  • In the configuration of the present invention described below, the same components or components having the same function is commonly represented by the same reference numerals between different drawings, and the description thereof will not be repeated. For easy understanding of the present invention, the position, size, shape, range, and the like of each of the components illustrated in the drawings do not necessarily represent the actual ones. Therefore, the present invention is not necessarily limited to the position, size, shape, range, and the like illustrated in the drawings.
  • Hereinafter, the embodiments of the present invention will be described using the drawings.
    • First Embodiment
  • Fig. 1 is a perspective view illustrating a state where a test tube rack jig according to a first embodiment of the present invention is mounted on a test tube rack.
  • Fig. 1 illustrates a test tube 101 that holds a sample such as blood, a test tube rack 102 where a plurality of test tubes 101 are arranged and stored, and a test tube rack jig 1 according to the present embodiment mounted on the test tube rack 102 from a bottom surface.
  • Fig. 2 is a diagram illustrating an aspect where the test tube rack jig illustrated in Fig. 1 is mounted on the test tube rack. As illustrated in Fig. 2, to install the test tubes 101, the test tube rack 102 includes test tube accommodation portions 202 in a grid shape (for example, test tube accommodation portions for installing 50 test tubes in 5 rows × 10 columns as illustrated in the drawing). The test tubes 101 are vertically aligned and accommodated in the test tube accommodation portions 202 and stored or transported. The test tube rack 102 is set in a predetermined automatic device for examination or the like. In the present embodiment, an external shape of the test tube rack jig 1 is quadrangular, but the external shape is not limited thereto. The external shape can change depending on the automatic device where the test tube rack 102 is to be set.
  • The test tube rack 102 according to the present embodiment is provided such that the test tube accommodation portion 202 penetrates the test tube rack 102 up to the bottom surface. In the present embodiment, the test tube rack 102 is mounted on the test tube rack jig 1 by being inserted into the test tube rack jig 1 from above in an arrow direction. The test tube rack jig 1 includes a groove according to a bottom surface 203 of the test tube rack 102, and includes a connection portion 204 on which the test tube rack 102 is mountable. In the test tube rack jig 1, a test tube holding protrusion portion 201 for fixing and holding the test tube 101 is provided. As in the present embodiment, the test tube rack jig 1 can be mounted from the bottom surface of the test tube rack 102 such that the test tube rack 102 can be easily inserted and removed when the rack is unnecessary. Even when the test tube 101 is accommodated in the test tube accommodation portion 202 of the test tube rack 102, the test tube rack jig 1 can be easily inserted and removed.
  • Fig. 3 is a top view illustrating the test tube rack jig according to the present embodiment. As illustrated in Fig. 3, in the present embodiment, the test tube holding protrusion portion 201 includes protrusion portions 201a to 201d at four positions for each of accommodation portions. As a result, the test tube 101 can be stably fixed to the test tube accommodation portion 202. However, the present invention is not limited thereto as long as at least one test tube holding protrusion portion 201 is provided to include a contact surface that can stably fix the test tube 101.
  • The test tube holding protrusion portion 201 is provided for all of the test tube accommodation portions 202 disposed in a grid shape. In the present embodiment, the test tube holding protrusion portions 201 are provided corresponding to positions of the 50 test tube accommodation portion 202 in 5 rows × 10 columns provided in the test tube rack 102. However, the present invention is not limited thereto as long as the test tube holding protrusion portions 201 are provided to be disposed corresponding to the positions of the test tube accommodation portions 202 even when the test tube rack 102 as the general test tube rack 102 includes 100 test tube accommodation portions 202 in 10 rows × 10 columns, 10 test tube accommodation portions 202 in 1 row × 10 columns, or 5 test tube accommodation portions 202 in 1 row × 5 columns.
  • Next, an aspect where the test tube according to the present embodiment is installed will be described using Figs. 4 and 5.
  • Fig. 4 is a cross-sectional view illustrating a main part of an aspect where the test tube 101 is installed on the test tube rack jig 1 according to the present embodiment. Fig. 5 is a cross-sectional perspective view illustrating the main part of an aspect where the test tube 101 is installed on the test tube rack jig 1 according to the present embodiment.
