Description

DISPOSITIF A USAGE MEDICAL UTILISANT UN VOLUME LIQUIDE POUR LA PROPAGATION D'ONDES THERAPEUTIQUES MEDICAL DEVICE USING A LIQUID VOLUME FOR THE PROPAGATION OF THERAPEUTIC WAVES
La présente invention a trait à un dispositif permettant l'émis¬ sion d'ondes électriques et/ou magnétiques et/ou électromagnétiques dans un volume liquide pour une application biologique. Les traitements par ondes électriques, magnétiques ou électro- magnétiques sont réalisés actuellement à partir d'appareils individuels ne permettant l'application que d'un seul type d'émission sur une zone réceptrice. Chaque appareil possédant une tête d'émission accordée sur leur émetteur se trouve limité quant à la surface à traiter. Toutes les antennes émettrices sont, par sécurité, isolées et jamais en contact complet avec le patient, une dispersion et une atténuation de l'émission apparaissent au contact de l'air existant entre l'émetteur et le récepteur. Le dispositif selon l'invention permet de remédier à ces incon¬ vénients. Il est essentiellement caractérisé par un ou des émetteurs d'ondes électriques et/ou magnétiques et/ou électromagnétiques et un volume liquide dont le contenant en matière isolante élec¬ triquement est de forme adaptée au traitement. Chaque générateur a sa partie émettrice soit moulée dans la matière, soit en contact avec la face externe du contenant. L'action des différents émetteurs utilisés dans ce dispositif est connue et très couramment utilisée en électrothérapie. Le but de la présente invention est de regrouper par l'intermé¬ diaire d'un volume liquide des différentes actions des générateurs en présence et parfaire à un meilleur rendement par un contact complet des zones à traiter.The present invention relates to a device allowing the emission of electric and / or magnetic and / or electromagnetic waves in a liquid volume for a biological application. The treatments by electric, magnetic or electromagnetic waves are currently carried out from individual devices allowing the application of only one type of emission on a receiving area. Each device having a transmission head tuned to their transmitter is limited as to the surface to be treated. All transmitting antennas are, for safety, isolated and never in complete contact with the patient, a dispersion and an attenuation of the emission appear in contact with the air existing between the transmitter and the receiver. The device according to the invention overcomes these drawbacks. It is essentially characterized by one or more emitters of electric and / or magnetic and / or electromagnetic waves and a liquid volume whose container made of electrically insulating material is of a shape suitable for treatment. Each generator has its emitting part either molded in the material, or in contact with the external face of the container. The action of the different transmitters used in this device is known and very commonly used in electrotherapy. The object of the present invention is to group together, through a liquid volume, the various actions of the generators present and to improve the performance by better contact with the areas to be treated.
Le dispositif préconisé offre l'avantage par l'immersion dans un liquide ou par contact direct avec le contenant des zones à traiter d'avoir une action thérapeutique simultanée sur l'en¬ semble des parties sans dispersion ni atténuation de l'émission dans l'air. Plusieurs générateurs d'émission différente peuvent être employés alternativement ou simultanément. Le liquide utilisé se comporte alors en conducteur d'ondes quelle que soit la fréquence de l'émission émise. Les zones traitées sont complètement exposées aux diverses ondes thérapeutiques dans des conditions supérieures à celles données par les appareils actuels. On peut ainsi noter : - La possibilité d' un traitement simultané d 'ondes électriques , magnétiques et électromagnétiques.The recommended device offers the advantage, by immersion in a liquid or by direct contact with the container of the areas to be treated, of having a simultaneous therapeutic action on the whole of the parts without dispersion or attenuation of the emission in the 'air. Several different emission generators can be used alternately or simultaneously. The liquid used then behaves as a wave conductor whatever the frequency of the emission emitted. The treated areas are completely exposed to the various therapeutic waves under conditions superior to those given by current devices. We can thus note: - The possibility of simultaneous processing of electric, magnetic and electromagnetic waves.
- Un rendement supérieur des émissions.- Higher emission performance.
- La multiplicité des zones traitées. - Une action thérapeutique sur toutes surfaces.- The multiplicity of areas treated. - A therapeutic action on all surfaces.
Pour mieux comprendre le principe de cette invention on va en décrire des exemples de réalisation , étant bien entendu que ceux- ci ne sont pas limitatifs quant à leur mode de mise en oeuvre et aux applications qu ' on peut en faire. - Planche 1/2 : La figure 1 représente en coupe le traitement d 'un patient par immersion dans de l'eau. Deux générateurs d 'émission différente ont leur tête émettrice (A) et ( B) moulées dans la coque (1) en polyester du contenant. La figure 2 représente en coupe le traitement d' un patient par contact extérieur avec le contenant du volume liquide. A la coque ( 1) en polyester on a rajouté un support souple (2) type caout¬ chouc de manière à isoler de l ' eau tout contact extérieur et d ' épouser au mieux les zones traitées. Les figures 3 et 4 représentent en coupe des traitements par immersion de membres supérieurs et inférieurs.To better understand the principle of this invention, we will describe embodiments thereof, it being understood that these are not limiting as to their mode of implementation and to the applications that can be made of them. - Plate 1/2: Figure 1 shows in section the treatment of a patient by immersion in water. Two different emission generators have their emitting heads (A) and (B) molded into the polyester shell (1) of the container. FIG. 2 represents in section the treatment of a patient by external contact with the container of the liquid volume. To the shell (1) made of polyester, a flexible support (2) of rubber type has been added so as to isolate any external contact from the water and to marry the treated areas as well as possible. Figures 3 and 4 show in section treatments by immersion of upper and lower limbs.
La figure 5 représente en coupe le traitement par contact exté¬ rieur avec un contenant entièrement souple type caoutchouc (2) et un générateur (A) moulé.FIG. 5 represents in section the treatment by external contact with a completely flexible rubber type container (2) and a molded generator (A).
- Planche 2/2 : 11 est décrit ici un circuit électrique pouvant alimenter notre dispositif. Le générateur est un émetteur h.f piloté par quartz nous donnant un signal rectangulaire réglable en largeur, amplitude et fréquence pulsatoire.- Plate 2/2: 11 is described here an electrical circuit which can supply our device. The generator is a h.f transmitter controlled by quartz giving us a rectangular signal adjustable in width, amplitude and pulsating frequency.
La fréquence pulsatoire est sélectionnée par un commutateur (11 ) qui agit sur un circuit intégré (12) type 7Λ00. La largeur du signal est obtenue par un circuit (3) type 7-+121. La haute fréquence est réalisée à partir du quartz (4) suivi d' un circuit amplificateur. L 'étage final (5) regroupe le signal de largeur et fréquence choisie, la haute fréquence et venant du commutateur (6) la sélection de puissance. L 'émission se fait dans le volume liquide (7 ) par l ' intermédiaire de l' antenne (8) .The pulsating frequency is selected by a switch (11) which acts on an integrated circuit (12) type 7Λ00. The signal width is obtained by a circuit (3) type 7- + 121. The high frequency is made from quartz (4) followed by an amplifier circuit. The final stage (5) groups the signal of selected width and frequency, the high frequency and coming from the switch (6) the power selection. The emission takes place in the liquid volume (7) via the antenna (8).
L 'alimentation de ce circuit peut être réalisée à partir du secteur 220 v. suivi d' un bloc régulateur de tension donnant +5 et +15 v. continu ou par une ou plusieurs batteries précédant les régulateurs +5 et +15 v. This circuit can be powered from the 220 v mains. followed by a voltage regulator block giving +5 and +15 v. continuous or by one or more batteries preceding the +5 and +15 v regulators.
