Description

TECHNICAL FIELD

[0001] The present invention relates to pressure pads, in particular for orthopedic aids, comprising at least two protruding elements and at least one pressure element. The present invention also relates to the use of the pressure pad according to the invention for an orthopedic aid or a movement aid, in particular an orthosis or a bandage, and to an orthopedic aid or a movement aid, in particular an orthosis or a bandage, having a pressure pad according to the invention. BACKGROUND

[0002] Pressure pads are known in various embodiments and are used for various prophylactic and therapeutic purposes. Various different pressure pads are known, for example from patent documents DE 27 22 563 C2, EP 0 598 291 Al and EP 0 600 218 A2.

[0003] Pressure pads made of two materials or components are also known from patent document DE 297 01 001 Ul. Patent document EP 0 496 071 Al 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. The friction core is intended for friction massage, i.e. dynamic friction is generated by the movement of the friction core relative to the soft tissue of the wearer of the pressure pad, whereby the painful points are massaged.

[0004] Patent document DE 10 2019 212 740 B3 describes a protuberance protruding from the pressure pad in the direction of the wearer, wherein at least two viscoelastic active columnar protuberances are connected to one another.

[0005] The prior art pressure pads can exert pressure over a large area of the attached tissue or distribute and / or shield the pressure exerted on this area, but it is not possible or only possible with difficulty to exert a specific pressure, for example a stronger or weaker pressure on a specific point, with such pressure pads.

[0006] With the prior art pressure pads, it is also possible to exert pressure vertically onto the skin. It is not possible to achieve lateral pressure, in particular to cause the pressure elements to move, and thus to generate a massage effect beyond pure pressure.

[0007] Furthermore, the pressure exerted by the pressure bodies of the prior art is often insufficient in strength. SUMMARY

[0008] The technical problem to be solved by the present application is to provide an improved pressure pad, in particular a pressure pad which is capable of exerting a defined point pressure in addition to a planar pressure. In particular, the technical problem to be solved by the present application is to provide a pressure pad which is capable of improving the massage effect, in particular by different movements of the pressure body. In particular, the technical problem to be solved by the present application is to provide a pressure pad which, when a varying pressure is exerted on the pressure pad basic element, allows the convex protuberances to be tilted in a defined manner, thereby achieving the primarily desired massage direction. At present, the prior art does not provide a sufficient solution to the problem that the convex protuberances on the pressure pad are capable of performing a repetitive movement in a defined direction like the fingers of a masseur / physiotherapist in a hand massage.

[0009] The technical problem to be solved by the present application is solved by the pressure pad according to claim 1.

[0010] In order to solve the above-mentioned technical problem, the present application provides a pressure pad for an orthopedic or sports aid, comprising a pressure pad basic element made of a first material, wherein the pressure pad basic element has an action surface and a pressure receiving surface, wherein the pressure pad basic element is provided with at least one convex element, wherein the convex element has at least two convex regions which protrude from the action surface of the pressure pad basic element, wherein the convex element has at least one pressure receiving region which protrudes from the pressure receiving surface of the pressure pad basic element, wherein the at least one pressure receiving region is connected to the at least two convex regions.

[0011] In the present application, the convex element protrudes not only from the action surface of the pressure pad basic element, as is the case with conventional pressure pads, but also additionally from the pressure receiving surface. Viewed in cross section, the pressure pad is divided into three levels: a pressure pad basic level in which the pressure pad basic element is located, an action level which faces in the direction of the pressure pad wearer from the pressure pad basic level, in which the convex regions of the convex element are located, and a pressure receiving level which faces in the other direction, in particular in the direction of the pressure pad carrier, from the pressure pad basic level, in which the pressure receiving regions of the convex element are located. The pressure pad basic level is located between the action level and the pressure receiving level and can be regarded as the "thickness" of the pressure pad basic body.

[0012] In this way, the at least one convex element can be actuated by means of the pressure receiving regions on the second level, i.e. the pressure receiving level, which faces away from the user's body, in an advantageous manner. This "external" actuation can enhance the pressure exerted by the convex element in an advantageous manner. By means of pressure from the outside, for example from the pressure pad carrier, for example a knitted fabric or a bandage base, the pressure receiving regions of the convex element are acted upon in the pressure receiving level, thereby actuating the convex element, and different massage movements are produced by the convex regions on the action surface, i.e. the action level, which faces the body, when the user is active.

