Description

  

  <U>Einrichtung für die</U>     Wärmebehandlung   <U>von</U>  <U>menschlichen oder tierischen Körpertei-</U>  <U>len, mit einer elastischen, wasserdich-</U>  <U>ten, beheizbaren Druckbandage</U>    Die Erfindung betrifft eine Einrichtung  für die Wärmebehandlung von menschlichen  oder tierischen Körperteilen, mit einer ela  stischen, wasserdichten, beheizbaren Druck  bandage, welche mindestens ein elastisch  dehnbares elektrisches Widerstandselement  enthält.  



  Die Druckbandage- kann     z.B.    in der physi  kalischen Heiltherapie oder zu     Schlankheits-          und    Schwitzkuren und dergleichen verwendet  werden.  



  Heizkissen oder Wärmematten sind seit  langem in Gebrauch, doch eignen sich alle  bekannten Ausführungen ungenügend als Ban  dagen, die sich der Körperform anpassen  und eng anschmiegen sollen, um damit nebst  der Erwärmung einen gleichmässigen Druck  auf das zu behandelnde Körpergewebe auszu  üben. Durch die bei Heizkissen üblicherwei  se verwendeten Textilien wird trotz Kunst  stoffschutzhüllen keine Wasserdichtigkeit  erreicht. Bei nassen Heizkissen besteht  die Gefahr von Elektrounfällen. Die übli  cherweise in groben Stufen einstellbare  Heizleistung führt leicht zum     Ueberhitzen.     



  Der Erfindung liegt die Aufgabe zugrunde,  eine Einrichtung mit einer elektrisch heiz  baren, elastischen, wasserdichten Druck  bandage zu schaffen.  



  Die erfindungsgemässe Einrichtung ist da  durch gekennzeichnet, dass die Druckbanda  ge einen Körper aus gummielastischem Mate  rial aufweist, in welchem mindestens ein  elastisch dehnbares elektrisches Widerstands  element dicht eingeschlossen befestigt ist,  welches Widerstandselement wenigstens einen       mäanderförmig    gebogenen elektrischen Leiter  enthält.  



  Die Einrichtung kann     ferner    Mittel enthal  ten,     um    die Temperatur des Widerstandsele-         mentes    automatisch auf einem vorgewählten  Wert konstant zu halten.  



  Anhand der Zeichnung wird nachstehend ein  Ausführungsbeispiel der erfindungsgemässen  Einrichtung näher erläutert. In der Zeich  nung zeigen:       Fig.    1 eine Ansicht einer flachgelegten  Druckbandage und       Fig.    2 ein geregeltes Speisegerät der  Einrichtung.  



  Die in     Fig.    1 dargestellte Druckbandage  besitzt einen Körper 1 aus gummielastischem  Material,     z.B.    aus kalt vulkanisiertem Gum  mi. Der Körper 1 kann beispielsweise aus  zwei miteinander verklebten oder zusammen  vulkanisierten Platten bestehen, er kann  aber auch     einstückig    geformt sein. An den  Enden des Körpers 1 sind Klettenverschlüs  se 2 schematisch angedeutet.  



  In dem Körper 1 bzw. zwischen den     beieden     Platten desselben sind elastisch     dehnbaie     elektrische Widerstandsbänder 3 dicht ein-      geschlossen befestigt,     z.B.    festgeklebt  oder eingegossen. Damit die Widerstandsbän  der 3 in Längsrichtung elastisch dehnbar  sind, enthalten sie je wenigstens einen     mä-          anderförmig    gebogenen elektrischen Leiter  4. Vorzugsweise besteht jedes Widerstands  band 3 aus einem Gewebe, dessen Zettelma  terial aus elastischem Garn,     z.B.    aus     "Ly-          cra",    besteht, während das Schussmaterial  den elektrischen Leiter 4 enthält oder dar  aus besteht.

   Dieser Leiter 4 hat dabei  vorzugsweise die Form einer hochflexiblen  Kupferlitze, welche zur Verbesserung der  Haftung im Gewebe umsponnen ist. Ein sol  ches gewebtes Widerstandsband kann eine  Nenndehnung von bis 160 7 aufweisen.  



  Um auch eine Dehnung der Bandage in Quer  richtung zu ermöglichen, kann man den Lei  ter 4 selbst dehnbar ausbilden. Ein solcher  dehnbarer Leiter kann zum Beispiel aus ei  nem von einem Metalldrahtgeflecht oder       -gewirke    umgebenen Kern aus gummielasti  schem Material,     z.B.    Kunststoffelastomer,  bestehen.  



  Ein schematisch angedeutetes     Stromzufüh-          rungskabel    6 ist mechanisch entlastet und  wasserdicht in den Körper 1 eingeführt.  



       Fig.    2 zeigt das Blockschaltbild des elek  tronisch gesteuerten Speisegerätes 7 der  Einrichtung. Das     Stromzuführungskabel    6 ist  in einem Zweig einer     Wheats.tone'schen        Brük-          kenschaltung    8 angeschlossen, so dass die  ser Zweig von den Widerstandsbändern 3       (Fig.    1) gebildet wird. Die Brückenschal  tung 8 wird von einem     Oszillator    9 mit ei  ner Messpannung von 2070 Hz gespeist. Der  elektrische Widerstand der Bänder 3 stellt  ein Mass für die Bandtemperatur dar.. An  einem Brückenwiderstand R lässt sich die  gewünschte Soll-Temperatur einstellen.

