DESCRIPCIÓN DESCRIPTION
Campo de la invención Field of the Invention
La presente invención se engloba en el campo gastroenterológico de la medicina, y más concretamente en los sistemas utilizados para la pérdida de peso. The present invention is encompassed in the gastroenterological field of medicine, and more specifically in the systems used for weight loss.
Antecedentes de la invención Background of the invention
Los dispositivos invasivos utilizados actualmente en tratamientos de pérdida de peso, como el balón o la banda gástrica, reducen el volumen efectivo de la cavidad estomacal, creándole así una sensación de saciedad o de llenura a los pacientes con una cantidad menor de comida, llevando a estas personas a ingerir menos alimento y por ende se induce una pérdida de peso en estos. Invasive devices currently used in weight loss treatments, such as the balloon or gastric band, reduce the effective volume of the stomach cavity, thus creating a feeling of fullness or fullness to patients with a smaller amount of food, leading to These people eat less food and therefore a loss of weight is induced in these.
Los dispositivos utilizados actualmente son ingresados a los pacientes ya sea vía oral en el caso del balón gástrico, o por cirugía mínimamente invasiva cuando se habla de la banda gástrica. Los pacientes que se someten a este tratamiento tienen una alta probabilidad de sufrir episodios constantes de vómito, dispepsia y/o de reflujo, entre otros, cuando se ingiere comida, debido al efecto creado por los elementos mencionados anteriormente. En otras palabras, la reducción en el volumen gástrico disponible por medio de estos dispositivos hace que el llenado gástrico se dé con mayor facilidad, ocasionando los efectos adversos antes mencionados y el rechazo del alimento. The devices currently used are admitted to patients either orally in the case of the gastric balloon, or by minimally invasive surgery when talking about the gastric band. Patients who undergo this treatment have a high probability of suffering constant episodes of vomiting, dyspepsia and / or reflux, among others, when eating food, due to the effect created by the elements mentioned above. In other words, the reduction in gastric volume available through these devices makes gastric filling easier, causing the aforementioned adverse effects and food rejection.
Los balones o bandas gástricas implementados actualmente que permiten cambiar su volumen interno requieren implícitamente que este sea cambiado de manera invasiva, como por ejemplo en el divulgado en el documento de patente US20090149879-A1 . Además, el volumen y presión que estos ejercen o que se ejerce sobre ellos no es retroalimentado en ningún momento a los usuarios o al personal de atención en salud. The gastric balls or bands currently implemented that allow to change their internal volume implicitly require that this be changed in an invasive manner, as for example in the one disclosed in the patent document US20090149879-A1. In addition, the volume and pressure they exert or exert on them is not fed back at any time to users or health care staff.

Descripción detallada de la invención Detailed description of the invention
La presente invención se refiere a un dispositivo para tratamiento de la obesidad, que se implanta dentro de la cavidad estomacal. The present invention relates to a device for the treatment of obesity, which is implanted within the stomach cavity.
La Figura 1 muestra una vista de elevación frontal del dispositivo 1 para tratamiento de la obesidad, el cual comprende un elemento expandible 2, que cambia de volumen dentro del estómago por acción de un actuador 7 que comprende un elemento electromecánico que permite modificar el volumen según sea programado para realizar su acción terapéutica. Dependiendo de la cantidad de volumen que este elemento expandible 2 ocupe dentro de la cavidad estomacal, aumenta o disminuye la capacidad del estómago de alojar alimento y por ende contribuye a la pérdida de peso. Figure 1 shows a front elevation view of the device 1 for treatment of obesity, which comprises an expandable element 2, which changes volume within the stomach by the action of an actuator 7 comprising an electromechanical element that allows the volume to be modified according to be programmed to perform its therapeutic action. Depending on the amount of volume that this expandable element 2 occupies within the stomach cavity, it increases or decreases the stomach's ability to house food and therefore contributes to weight loss.
