Definitions
- the invention relates to thermal products for single treatment and / or as self-therapy in acute, recurrent and / or chronic pain conditions comprising annularly arranged heat-generating materials.
- Thermal products for single treatment and / or as self-therapy for acute, recurrent and / or chronic pain in muscles and / or joints, stiffness, nerve pain, rheumatism, menstrual pain, etc. have enjoyed increasing popularity in Europe, North America and Australia since the 1990s Users and generate constantly growing sales at the manufacturers.
- the HANSAPLAST heat therapy ped is mentioned here.
- JIS Japanese Industrial Standard
- Substance mixtures can e.g. Charcoal chips, humectants, agglomeration aids, binders, metal salts, organic or inorganic fillers and many other substances may be included to adjust the desired end product properties.
- Charcoal chips e.g. Charcoal chips, humectants, agglomeration aids, binders, metal salts, organic or inorganic fillers and many other substances may be included to adjust the desired end product properties.
- heat cells segmented incorporated. These heat cells are usually formed by a defined amount
- heat-generating substance mixture is completely enclosed by two interconnected polymer films, wherein at least one polymer film defined must be oxygen-permeable.
- the heat cells may also be in the form of a closed tube, tube or bag.
- Heat generating compositions may also be applied to thermoforming sheets and then sealed (e.g., EP 1782787).
- these heat cells can then be laminated in different sizes, numbers and configurations between two, e.g. bonded by gluing or fusion, bonded carrier substrates, wherein the carrier material adjacent to the oxygen-permeable polymer film of the heat cell must also be oxygen permeable.
- carrier substrates may be films, fabrics, nonwovens, gauze or any other suitable carrier substrate for application to the human body.
- the heat pads are self-adhesive on the side facing the skin later.
- a corresponding skin-friendly adhesive is applied to the carrier substrate.
- the adhesive application can be full-surface or partial, e.g.
- Adhesives are a variety of different adhesives known in the art, e.g. Acrylate, synthetic rubber or
- the heat pads can also be stuck to the inside of skin-tight clothing parts such as T-shirts or undershirts.
- the forcibly existing heat-insulating air cushion between the skin and the heat pad reduces a good heat transfer from the heat pad to the body.
- heat pads self-adhesive, but to attach to the application in prefabricated pockets or recesses of specially made for this purpose belts, hose bandages, camisole, vest or similar fixing aids on the body.
- the fixation of heat pads by means of patches or medical tapes (medical tapes) is known.
- the corresponding heat cells are fixed in a laminate between a skin-facing and a skin-facing carrier substrate.
- the heat pads in the heat pad or heat belt are activated by contact with oxygen in the air, the heat pads must be in air-impermeable packaging immediately after production be sealed. Only then is the heat pad removed from the packaging and the oxygen contact then initiates the exothermic process (oxidation of the iron contained in the heat-generating mixture).
- the heat generation after 30 min should be so advanced that an application temperature on the skin between 40 and 45 ° C is reached.
- the disadvantage of this type of heat pads is the fact that the powdery substance mixture in the heat cells during the heat generation process before the application blocks together in total surface to form a stiff solid (clumped, sintered together).
- the heat cells are thus no longer suitable for a moving user to follow the changing skin surface contours, it can thereby even certain
- such a stiff heat cells can cause the heat pads in and / or movements of the user no longer have full skin surface contact and thus not the full curative heat output of the product is transferred to the user.
- hinge axes have the disadvantage that the range of heat cells of the heat pad must be supported by rigid or semi-rigid materials to twist or
