Definitions

  • the present patent relates to caps for test tubes and containers in general for analysis laboratories and in particular concerns a new external cap for repeated closing of preliminary sample taking vacuum test tubes.
  • Preliminary sample taking test tubes are known, commonly used in numerous environments for the collection of samples of any type for analysis, for example in a medical-hospital, pharmaceutical or chemical context or in analysis laboratories in general.
  • Said sample taking test tubes comprise a glass or plastic tube with closed bottom and opposite upper end having an inlet for introduction of the sample.
  • caps are used for closing said preliminary test tubes, said caps being of the type that can be pierced with ordinary injection needles to fill the test tube with the sample.
  • Piercable caps for vacuum test tubes of the so-called external type consisting substantially of two parts: a substantially cylindrical external part open at both ends, suitable for containing the inlet of the test tube and suitable for being connected to the inlet itself, for example by screw-tightening or pressing in, and an internal part which closes and seals said inlet; said internal part is made of rubber and can be easily pierced by the needle via which the sample to be analysed is introduced into said test tube.
  • Said rubber internal part has a surface which is recessed with respect to said external part of the cap and concave towards the inside of the test tube. This prevents the user from accidentally coming into contact with any sample that may have leaked out of the test tube.
  • test tubes provided with said caps can be used in equipment and instruments for laboratory pre-analysis, archiving, etc. such as, but not limited to, the known instruments produced by companies such as Roche, Olympus, PVT, etc.
  • Said equipment and instruments comprise devices for gripping and moving said test tubes, said devices being programmed to grip closed test tubes having precisely predefined dimensions and shape.
  • test tubes and/or caps with which they are closed do not correspond to said predefined dimensions and shape, the equipment cannot grip and move said cap and/or test tube, which can therefore not be processed.
  • External caps used for repeatedly closing preliminary sample taking vacuum test tubes are known, in which said external caps for repeated closing comprise one single substantially cylindrically shaped body, suitable for containing the inlet of the test tube, open at one end for insertion of the test tube inlet and closed at the opposite end by a circular wall which is flat or even slightly convex towards the outside.
  • Said external caps for repeated closing are generally also provided with easy opening, for example tabs protruding radially from the cylindrical wall and used for gripping and removal of the cap by the user.
  • Said caps for repeated closing do not have standardised shape and dimensions with respect to the at least external shape and dimensions of said piercable external caps of the known type, and therefore the test tubes provided with said caps cannot be inserted and processed in the known preanalytical or archiving equipment and instruments, which are sized according to the known piercable external caps, for example of the widely used Vacutainer type.
  • the main aim of the present invention consists in the fact that it can be used on test tubes of the standard type so that they can be correctly processed in standard laboratory pre-analysis and/or archiving and/or analytical re-run equipment and instruments.
  • Said caps have external dimensions and shape substantially corresponding to those of the known piercable external caps, for example of the Vacutainer type.
  • the new external cap for repeated closing can have a diameter of 16 mm or a diameter of 13 mm or other dimensions compatible with sample taking test tubes of the known type, which can therefore be gripped and moved in the most common and widespread types of equipment and instruments.
  • the new cap is therefore compatible with said equipment and instruments and each test tube closed with said new cap can therefore be processed in said equipment and instruments.
  • a further advantage of the present invention is that it can be produced in any of the standard colours used for recognition of the type of sample contained and/or analysis to be performed or performed on said samples.
  • test tubes closed with said new caps can therefore also be directed along automated paths with automatic recognition of the colour of the cap.
  • the new external cap for repeated closing of vacuum test tubes comprising one single body with a substantially cylindrical lateral wall suitable for containing the inlet of the test tube, with lower end open for the insertion of said inlet and opposite upper end closed by a wall, said wall being at least partially recessed with respect to the edge of said upper end, and in which said cap has at least external shape and dimensions corresponding to the at least external shape and dimensions of the first-use piercable external caps for test tubes, for example of the Vacutainer type.
  • the new cap is preferably made in one single body, in non-toxic plastic material in compliance with the FDA standards and correlated standards, including UNI CEI ISO, UNI CEIN EN ISO, UNI EN.
  • the new cap can be produced in any of the possible standard colours commonly used to identify the contents and/or the procedures to be performed, so that the test tubes with said new caps can also be used for example in automated processes with automatic recognition of the colour of the cap.
  • Said new caps therefore effectively ensure repeated closing of the test tubes, as required by the safety standards, and furthermore allow said test tubes to be used by standard equipment and instruments, of the most common and widespread type, sized to process test tubes provided with piercable external closing caps of the standard type, for example Vacutainer.
  • Said equipment and instruments for laboratory pre-analysis, archiving etc. can for example be used in the known instruments and equipment produced by manufacturers such as Roche, Olympus, PVT, etc.
  • Figure 1 shows a section of the new cap (T), where the test tube (P) is shown by a broken line, while figure 2 shows a lateral view of the cap (T).
  • the new cap (T) for repeated closing of sample taking test tubes (P) is of the external type, i.e. comprising one single body with substantially cylindrical lateral wall (T1), suitable for externally enveloping the inlet (P1) of the test tube (P), with lower end (T2) open and upper end (T3) closed by a wall (T4).
  • Said wall (T4) is recessed with respect to the edges (T31) of said upper end and, in the preferred solution shown in figure 1 , said wall (T4) is substantially concave with a raised central part (T41), i.e. it has a profile substantially reproducing the profile of the piercable part of the known piercable external caps of the Vacutainer type.
  • Said cylindrical lateral wall (T1) and said upper closing wall (T4) therefore have at least external shape and dimensions corresponding to the shape and dimensions of said known piercable external caps of the Vacutainer type.
  • Said cylindrical lateral wall (T1) can comprise external ribs (T11) to facilitate gripping by the operator and/or by equipment and instruments, and/or internal ribs or protrusions (T12) to increase the seal of the cap (T) on the walls of the inlet (P1) of the test tube (P).
  • said cylindrical lateral wall (T1) of said new cap (T) has a diameter of 16 mm, i.e. is equal to the diameter of the known 16 mm piercable caps of the external type.
  • the new cap (T) therefore has dimensions compatible with the known test tubes (P) and with the most common and widespread equipment and instruments, such as those cited above.
  • said cylindrical lateral wall (T1) of said new cap (T) has a diameter of 13 mm, i.e. equal to the diameter of the 13 mm known piercable caps of external type.
  • the new cap (T) therefore has dimensions compatible with the known test tubes (P) and with the most common and widespread equipment and instruments, such as those cited above.
