DESCRIPCIÓN DESCRIPTION
Conjunto de apositos para reservorio subcutáneo OBJETO DE LA INVENCIÓN Set of dressings for subcutaneous reservoir OBJECT OF THE INVENTION
La presente invención pertenece al campo de la medicina, y más concretamente al campo de la limpieza y desinfección relacionadas con el uso de un reservorio subcutáneo. The present invention belongs to the field of medicine, and more specifically to the field of cleaning and disinfection related to the use of a subcutaneous reservoir.
El objeto de la presente invención es un conjunto de apositos especialmente diseñados para facilitar la limpieza y desinfección tanto de la zona de punción de un reservorio subcutáneo como de la herida provocada por la incisión realizada para introducir el reservorio. The object of the present invention is a set of dressings specially designed to facilitate cleaning and disinfection of both the puncture zone of a subcutaneous reservoir and the wound caused by the incision made to introduce the reservoir.
ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION
Un reservorio subcutáneo es un dispositivo fundamentalmente compuesto por una cámara metálica dotada de un tapón de silicona y que está conectada a través de un catéter a una vena de calibre grueso. Este dispositivo se implanta bajo la piel, permitiendo así extraer muestras y administrar fármacos y sin necesidad de pinchar repetidamente las venas del paciente. A este respecto, son conocidas en este campo los inconvenientes derivados de la punción repetida de venas. A modo de ejemplo, se puede mencionar el deterioro de las venas y el dolor para el paciente. Utilizando un reservorio subcutáneo, basta con pinchar la piel del paciente y el tapón de silicona para acceder al reservorio que, a través del catéter, está en contacto con las vías sanguíneas del paciente. A subcutaneous reservoir is a device primarily composed of a metal chamber equipped with a silicone plug and connected through a catheter to a thick gauge vein. This device is implanted under the skin, allowing samples to be extracted and drugs to be administered and without the need to repeatedly puncture the patient's veins. In this regard, the drawbacks arising from repeated puncture of veins are known in this field. As an example, the deterioration of the veins and pain for the patient can be mentioned. Using a subcutaneous reservoir, simply prick the patient's skin and the silicone plug to access the reservoir that, through the catheter, is in contact with the patient's bloodways.
Existen fundamentalmente dos tipos de tratamientos que se llevan a cabo con ayuda de un reservorio subcutáneo. Un primer tipo de tratamiento consiste en realizar administraciones periódicas de hasta 3 o 4 veces por semana, en cuyo caso el paciente es citado en el hospital en cuestión para que el facultativo realice la punción, la administración del fármaco y la posterior limpieza de la zona de punción a través de la cual se accede reservorio. Esta zona, que está ubicada sobre el lugar donde está implantado el reservorio, se mantiene normalmente cubierta por un aposito
convencional. Este aposito debe despegarse cada vez que se realiza la administración del fármaco, lo que puede ser doloroso para el paciente. There are essentially two types of treatments that are carried out with the help of a subcutaneous reservoir. A first type of treatment consists of performing periodic administrations up to 3 or 4 times per week, in which case the patient is summoned in the hospital in question so that the physician performs the puncture, the administration of the drug and the subsequent cleaning of the area of puncture through which reservoir is accessed. This area, which is located above the place where the reservoir is implanted, is normally covered by a dressing conventional. This dressing should take off every time the drug is administered, which can be painful for the patient.
Un segundo tipo de tratamiento consiste en realizar administraciones durante períodos de tiempo más largos o frecuentes, en cuyo caso se proporciona al paciente una pequeña bomba de perfusión para que lleve a cabo la administración del fármaco en su propia casa. En este segundo caso, debido a la elevada periodicidad del tratamiento, la aguja y catéter externo a los cuales se conecta la bomba de perfusión para la administración del fármaco permanecen conectados al reservorio entre una administración y otra. Actualmente, para protegerlos de posibles infecciones se utiliza únicamente una gasa y un aposito. A second type of treatment consists in administering administrations for longer or more frequent periods of time, in which case a small infusion pump is provided to the patient to carry out the administration of the drug in his own home. In this second case, due to the high periodicity of the treatment, the needle and external catheter to which the infusion pump is connected for drug administration remain connected to the reservoir between one administration and another. Currently, only gauze and a dressing are used to protect them from possible infections.
