 14PB is pressed and held for, for example, about two seconds, the control unit 50 supplies a drive command signal CR to the motor drive control unit 54 to operate the counterweight in the vibration motor 66 based on a command signal CD1 representing an ON state command from the power button 14PB. As a result, the motor drive control unit 54 supplies a drive control signal to the vibration motor 24 to rotate the counterweight of the drive motor 66 based on the drive command signal CR. As a result, the upper cover 10A and the lower cover 10B of the massager 10 vibrate only twice.

[0025] At this time, the control unit 50 supplies a control signal CL to the LED lighting control unit 58. Based on the control signal CL, the LED lighting control unit 58 controls the LED circuit unit 64 to perform an operation to light up the LED lamp display unit 14L. Meanwhile, when the power button 14PB is pressed and held for, for example, about two seconds during operation, the control unit 50 supplies a drive command signal CR to the motor drive control unit 54 to operate the counterweight in the vibration motor 66 based on a command signal CD1 representing an OFF state command from the power button 14PB. This causes the upper cover 10A and the lower cover 10B of the massager 10 to vibrate only once. At this time, the control unit 50 supplies a control signal CL to the LED lighting control unit 58. The LED lighting control unit 58 controls the LED circuit unit 64 to turn off the LED lamp display unit 14L based on the control signal CL.

[0026] When power button 14PB is pressed and held for, for example, approximately two seconds, control unit 50 generates a group of drive command signals QCE based on a command signal CD1 representing an ON state command from power button 14PB, and supplies these signals to EMS control unit 56 so that current conduction units 10RE and 10LE initially perform electrical muscle stimulation (EMS) operations on the pelvic floor muscles and adductor muscles of the user's body at an intensity of level 1. EMS control unit 56 generates a group of control signals and supplies these signals to EMS circuit unit 62 so that EMS circuit unit 62 causes current conduction units 10RE and 10LE to each perform an EMS operation at an intensity of level 1 based on the group of drive command signals QCE. EMS circuit unit 62 generates a group of drive control pulse signals CP based on the group of control signals, and supplies these drive control pulse signals CP to current conduction units 10RE and 10LE. For example, the drive control pulse signal CP supplied to the current conducting unit 10RE has a pulse wave (rectangular wave) shape as shown in Fig. 10(A). Fig. 10(A) shows the drive control pulse signal CP, with voltage (V) on the vertical axis and time (T) on the horizontal axis, whose polarity alternates every three pulses. The drive control pulse signal CP supplied to the current conducting unit 10LE has the same amplitude, frequency, and waveform as the pulse signal shown in Fig. 10(A), but has the opposite polarity.

