SISTEMA DE INMOVILIZACIÓN PERSONALIZADLEPERSONALIZED IMMOBILIZATION SYSTEM

SECTOR DE LA TÉCNICASECTOR OF THE TECHNIQUE

La presente invención se refiere a un sistema de inmovilización personalizadle para inmovilización de personas y extremidades. El sistema ha sido concebido y realizado para obtener numerosas y notables ventajas respecto a otros medios existentes de análogas finalidades.The present invention relates to a custom immobilization system for immobilization of people and limbs. The system has been conceived and realized to obtain numerous and notable advantages over other existing means of analogous purposes.

El sistema está previsto para lograr inmovilizar una persona o extremidad reduciendo las posibilidades de movimientos voluntarios o involuntarios. Para ello, el sistema cuenta con 4 partes bien diferenciadas que encajan entre sí formando un único objeto que es capaz de adaptarse a la anatomía de cada persona e inmovilizar dicha región anatómica.The system is intended to immobilize a person or limb reducing the chances of voluntary or involuntary movements. For this, the system has 4 distinct parts that fit together forming a single object that is capable of adapting to each person's anatomy and immobilizing said anatomical region.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Se conocen varios sistemas y dispositivos para la inmovilización de personas o extremidades.Several systems and devices for the immobilization of people or limbs are known.

En tal sentido pueden citarse sistemas basados en vendas impregnadas en yeso que tras mojarse se colocan en la extremidad a inmovilizar hasta que se sequen creando un armazón de yeso reforzado por la maya de tela.In this sense, systems based on bandages impregnated in plaster can be cited which, after being wetted, are placed on the limb to be immobilized until they dry creating a plaster frame reinforced by the fabric maya.

Este sistema presenta diversos inconvenientes, tales como son la reutilización de los materiales, la cual conlleva gran dificultad dada la contaminación del sistema, como las altas temperaturas necesarias para reactivar el yeso, o que normalmente para extraer la extremidad se cortan las ventas por lo que estas son de un solo uso. Además la colocación de guías metálicas que permitan el cortado de yeso a veces produce reacciones alérgicas que sólo son detectadles tras la extracción del yeso cuando éstas ya son de gran importancia.This system has several disadvantages, such as the reuse of materials, which entails great difficulty given the contamination of the system, such as the high temperatures necessary to reactivate the plaster, or that normally to cut the limb the sales are cut so that These are single use. In addition, the placement of metal guides that allow plaster cutting sometimes produces allergic reactions that are only detectable after the removal of the plaster when they are already of great importance.

Igualmente, se conocen otros sistemas basados en plásticos espumosos de alta densidad que presentan una distribución anatómicamente compatible con la mayoría de las personas y que se ajustan a las mismas mediante cintas correderas que se ajustan alrededor. Este sistema presenta grandes limitaciones de aplicabilidad puesto que se trata de un sistema basado en presión que no supone una auténtica inmovilización si no que limita los movimientos suaves además de ser incomodó a largo plazo y no permitir el control ante cualquier variación, como pueda ser la presencia de una herida abierta con gasas, o la presencia de objetos entre el plástico inmovilizado y la persona.Likewise, other systems based on high density foamy plastics are known that have an anatomically compatible distribution with most people and that adjust to them by sliding belts that fit around. This system has great limitations of applicability since it is a pressure-based system that does not suppose a true immobilization but rather limits the smooth movements in addition to being uncomfortable in the long term and does not allow control before any variation, such as presence of an open wound with gauze, or the presence of objects between the immobilized plastic and the person.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El sistema de inmovilización personalizadle de la invención presenta una nueva estrategia a la hora de personalizar la superficie del inmovilizador: en vez de deformar un elástico se rellena mediante un fluido cristalizabie y una vez adopta la forma deseada se cristaliza. Basándose en las propiedades de superenfriamiento del acetato sódico trihidratado se dispone un sistema de inyección comunicado con una bolsa adaptable ambos rellenos de una disolución saturada de acetato sódico la cual se dispone alrededor de la extremidad a inmovilizar, soportada por la carcasa externa de forma que al inyectar más disolución la bolsa adopte la forma de la extremidad.The personalized immobilization system of the invention presents a new strategy when it comes to personalizing the surface of the immobilizer: instead of deforming an elastic, it is filled with a crystallizable fluid and once it adopts the desired form it crystallizes. Based on the supercooling properties of the trihydrated sodium acetate, an injection system is provided communicated with an adaptable bag, both filled with a saturated sodium acetate solution which is arranged around the limb to be immobilized, supported by the outer shell so that at inject more solution the bag adopt the shape of the limb.

