Description

CAMA CONVERTIBLE EN DISPOSITIVO PARA PRONACION BED CONVERTIBLE INTO PRONATION DEVICE
Ámbito Técnico de aplicación del invento: [0001] El presente invento halla su campo de aplicación en la técnica de la pronación, la cual permite variar la movilidad diafragmática del paciente postrado en una cama y sin capacidad autónoma de desplazamientos del cuerpo, permitiendo la mejora en la ventilación y aseo del cuerpo del paciente, a la vez que impide la formación de las temidas escaras y la creación de agudas infecciones pulmonares. Technical scope of application of the invention: [0001] The present invention finds its field of application in the pronation technique, which allows varying the diaphragmatic mobility of the bedridden patient without autonomous body movement capacity, allowing improvement in the ventilation and cleaning of the patient's body, while preventing the formation of the dreaded bedsores and the creation of acute lung infections.
[0002] Efectivamente, cuando un paciente resulta inmóvil y postrado en una cama, tal como los que sufren desde parálisis corporal hasta Síndrome de Distress Respiratorio Agudo, si el paciente es mantenido en una única posición, al corto tiempo se produce la aparición de las escaras, y el aplastamiento parcial de las celdas pulmonares puede traer aparejado neumonías y otras peligrosas infecciones en las vías respiratorias. [0002] Indeed, when a patient is immobile and bedridden, such as those suffering from body paralysis to Acute Respiratory Distress Syndrome, if the patient is kept in a single position, the appearance of the bedsores, and partial crushing of lung cells can lead to pneumonia and other dangerous respiratory tract infections.
[0003] En particular, los pacientes con asistencia respiratoria mecánica se ven beneficiados con las maniobras de pronación que consiste en colocarlo en posición de decúbito lateral 20Q y decúbito prono, es decir boca abajo, con la cabeza girada de lado. [0003] In particular, patients with mechanical ventilation benefit from pronation maneuvers, which consists of placing them in a 20 Q lateral decubitus position and prone decubitus, that is, face down, with the head turned to the side.
[0004] Es por lo tanto necesario, para el correcto cuidado del paciente, que el cuerpo del mismo sea rotado sobre su eje varias veces en el dia, sin hablar del aseo, y de la necesidad de evacuación fisiológica del paciente, a menudo aunque no necesa-riamente, en estado de coma o coma inducido. [0005] Frente a un paciente en tal estado, postrado en una cama por ejemplo en terapia intensiva o intermedia, tradicionalmente la rotación del cuerpo dal paciente debe ser asistida por un equipo de no menos de cuatro personas, generalmente seis personas entre médicos y enfermería, es decir personal altamente calificado que debe trabajar en perfecta coordinación entre las funciones de control y de ejecución de la rotación, operaciones que implican cubrir y envolver la paciente con sábanas y una vez asegurado, con sumo cuidado hacerlo girar sobre su eje longitudinal, para luego retirar las sabanas. Estas operaciones son usualmente efectuadas cada seis horas, lo que implica girar o rotar el cuerpo cuatro veces al día. [0004] It is therefore necessary, for the correct care of the patient, that the body of the same is rotated on its axis several times a day, not to mention the toilet, and the need for physiological evacuation of the patient, often although not necessarily, in a coma or induced coma. [0005] Faced with a patient in such a state, bedridden for example in intensive or intermediate therapy, traditionally the rotation of the body of the patient must be assisted by a team of no less than four people, generally six people between doctors and nurses , that is, highly qualified personnel who must work in perfect coordination between the functions of control and execution of the rotation, operations that involve covering and wrapping the patient with sheets and once secured, with great care, rotate it on its longitudinal axis, to then remove the sheets. These operations are usually performed every six hours, which involves turning or rotating the body four times a day.
