Pelvic floor pressing device
[0001] The present invention relates to a pelvic floor pressing device, and particularly to a self-care type pelvic floor pressing device that can easily loosen and massage the pelvic floor by oneself.
[0002] Urinary incontinence is a urinary disease defined as a state where urine leaks involuntarily, and is classified into types such as stress urinary incontinence (SUI), urge urinary incontinence, and mixed urinary incontinence. These urinary incontinences are often regarded as problems of the elderly, but stress urinary incontinence (SUI), which is defined as a complaint of involuntary urine leakage during exercise, sneezing, or coughing, is common among middle-aged women. And it has been found that the proportion of mixed urinary incontinence complicated with urge urinary incontinence increases with age. Although urinary incontinence is often underestimated because it is not directly related to life-threatening crises, it is desirable to take appropriate preventive measures early because it deteriorates the quality of life regardless of age or degree.
[0003] In Patent Document 1, as a posture correction device, it has at least the length between the pubic bone and the coccyx of the human body in the longitudinal direction, has a width shorter than the length between a pair of sciatic bones of the human body in the width direction with respect to the longitudinal direction, and is placed on the seat surface in a positional relationship where the longitudinal direction coincides with the front-rear direction of the human body. When the human body sits on the seat surface and straddles the convex upper surface, the convex upper surface faces the pubic bone and the coccyx respectively, and a pelvic floor muscle group pressing tool for pressing the pelvic floor muscle group is disclosed.
[0004] Japanese Unexamined Patent Application Publication No. 2017-029180
[0005] Until now, the weakness and hypokinesia of the pelvic floor muscles have been regarded as the main causes of urinary incontinence, and strengthening training of the pelvic floor muscles has been recommended. However, in previous studies, it has been reported that the pelvic floor muscle strength of women with urinary incontinence is not necessarily decreased, and the pelvic floor muscle rigidity value of women with urinary incontinence is high. These suggest that the cause of urinary incontinence (especially stress urinary incontinence) may not be simply due to the weakness of the pelvic floor muscles. Therefore, there is room to consider preventive measures for urinary incontinence from a new perspective focusing on "the hardness of the pelvic floor muscles".
[0006] Furthermore, in individual interventions by specialists in medical institutions, pelvic floor muscle palpation is often followed by pelvic floor muscle training, massage, and stretching. However, this method involves specialists manually touching the perineum, vagina, and anal area, which can potentially damage the subject's sense of shame and self-esteem.
[0007] The pelvic floor muscle pressing device described in Patent Document 1 is a device intended to correct the posture of the human body from outside the body by actively moving the diaphragm, transversus abdominis, multifidus, erector spinae, etc., by pressing on the pelvic floor muscles. The pelvic floor muscle pressing device described in Patent Document 1 has a configuration that, in the longitudinal direction, has at least the length between the pubic bone and the coccyx of the human body, and also presses on the anus, which is located in the center. In other words, it is not configured to target and press on the area enclosed by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx. Therefore, it cannot loosen the pelvic floor area that causes urinary leakage and is not useful for improving urinary incontinence.
[0008] This invention is a self-care type pelvic floor pressure device that allows you to easily loosen and massage the pelvic floor, including the pelvic floor muscles, by yourself.
[0009] The pelvic floor pressure device of the present invention is a palm-sized pelvic floor pressure device (10) used by a user below the pelvic floor, such as a pelvic floor self-care device, and comprises a plurality of raised areas (11, 12) corresponding to the region (41, 42) surrounded by the left ischial ramus (33), left ischial tuberosity (34), left sacrotuberous ligament (35), anus (31), and coccyx (32) of the user's left pelvic floor, and the user's right pelvic floor The device comprises a plurality of raised portions (13, 14) corresponding to the region (43, 44) enclosed by the right ischial ramus (36), the right ischial tuberosity (37), the right sacrotuberous ligament (38), the anus (31), and the coccyx (32), and is placed on a seat surface, characterized in that when a user sits on the device, each of the raised portions (11-14) presses against the respective regions (41-44) of the left and right pelvic floors.
[0010] The bottom surface of the device, which is the side that rests on the seat S, may be formed in a convex shape in the front-to-back direction of the user when the user is sitting on the device.
