Definitions
- the invention relates to a heating bandage for the human and/or animal body, comprising a textile, woven base material or base material made of knitted goods, comprising non-conductive threads and conductive threads.
- A1 which describes a conductive circular textile fabric that is pressed flat and embedded in a foam.
- heat or heating bandages or textiles are known, e.g. from the sports sector, e.g. from Lenz Products, Schwarzach, Germany, with heat conductors being applied to a type of bandage, e.g. in the form of a kidney belt.
- the conductive threads which at least partially serve to generate heat, are introduced into the base material during its production process.
- a heating bandage can be provided that can be produced in almost any dimensions, both in terms of length and width.
- the bandage is easier to manufacture because the bandages are used for heating or heat generation
- Threads are immediately introduced into the woven or knitted fabric and no additional further steps, such as the following Pulling in or applying and eg gluing or otherwise fixing heating filaments or heating wires is necessary. This also eliminates the risk of failures that can result from loosening the attachment points between the woven or knitted fabric and conductive threads, etc.
- Base material made of knitwear is to be understood and includes both warp-knitted and knitted base materials. It is particularly preferred if the heating bandage has a length that is dimensioned such that the heating bandage can be placed once around the body area to be heated. Alternatively, however, it is also conceivable to provide a heating bandage that can be placed or wrapped several times around a body region to be heated and fixed there.
- the width of the heating bandage is preferably 4-30 cm, in particular 4-20 cm and preferably 5-10 cm. A width of 5 cm or 10 cm is particularly preferred.
- the bandage has a width of less than or equal to 20 cm and more preferably less than or equal to 10 cm.
- the length of the heating bandage can preferably be between 5 and 100 cm, in particular 10 and 70 cm.
- the heating bandage particularly preferably has a length of 10 cm to 50 cm, in particular 10 to 30 cm. The length is in the unstretched state.
- the length of the heating bandage can vary depending on the application.
- the heating bandage can preferably once around the be wrapped around the part of the body to be treated, but in principle several wraps/tours are also possible. For this purpose it can be provided that insulated electrically conductive yarns are used or subsequently insulation is applied to the base material of the heating bandage, for example by a
- the base material of the heating bandage can also be bordered by additional textile layers, e.g. a conventional bandage.
- the conductive threads serve to generate heat and these are drawn in as weft and/or warp threads.
- the electrically conductive threads in the case of knitted fabrics, in particular crocheted or knitted fabrics, provision can be made for the electrically conductive threads to be introduced into the knitted fabric as an additional weft thread during its manufacture.
- the conductive threads only form part of the warp or weft threads.
- a conductive thread is inserted as a weft, with a spacing being created between each weft insertion of conductive thread and the wefts made of non-conductive threads in between.
- this additional weft insertion may be guided by hand, but mechanical guidance is preferred.
- the thread is carried along the selvage between the insertions when the non-conductive yarns are being inserted. An S-shaped curve then develops in the conductive weft thread in the bandage.
- This S-shaped curve can spread over the extend over the entire width of the woven base material or the knitted fabric base material or only over a part thereof. If the conductive weft thread extends only partially across the width of the base material, it or these threads can preferably be arranged in the middle area of the base material. However, an arrangement in the edge area, ie in the direction of the selvedges running in the longitudinal direction, is also possible. In principle, several conductive weft threads can also be drawn in.
- conductive warp threads are provided, they can be arranged in a sequence with non-conductive warp threads, for example two non-conductive warp threads can be used between two conductive warp threads. Furthermore, it is particularly preferred to introduce elastic threads and in particular elastic conductive threads into the woven or knitted fabric.
- the non-conductive threads can also be designed to be elastic or at least partially elastic. The elasticity can be achieved via elastomeric threads, which can be wrapped with a conductive material in order to provide conductivity, in particular windings made of polyester or enameled copper wire can be provided, the core of which consists in particular of elastane.
- cotton-elastic threads can also be used, which have been appropriately treated to produce elasticity.
- the extensibility of The heating bandage is preferably in the range of up to 200%, in particular up to 100% and particularly preferably between 10-20%, provided an elastic design is selected.