Estado anterior del arte: Previous state of the art:
[0006] Para facilitar estas operaciones, en el arte previo se reconocen algunas construcciones que definen camas capaces de retener al paciente y lograr su rotación según su eje longitudinal, o bien variar el Angulo del tronco con respecto de las piernas, elevando el torso, o bien las piernas. [0006] To facilitate these operations, the prior art recognizes some constructions that define beds capable of retaining the patient and achieving their rotation along their longitudinal axis, or else varying the Angle of the trunk with respect to the legs, raising the torso, or the legs.
[0007] La patente CN 110584911 A enseña una cama de pronación la cual dispone de plano rígidos articulados de manera independiente. Este documento si bien permite la rotación parcial del cuerpo del paciente, no resuelve el problema e colocar al mismo boca abajo, es decir, girarlo 118Q sobre su eje y la cama no rota, solo permite la elevación de segmentos en los laterales de la misma. [0007] CN 110584911 A patent teaches a pronation bed which has independently articulated rigid planes. Although this document allows partial rotation of the patient's body, it does not solve the problem of placing the patient face down, that is, turning him 118 Q on its axis and the bed does not rotate, it only allows the elevation of segments on the sides of the herself.
[0008] El documento CN 203138904 U ilustra otra cama de pronación, consistente en un plano rígido sobre el cual reposa el paciente, asegurado a dicho plano y es rotado hasta 180Q junto a dicho plano de apoyo, con el resultado que el paciente que boca abajo pero oculto por dicho plano, lo cual impide toda operación de limpieza y curación del dorso del mismo. Es decir, esta realización solo es efectiva en rotar el cuerpo del paciente, pero con el agravante que el mismo queda colgado boca abajo de las correas o cintas de retención, o bien de una envuelta semicilíndrica que a modo de capsula lo contiene, resultando imposible el acceso al cuerpo del paciente cuando resulta pronado. [0008] Document CN 203138904 U illustrates another pronation bed, consisting of a rigid plane on which the patient rests, secured to said plane and is rotated up to 180 Q next to said support plane, with the result that the patient is face down but hidden by said plane, which prevents any cleaning and healing operation of the back of the same. That is, this embodiment is only effective in rotating the patient's body, but with the aggravation that it is hanging upside down from the retention straps or tapes, or from a semi-cylindrical envelope that contains it as a capsule, making it impossible access to the patient's body when pronated.
[0009] El Modelo de Utilidad CN 209059728 U presenta una estructura con dos testeros o extremos consistente en respectivos plano verticales. A dichos planos se vincula un primer bastidor horizontal que presenta la particularidad de rotar sobre un eje longitudinal. Al primer bastidor se dispone paralelo un segundo bastidor y entre ambos bastidores se sitúa y retiene al paciente, siendo el primer bastidor asportable cuando finaliza la pronación lo cual permite el acceso al cuerpo del paciente así rotado. Esta construcción es útil para girar el cuerpo del paciente pero carece de protección lateral, con lo cual no puede llegar a conformar una cama propiamente dicha. [0009] The CN 209059728 U Utility Model presents a structure with two ends or ends consisting of respective vertical planes. A first horizontal frame is linked to said planes, which has the particularity of rotating on a longitudinal axis. A second frame is arranged parallel to the first frame and between both frames the patient is positioned and retained, the first frame being grippable when pronation ends, which allows access to the body of the patient thus rotated. This construction is useful for turning the patient's body but lacks lateral protection, which means that it cannot form a proper bed.
[0010] La publicación US 2002/0138906 A1 , de Bartlett, enseña una cama d pronación que presenta una estructura en cuyos extremos se sitúan dos aros de circunferencia verticales ya paralelos. A esto aros se vincula una cama la cual gira sobre las pistas proporcionadas por dichos aros, y el paciente es retenido por una serie de brazos acolchados selectivamente rebatibles. El defecto de esta realización es que, aparte de presentar una estructura de elevada complejidad y muy elevado costo, el paciente al quedar poca abajo queda suspendido asentando contra los referidos brazos acolchados y el cuerpo queda oculto por la cama sobre la cual originalmente descansaba. Retirar el colchón de apoyo original es factible, pero es una operación dificultada por la presencia de los citados brazos rebatibles. [0010] Publication US 2002/0138906 A1, by Bartlett, teaches a pronation bed that has a structure at the ends of which two parallel vertical circumferential rings are located. To these rings is linked a bed which rotates on the tracks provided by said rings, and the patient is retained by a series of selectively folding padded arms. The defect of this embodiment is that, apart from presenting a highly complex structure and Very high cost, the patient being left low is suspended, settling against the referred padded arms and the body is hidden by the bed on which it originally rested. Removing the original support mattress is feasible, but it is an operation made difficult by the presence of the aforementioned folding arms.
