Description

Technical Field

[0001] This invention relates to pressure pads, particularly pressure pads for orthopedic assistive devices, which include at least one protruding element. The invention also relates to the use of the pressure pads of the invention in orthopedic or motor assistive devices (especially orthoses or bandages), and orthopedic or motor assistive devices (especially orthoses or bandages) having the pressure pads of the invention. Background Technology

[0002] Currently known pressure pads have various implementation schemes and are suitable for a variety of preventive and therapeutic applications. Various pressure pads can be found in patent documents such as DE 27 22 563 C2, EP 0 598 291 A1, and EP 0 600 218 A2.

[0003] Pressure pads made of two materials or components can also be found in patent document DE 297 01 001 U1. Patent document EP0 496 071 A1 describes a pressure pad made of a soft material, in which at least one friction core made of a hard or incompressible material is arranged. This friction core is intended for frictional massage, that is, dynamic friction is generated by the movement of the friction core relative to the soft tissue of the pressure pad wearer, thereby massaging pain points.

[0004] Patent document DE 10 2019 212 740 B3 describes a pressure pad that protrudes towards the wearer.

[0005] Existing pressure pads can apply pressure to a large area of ​​the attached tissue, or disperse and / or shield the pressure on that area, but such pressure pads cannot or can only barely apply specific pressure, such as applying stronger or weaker pressure to specific points.

[0006] When using existing pressure pad technology, pressure can be applied vertically to the skin. This makes it impossible to achieve lateral pressure, especially to cause the pressure element to move, thus failing to produce a massage effect beyond simple pressure.

[0007] Furthermore, the pressure applied by pressure bodies in existing technologies is often insufficient. Summary of the Invention

[0008] In view of the above, the technical problem to be solved by the present invention is to provide an improved pressure pad, especially a pressure pad that can apply pressure at specific precise points in addition to applying planar pressure. Specifically, the technical problem to be solved by the present invention is to provide a pressure pad that can improve the massage effect, especially by improving the massage effect through the movement of the pressure body. Specifically, the technical problem to be solved by the present invention is to provide a pressure pad that can apply relatively strong pressure, especially in conjunction with the massage effect.

[0009] The technical problem faced by the present invention is solved by proposing the pressure pad described in claim 1.

[0010] To solve the above-mentioned technical problems, the present invention provides a pressure pad for orthopedic or sports assistive devices, comprising a pressure pad base component made of a first material, wherein the pressure pad base component has an active surface and a pressure-bearing surface, wherein the pressure pad base component is provided with at least one protrusion, wherein the protrusion has at least one protrusion area protruding from the active surface of the pressure pad base component, characterized in that the protrusion has a pressure-bearing area protruding from the pressure-bearing surface of the pressure pad base component.

[0011] In this invention, the protruding part not only protrudes from the functional surface of the pressure pad base like a conventional pressure pad, but also additionally protrudes from the bearing surface. In cross-section, the pressure pad is divided into three layers: the middle layer is the pressure pad base layer, in which the pressure pad base is located; the functional layer, from the pressure pad base layer towards the wearer, in which the protruding part's protruding area is located; and the bearing layer, from the pressure pad base layer towards another direction, especially towards the pressure pad support portion (preferably where a pressure pad support portion exists), in which the pressure-bearing area of ​​the protruding part is located. The pressure pad base layer, located between the functional layer and the bearing layer, can be considered as the "thickness" of the pressure pad base.

[0012] This allows for advantageous control of at least one raised element on a second layer (i.e., the pressure-bearing layer) facing away from the user's body via a pressure-bearing area. This "outward" control enhances the pressure applied by the raised element. The raised element is controlled by external pressure, such as pressure from the padding support (e.g., knitted fabric or bandage base), acting on the pressure-bearing area of ​​the raised element on the pressure-bearing layer, thus generating different massage movements as the user moves, through the raised areas on the surface facing the body (i.e., the action layer). When the raised element is controlled via the pressure-bearing area, its basic movement is tilting, especially outward (i.e., away from the common center point). This tilting movement is advantageously generated during bandaging and movement. However, when a reverse force is applied, the raised element also tilts inward, i.e., towards its common imaginary center.