[0013] If the plurality of convex point regions on the pressure layer are connected to one another, these convex point regions advantageously perform an expansion movement when force is applied from the pressure layer. If, on the other hand, a counterforce is applied from the action surface to the pressure surface, the convex point regions perform a grasping movement, i.e. in fact converge towards the imaginary common centre. This enables different massage effects. The provision of the convex points without a pressure element on the struts as described in DE 10 2019 212 740 B3 cannot reproduce the effects described above.

[0014] In order to achieve the functions according to the application, it is not necessary for a counterpressure to be generated by the pressure pad carrier. This counterpressure can also be generated by the backrest, the palms of the hands placed thereon, etc., without the pressure pad carrier having to cover the relevant region of the pressure pad. According to the application, the convex point spring technology achieved by the pressure regions can be used even if the pressure pad is applied directly to the body part, for example by adhesive, provided that additional force can be applied on the pressure layer. By means of this, the pressure pad carrier is advantageous, but is only an optional item, not a mandatory item.

[0015] By means of the combination of the pressure applied on both sides of the pressure pad, it is possible to produce complex convex element movement patterns in an advantageous manner, which are different for each movement of the patient.

[0016] In an advantageous manner, this lateral movement of the convex elements also exhibits a certain chaotic nature depending on the direction of the force vector.

[0017] Compared to the protuberances in the prior art, the convex elements connected via the pressure pad base element according to the application, i.e. the particularly preferred convex elements, spring more powerfully and more controlled than without guided movement. The targeted controlled tilting or springing movement is never exactly the same as the subsequent movement, since the pressure or tension applied to the pressure region always produces a slightly different movement pattern. The advantage of this effect is that the mechanoreceptors located under the skin do not easily adapt to the constantly changing springing movement of the convex elements, so that the massage effect is prolonged, which can also be called targeted chaotic movement, and the undesired movement of the convex elements is significantly reduced.

[0018] The hand massage therapy involves a "chaotic" massage, i.e. each massage movement of the masseur is not 100% identical to the other, so that the massage effect of the pressure mat according to the invention is more similar to a hand massage than the massage effect of a conventional pressure mat. The combination of the protrusion and the pressure- receiving area enables an active protuberance to be achieved in a favorable manner, so that the principle of intermittent massage is implemented. While the immovable protuberances on a pressure mat only produce a pressure effect on the skin receptors, which the skin receptors then adapt to within a relatively short time and no longer signal effectively, the active protrusion according to the invention produces an alternating pressure, as is applied by a masseur during a massage, so that the pressure effect on the lymph vessels and blood vessels is sustained. This advantage is particularly advantageous, for example, in a knee pressure mat, in which the corresponding massage effect is exerted on the meniscus base and Hoffa fat pad. In a favorable manner, the protrusion is moved in a targeted chaotic manner in different directions depending on the force vector.

[0019] Within the scope of the present invention, a "pressure mat" is in particular a pressure pad, the shape of which is in particular formed by a pressure mat base.

[0020] The pressure mat base can take any suitable shape. Conventional pressure mats usually have a flat base surface as a pressure mat base. In this case, the protrusions, in particular the protrusions, can protrude from such a base. The pressure mat according to the invention in particular has a first base surface or base surface, which faces the user when the pressure mat is used, i.e. an active surface. Preferably, the pressure mat is designed essentially in the form of a sheet. Such a pressure mat also has a second base surface or base surface, which faces away from the user when the pressure mat is used, i.e. a pressure-receiving surface.

[0021] Typical uses of pressure mats are known to the person skilled in the art. Pressure mats, including the pressure mat according to the invention, are in particular suitable for exerting pressure on certain body parts and for partially implementing a massage effect, for example in the area of the back or the knee. The pressure mat is positioned and pressed onto the respective body part via other devices, in particular sports aids, bandages or orthoses.

[0022] Preferably, the pressure mat base is in the form of a plate, i.e. a plate element. The plate element can be planar, curved or arched. The plate element can have one or more cutouts.

[0023] The protrusion area and the pressure-receiving area can be located on the protrusion element next to each other or one above the other. For example, the protrusion area and the pressure-receiving area can be two different entities that protrude in different directions or can be formed by a single entity that protrudes from both the active surface and the abutment surface.

