El documento ES1139457U da a conocer un cartucho que define un recipiente cilindrico o prismático formado a partir de láminas de cartón, cerrado por su base inferior y abierto superiormente, e interiormente dividido en una pluralidad de celdas en las que depositar o insertar desechos o residuos sanitarios, por ejemplo jeringas y viales y otros residuos que puedan resultar focos de infección. Para su almacenaje y distribución, el cartucho es plegable. Se forma a partir de una lámina flexible troquelada de cartón, que define el cuerpo y la base del cartucho. La base se forma por dos semibases, de configuración conjunta acorde al perímetro que vaya adoptar el cartucho, y que definen dos solapas superpuestas y fijadas entre sí; conformando, dichas solapas, en la posición desplegada del cartucho, un tabique diametral, que queda en línea entre las superficies laterales del cuerpo del cartucho y ligeramente remetido por debajo de la base del mismo, impidiendo que se deforme o aplaste el fondo del cartucho una vez desplegado. Estas semibases están unidas a los rectángulos que darán lugar al cuerpo del cartucho mediante sendas solapas, situadas en la zona central del cartucho en posición plegada, que tienen una altura equivalente al citado tabique diametral a fin de que la base del cartucho se disponga remetida en esta altura y apoyando en ambos elementos, conjuntamente con otros apoyos periféricos definidos por varias pestañas que emergen radialmente de las dos semibases y están unidas a ellas mediante líneas de plegado. Este documento no da a conocer el uso de films plásticos recubriendo el cartucho. Si bien este cartucho resulta plegable para su almacenamiento, no lo es una vez se ha llenado el mismo. Document ES1139457U discloses a cartridge that defines a cylindrical or prismatic container formed from cardboard sheets, closed at its lower base and open at the top, and internally divided into a plurality of cells in which to deposit or insert waste or sanitary waste , for example syringes and vials and other residues that can be sources of infection. For storage and distribution, the cartridge is foldable. It is formed from a flexible die-cut sheet of cardboard, which defines the body and base of the cartridge. The base is formed by two semi-bases, with a joint configuration according to the perimeter that the cartridge will adopt, and which define two overlapping flaps and fixed to each other; these flaps forming, in the deployed position of the cartridge, a diametrical partition, which is in line between the lateral surfaces of the body of the cartridge and slightly tucked under the base thereof, preventing the bottom of the cartridge from being deformed or squashed. once deployed. These semi-bases are joined to the rectangles that will give rise to the body of the cartridge by means of two flaps, located in the central area of the cartridge in a folded position, which have a height equivalent to the aforementioned diametral partition so that the base of the cartridge is arranged tucked in. this height and resting on both elements, together with other peripheral supports defined by several flanges that emerge radially from the two semi-bases and are connected to them by folding lines. This document does not disclose the use of plastic films coating the cartridge. Although this cartridge is foldable for storage, it is not once it has been filled.
La presente invención tiene como objetivo dar a conocer un cartucho que puede ser compactado en autoclave, pero carece de las limitaciones de reducción de tamaño una vez rellenado que presentan los cartuchos anteriormente conocidos. The present invention aims to provide a cartridge that can be compacted into autoclave, but lacks the size reduction limitations upon refilling of previously known cartridges.
Más en particular, la presente invención da a conocer un cartucho para residuos médicos y hospitalarios, realizado en material laminar plegable, y que se caracteriza por que presenta forma cilindrica o prismática, que queda abierta por una de sus bases y cerrado por la otra, presentando dicho cuerpo una base que queda unida a la pared o paredes laterales del cartucho por medio de puentes, de tal manera que parte del perímetro de la base queda sin unir al cuerpo y por que el cartucho presenta una lámina termorretráctil que rodea a la citada pared o paredes laterales. More particularly, the present invention discloses a cartridge for medical and hospital waste, made of foldable laminar material, and characterized in that it has a cylindrical or prismatic shape, which is open on one of its bases and closed on the other, Said body presenting a base that is attached to the wall or side walls of the cartridge by means of bridges, in such a way that part of the perimeter of the base remains unattached to the body and because the cartridge has a heat-shrinkable sheet that surrounds the aforementioned wall or side walls.