[0013] To achieve the function according to the invention, it is not necessary for the pressure pad support to generate counter-pressure. Such counter-pressure could also be generated by the chair back, the resting hand, etc., without the pressure pad support covering the relevant area of ​​the pressure pad. According to the invention, even if the pressure pad is applied directly to a body part (e.g., by adhesive), the raised point elasticity technology achieved through the pressure-bearing area can function as long as additional force can be applied to the pressure-bearing layer. Therefore, while the pressure pad support is advantageous, it is only an option, not a necessity.

[0014] By applying pressure to both sides of the pad in combination, it is possible to generate complex movement patterns of the raised elements in a favorable manner, which vary with each movement of the patient.

[0015] In a favorable manner, the lateral movement of these protruding parts will also exhibit a certain degree of chaos depending on the direction of the applied force vector, which will enhance the massage effect.

[0016] Compared to existing protrusions, the raised dots according to the present invention possess significantly higher degrees of freedom and mobility, thus exhibiting particular chaos. The advantage of this effect is that the mechanoreceptors located beneath the skin do not easily adapt to the constantly changing elastic movements of the raised dots, thereby prolonging the massage effect. Hand massage involves "chaotic" massage, meaning that each massage therapist's technique is not exactly the same as the last. Therefore, the massage effect produced by the pressure pad of this invention is more like a manual massage than that produced by conventional pressure pads. The raised points, combined with the pressure-bearing parts, can achieve movable protrusions in an advantageous manner, thereby realizing the principle of intermittent massage. While immovable protrusions on the pressure pad only generate pressure acting on skin receptors, which adapt to this pressure and cease to emit effective signals in a relatively short time, the movable raised points according to the invention can generate alternating pressure, just like the pressure applied by a massage therapist during a massage, thus ensuring continuous pressure on lymphatic vessels and blood vessels. This is particularly advantageous because, for example, in knee pressure pads, it applies a corresponding massage effect to the base of the meniscus and the Hofmeister pad. In an advantageous manner, the raised points can move chaotically in different directions according to the applied force vector.

[0017] Within the scope of this invention, "pressure pad" particularly refers to a pressure mat, the shape of which is formed, in particular, by a pressure pad base element. The pressure pad base element can take any suitable shape. Conventional pressure pads typically use a flat base surface as the pressure pad base element. In this case, protrusions (especially raised points) can protrude from such a base surface. The pressure pad of the present invention particularly has a first base surface or basic surface facing the user when the pressure pad is used, i.e., the working surface. Preferably, the pressure pad is substantially sheet-like in design. Such a pressure pad also has a second base surface or basic surface facing away from the user when the pressure pad is used, i.e., the bearing surface.

[0018] Those skilled in the art will recognize the typical uses of pressure pads. Pressure pads (including the pressure pad of the present invention) are particularly suitable for applying pressure to certain body parts, such as the back or knee areas. The pressure pad is positioned and pressed onto the corresponding body part via other devices, especially motion aids, bandages, or orthotics.

[0019] Preferably, the pressure pad base component is plate-shaped, i.e., a plate. The plate can be planar, curved, or arched. The plate can have one or more openings.

[0020] The protrusion area and the bearing area can be positioned side by side or vertically arranged on the protrusion component. For example, the protrusion area and the bearing area can be two different entities protruding in different directions, or they can be formed by a single entity where both the self-acting surface and the bearing surface protrude.

[0021] In a preferred embodiment, the protrusion has a bridging element and is fastened to the pressure pad substrate via the bridging element. The bridging element may be located between the pressure-bearing area and the pressure pad substrate, or the pressure-bearing area itself may form the bridging element.

[0022] The advantage of this bridging part is that it can achieve a clear and controllable rebound motion, rather than the possible bouncing in all directions like "floating rebound".

[0023] In a preferred embodiment, at least one protrusion is movable.

[0024] Preferably, the protrusion is a pressure enhancer. The pressure enhancer is used to apply point pressure, which is stronger than the surface pressure applied by the pad base.

[0025] In one preferred embodiment, the pressure pad has at least two protrusions. In another preferred embodiment, the pressure pad has at least two to at most twenty protrusions. In yet another preferred embodiment, the pressure pad has several protrusions.

[0026] The pressure pad base can be positioned with several protrusions so that when the pressure pad is used, these protrusions can apply precise point pressure to specific points (such as trigger points, acupoints, or infrapatellar fat pads).

[0027] In addition to at least one protrusion, the pad may also have additional friction elements or other pad pressure elements, such as pressure elements made of the pad base material.

