Definitions
- Diathermy is a treatment that uses electric currents to produce tissue heating. Sometimes, diathermy is called hyperthermia, although the term diathermy is preferred to distinguish the thermal increase as a result of the passage of an electric current.
- a class of known diathermy device comprises a generator, a neutral or return electrode and an application active, both metallic, rigid, the active being able to be coated or not.
- the active electrode is smaller than the return one.
- the generator is configured to produce alternating electricity at a frequency between 0.5 and 27 MHz, fixed or selected.
- a limitation of diathermy treatments is the difficulty of its application in irregular anatomical areas (joints, bone surfaces) small (lips, periorbicular areas) or difficult to access (facial areas such as jaw, chin, ears, nose), due to the physical inability of the electrode to adapt to the body surfaces to be treated and to guarantee good contact.
- PCT Patent Document WO2008 / 049947 discloses an electrotherapy hyperthermia device comprising a generator to which a neutral electrode for application on the patient's back and a flexible and conductive active electrode, generally quadrangular, is connected.
- the active electrode has belts with sailboat that allow its placement on the back of the hand or on the forearm, depending on the size and shape of the electrode.
- the currents pass through the therapist's tissues, using the conductive properties of the human body, to the palm of his hand and from there to the patient's body.
- a conductive gel is applied between the electrode and the therapist.
- the upper face of the electrode which is not in contact with the therapist, has an insulating layer.
- the electrode is not adaptable to the zones, but the therapist's hand is interposed between the electrode and the patient.
- the therapist's hand is interposed between the electrode and the patient.
- it has the advantage that it prevents burns superficial in the patient, since the hand of the therapist also notices the heat.
- the currents pass through the body of the therapist, so it is not suitable for continued use by a certain therapist.
- US Patent US5067478 discloses a glove for combined application of analgesic or acupressure therapeutic massage and TENS therapy.
- TENS therapy uses the application of electrical currents to electrically stimulate the muscles, activating them with analgesic effects.
- the device has an electric current generator connected to a single electrode consisting of a single piece of rubber glove, in which the inner layer is insulating and the outer layer (which will remain in contact with the patient) is conductive.
- the impulses must be arranged in the frequency of up to 200 Hz, similar to the electrical impulses produced by the human nervous system.
- the inner layer is 0.762 mm, while the outer conductive layer is 0.127 mm.
- the device is applied to the muscles, combining with a massage. Another problem presented by this device is that, to maintain the hygiene measures required in medical applications, a different glove must be used for each patient, the glove being expensive to manufacture. Another problem with this glove is that contact with the skin is unpleasant.
- the present invention consists of a diathermy device comprising an alternating current generator and an electrode, the electrode and the generator being electrically connected, and characterized in that the electrode consists of a flexible glove comprising an inner layer of insulating material, a conductive intermediate layer connected to the generator and an outer layer made of an insulating material with a thickness of between 0.05 and 0.15 mm, preferably between 0.05 and 0.1 mm, such that the outer layer has an impedance of less than 50 ohms for alternating electrical currents with a frequency of between 100 kHz and 10 MHz, and because the generator is configured to generate alternating electrical currents at least in a frequency within said range of 100 kHz and 10 MHz .
- the term "glove” should be understood in a broad sense, that is, as a cover covering the hand has separate covers for each of the fingers, or several fingers share a common sheath (as in a mitten) .
- the invention is based on the fact that, because the outer layer is of a very small thickness, an electrical capacity is established between the patient's skin and the conductive layer of the glove (between 1 nF and 10nF). This causes that in the indicated frequency range there is between the skin and the layer conductive a sufficiently low impedance that allows the passage of alternating current between the conductive layer and the skin.
- the alternating current intensity depends on the frequency applied (in our case from 400 Kc / s to 1 MHz) also on voltage, on the thickness and surface of the insulating layer.
- the formula that determines the circulating intensity is proportional to 2., i.f.C.V, where "f” is the frequency, “C” is the capacity and “V” is the electrical voltage or voltage.
- the glove being flexible allows adapting to small, irregular and / or small and / or poorly accessible areas indicated.
- the present invention is not limited to obtaining the effects of a capacitive electrode, but also obtains resistive electrode effects.
- the high capacity that represents the union of the conductive part of the glove with the insulating part of the same glove in combination with the high contact surface that the glove has as an electrode makes the circulating current high enough to heat an area of the body, the foot or wrist joint and by extension any other body joint without the need to directly apply the glove in such areas, as with non-insulated stainless steel electrodes.
- the present invention provides that the glove is single piece, or is formed by layers independent of each other.
- the glove could have the inner and the intermediate layer joined together, forming a single piece, while the outer one could be an independent removable layer. This allows it to be disposable.
- the outer layer could in this case take the form of a glove. In this way, the outer layer would be discarded after each application, using different outer layers for different patients, but a single set of inner layer and intermediate layer for each therapist.
- the device object of the present invention in any of its forms, as well as the glove-shaped electrode that forms part thereof, can be used for electrotherapy applications, in particular for diathermy applications and more in Particularly in the treatment of small, irregular and / or poorly accessible areas of the human body both for purely cosmetic treatments and therapeutic treatments.
- Figure 1 is a perspective view of an embodiment of a glove belonging to a device according to the present invention.
- Figure 2 is a longitudinal section in the area of one of the fingers, of the glove of Figure 1, applied on the skin of a patient or treatment recipient.
- FIG. 1 an embodiment of a glove -1 - belonging to the device according to the present invention applied in the hand of a therapist is observed.
- the glove is connected through a suitable electric cable -5- to a generator of diathermy currents, not shown in the figures.
- the diathermy current generator of the present invention will be configured to generate alternating electric current with a frequency between 0.1 MHz and 10 MHz.
- the generator could be of known type, and therefore has not been represented in the figures.
- Figure 2 shows a longitudinal section of the glove object of the present invention, in the area of a finger -100- of the therapist.
- the drawing is schematic in terms of the thickness of the layers and the situation of the connection with the cable -5-.
- the glove is composed of three layers, an insulating inner layer -4-, whose mission is to isolate the therapist from the currents, a conductive intermediate layer -3-, connected to the generator through the cable -5- and a outer layer -2- made of an insulating material but in a very thin thickness.
- the thickness of the outer layer -2- will be between 0.05 and 0.15 mm, preferably less than 0.10 mm, for example 0.07 mm.
- an electrical capacity is produced between the patient's skin -200- and the intermediate layer -3-.
- the inner insulating layer -4 is thicker, for example between 0.5 mm and 1 mm, or greater.
- the glove can have the three layers -2-, -3-, -4- incorporated, that is to say joined together, forming a single glove.
- the inner layer -4- and the intermediate layer -3- are joined together, forming a single glove and the outer layer -2- takes the form of an independent glove that can be discarded after treatment.
- each of the layers -2-, -3-, -4- take the form of an independent glove layer.
- the therapist should first place the glove corresponding to the inner layer -4-, then the glove corresponding to the intermediate layer -3- and finally the glove corresponding to the outer layer -2-.
- the glove of the present invention has clear and indisputable advantages with reference to direct application by hand.
- the first is that with the glove we apply both the capacitive and resistive method thanks to the thickness of the outer insulation of the glove and we obtain a greater and more outstanding benefit, also faster in time.
- Another advantage of the glove is that we do not mind the heating of the hand as it happens with the direct application, it is more, we can select the degree of heating in the hand.