  • As illustrated in Fig. 4, when the test tube 101 is inserted into the test tube accommodation portion 202 (Fig. 2), the test tube 101 is accommodated to be supported by a test tube contact surface 401a and a test tube contact surface 401b that are inner surfaces of the test tube holding protrusion portion 201 formed according to a bottom surface shape 101a of the test tube 101. In other words, each of the test tube contact surface 401a and the test tube contact surface 401b includes a first region having a cylindrical shape and a second region having a shape as a part of a spheric shape. Fig. 4 illustrates two test tube holding protrusion portions 201 as the drawing is a cross-sectional view, but as illustrated in Fig. 5, two test tube holding protrusion portions 201 on the opposite side with respect to the test tube 101 are provided with same test tube contact surfaces and are disposed to support the test tube 101. As a result, the test tube 101 can be stably fixed to the test tube accommodation portion 202. Here, it is desirable that the test tube holding protrusion portion 201 is formed of a resin-based material of resin such as polyacetal resin (POM) or ABS resin (a collective term for acrylonitrile-butadiene-styrene copolymer synthetic resins). However, the present invention is not limited thereto, and the test tube protrusion portion 201 may be formed of a metal material such as Al.
  • As described above, in the test tube rack jig 1 according to the present embodiment, the test tube holding protrusion portion 201 is provided in the test tube rack 102, and the test tube contact surface 401a and the test tube contact surface 401b are provided according to the bottom surface shape 101a of the test tube 101. By supporting the test tube 101 with the test tube contact surface 401a and the test tube contact surface 401b, the test tube 101 installed on the test tube accommodation portion 202 can be fixed and held. It is because each of the test tube contact surface 401a and the test tube contact surface 401b includes the first region having a cylindrical shape and the second region having a spheric shape, thereby having a shape in which the contact area between the test tube contact surfaces 401a and 401b and the test tube 101 increases.
  • As described above, the test tube rack jig 1 is mountable even when the test tube 101 is accommodated in the test tube rack 102 in advance. Accordingly, by mounting the test tube rack jig 1 later, even the test tube 101 obliquely inserted into the test tube accommodation portion 202 is supported by the test tube holding protrusion portion 201 in the process of mounting the test tube rack jig 1, and the attitude of the test tube 101 can be corrected to be straight.
  • Next, an aspect where the test tube is installed on a general test tube rack formed of foamed resin including a positioning portion will be described using Figs. 6A and 6B.
  • Fig. 6A is a top view illustrating the general test tube rack formed of foamed resin and including the positioning portion, and Fig. 6B is a cross-sectional perspective view illustrating the general test tube rack formed of foamed resin and including the positioning portion. As illustrated in Figs. 6A and 6B, a general test tube rack 601 commercially available and formed of foamed resin includes a positioning portion 603 and a positioning portion 604 in a test tube accommodation portion 602. The positioning portion 603 and the positioning portion 604 are provided to come into contact with a test tube to be installed such that the test tube is positioned and held at the center as much as possible. However, in such a positioning method, positioning accuracy is determined depending on hardness of foamed resin. Therefore, positioning accuracy may be low and the test tube may be obliquely accommodated. As the entire test tube rack 601 is formed of foamed resin and is very light, when the accommodated test tube is removed, pulling strength generated by frictional force between the positioning portion 603 and the positioning portion 604 may be higher than the weight of the test tube rack 601, such that the test tube may not be removed and the test tube rack 601 may be lifted as a whole.
  • Fig. 7 is a cross-sectional view illustrating the main part of an aspect where the test tube 101 is installed while the test tube rack jig 1 according to the present embodiment is mounted on the test tube rack including the positioning portion.
  • As illustrated in Fig. 7, when the test tube 101 is inserted into the test tube accommodation portion 602 of the test tube rack 601 (Figs. 6A and 6B), the test tube holding protrusion portion 201 is provided to include the test tube contact surface 401a and the test tube contact surface 401b above the positioning portion 604. As a result, the test tube 101 previously supported by the positioning portion 603 and the positioning portion 604 is supported with the positioning portion 604, the test tube contact surface 401a, and the test tube contact surface 401b. Thus, pull strength generated by frictional force with the positioning portion 604 can be reduced, and the test tube 101 can be more easily removed. The test tube holding protrusion portion 201 is formed in a shape to be inserted into a margin of the positioning portion 604 provided on the bottom surface side of the test tube rack 601, and is provided to prevent interference from occurring when the test tube rack jig 1 is mounted on the test tube rack 601. In the present embodiment, the test tube holding protrusion portions 201 at four positions are provided to be accommodated in the margin of the positioning portion 604 of the test tube rack 601, but the present invention is not limited thereto. For example, the test tube holding protrusion portion 201 may be provided to be accommodated in the margin of a center portion of the positioning portion 604 and to include a contact surface that stably fixes the test tube 101.