De acuerdo con la invención, la base queda separada de la pared o paredes laterales del cartucho, lo que permite que ésta se pueda separar de la pared lateral durante la retracción de la lámina en un proceso de esterilización en autoclave. Esta separación permite una mayor compactación del cartucho puesto que facilita que la base y el cuerpo presenten comportamientos diferentes durante la compactación. Por otro lado, los puentes evitan que la base se separe tanto del resto del cuerpo que puedan salir los residuos médicos del interior del cuerpo. According to the invention, the base is separated from the side wall or walls of the cartridge, which allows the latter to be separated from the side wall during retraction of the sheet in an autoclave sterilization process. This separation allows a greater compaction of the cartridge since it facilitates that the base and the body present different behaviors during the compaction. On the other hand, the bridges prevent the base from separating so much from the rest of the body that medical waste can escape from the inside of the body.
Con objeto de facilitar la compactación, la base podrá presentar al menos una línea de plegado preferente. Preferentemente, la línea de plegado preferente recorrerá diametralmente la base, es decir, de extremo a extremo pasando por el centro geométrico de la base. Resultan conocidas diferentes maneras de implementar líneas de plegado preferente. Por ejemplo, puede debilitarse la pared de la base a lo largo de la línea. También es posible disponer una solapa o aleta perpendicular a la base a lo largo de la línea de plegado. In order to facilitate compaction, the base may have at least one preferred fold line. Preferably, the preferred fold line will run diametrically across the base, that is, from end to end passing through the geometric center of the base. Different ways of implementing preferred fold lines are known. For example, the base wall can be weakened along the line. It is also possible to arrange a flap or fin perpendicular to the base along the fold line.
De manera aún más preferente, la base quedará unida a pared lateral mediante dos puentes situados de manera opuesta uno del otro. Aún más preferentemente, dichos puentes se situarán de manera perpendicular con respecto a la citada línea de plegado preferente. Even more preferably, the base will be attached to the side wall by means of two bridges located opposite each other. Even more preferably, said bridges will be perpendicular to said preferred fold line.
Tanto la pared lateral del cartucho como la de la base estarán realizadas, preferentemente, en un material flexible, para favorecer la compactación. En una realización especialmente preferente, tanto la pared lateral como la base estarán realizadas en cartón, material que es un material plegable y flexible.Both the side wall of the cartridge and that of the base will preferably be made of a flexible material, to promote compaction. In a particularly preferred embodiment, both the side wall and the base will be made of cardboard, a material that is a foldable and flexible material.
El cartucho objeto de la presente invención se puede introducir en un autoclave para la esterilización y compresión del cartucho mediante la retracción de la lámina termorretráctil (sleeve) que rodea el cuerpo del cartucho debido al aumento de temperatura que se produce en el autoclave. En el autoclave, además, se produce la esterilización de los desechos médicos contenidos en el cartucho. The cartridge object of the present invention can be introduced into an autoclave for the sterilization and compression of the cartridge by retraction of the heat-shrinkable sheet (sleeve) that surrounds the body of the cartridge due to the increase in temperature that occurs in the autoclave. In addition, the autoclave sterilizes the medical waste contained in the cartridge.
Una vez extraído del autoclave, el cartucho y su contenido quedan contenidos y compactados, listos para su transporte a un centro de reciclado. Gracias a la esterilización producida en autoclave, los residuos médicos no resultan biológicamente contaminantes, y el cartucho protege de posibles cortes, por lo que su transporte y reciclado no precisan requerimientos especiales. Once removed from the autoclave, the cartridge and its contents are contained and compacted, ready for transport to a recycling center. Thanks to the sterilization produced in an autoclave, medical waste is not biologically contaminating, and the cartridge protects from possible cuts, so its transport and recycling do not require special requirements.