[0011] The plurality of protrusions (11, 12) corresponding to the left pelvic floor include a first left protrusion (large) (11) corresponding to the region (41) enclosed by the left ischial tuberosity (34) of the left pelvic floor, the left sacrotuberous ligament (35), the anus (31), and the coccyx (32), and a second left protrusion (small) (12) corresponding to the region (42) between the left ischial ramus (33) of the left pelvic floor and the anus (31), and being smaller than the first left protrusion (11), and the right bone The plurality of protrusions (13, 14) corresponding to the base of the pelvis may be configured to include a first right protrusion (large) (13) corresponding to the region (43) enclosed by the right ischial tuberosity (37) of the right pelvic floor, the right sacrotuberous ligament (38), the anus (31), and the coccyx (32), and a second right protrusion (small) (14) corresponding to the region (44) between the right ischial ramus (36) of the right pelvic floor and the anus (31), and which is smaller than the first right protrusion (13).
[0012] The first left protrusion may be equipped with a pressure sensor inside that detects the pressure applied by the first left protrusion to the soft tissue (skin, fat, fascia, muscle) located at the left pelvic floor, and the first right protrusion may be equipped with a pressure sensor inside that detects the pressure applied by the first right protrusion to the soft tissue (skin, fat, fascia, muscle) located at the right pelvic floor, and communication means may be provided to transmit pressure notification information to notify the pressure applied to each of the soft tissues based on the detection signals detected by each of the pressure sensors.
[0013] The system may include a muscle stiffness information acquisition means that calculates a numerical value corresponding to the muscle stiffness of the pelvic floor muscles contained in each of the soft tissues based on the detection signal detected by each of the pressure sensors and acquires it as muscle stiffness information, and the communication means may be configured to transmit muscle stiffness notification information to notify the muscle stiffness of the pelvic floor muscles contained in each of the soft tissues based on the muscle stiffness information acquired by the muscle stiffness information acquisition means.
[0014] The device may also include a means for applying vibration stimulation to the right and left pelvic floors.
[0015] According to the pelvic floor pressure device of the present invention, when the user sits on the device and applies their weight, multiple raised sections apply downward pressure to the left and right areas of the pelvic floor, which are surrounded by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx. This effectively relaxes the area and prevents urinary incontinence. Furthermore, its compact size, which fits in the palm of the hand, makes it easy to carry and use discreetly without being noticed by others, making it easy to use in various locations and continue using it regularly.

[0017] Embodiments of the present invention will be described with reference to the drawings. However, the embodiments described below are merely illustrative, and there is no intention to exclude various modifications or applications of techniques not explicitly stated below. That is, the present invention can be implemented in various ways (such as combining each embodiment) as long as it achieves its effects. In addition, in the following drawings, identical or similar parts are denoted by the same or similar reference numerals. The drawings are schematic and do not necessarily correspond to actual dimensions or proportions. There may be parts in the drawings where the dimensional relationships or proportions differ from those of other drawings.
[0018] In this embodiment, the case in which the pelvic floor pressing device of the present invention is applied to a pelvic floor self-care device will be described as an example. Figure 1 is a perspective view of a pelvic floor self-care device 10 as an example of the pelvic floor pressing device of the present invention. Figure 2 is a front view of the pelvic floor self-care device 10, Figure 3 is a rear view of the pelvic floor self-care device 10, and Figure 4 is a right side view of the pelvic floor self-care device 10. The left side view is omitted because it appears symmetrically to the right side view.
[0019] Figure 5 is a schematic diagram of the deep layers of the pelvic floor of the human body. The pelvic floor muscles spread out like a hammock at the bottom of the pelvis and support the bladder, rectum, and other pelvic organs, including the uterus and ovaries in women, and the testicles and prostate in men. The figure shows the bones and soft tissues around the pelvis in a plan view from below the human body. The left side of the figure is the right pelvic floor, and the right side is the left pelvic floor. The soft tissues consist of skin, fat, fascia, and muscles (pelvic floor muscles). Figure 6 is an explanatory diagram showing the areas 41 to 44 of the pelvic floor that correspond to (pressure) multiple protrusions 11 to 14.