[0011] La patente US 6.701.553, a Barry D. Hand, más que una cama de pronación, es un dispositivo para la pronación del paciente, el cual puede ser llevado hasta la misma sobre una especial camilla la cual es asegurada al bastidor con capacidad de rotación axial sostenido por dos estructuras en cada extremo. Una vez asegurada la camilla con el paciente, el mismo es retenido por medios acolchados, y producida la rotación, una colchoneta inferior es elevable de modo que el paciente repose sobre la misma y la camilla es retirada. Este dispositivo de pronación no conforma un cama para el paciente, de modo que el mismo debe ser trasladado desde su lugar de reposo hasta el dispositivo, sobre la camilla espacial arriba citada. [0011] US patent 6,701,553, to Barry D. Hand, more than a pronation bed, is a device for the pronation of the patient, which can be carried to the same on a special stretcher which is secured to the frame with axial rotation capacity supported by two structures at each end. Once the stretcher is secured with the patient, it is retained by padded means, and when the rotation occurs, a lower mat is liftable so that the patient rests on it and the stretcher is removed. This pronation device does not form a bed for the patient, so that it must be transferred from its resting place to the device, on the space table mentioned above.
[0012] El documento US 2002/0016994 muestra otro dispositivo de pronación, el cual es de construcción muy compleja y de costo elevado. Consta de una base con un asiento o pista semicircular sobre la cual asienta una camilla específicamente diseñada para acoplarse a este dispositivo. La camilla se eleva en una columna y el paciente es llevado en contacto con una colchoneta superior retenida por una placa horizontal que tiene solidaria un cuero semicircular, el cual acopla con la pista inferior y permite el giro de 180Q sobre su eje. Se observa que este dispositivo de pronación no puede por su complejidad constituir una cama donde reposa habitualmente el paciente, el cual debe ser transportado desde su cama a este dispositivo. [0012] Document US 2002/0016994 shows another pronation device, which is of very complex construction and high cost. It consists of a base with a semicircular seat or track on which a stretcher specifically designed to be attached to this device sits. The stretcher is raised on a column and the patient is brought into contact with an upper mat held by a horizontal plate that is attached to a semicircular leather, which couples with the lower track and allows 180 Q rotation on its axis. It is observed that this pronation device cannot, due to its complexity, constitute a bed where the patient usually rests, which must be transported from his bed to this device.
