Abstract

The invention relates to a seat suitable for patients that have to maintain a face-down rest position, for example patients that have undergone vitrectomy, which seat allows the patient to maintain this face-down rest position for long periods without causing cramping, as well as allowing the patient to look at objects such as a book or objects positioned facing the seat. The invention has also been specially designed to allow patients to look at objects, such as a television, which are located and oriented so as to be seen while seated on a seat. The seat is also suitable for post-operative patients that have to maintain a position similar to the post-vitrectomy position for a long period of time, as is the case, for example, after certain back surgeries.

Description

SILLA APROPIADA PARA PACIENTES QUE REQUIEREN  PROPER CHAIR FOR PATIENTS THAT REQUIRE
UNA POSICIÓN DE DESCANSO CARA BOCA ABAJO A POSITION OF REST FACE BOCA BELOW
DESCRIPCIÓN DESCRIPTION
OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION
La presente invención está dirigida a una silla apropiada para pacientes que requieren una posición de descanso cara boca abajo, por ejemplo pacientes operados de vitrectomía, que le permite al paciente mantener largos periodos de reposo sin que se le produzcan contracturas mientras mantiene una posición de la cara boca abajo; y, a la vez permite que este paciente tenga acceso visual tanto a objetos tales como un libro como a otros situados en frente de la silla. La invención está también especialmente concebida para permitir el acceso visual de objetos, por ejemplo un televisor, que estén situados y orientados para ser observados sentado en un sillón.  The present invention is directed to a chair suitable for patients who require a face-down resting position, for example vitrectomy operated patients, which allows the patient to maintain long periods of rest without contractures while maintaining a position of the face down; and, at the same time, it allows this patient to have visual access to objects such as a book and others located in front of the chair. The invention is also specially designed to allow visual access of objects, for example a television, that are located and oriented to be observed sitting in an armchair.
Esta silla es también aplicable a pacientes con postoperatorios en los que se deba mantener, durante un periodo largo de tiempo, una posición similar a la del postoperatorio de vitrectomía. Este es el caso por ejemplo de algunas cirugías de espalda. This chair is also applicable to postoperative patients in whom a position similar to that of the postoperative vitrectomy should be maintained for a long period of time. This is the case for example of some back surgeries.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Los pacientes operados de vitrectomía porque por ejemplo han sufrido un desprendimiento o desgarro de retina habitualmente son tratados con técnicas que hacen uso de gases incorporados en el interior del ojo. El gas tiene un efecto de flotación que ejerce presión contra la retina mientras ésta se recupera y se fija. Para que este efecto de flotación pueda permitir la recuperación de la retina se exige al paciente que éste permanezca con el ojo mirando hacia abajo durante varios meses. Que el ojo esté mirando hacia abajo implica que tiene que permanecer boca abajo, al menos su cabeza.  Patients undergoing vitrectomy because, for example, they have suffered a retinal detachment or tear are usually treated with techniques that make use of gases incorporated inside the eye. The gas has a flotation effect that puts pressure on the retina while it recovers and sets. In order for this flotation effect to allow retinal recovery, the patient is required to remain with the eye facing down for several months. That the eye is looking down implies that you have to remain face down, at least your head.
Esta posición boca abajo tiene grandes inconvenientes. Un apoyo boca abajo sobre un almohadón dificulta la respiración y, si el periodo de convalecencia se prolonga durante meses, el paciente no tiene ningún modo de distracción visual. This upside down position has major drawbacks. A support upside down on a cushion makes breathing difficult and, if the period of convalescence lasts for months, the patient has no mode of visual distraction.