[0020] The pelvic floor self-care device 10, as an example of a pelvic floor pressing device of the present invention, is a palm-sized device used by the user under the pelvic floor. It comprises a plurality of raised parts 11 and 12 corresponding to the areas 41 and 42 surrounded by the left ischial ramus 33, left ischial tuberosity 34, left sacrotuberous ligament 35, anus 31, and coccyx 32 on the user's left pelvic floor, and a plurality of raised parts 13 and 14 corresponding to the areas 43 and 44 surrounded by the right ischial ramus 36, right ischial tuberosity 37, right sacrotuberous ligament 38, anus 31, and coccyx 32 on the user's right pelvic floor. The device is placed on a seat surface S, and it is essential that when the user sits on the device, each of the raised parts 11 to 14 presses against the respective areas 41 to 44 of the left and right pelvic floors.
[0021] The user places the pelvic floor self-care device 10 on a seating surface S, such as a chair or the floor, sits on it, and uses their body weight to apply pressure to the pelvic floor. When the user sits on the pelvic floor self-care device 10, the multiple raised parts 11 to 14 press from below against the left and right regions 41 to 44 of the user's pelvic floor, which are surrounded by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx. This is configured to loosen the muscles in that area.
[0022] Of the raised portions 11 to 14, raised portions 11 and 12 correspond to the user's left pelvic floor, and raised portions 13 and 14 correspond to the user's right pelvic floor. The areas 41 to 44 that are corresponding to (pressed by) the multiple raised portions 11 to 14 are located on the left and right sides, with the anus 31 and coccyx 32 as the center. The pelvic floor areas 41 to 44 contain soft tissues (skin, fat, fascia, muscles) including the pelvic floor, such as the levator ani muscle (pubococcygeus muscle, iliococcygeus muscle, puborectalis muscle). In addition, the intermediate and superficial layers (not shown) corresponding to the pelvic floor areas 41 to 44 contain soft tissues (skin, fat, fascia, muscles) including the pelvic floor, such as the superficial transverse perineal muscle and the deep transverse perineal muscle. These areas 41 to 44 are areas where massaging can improve urinary incontinence.
[0023] The prominence 11 corresponding to the user's left pelvic floor corresponds to the area enclosed by the left ischial tuberosity 34, the left sacrotuberous ligament 35, the anus 31, and the coccyx 32 of the user's left pelvic floor (area 41 shown by the diagonal lines in Figure 6). Hereinafter, this will be referred to as the first left prominence 11. The prominence 12 corresponds to the area between the left ischial ramus 33 of the user's left pelvic floor and the anus 31 (area 42 shown by the diagonal lines in Figure 6). Hereinafter, this will be referred to as the second left prominence 12. The second left prominence 12 is smaller than the first left prominence 11.
[0024] The prominence 13 corresponding to the user's right pelvic floor corresponds to the area enclosed by the right ischial tuberosity 37, the right sacrotuberous ligament 38, the anus 31, and the coccyx 32 of the user's right pelvic floor (area 43 shown by the diagonal lines in Figure 6). Hereinafter, this will be referred to as the first right prominence 13. The prominence 14 corresponds to the area between the right ischial ramus 36 of the right pelvic floor and the anus 31 (area 44 shown by the diagonal lines in Figure 6). Hereinafter, this will be referred to as the second right prominence 14. The second right prominence 14 is smaller than the first right prominence 13.
[0025] Furthermore, the bottom surface of the pelvic floor self-care device 10, which is the side that rests on the seat S, is formed in a convex shape in the front-to-back direction of the user when the user sits on the device 10. This guides the movement of the pelvis in anterior tilt (tilting forward) and posterior tilt (tilting backward), allowing the user to naturally apply appropriate pressure to the left and right regions 41 to 44 and massage them.
[0026] The pelvic floor self-care device 10 is designed so that when in use, each of the raised parts 11 to 14 fits within the pelvic floor region 41 to 44. This is because pain may occur if each of the raised parts 11 to 14 comes into contact with a bone, such as the ischium. Specifically, the distance L1 between the peaks of the first left raised part 11 and the first right raised part 13 of the pelvic floor self-care device 10 is preferably 48 mm to 52 mm. The distance L2 between the peaks of the second left raised part 12 and the second right raised part 14 is preferably 23 mm to 27 mm.
