And a human body sits on a seat surface and a correction tool (refer to patent documents 1).

JP-A-10-313970

  The correction tool described above attempts to correct the posture of the human body from the outside of the human body, but cannot improve the posture by actively moving muscles inside the human body. In recent years, it has been considered that positive movement of muscles located in the human body, for example, the diaphragm, transverse abdominal muscles, multifidus muscles, spine standing muscles, etc., leads to improved posture. In particular, it is considered to positively move these muscles by pressing the pelvic floor muscles.

  However, pressing the pelvic floor muscle group is pressing the crotch with a finger or the like. About such a press, especially young women may feel strong resistance.

  An object of this invention is to provide the pelvic floor muscle group presser which presses a pelvic floor muscle group moderately.

  The present invention has at least a 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 ischies of the human body in the width direction with respect to the longitudinal direction, and the human body in the longitudinal direction The entire portion corresponding to the length between the pubic bone and the coccyx has a convex upper surface that curves outwardly from one end to the other end of the width in the longitudinal direction, and the longitudinal direction in the longitudinal direction of the human body. When the human body sits on the seating surface and straddles the convex upper surface, the convex upper surface faces the pubic bone and coccyx and presses the pelvic floor muscles. The present invention relates to a pelvic floor muscle group pressing tool.

  Moreover, it is preferable that the convex upper surface includes a lower surface that is curved outward from one end portion to the other end portion in the longitudinal direction, is configured by a flat surface, and has a positional relationship facing the convex upper surface.

  Moreover, it is preferable to provide a convex lower surface that curves outwardly from one end to the other end of the width in the longitudinal direction and has a positional relationship facing the convex upper surface.

  The maximum distance between the convex upper surface and the lower surface is preferably 30 mm to 60 mm, or the maximum distance between the convex upper surface and the convex lower surface is preferably 30 mm to 60 mm.

  Moreover, it is preferable to have the hardness of 10-20 by the value of the international rubber hardness (IRHD) according to JIS K6253.

  Here, for convenience of explanation, a direction from the convex lower surface 12 to the convex upper surface 11 of the pelvic floor muscle group pressing tool 1 described later is defined as an upward direction D11, and the opposite direction is defined as a downward direction D12. These are defined as a vertical direction D1. Also, the direction perpendicular to the vertical direction D1 and directed from the front side to the back side of the paper surface of FIG. 2 is defined as the front direction D21, the opposite direction is defined as the rear direction D22, and these are defined as the front-rear direction D2. Define. 2 is defined as a left direction D31, the opposite direction is defined as a right direction D32, and these are defined as a left and right direction D3.

As shown in FIGS. 1 to 2, the pelvic floor muscle group pressing tool 1 includes a convex upper surface 11, a convex lower surface 12, a left connection curved surface 13, a right connection curved surface 14, a front end surface 15, and a rear end surface. 16 and.
The convex upper surface 11 extends from one end to the other end of the width in the longitudinal direction D2 as the longitudinal direction of the pelvic floor muscle group pressing tool 1, that is, from the left end 101 to the right end 102 of the pelvic floor muscle group pressing tool 1. It curves in the upward direction D11 as outward. The shape of the curve is uniform from the front end face 15 to the rear end face 16 of the pelvic floor muscle group pressing tool 1. In other words, the entire portion of the pelvic floor muscle group pressing tool 1 corresponding to the length between the pubic bone and the coccyx of the human body H (see FIG. 2) in the longitudinal direction of the pelvic floor muscle group pressing tool 1. Has a convex upper surface 11. As shown in FIG. 1A, the convex upper surface 11 of the pelvic floor muscle group pressing tool 1 has a substantially semicircular shape with a radius of 22.5 mm when viewed from the front.

  The convex lower surface 12 is located on the downward direction D12 side of the convex upper surface 11 and has a positional relationship facing the convex upper surface 11. The convex lower surface 12 extends from one end to the other end of the width in the longitudinal direction D2 as the longitudinal direction of the pelvic floor muscle group pressing tool 1, that is, from the left end 101 to the right end 102 of the pelvic floor muscle group pressing tool 1. , Curving downward as outward. The shape of the curve is uniform from the front end face 15 to the rear end face 16 of the pelvic floor muscle group pressing tool 1. Therefore, as shown in FIG. 1A, the convex lower surface 12 of the pelvic floor muscle group pressing tool 1 has an arc shape with a radius of 30 mm when viewed from the front.

