[Effects of the Invention]

[0010] According to this invention, it is possible to provide a medical sheet for joints that can restore the function of the joints. [Brief explanation of the drawing]

[0011] [Figure 1] This is an external view of the joint medical sheet of the present invention, shown from the side of the adhesive surface. [Figure 2] This is an external view showing the state of the joint medical sheet of the present invention when in use. [Modes for carrying out the invention]

[0012] The embodiments of this invention will be described below with reference to the drawings.

[0013] As shown in Figures 1 and 2, in one embodiment of the present invention, the flexible joint medical sheet 1 has a water-containing adhesive layer 4 that is attached to the skin 3 of the joint 2 (joints below the neck). The adhesive layer 4 has a base portion 4a and a flap portion 4b. The flap portion 4b is partitioned so as to rotate relative to the base portion 4a by a central slit 4c provided in the center of the adhesive layer 4. As the adhesive layer 4 is attached to the skin 3 of the joint 2, the flap portion 4b rotates relative to the base portion 4a so as to follow the curved portion 3a (protruding portion or depression) of the skin 3, thereby enabling the base portion 4a to follow the portion of the skin 3 around the curved portion 3a.

[0014] According to the above configuration, as shown in Figure 2, the water-containing adhesive layer 4 of the joint medical sheet 1 can be attached to the skin 3 having a curved portion 3a of a joint 2 such as the knee, by the rotation of the flap portion 4b so as to conform to the surface shape of the skin 3, gently enveloping the joint 2 without compressing it. In this case, adhesive tape such as silicone tape may be used to further assist the adhesive force (adhesion) to the skin 3 due to the moisture of the adhesive layer 4 of the joint medical sheet 1. If the joint 2 is the knee, the curved portion 3a is the raised portion 3a1 (patella). By maintaining this state for a certain period of time, such as 10 minutes, the moisture and body temperature of the skin 3 and muscles of the joint 2 can be well maintained during that time. As a result, the muscles of the joint 2 can be relaxed, and if there is inflammation, the inflammation can be alleviated. It can also gently envelop the joint nerves and regulate the autonomic nervous system. By repeating such use over an appropriate period of time, the functional stability of the joint 2 can be improved, and the function of the joint 2 can be restored. Furthermore, it can enhance the self-healing power through nerve reconstruction. Therefore, it can be used before and after treatment, during post-treatment rehabilitation, during post-injury conditioning, and before and after high-intensity training, with the aim of preventing functional decline or improving function.

[0015] The adhesive layer 4 is rectangular in shape, defining the short axis and long axis directions. The outer peripheral edge 1a of the joint medical sheet 1 extends rectangularly along the outer peripheral edge 4d of the adhesive layer 4. The outer peripheral edge 1a of the rectangular joint medical sheet 1 may or may not coincide with the outer peripheral edge 4d of the rectangular adhesive layer 4. The central slit 4c is U-shaped, with one side in the short axis direction curved. The adhesive layer 4 has a pair of slits 5 on one side in the short axis direction, a pair of slits 6 on the other side in the short axis direction, a slit 7 on one side in the long axis direction, and a slit 8 on the other side in the long axis direction. The pair of slits 5 on one side in the short axis direction are provided on both sides of the central slit 4c in the long axis direction, and each extends from one end in the short axis direction to the other end in the short axis direction of the joint medical sheet 1. A pair of short-axis axial side slits 6 are provided on both sides of the central slit 4c in the long axis direction, and each extends from the other end in the short axis direction of the joint medical sheet 1 toward one side in the short axis direction. A long-axis side slit 7 is provided in the central part in the short axis direction and extends from the one end in the long axis direction of the joint medical sheet 1 toward the other side in the long axis direction. A long-axis side slit 8 is provided in the central part in the short axis direction and extends from the other end in the long axis direction of the joint medical sheet 1 toward one side in the long axis direction.