- the stretchability is measured according to DIN EN ISO 13934-1:2013
- Cotton is particularly preferred as threads for the non-conductive threads, since cotton has good skin compatibility, provided the desired elastic properties of the bandage permit this.
- Synthetic yarns e.g. from
- Polyamide or polyester with a silver coating threads made of polyester and enameled copper wire and elastic covered yarns made of elastane with windings made of polyester and enameled copper wire.
- combinations of the conductive and non-conductive threads mentioned are also possible.
- conductive threads can be used, in which a textile thread, e.g. a polyester or polyamide thread, has been twisted with a wire.
- the threads can be insulated or non-insulated yarns, with insulated yarns allowing the bandage to be wrapped several times, even overlapping one another.
- the threads can also be selected based on their resistance. It can be provided that in the area of heat emission
- thread is to be understood here synonymously with yarn.
- thread can also be understood to mean groups of threads or bundles of threads, i.e. threads combined into several, which have the same course as warp or weft threads. These can be designed as twisted yarns or as a sheet of threads running essentially parallel.
- the heating bandages are preferably designed as narrow textiles.
- Such narrow textiles can be produced in the form of fabrics, for example, on a shuttle loom or a needle ribbon loom. If production takes place in series, the weft thread, in particular a separate weft thread, can no longer be fed in as a conductive thread manually, but via a weft color control.
- a jacquard machine can be used as a device. In the case of small series or individual pieces, manual feeding of a conductive weft thread is also conceivable.
- a gallon crochet machine for example, can be used to produce a narrow textile as a knitted fabric.
- conductive threads are used as warp and/or weft threads
- threads that differ in particular in terms of material and/or resistance can be selected.
- woven electrodes are provided on the longitudinally spaced end regions of the heating bandage, which in particular comprise electrically conductive weft threads, a different material or a different Resistance to be selected versus conductive threads in the area between the end areas.
- the heating bandage has woven electrodes at its end regions, which can extend in the longitudinal direction over up to one third of the length depending on the length of the bandages, but preferably have less extension in the longitudinal direction, which can be contacted via electrical lines.
- the conductive threads for heat generation can then only extend between the two end areas, eg in the form of weft threads or, alternatively or additionally, eg by conductive warp threads, with conductive warp threads for heat generation being preferred, extend into the end areas. It can be provided that threads that form the woven electrodes or are used in some other way for electrical contacting have a lower resistance than threads that are used to generate heat.
- both conductive weft threads especially in the area of woven electrodes, and the conductive warp threads, which can run over the entire length of the fabric, the current is conducted through the where the conductive warp and the conductive weft touch entire bandage.
- a configuration in which conductive warp threads for heat generation and conductive weft threads are provided in the woven electrodes is particularly preferred.
- the threads that provide the heat can be both weft threads and warp threads.
- the threads for the electrical contacting are essentially provided as weft threads in the end areas.
- weft threads for electrical contacting or for providing heat can also be provided, which do not extend over the entire width of the base material.
- the thread or threads for providing the heat output can also only extend over a central area between the two longitudinal side edges or lateral areas of the bandage. This can be the case in particular with a knitted fabric that is produced on a galloon crochet machine.
- Conductive threads with a resistance of 3-100 W/m can be used as a suitable resistor, for example for the electrical supply lines or woven electrodes.
- the resistance can be up to 500 W/m. If yarns with different resistances are used, it can be advantageous to use high-impedance yarns for generating and conducting heat and low-impedance yarns for conducting electricity. The difference in resistance is more important than the actual resistance. This is to ensure that in the areas with lower resistance no heat generation takes place, but only a transmission of the current in order to achieve a heating effect only in the areas with higher resistance.
- the bandage is connected to electronics and/or a power supply via the electrically conductive threads or at least some of them, in particular via the woven electrodes.
- the power supply and / or the electronics can be mobile, ie batteries or rechargeable batteries or another
- Power storage carried out, which are included in a housing.
- the housing can then be accommodated, for example, in a pocket that is provided or can be attached to the bandage.