[0028] In one preferred embodiment, the pressure pad base and at least one bump are integrally formed and / or made of the same material. In another preferred embodiment, the pressure pad base and at least one bump are integrally formed. In yet another preferred embodiment, the pressure pad base and at least one bump are made of the same material.

[0029] In one preferred embodiment, the pressure pad base has at least one orifice, wherein at least one protrusion is positioned in the orifice.

[0030] According to the present invention, the protrusion has a pressure-bearing area and a protrusion area. Here, the protrusion is preferably connected to the pressure pad base member via or with the pressure-bearing area. The pressure-bearing area is preferably located between the end of the protrusion forming the protrusion area and the end of the protrusion connected to the pressure pad base member, or the pressure-bearing area is formed at the end of the protrusion connected to the pressure pad base member.

[0031] In an alternative embodiment, particularly in the case of multiple interconnected protrusions, the protrusion area can be connected to the pressure pad base, i.e., the protrusion area is located between the pressure pad base and the pressure-bearing area. Preferably, in such an embodiment with multiple protrusions, the pressure-bearing areas of these protrusions are interconnected.

[0032] In one preferred embodiment, the pressure-bearing area of ​​at least one protrusion has a pressure-bearing surface and / or is located within the intermediate longitudinal region of at least one protrusion and / or at the bridging member of at least one protrusion. In another preferred embodiment, the pressure-bearing area of ​​at least one protrusion has a pressure-bearing surface. In another preferred embodiment, the pressure-bearing area of ​​at least one protrusion is located within the intermediate longitudinal region of at least one protrusion. In another preferred embodiment, the pressure-bearing area of ​​at least one protrusion is located at the bridging member of at least one protrusion.

[0033] The bearing surface of the pressure zone can be designed in various shapes, such as anvil, wing, or disc. Different geometries can be adopted to better withstand pressure on the bearing surface. Depending on the geometry of the bearing surface, larger or smaller forces can be fed back to the action plane in a favorable manner. The larger the bearing surface of the pressure zone, the greater the force input to the action plane, and therefore the more rigid its effect.

[0034] Multiple pressure-resistant surfaces can also be set in the pressure-bearing area, such as two mirror-symmetrical pressure-resistant surfaces.

[0035] In a preferred embodiment, the pressure-bearing area of ​​at least one protrusion member has an airfoil or disc-shaped structure.

[0036] In the unpressurized state, the self-pressing pad base (i.e., the pad base layer) of the bump area preferably protrudes at an angle of approximately 90°, especially at a 90° angle toward the user. However, the bump area may also protrude toward the user at different angles from the self-pressing pad base (i.e., the pad base layer) in the unpressurized state.

[0037] To improve the flexibility of at least one convex part, the convex part may include a thinned portion or a thickened portion, for example, between the convex area, the pressure bearing area, between the convex area and the pressure bearing area, or between the pressure bearing area and the end of the convex part connected to the pressure pad base. Hinge membranes, wedges, etc. may also be used.

[0038] The pressure pad has at least one protrusion, preferably two, three, four, five, ten or more protrusions. Two or more (e.g., three) protrusions can be interconnected, especially via bridging portions. Preferably, two, three or more protrusions are interconnected via their pressure-bearing areas.

[0039] Preferably, multiple (especially two or three) bump areas can be interconnected via their pressure-bearing areas (i.e., on the pressure-bearing surface), especially via bridging portions. This allows multiple consecutive bump elements to form "bump nests" of 2, 3, 4, or other sizes.

[0040] In addition to simple protrusions, any number of protrusions, such as two to ten, especially two to five, or even three or four, protrusions can be connected on the pressure-bearing surface, particularly via bridging. When pressure is applied directly to the pressure-bearing surface of such a protrusion nest in a centered manner, these multiple protrusions will deflect outwards. If pressure is applied offset instead of in a centered manner, the protrusions will spring back in different directions on the side facing the body.

[0041] The pad can also have some independent bumps and some interconnected bumps.

[0042] In one preferred embodiment, the pressure pad base and at least one protrusion are integrally formed, especially from the same material.

[0043] In one preferred embodiment, the pressure pad base is at least partially embedded in the sleeve. In another preferred embodiment, the pressure pad base is completely embedded in the sleeve.

[0044] Therefore, the shape of the sleeve can determine the shape of the pressure pad.

[0045] Preferably, the pressure pad base is completely enclosed by the sleeve, for example, covered inside the sleeve.