[0027] Furthermore, the distance L3 between the apex of the first left protrusion 11 and the second left protrusion 12, and between the apex of the first right protrusion 13 and the second right protrusion 14, is preferably 53 mm to 57 mm. The pelvic floor self-care device 10 body preferably has a distance L4 of 33 mm to 37 mm at its narrowest part, a distance L5 of 88 mm to 92 mm at its widest part, and a height L6 of 57 mm to 61 mm.
[0028] Although the degree of pelvic opening and size differ between men and women, the components and arrangement of bones and soft tissues are generally the same, so the above size can be used by both men and women. However, the size of the pelvic floor self-care device 10 is not limited to the above size. The pelvic floor self-care device 10 can be made of a material that has sufficient strength to not substantially change shape when weight is applied. For example, it can be made of a resin material with appropriate hardness.
[0029] Furthermore, the pelvic floor self-care device 10 of this embodiment includes a function to detect pressure applied to the soft tissues of the pelvic floor and a vibration stimulation application function to apply vibration stimulation to the soft tissues of the pelvic floor. Figure 7 is a schematic diagram showing the internal structure of the pelvic floor self-care device 10. The pelvic floor self-care device 10 is equipped with a pressure sensor 71 inside the first left protrusion 11 for detecting the pressure applied to the soft tissue region 41 located at the left pelvic floor by the first left protrusion 11. It is also equipped with a pressure sensor 71 inside the first right protrusion 13 for detecting the pressure applied to the soft tissue region 43 located at the right pelvic floor by the first right protrusion 13.
[0030] Furthermore, the pelvic floor self-care device 10 is equipped with vibrating bodies 72 that apply vibrational stimulation to the soft tissues of the pelvic floor, located inside the first left protrusion 11 and the second left protrusion 12, and inside the first right protrusion 13 and the second right protrusion 14.
[0031] Figure 7 is a schematic diagram illustrating the internal structure of the pelvic floor self-care device 10 as seen from the right side, showing the pressure sensor 71 located inside the first left protrusion 11 and the vibrating body 72 located inside the first left protrusion 11 and the second left protrusion 12. A schematic diagram illustrating the internal structure of the pelvic floor self-care device 10 as seen from the left side is omitted from the illustration, and the pressure sensor 71 located inside the first right protrusion 13 and the vibrating body 72 located inside the first right protrusion 13 and the second right protrusion 14 are omitted from the illustration.
[0032] Figure 8 is a block diagram showing the electrical configuration of the pelvic floor self-care device 10. Inside the pelvic floor self-care device 10 are a control unit 73 that receives a detection signal detected by a pressure sensor 71, generates notification information indicating the pressure applied to the soft tissue of the pelvic floor based on the detection signal, and transmits it to a communication unit 75; a vibration motor 74 that vibrates a vibrating body 72 according to a vibration control signal from the control unit 73; a communication unit 75 for communicating with external devices 90 such as smartphones via various communication networks; and a battery 76 that supplies power to each part of the pelvic floor self-care device 10. Each component is interconnected via a bus. The pelvic floor self-care device 10 is connected to an external device 90 such as a smartphone operated by the user via the communication unit 75, for example, by wireless communication such as short-range communication or other communication means and various networks.
[0033] The control unit 73 includes a CPU, ROM, RAM, etc. When the user operates the external device 90 to input and instruct operation information to the pelvic floor self-care device 10, the instructed operation information is transmitted to the pelvic floor self-care device 10. When the control unit 73 receives the operation information via the communication unit 75, it reads the program corresponding to the operation information from the program stored in the ROM and performs calculation processing, and each component is controlled based on this processing.
[0034] The control unit 73 functions as a communication means of the present invention together with the communication unit 75. Based on the detection signal received from the pressure sensor 71, the control unit 73 generates pressure display control information as an example of pressure notification information for displaying (notifying) the pressure applied to the soft tissues of the pelvic floor, and transmits it to the external device 90 via the communication unit 75. The external device 90 displays the pressure information on the display screen according to the received pressure display control information.
