Description

Technical Field

[0001] The present invention relates to a pad for an orthopedic aid, and the pad substrate has at least two pairs of arranged elastic regions.

[0002] In addition, the present invention also relates to an orthopedic aid, in particular an orthosis or a bandage including at least one such pad. Background Art

[0003] Pads for various preventive and therapeutic uses are known in the prior art, for example, refer to patent publication documents DE2722563C2, EP0598291A1, and EP0600218A2.

[0004] Many patients with knee osteoarthritis suffer from patellar arthritis, which is manifested as pain when the patella is compressed and the sliding joint surface is involved. Even moderate but continuous pressure can cause pain, such as when wearing tight jeans. The main muscle groups around the large joints of such patients often show painful sclerosis and shortening, and painful trigger point sclerosis often forms on the muscle surface. For knee osteoarthritis, it is necessary to relax the tissues, joint spaces, and the area behind the patella. For this purpose, special targeted massage techniques are used in physical therapy. Additionally or alternatively, bandages and orthoses with pads are used. When the muscles are under pressure, a massage effect is generated through the protrusions as convex pressing members (such as convex points), releasing contractures and inducing muscle sensorimotor responses. Pads with such protrusions (especially massage convex points) are applicable not only to the patella but also to other body parts, for example, refer to patent documents DE4238610A1 and DE102012105626A1.

[0005] These convex points act on muscles, such as the "vastus medialis" in the sensorimotor sense. In the resting state, the pressure effect / compression only comes from the fabric tension of the bandage or orthosis. When the muscle is tense (i.e., contracting), the pressure increases due to the increase in muscle volume, thereby triggering an analgesic sensorimotor response. Even during exercise, such as when walking with the knees and hips flexed, the convex points generate increased pressure under the load.

[0006] The defect of the pads in the prior art (such as patellar pads) is that the pads slide during movement. For example, due to the tensile resistance of the silicone patellar pad, when the patellar pad flexes, it will exert a significant distal pulling force on the upper part of the bandage, which will cause a sliding tendency and cause inappropriate compression on the patella of arthritis patients. At the same time, the distal pulling force will reduce the vertical therapeutically effective convex point pressure, partly because the bending of the convex points will cause a significant weakening of the sensorimotor response of the vastus medialis. Summary of the Invention

[0007] In view of the above, the object of the present invention is to provide a pad that can not only exert a good massage function but also avoid the sliding of the pad during movement.

[0008] Another object of the present invention is to provide a pressure pad that not only maintains excellent massage functions and effects, reduces structural costs, but also ensures a comfortable feeling during long-term wearing.

[0009] To solve the above technical problems, the present invention proposes the pressure pad described in independent claim 1.

[0010] In the technical solution of the present invention, a pressure pad includes a pressure pad base body, and the pressure pad base body has a front side and a rear side. Among them, at least one convex portion is provided on the front side of the pressure pad base body. It is characterized in that the pressure pad base body has at least two pair-arranged elastic regions, and these two elastic regions divide the pressure pad base body into a first pressure pad base body region and a second pressure pad base body region. Among them, at least two elastic regions are at least one groove or at least one incision in the pressure pad base body.

[0011] At least one groove is an elastic groove, which can advantageously achieve expansion and contraction in the elastic region of the pressure pad base body, especially achieve expansion and contraction between the first pressure pad base body region and the second pressure pad base body region.

[0012] The pair-arrangement of the elastic regions is conducive to achieving uniform expansion and contraction. Preferably, in the pair-arrangement, the first elastic region is located at an edge region of the pressure pad base body, and the second elastic region is located at the opposite edge region of the pressure pad base body. What is particularly advantageous about this pair-arrangement is that the pressure pad base body has an opening. For example, such an opening exists in a patellar pressure pad or an elbow pressure pad. Those skilled in the art are aware of such openings for accommodating the patella or the elbow, so that the pressure pad base body surrounds the patella or the elbow.

[0013] In a preferred embodiment, the pressure pad base body has an opening.