Otro inconveniente que tienen estos pacientes es la aparición de contracturas musculares debido a los prolongados periodos de tiempo en los que el músculo permanece inmóvil. Es necesario modificar con cierta frecuencia, aunque sea ligeramente, la posición del cuerpo y sus extremidades. Actualmente este tipo de pacientes tiende a permanecer en cama con ayuda de cojines y almohadones que le facilitan una posición tal y como se les exige, no obstante, estos pacientes siguen teniendo dificultades para respirar adecuadamente y sobre todo tienen impedidas actividades tales como leer o ver la televisión. La presente invención resuelve sim ultá neamente ambos problemas ya que la presente invención permite un soporte del paciente que le permite un reposo prolongado sin entumecimiento de los músculos y tener acceso visual tanto a un objeto tal como un libro como a la televisión. DESCRIPCIÓN DE LA INVENCIÓN Another inconvenience that these patients have is the appearance of contractures muscle due to prolonged periods of time in which the muscle remains immobile. It is necessary to modify with some frequency, even slightly, the position of the body and its limbs. Currently, this type of patient tends to stay in bed with the help of cushions and cushions that facilitate a position as required, however, these patients still have difficulty breathing properly and especially have activities such as reading or seeing television. The present invention simultaneously solves both problems since the present invention allows patient support that allows prolonged rest without numbing of the muscles and having visual access to both an object such as a book and television. DESCRIPTION OF THE INVENTION
La presente invención comprende una silla apropiada para pacientes operados de vitrectomía que comprende una estructura que a su vez al menos comprende los siguientes elementos:  The present invention comprises a chair suitable for vitrectomy operated patients comprising a structure that in turn at least comprises the following elements:
• un primer miembro en el que en un extremo dispone de pies de apoyo y en el extremo opuesto de un asiento,  • a first member in which at one end it has support feet and at the opposite end of a seat,
• un segundo miembro vinculado con el primer miembro de forma pivotante donde en un extremo dispone de pies de apoyo,  • a second member linked to the first pivotal member where at one end it has support feet,
• una columna principal vinculada inferiormente al conjunto formado por el primer y segundo miembro que a su vez comprende:  • a main column linked inferiorly to the set formed by the first and second member which in turn comprises:
- reposabrazos para el apoyo de los brazos del paciente,  - armrests to support the patient's arms,
- un apoyo para el pecho,  - a chest support,
- un reposacabezas adaptado para mantener la posición de la cabeza del paciente boca abajo. Esta estructura básica constituye el soporte del paciente. El primer miembro y el segundo miembro unidos de forma pivotante donde cada uno de ellos dispone en uno de sus extremos de pies es el modo de conseguir una estructura regulable en altura y estable en su apoyo con el suelo. El vínculo pivotante permite definir la altura del asiento que está en el extremo opuesto del primer miembro. Una vez determinada la altura, unos medios de fijación de la unión pivotante mantiene la posición elegida. Este vínculo pivotante, además de la altura, permite modificar la distancia entre el asiento y el apoyo para el pecho de tal modo que es posible el uso de la silla por personas con distintas alturas y también diferentes complexiones físicas. - a headrest adapted to keep the position of the patient's head upside down. This basic structure constitutes the patient's support. The first member and the second member pivotally joined where each of them has one of its feet ends is the way to achieve a height-adjustable structure that is stable in its support with the ground. The pivot link allows defining the height of the seat that is at the opposite end of the first member. Once the height has been determined, means for fixing the pivoting joint maintain the chosen position. This pivoting link, in addition to the height, allows you to modify the distance between the seat and Chest support in such a way that it is possible to use the chair by people with different heights and also different physical complexions.
A partir de esta estructura soporte, una columna principal es el soporte que permite definir la posición y altura del resto de elementos de apoyo del paciente, principalmente del tronco y miembros del tronco. El reposabrazos permite el apoyo de los brazos del paciente, el apoyo del pecho permite que éste se incline hasta descansar parte del peso contra este apoyo; y por último el reposacabezas está adaptado para mantener la posición de la cabeza del paciente tal y como se exige, boca abajo. From this support structure, a main column is the support that allows defining the position and height of the rest of the patient's support elements, mainly of the trunk and trunk members. The armrest allows the support of the patient's arms, the support of the chest allows it to lean until resting part of the weight against this support; and finally the headrest is adapted to maintain the position of the patient's head as required, face down.