[0035] Pressure information on the soft tissues of the pelvic floor may be displayed quantitatively using numerical values, or it may be configured to be displayed using specific colors for easy intuitive understanding. For example, it may be configured to display the pressure in predetermined colors (dark red for strong pressure, light red for medium pressure, blue for weak pressure, etc.) according to the strength of the pressure. Alternatively, it may be displayed using illustrations such as shapes or message text corresponding to the strength of the pressure. Furthermore, an illustration of the pelvic floor may be displayed, and based on the detection signals received from each pressure sensor 71, pressure information may be displayed on the areas 41 and 43 corresponding to each pressure sensor 71 in the pelvic floor depicted in the illustration. This makes it easy to understand whether the appropriate pressure is being applied to the target area.
[0036] Furthermore, the control unit 73 functions together with the vibrating body 72 and the vibration motor 74 as a vibration stimulation application means of the present invention, applying vibration stimulation to the right and left pelvic floors. The control unit 73 generates a vibration control signal according to the received operation information and transmits it to the vibration motor 74. The vibration motor 74 vibrates the vibrating body 72 according to the vibration control signal received from the control unit 73. The vibrations generated by the vibrating body 72 vibrate each of the raised parts 11 to 14 of the pelvic floor self-care device 10, effectively applying vibration stimulation to the pelvic floor regions 41 to 44. This makes it possible to increase muscle activity in the pelvic floor.
[0037] For example, when a user operates the external device 90 to instruct the pelvic floor self-care device 10 to turn the vibration of the vibrating body 72 on or off as operation information, the control unit 73 generates a corresponding vibration control signal. The control unit 73 then transmits the generated vibration control signal to the vibration motor 74. The vibration motor 74 turns the vibration of the vibrating body 72 on or off according to the vibration control signal received from the control unit 73.
[0038] Furthermore, for example, if a user operates the external device 90 to input vibration speed and vibration intensity of the vibrating body 72 as operation information to the pelvic floor self-care device 10, the control unit 73 generates a vibration control signal according to the operation information. The control unit 73 then transmits the generated vibration control signal to the vibration motor 74. The vibration motor 74 can adjust the vibration speed and vibration intensity by vibrating the vibrating body 72 according to the vibration control signal received from the control unit 73.
[0039] Furthermore, the pelvic floor self-care device 10 may be equipped with a rotary knob for controlling the on / off switch of vibration, vibration speed, and vibration intensity. When the user operates the rotary knob, the control unit 73 receives instructions as operation information. The control unit 73 then generates a vibration control signal according to the operation information and adjusts the vibration speed and vibration intensity of the vibrating body 72.
[0040] As described above, with the pelvic floor self-care device 10, as shown in Figure 9, when the user sits on the pelvic floor self-care device 10 placed on the seat S and applies their weight, the multiple raised parts 11 to 14 apply downward pressure to the left and right regions 41 to 44 of the user's pelvic floor, which are surrounded by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx. This effectively relaxes the regions 41 to 44 and prevents urinary incontinence.
[0041] Furthermore, its compact size, which fits in the palm of your hand, makes it not only easy to carry but also allows for discreet use without being noticed, making it easy to use in various locations and maintain consistent use. In addition, the base of the pelvic floor self-care device 10 is convex in the front-to-back direction, allowing for natural anterior and posterior tilting movements in line with pelvic function, thereby improving the function of the pelvic floor muscles.
[0042] Furthermore, since the pelvic floor self-care device 10 is equipped with a pressure sensor 71 and the like inside, it is configured to detect the pressure applied to the soft tissues in the regions 41 and 43 of the pelvic floor and display (notify) it as pressure information. Thus, one can easily grasp the pressure applied to the soft tissues of the pelvic floor by oneself. Also, since the pelvic floor self-care device 10 is equipped with vibration stimulation addition means inside, vibration stimulation can be effectively applied to the soft tissues in the regions 41 to 44 of the left and right pelvic floors. The pelvic floor muscles included in the soft tissues can be exercised. By the operation of the user, the on / off control of the vibration, the vibration speed, and the vibration intensity can be adjusted. So, so-called muscle strength training of the pelvic floor muscles (exercising and relaxing the pelvic floor muscles) can be easily performed by oneself.