[0014] In a preferred embodiment, the pressure pad base body has at least two elastic regions, and these two elastic regions are separated by an opening in the pressure pad base body. Preferably, the two pair-arranged elastic regions are located on both sides of the opening, such as on the left and right sides or the upper and lower sides of the opening. Preferably, the diameter of the opening is at least 3 cm, that is, the opening can especially surround the patella, the elbow (i.e., the ulnar head) or the wrist (the ulnar head or the radial head of the wrist). Those skilled in the art are aware of the size and shape of such an opening. Such an opening usually surrounds a bone or cartilage prominence (protrusion) of the human body, and thus the size of the opening is determined thereby.

[0015] Preferably, the pressure pad (especially a patellar pressure pad, an elbow pressure pad or a wrist pressure pad) has exactly two elastic regions.

[0016] In a particularly preferred embodiment, at least one groove is located on the front side of the cushion base. In a particularly preferred embodiment, the cushion base has an outer side and an inner side facing the opening, wherein at least one groove starts from the outer side and does not reach the inner side or starts from the inner side and does not reach the outer side.

[0017] Preferably, the groove (i.e., the tensioning groove) is not a through-channel with openings on both sides, but a cut with only one-sided opening or no lateral opening.

[0018] Preferably, at least one groove (i.e., the tensioning groove) in the tensioning area has only one-sided opening or no lateral opening. Preferably, at least one groove (i.e., the tensioning groove) in the tensioning area has only one-sided opening.

[0019] Preferably, the tensioning area consists of at least one groove, such as one groove, two grooves, three grooves, four grooves, five grooves or more grooves.

[0020] Preferably, two paired tensioning areas have the same number of grooves and / or grooves with the same shape and size.

[0021] The number, width and depth of the groove (i.e., the tensioning groove) affect the tension.

[0022] Preferably, the width of the groove (i.e., the tensioning groove) is at least 0.1 mm. Preferably, the width of the groove (i.e., the tensioning groove) is at least 0.3 mm. Preferably, the width of the groove (i.e., the tensioning groove) is from 0.1 mm to 100 mm, especially from 0.3 mm to 50 mm. It has been proven that the above characteristics can be achieved particularly advantageously in this way. Preferably, the depth of the groove (i.e., the tensioning groove) is from 0.1 mm to 10 mm, especially from 0.5 mm to 3 mm. It has been proven that the above characteristics can be achieved particularly advantageously in this way.

[0023] According to a preferred improvement of the present invention, the groove (i.e., the tensioning groove) has a constant depth or at least two different depths in its longitudinal extension.

[0024] According to a preferred embodiment of the present invention, the depth of the groove (i.e., the tensioning groove) is at least 10% of the height of the base at the edge of the groove. The groove design can be similar to a "record groove", i.e., the width and depth of the groove are variable.

[0025] In a preferred embodiment, at least one raised portion is a convex pressing member. In a preferred embodiment, at least one convex pressing member is a convex point and / or a convex ridge. Those skilled in the art know the applicable raised portions. The cushion may also have a plurality of raised portions, especially different raised portions at different positions on the front side of the cushion.

[0026] The raised portion and the cushion base can be made of the same material or different materials. Preferably, the raised portion is made of a different material.

[0027] In a preferred embodiment, the hardness of the raised portion is higher than that of the pressing pad base.

[0028] In this variant, the mobility and massage function of the pressing pad can also be adjusted by material selection. Specifically, the base and / or the raised portion (especially the convex pressing member) are made of a viscoelastic material, allowing the pressing pad to undergo favorable deformation during application to achieve the desired massage effect. Specifically, the materials are selected to have different material stiffnesses or elasticities.

[0029] In this regard, according to a first preferred embodiment, the raised portion (especially the convex pressing member) is made of a material harder than the base material. In this way, the raised portion can transmit a higher point pressure to the area to be treated. However, this high-hardness structure reduces the mobility of the raised portion.

[0030] According to a second embodiment of the present invention, the raised portion (especially the convex pressing member) is made of a material softer than the base material, making it more elastic and less stiff compared to the base. In this way, the raised protrusion will increase mobility, especially possibly causing disordered movement of the multi-point protrusions of the convex pressing member.