   Die       Brückenfehlerspannung    wird in einem selek  tiven     2070-Hz-Verstärker    10 verstärkt und  einem     Phasendiskriminator    11 zugeführt. Das       Gleichstromausgangssignal    des     Phasendiskri-          minators    11 wird in einem Gleichstromver  stärker 12     verstärkt    und einer     Zündwinkel-          Steuerschaltung    13 für eine     Thyristorstufe     14 zugeführt.

   Die     Thyristorstufe    14 steuert  die Heizleistung, die den Widerstandsbän  dern 3 aus einem     50-Hz-Wechselspannungsnetz     über einen Trenntransformator 15, die     Thy-          ristorstufe    14 und das     Stromzuführungskabel     6 zugeführt wird. Bei Gleichgewicht der  Brückenschaltung 8 wird die zugeführte     Heiz-          leistung    null.    Die ebenfalls in     der.Brückenschaltung    8  auftretende     50-Hz-Heizspannung    beeinflusst  die Steuerung nicht, weil die Brückenaus  gangsspannung durch den selektiven Verstär  ker 10 geleitet wird, der auch Oberwellen  der Heizspannung eliminiert.

   Die beschrie  bene Verwendung der Heizbänder 3 selbst als       Temperaturmessfühler    hat den Vorteil, dass  das     Stromzuführungskabel    6 nur zwei Leiter  enthalten muss, dass keine .gesonderten     Tem-          peraturmessfühler        erforderlich    sind und ,  dass tatsächlich genau die Temperatur der  Widerstandsbänder gemessen wird.  



  genau die Temperatur der Widerstandsbänder  gemessen wird.



  <U> Device for the </U> heat treatment <U> of </U> <U> human or animal body parts </U> <U> with an elastic, watertight </U> <U> th , Heatable pressure bandage </U> The invention relates to a device for the heat treatment of human or animal body parts, with an elastic, waterproof, heatable pressure bandage which contains at least one elastically stretchable electrical resistance element.



  The pressure bandage can e.g. be used in physical healing therapy or for slimming and sweating cures and the like.



  Heating pads or heating mats have been in use for a long time, but all known designs are insufficiently suitable as Ban dagen that should adapt to the body shape and cling tightly in order to exert an even pressure on the body tissue to be treated in addition to heating. Due to the textiles usually used in heating pads, water-tightness is not achieved despite plastic protective covers. There is a risk of electrical accidents if the heating pad is wet. The heating power, which is usually adjustable in coarse steps, easily leads to overheating.



  The invention has for its object to provide a device with an electrically heiz ble, elastic, waterproof pressure bandage.



  The device according to the invention is characterized in that the pressure band has a body made of rubber-elastic material, in which at least one elastically stretchable electrical resistance element is tightly enclosed, which resistance element contains at least one meander-shaped electrical conductor.



  The device can also contain means to automatically keep the temperature of the resistance element constant at a preselected value.



  An exemplary embodiment of the device according to the invention is explained in more detail below with reference to the drawing. In the drawing: FIG. 1 shows a view of a flat pressure bandage and FIG. 2 shows a regulated supply device of the device.



  The pressure bandage shown in Fig. 1 has a body 1 made of rubber-elastic material, e.g. made of cold vulcanized rubber. The body 1 can consist, for example, of two plates glued together or vulcanized together, but it can also be formed in one piece. At the ends of the body 1 Klettenverschlüs se 2 are indicated schematically.



  In the body 1 or between the two plates of the same, elastically stretchable electrical resistance strips 3 are tightly enclosed, e.g. glued or cast. So that the resistance bands 3 are elastically stretchable in the longitudinal direction, they each contain at least one meander-shaped electrical conductor 4. Each resistance band 3 preferably consists of a fabric, the label material of which is made of elastic yarn, e.g. from "Lycra", while the weft material contains the electrical conductor 4 or consists of it.

   This conductor 4 preferably has the form of a highly flexible copper braid, which is wrapped in order to improve the adhesion in the fabric. Such a woven resistance band can have a nominal elongation of up to 160 7.



  In order to allow the bandage to stretch in the transverse direction, the Lei ter 4 itself can be made stretchable. Such a stretchable conductor can, for example, consist of a core of rubber-elastic material surrounded by a metal wire mesh or knitted fabric, e.g. Plastic elastomer.



  A schematically indicated power supply cable 6 is mechanically relieved and inserted into the body 1 in a watertight manner.



       Fig. 2 shows the block diagram of the electronically controlled power supply 7 of the device. The power supply cable 6 is connected in a branch of a Wheats.tone's bridge circuit 8, so that this branch is formed by the resistance bands 3 (FIG. 1). The bridge circuit 8 is fed by an oscillator 9 with a measuring voltage of 2070 Hz. The electrical resistance of the strips 3 represents a measure of the strip temperature. The desired target temperature can be set on a bridge resistor R.

   The bridge fault voltage is amplified in a selective 2070 Hz amplifier 10 and fed to a phase discriminator 11. The direct current output signal of the phase discriminator 11 is amplified in a direct current amplifier 12 and fed to an ignition angle control circuit 13 for a thyristor stage 14.

   The thyristor stage 14 controls the heating power which is supplied to the resistance bands 3 from a 50 Hz AC voltage network via an isolating transformer 15, the thyristor stage 14 and the power supply cable 6. When the bridge circuit 8 is in equilibrium, the heating power supplied becomes zero. The 50 Hz heating voltage also occurring in the bridge circuit 8 does not affect the control, because the bridge output voltage is passed through the selective amplifier 10, which also eliminates harmonics of the heating voltage.

   The described use of the heating strips 3 themselves as temperature sensors has the advantage that the power supply cable 6 only has to contain two conductors, that no separate temperature sensors are required and that the temperature of the resistance strips is actually measured precisely.



  precisely the temperature of the resistance bands is measured.