Además, en cualquiera de estos casos existe una primera etapa en la que no sólo es necesario limpiar la zona de punción del reservorio sino también la incisión, ya cerrada mediante algunos puntos de sutura, a través de la cual se introdujo inicialmente el reservorio bajo la piel del paciente. Esta pequeña incisión suele ser alargada y estar situada junto al lugar donde se encuentra el reservorio. Para mantener limpia esta incisión, actualmente se puede utilizar un aposito convencional, lo que presenta el inconveniente de que puede superponerse con el aposito que protege la zona de la punción, o bien un único aposito más grande que cubra tanto la zona de la punción como la zona de la incisión. En cualquiera de los casos, se mantiene el inconveniente relacionado con la incomodidad para el paciente que supone poner y quitar repetidamente dicho aposito. DESCRIPCIÓN DE LA INVENCIÓN In addition, in any of these cases there is a first stage in which it is not only necessary to clean the puncture area of the reservoir but also the incision, already closed by some stitches, through which the reservoir was initially introduced under the patient's skin This small incision is usually elongated and is located next to the place where the reservoir is located. To keep this incision clean, a conventional dressing can now be used, which has the disadvantage that it can overlap with the dressing that protects the puncture area, or a single larger dressing that covers both the puncture area and the area of the incision. In any of the cases, the inconvenience related to the discomfort for the patient that involves putting and removing said dressing repeatedly remains. DESCRIPTION OF THE INVENTION
La presente invención resuelve los problemas anteriores gracias a un conjunto de apositos especialmente diseñados a tal efecto. De acuerdo con la invención, este conjunto de apositos comprende fundamentalmente un primer aposito y un segundo aposito, además de un tercer aposito opcional. Estos elementos se describen a continuación: a) Primer aposito El primer aposito está diseñado para una primera fase de los cuidados en la que la
incisión a través de la cual se ha introducido el reservorio aún no ha cicatrizado. En esta fase, por tanto, es necesario llevar a cabo tareas de limpieza tanto en dicha incisión como en la zona de punción del reservorio. Por tanto, este primer aposito comprende: The present invention solves the above problems thanks to a set of specially designed dressings for this purpose. In accordance with the invention, this set of dressings essentially comprises a first and a second dressing, in addition to an optional third dressing. These elements are described below: a) First dressing The first dressing is designed for a first phase of care in which the The incision through which the reservoir has been introduced has not yet healed. In this phase, therefore, it is necessary to carry out cleaning tasks both in said incision and in the puncture area of the reservoir. Therefore, this first dressing includes:
- una base cuya superficie inferior tiene unos bordes adhesivos para fijarse a la piel de un paciente y que además tiene un primer orificio para la zona de punción del reservorio subcutáneo y un segundo orificio para la incisión realizada durante la implantación del reservorio. Preferentemente, el primer orificio es esencialmente circular y el segundo orificio es esencialmente alargado. Además, en otra realización preferida el segundo orificio está situado junto al primer orificio según una orientación esencialmente tangencial con relación al mismo. - a base whose lower surface has adhesive edges to be fixed to the skin of a patient and which also has a first hole for the puncture area of the subcutaneous reservoir and a second hole for the incision made during implantation of the reservoir. Preferably, the first hole is essentially circular and the second hole is essentially elongated. In addition, in another preferred embodiment the second hole is located next to the first hole in an essentially tangential orientation relative to it.
- una capa de cierre adecuada para pegarse a la base de manera que cubre el primer y segundo orificios. b) Segundo aposito - a closure layer suitable for sticking to the base so as to cover the first and second holes. b) Second bet
El segundo aposito está diseñado para una segunda fase en la que la incisión ya ha cicatrizado, de modo que sólo son necesarios cuidados en la zona de punción del reservorio. Por tanto, este segundo aposito comprende: The second dressing is designed for a second phase in which the incision has already healed, so that only care is needed in the puncture area of the reservoir. Therefore, this second dressing includes:
- una base cuya superficie inferior tiene unos bordes adhesivos para fijarse a la piel de un paciente y que además tiene un tercer orificio para la zona de punción del reservorio subcutáneo. - a base whose lower surface has adhesive edges to be fixed to the skin of a patient and which also has a third hole for the puncture area of the subcutaneous reservoir.
