Description

  The present invention relates to a test tube used in an analytical test for medical treatment, medicine, food, and the like.

  When currently performing test / analysis using test tubes, several hundred test tubes are used as inspection objects. At this time, in order to handle and manage these numbers, it is necessary to handle them one by one. Therefore, even if a test tube stand is used, it is a very complicated operation.

  In addition, when manufacturing test tubes by resin molding, styrene resin is mainly used, but in order to sterilize after molding, ultraviolet rays, electron beams, X-rays or gamma rays are irradiated at the molding factory, and then delivered. To do. Very expensive equipment is required for electron beam, X-ray and gamma ray irradiation.

  Although there is ultraviolet irradiation as an inexpensive method, ultraviolet rays are hindered when stored in a packaging material film. If the test tubes overlap at the same time, the ultraviolet rays are similarly blocked, and it is necessary to secure the irradiation direction vertically one by one, which is a complicated operation.

  For those belonging to pathogenic bacteria such as Shigella, Salmonella typhi, Salmonella, etc., careful handling of the test tubes is required. In particular, there was a risk of touching the test tube opening, which is the only opening of the test tube, and there was a need for improvement.

  In a conventional test tube, each single unit is separated and packaged in units of 100 to 200. As preparation work for inspection, there is a work to put the test tube in the test tube stand, but since it is packed in pieces, if the test tube with irregular test tube port is not set up in the test tube stand regularly Don't be. In addition, since each test tube is lifted one by one in the test determination of each test tube, each operation is complicated and takes time. The present invention intends to solve the cost reduction due to the increase in work efficiency and the reduction in time.

  Test tubes made of styrene resin require ultraviolet irradiation and electron irradiation for sterilization. After releasing from the resin mold, they are stored in vinyl bags in units of 100 to 300. They were then sterilized by irradiation. However, electron irradiation is expensive in terms of equipment, and when it is attempted to irradiate ultraviolet rays instead, there are problems such as the film on the outer bag and the overlapping test tubes shielding the ultraviolet rays.

  In addition, when irradiating with ultraviolet rays, the positions of the test tube mouths must be maintained one by one in the irradiation direction, which is not practical.

At the same time, it is necessary to ensure that the test tubes are parallel to each other after molding, and it is necessary to prevent deformation when taking out, packing and transporting the molding machine.

  Since the conventional test tube has a simple cylindrical shape with an opening in the upper part, there is a possibility that the contents may come into contact with the opening if it is attached to the opening.

  When storing test tubes after use, it was necessary to put caps on them one by one.

  Conventional test tubes are premised on using a test tube stand. Therefore, it could not stand upright without a test tube stand.

  In the present invention, in order to solve such a problem, an outer edge is provided on the upper portion of the test tube main body.

  Further, the outer edges are connected by resin molding.

  An opening or a recess for holding the test tube is provided at a required position of the outer edge formed by coupling.

A rib having a standard thickness of 1 mm and a length of 15 mm is provided as a supporting part at the lower part of each connecting part.

  The upper surface of the connecting portion provided on the outer edge of the opening of the test tube is configured to be a flat surface, and a paste margin for pasting such as a heat welding film or an adhesive film is provided.

  A connection portion having a flat upper surface is formed around the outer periphery of the test tube port of the test tube, and the required number of the connection portions are joined together to obtain a connected test tube.

  At this time, a rib portion is provided at the lower portion of the connecting portion to support each other.

  The number of connected test tubes is preferably a triangle shape if three, and a quadrangle if four. The connected test tube of the present invention having such a shape is self-supporting without using a test tube stand.

  FIG. 1 is an embodiment showing a connected test tube of the present invention. In the drawing, the test tubes 1 are integrated with each other by a connecting portion 3 in the lateral direction.

  In FIG. 2, an opening 4 is provided at the center of each connecting portion 3. The opening 4 is handled by lifting up the test tubes connected by the holder 5 as shown in FIG.

  Similarly, in FIG. 4, the holder 5 can be inserted between the test tubes located at the lower part of the connecting portion 3 of the connected test tube 1, and the whole can be lifted.

  The connected test tubes 1 according to the present invention in FIG. 5 are connected in the vertical and horizontal directions and are self-supporting without using a test tube stand.

  In FIGS. 6 and 7, the upper part of the test tube is integrated by connecting the connecting part 3, and the upper part is configured as a plane. A heat welding film or an adhesive film 6 is stuck on the plane, and the test tube is sealed.

The sealing is performed to prevent contamination after sterilization by ultraviolet irradiation after resin molding.
It may also be done for specimen storage after a test test.

  FIG. 8 shows notches 7 and protrusions 8 for a jigsaw provided on the upper outer edge of a single test tube. The notches 7 and the protrusions 8 are intended to be connected to other test tubes in any combination. In this case, the combination of three or more can be independent without using a test tube stand.

  FIG. 9 shows notches 7 and protrusions 8 for a jigsaw provided in the connecting part 3 of the connected test tubes 1.

Industrial applicability

  Since the connected test tube of the present invention has a support portion by a rib, the bottom surface surely faces the irradiation direction with the test tube port as the upper surface against ultraviolet irradiation.

  By connecting single test tubes, preparation work and work time can be shortened.

  In a test tube according to the present invention after resin molding, if the upper film is stuck with the resin film 6 and irradiated with electrons as it is, the sterilized and aseptic state can be maintained unless the upper film is peeled off.

  In the case of ultraviolet irradiation, sterilization can be maintained until just before use by applying the resin film 6 after irradiation.

  In the present invention, the opening of the test tube can be easily maintained in the irradiation direction by fixing the connecting portion during the ultraviolet irradiation.

  In the present invention, since the connecting portion has the holding portion 3 on the outer periphery, the holding portion 3 can be handled without directly touching the opening portion 2 of the test tube.

  In the connected test tubes according to the present invention, the connecting portion is colored in advance, so that the sample being tested can be easily identified, and sample errors can be prevented.

  Since the number of test tubes after the inspection is enormous and the cleaning is complicated, the test tubes are generally discarded. Cleaning with a washing machine becomes possible and reuse becomes practical.

  In the test tube of the present invention, as shown in FIG. 5, when three or more connections are made, the test tube stands upright independently without using a test tube stand. The work efficiency and test accuracy can be improved without using many pipe stands.