El dispositivo 1 comprende también un encapsulado 3 en donde se albergan los componentes electrónicos y electromecánicos del dispositivo. Para ello el encapsulado dispone de unas aperturas (4a, 4b, 4c) que pueden ser utilizadas para ubicar los distintos tipos de elementos electrónicos, mecánicos o electromecánicos. En una realización, el extremo del elemento expandióle 2 se fija al encapsulado 3, de forma que la base superior del encapsulado 3 y la pared periférica del elemento expandióle 2 generan un volumen 12, controlable por el propio dispositivo. El elemento expandióle 2 está fabricado en una realización preferida por un material flexible y blando, por ejemplo silicona, que permite el control de dicho volumen 12 por medio del cambio de la presión de un fluido, por ejemplo aire, en su interior. En una realización alternativa el elemento expandióle 2 puede estar fabricado en un material rígido con lo cual el cambio de volumen no depende de la presión en su interior sino del desplazamiento de sus paredes periféricas por medio de la acción del actuador 7. The device 1 also comprises an encapsulation 3 where the electronic and electromechanical components of the device are housed. For this the encapsulation It has openings (4a, 4b, 4c) that can be used to locate the different types of electronic, mechanical or electromechanical elements. In one embodiment, the end of the expanded element 2 is fixed to the encapsulation 3, so that the upper base of the encapsulation 3 and the peripheral wall of the expanded element 2 generate a volume 12, controllable by the device itself. The expanded element 2 is manufactured in a preferred embodiment by a flexible and soft material, for example silicone, which allows the control of said volume 12 by changing the pressure of a fluid, for example air, inside. In an alternative embodiment, the expanding element 2 may be made of a rigid material, whereby the change in volume does not depend on the pressure inside it, but on the displacement of its peripheral walls by means of the action of the actuator 7.
En la parte inferior del encapsulado 3 se encuentra un cargador inalámbrico o sistema de carga inalámbrica 5, un elemento que permite la carga inalámbrica de una fuente de almacenamiento de energía (e.g. una o varias baterías recargables) ubicada en el interior del dispositivo (no mostrada en la figura). En la parte superior del encapsulado 3 se encuentran uno o varios sensores 6 y el actuador 7, utilizados por una unidad de control del dispositivo (implementada por ejemplo mediante un microcontrolador) para regular el volumen efectivo del dispositivo. En una realización, el actuador 7 se implementa mediante unos medios neumáticos de control del volumen para inyectar o desalojar un fluido, por ejemplo aire, en el volumen 12, y los sensores 6 incluyen un sensor de presión para medir la presión del fluido alojado en el interior del volumen 12. In the lower part of the package 3 there is a wireless charger or wireless charging system 5, an element that allows wireless charging of an energy storage source (eg one or several rechargeable batteries) located inside the device (not shown in the figure). In the upper part of the package 3 there are one or several sensors 6 and the actuator 7, used by a device control unit (implemented for example by a microcontroller) to regulate the effective volume of the device. In one embodiment, the actuator 7 is implemented by pneumatic volume control means for injecting or dislodging a fluid, for example air, in volume 12, and the sensors 6 include a pressure sensor for measuring the pressure of the fluid housed in the inside of volume 12.
La Figura 2 representa una vista inferior del dispositivo 1 en donde se pueden ver unos puertos de acceso o aperturas adicionales (8a, 8b) y un elemento ferromagnético 9 (e.g. un imán) utilizado para el desplazamiento o reubicación del dispositivo 1 desde el exterior de manera no invasiva. Figure 2 represents a bottom view of the device 1 where you can see additional access ports or openings (8a, 8b) and a ferromagnetic element 9 (eg a magnet) used for the movement or relocation of the device 1 from the outside of non-invasive way.
Las Figuras 3 y 4 ilustran, respectivamente, una vista lateral derecha e izquierda del dispositivo 1 , en donde se aprecia un puerto o cavidad practicado a ambos lados del encapsulado 3 del dispositivo para ubicar en cada uno de ellos una cámara (10a, 10b) encargada de transmitir imágenes del interior del estómago en caso de que se necesite una revisión puntual de la cavidad estomacal. Alrededor de la cámara se ubican elementos o medios emisores de luz (1 1 a, 1 1 b) que permiten iluminar la cavidad estomacal cuando se vayan a realizar exámenes. En otra realización se utiliza una única cámara, en lugar de dos, para aumento de autonomía y reducción de tamaño, complejidad y coste. Si bien en la realización de las figuras se muestra un único elemento ferromagnético 9 ubicado en la base del dispositivo 1 , en otras posibles realizaciones se puede incorporar más elementos ferromagnéticos en el contorno del encapsulado 3, por ejemplo en sus laterales, para permitir más grados de libertad y mayor control de la rotación del dispositivo 1 , realizado externamente mediante uno o varios imanes. De esta forma, se puede tener un mayor control de la orientación del dispositivo 1 y de la rotación de las cámaras (10a, 10b). Figures 3 and 4 illustrate, respectively, a right and left side view of the device 1, where a port or cavity can be seen on both sides of the encapsulation 3 of the device for locating in each of them a camera (10a, 10b) responsible for transmitting images of the inside of the stomach in case a timely review of the stomach cavity is needed. Light emitting elements or means (1 1 a, 1 1 b) are placed around the chamber that allow the stomach cavity to be illuminated when examinations are to be performed. In another embodiment, a single camera is used, instead of two, to increase autonomy and reduce size, complexity and cost. Although in the embodiment of the figures a single ferromagnetic element 9 is shown located at the base of the device 1, in other possible embodiments more ferromagnetic elements can be incorporated in the contour of the package 3, for example on its sides, to allow more degrees of freedom and greater control of the rotation of the device 1, performed externally by means of one or more magnets. In this way, you can have greater control of the orientation of the device 1 and the rotation of the cameras (10a, 10b).