- the housing can also have a clip, a buckle or
- the electronics or circuit may include a printed circuit board, a microcontroller, DC/DC converters, a transistor, e.g. a MOSFET (Metal-Oxide Semiconductor Field-Effect Transistor), and/or resistors, the
- the housing can have dimensions of up to 10 cm in length, in particular up to 7 cm in length, in particular up to 5 cm in length.
- the width can be up to 7 cm, in particular up to 5 cm.
- the height of the housing can be up to 5 cm, in particular up to 3 cm.
- the weight of the electronics including the housing can be up to 50g, in particular up to 30g and in particular up to 25g. In this case, small dimensions and weights are desired because of mobility.
- the electrical connection of electronics and/or a power supply to the woven electrodes or other electrical connections on the heating bandage can be made, for example, via snap fasteners in particular.
- detachable or non-detachable connections are also conceivable, such as plug connections or crimp connections, which can be riveted to the heating bandage, for example.
- standard non-detachable connections are also conceivable.
- the achievable and/or desired temperature of the heating bandage, to which it should heat up is 25-45°C, in particular 28-42°C.
- the bandage has a temperature sensor.
- This can likewise be permanently or detachably connected or connectable to the bandage.
- the temperature sensor can in particular interact with a temperature controller and control and/or regulate the temperature either on one Allow default or a desired/selectable value.
- the electronics have a Bluetooth interface so that the electronics can be controlled, for example, via a remote control, e.g. a mobile phone.
- a remote control e.g. a mobile phone.
- the heating bandage can be switched on and off and, if necessary, the
- Temperature setting done in this way.
- a mobile phone can act as a control unit via an app.
- a user can then set the temperature interactively via their smartphone.
- the base material is provided as a fabric and electrically conductive warp threads are inserted into the base material, which alternate with non-conductive warp threads in a predetermined sequence.
- a conductive warp thread can follow every two non-conductive threads.
- an electrically conductive weft thread is woven into the end areas of the bandage, with preferably all weft threads in the end areas of the heating bandage being electrically conductive. The energy is fed into the bandage through these electrically conductive weft threads.
- the conductive warp threads have a greater resistance than those in the end areas of the bandage to form a woven one
- Electrode arranged electrically conductive weft threads are preferably made of the same material, in particular silver-coated Polyamide yarns, like the electrically conductive warp threads. In particular, only two different electrically conductive threads are used.
- Another preferred embodiment of the invention relates to a design in which the warp threads are electrically non-conductive and one or more electrically conductive weft threads are drawn into the fabric in addition to the non-conductive weft threads and are carried between the wefts on the selvage. The electrical contacting at the end areas can take place via woven electrodes or in some other way.
- a further preferred variant provides a knitted fabric as the base material, this being produced by knitting or warp knitting.
- a warp knitting machine e.g. a gallon crochet machine, creates an additional warp knitting machine.
- the heating bandage can be part of a heatable bandage, which consists of the heating bandage and a base bandage, with the base bandage not being heatable.
- the heating bandage and the base bandage can be firmly connected to each other to form the heatable bandage, in particular the base bandage can connect to the heating bandage in one or both directions.
- the base bandage can also extend over the heating bandage in the longitudinal direction.
- the width of the base bandage can correspond to the width of the heating bandage. In particular, if the base bandage extends over the heating bandage in the longitudinal direction, it can also be wider or narrower.
- the length of the basic bandage is arbitrary and can be adjusted depending on the application.
- the heating bandage can also be accommodated between two or more layers of a base bandage.

- Woven electrodes 16a and 16b are again provided in the region of the two end regions 14, the electrodes 16a,b and the entire base material 12 being produced as woven material in this variant.
- a conductive yarn is provided as a weft 50, this yarn having in particular a low resistance of, for example, 40 W/m.
- the warp threads 52 which extend through the woven electrodes 16a, 16b and the area in between, are also partly conductive threads 54 with a high resistance up to 500 W/m, alternating with non-conductive warp threads made of cotton 56 are arranged.
- One conductive warp thread 54 and two cotton warp threads 56 are alternately provided.
- a conductive warp thread 54 follows more or fewer than two non-conductive cotton warp threads 56 .
- a non-conductive cotton thread 58 is provided as a weft thread in the area between the woven electrodes 16a and 16b.
