DESCRIPCION DESCRIPTION
La presente invención se refiere a se refiere a un dispositivo de recogida, transporte y filtración de parásitos en heces, cuya evidente finalidad es la de recoger por parte del paciente o usuario las heces para su posterior análisis. El objeto de la invención es la de llevar a cabo la recogida de una muestra de heces por parte del paciente o usuario y el posterior traslado al laboratorio en el que tiene lugar el procesamiento de los parásitos que previamente han sido filtrados en el propio dispositivo. ANTECEDENTES DE LA INVENCIÓN The present invention relates to a device for collecting, transporting and filtering parasites in feces, the obvious purpose of which is to collect the stool by the patient or user for further analysis. The object of the invention is to carry out the collection of a stool sample by the patient or user and the subsequent transfer to the laboratory in which the processing of the parasites that have previously been filtered in the device itself takes place. BACKGROUND OF THE INVENTION
Cuando es necesario analizar las heces de un paciente, se lleva a cabo la filtración de parásitos, existiendo distintos sistemas para realizar esa filtración, sistemas que normalmente están basados en dos elementos o componentes, uno constitutivo de un recipiente en el que se depositan las muestras que se pretenden analizar, y otro constitutivo de un sistema de filtración de la muestra para su procesamiento. When it is necessary to analyze the feces of a patient, the filtration of parasites is carried out, there are different systems to perform that filtration, systems that are normally based on two elements or components, one constituting a container in which the samples are deposited which are intended to be analyzed, and another constituent of a sample filtration system for processing.
El primer componente o elemento se le proporciona directamente al paciente o usuario, siendo éste el que recoge la muestra, la deposita en ese primer elemento o recipiente y la lleva al laboratorio, donde se utilizará el segundo elemento para realizar la filtración de la muestra, operación que se realiza normalmente por gravedad, para finalmente llevar a cabo una centrifugación del filtrado y obtener el sedimento a analizar. Este sistema resulta poco eficiente, en primer lugar porque están independizados los dos componentes que intervienen en el procesado o análisis de la muestra, ya que un componente del que dispone o se proporciona al paciente debe llevarlo al laboratorio, para en éste último utilizar el segundo componente, que es ajeno o independiente al primer componente, siendo necesario llevar a cabo el acoplamiento, con los inconvenientes y problemas que de ello se derivan. DESCRIPCIÓN DE LA INVENCIÓN The first component or element is provided directly to the patient or user, being the one who collects the sample, deposits it in that first element or container and takes it to the laboratory, where the second element will be used to filter the sample, operation that is normally carried out by gravity, to finally carry out a centrifugation of the filtrate and obtain the sediment to be analyzed. This system is not very efficient, in the first place because the two components that are involved in the processing or analysis of the sample are independent, since a component that is available or provided to the patient must take it to the laboratory, to use the latter in the latter component, which is foreign or independent to the first component, being necessary to carry out the coupling, with the inconveniences and problems that arise from it. DESCRIPTION OF THE INVENTION
El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, ya que constituye un sistema compacto puesto que en un solo conjunto están integrados tanto el recipiente destinado a la recogida de la muestra como el recipiente donde se realiza la centrifugación. The device that has been recommended has been designed to solve the above-mentioned problem, since it constitutes a compact system since in a single set both the container destined for the collection of the sample and the container where the centrifugation is carried out are integrated.
Más concretamente, el dispositivo de la invención comprende un tubo dotado interiormente de dos filtros y un tapón portador de una cucharilla para la toma de la muestra, de manera que en virtud de dichos dos filtros se consigue una mejor filtración de la muestra que previamente se ha homogeneizado en el interior del tubo, de manera tal que esa mejor filtración lleva consigo el conseguir un sedimento para el análisis con menos impurezas. More specifically, the device of the invention comprises a tube internally provided with two filters and a stopper carrying a spoon for taking the sample, so that under these two filters a better filtration of the sample is achieved than previously It has homogenized inside the tube, so that better filtration leads to a sediment for analysis with less impurities.