[0046] By preferably completely encasing at least one pressure pad base element in a covering material, especially a soft covering material such as silicone, not only can the advantages of the above-mentioned application technology be achieved, but it is also beneficial to simplify the manufacturing of the pressure pad of the present invention, because even if there is a pressure-bearing area with protrusions, the second base surface (i.e. the pressure-bearing surface) of the pressure pad base element facing away from the user can be easily made into a flat surface.

[0047] Those skilled in the art will know the materials suitable for the sheath, especially for conventional one-piece flexible pads.

[0048] Preferably, the sheath contains a viscoelastic material in at least one region of the protrusion. Preferably, the sheath is viscoelastic in at least a portion of the region. Preferably, the sheath is viscoelastic. Preferably, the sheath is made of a viscoelastic material.

[0049] Preferably, the sheath is made of plastic, silicone, or rubber. The material can also be a thermoplastic elastomer, such as polyurethane.

[0050] Preferably, the material of the cover is flexible and / or stretchable so that the cover can adapt to the user's body shape when the pad is worn.

[0051] Preferably, the sheath material does not contain textile materials. However, in an alternative embodiment, the sheath may also be additionally covered or otherwise coated with a textile sheath.

[0052] Of course, the sheath material can also be made of a mixture of multiple materials, especially a mixture of at least two of the above-mentioned materials.

Detailed Implementation

[0097] Figure 1 A schematic cross-sectional view of the cushion base 10 and its protrusion 20 is shown. The cushion base 10 extends in a sheet shape and is located in the middle layer, namely the cushion base layer A, in the abstract structure of a three-layer cushion. The protrusion 20 is connected to the cushion base 10 via a pressure-bearing area 21. The pressure-bearing area 21 is located below the cushion base layer A, i.e., in the pressure-bearing layer B. The pressure-bearing area 21 is connected to the protrusion area 22, at which the protrusion 20 terminates. The protrusion area 22 is located above the cushion base layer A, i.e., in the functional layer C. The middle layer is the cushion base layer A, the functional layer C is the direction from the cushion base layer A toward the cushion wearer, and the pressure-bearing layer B is the direction from the cushion base layer A toward another direction, especially the direction of the cushion support portion (preferably where the cushion support portion exists). The cushion base layer A is located between the functional layer C and the pressure-bearing layer B and can be considered as the "thickness" of the cushion base 10.

[0098] The pressure-bearing area 21 of the protrusion 20 has two mirror-symmetrical wing-shaped pressure-bearing surfaces 23, which can increase the pressure-bearing capacity.

[0099] Figure 2 The back pressure pad 200 of the present invention is shown. Figure 2 A shows the functional surface 201 of the pressure pad base 10 facing the wearer. Figure 2 B shows the pressure-bearing surface 202 of the back padding base 10 facing away from the wearer and towards the (optionally present) pressure-bearing portion. The back padding has a sheet-like pressure-bearing base 10 and a plurality of protrusions 20, 30 distributed on the pressure-bearing base 10. Ten protrusions are individual protrusions 20, and the other 18 protrusions form three interconnected protrusions 30. From Figure 4 The exact structure of the convex parts 20 and 30 can be seen.

[0100] The common feature of all the protrusions 20 and 30 is that the working surface 201 of the self-pressure pad base 10 in the protrusion areas 22 and 32 protrudes, and the bearing surface 202 of the self-pressure pad base 10 in the bearing areas 21 and 31 protrudes.

[0101] Figure 3 It shows Figure 2 The following are two other perspectives of the back pressure pad of the present invention. Figure 3A shows an oblique view of the working surface 201 of the pressure pad base 10 facing the wearer. Figure 3 Figure B shows a side view. As shown in the figure, the protrusions 20 and 30 protrude from the working surface 201 of the pressure pad base 10 with their protrusion areas 22 and 32, and from the bearing surface 202 of the pressure pad base 10 with their bearing areas 21 and 31.

[0102] Figure 4 It shows Figure 2 and Figure 3 Two transverse sectional views of the pressure pad basic component 10 shown.

[0103] Figure 4 A shows a separate protrusion 20. The protrusion 20 is connected to the pressure pad base 10 via a pressure-bearing region 21. The pressure-bearing region 21 is located below the pressure-bearing surface 202. The pressure-bearing region 21 is in contact with a protrusion region 22, at which the protrusion 20 terminates. The protrusion region 22 is located above the working surface 201. The pressure-bearing region 21 of the protrusion 20 has two mirror-symmetrical wing-shaped pressure surfaces 23, which increase the pressure resistance.