- conductive yarns 50 and/or 54 for example, silver-coated polyamide or polyester yarns, as well as elastic wrapped yarns with a core made of elastane and windings made of polyester and enamelled copper wire, can be considered.
- Silver-coated polyamide yarns which can differ in terms of their resistance, are particularly preferred here.
- the latter is highly conductive and is therefore the preferred choice for manufacturing the woven electrodes. Due to the crossing points of the two conductive yarns in the area of the electrodes, where the conductive warp 52 and the conductive weft touch, the current is conducted through the entire bandage.
- the heating bandage 10 according to FIG. 2 was woven on a ribbon loom.
- a further embodiment is now shown in Figure 3 and is also woven on a ribbon loom.
- the tissue as such is not conductive here.
- either woven electrodes can be provided again, as in FIG.
- a conductive thread 65 is also inserted in the weft, but not with each weft insertion, but in such a way that there is a distance between each weft insertion of the conductive yarn 65.
- the wefts 63 in between are continued regularly and inserted through a cotton yarn.
- the conductive yarn 65 is therefore located in the weft in addition to the actual weft insertion 63 made of cotton and is preferably also threaded in by machine or, less preferably, by hand. If the conductive thread is not being fed in, it is carried along along the selvedge 67 . This creates an S-shaped curve within the bandage. In this way, weft thread control can be simulated. Alternatively, automated production without canine intervention is also possible.
- the warp threads are only provided with the reference number 61 here.
- the regular cotton wefts are provided with the reference number 63 and the additional weft insertion made of electrically conductive yarn with the reference number 65.
- the reference number 67 designates the area of the lateral guide on the selvedge. They are different Configurations are possible, for example with a conductive thread 65 or with two conductive threads 65, which can be guided as a double thread.
- the conductive threads can be introduced in such a way that they each have a distance of one or two centimeters between the individual conductive weft insertions 65 . Two or more of the conductive weft threads can also be inserted, which are each guided in an S-curve on the selvedge and in the fabric.
- the resistance can be selected differently.
- Advantageous resistances can be 4.3 W/m or even 9 W/m.
- Threads can be used in which a textile thread, e.g. a polyester or polyamide thread, has been twisted with a wire.
- FIG. 4 A further alternative design of the heating bandage is shown in FIG. 4.
- a conductive thread 72 is also carried along as a weft insertion.
- the production of the base material 12 takes place via a
- Warp knitting machine so that the base material 12 is a knitted fabric.
- the conductive thread 72 here again a hybrid thread with preferably 9 W/m, is carried along as weft insertion.
- a partial weft insertion is now provided, which does not lead over the entire width, ie from the left to the right edge of the knitted fabric, but instead is only entered in the middle field.
- the conductive thread 72 runs in the middle third, which makes up about 20 of 60 rows 74 of stitches. In principle, however, entries over the entire width or a smaller width are also possible. In the present case, it runs lengthwise along about 10 stitches before it is inserted again.
- the thread 72 is enclosed by the connection of the stitches of a wale and integrated in this way into the knitted fabric.
- FIG. 5 now describes an elastic version of the design from FIG. Active feeding of the warp threads is advantageous when processing elastic yarns.
- a conductive elastic wrapped yarn is used here as well as a conductive warp yarn 82.
- the conductive weft yarn 84 in the area of the woven electrodes 16a and 16b is non-elastic.
- a low-impedance yarn is inserted as weft 84 at the beginning and at the end in order to create woven electrodes 16a,b.
- a high-impedance yarn 82 is part of the warp and runs longitudinally through the bandage 10.
- Other non-conductive warp threads are identified by the reference numeral 81.
- the electronics which are not shown here, are in turn located on a printed circuit board, which is arranged in a housing as in FIG.
- a feedback loop as described in relation to FIG. 1, enables temperature regulation that is programmed into the program of the microcontroller.
- the heating bandage 10 can be supplied with power via a power bank, for example.
- crimp connectors being riveted to the bandage 10, at the other end of which a connecting cable is plugged.
- a heating bandage 10 is created that offers advantages in production because additional work steps for applying or inserting the conductive threads can be omitted and at the same time enables mobile use.