[0024] In a preferred embodiment, the protrusion element has an abutment element. The abutment element can be located between the pressure-receiving area and the pressure mat base, or the pressure-receiving area itself forms the abutment element.

[0025] Preferably, at least one pressure-receiving area is an abutment element.

[0026] The bridge member advantageously contributes to a well-controlled internal spring movement (which can be enhanced by the optional protrusion) that will cause a lateral relative movement to a pin, for example on the optional protrusion, without causing a freely omnidirectional "floating springing".

[0027] In a preferred embodiment, the at least two protrusion areas are active.

[0028] Preferably, the protrusion areas are pressure enhancement members. Pressure enhancement members are used to exert point pressure, which is stronger than the surface pressure exerted by the pressure pad base member.

[0029] Preferably, the at least two protrusion areas are columnar protrusions, as known to the skilled person.

[0030] In a preferred embodiment, the pressure pad has at least two protrusion members. In a preferred embodiment, the pressure pad has at least two to at most twenty protrusion members. In a preferred embodiment, the pressure pad has a number of protrusion members.

[0031] A number of protrusion members can be positioned on the pressure pad base member of the pressure pad, so that when the pressure pad is used, these protrusion members can exert precise point pressure on specific points, for example trigger points, acupoints, muscles, tendons, muscle or tendon attachment points or infrapatellar fat pads.

[0032] In addition to the at least one protrusion member, the pressure pad can have additional friction members or other pressure pad pressure members, for example pressure members made of the pressure pad base member material.

[0033] In a preferred embodiment, the at least one protrusion member consists of a softer material than the pressure pad base member. In a preferred embodiment, the at least one protrusion member is made of a softer material than the pressure pad base member.

In an embodiment, the pressure pad base member and the at least one protrusion member are integrally formed. In an embodiment, the pressure pad base member and the at least one protrusion member are made of the same material.

[0035] In a preferred embodiment, the pressure pad base member has at least one aperture, wherein the at least one protrusion member is positioned in the aperture.

[0036] In a preferred embodiment, the protrusion areas can be connected to the pressure pad base member, i.e. the protrusion areas are positioned between the pressure pad base member and the pressure receiving areas. In this embodiment, the plurality of protrusion members are preferably connected to each other via one or more pressure receiving areas.

[0037] In a preferred embodiment, the at least two protrusion areas are positioned at the edge of the aperture and the pressure receiving areas are positioned in the aperture.

[0038] In a preferred embodiment, three, four or five nub regions are located at the edge of the orifice and the pressure region is located in the orifice.

[0039] The effect of the nub member in combination with the pressure member can be advantageously enhanced by further increasing the fit of the nub member at the orifice or orifice edge, for example by providing a protrusion or flange at the orifice or orifice edge for the nub member to sit on, which can extend the travel of its retraction or expansion and thus intensify the massage effect.

[0040] In a preferred embodiment, the nub member has a protrusion, in particular at the orifice edge. In a preferred embodiment, at least two nub regions are located on the protrusion.

[0041] Preferably, the at least one nub member has two, three, four, five, six, seven, eight, nine, ten or eleven nub regions.

[0042] Preferably, the at least one nub member has two, three or four nub regions.

[0043] Preferably, the at least one nub member has at least three nub regions.

[0044] Preferably, the at least one nub member has three, four or five nub regions.

[0045] Preferably, the at least one nub member has three or four nub regions. Preferably, the at least one nub member has three nub regions. Preferably, the at least one nub member has four nub regions.

[0046] In the unpressurized state, the nub regions preferably protrude at an angle of about 90° from the pressure pad base (i.e. the pressure pad base level), in particular 90° towards the user direction. However, the nub regions can also protrude at a different angle from the pressure pad base (i.e. the pressure pad base level) towards the user direction in the unpressurized state.

[0047] In order to increase the flexibility of the at least one nub member, the nub member can comprise thinning or thickening, for example between the nub regions, the pressure region, the nub regions and the pressure region or the nub member end where the pressure pad base is connected, or a hinge film, wedge, etc. can be used.

[0048] The pressure pad has at least one nub member, preferably two, three, four, five, ten or more nub members.

[0049] In particular, the plurality, in particular two, three, four or five nub regions are connected to each other via the pressure region (i.e. on the pressure level), in particular via a bridge. In this way, a "nub nest" of 2, 3, 4 or other sizes can be formed from the plurality of contiguous nub regions.