- heat pads for certain applications.
- a popular form are heat belts for lumbar use, as disclosed, for example, in US1996 / 0777830.
- Air layer between product and skin results. Since air is a very good heat insulator, this leads to a reduction in the healing effect of the heat products.
- PCMs phase-changing material
- PCMs are substances that can store or release large amounts of energy when melting or solidifying at a certain temperature. This makes PCMs a latent heat storage and a suitable material to significantly reduce the effects of possible local overheating of heat cells for human application.
- PCMs When PCMs reach the temperature at which they change phase, e.g. the melting temperature, they absorb large amounts of heat energy at a nearly constant temperature until all the material has melted. When the ambient temperature drops again, the PCMs solidify and release the stored energy.
- Suitable PCM materials for use in heat cells are e.g. Alkanes having 14 to 30 carbon atoms or mixtures of these alkanes. Corresponding materials and their use are e.g. disclosed in US 2012/0150268.
- PCMs combine during melting with the remaining components of the heat-generating mixture of a heat cell and thus also lock into a stiff overall structure.
- microencapsulated PCMs are known to those skilled in the art for heat and cooling pads of the prior art (e.g., US 2003/0109910 and CA 2289971).
- the microencapsulated PCM is embedded in solutions or gels, which must be heated in a microwave or water bath before use.
- Heat cells are suitable, are not known.
- the heat cells have an annular shape.
- ring-shaped is a crosshair-like shape, in which at least two concentrically arranged rings, ellipsoids or rectangles are connected to an object by means of connecting structures.
- FIG. 1 shows an inventive annular structure 1 of two concentrically arranged rings 2, 3, which span around a point located in the center point 4 and are bridged over the orthogonal to each other arranged compounds 5, 6.
- This structural unit is referred to in the context of the invention as a crosshair arrangement or crosshairs.
- the heat pads according to the invention have one or more heat cells which contain heat-generating mixtures of substances which have microencapsulated PCMs.
- PCMs Commercially available encapsulated PCMs are e.g. under the trade name Lurapret® or Micronal® at BASF.
- Thermal pads of the invention can be used for direct fixation on the treated
- Concentric rings have the potential to cushion tensile force due to their curved geometry. In an annular arrangement at most until the curved inner circumference of a ring between two opposing force action points to a straight line or a brittle material breaks before. The absolute inner diameter of the ring attacked by a force thus determines the reduction of the rigidity of a heat cell made in this way.
- the rigidity of the end products is reduced at annular distinct heat cells with the size of the heat cells.
- the size of the heat cells can be determined by the circumference and by the number of crosshair arrangements.
- the reticule-shaped heat cell can be understood in the basic form as two or more concentrically arranged rings of different diameters with an overlying grid structure.
- the heat cell according to the invention has two
- rings are also to be understood as meaning closed ring-shaped structures such as ellipses, triangles, rectangles or modifications thereof.
- a structure which corresponds to the outline of a four-leaf clover ( Figure 5)
- a self-adhesive or non-adhesive heat product according to the invention analogous to JIS S 4100 can contain a crosshair-shaped heat cell or any number of individual or interconnected crosshair-shaped heat cells, whereby a single large heat cell with cross-haired subunits is formed by joining two or more crosshair-shaped heat cells (FIG. 2).
- the reticule-shaped heat cells do not have to be exactly circular, but may also be oval, ellipsoidal, square or rectangular-oblong. Especially for large-area heat products for

