Description

DESCRIPCIÓN  DESCRIPTION
Dispositivo de intubación endotraqueal por imantación Objeto de la invención Magnetic endotracheal intubation device Object of the invention
Es objeto de la presente invención un novedoso sistema de intubación endotraqueal que permite la manipulación remota del extremo distal mediante un elemento que es manejado por el anestesista en el exterior de la zona faríngea del paciente a intubar. The object of the present invention is a novel endotracheal intubation system that allows remote manipulation of the distal end by means of an element that is managed by the anesthetist outside the pharyngeal area of the patient to be intubated.
Antecedentes de la invención Background of the invention
En la actualidad casi todas las intervenciones quirúrgicas realizadas en un hospital se hacen con anestesia general, regional o local, si bien es cierto que la mayoría de ellas se realizan con anestesia general. Para anestesiar de manera general a un paciente, es necesario inducirle un estado de inconsciencia controlada que necesita ventilación artificial con ayuda de un respirador externo. Para que esta respiración artificial sea efectiva es fundamental que exista un circuito y una conexión entre respirador y el paciente. El referido circuito requiere que la conexión con el paciente se haga a través de un tubo, llamado tubo endotraqueal, que es alojado en el interior de las vías respiratorias del paciente. Currently, almost all surgical interventions performed in a hospital are performed under general, regional or local anesthesia, although it is true that most of them are performed under general anesthesia. To general anesthetize a patient, it is necessary to induce a state of controlled unconsciousness that needs artificial ventilation with the help of an external respirator. For this artificial respiration to be effective it is essential that there is a circuit and a connection between respirator and the patient. The aforementioned circuit requires that the connection with the patient be made through a tube, called the endotracheal tube, which is housed inside the patient's airways.
La introducción del tubo endotraqueal, que se realiza con la ayuda de un instrumento que permite la visualización de las estructuras orales y faríngeas llamado laringoscopio, se denomina intubación. The introduction of the endotracheal tube, which is done with the help of an instrument that allows the visualization of the oral and pharyngeal structures called the laryngoscope, is called intubation.
En escasas ocasiones, entre el 1 % y el 4% de los casos, la visualización de la glotis y la laringe es dificultosa por las distintas características anatómicas y físicas del paciente, con lo que la introducción del tubo endotraqueal se realiza "a ciegas" y con frecuencia se hace imposible. Esta circunstancia implica, en la práctica diaria del ejercicio de la anestesia quirúrgica, un riesgo absoluto para la vida del paciente, y la gran mayoría de las complicaciones consideradas graves o con resultado de muerte durante la realización de una anestesia, van asociadas a un problema relacionado con las vías aéreas y la imposibilidad de suministrar oxígeno al paciente. Las mayoría de las soluciones existentes para mejorar la técnica de la intubación, han ido por la mejora en la visualización de esas estructuras anatómicas, ya sea bien por observación directa con una pequeña cámara, como el fibrobroncoscopio o el fibrolaringoscopio, o bien por la creación de diferentes dispositivos, llamados supraglóticos por quedar colocados por encima de la de la glotis que es la puerta de entrada a la tráquea, que facilitan la colocación "a ciegas" del mismo y que aseguran una eficaz administración de oxígeno. Pero ninguna de estas soluciones entraría más allá de las cuerdas vocales, sino antes de las mismas, con lo que el circuito entre el respirador y el árbol respiratorio del paciente no quedaría estanco y en caso de vómito no se podría prevenir la broncoaspiración, tan temida en anestesia. Estos dispositivos suponen por tanto un problema para la seguridad del paciente puesto que no mantienen asegurada ni estanca las vías aéreas. On rare occasions, between 1% and 4% of cases, the visualization of the glottis and the larynx is difficult due to the different anatomical and physical characteristics of the patient, so that the introduction of the endotracheal tube is performed "blindly" and often it becomes impossible. This circumstance implies, in the daily practice of surgical anesthesia, an absolute risk to the patient's life, and the vast majority of complications considered serious or resulting in death during the performance of an anesthesia, are associated with a problem. related to the airways and the impossibility of supplying oxygen to the patient. Most of the existing solutions to improve the technique of intubation, have gone for the improvement in the visualization of these anatomical structures, either by direct observation with a small camera, such as the fibrobronchoscope or the fibrolaringoscope, or by the creation of different devices, called supraglotics because they are placed above that of the glottis that is the gateway to the trachea, which facilitate placement " blindly "of the same and that ensure an effective administration of oxygen. But none of these solutions would enter beyond the vocal cords, but before them, so that the circuit between the respirator and the patient's respiratory tree would not be tight and in case of vomiting the bronchoaspiration could not be prevented, so feared in anesthesia These devices therefore pose a problem for patient safety since they do not keep the airways secured or stagnant.
Descripción de la invención Description of the invention
El dispositivo de intubación endotraqueal por imantación, objeto de la presente invención, es de aquellos que comprenden un tubo endotraqueal que se introduce en las vías respiratorias del paciente, consiste en un imán, que está destinado a ser manipulado por el anestesista en el exterior del cuello del paciente a la altura de la faringe y de la laringe, y en un elemento metálico dispuesto en el extremo distal del tubo endotraqueal. Breve descripción de la figura The magnetization endotracheal intubation device, object of the present invention, is one of those comprising an endotracheal tube that is inserted into the patient's airways, consists of a magnet, which is intended to be manipulated by the anesthetist outside the neck of the patient at the level of the pharynx and larynx, and in a metallic element arranged at the distal end of the endotracheal tube. Brief description of the figure
Figura 1 : muestra una vista en alzado de la invención. Realización preferente Figure 1: shows an elevation view of the invention. Preferred embodiment
La figura 1 muestra una realización preferente del dispositivo de intubación endotraqueal por imantación, que es de aquellos que comprenden un tubo endotraqueal (1 ) que se introduce en las vías respiratorias del paciente, y que consiste en un imán (2), el cual está destinado a ser manipulado por el anestesista en el exterior del cuello a la altura de la faringe y de la laringe, y en un elemento metálico (3) dispuesto en el extremo distal del tubo endotraqueal (1 ). Con el objetivo principal de evitar lesionar al paciente con un elemento excesivamente duro, evitar su deterioro y de que la unión del elemento metálico al tubo sea muy sencilla, el elemento metálico puede estar dispuesto en el interior del extremo distal del tubo endotraqueal y que puede estar recubierto por el mismo material del que está hecho el referido tubo endotraqueal. Como es previsible al acercar el imán, que puede estar incorporado en un soporte de forma ergonomica para facilitar su manipulación, el elemento metálico es atraído por dicho imán, facilitando su orientación y aproximación, lo que permite una inserción segura y un circuito estanco que evite e impida las posibles problemas para la vida del paciente. Figure 1 shows a preferred embodiment of the magnetization endotracheal intubation device, which is one of those comprising an endotracheal tube (1) that is inserted into the patient's airways, and consisting of a magnet (2), which is intended to be manipulated by the anesthesiologist on the outside of the neck at the level of the pharynx and larynx, and in a metal element (3) arranged at the distal end of the endotracheal tube (1). With the main objective of avoiding injury to the patient with an excessively hard element, preventing its deterioration and that the union of the metallic element to the tube is very simple, the metallic element can be arranged inside the distal end of the endotracheal tube and that can be covered by the same material from which the aforementioned endotracheal tube is made. As it is foreseeable when approaching the magnet, which can be incorporated in an ergonomically shaped support to facilitate its handling, the metallic element is attracted by said magnet, facilitating its orientation and approximation, which allows a safe insertion and a tight circuit that avoids and prevent possible problems for the patient's life.