[0013] La patente de Corea KR 2001 10071589 (A) es otra construcción ad hoc para pronación, pero no constituye una cama de reposo habitual del paciente. Esta estructura es también compleja y costosa y comprende una base con ruedas, con un cabezal en el cual es acoplado giratoriamente en voladizo un par de largueros horizontales que definen un bastidor en forma de horquilla, la cual se acopla una camilla específicamente diseñada. Presenta lateralmente medios acolchados articuladamente pivotantes sobre el plano de la camilla que inmovilizan al paciente y permite su giro de 180Q. Esta realización no resulta apta para tratamientos de aseos o intervenciones efectuadas al paciente sobre esta misma construcción, [0013] The Korean patent KR 2001 10071589 (A) is another ad hoc construction for pronation, but it does not constitute a usual patient bed. This structure is also complex and expensive and comprises a base with wheels, with a head in which a pair of horizontal beams defining a fork-shaped frame is rotatably attached to which a specifically designed stretcher is attached. It presents laterally articulated padded means pivoting on the plane of the stretcher that immobilizes the patient and allows its 180 Q rotation. This embodiment is not suitable for toilet treatments or interventions carried out on the patient on this same construction,
[0014] La patente US 6.282.736 a Barry D. Hand, ampara una construcción algo semejante a la anterior: consta de una base y un cabezal en el cual en voladizo asienta girable sobre su eje una cama, sobre la cual se coloca el paciente, el cual es aprisionado por una tapa que se cierra sobre la cama, lo cual permite el giro del paciente hasta 180Q. El paciente debe ser luego retirado, ya pronado, y reposado sobre una camilla suplementaria. Resulta entonces que esta última construcción, de confección costosa no constituye la cama donde habitualmente reposa el paciente y solo es útil para pronaciones. [0014] US patent 6,282,736 to Barry D. Hand, covers a construction somewhat similar to the previous one: it consists of a base and a head in which a cantilevered bed sits rotatable on its axis, on which the patient, which is trapped by a lid that closes on the bed, which allows the patient to rotate up to 180 Q. The patient must then be removed, already pronated, and rested on an additional stretcher. It turns out then that this last construction, which is expensive to manufacture, does not constitute the bed where the patient usually rests and is only useful for pronation.
[0015] Resulta entonces conocido en el arte previo disponer de una estructura la cual presenta dos componentes verticales, distanciados y paralelos entre sí, ambos vinculados solidarios a una estructura que los vincula; entre ambos componentes verticales se dispone una segunda estructura horizontal que define un bastidor, hallándose dicho bastidor dispuesto giratorio respecto a un eje longitudinal horizontal a media altura respecto a dichos dos componentes verticales. [0015] It is then known in the prior art to have a structure which has two vertical components, spaced and parallel to each other, both linked in solidarity with a structure that links them; Between both vertical components a second horizontal structure is provided that defines a frame, said frame being arranged rotatable with respect to a horizontal longitudinal axis at half height with respect to said two vertical components.

Descripción detallada del presente invento: Detailed description of the present invention:
[0038] A efectos de lograr concretar un ejemplo de realización preferido del presente invento, los citados dibujos, con el apoyo de la descripción de los mismos dada a continuación, lo ilustran en detalle, debiendo interpretarse este ejemplo de realización como una de las tantas posibles construcciones del invento, por lo que no corresponde asignarle ningún valor limitativo al mismo, incluyéndose dentro del ámbito de protección del invento los posibles medios equivalentes a los ilustrados; siendo la amplitud del presente invento determinado por la primera reivindicación adjunta en el capítulo de Reivindicaciones correspondiente. Asimismo, en estas Figuras, las mismas referencias identifican medios iguales y/o equivalentes. [0039] En las figuras 1 y 2, se identifica con la referencia genérica (10) al componente vertical de un extremo de la cama, siendo (20) la referencia genérica del componente vertical opuesto. Dichos componentes verticales constituyen el testero y extremo opuesto de la cama, y pueden consistir en una placa resistente, o bien en una estructura tubular, preferentemente de perfiles de sección cuadrangular. En la construcción ilustrada se ha optado por mostrar ambos testeros o componentes verticales (10, 20) con una estructura tubular. [0038] In order to achieve a preferred embodiment of the present invention, the aforementioned drawings, with the support of the description of the same given below, illustrate it in detail, this embodiment should be interpreted as one of many possible constructions of the invention, therefore it is not appropriate to assign any limiting value to it, including possible means equivalent to those illustrated within the scope of protection of the invention; the scope of the present invention being determined by the first claim attached in the corresponding Claims chapter. Also, in these Figures, the same references identify the same and / or equivalent means. [0039] In Figures 1 and 2, the generic reference (10) is identified to the vertical component of one end of the bed, with (20) being the generic reference of the opposite vertical component. Said vertical components constitute the front end and opposite end of the bed, and may consist of a resistant plate, or a tubular structure, preferably of quadrangular section profiles. In the illustrated construction, it has been chosen to show both end faces or vertical components (10, 20) with a tubular structure.