- the widths of circles on the x- and y-axis of a flat projected district heating cell may be different, if necessary. Also alternately. This is a good compensation option for a homogeneous user product, especially in large-area, rectangular-oblong or oval circles as heat cells.
- a particular advantage of the reticulate shape of the heat cells is the fact that comparatively narrow circles / lines, in contrast to total area heat cells have a significantly lower resistance to breakage. If a force is exerted on the heat cell when applied by movement of the user, the circles / lines break much more easily along the surface of the oxidized mixture due to the smaller width of the composite material
- Preferred distances between the circles or lines are within the total area of a cross hair assembly 0.1 cm to 5 cm, more preferably 0.2 cm to 4 cm and most preferably 0.2 cm to 3 cm.
- the spacings in the configurations are to be selected so that the thermal radiation of individual circles / lines overlap in the skin of the user as possible to give a homogeneous feeling of warmth over the entire treatment surface.

- these heat pads contain four longitudinally one behind the other
- heat pads are made in the form of a concave on the sides and rounded at the corners triangle.
- FIG. 3 shows by way of example a 'triangular' heat pad with four separate heat cells, with a crosshair-shaped heat cell in the center, which is composed of three heat cells in the geometry of FIG.

- Heat pads according to the invention preferably contain centrally in the center a heat cell with the geometry of a reticule, which is connected at the end point of each cross line with a further heat cell centered in the direction of the triangle vertices in the form of a reticule (FIG. 3).
- Thermal pads according to the invention in the form of a heat belt preferably contain 1 to 8, more preferably 2 to 4, optionally crosshairs interconnected crosshair-shaped heat cells.
- the heat cells are preferably distributed over a heat-emitting base of less than 25 cm by 35 cm and can be arranged both side by side and one above the other.
- one or more non-adhesive heat pads are placed in suitably prefabricated pockets.
- the heat belt has belt elements on both sides, which may consist of a multiplicity of materials and shapes familiar to the person skilled in the art and of different elasticity, and terminate on the longitudinal axes in a common closure system. This preferably exists
- crosshair-shaped heat cells may preferably be bonded in a laminate-like manner between longitudinally elastic, particularly preferably bi-elastic, support materials.
- Crosshair (s) heat cell (s) is arranged with its maximum diameter in the direction of the elasticity of the support materials / are.
- Suitable longitudinally or bi-elastic carrier materials are commercially available in a variety of ways.

- thermoplastic polyurethanes having a basis weight of 75 g / m 2 and a longitudinal extensibility of 300% and a transverse extensibility of 330%.
- Suitable support materials for heat cells according to the invention can be found on
- thermal insulation reduces the release of heat into the surrounding space, thereby saving heat generating materials in the cells and reducing the overall weight of the final product.
- the thermal insulation of the supports can be produced in a variety of ways, e.g. by metal foil coatings or by incorporation of natural residues from the Internalschalenetzarbeitung. Products using the latter technology are e.g. commercially available under the name NILIT® Heat.
- the described principle is also inversely applicable, in which one adds to the heat product correspondingly adhering conditionally oxygen permeable material layers of the
- Heat product can be attached to reduce the supply of oxygen, which in turn leads to a reduced total temperature and a prolonged period of use.
- a further advantageous possibility for better utilization or release of the thermal energy of cells according to the invention consists in the addition of phase-changing materials (PCMs) to the support materials, but particularly preferably directly as a component of the exothermic
- Particularly preferred for use in exothermic heat mixtures in cross-hair arrangement according to the invention are encapsulated PCMs whose capsule diameter is smaller than the thickness of the crosshair-shaped heat cells and advantageously 0.5 to 1, 5 mm. Since the capsules retain their external shape during the temperature transitions of the PCMs, they do not associate with the reacting and slow-curing heat mixture and thus, by virtue of their size, can act as an inherent force to the user by movement as inherent joints in the heating circuits / lines thereby provide a significantly reduced rigidity when applied to the body.
- Heat cells a lenticular, semi-convex layer of thermally conductive polymers is applied.
- This lenticular layer may be in the surface extent both circular, as well as ellipsoidal or oval or irregular.
- preference is given to polymer layers of silicone since silicones have very good elasticity and heat conduction properties (eg silicone resins at RT of 0.15 to 0.32 W / mK), but in particular also a comparatively good compression behavior of 15% to 30%.
- Lenticular silicone layers with a thickness of 0.01 cm to 2.5 cm and a maximum diameter of 2 cm to 20 cm are therefore well suited to ensure the full-surface skin contact of the exothermic heat cells for optimum heat transfer even during movement of the user.
- This layer is particularly preferably made from silicone polymers having a Shore hardness of less than or equal to 50 Shore A.
- Thermal pads according to the invention using reticule-shaped heat cells can be provided with thermal displays. Since the subjective heat sensation of the user can usually be reduced with habituation effects with increasing duration of use and the heat product is thereby removed by the user before the end of the indicated treatment time, optical control of the temperature is advantageous. Corresponding indicators which can visualize the temperature by means of chemical color reactors are e.g. from US
- Thermal pads according to the invention may e.g. Also with hyperemic agents such as anti-inflammatory drugs and / or analgesics, such as natural agents of cayenne pepper or synthetic agents such as nonivamide, nicotinic acid derivatives, preferably bencylnicotinate or propyl nicotinate, are equipped.

- the essential oils can be incorporated not only into the wearer-facing carrier substrate, but in particular in the skin-facing away
- Carrier substrate Particularly preferably, the active ingredients are present in encapsulated form.
- Essential oils are plant-derived concentrates that are used as natural raw materials mainly in the perfume and food industry and consist more or less of volatile compounds. As examples of these compounds may be mentioned 1,8-cineole, limonene, menthol, borneol and camphor. Often the term essential oils is used for the volatile ingredients still contained in the plants. In the real sense, however, etheric oils are understood to mean mixtures of volatile ones
- Essential oils consist exclusively of volatile components whose boiling points are generally between 150 and 300 ° C. They contain predominantly hydrocarbons or monofunctional compounds such as aldehydes, alcohols, esters, ethers and ketones.