[0031] In a preferred embodiment, the Shore hardness of the material of the raised portion (especially the convex pressing member) is at least 40 Shore 00, preferably at least 6 Shore A and at most 20 Shore A. In a preferred embodiment, the Shore hardness of the material of the raised portion (especially the convex pressing member) is at least 20 Shore A to at most 80 Shore A. In a preferred embodiment, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is at least 20 Shore A to at most 60 Shore A. In a preferred embodiment, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is at least 20 Shore A, more preferably at least 25 Shore A. In a preferred embodiment, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is at most 50 Shore A.

[0032] In a preferred embodiment, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is at most 49 Shore A, more preferably at most 45 Shore A. Preferably, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is at least 35 Shore A to at most 45 Shore A. Preferably, the Shore hardness of the material of the raised portion (especially at least one convex pressing member) is approximately 40 Shore A.

[0033] In a preferred embodiment, the Shore hardness of the cushion base material is at least 20 Shore 00 to at most 60 Shore 00, and / or the Shore hardness of the convex part (especially the convex pressing part) material is at least 40 Shore 00, preferably at least 6 Shore A to at most 20 Shore A.

[0034] Preferably, at least one convex part is spherical, pinecone-shaped, cylindrical, pyramidal, conical and / or mushroom-shaped. Depending on the use, different shapes can be adopted. If there are multiple convex parts, these convex parts can also adopt different shapes. According to the present invention, the convex parts and design of the cushion can ensure that the movable convex parts exert alternating pressure, such as the pressure exerted by a physiotherapist during massage, so as to maintain the pressure on sensitive nerves, lymphatic vessels and blood vessels for a long time. This is especially beneficial when the cushion is designed as a knee cushion, which will exert a corresponding massage effect on the meniscus base and Hoffa fat body.

[0035] Preferably, one or at least one of the multiple convex parts is perpendicular to the outer surface of the cushion base or inclined to the outer surface of the base in its longitudinal extension. The convex part being inclined relative to the outer surface means that a deformation direction is specified for the convex part during the treatment process. If the convex part is stressed in the reverse inclination direction, the convex part will exhibit extremely high rigidity and hardness; if it is stressed in the forward inclination direction, the convex part will rebound at a faster speed or with a smaller acting force. In this way, according to the application situation, the pressure distribution when the patient uses the cushion can be optimized and adjusted. If the convex part extends perpendicular to the outer surface of the base, the convex part can deform equally or deform with equal force in all directions transverse to its longitudinal extension.

[0036] In a preferred embodiment, especially when used as a patellar cushion, the cushion base has at least one wing part, preferably two wing parts, and the at least one wing part has at least one convex part, preferably convex points and / or convex ridges.

[0037] Preferably, the cushion is a knee cushion, an ankle cushion, a back cushion, an elbow cushion, an arm cushion or an abdominal cushion.

[0038] The cushion of the present invention is preferably used for a knee protection cushion, an elbow protection cushion or a wrist protection cushion. The cushion according to the present invention is preferably used for a knee protection cushion, that is, a patellar cushion.

[0039] In a preferred embodiment, the pressing pad base body has a cavity on the front side for at least one raised portion (in particular at least one convex pressing member), and the contour of the cavity at least substantially corresponds to the contour of at least one raised portion (preferably a convex pressing member), so that a groove is formed at least partially along the circumferential direction of the raised portion (preferably a convex pressing member) between the base body and the raised portion (preferably a convex pressing member). This groove is a spacing groove, rather than a tightness groove. The spacing groove is an additional groove of at least one tightness groove. The advantage is that through structurally easy-to-implement adjustments, the mobility of one or more raised portions can be enhanced, and at the same time, when using softer, harder, and / or smaller raised portions, the massage effect can be at least maintained or improved. The lateral distance between the base body and the convex pressing member is defined by this groove. This means that there is no direct lateral contact between the convex pressing member and in particular the raised portion arranged thereon and the base body. At least one convex pressing member is arranged in the base body in a floating manner. The technical effect is that when the pressing pad is in a stressed state during application, the supporting force of the base body on the pressing protrusion portion is weakened compared with the prior art, so that it is more likely to deform. In this way, a compact design of the height of the pressing pad (i.e., the dimension extending relative to the height of the pressing protrusion or the longitudinal extension dimension) can be achieved while maintaining the massage effect unchanged. Specifically, each pressing protrusion should be laterally flush with the base, that is, directly located at the outer edge of the base, and this outer edge defines the outer contour of the convex pressing member. In this regard, the groove directly cooperates with each convex pressing member, or can prevent each convex pressing member from being directly supported by the base body material laterally.

