Definitions

  • the present invention relates to a rack for holding a plurality of tubes, and more particularly, concerns an improvement in a multiple tube rack for holding test tubes and the like during laboratory or clinical procedures.
  • test tubes or vials during laboratory or clinical procedures, the user may require many test tubes at one time. For example, a plurality of test tubes are needed for various assay procedures. As the number of test tubes and implements which the user is relying on increases, it is sometimes awkward or difficult for the user to use two hands in handling different items. Such difficulty might arise when using standard metal test _tube frames. These standard frames generally have two holes for each test tube, a hole through an upper framework and another hole through a lower framework aligned therewith. If the user needs to remove a plug or cap in the test tubes held in a standard metal frame, two hands are normally required, one to hold the test tube in place and the other to remove the cap.
  • test tubes are closely arranged, using two hands for these procedures can be awkward while also increasing the risk that tubes or frames may be knocked over.
  • two hands anytime two hands are used, the possibility of cross contamination between tubes may be increased since more items may be touched with two hands.
  • test tubes or vials It is therefore desirable for a user of test tubes or vials to be able to use one hand to work with test tubes which are closed and which require the removal of caps or plugs to gain access to the interior of the tubes. Furthermore, a compact work station would also assist the user of a plurality of test tubes during laboratory or clinical procedures. It is toward the satisfaction of these desires and aims which the present invention is directed.
  • the rack of the present invention holds a plurality of tubes.
  • This rack comprises a support member having a plurality of holes therein for receiving tubes. Each hole has a substantially flat wall portion surrounding same to prevent rotation of a tube placed therein.
  • the support member is substantially planar and has a raised upper surface and an annular flange therearound to facilitate fastening the rack to a work surface.
  • the support member has a plurality of wells therein depending from the raised upper surface. These wells are preferably arranged in orthogonal rows and columns in the support member. Each well preferably has two substantially flat, planar sidewalls opposed from each other, two curved, concave sidewalls opposed from each other and a closed concavely curved bottom.
  • a tube rack assembly in another aspect of the present invention, includes a rack substantially as described above.
  • a tube is in one of the holes in the support member of the rack.
  • This tube has a closed end portion and at least one substantially flat wall surface in face-to-face alignment with the flat wall portion so that rotation of the tube in the hole is prevented.
  • the present invention allows the tubes to be placed in the tube rack assembly and a cap or plug therefor to be removed and replaced with only one hand.
  • the fit between tubes and wells of the present tube rack assembly can be designed so that the tubes fit snuggly and will not drop out of the assembly even if the assembly is turned over.
  • the present tube rack may be affixed to a work surface so that the rack will not slide or be readily moved when the user is placing tubes in and out of the rack.
  • the present invention may be made of plastic materials which can be made inexpensively so as to be disposable after use.
  • Assembly 10 has a minimum number of general components a multiple tube rack 12 and at least one tube 14. Tubes 14a and 14b are illustrated in F ig. 1 to demonstrate that the size of the tubes may vary, if desired. Also, while not shown in Fig. 1, there may be as many tubes as there are wells in the rack, as part of the present invention.
  • Rack 12 consists of a-generally planar support member 16 having a raised upper surface 18. Sidewalls 19 support raised upper surface 18. There is preferably an annular flange 20 surrounding sidewalls 19 around the entire periphery of rack 12. As seen in Fig. 1, rack 12 has a substantially square configuration; it is understood that various configurations of the rack fall within the purview of the present invention. Depending from upper surface 18 is a plurality of wells 21. These wells are preferably distributed throughout the support member and arranged in orthogonal rows and columns. In the embodiment being described, each well has a curved, concave closed bottom 22. In order to prevent rotation of tubes in the wells, the wells are preferably fabricated with at least one flat wall. As can be seen in Fig.
  • the wells of the embodiment being described has two flat, planar sidewalls 24a and 24b opposed from each other; in addition, each of these wells includes two curved, concave sidewalls 25a and 25b opposed from each other.
  • the shapes and orientation of these respective walls contribute to preventing the rotation of the tube in the well. It is understood that, instead of wells with closed bottoms, holes may be formed through upper surface 18 with the two flattened and two curved wall portions surrounding the hole to prevent rotation of a tube placed therein.
  • Tube 14 preferably includes a cylindrical body 30 with a closed end 31 and an open end 32.
  • a threaded portion 34 surrounds open end 32.
  • a cap 35 is preferably threaded onto the tube to cover open end 32.
  • closed end 31 has a rounded configuration.
  • the closed end portion of the tube includes two substantially flat, planar wall surfaces 36a and 36b opposed from each other.
  • the closed end portion of the tube has two curved, concave wall surfaces 38a and 38b. These respective flat and curved wall surfaces of the tube are in face-to-face alignment with the flat and curved wall portions, respectively, of the well into which the tube is positioned. With this type of structural arrangement, rotation of the tube in the well is prevented.
  • the bottom side of flange 20 may be provided with a suitable adhesive.
  • a double-sided adhesive tape (not shown) around the bottom of the flange would allow the user to remove the cover strip and position rack 12 in a fixed position on a work surface.
  • Use of the rack of the present invention can then proceed with the assurance that movement of the rack will be prevented.
  • other fastening means may be employed to affix the rack to a work surface, particularly in conjunction with the peripheral flange.
  • Fig. 1 illustrates all wells 21 being substantially uniform in size and shape
  • the wells may have different sizes for different size tubes.
  • tube 40 has a substantially cylindrical body 41 and an end cap 42 covering the open end thereof.
  • the closed end of the tube is a flattened end 44.
  • Two substantially flat, planar wall surfaces 45 are included in the tube, similar to the embodiment described above.
  • tube 50 has a substantially cylindrical body 51 and an endcap covering an open end thereof.
  • the closed end of the tube is a flattened end 54.
  • This embodiment has four substantially flat planar wall surfaces, all designated with numeral 55.
  • tube 60 has a substantially cylindrical body 61 and an end cap 62 covering an open end thereof.
  • the closed end of this tube is a rounded end 64.
  • This embodiment also includes four substantially flat, planar wall surfaces, all designated as numeral 65. It is understood that when the tubes illustrated in Figs. 5 and 6 are employed in the rack of the present invention, the wells or holes preferably include four substantially flat, planar wall portions to mate in face-to-face alignment with the flat wall surfaces of the tube so as to prevent rotation of the tube when positioned in the rack.
  • rack 12 be made out of plastic material. Further, it is preferred that rack 12 be formed in one piece in an economical molding or stamping process.
  • the tubes of the present invention are preferably made of clear material, such as glass or plastic.
  • the fit between the tubes and the wells be tight so that a snug fit may be achieved. In this fashion, should the rack be upset or otherwise turned over, the tubes will remain in position.
  • the present invention provides a tube rack assembly in which the tubes and rack have mating, cooperating surfaces for holding the tubes in position in the rack. Rotation of the tubes is prevented so that the user of the present invention may remove and replace the cap with one hand.
  • the rack assembly may be affixed to the work surface to prevent its movement during use.
