Definitions

  • the present invention relates to a device for presenting containers each containing a sample of liquid to be analyzed.
  • each container containing a sample to be analyzed must be presented as quickly as possible to the analyzer.
  • This wheel the spokes of which consisted of test tubes with the plugs facing outwards, rotated so as to present each tube at a determined position, where a needle, driven in an alternating movement, carried out the sampling necessary for analysis.
  • Such a display in addition to its bulky nature, has the disadvantage of shaking the samples in an overly energetic manner, which risks destroying the blood cells by causing them to burst and thereby modifying the results of the analyzes, which may include precisely a blood count.
  • a display having the form of a rotary drum, at the periphery of which test tubes are arranged in a direction parallel to the vertical axis of revolution of the drum.
  • test tubes containing the samples to be analyzed not only promotes sedimentation but also does not cause any agitation of the liquids present in the tubes, which affects good homogenization of the sample which will be taken from each test tube and a good analysis.
  • the object of the present invention is to overcome these drawbacks.
  • the device for presenting containers, each containing a sample of liquid to be analyzed by an automatic analyzer comprises a rotary cylindrical drum, forming a hub, integral with at least two circular rings, situated in planes perpendicular to the axis of revolution of the drum and arranged at each of the ends of the drum, each of these rings having the same number of perforations or recesses, distributed along their surface and intended to receive the containers containing the samples to be analyzed, said device being characterized in that the perforations or recesses of the two end rings are arranged so that the axis of each container is inclined at an acute angle less than 45 ° relative to the axis of the drum and in this the axis of rotation of the drum is kept horizontal when the containers are presented in the automatic analyzer.
  • the axis of the drum being horizontal and rotating by a certain angle so as to successively present each container provided with a hermetic closure cap.
  • a needle driven by an alternating movement, pierces the stopper to take the sample and then transfer all or part of the contents of the container necessary for the analysis, it can be seen that the liquid to be analyzed is subjected to a double agitation, due on the one hand, to the rotation of the drum and, on the other hand, to the inclination of the axis of each container.
  • the rotary cylindrical drum of the device according to the invention may optionally comprise one or more circular rings also located in a plane perpendicular to the axis of revolution of the drum but at an intermediate level between the end rings and having the same number of perforations distributed along its surface and intended to receive the containers containing the samples by guiding them from one end to the other of the drum.
  • the receptacles containing the samples of liquid to be analyzed and arranged at the periphery of the drum in an inclined manner with respect to its axis, according to the invention, can rest on an additional circular crown of end which is neither perforated nor hollowed out and serves simply stop at the containers.
  • various means can be provided, in particular a friction retention element in the perforations or the recesses of a crown receiving the end of each container.
  • the angle of inclination between the lines connecting the centers of the perforations or recesses receiving a container and the axis of the drum is an acute angle less than 45 ° and preferably between 5 and 20 °.
  • the center of each perforation of the perforated end circular crown is aligned with the center of a perforation of the one or two intermediate rings perforated according to a generatrix of a cone having the same axis as that of the cylindrical drum so as to tilt the containers relative to this axis.
  • the external diameters of the circular rings integral with the drum then decrease from one end to the other of the drum.
  • the half-angle at the top of the cone of revolution, the generatrix of which passes through the centers of the perforations in the circular crowns, and which defines the inclination of the vessels relative to the axis of the drum is an acute angle less than 45 ° and preferably between 5 and 20 °.
  • the centers of the perforations or recesses of the end circular rings and those of the intermediate circular ring or rings are all located on the surface of a cylinder of revolution of the same axis and larger in diameter than those of the drum.
  • the centers of the perforations of the circular perforated end ring are not located on the same generatrices of this cylinder of revolution as the centers of the perforations of one or more intermediate rings, so as to present the containers inclined with respect to these generators.
