APPLICATORE PER DIATERMIA CON SENSORE DI TEMPERATURA INTEGRATO DIATHERMY APPLICATOR WITH INTEGRATED TEMPERATURE SENSOR
La presente invenzione industriale riguarda un applicatore per diatermia con sensore di temperatura integrato. The present industrial invention relates to a diathermy applicator with integrated temperature sensor.
Campo della tecnica field of technique
Come ? noto la diatermia ? un metodo terapeutico che consiste nell'innalzare la temperatura di una parte interna del corpo facendola attraversare da corrente elettrica a bassa tensione e ad alta frequenza, da onde magnetiche o da ultrasuoni; viene usata ? tra le altre applicazioni - nella cura di alcune forme reumatiche di natura muscolare. Nel caso specifico dell?utilizzo di corrente elettrica, il riscaldamento avviene per mezzo del fenomeno fisico noto come Effetto Joule. As ? Do I notice the diathermy? a therapeutic method which consists in raising the temperature of an internal part of the body by passing it through a low-voltage and high-frequency electric current, magnetic waves or ultrasounds; it is used ? among other applications - in the treatment of some rheumatic forms of a muscular nature. In the specific case of the use of electric current, heating takes place by means of the physical phenomenon known as the Joule Effect.
Evidentemente la temperatura che pu? essere raggiunta all?interno dei tessuti interessati dalla diatermia deve essere attentamente monitorata, al fine di effettuare un trattamento efficace e sicuro: il raggiungimento di temperature troppo basse vanificherebbe infatti l?efficacia del trattamento, mentre il raggiungimento di temperature troppo alte potrebbe causare danni ai tessuti invece che benefici. Evidently the temperature that can? be reached within the tissues affected by diathermy must be carefully monitored, in order to carry out an effective and safe treatment: reaching temperatures that are too low would in fact nullify the effectiveness of the treatment, while reaching temperatures that are too high could cause damage to the fabrics instead of benefits.
Evidentemente la misura che pu? essere eseguita ? quella della temperatura cutanea in corrispondenza della zona di applicazione, non potendo essere direttamente eseguita una misura di temperatura all?interno dei tessuti. Evidently the measure that pu? be performed ? that of the skin temperature in correspondence with the area of application, since it is not possible to directly measure the temperature inside the tissues.
Sono note a tale scopo alcune soluzioni per integrare la misura della temperatura con l?applicazione di potenziale elettrico a radiofrequenza. For this purpose, some solutions are known for integrating the temperature measurement with the application of electric potential at radio frequency.
CN107582235 descrive un apparato per diatermia comprendente una pluralit? di elettrodi ed un sistema di controllo per applicare un potenziale elettrico a radiofrequenza tra gli stessi, in modo da riscaldare mediante diatermia il corpo ad una temperatura tra 30 ed 80?C. CN107582235 discloses a diathermy apparatus comprising a plurality of electrodes and a control system for applying a radiofrequency electric potential between them, so as to heat the body by diathermy to a temperature between 30 and 80°C.
GB460745 descrive un apparato per diatermia comprendente un circuito di misura dotato di una termocoppia, collegata tramite un filtro in frequenza all?avvolgimento cui sono collegati gli elettrodi. GB460745 describes a diathermy apparatus comprising a measuring circuit equipped with a thermocouple, connected via a frequency filter to the winding to which the electrodes are connected.

Scopo dell?invenzione Purpose of the invention
La presente invenzione intende fornire un applicatore per diatermia in grado di fornire una misura di temperatura della cute nella zona oggetto di applicazione che sia pi? affidabile rispetto alle misure eseguite con i dispositivi noti allo stato dell?arte, e che non richieda l?installazione sull?applicatore di altri componenti che non siano gli elettrodi utilizzati per la stimolazione elettrica dei tessuti. The present invention intends to provide a diathermy applicator capable of providing a measurement of the temperature of the skin in the area to be applied which is more? reliable compared to the measurements performed with devices known in the state of the art, and which does not require the installation on the applicator of other components other than the electrodes used for the electrical stimulation of the tissues.

The invention achieves the intended aims as it is a diathermy device comprising an applicator (1) equipped with at least one pair of electrodes (3, 4) and a unit control (7), configured to apply a radiofrequency electric potential between them characterized in that each electrode (3, 4) of said at least one pair of electrodes comprises at least two parts (31, 32, 41, 42) made of metals and/or metal alloys that are different from each other and electrically connected to each other.
Descrizione dettagliata dell?invenzione Detailed description of the invention
Il trovato sar? ora descritto con riferimento alle allegate figure da 1 a 3. The found sar? now described with reference to the attached figures 1 to 3.
In figura 1 e 2 sono mostrate due viste schematiche di un applicatore (1) per diatermia e della relativa unit? di controllo (2). Figures 1 and 2 show two schematic views of an applicator (1) for diathermy and of the relative unit? control (2).
In figura 3 ? mostrata una vista di una applicazione di diatermia da parte di un operatore su di una paziente. In figure 3 ? shown is a view of an operator applying diathermy to a patient.