Por consiguiente, al paciente se le proporciona el conjunto compacto y no tiene más que tomar con la cucharilla la muestra de heces, situarla en el interior del tubo y llevarla al laboratorio, realizándose en el mismo conjunto la filtración, obtención de sedimento y la centrifugación, sin necesidad de elementos distintos como ocurre tradicionalmente. Es decir, mediante el dispositivo de la invención se consigue que con el tamaño de un tubo de centrifugación de medidas estándar, se proporcione un conjunto compacto de recogida, transporte y filtración de la muestra, con una doble filtración de ésta. Como es evidente, el conjunto se ve reducido en su tamaño, implicando con ello una reducción en la cantidad del medio fijativo utilizado, es decir que proporciona una importante disminución en el material residual en laboratorio, tanto en cuanto a componentes químicos, como en lo que respecta a material de plástico desechable. DESCRIPCIÓN DE LOS DIBUJOS Therefore, the patient is provided with the compact set and has only to take the stool sample with the spoon, place it inside the tube and take it to the laboratory, performing in the same set the filtration, obtaining sediment and centrifugation , without the need for different elements as traditionally occurs. That is, by means of the device of the invention it is achieved that with the size of a standard size centrifuge tube, a compact collection, transport and filtration set of the sample is provided, with a double filtration thereof. As it is evident, the set is reduced in its size, thus implying a reduction in the amount of the fixative medium used, that is to say that it provides a significant decrease in the residual material in the laboratory, both in terms of chemical components, as well as Regarding disposable plastic material.

La figura 2.- Muestra una vista en perspectiva, pero en este caso con sección longitudinal media del dispositivo representado en la figura anterior, dejando ver todos sus componentes. Figure 2.- Shows a perspective view, but in this case with a middle longitudinal section of the device represented in the previous figure, showing all its components.
REALIZACIÓN PREFERENTE DE LA INVENCIÓN PREFERRED EMBODIMENT OF THE INVENTION
Como se puede ver en las figuras referidas, el dispositivo de la invención comprende un tubo (1 ) con una pareja de filtros (2), ligeramente distanciados entre sí, y un tapón (3) portador de una cucharilla (4) mediante la que se lleva a cabo la recogida de heces por parte del usuario, introduciendo dichas heces en el interior de ese tubo (1 ), sobre el que se ha previsto el acoplamiento axial de un segundo tubo (5) en el que tiene lugar la centrifugación de la muestra o sedimento obtenido tras el paso por los filtros (2), y cuyo tubo (5) de centrifugación cuenta con un cuello (6) a través del cual se acopla sobre el extremo del comentado tubo de recogida (1 ). As can be seen in the aforementioned figures, the device of the invention comprises a tube (1) with a pair of filters (2), slightly spaced from each other, and a stopper (3) carrying a teaspoon (4) by means of which the collection of feces by the user is carried out, introducing said feces into that tube (1), on which the axial coupling of a second tube (5) in which the centrifugation of the sample or sediment obtained after passing through the filters (2), and whose centrifuge tube (5) has a neck (6) through which it is coupled on the end of the said collection tube (1).
De esta forma se obtiene un conjunto compacto en el que se realiza no solamente la filtración de la muestra o heces, sino la centrifugación del sedimento tras el paso a través de los filtros (2), centrifugación que como se ha dicho tiene lugar en el tubo (5) acoplado sobre el tubo de recogida (1 ). In this way, a compact assembly is obtained in which not only the filtration of the sample or feces is carried out, but the centrifugation of the sediment after passing through the filters (2), centrifugation which, as said, takes place in the tube (5) coupled on the collection tube (1).
Este sistema, independientemente de las ventajas que supone en el resultado ser un conjunto compacto, se lleva a cabo un análisis con menos impurezas puesto que no existe el paso de tener que transpolar la muestra del tubo de recogida por parte del paciente al tubo donde se realiza la filtración y posterior centrifugación, ya que según la invención todos los pasos se realizan en el mismo conjunto. Además, el tamaño se ve reducido frente a los dispositivos utilizados convencionalmente, con el consiguiente ahorro tanto de material como de componentes químicos. También hay que tener en cuenta que el dispositivo de la invención resulta mucho más ecológico, al requerir menos material por ser más reducido su volumen y tamaño, respetando el medio ambiente. This system, regardless of the advantages of being a compact set in the result, an analysis with less impurities is carried out since there is no step of having to transpolate the sample from the collection tube by the patient to the tube where it is performs filtration and subsequent centrifugation, since according to the invention all steps are performed in the same set. In addition, the size is reduced compared to conventionally used devices, with the consequent saving of both material and chemical components. It must also be taken into account that the device of the invention is much more ecological, since it requires less material because its volume and size are smaller, while respecting the environment.