[0043] Note that the number and position of the pressure sensors 71 are not limited to the number and position described using FIG. 7. Any position and number that can detect the pressure in the regions 41 and 43 are acceptable. Also, the number and position of the vibrating bodies 72 are not limited to the number and position shown in FIG. 7. For example, it may be near the center inside the device or on the bottom surface side of the device. As long as vibration stimulation can be applied to the soft tissues in the regions 41 to 44 of the left and right pelvic floors.
[0044] Furthermore, the control unit 73 may be configured to function as the muscle hardness information acquisition means of the present invention. The control unit 73 calculates a numerical value corresponding to the muscle hardness of the pelvic floor muscles included in the soft tissues of the pelvic floor based on the detection signal detected by the pressure sensor 71.
[0045] Any method may be used for calculating the muscle hardness. For example, the value of the detection signal from the pressure sensor 71 is converted into the value of the pushing force reaction by the pelvic floor muscles included in the soft tissues of the corresponding regions 41 and 43 of the pelvic floor and calculated as a numerical value corresponding to the muscle hardness. The calculated numerical value is acquired as muscle hardness information. At this time, appropriate adjustment is made in consideration of the reaction force of the resin constituting the main body of the pelvic floor self-care device 10.
[0046] The control unit 73 functions as the communication means of the present invention together with the communication unit 75, and generates hardness display control information as an example of hardness information for displaying (notifying) the muscle hardness of the pelvic floor muscles included in the soft tissue of the pelvic floor based on the acquired muscle hardness information. Then, the generated hardness display control information is transmitted to the external device 90 via the communication unit 75. The external device 90 displays the hardness information on the display screen according to the received hardness display control information.
[0047] The muscle hardness information of the pelvic floor muscles included in the soft tissue of the pelvic floor may be quantitatively displayed by numerical values or the like, or may be displayed in a specific color or the like so as to be easily understood intuitively. Since the display method of the muscle hardness information is the same as the display method of the pressure information described above, a detailed description thereof will be omitted. The muscle hardness information may be displayed so that it can be intuitively understood whether it is within the recommended muscle hardness range, for example, green when it is within a predetermined allowable range and red when it is not within the allowable range.
[0048] In this way, since the pressure applied to the soft tissue in the regions 41 and 43 of the pelvic floor is detected, the muscle hardness is acquired based on the detection signal, and it is configured to be able to display (notify) as muscle hardness information, it is possible to easily grasp the muscle hardness of the pelvic floor muscles included in the soft tissue of the pelvic floor by oneself.
[0049] Although the pressure display control information and the hardness display control information have been described as examples, the present invention is not limited thereto. For example, it may be notified by voice. In this case, voice control information is used as pressure information or hardness information, the control unit 73 generates voice control information for notifying a voice corresponding to the pressure or the hardness, and the external device 90 receives this and performs voice notification from a speaker or the like. For example, it may be notified by a voice corresponding to the magnitude of the pressure applied to the pelvic floor so as to be easily understood intuitively. Also, when the muscle hardness is not within a predetermined allowable range, it may be notified by a warning sound or the like. Or, it may be notified by various sounds (for example, pitch height, etc.) corresponding to the pressure or the hardness.
[0050] Furthermore, the control unit 73 may be configured to generate vibration control signals according to the degree of muscle stiffness indicated by the stiffness information. For example, the vibration speed and vibration intensity of the vibrating body 72 may be reduced as the muscle stiffness indicated by the muscle stiffness information increases (the stiffer the muscle is). The vibration motor 74 changes the vibration of the vibrating body 72 according to the vibration control signals received from the control unit 73. This makes it possible to apply vibration stimulation appropriate to the muscle stiffness of the pelvic floor muscles. This is because a lower vibration speed has a greater relaxation effect, while a higher vibration speed is more effective in strengthening muscles.
[0051] The scope of application of the present invention is not limited to the embodiments described above. The present invention can be broadly applied to pelvic floor pressure devices that can apply pressure from below to the left and right regions of the pelvic floor, which are surrounded by the ischial ramus, ischial tuberosity, sacrotuberous ligament, anus, and coccyx.
