Abstract: A swab for taking biological samples which has a support rod having an end portion coated with a layer of fibres is provided. Each of the fibres extends in length orthogonally to a surface of the support rod with a respective free end portion. The layer of fibres has hydrophilic properties to allow absorption of biological samples. Each of the fibres is mechanically anchored at a bottom portion thereof to a textile substrate fixed to a surface of the end portion of the support rod.

Abstract: The present invention relates to a method for the production of bodies in plastic comprising two portions hinged to each other by a single rotation pin. The method comprises the steps: a) predisposing a mold with two distinct forming chambers for the two portions; the mold comprises a third chamber for the single pin, made and positioned in such a way that the pin is formed already aligned along the hinge axis; the mold is provided with a pair of pegs axially distanced from each other to form the third chamber and sliding along the axis between a first and a second operating position; b) positioning the pegs in the first position; c) injecting plastic material inside the chambers; d) shifting the pegs from the first to the second position, bringing the pin to engage inside the seats; e) opening the mold and extracting the two assembled portions.

Abstract: The present invention relates to a container for the collection of urine over a period of 24 hours, the inner volume of which is defined by a bottom wall, a perimetral wall and a top wall. The container comprises at least a first access mouth made on the top wall or perimetral wall, and means for drawing off the urine collected in the container. These means comprise a cup body inserted inside the container to close the first access mouth. The cup body delimits a chamber for housing a vacuum vial. On the bottom of the cup body there is an aperture which places the chamber in communication with the inner volume. These drawing means further comprise means for fluidically coupling the aperture to the vacuum vial, and a tube for sucking the urine. This tube is fluidically coupled to the aperture and extending from the bottom of the cup body as far as the bottom wall of the container.

Abstract: Plastic test tube for taking blood samples, comprising a hollow tubular body and an adhesive protective film able to adhere to the tubular body. The tubular body is made of polyethylene terephthalate and has: a tubular wall which delimits a working volume and defines an outer surface; an open mouth for insertion of liquids at a first end of the wall; and a bottom for closing a second end of the wall. The adhesive protective film is able to adhere to the wall of the tubular body over at least a portion of the outer surface. The test tube is characterized in that the wall of the tubular body has a thickness in the range of 1 to 3 mm and in that the protective film is defined by a layer of polypropylene, polyethylene or copolymers thereof. The layer has a thickness in the range of between 40 and 60 ?m and is able to form a liquid barrier.

Abstract: Protected stopper for test-tubes, including a substantially cylindrically extending elastomer inner body arrangeable to close a test-tube including a sealing portion formed to be inserted inside the mouth of the test-tube and a collar piece connected above the sealing portion and projecting radially with respect to the latter to receive, in bearing contact therewith, the mouth of said test-tube. The stopper includes a substantially cylindrical cover, closed at the top and mounted to cover the inner body. An engaging mechanism for simultaneously securing the inner body to the cover and the stopper to the test-tube are included, consisting of a plurality of projections extending on the inside of the side wall of the cover, coming into contact with the outer wall of the test-tube and spaced from the closing wall of the cover to form a contact step capable of constraining the projecting collar piece of the inner body.

Abstract: Protected stopper for test-tubes, which comprises a substantially cylindrically extending elastomer inner body (3) which can be arranged so as to close a test-tube (2) and is provided with a sealing portion (4) formed so as to be inserted inside the mouth of the test-tube (2) and a collar piece (5) connected above the sealing portion and projecting radially with respect to the latter so as to receive, in bearing contact therewith, the mouth of said test-tube (2). The stopper (1) comprises moreover a substantially cylindrical cover (6) made of plastic, closed at the top and mounted so as to cover the inner body. Engaging means for simultaneously securing the inner body to the cover and the whole stopper to the test-tube (2) are envisaged.

Abstract: A slide for the microscopic examination of biological fluids, such as urine, blood, spinal fluids, designed to count particles or elements (e.g., corpuscles) present in a predetermined sample. The slide has two plates made of a transparent material, which distinguish on their inside at least one well that is filled, by capillarity, with drops of biological fluid deposited onto the slide itself. Counting chambers are formed on the bottom of at least one well. Each chamber defines a precise volume of biological fluid to be examined. The slide is characterized by the particular and innovative shape and definition of these counting chambers. In particular, the counting chambers have a bottom surface with a roughness differing from the roughness of the boundary defining or demarcating the counting chamber.

Abstract: A slide for use in microscopic examination of biological fluid is constituted by two plates of transparent material, one plate being a bottom and the other plate being a cover, the plates forming wells which are filled by capillarity with the biological fluid to be examined. A plurality of reliefs form a plurality of computation chambers in each well. The reliefs which define each computation chamber sectioned along a plane perpendicular to the bottom of the well have a shaped section along a profile assimilable to a polygon having at least one right angle.