Establecidos estos elementos de soporte el paciente es capaz de mantener su peso descansando en el conjunto de medios de apoyo: asiento, reposabrazos, apoyo para el pecho, reposacabezas; y por último, las piernas que apoyan principalmente a través de las espinillas en un reposapiernas o lo que se denominará generalmente apoyo mullido para rodillas y espinillas. Once these support elements are established, the patient is able to keep his weight resting on the set of support means: seat, armrests, chest support, headrest; and finally, the legs that support mainly through the shins on a legrest or what will generally be called fluffy support for knees and shins.
Que esta estructura permita, además de mantener una posición adecuada del paciente, un acceso visual para su entretenimiento se consigue mediante la combinación que establece la invención de los elementos anteriores con las siguientes características: That this structure allows, in addition to maintaining an adequate position of the patient, visual access for their entertainment is achieved through the combination established by the invention of the above elements with the following characteristics:
• la columna principal comprende un soporte adaptado para mantener objetos y, el reposacabezas, dispone de una abertura configurada para tener acceso visual a dicho soporte. • the main column comprises a support adapted to hold objects and, the headrest, has an opening configured to have visual access to said support.
El apoyo de la cabeza boca abajo exige que el paciente pueda respirar. Proveer por ejemplo de una abertura en el reposacabezas para la nariz no es suficiente. La invención exige que esta abertura sea lo suficientemente amplia como para que el paciente con los ojos abiertos tenga acceso visual a un soporte que está adaptado para mantener objetos. Un ejemplo de realización de este soporte es una base regulable en altura e inclinación cuyas posiciones se encuentran por debajo de la posición de la cabeza y siempre accesible visualmente. Este soporte permite colocar un libro que puede ser leído por el paciente sin que modifique su posición. En ejemplos de realización posteriores, tal y como se describirá más adelante, el uso de un conjunto de espejos permite al paciente tener acceso visual a objetos tales como un televisor. Este televisor no solo es un objeto que no requiere modificar su posición sino que tampoco requiere cambiar su orientación gracias al modo de combinar los espejos. Esta combinación de posiciones y orientaciones de los espejos permiten al paciente observar la imagen de la televisión orientada como si estuviese sentado frente al mismo. Head-down head support requires the patient to breathe. Providing for example an opening in the headrest for the nose is not enough. The invention requires that this opening be wide enough so that the patient with open eyes has visual access to a support that is adapted to hold objects. An example of this support is an adjustable base in height and inclination whose positions are below the position of the head and always visually accessible. This support allows you to place a book that can be read by the patient without changing their position. In subsequent embodiments, as will be described later, the use of a set of mirrors allows the patient to have visual access to objects such as a TV. This TV is not only an object that does not require changing its position but also does not need to change its orientation thanks to the way of combining mirrors. This combination of positions and orientations of the mirrors allows the patient to observe the image of the oriented television as if he were sitting in front of it.