Temperaturas habituales de autoclave son de entre 80 eC y 136 eC, si bien existen autoclaves que funcionan a otras temperaturas. El material de la lámina termorretráctil que rodea el cuerpo se debe elegir para que se contraiga cuando sea sometida a las temperaturas del autoclave que se prevé sea utilizado. Puede ser un material plástico. Por sus propiedades (origen vegetal y biodegradabilidad), el poliácido láctico (PLA) es un material especialmente preferente para la lámina termorretráctil. Autoclave temperatures usual are between 80 and 136 C and C and, while there autoclaves they work at other temperatures. The material of the heat-shrinkable sheet surrounding the body must be chosen to contract when subjected to the temperatures of the autoclave that is expected to be used. It can be a plastic material. Due to its properties (plant origin and biodegradability), polyacid lactic acid (PLA) is a particularly preferred material for heat-shrink film.
El cartucho de la invención, está destinado a introducirse en el interior de un contenedor rígido, y se forma a partir de una lámina flexible, por ejemplo de cartón, convenientemente troquelada, que define el cuerpo y la base del cartucho. The cartridge of the invention is intended to be inserted inside a rigid container, and is formed from a flexible sheet, for example cardboard, suitably stamped, which defines the body and the base of the cartridge.
Preferentemente, el cuerpo presenta en su interior láminas flexibles que conforman una estructura de panal plegable. Más preferentemente, dicha estructura de panal divide el interior del cuerpo en cuatro espacios de almacenamiento. Preferably, the body has inside it flexible sheets that form a collapsible honeycomb structure. More preferably, said honeycomb structure divides the interior of the body into four storage spaces.
Esta estructura de panal plegable se fija preferentemente por el interior del cuerpo tubular del cartucho en dos puntos diametralmente opuestos situados ortogonalmente respecto a las líneas de doblez laterales del mismo. This collapsible honeycomb structure is preferably fixed inside the tubular body of the cartridge at two diametrically opposite points located orthogonally with respect to the lateral fold lines thereof.

En las figuras se ha mostrado un ejemplo de realización de cartucho para residuos médicos y hospitalarios según la presente invención. El cartucho del ejemplo presenta un cuerpo 1 de forma tubular. En el ejemplo, el cuerpo presenta forma cilindrica, si bien, perfectamente, podría presentar forma prismática, por ejemplo de planta octogonal o decagonal. El cuerpo 1 está realizado preferentemente en material reciclable. En el ejemplo mostrado, el cuerpo 1 está realizado en cartón corrugado. Como se observa, las ondas del cartón corrugado se desarrollan a lo largo de la sección transversal de la pared lateral 11 con forma cilindrica o prismática del cuerpo 1. Esta realización es preferente puesto que facilita la posterior retracción del diámetro del cartucho, a la vez que que se mantiene una buena resistencia de la pared. Como se observa en las figuras, el cuerpo 1 del ejemplo queda superiormente abierto, mientras que interiormente presenta una base 13 que impide la caída de los objetos colocados en su interior. The figures show an embodiment of a cartridge for medical and hospital waste according to the present invention. The cartridge of the example has a tubular body 1. In the example, the body has a cylindrical shape, although, perfectly, it could have a prismatic shape, for example an octagonal or decagonal plan. The body 1 is preferably made of recyclable material. In the example shown, body 1 is made of cardboard corrugated. As can be seen, the waves of the corrugated cardboard develop along the cross section of the side wall 11 with a cylindrical or prismatic shape of the body 1. This embodiment is preferred since it facilitates the subsequent retraction of the diameter of the cartridge, at the same time that good wall resistance is maintained. As can be seen in the figures, the body 1 of the example remains open at the top, while on the inside it has a base 13 that prevents the objects placed inside it from falling.