Come evidente dalle figure allegate, il dispositivo secondo la presente invenzione ? un dispositivo per diatermia comprendente un applicatore (1) dotato di almeno una coppia di elettrodi (3, 4) ed una unit? di controllo (7), configurata per applicare un potenziale elettrico a radiofrequenza tra gli stessi. Evidentemente l?unit? di controllo (2) comprende anche mezzi di comando, di per s? noti allo stato dell?arte, per consentire l?attivazione e lo spegnimento del macchinario, e per regolare l?intensit? del trattamento (potenziale applicato e frequenza). As evident from the attached figures, the device according to the present invention ? a diathermy device comprising an applicator (1) equipped with at least one pair of electrodes (3, 4) and a unit? controller (7), configured to apply a radiofrequency electric potential between them. Evidently the unit? of control (2) also includes command means, per se? known to the state of the art, to allow the activation and shutdown of the machinery, and to adjust the intensity? of the treatment (potential applied and frequency).
Con riferimento all?applicatore (1), lo stesso ? caratterizzato dal fatto che ciascun elettrodo di detta almeno una coppia di elettrodi comprende almeno due parti (31, 32, 41, 42) realizzate in metalli e/o leghe metalliche tra loro differenti ed elettricamente collegate le une alle altre. With reference to the applicator (1), the same ? characterized in that each electrode of said at least one pair of electrodes comprises at least two parts (31, 32, 41, 42) made of different metals and/or metal alloys and electrically connected to each other.
Si specifica che i due elettrodi (3, 4) non sono tra loro elettricamente collegati, essendo utilizzati per l?applicazione di un potenziale elettrico, e sono invece collegate tra loro esclusivamente: la prima parte (31) del primo elettrodo (3) con la seconda parte (32) del primo elettrodo (3), e la prima parte (41) del secondo elettrodo (4) con la seconda parte (42) del secondo elettrodo (4). It is specified that the two electrodes (3, 4) are not electrically connected to each other, being used for the application of an electric potential, and are instead connected to each other exclusively: the first part (31) of the first electrode (3) with the second part (32) of the first electrode (3), and the first part (41) of the second electrode (4) with the second part (42) of the second electrode (4).
Esempi di copie di metalli utilizzabili sono: Nichel Cromo e Nichel-Alluminio; ferro e Rame-Nichel; rame e rame-Nichel; Nichel-cromo e rame-Nichel; Nichel Cromo e nichel-alluminio, acciaio-titanio. Examples of copies of usable metals are: Nickel-Chromium and Nickel-Aluminium; iron and Copper-Nickel; copper and copper-Nickel; Nickel-chromium and copper-Nickel; Nickel Chromium and nickel-aluminium, steel-titanium.
Eventualmente ciascun elettrodo pu? essere rivestito con un rivestimento elettricamente e termicamente conduttivo, in materiale biocompatibile. Possibly each electrode pu? be coated with an electrically and thermally conductive coating, made of biocompatible material.
Ciascuno dei due elettrodi pu? fungere in questa maniera: Each of the two electrodes pu? work like this:
- da elettrodo di applicazione del potenziale RF per l?esecuzione della terapia; - da termocoppia di misura della temperatura cutanea - from an electrode for applying the RF potential for carrying out the therapy; - by thermocouple for skin temperature measurement
L?unit? di controllo (2) oppure l?applicatore (1) comprendono inoltre almeno un circuito di lettura della temperatura rilevata dagli elettrodi, dotato di circuito di compensazione (giunzione fredda) e di circuito di amplificazione del potenziale. Convenientemente inoltre tra ciascun elettrodo ed il relativo circuito di lettura della termocoppia ? presente un filtro in frequenza di tipo passa basso, che eviti la possibilit? di passaggio del potenziale a radiofrequenza verso il circuito di lettura della termocoppia. The unit controller (2) or the applicator (1) also comprise at least one reading circuit of the temperature detected by the electrodes, equipped with a compensation circuit (cold junction) and a potential amplification circuit. Conveniently also between each electrode and the relative reading circuit of the thermocouple ? present a frequency filter of the low-pass type, which avoids the possibility? passage of the radiofrequency potential towards the reading circuit of the thermocouple.
? evidente che questa configurazione consente, senza aggiungere alcun sensore all?applicatore (1), di misurare la temperatura il pi? vicino possibile alla cute. Preferibilmente ciascuna parte (31, 32, 41, 42) di ciascuno di detti elettrodi (3, 4) ? realizzata in forma di superficie curva convessa, e preferibilmente in forma di calotta sferica. ? it is evident that this configuration allows, without adding any sensor to the applicator (1), to measure the temperature as quickly as possible. close to the skin as possible. Preferably each part (31, 32, 41, 42) of each of said electrodes (3, 4) ? made in the form of a convex curved surface, and preferably in the form of a spherical cap.
In questa maniera ? reso pi? agevole il movimento dell?applicatore sulla cute. Ancor pi? preferibilmente ciascuna parte (31, 32, 41, 42) di ciascuno di detti elettrodi (3, 4) ? internamente cava, al fine di diminuire la propria inerzia termica. Preferibilmente inoltre l?unit? di controllo ? configurata per eseguire cicli che prevedono le fasi di: In this way ? made more facilitates the movement of the applicator on the skin. even more preferably each part (31, 32, 41, 42) of each of said electrodes (3, 4) ? internally hollow, in order to decrease its thermal inertia. Preferably also the? unit? control ? configured to run cycles that include the phases of:
