Description

[Technical field]

[0001] The present invention relates to a fascia release device that applies force to the skin by pressing it against the skin and moving it back and forth. [Background technology]

[0002] When fascia adheres to surrounding tissues such as the skin, the flow of blood and lymph is impeded, causing physical discomfort. A method of stimulating the skin called "fascial release" is known as a method for improving fascial adhesions, and tools that stimulate the skin for fascial release have also been developed.

[0003] A conventional fascia release tool is known that removes adhesions between the skin and fascia by pressing and moving an uninterrupted continuous surface against the skin (see Patent Document 1). Conventional fascia release tools such as those described in Patent Document 1 are made of a material with a sufficiently large coefficient of friction, and are used by pressing a flat surface against the skin and applying a rubbing motion.

[0004] Fig. 5 is a schematic diagram showing a conventional fascia release tool being pressed against the skin and moved. When a conventional fascia release tool 90 is held in the hand H and pressed against the skin S and moved, the entire flat surface of the fascia release tool 90 adheres to the skin S, so as shown in Fig. 5, force is concentrated near the tip in the direction of movement of the tool, while other parts are lifted up and separated from the skin S. Therefore, there is a problem that only the tip in the direction of movement of the fascia release tool 90 applies force locally to the skin S, but adhesion between the skin and fascia cannot be eliminated for other parts.

[0017] Next, an embodiment of a fascia release tool to which the present invention is applied will be described with reference to the drawings. Note that the embodiment described below is a preferred embodiment of the present invention, and therefore various technically preferable limitations are attached, but the scope of the present invention is not limited to these aspects unless otherwise specified in the following description to the effect that the present invention is limited.

[0018] First embodiment A fascia release tool according to a first embodiment of the present invention will be described with reference to Figures 1 to 3. Figure 1 is a perspective view showing the fascia release tool according to the first embodiment of the present invention. Figure 2 shows the fascia release tool according to the first embodiment of the present invention, where (a) is a front view seen from the front, (b) is a right side view, (c) is a cross-sectional view showing cross section AA of (b), and (d) is an enlarged view showing a portion B of (b). Figure 3 is a schematic diagram showing the state in which the fascia release tool according to the first embodiment of the present invention is in use.

[0019] First, the specific configuration of the fascia release tool 1 according to this embodiment will be described with reference to Figs. 1 and 2. The fascia release tool 1 includes a planar substrate 11 that extends in the front-rear and left-right directions, and multiple protrusions 12, 12 protruding downward from the substrate 11. The substrate 11 is formed in a rectangular shape when viewed from above. The protrusions 12 each extend linearly in the left-right direction and are arranged in parallel. The fascia release tool 1 also includes a rib 13 that protrudes upward from the substrate 11, and the rib 13 extends linearly in the front-rear direction. The fascia release tool 1 is integrally molded from an elastomer as a whole, and the substrate 11, the protrusions 12, and the rib 13 all have elasticity. Any elastomer can be selected as the material for the fascia release tool 1, but silicone rubber is preferably used.

[0020] As shown in Fig. 2(b), when the fascia release tool 1 is viewed from left to right, the protrusions 12 are formed in a rectangular shape and extend linearly in the left-right direction in a constant cross section. That is, when viewed in a cross section perpendicular to the left-right direction, the protrusions 12 are rectangular. The protrusions 12 are also arranged at equal intervals in the front-rear direction, and grooves are formed between the protrusions 12. That is, as shown in Fig. 2(d), a groove G is formed between the protrusions 12 by the bottom surface 11b of the substrate 11 and the wall surfaces 12a, 12a of the opposing protrusions 12. The corners formed by the bottom surface 11b and the wall surfaces 12a are rounded.

[0021] As shown in FIG. 2(b), the rib 13 is trapezoidal when the fascia release tool 1 is viewed from left to right. In the cross-sectional view of the cross section AA in FIG. 2(b), the fascia release tool 1 has the rib 13, which is a vertically long rectangle, protruding upward from the upper surface 11a of the substrate 11, which is a horizontally long rectangle, as shown in FIG. 2(c), and thus has an inverted T-shape as a whole. By connecting the rib 13 to the substrate 11, the second moment of area becomes larger than that of the substrate 11 alone, that is, a higher bending rigidity is obtained than that of the substrate 11 alone. The height of the rib 13 can be set arbitrarily, but it is preferable that the rib 13 is high enough to be held between the thumb and index finger of a human hand. As shown in FIGS. 1 and 2, the shape of the fascia release tool 1 is symmetrical left to right and front to back.