  The left end edge of the convex upper surface 11 and the left end edge of the convex lower surface 12 are connected by a left connection curved surface 13 that curves in the left direction D31. Similarly, the right end edge of the convex upper surface 11 and the right end edge of the convex lower surface 12 are connected by a right connection curved surface 14 that curves in the left direction D31. The left connection curved surface 13 and the right connection curved surface 14 each have a constant width of 4.5 mm from the front end surface 15 to the rear end surface 16 of the pelvic floor muscle group pressing tool 1 in the vertical direction D1. As shown in FIG. 1A, the left connecting curved surface 13 and the right connecting curved surface 14 have an arc shape with a radius of 8 mm when viewed from the front.

  The front end face 15 and the rear end face 16 have a mutually parallel positional relationship. Further, the front end face 15 and the rear end face 16 are orthogonal to the front-rear direction D2. Connection portions of the front end surface 15 and the rear end surface 16 with the convex upper surface 11, the convex lower surface 12, the left connection curved surface 13, and the right connection curved surface 14 have an R chamfered shape with a radius of about 5 mm.

  The length between the front end face 15 and the rear end face 16, that is, the length (full length) in the longitudinal direction of the pelvic floor muscle group pressing tool 1 is 207 mm. Therefore, the pelvic floor muscle group pressing tool 1 has a length (full length) longer than that between the pubic bone and the coccyx of the human body H in the longitudinal direction. The width in the left-right direction D3 is 45 mm. Therefore, the pelvic floor muscle group pressing tool 1 has a width shorter than the length between the pair of sciatic bones of the human body H in the left-right direction D3 as the width direction. Further, the maximum distance between the convex upper surface 11 and the convex lower surface 12 of the pelvic floor muscle group pressing tool 1, that is, the distance from the upper end to the lower end of the pelvic floor muscle group pressing tool 1 is preferably 30 mm to 60 mm. . In the first embodiment, the distance from the upper end to the lower end of the pelvic floor muscle group pressing tool 1 is 50 mm. In the case of a value smaller than 30 mm, the pressure on the pelvic floor muscle group is not sufficient. Further, when the value is larger than 60 mm, pain is felt in the vicinity of the pubic bone and the vicinity of the coccyx of the human body H.

The pelvic floor muscle group pressing tool 1 is made of urethane resin. Further, the pelvic floor muscle group pressing tool 1 has a hardness of 10 to 20 as an international rubber hardness (IRHD) value according to JIS K6253. The hardness of the pelvic floor muscle group pressing tool 1 according to the first embodiment is 12. If it is less than 10, it is too hard to feel pain in the vicinity of the pubic bone and the coccyx of the human body H. Moreover, when it exceeds 20, it is too soft and the press against the pelvic floor muscle group is not sufficient.
This hardness value is the center position of the pelvic floor muscle group pressing tool 1 in the front-rear direction D2 and the portion of the convex upper surface 11 corresponding to the center position in the left-right direction D3, “JIS” teclock durometer (( The measurement was performed by bringing a product of Tecroc Co., Ltd.) into contact with the convex upper surface 11 as a vertical positional relationship.

  The pelvic floor muscle group pressing tool 1 having the above-described configuration is used as follows. First, as shown in FIG. 2, the pelvic floor muscles are positioned on the seat surface S of a chair or the like in a positional relationship in which the longitudinal direction coincides with the longitudinal direction D2 of the human body H, that is, in the forward direction D21 and the backward direction D22. The pelvic floor muscle group pressing tool 1 is placed in a positional relationship in which the front direction D21 and the rear direction D22 of the group pressing tool 1 coincide. Next, the human body H sits on the seating surface S, and the convex upper surface 11 straddles the convex upper surface 11 of the pelvic floor muscle group pressing tool 1 in a positional relationship facing the pubic bone and the tailbone of the human body H, respectively.

At this time, the pelvic floor muscle group presses the pelvic floor muscle group pressing tool 1 by the weight of the upper body of the human body H sitting on the seat surface S and the pelvic floor muscle group pressing tool 1. At the same time, the gluteal and thigh muscles push the seat surface S.
On the other hand, the pelvic floor muscle group receives a reaction force from the pelvic floor muscle group pressing tool 1, and simultaneously, the gluteal and thigh muscles receive a reaction force from the seat surface S. The human body H tries to adjust the posture so as not to receive stimulation as much as possible near the pubic bone and the coccyx, and is pressed by the convex upper surface 11 of the pelvic floor muscle group pressing tool 1 as well as the gluteal and thigh muscles. The base muscle group and the so-called inner muscles around it (diaphragm, transverse abdominal muscle, multifidus muscle, spine standing muscle, etc.) are moved. These muscles are difficult to move unless touched by a finger or the like and are not conscious, but can be conscious and moved by pressing the pelvic floor muscle group with the pelvic floor muscle group pressing tool 1.

  That is, the pelvic floor muscle group pressing tool 1 has a length between the pubic bone and the coccyx of the human body H in the longitudinal direction (front-rear direction D2), and a pair of the human body H in the width direction with respect to the longitudinal direction (left-right direction D3). The entire portion corresponding to the length between the pubic bone and the coccyx of the human body H in the longitudinal direction is outward from one end to the other end of the width in the longitudinal direction. It has a convex upper surface 11 that curves toward the top. For this reason, the pelvic floor muscle group receives a reaction force from the convex upper surface 11 of the pelvic floor muscle group pressing tool 1, and the human body H adjusts the posture so as not to be stimulated by the pubic bone and the tailbone, and the pelvic floor muscle group And the so-called inner muscles (diaphragm, transverse abdominal muscle, multifidus, standing spine) can be moved. As a result, not only the posture is improved, but also, for example, urinary incontinence can be stopped, and the size of the waist can be reduced.

  Next, a pelvic floor muscle group pressing tool 1A according to a second embodiment of the present invention will be described with reference to FIGS. The external shape and hardness of the pelvic floor muscle group pressing tool 1A of the second embodiment are different from the external shape and hardness of the pelvic floor muscle group pressing tool 1 of the first embodiment. Since it is the same as that of the pelvic floor muscle group pressing tool 1 of 1st Embodiment except this, description is abbreviate | omitted about the same part.

The pelvic floor muscle group pressing tool 1A has a convex upper surface 11A, a lower surface 12A, a left connection plane 13A, a right connection plane 14A, a front end surface 15A, and a rear end surface 16A.
The convex upper surface 11A extends from one end to the other end of the width in the longitudinal direction D2 as the longitudinal direction of the pelvic floor muscle group pressing tool 1A, that is, from the left end 101A to the right end 102A of the pelvic floor muscle group pressing tool 1A. It curves in the upward direction D11 as outward. Further, the convex upper surface 11A is curved outward (upward direction D11) from one end portion to the other end portion in the longitudinal direction, that is, from the front end surface 15A to the rear end surface 16A in FIG. Therefore, the central portion in the left-right direction D3 and the central portion in the front-rear direction D2 of the pelvic floor muscle group pressing tool 1A protrudes in the most upward direction D11.

In other words, the entire portion of the pelvic floor muscle group pressing tool 1A corresponding to the length between the pubic bone and the tailbone of the human body H in the longitudinal direction of the pelvic floor muscle group pressing tool 1A is as described above. It has a convex upper surface 11A. As shown in FIG. 3, the pelvic floor muscle group pressing tool 1A has a substantially semicircular shape with a radius of 22.5 mm when viewed from the front.
The lower surface 12A has a positional relationship facing the convex upper surface 11A. The lower surface 12A is a flat surface.

The left end edge of the convex upper surface 11A and the left end edge of the lower surface 12A are connected by a flat left connection plane 13A. Similarly, the right end edge of the convex upper surface 11A and the right end edge of the lower surface 12A are connected by a flat right connection plane 14A. The virtual extension plane of the left connection plane 13A and the virtual extension plane of the right connection plane 14A have a positional relationship that intersects at an angle of 2 ° at a position closer to the lower direction D12 than the lower surface 12A.
The front end face 15A and the rear end face 16A have a positional relationship parallel to each other. Further, the front end face 15A and the rear end face 16A are orthogonal to the front-rear direction D2. A connecting portion between the front end face 15A and the rear end face 16A and the convex upper face 11A, lower face 12A, left connecting plane 13A, and right connecting plane 14A has a chamfered shape with a radius of about 5 mm.

  The length between the front end face 15A and the rear end face 16A, that is, the length in the longitudinal direction of the pelvic floor muscle group pressing tool 1A is preferably 180 mm or more. In the pelvic floor muscle group pressing tool 1A according to the second embodiment, 207 mm. Therefore, the pelvic floor muscle group pressing tool 1A has a length (full length) longer than that between the pubic bone and the coccyx of the human body H in the longitudinal direction. The width in the left-right direction D3 is 45 mm. Accordingly, the pelvic floor muscle group pressing tool 1A has a width shorter than the length between the pair of sciatic bones of the human body H in the left-right direction D3 as the width direction. The maximum distance between the convex upper surface 11A and the lower surface 12A of the pelvic floor muscle group pressing tool 1A, that is, the distance from the upper end to the lower end of the pelvic floor muscle group pressing tool 1A is preferably 30 to 60 mm. In the second embodiment, the distance from the upper end to the lower end of the pelvic floor muscle group pressing tool 1A is 50 mm. In the case of a value smaller than 30 mm, the pressure on the pelvic floor muscle group is not sufficient. Further, when the value is larger than 60 mm, pain is felt in the vicinity of the pubic bone and the vicinity of the coccyx of the human body H.