En este ejemplo de realización el asiento (1.5) dispone de unos medios de fijación (1.5.1) que permiten establecer la inclinación de dicho asiento en el extremo o cerca del extremo del primer miembro (1.1). El asiento (1.5) se encuentra abisagrado donde en la figura 1 se indica la posibilidad de modificar la inclinación mediante una flecha curvada y un eje de giro.. Los medios de fijación (1.5.1), en este ejemplo de realización, comprenden un elemento de apoyo que se desplaza sobre la superficie del cuerpo tubular del primer miembro (1.1) a lo largo de una ranura dispuesta en el asiento (1.5) de tal modo que este desplazamiento incrementa o disminuye la inclinación del asiento (1.5). La figura 4 muestra en detalle esta solución particular de regulación de la inclinación del asiento (1.5). Mediante otra pareja de flechas curvadas se indica la capacidad de abisagrado del asiento (1.5) respecto del primer miembro (1.1). El asiento dispone de una ranura (1.5.2) por cada medio de fijación (1.5.1) que en este caso es un cono de elastómero. El cono está orientado con su base hacia arriba y en contacto con la superficie inferior del asiento (1.5). De su base emerge un espárrago roscado que sirve para quedar fijo al asiento mediante una tuerca (1.5.3) que rosca en dicho espárrago roscado. El cono queda fijo en un punto de la ranura (1.5.2) por el apriete de la tuerca (1.5.3). Dependiendo del punto de fijación del cono a lo largo de la ranura (1.5.2) se consigue que la inclinación que adopta el asiento sea mayor o menor. Figure 1 shows an example of embodiment of the invention, a chair suitable for vitrectomy operated patients, which has a floor-supported structure inferiorly formed by a first member (1.1) and a second member (1.2) pivotally linked through a hinged bar (1.3). In this example, the first member (1.1) has at one end of support feet (1.1.1) for contact with the ground and the other end is extended to support a seat (1.5). On the other hand, the second member (1.2) has, at its end of support feet (1.2.1) and arranged parallel, a soft support (1.2.2) for the patient's knees and shins. Both the first member (1.1) and the second member (1.2) they are formed by pairs of tubes arranged parallel and joined together. In this particular case the parallel tubes of the second member (1.2) are more separated than the parallel tubes that give rise to the first member (1.1). In this exemplary embodiment, the seat (1.5) has fixing means (1.5.1) that allow to establish the inclination of said seat at the end or near the end of the first member (1.1). The seat (1.5) is hinged where in Figure 1 the possibility of modifying the inclination by means of a curved arrow and a rotation axis is indicated. The fixing means (1.5.1), in this exemplary embodiment, comprise a support element that moves on the surface of the tubular body of the first member (1.1) along a groove arranged in the seat (1.5) such that this displacement increases or decreases the inclination of the seat (1.5). Figure 4 shows in detail this particular solution for adjusting the inclination of the seat (1.5). The hinged capacity of the seat (1.5) with respect to the first member (1.1) is indicated by another pair of curved arrows. The seat has a groove (1.5.2) for each fixing means (1.5.1) which in this case is an elastomer cone. The cone is oriented with its base facing up and in contact with the lower surface of the seat (1.5). From its base emerges a threaded stud that serves to be fixed to the seat by means of a nut (1.5.3) that threads into said threaded stud. The cone is fixed at a point in the groove (1.5.2) by the tightening of the nut (1.5.3). Depending on the point of fixation of the cone along the groove (1.5.2) it is achieved that the inclination adopted by the seat is greater or lesser.
Según otro ejemplo de realización, no mostrado en la figura, los medios de fijación (1.5.1) permiten tanto la modificación de la inclinación como de la posición del asiento (1.5) a lo largo del primer miembro (1.1). La modificación tanto de la posición como de la inclinación permite modificar el modo de apoyo del paciente y sobre todo el grado de curvatura que exige el paciente a su columna vertebral. Esta es una de las posiciones que el paciente requiere que sean modificables cuando se encuentra sentado durante periodos de tiempo tan prolongados como exige la convalecencia. According to another embodiment, not shown in the figure, the fixing means (1.5.1) allow both the inclination and the position of the seat (1.5) to be modified along the first member (1.1). The modification of both the position and the inclination allows modifying the mode of support of the patient and especially the degree of curvature that the patient demands to his spine. This is one of the positions that the patient requires to be modifiable when sitting for periods of time as long as convalescence demands.