Además, se ha previsto que el sistema cuente con su propio nucleador comunicado con la bolsa adaptable y también relleno de disolución la cual al nuclear provoque la cristalización del acetato sódico trihidratado.In addition, the system is expected to have its own nucleator communicated with the adaptable bag and also filled with solution which causes the nuclear to crystallize the sodium acetate trihydrate.

También existe la posibilidad de introducir puntos débiles en la bolsa adaptable de forma que la cantidad de disolución y en consecuencia el grosor del cristal en ese punto sea mínimo permitiendo de esta forma mayor flexibilidad en estos puntos.There is also the possibility of introducing weak points in the adaptable bag so that the amount of dissolution and consequently the thickness of the glass at that point is minimal, thus allowing greater flexibility in these points.

partes del sistema, y múltiples técnicas que podríamos utilizar en la confección de la bolsa adaptable. No obstante, por simple economía se eligen materiales y técnicas generalizadas. Así pues, para la bolsa adaptable, se ha elegido nitrilo inyectado en molde y para el sistema de inyección se usa una jeringuilla de las dadas habitualmente para fines sanitarios unidad a la bolsa adaptable mediante silicona. El nucleador usará una la lámina elástica de nitrilo más gruesa que el resto de la bolsa adaptable mientras que la lámina metálica y la punta metálica serán de aluminio. La carcasa externa será de espuma de polietileno de alta densidad.parts of the system, and multiple techniques that we could use in making the adaptable bag. However, for simple economy, generalized materials and techniques are chosen. Thus, for the adaptable bag, nitrile injected in mold has been chosen and for the injection system a syringe of those given usually for sanitary purposes is used unit to the adaptable bag by silicone. The nucleator will use a thicker nitrile elastic sheet than the rest of the adaptable bag while the metal sheet and the metal tip will be aluminum. The outer shell will be made of high density polyethylene foam.

En consecuencia, para poder inmovilizar la muñeca de una persona se coloca el sistema de inmovilización personalizadle en la muñeca, se prepara el sistema de inyección hasta que la bolsa se ajusta a la forma de la muñeca, tras lo cual se presiona el nucleador y a los pocos segundos se producirá una reacción que producirá calor y se formará un cristal con la forma de la muñeca inmovilizando ésta. Cuando se desee retirar el sistema se retira primero la carcasa y a continuación se abre la bolsa valiéndose de los puntos débiles como bisagras. Se introduce la bolsa en un baño térmico a 80 grados hasta que todo el acetato haya pasado a estado líquido, momento en que se recarga el sistema de inyección, se autoclavan todas las partes y se vuelven a montar.Consequently, in order to immobilize a person's wrist, the personalized immobilization system is placed on the wrist, the injection system is prepared until the bag adjusts to the shape of the wrist, after which the nucleator is pressed and A few seconds will produce a reaction that will produce heat and a crystal will form with the shape of the wrist immobilizing it. When it is desired to remove the system, the case is first removed and then the bag is opened using the weak points as hinges. The bag is introduced in a thermal bath at 80 degrees until all the acetate has gone into a liquid state, at which time the injection system is recharged, all parts are autoclaved and reassembled.

En caso de urgencia puede retirarse un área concreta de la bolsa y disolver con agua el acetato de ese punto para tener acceso directo de ese punto de la zona inmovilizada, manteniendo el resto inmovilizado.In case of emergency, a specific area of the bag can be removed and the acetate of that point dissolved with water to have direct access to that point in the immobilized area, keeping the rest immobilized.

Serán independientes del objeto de la invención los materiales empleados en la fabricación de los componentes del sistema de inmovilización personalizare, formas y dimensiones de los mismos, y todos los detalles accesorios, que puedan presentarse, siempre y cuando no afecten a su esencialidad.The materials used in the manufacture of the components of the personal immobilization system, their shapes and dimensions, and all the accessory details, which may be presented, will be independent of the object of the invention, provided they do not affect their essentiality.