[0040] Ambos componentes (10, 20) se disponen paralelos y vinculados a los extremos de un bastidor (30) mecánicamente resistente vinculado perpendicular a estos y en adyacencia de los extremos inferiores de cada componente vertical, de modo que de conformar una estructura de cama, idealmente dotada de ruedas (1 ) en las esquinas inferiores de cada componentes vertical. A mero titulo de ejemplo no limitante, las dimensiones del largo de la cama es de 2400cms, siendo su altura medida en el extremo superior de cada placa vertical o testero de 1500cms, y con un ancho de cama de 110Ocms. [0040] Both components (10, 20) are arranged parallel and linked to the ends of a mechanically resistant frame (30) linked perpendicular to these and adjacent to the lower ends of each vertical component, so as to form a structure of bed, ideally equipped with wheels (1) in the lower corners of each vertical component. As a mere non-limiting example, the dimensions of the length of the bed is 2400cms, being its height measured at the top end of each vertical plate or end wall of 1500cms, and with a bed width of 110Ocms.
[0041] En la Figura 3 se observa la estructura de cama propiamente dicha, la cual convencionalmente presenta pares de columnas (11 ) verticales, que se unen a un travesaño inferior (12) y a otro superior (13) conformando uno de los componentes verticales o testeros. De la misma manera en el extremo opuesto se tiene a otro componente vertical (20) o testero, conformado por columnas verticales (21 ), inferiormente vinculadas por un travesaño inferior (22) y una placa superior (23) que oficia de travesaño. En la misma figura se observa la existencia de un mecanismo de giro (40) compuesto por un tren de engranajes (no ilustrados) dispuestos dentro de una caja o envuelta (41 ), engranajes que son manualmente accionados por una manija (42) y que se asocian a un reductor, del cual sobresale el eje (43). El bastidor (30) mecánicamente resistente es de estructura convencional y conocida, con cuadernas en las esquinas para consolidar la fijación inmóvil de los componentes de la estructura de cama. [0041] Figure 3 shows the bed structure itself, which conventionally has pairs of vertical columns (11), which are joined to a lower cross member (12) and an upper cross member (13) forming one of the vertical components or end walls. In the same way, at the opposite end there is another vertical component (20) or head, made up of vertical columns (21), linked below by a lower crossbar (22) and an upper plate (23) that acts as a crossbar. The same figure shows the existence of a turning mechanism (40) composed of a gear train (not illustrated) arranged inside a box or casing (41), gears that are manually operated by a handle (42) and that are associated with a reducer, from which the shaft (43) projects. The mechanically resistant frame (30) is of conventional and known structure, with frames in the corners to consolidate the immobile fixation of the components of the bed frame.
[0042] La Figura 4 muestra en detalle los componentes de la Figura 3, con el agregado de la estructura (50) pivotante sobre su eje longitudinal vinculada a dichos componentes verticales (10, 20). Dicha estructura pivotante (50) gira mandada por el extremo de eje (43), y su extremo opuesto gira en un acople (no visible) practicado en la cara interna del componente vertical (20). Convenientemente el eje de giro es paralelo al bastidor (30) en la mediana geométrica del mismo y se sitúa en adyacencias del extremo superior de (10, 20). Dicha estructura pivotante (50) se compone por una pieza trasversal (51 ) dispuesta vinculada pivotante respecto al componente vertical (10) y adyacente al mismo, mientras que en el extremo opuesto, tenemos una segunda pieza trasversal (52), adyacente a la cara interna de (20). La longitud de (51 , 52) es sustancialmente igual al ancho