En el ejemplo de realización mostrado en la figura 1, sobre el primer miembro (1.1) y en una posición intermedia situada entre la unión pivotante entre el primer y segundo miembro (1.1, 1.2) y el asiento (1.5) se encuentra una unión pivotante entre una columna principal (1.8) y el primer miembro (1.1). En esta unión pivotante se encuentra un elemento de bloqueo (1.4), responsable de la unión entre la columna principal (1.8) y el primer miembro (1.1) en puntos preestablecidos. Adicionalmente, cuenta con una pieza en forma esencialmente de cuña (1.4.1) responsable de fijar una inclinación determinada de la columna principal (1.8). En este caso particular la pieza en forma de cuña (1.4.1) es tal que dispone de al menos dos superficies convergentes que apoyan, una contra la columna principal (1.8) y otra contra los tubos del primer miembro (1.1). Al acercarse la cuña (1.4.1) hacia el eje respecto del cual la columna principal (1.8) pivota, hace que las superficies de apoyo de esta cuña abran el ángulo incrementando la inclinación de dicha columna principal (1.8). In the exemplary embodiment shown in Figure 1, a pivotal joint is located on the first member (1.1) and in an intermediate position located between the pivoting joint between the first and second members (1.1, 1.2) and the seat (1.5) between a main column (1.8) and the first member (1.1). In this pivotal joint there is a blocking element (1.4), responsible for the union between the main column (1.8) and the first member (1.1) at pre-established points. Additionally, it has an essentially wedge-shaped piece (1.4.1) responsible for fixing a certain inclination of the main column (1.8). In this particular case, the wedge-shaped part (1.4.1) is such that it has at least two converging surfaces that support, one against the main column (1.8) and the other against the tubes of the first member (1.1). As the wedge (1.4.1) approaches the axis with respect to which the main column (1.8) pivots, it makes the support surfaces of this wedge open the angle increasing the inclination of said main column (1.8).
La columna principal (1.8), en este ejemplo de realización, es a su vez el soporte de los siguientes elementos: The main column (1.8), in this exemplary embodiment, is in turn the support of the following elements:
• unos reposabrazos (1.6),  • armrests (1.6),
· un apoyo para el pecho (1.10), · A chest support (1.10),
• un reposacabezas (1.7); y,  • a headrest (1.7); Y,
• un soporte (1.8.1) para mantener objetos.  • a support (1.8.1) to hold objects.
Los reposabrazos (1.6) se encuentran dispuestos a uno y otro lado de la columna principal (1.8). En este ejemplo de realización los reposabrazos (1.6) disponen de unos medios de fijación (1.6.1) para unos medios de unión (1.6.2), en este ejemplo de realización en forma de "L", entre el reposabrazos (1.6) y la columna principal (1.8) donde estos últimos medios de unión (1.6.2) permiten modificar la posición de los brazos del paciente con movimientos en un plano horizontal. Los medios de unión (1.6.2) en forma de "L", disponen de un giro según un eje vertical que es el que dota de un grado de libertad al reposabrazos (1.6) con movimientos en un plano horizontal. The armrests (1.6) are arranged on either side of the main column (1.8). In this exemplary embodiment, the armrests (1.6) have fixing means (1.6.1) for joining means (1.6.2), in this example of an "L" shape, between the armrest (1.6) and the main column (1.8) where these last joining means (1.6.2) allow to modify the position of the patient's arms with movements in a horizontal plane. The joining means (1.6.2) in the form of "L", have a rotation along a vertical axis which is what gives a degree of freedom to the armrest (1.6) with movements in a horizontal plane.
Los medios de fijación (1.6.1) bloquean la posición seleccionada a lo largo del brazo horizontal de la "L" de los medios de unión (1.6.2) manteniendo la posibilidad de giro en el plano horizontal. The fixing means (1.6.1) block the selected position along the horizontal arm of the "L" of the joining means (1.6.2) while maintaining the possibility of rotation in the horizontal plane.