[0040] According to a preferred embodiment of the present invention, the groove extends along the entire circumference of the raised portion (in particular a convex pressing member). In this way, regardless of the design of the raised portion, it can be ensured that its mobility is achieved in the above-mentioned advantageous manner. By constructing a circumferential groove, the groove contour corresponds to the contour of the convex pressing member or the base, and this will also simplify the manufacture of the pressing pad.

[0041] Preferably, the width of the spacing groove (i.e., the distance from the base to the base body) is 0.3 mm. It has been proven that this can particularly advantageously achieve the above characteristics.

[0042] According to a preferred improvement of the present invention, the groove (i.e., the spacing groove) has a constant depth or at least two different depths in its longitudinal extension. The groove depth will change or affect the height range at which the base body and the convex pressing member are spaced from each other. As the groove depth decreases, the supporting effect of the base body on the base and each pressing protrusion is enhanced. As the groove depth increases, the influence and stiffness of the convex pressing member are correspondingly weakened. Observed along the circumferential direction of the base body, the target function of the convex pressing member can be set or adjusted through the groove width and the groove depth.

[0043] According to a preferred embodiment of the present invention, the depth of the groove (i.e., the spacing groove) is at least 10% of the height of the base body at the edge of the groove. The groove design can be similar to a "record groove", that is, the width and depth of the groove are variable.

[0044] According to a preferred embodiment of the present invention, the pressing member and the base body are made of the same material. Through such a spacer groove, the pressing protrusion obtains a favorable degree of mobility. Using the same material will reduce the manufacturing cost, but the preferred solution is that the base body and the base are integrally formed to form a one-piece main body, thereby ensuring a significant reduction in the overall manufacturing man-hours and costs of the pressure pad. By selecting an appropriate spacer groove width and / or spacer groove depth, the mobility of the pressing protrusion or the pressing member can be adjusted individually as needed.

[0045] The present invention also relates to an orthopedic aid including the pressure pad of the present invention, such as a bandage or an orthosis. In particular, the present invention relates to a bandage or an orthosis including the pressure pad of the present invention, such as a knee bandage or orthosis, an ankle bandage or orthosis, a back bandage or orthosis, an elbow bandage or orthosis, an arm bandage or orthosis, or an abdominal bandage or orthosis,

[0046] Preferably a knee bandage or orthosis, an elbow bandage or orthosis, or a wrist joint bandage or orthosis, more preferably a knee bandage or orthosis, and most preferably a knee bandage.

[0047] The orthosis or bandage of the present invention is characterized by the pressure pad of the present invention, thereby achieving the above advantages. Preferably, the orthosis is an elastic fabric orthosis or the bandage is an elastic fabric bandage, especially a knee orthosis or a knee bandage. Description of the Drawings

[0048] For more advantages, preferred features, and feature combinations, please refer to the above Summary of the Invention and the following Detailed Description. The present invention will be described in detail below with reference to the accompanying drawings. In the drawings:

[0049] Figure 1 A perspective top view of a favorable pressure pad is shown;

[0050] Figure 2 Shows Figure 1 A cross-sectional view of the tightening area of the pressure pad shown;

[0051] Figure 3 A cross-sectional view of a preferred embodiment of the pressure pad of the present invention is shown. Detailed Description