- una capa de cierre adecuada para pegarse a la base de manera que cubre el tercer orificio. c) Tercer aposito - a closure layer suitable for sticking to the base so as to cover the third hole. c) Third dress
El tercer aposito opcional está diseñado especialmente para el caso en que una administración de fármacos en modo continuo obliga a mantener una aguja y un catéter externo conectados al reservorio durante largos períodos de tiempo. Para evitar posibles infecciones, este tercer aposito comprende The third optional dressing is specially designed for the case in which a continuous administration of drugs forces to keep a needle and an external catheter connected to the reservoir for long periods of time. To avoid possible infections, this third dressing includes
- una base cuya superficie inferior tiene unos bordes adhesivos para fijarse a la piel de un paciente y que además tiene un cuarto orificio para la zona de punción del reservorio subcutáneo.
- una bolsa impermeable fijada a los bordes del cuarto orificio y dotada de una abertura para alojar una aguja y un catéter que sobresalen del reservorio subcutáneo. El modo de uso de este conjunto de apositos sería el siguiente. Una vez implantado el reservorio subcutáneo, se pega la base del primer aposito sobre la piel del paciente de modo que la zona donde se realizará la punción del reservorio subcutáneo queda accesible a través del primer orificio y la herida correspondiente a la incisión realizada para introducir dicho reservorio queda también accesible a través del segundo orificio. Los bordes adhesivos del primer aposito preferentemente serán lo suficientemente firmes como para que se mantenga fijado a la piel del paciente durante varios días. A continuación, se pega la capa de cierre del primer aposito sobre la base. - a base whose lower surface has adhesive edges to be fixed to the skin of a patient and which also has a fourth hole for the puncture area of the subcutaneous reservoir. - a waterproof bag fixed to the edges of the fourth hole and provided with an opening to accommodate a needle and a catheter protruding from the subcutaneous reservoir. The mode of use of this set of bets would be as follows. Once the subcutaneous reservoir is implanted, the base of the first dressing is glued on the patient's skin so that the area where the subcutaneous reservoir is punctured is accessible through the first hole and the wound corresponding to the incision made to introduce said reservoir is also accessible through the second hole. The adhesive edges of the first dressing will preferably be firm enough to remain fixed to the patient's skin for several days. Next, the closure layer of the first dressing is glued on the base.
Esta configuración permite al personal sanitario acceder tanto a la zona de punción del reservorio como a la zona de la incisión. Se pueden realizar así cómodamente tanto la administración de fármacos como la limpieza de ambas zonas. Tras cada operación de limpieza, se fija a la base una capa de cierre que protege ambas zonas hasta la siguiente operación. Otra ventaja de esta configuración es que, al pegarse y despegarse la capa de cierre sobre la base y no sobre la piel del paciente, se evitan daños al paciente. Además, la capa de cierre puede ser transparente para permitir la visualización del estado de la zona de punción del reservorio o de la incisión. This configuration allows health personnel to access both the puncture area of the reservoir and the area of the incision. Thus, both drug administration and cleaning of both areas can be comfortably performed. After each cleaning operation, a closure layer is attached to the base that protects both zones until the next operation. Another advantage of this configuration is that, by sticking and peeling off the closure layer on the base and not on the patient's skin, damage to the patient is avoided. In addition, the closure layer may be transparent to allow visualization of the state of the puncture zone of the reservoir or of the incision.