  • the angle formed between the axis of the drum and the alignment of the center of a perforation of a perforated end ring with the center of the perforation of one or more perforated intermediate rings or rings closest to the generatrix of said cylinder of revolution passing through the first center, said angle defining the inclination of the containers relative to the axis of the drum, is an acute angle less than 45 ° and is preferably between 5 and 20 °.
  • the presentation device 10 as shown in any one of the attached figures, comprises a cylindrical drum 11 in the form of a central hub with axis 12.
  • This drum is integral with two circular end rings, one of which 13 is provided with perforations and the other 14 is not.
  • the drum 11 is also integral with at least one intermediate circular ring 15, located near the non-perforated end ring 14 and preferably a second intermediate circular ring 16 located near the perforated end ring.
  • Each of the intermediate circular rings 15 and 16 is provided with perforations 17 identical, in number and in size, to the perforations provided in the end crown 13.
  • These perforations 17 have a diameter sufficient to give passage to a container 18 containing the sample of liquid to be analyzed, which is generally a test tube and the perforations 17 are aligned from one crown to the other so that the assembly of these containers is placed around the drum 11.
  • Figures 1 to 3 show only the location of four containers 18 for clarity of illustration, it is obvious that, in practice, the presentation device may include a notably higher number of containers which can range up to about a hundred.
  • the centers of the perforations 17 of the perforated end ring 13 are aligned with the centers of the perforations 17 of the two intermediate rings 15 and 16 along a generatrix of a cone 19 having the same axis as the drum 11.
  • the external diameters of the different crowns can then be reduced accordingly, decreasing from that of the non-perforated end crown 14 to that of the perforated end crown 13, which facilitates reading and access to the various containers 18 containing the samples to be analyzed.
  • the half-angle at the top of the cone 19 formed by these generatrices is preferably between 5 to 15 ° approximately.
  • the generatrices of the cylinder 20 having the same axis as the drum 11 and passing through the centers 21 of the perforations 17 of the perforated end ring 13 do not coincide with the generatrices of this same cylinder 20 passing through the centers 22 of the perforations 17 of the intermediate crowns 15 and 16.
  • This angle which corresponds to the inclination of the containers 18 with respect to the axis of the drum, is preferably between 5 and 20 ° approximately.
  • the axis 12 of the drum 11 is not vertical as shown in FIGS. 1 to 3, but horizontal and the device rotates around this axis to present each of the containers 18 to the needle of the system responsible for taking the sample to be analyzed by puncturing the stopper closing the containers 18.
  • the containers 18 rotate around the axis 11 by 360 °, which causes the sample to be analyzed to be agitated.
  • each container 18 does not only move the liquid to be analyzed inside each container 18 as a result of the rotation of the drum around a horizontal axis, but, as the figures show, each container 18, as a result of its inclination relative to the axis 11 of the drum, passes successively from a downward inclined position where the liquid to be analyzed is in contact with the stopper closing the container 18 at a diametrically opposite position and inclined upward where it is less.
  • the device according to the invention is therefore particularly advantageous for analyzes of blood samples with a blood count.
  • a retention element in particular friction, which can in particular take the form of a ring 23, preferably arranged in the perforations 17 of the intermediate crown 15 closest to the non-perforated end crown 14.
  • FIG. 3 A simplified embodiment of the invention is shown in Figure 3 where the presentation device comprises only two circular rings 13 and 14 arranged at each end of a cylindrical drum 11.
  • the ring 13 is perforated as in Figure 1 but comprises in each of its perforations 17 a friction retention element 23 for retaining the containers 18.
  • the end ring 14 has as many recesses 24 intended to serve as housing at the ends of the containers 18 containing the samples to be analyzed that the crown 13 has perforations 17.
  • the centers of the recesses 24 of the crown 14 and the centers of the perforations 17 of the crown 15 are located on the surface of a cylinder 20 having the same axis as the drum 11 and a larger diameter corresponding to the spacing of these centers from the axis 13 of the drum, but these centers are offset so that the containers 18 are inclined relative to the axis of the drum at an acute angle, in particular between 5 and 20 °.