del bastidor (30) y a cada lado de cada extremo de dichas dos piezas trasversales se dispone una charnela (53) en forma de “T” acostada de modo que (ver la Figura 5) de modo que tramo intermedio (53a) se disponga vinculado contra la ambas caras de cada extremo de (51 , 52), mientras que el brazo de la cruz (53b) de la “T” sobresale libres desde dichos extremos de las piezas trasversales. [0043] Siempre considerando las Figuras 4 y 5, se observa que entre el par de los citados brazos (53b) se define un alojamiento libre (54). Equidistante del eje de (51 , 52) se conforman respectivas articulaciones (55) en donde articulan pares de piezas en “L” de manera tal que entre un mismo par de tramos verticales (56a) de la “L” se aprisiona y vincula un montante (57), mientras que el tramo horizontal (56b) de dicha “L” se vincula a la articulación respectiva (55). En la Figura 5 se ha omitido las piezas en ”L” del montante inferior, para ¡lustra la forma de la articulación (55), per ose entiende que dicho montante inferior (57) se halla articulado en (55) de manera similar al superior, tal como ha sido aquí ilustrado. [0044] Cada montante (57) ( ver la Figura 4) se halla vinculado con el montante opuesto en un mismo lateral de la cama por medio de un larguero (58), conformando respectivos pórticos superior e inferior. Es decir, cada pórtico es formado por dos montantes (57) paralelos a las piezas trasversales (51 , 52) y un larguero perpendicular (58), dispuesto paralelo al piso, resultando los extremos de cada montante articuladamente pivotante a los extremos de la respectiva pieza trasversal. [0042] Figure 4 shows in detail the components of Figure 3, with the addition of the pivoting structure (50) on its longitudinal axis linked to said vertical components (10, 20). Said pivoting structure (50) rotates controlled by the end of the shaft (43), and its opposite end rotates in a coupling (not visible) made on the internal face of the vertical component (20). Conveniently the axis of rotation is parallel to the frame (30) in the geometric median thereof and is located adjacent to the upper end of (10, 20). Said pivoting structure (50) is made up of a cross piece (51) arranged pivotally linked with respect to the vertical component (10) and adjacent to it, while at the opposite end, we have a second cross piece (52), adjacent to the face internal of (20). The length of (51, 52) is substantially equal to the width of the frame (30) and on each side of each end of said two transversal pieces a hinge (53) is arranged in the shape of a "T" lying flat so that (see Figure 5) so that intermediate section (53a) is arranged linked against both faces of each end of (51, 52), while the arm of the cross (53b) of the "T" protrudes free from said ends of the pieces transversal. [0043] Always considering Figures 4 and 5, it is observed that between the pair of said arms (53b) a free housing (54) is defined. Equidistant from the axis of (51, 52), respective joints (55) are formed where they articulate pairs of pieces in "L" in such a way that between the same pair of vertical sections (56a) of the "L" a upright (57), while the horizontal section (56b) of said "L" is linked to the respective joint (55). In Figure 5, the "L" pieces of the lower post have been omitted, to illustrate the shape of the joint (55), but it is understood that said lower post (57) is articulated at (55) in a similar way to superior, as illustrated here. Each upright (57) (see Figure 4) is linked to the opposite upright on the same side of the bed by means of a beam (58), forming respective upper and lower portals. That is to say, each gantry is formed by two posts (57) parallel to the cross pieces (51, 52) and a perpendicular beam (58), arranged parallel to the floor, with the ends of each post being pivotally articulated to the ends of the respective cross piece.