En una fase posterior, una vez que la incisión realizada para introducir el reservorio subcutáneo ha cicatrizado completamente, se pasa a utilizar el segundo aposito. Se fija la base de este segundo aposito de manera que la zona donde se realiza la punción del reservorio subcutáneo queda accesible a través del tercer orificio. A continuación, se tapa éste utilizando la correspondiente capa de cierre. Excepto en lo que respecta al número, forma y posición de los orificios, el resto de características del segundo aposito son similares a las descritas para el primer aposito. El tercer aposito se utilizaría sólo en caso de que se vaya a realizar la administración continua de fármacos en el domicilio del paciente, lo que implicaría que una aguja y un catéter externo de conexión con una bomba de perfusión permaneciesen conectados al reservorio subcutáneo durante largos períodos de tiempo. La base del tercer aposito se pega sobre la piel del paciente de modo que la zona de punción del reservorio subcutáneo quede accesible a través del cuarto orificio. La aguja y catéter conectados
al reservorio subcutáneo y que sobresalen de la piel del paciente quedan así alojados dentro de la bolsa impermeable. Ésta, además, está abierta por un extremo opuesto al lugar de la conexión al cuarto orificio, pero tiene un cierre que permite abrir y cerrar la bolsa según se requiera. At a later stage, once the incision made to introduce the subcutaneous reservoir has completely healed, the second dressing is used. The base of this second dressing is fixed so that the area where the subcutaneous reservoir is punctured is accessible through the third hole. This is then covered using the corresponding closure layer. Except for the number, shape and position of the holes, the rest of the characteristics of the second dressing are similar to those described for the first dressing. The third dressing would be used only in case of continuous administration of drugs at the patient's home, which would imply that a needle and an external catheter connected to an infusion pump remained connected to the subcutaneous reservoir for long periods. of time. The base of the third dressing is glued on the patient's skin so that the puncture area of the subcutaneous reservoir is accessible through the fourth hole. The connected needle and catheter to the subcutaneous reservoir and protruding from the patient's skin are thus housed inside the waterproof bag. This, moreover, is open at an end opposite the place of connection to the fourth hole, but has a closure that allows the bag to be opened and closed as required.

REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
La Fig. 1 muestra un reservorio subcutáneo (100) convencional. Como se puede apreciar, el reservorio (100) está formado por una cámara (101) y un catéter (102) que se conecta a la vena en cuestión. La cámara (101) tiene además una zona (103) de silicona a la que se puede acceder repetidas veces pinchando con una aguja a través de la piel del paciente. La Fig. 2 muestra el aspecto que tiene el reservorio subcutáneo (100) ya implantado en un paciente. Como se puede apreciar, el reservorio (100) genera una pequeña protuberancia junto a la cual queda la cicatriz (104) correspondiente a la incisión a través de la cual se introdujo. Normalmente, la posición relativa de reservorio (100) e incisión o cicatriz (104) es similar a la mostrada en esta figura: la incisión (104) está ligeramente separada del reservorio (100) y orientada según una dirección esencialmente tangencial con relación al mismo. Fig. 1 shows a conventional subcutaneous reservoir (100). As can be seen, the reservoir (100) is formed by a chamber (101) and a catheter (102) that connects to the vein in question. The chamber (101) also has a silicone area (103) which can be accessed repeatedly by pricking with a needle through the patient's skin. Fig. 2 shows what the subcutaneous reservoir (100) already implanted in a patient looks like. As can be seen, the reservoir (100) generates a small protuberance next to which the scar (104) corresponding to the incision through which it was introduced remains. Normally, the relative position of the reservoir (100) and incision or scar (104) is similar to that shown in this figure: the incision (104) is slightly separated from the reservoir (100) and oriented in an essentially tangential direction relative to it .
Las Figs. 3 y 4 muestran los dos apositos (1 , 2) que constituyen el conjunto de la invención. El primer aposito (1) está formado por una base (11) de forma esencialmente rectangular que está dotada de dos orificios: un primer orificio (12) circular que permitirá acceder a la zona del reservorio (100) implantado en el paciente, y un segundo orificio (13) rectangular que permitirá acceder a la herida
correspondiente a la incisión (104). Como se puede apreciar por comparación con la Fig. 2, las posiciones relativas del primer y segundo orificios (12, 13) se corresponden con las del reservorio (100) y la incisión (104). Así, una vez la base (11) se ha adherido firmemente a la piel del paciente, el personal médico o el propio paciente pueden acceder tanto a la zona de punción del reservorio (100) como a la incisión (104). Figs. 3 and 4 show the two dressings (1, 2) that constitute the whole of the invention. The first dressing (1) is formed by an essentially rectangular base (11) that is provided with two holes: a first circular hole (12) that will allow access to the area of the reservoir (100) implanted in the patient, and a second rectangular hole (13) that will allow access to the wound corresponding to the incision (104). As can be seen by comparison with Fig. 2, the relative positions of the first and second holes (12, 13) correspond to those of the reservoir (100) and the incision (104). Thus, once the base (11) has firmly adhered to the patient's skin, the medical staff or the patient can access both the puncture area of the reservoir (100) and the incision (104).