Interiormente, el cuerpo 1 está preferentemente dividido en múltiples celdas que se desarrollan longitudinalmente, es decir, paralelas al eje central o de simetría principal del cuerpo. En particular, en el ejemplo mostrado, el interior del cuerpo está dividido en cuatro de dichas celdas 121 , 122, 123, 124. Dicha división se consigue, en el ejemplo, mediante una estructura tipo panel 12 que resulta plegable que queda realizada, por ejemplo, en papel. Internally, the body 1 is preferably divided into multiple cells that develop longitudinally, that is, parallel to the central axis or of main symmetry of the body. In particular, in the example shown, the interior of the body is divided into four of said cells 121, 122, 123, 124. Said division is achieved, in the example, by means of a panel-type structure 12 that is foldable, which is made, by example, on paper.
La cara exterior del cuerpo 1 queda rodeada por una lámina 2. Dicha lámina está realizada en un material termorretráctil, es decir, un material que disminuye sus dimensiones a partir de una temperatura o rango de temperaturas determinado. El objetivo es que dicha retracción se produzca durante el proceso de esterilización en autoclave del contenido del cartucho. Un material preferente para la realización de la lámina es el poliácido láctico (PLA) y derivados. Como se observa, la lámina 2 del ejemplo presenta forma de manga. También podría presentar forma de bolsa, es decir podría cubrir al menos una de las dos bases del cuerpo 1 del cartucho, preferentemente la base 13 que queda cerrada. Igualmente, y en función de la aplicación y de los materiales y dimensiones utilizados, la altura de la lámina 2 puede ser igual, menor o superior a la de la pared lateral 11 del cuerpo 1 del cartucho. The outer face of the body 1 is surrounded by a sheet 2. Said sheet is made of a heat-shrinkable material, that is, a material that decreases its dimensions from a certain temperature or range of temperatures. The objective is that such retraction occurs during the autoclave sterilization process of the contents of the cartridge. A preferred material for the production of the sheet is polyacid lactic acid (PLA) and derivatives. As can be seen, sheet 2 of the example is in the shape of a sleeve. It could also be in the form of a bag, that is, it could cover at least one of the two bases of the body 1 of the cartridge, preferably the base 13 that remains closed. Likewise, and depending on the application and the materials and dimensions used, the height of the sheet 2 may be equal to, less than or greater than that of the side wall 11 of the body 1 of the cartridge.
En la figura 5 puede observarse un cartucho en estado plegado, y en posición invertida. En estado plegado que se muestra, el cuerpo y la lámina termorretráctil definen dos superficies laterales superpuestas delimitadas por unas líneas de plegado. Sólo una de las superficies resulta visible en la figura. En esta figura puede observarse que la base 13 queda unida a la pared lateral 11 del cuerpo a través de puentes 14. Los puentes 14 permiten que el perímetro de la pared lateral quede desacoplado de la base, lo que a su vez permite que la base pueda doblarse libremente y/o alejarse de su posición original de base durante el proceso de compactación. En la figura mostrado, los puentes 14 y dispuestos de manera enfrentada o diametralmente opuesta. Asimismo están dispuestos perpendicularmente con respecto a la línea de doblado 131 de la base. Dicha línea de doblado 131 , en combinación con los puentes 14 facilita un comportamiento diferente de la base durante la compactación. También facilita el almacenamiento de los cartuchos en disposición plana. El cuerpo 1 mostrado con la disposición de la figura 5 puede obtenerse de varias maneras. Por ejemplo, puede obtenerse por troquelado de una pieza plana que es doblada por la línea de doblado 131 y posteriormente se procede a unir, por pegado, engarce o de otra manera dos generatrices de la pared lateral del cuerpo 1. También es posible obtener la línea de doblado 131 preferente mediante pegado de dos partes de cartón. En este caso, sólo sería necesario cerrar una generatriz de la pared lateral del cuerpo. Por último, sería posible fabricar la pared lateral y la base 13 a partir de piezas troqueladas diferentes, y proceder a la