  • Here, a weight of the test tube rack jig 1 is fixed and adjusted by adding weight on a material or a wall surface of the test tube rack jig 1 such that the total weight of the test tube rack 601 and the test tube rack jig 1 is higher than the pull strength of the test tube 101. In other words, the weight of the test tube rack 601 on which the test tube rack jig 1 is mounted is higher than at least the pull strength of the installed test tube 101. As a result, when the test tube 101 is removed, the test tube rack 601 can be prevented from being lifted. That is, even when the test tube rack 601 is used, the test tube 101 can be smoothly inserted and removed.
  • As described above, according to the present embodiment, it is possible to provide a test tube rack jig that corrects attitudes of test tubes mounted on test tube racks having various shapes and allows the test tubes to be easily inserted and removed. For example, when the test tube is removed, the test tube rack can be prevented from being lifted.
    • Second Embodiment
  • Fig. 8 is a cross-sectional view illustrating the main part of an aspect where a test tube is installed on a test tube rack jig according to a second embodiment of the present invention. Fig. 9 is a cross-sectional perspective view illustrating the main part of an aspect where the test tube is installed on the test tube rack jig according to the second embodiment. In the present embodiment, a bottom surface shape of the test tube and a shape of the test tube contact surface as an inner surface of the test tube holding protrusion portion are different from those of the first embodiment. The same components as those of the first embodiment are represented by the same reference numerals.
  • As illustrated in Fig. 8, when a test tube 801 is inserted into the test tube accommodation portion 202 (Fig. 2), the test tube 801 is accommodated to be supported by a test tube contact surface 803a as an inner surface of a test tube holding protrusion portion 802a and a test tube contact surface 803b as an inner surface of a test tube holding protrusion portion 802b that are formed according to a bottom surface shape 801a of the test tube 801. In other words, each of the test tube contact surface 803a and the test tube contact surface 803b includes a first region having a conical shape and a second region having a shape as a part of a spheric shape. Fig. 8 illustrates the two test tube holding protrusion portions 802a and 802b as the drawing is a cross-sectional view, but as illustrated in Fig. 9, two test tube holding protrusion portions 802a and 802b on the opposite side with respect to the test tube 801 are provided with same test tube contact surfaces and are disposed to support the test tube 801. As a result, the test tube 801 can be stably fixed to the test tube accommodation portion 202. Also in the present embodiment, the test tube holding protrusion portions 802 are provided at four positions. However, at least one test tube holding protrusion portion 802 may be provided to include a contact surface that stably fixes the test tube 801.
  • As described in the present embodiment, in the test tube holding protrusion portion 802 of the test tube rack jig 1, the test tube contact surface is formed according to the bottom surface shape of the test tube to be accommodated in the test tube rack 102. As a result, test tubes having various shapes can be coped with. As described above, as the test tube rack jig 1 is easily removable from the test tube rack 102, a change in test tube can be easily coped with by changing only the test tube rack jig 1 without changing the test tube rack 102. As in the first embodiment, by mounting the test tube rack jig 1 later, even the test tube 801 obliquely inserted into the test tube accommodation portion 202 is supported by the test tube holding protrusion portion 802 in the process of mounting the test tube rack jig 1, and the attitude of the test tube 801 can be corrected to be straight.
  • As described above, according to the present embodiment, the same effects as those of the first embodiment can be exhibited.
  • The present invention is not limited to the above embodiments and includes various modification examples.
  • For example, the embodiments described above have been described in detail to easily describe the present invention, and the present invention is not necessarily to include all the configurations described above. A part of the configuration of one embodiment can be replaced with the configuration of another embodiment, and the configuration of one embodiment can be added to the configuration of another embodiment.