[0016] With the above configuration, as shown in Figure 2, since the adhesive layer 4 is rectangular in shape, when attaching the adhesive layer 4 to a joint 2 such as the knee, the adhesive layer 4 can be easily attached to wrap around the joint 2 by wrapping it around half a circumference or the like with the long axis of the adhesive layer 4 perpendicular to the long direction of the foot. At that time, the U-shaped central slit 4c makes it easier for the flap portion 4b to follow the curved portion 3a of the joint 2. Furthermore, the pair of short axis slits 5 on one side, the pair of short axis slits 6 on the other side, the long axis slit 7 on one side, and the long axis slit 8 provided on the outer edge 1a of the joint medical sheet 1 make it easier for the outer edge 4d of the adhesive layer 4 to follow the skin 3 around the joint 2 when attached to the joint 2. In other words, the outer edge 1a of the joint medical sheet 1 can be easily deformed to open or close these slits as appropriate, depending on the surface shape of the skin 3.

[0017] The medical sheet 1 for joints has no slits other than the central slit 4c, the pair of short-axis direction one-side slits 5, the pair of short-axis direction the other-side slits 6, the long-axis direction one-side slit 7, and the long-axis direction the other-side slit 8. According to the above configuration, since there are no unnecessary slits, the usability can be enhanced.

[0018] The U-shaped central slit 4c is composed of a pair of linear portions 4c1 facing each other in the long-axis direction and an arc-shaped curved portion 4c2 connecting the pair of linear portions 4c1.

[0019] When the joint 2 to be pasted is the knee, it is preferable that the length of the medical sheet 1 for joints in the short-axis direction is 12 to 30 cm and the length in the long-axis direction is 17 to 35 cm. More preferably, the length in the short-axis direction is 15 to 27 cm and the length in the long-axis direction is 20 to 32 cm. Even more preferably, the length in the short-axis direction is 18 to 24 cm and the length in the long-axis direction is 23 to 29 cm.

[0020] Also in this case, it is preferable that the U-shaped central slit 4c has a length in the short-axis direction of 1.5 to 7.5 cm (the length of the pair of linear portions 4c1 is 0.5 to 3.5 cm, and the length of the curved portion 4c2 is 1.0 to 4.0 cm) and a length in the long-axis direction of 3.0 to 9.0 cm. More preferably, the length in the short-axis direction is 2.5 to 6.5 cm (the length of the pair of linear portions 4c1 is 1.0 to 3.0 cm, and the length of the curved portion 4c2 is 1.5 to 3.5 cm), and the length in the long-axis direction is 4.0 to 8.0 cm. Even more preferably, the length in the short-axis direction is between 3.5 and 5.5 cm (the length of the pair of linear portions 4c1 is 1.5 to 2.5 cm, and the length of the curved portion 4c2 is 2.0 to 3.0 cm), and the length in the long-axis direction is 5.0 to 7.0 cm.

[0021] Also in this case, the lengths of the pair of short-axis direction one-side slits 5 and the pair of short-axis direction the other-side slits 6 in the short-axis direction are preferably 1.0 cm to 5.0 cm, more preferably 2.0 cm to 4.0 cm, and even more preferably 2.5 cm to 3.5 cm. [[ID=​​In this case, the pair of slits 5 on one side in the short axis direction and the pair of slits 6 on the other side in the short axis direction are preferably located 2.0 to 12.0 cm from the closer end in the long axis direction of the joint medical sheet 1, more preferably 4.0 to 10.0 cm, and even more preferably 6.0 to 8.0 cm.

[0023] In this case, the slit 7 on one side in the longitudinal direction and the slit 8 on the other side in the longitudinal direction are preferably 2.0 to 12.0 cm in length in the longitudinal direction, more preferably 4.0 to 10.0 cm, and even more preferably 6.0 to 8.0 cm.

[0024] The adhesive layer 4 has an adhesive surface 4e that is attached to the skin 3 of the joint 2. The adhesive layer 4 is made of a material that adheres to the skin due to the moisture it contains. Examples of such materials include cellulose-based materials (nonwoven fabric, biocellulose), hydrogel-based materials (polymer gels), and hydrocolloid-based materials. The joint medical sheet 1 may also have a base layer (not shown) laminated on the side of the adhesive layer 4 opposite to the adhesive surface 4e. The base layer may be water-containing.

[0025] The water-containing adhesive layer 4 (and base layer) may contain moisture from the time of distribution, or the user may add moisture to it when using it. Furthermore, the adhesive layer 4 (and base layer) may contain medicinal ingredients for the purpose of restoring joint function 2, etc. The medicinal ingredients may also have skin-beautifying effects. The medicinal ingredients may be present from the time of distribution, or the user may add moisture to them when using it.