unión de pared lateral y base a través de los puentes 14 mediante pegado, cosido, unión de engarce o cualquier otra. Esta alternativa presenta la ventaja de que las ondulaciones de la base pueden presentar una disposición diferente a la de la pared lateral (a diferencia de lo que ocurre en la figura 5), más concretamente las líneas de ondulación de la base podrían ser perpendiculares a las de la pared lateral del cuerpo. De esta manera se generarían, de manera automática, líneas de doblado preferente a lo largo de las generatrices longitudinales de las ondas del ondulado del cartón de la base. Una de las funciones de la base 13 es la de impedir pinchazos provocados por jeringuillas introducidas en el cartucho. No es necesario que dicho cartón sea reforzado. In figure 5 a cartridge can be seen in a folded state, and in an inverted position. In the folded state shown, the body and the heat shrinkable sheet define two superimposed side surfaces delimited by fold lines. Only one of the surfaces is visible in the figure. In this figure it can be seen that the base 13 is attached to the side wall 11 of the body through bridges 14. The bridges 14 allow the perimeter of the side wall to be decoupled from the base, which in turn allows the base can bend freely and / or move away from its original base position during the compaction process. In the figure shown, the bridges 14 and arranged opposite or diametrically opposite. They are also arranged perpendicular to the fold line 131 of the base. Said fold line 131, in combination with bridges 14, facilitates a different behavior of the base during compaction. It also makes it easy to store cartridges flat. The body 1 shown with the arrangement of figure 5 can be obtained in various ways. For example, it can be obtained by punching a flat piece that is bent by the fold line 131 and subsequently proceeding to join, by gluing, crimping or otherwise two generatrices of the side wall of the body 1. It is also possible to obtain the preferred folding line 131 by gluing two pieces of cardboard. In this case, it would only be necessary to close a generatrix of the side wall of the body. Finally, it would be possible to manufacture the side wall and the base 13 from different blanks, and proceed to join the side wall and base through the bridges 14 by gluing, stitching, crimping or any other. This alternative has the advantage that the undulations of the base can have a different arrangement than that of the side wall (unlike what happens in figure 5), more specifically the Undulating lines on the base could be perpendicular to those on the side wall of the body. In this way, preferential folding lines would be automatically generated along the longitudinal generatrices of the waves of the corrugated board of the base. One of the functions of the base 13 is to prevent punctures caused by syringes inserted into the cartridge. It is not necessary for said cardboard to be reinforced.
En la figura 6 puede observarse un ejemplo de cartucho según la presente invención, una vez llenado y esterilizado en autoclave. Se puede observar como la retracción de la lámina retráctil 2 ha provocado la compactación de la totalidad del cartucho. Debido a que la conexión entre la base 13 y la pared lateral del cuerpo 1 no se produce a lo largo de todo el perímetro de la base 13, la base 13 puede doblarse de manera diferente al resto del cuerpo 1 y puede alejarse de éste. El alejamiento de la base contribuye a que los residuos (por ejemplo, jeringuillas) se dispongan a lo largo de una longitud mayor y, por tanto, disminuya el área transversal que ocupan, permitiendo al cartucho reducir aún más su diámetro. Figure 6 shows an example of a cartridge according to the present invention, once filled and sterilized in an autoclave. It can be seen how the retraction of the shrink sheet 2 has caused the entire cartridge to be compacted. Because the connection between the base 13 and the side wall of the body 1 does not occur along the entire perimeter of the base 13, the base 13 can bend differently from the rest of the body 1 and can move away from it. Moving away from the base contributes to the debris (eg syringes) being arranged along a greater length and thus decreasing the cross-sectional area they occupy, allowing the cartridge to further reduce its diameter.
