Abstract: Needle support assembly for a venous blood collection device with evacuated vial, comprising a support body having a coupling seat for a vein needle and coupling seat for a vial needle. The support body is provided with an inner chamber having an entrance and an exit. The support body is made at least partially in transparent or semi-transparent material to permit the visualization of the blood flow. The inner chamber has a mean cross-section greater than the cross-sections of both the coupling seats and is divided into compartments communicating with each other which define one or more channels for the blood flow from the entrance to the exit. Each channel defines a path for the blood which moves away from the entrance to the exit. Each channel defines a path for the blood which moves away from the straight line connecting the entrance and the exit and has a smaller cross-section than the mean cross-section of the inner chamber.

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: A laboratory test tube is formed between male and female mold elements by injection of molten plastic material. The female element has a bottom element formed by first and second alternating complementarily shaped wedges. At least the second wedges are able to move under the pressure of the molten plastic from a rest position to an operative position in order to form slits which allow air, but not molten plastic, to exit from the mold.

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: Plastic material is injected into a chamber defined between a female mold member and a male mold member, while air is evacuated from the chamber. In the evacuation step, the air contained in the forming chamber progressively exits from the mold under the pressure of the melted plastic material through a multiplicity of slits made on the female element at different heights along the above-mentioned central axis. The slits have dimensions such as to allow the passage of the air and at the same time to block the flow of the melted plastic material from the forming chamber.

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.