Se dispone de un movimiento longitudinal a lo largo del brazo horizontal de la "L" cuando se liberan los medios de fijación (1.6.1), permitiendo cierto grado de extensión de los brazos del paciente sin afectar la capacidad de giro, en cuyo caso el paciente puede abrir o cerrar los brazos siempre rodeando la región frente a su cara de modo que se mantiene el acceso visual. El apoyo para el pecho (1.10) permite descansar la carga del tronco del paciente debida a su ligera inclinación hacia adelante. Esta inclinación hacia adelante reduce la curvatura de las vértebras del cuello para que la cara alcance la posición final con la cara hacia abajo. There is a longitudinal movement along the horizontal arm of the "L" when the fixing means (1.6.1) are released, allowing a certain degree of extension of the patient's arms without affecting the turning capacity, in which case The patient can always open or close the arms surrounding the region in front of his face so that visual access is maintained. The chest support (1.10) allows the patient's trunk load to rest due to its slight forward inclination. This forward tilt reduces the curvature of the neck vertebrae so that the face reaches the final position with the face down.
El reposacabezas (1.7), en este ejemplo de realización, está configurado en forma aproximada como un arco de herradura con una abertura (1.7.1) interior, acolchado como todos los apoyos directamente en contacto con el cuerpo del paciente, de forma que el apoyo en la cara se produce en una región perimetral dejando libre la nariz para poder respirar y también los ojos para poder tener acceso visual al soporte (1.8.1) para mantener objetos. The headrest (1.7), in this exemplary embodiment, is roughly configured as a horseshoe arch with an inner opening (1.7.1), padded like all supports directly in contact with the patient's body, so that the Face support occurs in a perimeter region leaving the nose free to breathe and also the eyes to have visual access to the support (1.8.1) to hold objects.
El reposacabezas (1.7) está unido a la columna principal (1.8) por medio de unos medios de fijación (1.7.2) que permiten el ajuste del grado de inclinación del reposacabezas (1.7). La variación de la inclinación del reposacabezas (1.7) permite también reducir la curvatura de las vértebras cervicales del paciente, aunque es necesario en uso tener la precaución de que la posición de la cara sea la más cercana a la posición boca abajo. Esta variación de la inclinación debe ser coordinada con la posición del soporte (1.8.1) para mantener objetos para así no perder el acceso visual de éste último. The headrest (1.7) is connected to the main column (1.8) by means of fixing means (1.7.2) that allow the adjustment of the degree of inclination of the headrest (1.7). The variation of the inclination of the headrest (1.7) also allows reducing the curvature of the cervical vertebrae of the patient, although it is necessary in use to take care that the position of the face is closest to the upside down position. This variation of the inclination must be coordinated with the position of the support (1.8.1) to maintain objects so as not to lose the visual access of the latter.
El soporte (1.8.1) para mantener objetos está unido a la columna principal (1.8) mediante una estructura intermedia (1.8.1.3) formada principalmente por dos barras paralelas vinculadas entre sí donde esta estructura intermedia está en un lado unida de forma pivotante mediante unos primeros medios de fijación (1.8.1.1) a la columna principal (1.8), y en el lado opuesto unida de forma pivotante mediante unos segundos medios de fijación (1.8.1.2) a una base (1.8.2) de apoyo para mantener los objetos a ser observados por el paciente. The support (1.8.1) for holding objects is connected to the main column (1.8) by an intermediate structure (1.8.1.3) formed mainly by two parallel bars linked to each other where this intermediate structure is on a pivotally joined side by first fixing means (1.8.1.1) to the main column (1.8), and on the opposite side pivotally connected by means of second fixing means (1.8.1.2) to a support base (1.8.2) to maintain the objects to be observed by the patient.