[0050] In a preferred embodiment, the pressure pad base element is at least partially embedded in the cover. In a preferred embodiment, the pressure pad base element is completely embedded in the cover.

[0051] By this, the shape of the cover can determine the shape of the pressure pad.

[0052] Preferably, the pressure pad base element is completely wrapped by the cover, for example, encased in the cover.

[0053] By completely wrapping the at least one pressure pad base element in a cover material, in particular a soft cover material, for example, silicone, not only the above-mentioned advantages in terms of application technology can be achieved, but also the manufacturing of the pressure pad according to the invention is facilitated, because even if there are pressure- bearing areas of the protrusion element, the second base surface of the pressure pad base element, which faces away from the user, i.e. the pressure-bearing surface, can easily be produced as a flat surface; of course, this surface can also have protrusions and / or recesses.

[0054] The protrusions at the edge of the aperture in the vicinity of the protrusion element can be made of a third material, which can be softer or harder than the material of the pressure pad base element.

DETAILED DESCRIPTION

[0102] Figure 1 A lateral cross-section of a basic piece of a pressure pad 10 with its protrusion piece 20 is schematically shown. The basic piece 10 extends in a sheet-like manner and is located in the middle layer, i.e. the basic layer A, of an abstract structure of a three-layer pressure pad. The protrusion piece 20 is connected to the basic piece 10 via a pressure- bearing zone 21. The pressure-bearing zone 21 is located below the basic layer A, i.e. in the pressure-bearing layer B. The pressure-bearing zone 21 borders on one of at least two protrusion zones 22, in which the protrusion piece 20 ends. The protrusion zones 22 are located above the basic layer A, i.e. in the action layer C. The middle, i.e. the basic layer A, is between the action layer C and the pressure-bearing layer B, and can be regarded as the "thickness" of the basic piece 10.

[0103] Figure 2 A back pressure pad 200 of the application is shown. Figure 2 A shows the action face 201 of the basic piece 10 facing the wearer. Figure 2 B shows the pressure-bearing face 202 of the basic piece 10 facing the (optionally present) pressure pad carrier, seen from the back. The back pressure pad has a sheet-like basic piece 10 and a plurality of protrusion pieces 20, 30 distributed over the basic piece 10. Ten of the protrusion pieces are protrusion pieces 20 having only one protrusion zone, while the other six protrusion pieces 30 are protrusion pieces 30 of the application, each having three mutually connected protrusion zones 32. From Figure 4 The exact structure of the protrusion pieces 20, 30 can be seen.

[0104] All the protrusion pieces 20, 30 have in common that their protrusion areas 22, 32 protrude from the action face 201 of the pressure pad base piece 10 and that their pressure receiving areas 21, 31 protrude from the pressure receiving face 202 of the pressure pad base piece 10.

[0105] Figure 3 A perspective view of the back pressure pad according to the present invention is shown. Figure 2 Two other perspectives of the back pressure pad according to the present invention are shown. Figure 3 A shows an oblique view of the action face 201 of the pressure pad base piece 10 facing the wearer. Figure 3 B shows a side view. As can also be seen, the protrusion pieces 20, 30 protrude with their protrusion areas 22, 32 from the action face 201 of the pressure pad base piece 10 and with their pressure receiving areas 21, 31 from the pressure receiving face 202 of the pressure pad base piece 10.

[0106] Figure 4 A perspective view of the back pressure pad according to the present invention is shown. Figure 2 A perspective view of the back pressure pad according to the present invention is shown. Figure 3 A cross-sectional view of the pressure pad base piece 10 of the pressure pad according to the present invention is shown. As can be seen, the protrusion piece 30 has three of its protrusion areas 32 connected to each other and positioned on the protrusion 33. The protrusion piece 30 is connected to the pressure pad base piece 10 via the protrusion areas 32. The protrusion areas 32 are positioned above the action face 201. The protrusion areas 32 are connected to the pressure receiving area 31. The pressure receiving area 31 is positioned below the pressure receiving face 202. The three protrusion areas 32 are connected to each other via the pressure receiving area 31, thus forming a "protrusion nest". The protrusion piece 30 can be made of a softer material than the pressure pad base piece 10.
