Description

[Detailed description of the invention] The present invention relates to a test tube rack in which sample tubes (test tubes) containing, for example, patient's serum etc. can be mounted and can be easily cleaned and sterilized after work is completed. .

In FIG. 1 showing a conventional test tube rack, reference numeral 1 denotes a test tube rack body, and the test tube rack body 1 has mounting holes 8 on its top surface into which standard test tubes 2 arranged in a straight line are inserted. An identification number 7 is attached to the mounting hole 8 so that the standard test tube 2 inserted into the mounting hole 8 can be displayed.

Reference numeral 4 denotes an adapter that is attached when holding a thin test tube 3 that is thinner than the standard, and can be detachably fixed by inserting a screw 5 fixed to the top surface of the test tube rack main body 1 and screwing in a wing screw 6. .

When holding the standard test tube 2, the adapter 4 is removed, and when holding the narrow test tube 3, the adapter 4 is attached to the upper part of the test tube rack main body 1.

However, in such a test tube rack, the abutment 4 is attached to hold the thin test tubes 3, and if a substance that requires disinfection, such as blood, enters between the test tube rack body 1 and the adapter 4 during use, It is necessary to clean and disinfect the adapter, but since this cannot be done smoothly with the adapter attached, it is necessary to loosen the wing nut 6 and remove the adapter 4 each time, which has the disadvantage of poor handling. Ta.

In addition, in the above structure, since the narrow test tube 3 is held only at the upper end by the adapter 4, the narrow test tube 3 may be held diagonally. There was a drawback that such operations could not be carried out smoothly when suctioning up or discharging other samples into test tubes.

Moreover, the identification number 7 written on the top surface of the test tube rack main body 1 was also covered by the adapter 4 and could not be confirmed.

The purpose of this invention is to eliminate the above-mentioned drawbacks, and to provide a test tube rack that allows easy attaching and detaching of adapters, easy cleaning, mounting of narrow test tubes in the correct position, and reliable reading of identification numbers. be.

The test tube rack of the present invention is formed by attaching an adapter to the test tube rack main body having a plurality of standard test tube attachment holes arranged in a straight line so that thin test tubes can be attached thereto. The side adapter and the bottom adapter, which hold a plurality of thin test tubes, are attached to both sides and the bottom of the linearly arranged openings of the test rack main body so that they can be attached and detached with a single touch operation.

Hereinafter, an embodiment of the test tube rack of the present invention will be described with reference to FIG. 2, in which the same parts as those of the conventional test tube rack are denoted by the same reference numerals.

Side wall adapters 10, 11 and a bottom adapter 9, which are made of rubber or plastic and can be attached and detached with a single touch operation, are attached to both upper sides and the bottom of the test tube rack body 1 as shown by the arrows. There is.

As shown in FIG. 3, the bottom adapter 9 is provided with a capillary bottom concave seat 12 for accommodating the bottoms of a plurality of narrow test tubes 3.
Further, the side wall adapter 10.11 has a thin tube support curved surface 13 formed on its inner surface to hold the thin test tube 3 from the side.

A standard test tube bottom adapter (not shown) can also be attached to and removed from the bottom of the test tube rack body 1, and the standard test tube bottom adapter is attached when not holding the narrow test tubes 3. It looks like this.

Since the test tube rack of this embodiment is configured in this way, when the bottom adapter 9 and the side wall adapters 10 and 11 are attached to the test tube rack main body 1 and the narrow test tube 3 is held, The core is installed in the correct position matching the mounting hole 8 without being slanted as shown in the figure.

Therefore, it is easy to automatically suck up the sample inside the test tube with the nozzle and discharge other samples into the inside, and each adapter can be easily attached and detached with one-touch operation for cleaning and disinfection. Since the process can be carried out in a number of steps, the ease of handling is also significantly improved.

Since the identification number on the test tube rack body is not covered by the adapter, the identification number can be read in the same way as when holding the standard test tube 2.

As described above, the test tube rack of the present invention has features such as easy attaching and detaching of adapters, easy cleaning, etc., as well as being able to mount narrow test tubes in the correct position matching the mounting holes and reliably read identification numbers. It is effective.