[0045] Es de notar (ver Fig. 4) que dichos pórticos laterales a cada lado de la cama, cuando se encuentran en posición vertical, debido a la citada articulación en “L” apoyan contra el extremo de la respectiva pieza transversal (51 , 52), de modo que el extremo inferior (59) de cada montante determina un fin de carrea en el desplazamiento angular para permanecer en posición vertical. Asimismo, es de notar que el par d pórticos de un mismo lado, cuando en la posición vertical ilustrada en la Figura 4, se contienen en un mismo plano vertical. [0046] Ambos pórticos sitos en un mismo lateral son selectivamente pivotantes en modo independiente desde una posición en la cual, y tal como se mención arriba, ambos pórticos de un mismo lateral se disponen verticalmente alineados y contenidos en un mismo plano vertical, hasta una posición rebatida paralela a la anterior (ver la Figura 6). A su vez, cada larguero perpendicular (58) de cada pórtico se vincula a sus pares de montantes opuestos (57) de cada pórtico a una distancia intermedia entre extremos dejando libre el extremo (60) de cada montante (57). Allí se articula a cada aportico una placa (61 , 61') (Ver Fig. 7) pivotante en toda su longitud, siendo al ancho de cada placa (61 , 61 ') igual a la mitad del ancho de la cama determinado por la dimensión trasversal de los citados componentes verticales (10, 20). [0045] It should be noted (see Fig. 4) that said side frames on each side of the bed, when they are in a vertical position, due to said "L" joint, rest against the end of the respective cross piece (51 , 52), so that the lower end (59) of each upright determines an end of stroke in the angular displacement to remain in a vertical position. Likewise, it should be noted that the pair of frames on the same side, when in the vertical position illustrated in Figure 4, are contained in the same vertical plane. [0046] Both frames located on the same side are selectively pivoting independently from a position in which, and as mentioned above, both frames on the same side are arranged vertically aligned and contained in the same vertical plane, up to a folded position parallel to the previous one (see Figure 6). In turn, each perpendicular beam (58) of each frame is linked to its pairs of opposite posts (57) of each frame at an intermediate distance between ends, leaving the end (60) of each post (57) free. There, a plate (61, 61 ') (See Fig. 7) pivoting along its entire length is articulated to each frame, the width of each plate (61, 61') being equal to half the width of the bed determined by the transversal dimension of the mentioned vertical components (10, 20).
[0047] Dichas placas (61 , 61 ') conforman selectivamente dos planos de apoyo horizontales, paralelos entre sí y separados por la suma de las longitudes de los montantes (57) los cuales preferiblemente tienen la misma longitud. Cada placa (61 , 61') se articula al extremo de (60) mediante bisagras (62) y en dicha posición horizontal se mantienen en posición y mecánicamente estables por medio de los pistones (63), las trabas de extremo (64) y los medios de enganche de seguridad (65), que traban los bordes libres (66) de cada placa con dichos bordes adosados mutuamente entre sí, conformado un plano de apoyo (Ver la Fig. 13). Convenientemente cada placa presenta medios (67) que permiten asir y maniobrar las mismas. Se debe notar que tanto los medios de asir (67) y los medios de traba (65) se ubican sobre el plano externo, es decir, en el sentido opuesto al que enfrenta la paciente. [0048] La Figura 8 nos muestra la cama de pronación del invento, con sus placas (61 , 61') en posición horizontal. En esta posición, sobre el conjunto de placas inferior (61 ') se conforma el plano mecánicamente resistente que sirve de apoyo al colchón inferior (2) sobre el cual reposa el paciente (no ilustrado). [0049] Con las placas en la misma posición, en la Figura 9 se ilustra la colocación contra el lateral de cada pórtico y sobre el colchón inferior (2) respectivas defensas laterales, entre las cuales se sitúa el paciente. La altura de estas defensas debe superar la altura del cuerpo acostado del paciente y debe ser menor a la altura que media entre el colchón (2) y el plano superior formado por las placas (61 ). [0050] La Figura 20 ilustra el próximo paso, consistente en rebatir las placas (61 )Said plates (61, 61 ') selectively form two horizontal support planes, parallel to each other and separated by the sum of the lengths of the uprights (57) which preferably have the same length. Each plate (61, 61 ') is articulated to the end of (60) by hinges (62) and in said horizontal position they are kept in position and mechanically stable by means of the pistons (63), the end locks (64) and the safety hooking means (65), which lock the free edges (66) of each plate with said edges mutually attached to each other, forming a support plane (See Fig. 13). Conveniently, each plate has means (67) that allow them to be grasped and maneuvered. It should be noted that both the gripping means (67) and the locking means (65) are located on the external plane, that is, in the opposite direction to that facing the patient. [0048] Figure 8 shows us the pronation bed of the invention, with its plates (61, 61 ') in a horizontal position. In this position, the mechanically resistant plane that supports the lower mattress (2) on which the patient rests (not illustrated) is formed on the set of lower plates (61 '). [0049] With the plates in the same position, Figure 9 illustrates the placement against the side of each gantry and on the lower mattress (2) respective side fenders, between which the patient is located. The height of these fenders must exceed the height of the patient's lying body and must be less than the height between the mattress (2) and the upper plane formed by the plates (61). [0050] Figure 20 illustrates the next step, consisting of folding the plates (61)
(ver el esquema de la Fig. 6) dejando libre desde arriba al paciente 85), y se colocan los zunchos o cintas (4) que traccionan a las defensas (3, 3') contra el colchón (29 y al mismo tiempo inmovilizan al paciente. (see the diagram in Fig. 6) leaving the patient 85 free from above), and the straps or tapes (4) are placed that pull the fenders (3, 3 ') against the mattress (29 and at the same time immobilize to the patient.