[0052] Figure 1Shows a favorable pressure pad 1 for an orthosis or bandage 2 (not shown in this figure). In the illustrated embodiment, the pressure pad is a patellar pressure pad. The pressure pad 1 has a pressure pad base body 3, which is substantially flat and made of an elastic material, in particular a viscoelastic material. The base body 3 has a three-dimensional outer contour, with its front side 4 serving as the treatment surface and the rear side 5 facing away from the front side 4. According to this embodiment, the outer contour of the base body 3 is characterized by a plurality of wings that project from the base ring, in particular radially outwards, and an oval opening is also formed in the base ring as an aperture 6. At the wings and the base ring, the pressure pad has a plurality of raised parts, namely convex pressing parts of different shapes, some of the convex pressing parts 7 being made of the same material as the base body, while some of the convex pressing parts 8a, 8b, 8c are made of a harder material.

[0053] According to the invention, the pressure pad has two pairwise arranged tensioning regions 9, 10, each formed by three grooves 11, 12, 13 and 14, 15, 16 cut into the base body 3, and these grooves serve as tensioning grooves. In this case, none of these tensioning grooves 11, 12, 13, 14, 15, 16 extend from the outer side 17 of the pressure pad base body 3 to the inner side 18 of the pressure pad base body (the inner side 18 faces the aperture 6). By the pairwise arranged tensioning regions 9, 10, the pressure pad base body 3 is divided into a first pressure pad base body region 19 and a second pressure pad base body region 20. In the case of a patellar pressure pad, the first pressure pad base body region 19 is located in the upper part and the second pressure pad base body region 20 is located in the lower part.

[0054] Due to the pairwise arranged tensioning regions 9, 10, when the knee is bent, the displacement amount between the upper first pressure pad base body region 19 and the lower second pressure pad base body region 20 is significantly greater than that of a conventional pressure pad without such tensioning regions. In terms of clock face positioning, the positions of the tensioning regions 9, 10 can be described as "2 o'clock and 10 o'clock directions". Of course, other positioning schemes may also be adopted, such as "3 o'clock and 9 o'clock directions" or "4 o'clock and 8 o'clock directions". But the basic feature is that all tensioning regions must be used in pairs to achieve the desired function.

[0055] Otherwise, such elasticity can only be achieved by reducing the hardness of the cushion substrate itself, but this will cause the patella positioning stability, the overall knee support, and the functions of the cushion such as the spacing maintenance of the elastic fabric covering the patella to no longer reach the required level. Ideally, the elastic regions (especially the elastic grooves) should be located on the left and right sides of the knee joint space. When the knee is flexed, the upper part 19 of the cushion must maintain its reference position relative to the upper end of the patella, so as to ensure that the convex parts (especially the convex pressing parts 8a) in the upper region of the cushion 1 remain in place. When using the cushion in the prior art, the convex point region above the oval of the cushion often displaces too much, so that the convex points on it "tilt", rather than applying massage pressure perpendicular to the body surface as expected. The vertical effect of such convex points is beneficial to achieving precise therapeutic massage stimulation of the main muscle group "vastus medialis". If the convex points in this region are tilted, the sensory-motor response of the muscle to the stimulation will not meet the requirements. According to the present invention, the paired elastic regions 9, 10 can advantageously stabilize the positioning of the two cushion substrate regions.

[0056] In the shown patellar cushion 1, a flank 21 with a convex pressing part 8a is added above the main muscle group "vastus medialis". When the muscle bears pressure, it produces a massage effect, releases contracture, and induces the sensory-motor response of the muscle.

[0057] According to the present invention, the elastic regions 9, 10 are combined with the convex pressing parts 8a for intermittent massage above the vastus medialis, and by relaxing the muscles that are painfully contracted in patients with osteoarthritis, especially by having a positive effect on the trigger points, the required analgesic effect is produced. This is equivalent to the analgesic effect that can be achieved by a physiotherapist's manual friction massage. Other analgesic advantages include reducing the tensile load of the patellar ligament, reducing the shear stress on the diseased patella, and reducing the risk of bandage slippage.

[0058] Those skilled in the art can understand that the significant advantages of combining the elastic regions 9, 10 with the convex pressing parts 8a can be extended to other cushions such as elbow cushions or wrist cushions.