El primer aposito (1) comprende además una capa (14) de cierre que se fija sobre la base (11) para tapar la zona de punción del reservorio (100) y la incisión (104) y evitar agresiones externas. Además, esta capa (14) de cierre puede ser transparente en la zona de punción del reservorio (100) y/o en la zona de incisión (104). Esto permite comprobar el estado de ambas sin necesidad de despegar la capa (14) de cierre. The first dressing (1) further comprises a closing layer (14) that is fixed on the base (11) to cover the puncture zone of the reservoir (100) and the incision (104) and avoid external aggressions. In addition, this closure layer (14) can be transparent in the puncture zone of the reservoir (100) and / or in the incision zone (104). This allows the status of both to be checked without the need to peel the closure layer (14).
El segundo aposito (2) está formado por una base (21) también de forma esencialmente rectangular pero que en este caso está dotada únicamente de un tercer orificio (22) diseñado para acceder a la zona de punción del reservorio (100). Este segundo aposito (2) sustituye al primero una vez la incisión (104) ha cicatrizado completamente. La zona de punción del reservorio (100) se cubre por medio de una capa (24) de cierre similar a la utilizada con el primer aposito (1). Esta capa (24) de cierre también puede ser transparente en la zona de punción del reservorio (100). The second dressing (2) is formed by a base (21) also essentially rectangular in shape but which in this case is provided only with a third hole (22) designed to access the puncture zone of the reservoir (100). This second dressing (2) replaces the first once the incision (104) has completely healed. The puncture zone of the reservoir (100) is covered by means of a closing layer (24) similar to that used with the first dressing (1). This closure layer (24) can also be transparent in the puncture zone of the reservoir (100).
La Fig. 5 muestra un tercer aposito (3) que se utiliza sólo en caso de que se vaya a realizar una administración de fármacos continua que requiera mantener una aguja y un catéter externo conectados al reservorio (100) durante largos períodos de tiempo. El tercer aposito (3) está formado por una base (31) que se pega a la piel del paciente y que está dotada de un cuarto orificio (32) que se hace coincidir con la zona de punción del reservorio (100). Además, este tercer aposito (3) tiene una bolsa (35) que está conectada a los bordes del cuarto orificio (32) de manera que la aguja y el catéter externo quedan alojados dentro de la bolsa (35) cuando la base (31) está fijada al paciente. La bolsa (25) tiene una abertura (36) situada en el lado opuesto al del cuarto orificio (32) que permite extraer el catéter externo para conectarlo a la bomba de perfusión. Además, cuando no se está utilizando la bomba, un medio de cierre (no mostrado en las figuras) esencialmente hermético permite cerrar la abertura (36) para evitar posibles infecciones.
Fig. 5 shows a third dressing (3) that is used only in case of continuous administration of drugs that requires keeping a needle and an external catheter connected to the reservoir (100) for long periods of time. The third dressing (3) is formed by a base (31) that sticks to the patient's skin and is provided with a fourth hole (32) that is made to coincide with the puncture zone of the reservoir (100). In addition, this third dressing (3) has a bag (35) that is connected to the edges of the fourth hole (32) so that the needle and the external catheter are housed inside the bag (35) when the base (31) It is fixed to the patient. The bag (25) has an opening (36) located on the opposite side of the fourth hole (32) that allows the external catheter to be removed for connection to the infusion pump. In addition, when the pump is not being used, an essentially hermetic closing means (not shown in the figures) allows closing the opening (36) to avoid possible infections.