  Further, the pelvic floor muscle group pressing tool 1A has a hardness of 10 to 20 in terms of international rubber hardness (IRHD) in accordance with JIS K6253. The hardness of the pelvic floor muscle group pressing tool 1A according to the second embodiment is 14. If it is less than 10, it is too hard to feel pain in the vicinity of the pubic bone and the coccyx of the human body H. Moreover, when it exceeds 20, it is too soft and the press against the pelvic floor muscle group is not sufficient. The method for measuring hardness is the same as the method for measuring hardness in the first embodiment.

The pelvic floor muscle group pressing tool 1A configured as described above is used in the same manner as the pelvic floor muscle group pressing tool 1 according to the first embodiment. At that time, the convex upper surface 11A is curved outward (upward) from one end portion (front end surface 15A) to the other end portion (rear end surface 16A) in the longitudinal direction. When receiving a reaction force from the pelvic floor muscle group pressing tool 1A, the human body H can reduce the stimulation received in the vicinity of the pubic bone and the vicinity of the coccyx.
Therefore, even when the user feels painful when using the pelvic floor muscle group pressing device 1 according to the first embodiment, when using the pelvic floor muscle group pressing device 1 according to the second embodiment, The pelvic floor muscles can be pressed comfortably without feeling pain.

  Next, the maximum distance between the convex upper surface 11A and the lower surface 12A of the pelvic floor muscle group pressing tool was changed, and a test for confirming the effect of the present invention was performed. In the test, the pelvic floor muscle group pressing tool 1 </ b> A according to the second embodiment was designated as Invention 2. Further, the maximum distance in the vertical direction D1 is 20 mm, 25 mm, 35 mm, 55 mm, 65 mm, and 70 mm, and the other configurations are the same as those of the pelvic floor muscle group pressing tool 1A according to the second embodiment, respectively. Comparative product 2, invention product 1, invention product 3, comparison product 3 and comparison product 4. And 50 subjects used the pelvic floor muscle group pressing tool, and examined the presence or absence of pain near the pubic bone and the coccyx and the degree of pressing of the pelvic floor muscle group.

Specifically, among the 50 subjects, the number of persons with particularly strong pain near the pubic bone and tailbone was counted as “pain”. In addition, among the 50 subjects, the number of persons who felt that the degree of pressing of the pelvic floor muscle group was sufficient was counted as “sufficient pressing”. The test results are as shown in Table 1 below.

  As shown in Table 1, the number of people who felt strong pain was small in Invention 1, Invention 2, and Invention 3, but in Comparative Product 3 and Comparative Product 4, most people suffered strong pain. I feel. On the other hand, in Inventive Product 1, Inventive Product 2, and Inventive Product 3, there were many injured persons who felt that the degree of pressing was sufficient, but in Comparative Product 1 and Comparative Product 2, most of the injured persons I feel that the degree of pressing is unsatisfactory. From this result, it can be seen that the inventions in which the maximum distance between the convex upper surface and the lower surface is 30 mm to 60 mm do not feel pain strongly, and the degree of pressing of the pelvic floor muscle group is sufficient.

  Moreover, the test which confirms the effect of this invention was done by changing the hardness of a pelvic floor muscle group press. In the test, the pelvic floor muscle group pressing tool 1 </ b> A according to the second embodiment was designated as Invention 2. Further, the hardness (IRHD) values are 26, 21, 20, 11, 7, and 9, and the other configurations are the same as those of the pelvic floor muscle group pressing tool 1A according to the second embodiment, respectively. Comparative product 2, invention product 1, invention product 3, comparison product 3 and comparison product 4. And 50 subjects used the pelvic floor muscle group pressing tool, and examined the presence or absence of pain near the pubic bone and the coccyx and the degree of pressing of the pelvic floor muscle group.

Specifically, among the 50 subjects, the number of persons with particularly strong pain near the pubic bone and tailbone was counted as “pain”. In addition, among the 50 subjects, the number of persons who felt that the degree of pressing of the pelvic floor muscle group was sufficient was counted as “sufficient pressing”. The test results are as shown in Table 2 below.

  As shown in Table 1, the number of people who felt strong pain was small in Invention 1, Invention 2, and Invention 3, but in Comparative Product 3 and Comparative Product 4, most people suffered strong pain. I feel. On the other hand, as shown in Table 1, in invention 1, invention 2, and invention 3, there were many injured persons who felt that the degree of pressing was sufficient, but in comparison 1 and comparison 2, Most people feel that the degree of pressure is unsatisfactory. From this result, none of the invention products having an international rubber hardness (IRHD) value of 10 to 20 in accordance with JIS K6253 feel strongly painful and the degree of pressing of the pelvic floor muscles is sufficient. I understand that there is.

In addition, 100 subjects were allowed to use the pelvic floor muscle group pressing device 1A according to the second embodiment twice a day for about 2 minutes, for 7 days.
