DISCRIPTIVE REPORT OF UTILITY MODEL "CONSTRUCTIVE IMPROVEMENT INTRODUCED TO RECIPIENT DESTINED TO COLECTING, KEEPING, TRANSPORTING, DELUTING AND FILTRATION OF LEES SAMPLE FOR MEANS OF PARASITOLOGICAL EXAMINATION." The present request of patent of utility model is about a new "CONSTRUCTIVE IMPROVEMENT INTRODUCED IN RECIPIENT DESTINED TO COLECTING, KEEPING, TRANSPORTING, DELUTING AND FILTRATING LEES SAMPLE FOR MEANS OF PARASITOLOGICAL EXAMINATION" in which the petitioner presents an unpublished proposal, notably for the constructive concept of the filter element for the refined separation of the collected less material whose application is focused in clinical analysis lab use. By the new constructive concept, all professionals of the clinical analysis will be able to use an extremely useful tool in terms of obtaining filtered lees material, which presents incomparable reading quality, once the filtration process here petitioned allows an extremely selective separation of the elements that really interest in the process of clinical analysis. Besides providing the listed gains of quality in relation to the material subject to clinical analysis, the evolutive constructive concept brings in its bosom a geometric condition to the filtering element, in a cylindrical shape, providing a bigger filtering area, optimizing then the obtaining of the proper material to be analyzed. Still under the scope of the gained advantages, it is also possible to realize a quantitative reduction on the recipient size, leading to a manufacturing cost reduction, besides using an encasement system between the cover and the recipient that results in a trustful closing, preventing possible leaking. Because of all these aspects the petitioner understands that such solution represents an evolution in relation to the solutions known by the technician state. It is known by the technician state that the manufacturing companies of equipments and accessories for the clinical analysis practice, specially those who take to the production and commercialization of lees collector recipients for the parasitologic analysis have noticed a huge technological development in the past decades, when gadgets were introduced whose technology promotes the formation of the material to be analyzed, which has, in its composition, the elements subject to this analysis To reach such performance, the collection conservation, transportation, dilution and filtering recipients of lees samples, are provided with filtering elements in their interior, characterized, in the majority, by a filter of conical format which is composed by high density polietilenun canvas, whose holes are weaved with an average of 500 micra separation. This condition can be considered acceptable, although it is far from being the best condition of filtering to be obtained. One of the possible reasons that lead to this stationary condition in terms of the efficiency of the filtering of the resulting material to be analyzed, certainly stands in the technological unavailability, when it was created, in obtaining a filtering weaving which is more precise than the one recognized in the state of technique. Another reason that may interfere in the performance of the elements of the collection, conservation, transportation, dilution and filtering recipients of lees samples, is the fact that, even for the manufacturing of a tissue of 500 micra, it isn't possible to trust its production process. The fact of low reliance on the lot manufactured of this kind of recipient can be explained by the analysis of the obtaining form of the filtering tissue, which is based on the insertion of high density polietilenum, that contains holes that present variation not only in the distance as well as in the quantity, once during the injection process it is frequent the non perforation of an entire area, because of the necessity of the use of tools of injection pattern in which it is mandatory the use of gadgets called 'fakes' in which the perforation of the tissue is effectively formed. The condition listed above requires 'fake' elements with a series of points to generate a distance of approximately 500 micra each, very thin, so that it can guarantee its integrity during the repetitive process of material injection, risking then the performance of the filtrating element.

Finally, one last aspect left to be considered is the one referring to the bio-safety, envolved in any activity of clinical analysis, once the handling of infectious material is considered of high risk, allowing the professional that is handling the material to be infected due to possible accidents in the lab. The colecting recipients known in the technician state, ask for the use of gadgets, centrifuge like, so that a homogenisation of the filtered material can be obtained, because this condiction can't be obtained naturally due to the variation observed on the tissue making of 500 micras, and being the centrifuge gadget a determining agent in causing accidents risk, causes the recipients commercialized and used currently not to stand up to the requirements of the concept of bio safety. Still concerning the concept of bio safety, such recipients allow an alternative method for homogenisation of the filtered material, which consists on the process of spontaneous sedimentation, that on the other hand, for requesting more time for obtaining the homogeneous sample, is impossible, from the operational point of view in a working schedule of a lab of clinical analysis, having then a prohibitive cost. Once we know the limitations of the products for collection, conservation, transportation, dilution and filtering recipients of lees samples, explained above, the petitioner claims in his solution a constructive concept in which it is possible to realize a filtration of the material to be analyzed, extremely efficient, adding a new and never seen condition of reliability of the product, which could never be experienced by any other similar product known in the technician state so far. To complete the present description of the way of obtaining the best comprehension of the characteristics of the present request of utility model, attached to this description is a set of pictures, that in a explanatory way, although not limitated, was represented one form of the requested recipient where: Picture 1 is a lateral view of the requested recipient duly assembled. Picture 2 is a superior view of the requested recipient duly assembled. Picture 3 is an inferior view of the requested recipient duly assembled. Picture 4 is a representation of the lateral view of the component parts of the requested recipient. Picture 5 is a representation of the lateral view of the filtering system of the requested recipient. Picture 6 is a