La base (1.8.2) en este ejemplo de realización, está formada por una placa en forma de "L" que evita la caída de los objetos cuando se encuentra inclinada. La combinación de los dos giros respecto de ejes paralelos en los primeros y segundos medios de fijación (1.8.1.1, 1.8.1.2) permite modificar en altura la posición de la base (1.8.2), la separación respecto de la columna principal (1.8) y también su inclinación. En el ejemplo de realización mostrado en la figura 1 se muestra una cinta (C) que sustenta el soporte (1.8.1) a una determinada altura ya que esta cinta (C) está fijada superiormente a la columna principal (1.8). Según otro ejemplo de realización, la unión entre la base (1.8.2) y el soporte (1.8.1) se lleva a cabo mediante tornillos que entran en un alojamiento ranurado de tal modo que la ranura permite la fijación definitiva a lo largo de una determinada línea y por lo tanto a distintas alturas. Esta base (1.8.2) permite por ejemplo mantener un libro para que el paciente pueda leerlo mientras se encuentra apoyado según exige la terapia. The base (1.8.2) in this exemplary embodiment is formed by an "L" shaped plate that prevents objects from falling when it is tilted. The combination of the two turns with respect to parallel axes in the first and second fixing means (1.8.1.1, 1.8.1.2) allows to modify in height the position of the base (1.8.2), the separation with respect to the main column ( 1.8) and also its inclination. In the example of embodiment shown in Figure 1, a tape (C) is shown that supports the support (1.8.1) at a certain height since this tape (C) is fixed superiorly to the main column (1.8). According to another example of embodiment, the connection between the base (1.8.2) and the support (1.8.1) is carried out by means of screws that enter a grooved housing such that the groove allows the definitive fixation along a certain line and therefore at different heights. This base (1.8.2) allows for example to keep a book so that the patient can read it while being supported as required by therapy.
Según el ejemplo de realización que se muestra en esta misma figura 1, la base (1.8.2) tiene un conjunto (1.9) de espejos abisagrados que permiten tener acceso visual a un elemento situado frente al paciente aunque este mantenga la posición con la cabeza hacia abajo. Un ejemplo de uso es ver la televisión. La televisión requiere de un punto de observación frontal. La combinación de los dos espejos, mediante doble reflexión, permite dirigir la imagen a la posición de la cara del paciente desde donde tiene acceso visual. Esta doble reflexión se muestra mediante línea discontinua siguiendo la visual indicada como V. El conjunto (1.9) de espejos abisagrados requiere poder modificar la inclinación de la base (1.8.2) así como el grado de apertura para que el eje visual vertical no sea tapado por el espejo superior y a su vez la orientación se adapte a la posición y altura particular a la que se encuentra la televisión. Si bien la base (1.8.2) dispone de los medios de regulación de altura e inclinación descritos, el conjunto (1.9) de espejos también admite la variación de inclinación del plano de un espejo respecto del otro. La estructura del conjunto (1.9) de espejos es como sigue. El conjunto (1.9) de espejos, tal y como muestra la figura 2, dispone de una primera hoja (1.9.1) y una segunda hoja (1.9.2) abisagradas entre sí donde cada una de las hojas dispone de un espejo: la primera hoja (1.9.1) comprende un primer espejo (1.9.1.1) y la segunda hoja (1.9.2) dispone de un segundo espejo (1.9.2.1), ambos espejos (1.9.1.1, 1.9.2.1) situados en las caras interiores y con la parte reflectante hacia el interior del conjunto abisagrado. En este ejemplo de realización, al menos uno de los espejos (1.9.2.1) dispone de resaltes (1.9.2.2) flexibles para que, en el caso de cerrar el conjunto (1.9) de espejos abisagrados no se dañe un espejo (1.9.1.1) contra el otro (1.9.2.1). According to the example of embodiment shown in this same figure 1, the base (1.8.2) has a set (1.9) of hinged mirrors that allow visual access to an element located in front of the patient even if he maintains the head position down. An example of use is watching television. Television requires a frontal observation point. The combination of the two mirrors, through double reflection, allows the image to be directed to the position of the patient's face from where he has visual access. This double reflection is shown by a dashed line following the visual indicated as V. The set (1.9) of hinged mirrors requires to be able to modify the inclination of the base (1.8.2) as well as the degree of opening so that the vertical visual axis is not covered by the upper mirror and at the same time the orientation adapts to the particular position and height at which the television is located. Although the base (1.8.2) has the height and inclination adjustment means described, the set (1.9) of mirrors also admits the variation in inclination of the plane of one mirror with respect to the other. The structure of the set (1.9) of mirrors is as follows. The set (1.9) of mirrors, as shown in Figure 2, has a first sheet (1.9.1) and a second sheet (1.9.2) hinged together where each of the sheets has a mirror: The first sheet (1.9.1) comprises a first mirror (1.9.1.1) and the second sheet (1.9.2) has a second mirror (1.9.2.1), both mirrors (1.9.1.1, 1.9.2.1) located in the interior faces and with the reflective part towards the inside of the hinged assembly. In this exemplary embodiment, at least one of the mirrors (1.9.2.1) has flexible projections (1.9.2.2) so that, in the case of closing the set (1.9) of mirrors hinges do not damage a mirror (1.9.1.1) against the other (1.9.2.1).