[0022] Next, a method of using the fascia release tool 1 according to this embodiment will be described with reference to FIG. 3. When using the fascia release tool 1, the rib 13 is pinched from the left and right with the bent index finger and thumb of the hand H, and the lower side of the index finger and thumb of the hand H is placed against the upper surface 11a of the base plate 11 to hold the fascia release tool 1. Then, the protrusion 12 is pressed against the skin S, and the fascia release tool 1 is moved back and forth. At this time, the fascia release tool 1 is firmly pressed from above so that the force reaches the fascia deep inside the skin S. All of the multiple protrusions 12,...,12 are in contact with the skin S. When moving the fascia release tool 1 back and forth, the protrusions 12 are moved to a degree that does not exceed the friction limit and does not slide against the surface of the skin S.

[0023] FIG. 3 shows the state in which the fascia release tool 1 is pressed against the skin S and moved forward to the extent that it does not slide beyond the limit of friction. At this time, the hand H applies a forward force to the fascia release tool 1 via the rib 13. In response to this, the skin S applies a backward force to the fascia release tool 1 via the multiple protrusions 12,...,12. Due to the backward force applied by the skin S to the protrusions 12, the protrusions 12 are deformed by bending moment and shear force, so that the front corners 12b,...,12b of each of the protrusions 12 move to dig into the skin S, and the rear corners 12c,...,12c of each of the protrusions 12 move to move away from the skin S. This allows the protrusions 12 to firmly grip the skin S. In addition, since all of the protrusions 12 are in contact with the skin S, the fascia release tool 1 applies force to a wide area of ​​the skin S.

[0024] In the state shown in Fig. 3, a forward force acts on the rib 13 and a backward force acts on the protrusions 12, so that when the entire fascia release tool 1 is viewed as a beam in the side view shown in Fig. 2(b), a bending moment acts that makes it convex upward or convex downward. However, as mentioned above, since the rib 13 protrudes upward from the base plate 11, the second moment of area is large and the bending rigidity is high, so the amount of bending deformation of the entire fascia release tool 1 as a beam is kept small. Therefore, it is possible to maintain a state in which all the protrusions 12 are in contact with the skin S.

[0025] Although Figure 3 shows the fascia release tool 1 being moved forward, the deformation of the fascia release tool 1 when it is moved backward is symmetrical to that in Figure 3, with the rear corners 12c, ..., 12c of each protrusion 12 moving to dig into the skin S, and the front corners 12b, ..., 12b of each protrusion 12 moving to move away from the skin S.

[0026] By pressing the fascia release tool 1 against the skin S and moving it back and forth to the extent that it does not slide against the surface of the skin S, the protrusions 12 grip the skin S and apply force deep into it, improving adhesion between the skin S and the fascia.

[0027] Second Embodiment Next, the configuration of a fascia release tool according to a second embodiment of the present invention will be described with reference to Fig. 4. Fig. 4 is a front view of the fascia release tool according to the second embodiment of the present invention as seen from the front.

[0028] The difference between the fascia release tool 2 according to this embodiment and the fascia release tool 1 according to the first embodiment is the shape of the rib. That is, as shown in FIG. 4, the rib 14 of the fascia release tool 2 is formed as a trapezoid with the upper base shorter than the lower base when viewed from the front of the fascia release tool 2, and extends linearly in the front-rear direction in a constant cross section. That is, the width of the rib 14 is formed to become narrower from bottom to top in a cross section perpendicular to the front-rear direction. This configuration makes the rib 14 difficult to bend left and right. Therefore, it is easy to transmit force to the skin. Also, in the cross section corresponding to FIG. 2(b), the second moment of area is even larger than that of the first embodiment, that is, even higher bending rigidity is obtained.

[0029] (Other embodiments) In the above-mentioned embodiment, the fascia release tools 1 and 2 are equipped with the ribs 13 and 14, respectively, but it is also possible to configure the fascia release tool without the ribs. Even in this case, the multiple protrusions 12 can come into contact with the skin and apply force to a wide area of ​​the skin.

[0030] In the above embodiment, the protrusions 12 are rectangular in cross section perpendicular to the left-right direction, but the shape is not limited to this and may be semicircular, for example. Even in this case, multiple protrusions 12 come into contact with the skin and can apply force to a wide area of ​​the skin.

[0031] In the above embodiment, the fascia release tools 1 and 2 are integrally made of elastomer, but instead of making all the components out of elastomer, it is also possible to make only the protrusion 12 out of an elastic material. Even in this case, when the protrusion is pressed against the skin and the fascia release tool is moved back and forth, bending moment and shear force act on the protrusion, and deformation similar to that shown in FIG. 4 occurs on the protrusion. Therefore, the protrusion can grip the skin and apply force deep into the skin. In addition, using a material with a large friction coefficient as the material for the protrusion is preferable because it makes it possible to apply a large force to the skin in the back and forth direction.