representation of the plan view of the filtering system of the requested recipient. Picture 7 is a representation of an inferior view of the filtering system of the requested recipient Detail 1 is a representation of a zoomed cut of the filtering system of the requested recipient. Picture 8 is a representation of a cut of the requested recipient duly assembled. Refering to the pictures the present petition of patent of utility model refers to a new "CONSTRUCTIVE IMPROVEMENT INTRODUCED TO RECIPIENT DESTINED TO COLLECTING, KEEPING, TRANSPORTING, DELUTING AND FILTRATING LEES SAMPLE FOR MEANS OF PARASITOLOGICAL EXAMINATION", where in the pictures 1 , 2 and 3 we have the representation in lateral, plant and inferior view of the recipient element assembled (A), which is characterized externally by the attaching of the covering element (C) together with the bottle element (B), where the extreme portion of the covering element (C) receives a removable hindrance cap element (D). Picture 4, shows in details the composition of each one of these components, starting from the bottle (B)1 that is characterized by a cylindrical recipient (B1), with capacity of approximately 35 milliliters (ml), which has an internal area dedicated to the filtering element (E), along with the preservation liquid (G), being its bottom (B3), projected in form of a conic salience, in a way to optimize the attachment of the filtering element (E). The superior portion of the bottle element (B), known as "mouth", is provided with saliencies (B2), in helicoidal form, assembling then a thread of encasement of the filtering element (E). The covering element (C) is composed by a main body (C1), which contains in its interior a contrariwise thread element, duly projected to receive the thread portion (B2) of the bottle element (B), allowing then the efficient closing of the assembled recipient (A), avoiding leaking, being complemented by a sewer beak on the covering (C2). The filtering element (E), better detailed on the pictures 5, 6 and 7, presents constructive composed concept of superior mouth element (E1), of circular form, being manufactured preferably in polymeric material of the polyester kind, whose function is to allow the filling of the assembled recipient (A). The project of the filtering element (E) foresees that such configuration of the superior mouth element (E1 ), shall be in a way that allows this one a perfect adjustment of the walls inside of the covering element (C), allowing then a better stability of it when dully assembled inside the assembled recipient (A), being better viewed on the pictures 5, 6 and 8. The lateral portion of the filtering element (E) is defined by a structure tissue of polyester (E2), in cylindrical format, whose composition is defined equally to the same polymeric material of the polyester kind, where its main function is providing, with the highest efficiency, the filtration of the material really necessary to the parasitological analysis, which means that such tissue allows the obtained substrate to be rich in parasites, considering that other elements that make part of the lees, and beyond interest of the listed analysis, are retained in the filter. The petitioner emphasizes that such efficiency during the filtration comes from the fact that the texture of the polyester tissue element (E2), presents itself in holes of distance that can be specified, during its fabrication, between 150 to 350 micra, being such conformation better viewed by the representation created in the detail 1. Still under the scope of the analysis of the gained advantages because of the innovation of the referred filter, the petitioner emphasizes that the technology used for obtaining it is extremely reliable, so that there will not be the possibility of occurring areas with ill conformation in perforation and therefore the manufacturer of the product can finally offer to the market a product with the quality certification, because the lots of fabrication of the recipient will always offer the same efficiency and reliability. From the inferior portion of the polyester tissue structure (E2) an element called staff (E3) is born, in whose inferior portion is born the collector element (E4), formed preferably in shell format, that presents in its utility area, elements of groove or hole kind (E4), projected with the capability to retain aproximately 1 gram of lees sample for analysis. The portion of the bottom of the collector element (E5) is projected so that it attaches perfectly to the bottom (B3) of the bottle element (B3), guaranteeing one more perfect assembling of the collector element (E4) in the interior of the assembled recipient (A), being better observed on the pictures 5, 7 and 8. The picture 8 is a view in a longitudinal cut of the assembled recipient (A), from which it is possible to comprehend the way of work of its functional concept, where the material subject to parasitological analysis, called leed, is placed inside the assembled recipient (A)1 more specifically inside the filtering element (E), being this one covered and closed by the attachment of the covering element (C) to the mouth (B2) of the element bottle (B), and still the the empty beak of the covering (C2) is covered by a cap element of closing (D). The filtering element (E) starts to act in a way that the filtered material (F) subject of the parasitological analysis, passes through the element polyester tissue (E2), according to the ilustration in the detail 1. The filtered material (F), also because of gravity, is taken to the collector element (5), getting to the holes and grooves (E5), that shall retain close to 1 gram of the filtered material to be analysed. It is important to emphasize that the filtered material to be analysed is under a preserving liquid (G), avoiding its degenaration. The petitioner emphasizes that by making it possible to produce in large scale series of assembled recipients (A), where there begins to be qualitative warranties in obtaining the filtered material for the parasitological analysis, it becomes possible to eliminate the use of every and each kind of gadget and/or methods for obtaining a homogeneous sample. Such assertion is true as, thanks to the filtering with the polyester tissue element (E2), the resultant filtered material is found next to the homoqenization condition, requirinq a simple shaking of the assembled recipient (A), for a better mix of the filtered material (F) with the preserving liquid (G), being such mix expelled by the beak of the covering (C2), poured directly on the lamina for a microscope analysis, being such procedure done in reduced time, besides giving to the requested assembled recipient (A) a high classification in the concept of bio-safety.