Igualmente, en este ejemplo de realización el abisagrado se produce en dos puntos de unión donde en cada punto de unión, la primera hoja (1.9.1) tiene un primer tramo tubular (1.9.1.2) y la segunda hoja (1.9.2) tiene un segundo tramo tubular (1.9.2.3) unidos por un conjunto tornillo (1.9.3)-tuerca (1.9.4), con tuerca autoblocante, donde en todos los puntos de unión la orientación formada por el primer tramo tubular (1.9.1.2) y el segundo tramo tubular (1.9.2.3) es el mismo. El que la orientación y orden al que dan lugar el primer tramo tubular (1.9.1.2) y el segundo tramo tubular (1.9.2.3) sea el mismo tiene como efecto técnico que experimentalmente se ha observado que es posible mantener el apriete adecuado para permitir modificar la abertura del conjunto (1.9) de espejos y a la vez que este apriete no se reduzca con el uso. Si el apriete es excesivo no sería posible modificar a mano el grado de apertura del conjunto (1.9) abisagrado y por otro lado, si el apriete es insuficiente la segunda hoja (1.9.2) dispuesta superiormente no se sujetaría y el conjunto abisagrado se cerraría impidiendo al paciente observar objetos dispuestos frontalmente. Likewise, in this exemplary embodiment, the hinge is produced at two junction points where at each junction point, the first sheet (1.9.1) has a first tubular section (1.9.1.2) and the second sheet (1.9.2) It has a second tubular section (1.9.2.3) joined by a screw assembly (1.9.3) - nut (1.9.4), with self-locking nut, where at all points of attachment the orientation formed by the first tubular section (1.9. 1.2) and the second tubular section (1.9.2.3) is the same. The fact that the orientation and order to which the first tubular section (1.9.1.2) and the second tubular section (1.9.2.3) give rise is the same has the technical effect that experimentally it has been observed that it is possible to maintain adequate tightening to allow modify the opening of the set (1.9) of mirrors and at the same time that this tightening is not reduced with use. If the tightening is excessive it would not be possible to modify by hand the degree of opening of the hinged assembly (1.9) and on the other hand, if the tightening is insufficient the second sheet (1.9.2) arranged above would not be held and the hinged assembly would close preventing the patient from observing objects arranged frontally.
La figura 3 muestra el mismo objeto de la figura 2 solo que en posición cerrada y vista desde la base formada por la primera hoja (1.9.1). Esta hoja (1.9.1), así como la segunda hoja (1.9.2) está múltiplemente perforada para aligerar el peso y también facilitar la unión por encolado con el espejo (1.9.1.1, 1.9.2.1). Figure 3 shows the same object of Figure 2 only in the closed position and seen from the base formed by the first sheet (1.9.1). This sheet (1.9.1), as well as the second sheet (1.9.2) is multiple perforated to lighten the weight and also facilitate bonding by gluing with the mirror (1.9.1.1, 1.9.2.1).
En esta misma primera hoja (1.9.1) que actúa de base del conjunto (1.9) abisagrado hay en las esquinas resaltes antideslizantes (1.9.1.4) para el apoyo sobre la base (1.8.2) del soporte para objetos. In this same first sheet (1.9.1) that acts as the base of the hinged assembly (1.9) there are in the corners non-slip projections (1.9.1.4) for the support on the base (1.8.2) of the support for objects.