[0027] FIG. 10(B), with voltage (V) on the vertical axis and time (T) on the horizontal axis, shows a striped pattern representing the natural frequency (natural vibration frequency) of the current-carrying units 10RE and 10LE, which changes over time in accordance with the duty cycle of the drive control pulse signal CP (duty ratio % = 0.842 / T × 100, T: period (ms)). The natural frequency (natural vibration frequency) changes, for example, within a frequency band range of approximately 5 Hz to 60 Hz. The EMS circuit unit 62 keeps the frequency (period) of the drive control pulse signal CP constant based on the drive control pulse signal CP, and adjusts the output voltage using pulse width modulation (PWM), which repeatedly changes the duty cycle every period TC (seconds) as shown in FIG. 10(C), which will be described later. Figure 10(C) shows a striped pattern with time on the horizontal axis, indicating that the natural frequencies (natural vibration frequencies) of current-carrying parts 10RE and 10LE are, for example, 2 Hz, 30 Hz & 3 Hz, 10 Hz & 1 Hz, 1.7 Hz & 3.3 Hz (16 Hz to 60 Hz), and 20.4 Hz & 0.2 Hz during the ta, tb, tc, td, and te periods in one cycle, or TC (seconds), respectively. When the natural frequencies (natural vibration frequencies) are, for example, 2 Hz, 30 Hz, 3 Hz, 10 Hz, 1 Hz, 1.7 Hz, and 3.3 Hz, the above-mentioned duty ratios % are 0.1684%, 2.528%, 0.247%, 0.824%, 0.0824%, 0.1432%, and 0.2779%. Next, when the control unit 50 receives a request signal group CQ from the intensity switch button +14SW1 to increase the intensity of the electrical muscular stimulation (EMS), the control unit 50 supplies a control signal group QCE to the EMS control unit 56 based on the request signal group CQ. The EMS control unit 56 generates a control signal group QCE based on the drive command signal group QCE and supplies it to the EMS circuit unit 62 so that the EMS circuit unit 62 causes the current conduction units 10RE and 10LE to perform electrical muscular stimulation (EMS) operations at the requested intensity. The EMS circuit unit 62 generates a drive control pulse signal CP based on the control signal group and supplies the drive control pulse signal CP to the current conduction units 10RE and 10LE. When increasing the intensity of the electrical muscular stimulation (EMS) at a constant frequency, the EMS circuit unit 62 increases the output voltage (amplitude) of the drive control pulse signal CP. When decreasing the intensity of the electrical muscular stimulation (EMS) at a constant frequency, the EMS circuit unit 62 decreases the output voltage (amplitude) of the drive control pulse signal CP. The intensity of the electrical muscle stimulation (EMS) operation may be controlled, for example, in 10 levels. The control unit 50 determines whether the battery 26 can be charged using a predetermined protocol based on the detection signal Sv indicating the voltage from the charging adapter 52, and then supplies a control signal CB to the charging control unit 60 to start power supply. Based on the control signal CB, the charging control unit 60 then supplies a command signal to the charging circuit unit 66 to charge the battery 26. Accordingly, charging of the battery 26 begins. At this time, the control unit 50 supplies a control signal CL to the LED lighting control unit 58 to cause the LED lamp display unit 14L to flash, indicating that charging is in progress. Based on the control signal CL, the LED lighting control unit 58 controls the LED circuit unit 64 to flash the LED lamp display unit 14L. After charging is complete, the LED lamp display unit 14L stops flashing and remains lit.

[0028] To apply electrical muscle stimulation (EMS) to the pelvic floor muscles and adductor muscles of a user using the massager 10, as shown in Figure 11, the user first submerges the massager 10 in a bathtub filled with warm water, sits cross-legged with the right foot RC and the left foot LC, and positions the massager 10 so that the pelvic floor muscles, right buttocks, and left buttocks are in contact with the pelvic floor muscle electrodes 10RS and 10LS of the massager 10, and the adductor muscles LTH and RTH of the right foot are in contact with the current-carrying parts 10RE and 10LE of the massager 10. Next, the user presses and holds the power button 14PB for approximately two seconds. This causes the upper cover 10A and lower cover 10B of the massager 10 to vibrate twice. Next, when the user operates the intensity switch + button 14SW1 and requests a group of signals CQ to increase the intensity of the electrical muscle stimulation (EMS) from the intensity switch + button 14SW1 to the control unit 50, the control unit 50 supplies a group of control signals QCE to the EMS control unit 56 based on the group of request signals CQ. The EMS control unit 56 generates a group of control signals based on the group of drive command signals QCE and supplies them to the EMS circuit unit 62 so that the EMS circuit unit 62 causes the current conduction units 10RE and 10LE to perform electrical muscle stimulation (EMS) operations at the requested increased intensity. The EMS circuit unit 62 generates a drive control pulse signal CP based on the control signal and supplies the drive control pulse signal CP to the current conduction units 10RE and 10LE. This allows electrical muscle stimulation (EMS) of the desired intensity to be applied to the user's adductor muscles and pelvic floor muscles. Even when the intensity switch button 14SW4 is operated, the EMS control unit 56 forms a group of control signals and supplies them to the EMS circuit unit 62 so that the EMS circuit unit 62 causes the current-carrying units 10RE and 10LE to perform electrical muscle stimulation (EMS) operations at the requested weakened intensity based on the drive command signal group QCE.EMS circuit unit 62 generates drive control pulse signals CP based on the control signals and supplies the drive control pulse signals CP to current conduction units 10RE and 10LE, respectively, thereby applying electrical muscle stimulation (EMS) of a desired intensity to the adductor muscles and pelvic floor muscles of the user.

[0029] Therefore, the massager 10 can be used underwater such as in a bathtub, and sufficient conductivity can be maintained between the current-carrying parts 10RE and 10LE and the skin underwater, so that the user does not have to worry about feeling a continuous tingling pain as if the skin is being pricked in small pricks.