[0104] Figure 4 B illustrates three combined and interconnected bump members 30. Each bump member 30 is connected to the pressure pad base member 10 via its respective bump area 32. The bump area 32 is located above the working surface 201. The bump area 32 is in contact with the pressure bearing area 31. The pressure bearing area 31 is located below the pressure bearing surface 202. The three bump members 30 are interconnected with their respective pressure bearing areas 31, thus forming a "bump nest".

[0105] Figure 5 The present invention illustrates a knee pad 300. The knee pad 300 includes: a pad base 10 having six protrusions 30 forming two triplets and two additional optional pressure members 40; a soft cover 50 of a typical knee pad shape, which covers the pad base 10; and additional optional pressure members 60, which are also covered within the cover. Figure 5 A shows a top view of the pressure pad 300 and the pressure pad base 10 facing away from the body, i.e., the pressure-bearing surface 202. Figure 5 B shows a top view of the pressure pad 300 and the pressure pad base component 10 facing the body, i.e., the working surface 201. From Figure 6 The exact structure of the pressure pad base 10 and the protrusion 30 can be seen.

[0106] Figure 6 It shows Figure 5 The knee pad shown is the basic component 10. Figure 6 A shows a top view of the pressure pad base 10 facing away from the body, i.e., the pressure-bearing surface 202. Figure 6B shows a top view of the pressure pad base 10 facing the body, i.e., the working surface 201. The pressure pad base 10 has six protrusions 30 forming two groups of three, and two additional optional pressure members 40. Each group of three individual protrusions 30 is connected to the pressure pad base 10 via their respective protrusion areas 32. The protrusion areas 32 are located above the working surface 201. The protrusion areas 32 are in contact with the pressure-bearing areas 31. The pressure-bearing areas 31 are located below the pressure-bearing surface 202. The three protrusions 30 are interconnected with their respective pressure-bearing areas 31, thus forming a "protrusion nest".

[0107] Figure 7 Three different embodiments of the pressure pad base 10 and its protrusion 20 are schematically illustrated. In all three embodiments A, B, and C, the planar pressure pad base 10 has an orifice 11 through which the protrusion 20 passes, such that the pressure-bearing area 21 and the protrusion area 22 protrude in opposite directions from two surfaces of the pressure pad base 10. In all three embodiments, the protrusion 20 is connected to the pressure pad base 10 via a bridging member 24.

[0108] The differences between these three implementation schemes A, B, and C lie in the shape and positioning of the pressure-bearing area 21, the protrusion area 22, and the bridging component 24: In implementation scheme A, the protrusion area 22 is in the shape of a pin and is located directly above the pressure-bearing area 21.

[0109] In implementation scheme B, the protrusion area 22 is arrow-shaped. Here, the pressure-bearing area 21 can be regarded as a segment of the bridging component 24.

[0110] In implementation scheme C, the protrusion area 22 is pin-shaped and located at the outer end of the bridging member 24. The pressure-bearing area 21 is located in the middle region of the bridging member 24.

[0111] In implementation schemes A and C, the pressure-bearing area 21 of the protrusion 20 has two mirror-symmetrical wing-shaped pressure-bearing surfaces 23, which can increase the pressure-bearing capacity.

[0112] Figure 8The illustration schematically depicts an embodiment of a pressure pad 400 in which the protrusion 20 and the pressure pad base 10 are not fixedly connected. Here, the protrusion 20 and the pressure pad base 10 are encapsulated within a soft sheath 50. The planar pressure pad base 10 has an opening 11 through which the protrusion 20 passes, causing the pressure-bearing area 21 and the protrusion area 22 to protrude in opposite directions from two surfaces of the pressure pad base 10. The protrusion 20 is not fixedly connected to the pressure pad base 10 via a bridging portion or other means; instead, both are positioned by the material of the sheath 50. In this case, the floating protrusion 20 also enhances the functional effect on the working surface due to the counter-pressure. In this example, the pressure area 21 is subjected to a counter-pressure due to the pressure support portion 500 (e.g., knitted or woven fabric). This is because when the pressure support portion 500 is tensioned, it presses against the pressure area 21, which in turn transmits the pressure through the orifice 11 to the protrusion area 22 that is against the wearer's body.