[0051] En la figura 11 se muestra la próxima etapa, consistente en disponer sobre los bordes libres de las defensas laterales (3, 3') un segundo colchón o colchoneta (6, de modo que I paciente queda ocluido dentro del recinto acolchado formado por ambos colchones y defensas laterales. [0051] Figure 11 shows the next stage, consisting of arranging on the free edges of the side fenders (3, 3 ') a second mattress or mat (6, so that I patient remains occluded within the padded enclosure formed for both mattresses and side fenders.
[0052] La Figura 12 nos muestra la última etapa de la preparación previa al giro de la cama para la pronación. En esta etapa se suben las placas y se forma el plano superior (61) y se asegura e mismo hasta lograr una plano mecánicamente resistente que presiona contra el colchón superior (6). Efectuada esta última operación, se procede a girar con la manija (42) el plano volcable hasta lograr el ángulo deseado, incluyendo un giro de 180Q, con el cual el paciente queda boca abajo y ahora descansa sobre el plano superior (61 ) y se procede retirar al plano formado por las placas (61') que ahora quedan en posición superior. [0052] Figure 12 shows us the last stage of the preparation prior to turning the bed for pronation. In this stage the plates are raised and the upper plane (61) is formed and it is secured until a mechanically resistant plane is achieved that presses against the upper mattress (6). Once this last operation has been carried out, the tipping plane is rotated with the handle (42) until the desired angle is achieved, including a 180 Q turn, with which the patient remains in the mouth. down and now rests on the upper plane (61) and proceeds to withdraw to the plane formed by the plates (61 ') that now remain in the upper position.
[0053] Tornando sobre la Figura 6, la misma esquematiza de manera muy simplificada el movimiento que efectúa cada uno de los pórticos con su placa, de modo que (65a') indica la posición de la bisagra una vez rebatido el pórtico con el montante (57) ahora girado en (57'). Turning on Figure 6, it schematizes in a very simplified way the movement carried out by each of the gantries with its plate, so that (65a ') indicates the position of the hinge once the gantry is folded with the upright. (57) now turned to (57 ').
[0054] Concretamente, mediante el presente invento se logra el resultado inédito que el paciente pueda descansar en su propia cama y que la misma selectivamente se puede convertir convierte en un dispositivo de pronación, con lo cual se evita tener que desplazar al paciente y al mismo tiempo girar su cuerpo según las indicaciones de los facultativos que lo atienden, siendo este un resultado inédito que no se logra con las construcciones del arte previo. Al mismo tiempo, otra de las ventajas del invento es que la pronación, efectuada con la mayor seguridad es lograda con presencia d un mínimo de personal, solo un par de personas. [0054] Specifically, the present invention achieves the unprecedented result that the patient can rest in his own bed and that it can be selectively converted into a pronation device, thereby avoiding having to move the patient and the patient. At the same time, turn his body according to the indications of the doctors who attend him, this being an unprecedented result that cannot be achieved with the constructions of the previous art. At the same time, another advantage of the invention is that pronation, carried out with the greatest safety, is achieved with the presence of a minimum of personnel, only a couple of people.