[0059] In order to clearly show the elastic regions, Figure 2 A partial enlarged view of the cushion 1 is shown. The elastic region 10 is composed of three elastic grooves 14, 15, 16 opened on the front side 4 of the cushion substrate 3. None of these elastic grooves are through grooves, that is, they do not form a channel between the inner side 18 of the cushion substrate 3 facing the opening and the outer side 17 of the cushion substrate 3. Instead, the grooves 14, 16 only open to the outer side 17 of the cushion substrate 3, and the groove 15 only opens to the inner side 18 of the cushion substrate 3 facing the opening. The elastic region 10 divides the cushion substrate 3 into two cushion substrate regions 19, 20. Due to the paired arrangement of the elastic regions 10, 11, the convex pressing parts 8a in the upper first cushion substrate region 19 can maintain a more stable positioning during movement.

[0060] In order to clearly show the convex pressing parts with spacer grooves,Figure 3 shows Figure 1 a longitudinal cross-section of the shown pressure pad 1 in the region of the convex pressing member 8b (designated as 110 in this figure).

[0061] According to this embodiment, the depth of the cavity 108 is at least equal to the height of the base 111 used for the convex pressing member 110. The height of the pressing protrusion 114 is sufficient for it to protrude from the cavity beyond the base body 3 of the pressure pad 1. According to this embodiment, although the cavity 108 has a flat bottom surface, according to other embodiments (not shown in this figure), the bottom surface of the cavity can be non-planar. This can further affect the behavior of the pressing protrusion 114 during use. For example, the preferred bending direction can be specified.

[0062] The contour or inner contour of each cavity 108 at least substantially corresponds to the contour or outer contour of each convex pressing member 110 (especially each base 111). The contour of each cavity 108 is selected to at least partially retain a lateral distance x in the circumferential direction of each base 111. The lateral distance x forms a groove, i.e., an interval groove 120, between each convex pressing member 110 and the base body 3. The interval groove 120 at least partially extends along the circumference of each convex pressing member. The lateral distance x formed by the interval groove 120 is preferably from 0.1 mm to 3 mm, more preferably from 0.5 mm to 1.5 mm.

[0063] According to an advantageous embodiment, the interval groove 120 extends to cover the entire circumference of the convex pressing member 110. Preferably, the interval groove 120 has a constant depth t in its longitudinal extension.

[0064] Preferably, the depth t of the interval groove 120 is at least 10% of the height h of the base body 3 at the edge of the interval groove 120.

[0065] The interval groove 120 can ensure an advantageous influence on the elastic behavior and elastic direction of the pressing protrusion 114.

[0066] In this example, the pressing protrusion 114 is designed in the form of a convex point with a rounded end and is preferably made of a material harder than the base body 3. For a pressure pad where the pressing protrusion 114 is harder than the base body 3, the pressure pad 1 or the orthosis or bandage 2 having the pressure pad 1 can enhance the massage effect.

[0067] The depth t and width x of the interval groove 120 surrounding each pressing protrusion or base 111 determine the mobility of each relevant pressing protrusion 114. Since the material of the base body 3 adjacent to each pressing protrusion 114 is thinner or removed, each pressing protrusion 114 will deflect better due to the lateral distance x generated by the interval groove 120 and the freedom of movement will be increased in the extended edge region. Whether each pressing protrusion 114 is completely sunk into the cavity 108 (e.g., flush with the outer surface 119 of the base body 3) or each pressing protrusion 114 protrudes beyond the outer surface 119 (as shown in this embodiment), the above technical effects are not affected.

[0068] The spacer groove 120 helps to make the overall size of the press protrusion 110 smaller than the flush placement situation without a groove on the flat placement surface. The press protrusion 110 is placed in the area of the spacer groove 120 in a floating manner.

[0069] For some applications, it may be advantageous that the press bumps or press protrusions 110 do not protrude or only slightly protrude from the base body 3, but their respective positions (especially the positions relative to their press bumps 114) can move freely. According to another embodiment, the ends of the press bumps 114 are particularly flush with the outer surface 119, as Figure 3 shown by the dashed line in