Después de su implantación en el estómago, el dispositivo 1 puede cambiar el volumen que ocupa de manera remota sin tener que intervenir al paciente. El dispositivo 1 se comunica de manera inalámbrica, utilizando un módulo de comunicaciones inalámbrico (por ejemplo, utilizando Bluetooth de baja energía), con un dispositivo externo al paciente con el cual se puede efectuar un intercambio de datos entre las dos partes. De esta forma, la unidad de control (no mostrada en las figuras) alojada o soportada en el encapsulado 3 puede recibir comandos remotos para el control del volumen del elemento expandible 2. La unidad de control procede a regular el volumen 12 del elemento expandible 2, en función de la información contenido en dicho comando y de la información procedente de los sensores 6 por medio del actuador 7. After implantation in the stomach, the device 1 can change the volume it occupies remotely without having to intervene the patient. The device 1 communicates wirelessly, using a wireless communications module (for example, using Bluetooth low energy), with a device external to the patient with which an exchange of data between the two parties can be made. In this way, the control unit (not shown in the figures) housed or supported in the package 3 can receive remote commands for the control of the volume of the expandable element 2. The control unit proceeds to regulate the volume 12 of the expandable element 2 , depending on the information contained in said command and the information coming from the sensors 6 by means of the actuator 7.
La unidad de control está constantemente leyendo variables de interés dentro del estómago capturadas por los diferentes sensores del dispositivo 1 , las cuales pueden ser almacenadas en una memoria interna de la unidad de control o enviadas a la unidad externa para un posterior análisis. La unidad de control se puede implementar por ejemplo mediante un microcontrolador. The control unit is constantly reading variables of interest within the stomach captured by the different sensors of device 1, which can be stored in an internal memory of the control unit or sent to the external unit for further analysis. The control unit can be implemented, for example, by a microcontroller.
El actuador 7 del dispositivo 1 comprende un elemento electromecánico que, mediante el control del volumen del elemento expandible 2, permite cambiar su forma para ocupar más o menos espacio dentro de la cavidad estomacal. The actuator 7 of the device 1 comprises an electromechanical element that, by controlling the volume of the expandable element 2, allows it to change its shape to occupy more or less space within the stomach cavity.
El sistema de carga inalámbrica 5 permite recibir la energía necesaria, transferida desde un sistema externo, para recargar una fuente de almacenamiento de energía (e.g. una )interna del dispositivo. El dispositivo 1 tiene en la periferia de su encapsulado 3 distintos puertos de acceso o aperturas (4a, 4b, 4c, 8a, 8b) en donde se pueden ubicar elementos electrónicos o electromecánicos adicionales, tales como actuadores o sensores, entre otros. The wireless charging system 5 allows to receive the necessary energy, transferred from an external system, to recharge an internal energy storage source (e.g. one) of the device. The device 1 has on the periphery of its package 3 different access ports or openings (4a, 4b, 4c, 8a, 8b) where additional electronic or electromechanical elements, such as actuators or sensors, among others, can be located.
El elemento ferromagnético 9, implementado por ejemplo mediante un imán, permite la reubicación o el desplazamiento del dispositivo 1 dentro de la cavidad estomacal. Dicha reubicación se logra haciendo uso de un campo electromagnético externo, el cual desplaza el dispositivo 1 en la dirección deseada. El actuador 7 es un elemento electromecánico encargado de realizar el cambio en el volumen ocupado por el elemento expandible 2, modificando con ello el volumen disponible en la cavidad estomacal. El cambio de volumen se puede realizar de diferentes maneras, como por ejemplo de manera neumática o hidráulica. Debido a la ubicación del dispositivo 1 dentro del organismo, todos los materiales utilizados que puedan entrar en contacto con el paciente son biocompatibles y de grado implantable. The ferromagnetic element 9, implemented for example by means of a magnet, allows the relocation or movement of device 1 into the stomach cavity. Said relocation is achieved by using an external electromagnetic field, which moves the device 1 in the desired direction. The actuator 7 is an electromechanical element responsible for making the change in the volume occupied by the expandable element 2, thereby modifying the volume available in the stomach cavity. The volume change can be done in different ways, such as pneumatically or hydraulically. Due to the location of the device 1 within the organism, all the materials used that may come into contact with the patient are biocompatible and implantable grade.
