Description

[Detailed description of the invention] This invention relates to a test tube transport device used for transporting a large number of test tubes containing samples and transferring them to an analytical device.

Conventionally, in clinical laboratories of hospitals, about 50 test tubes 1 containing samples such as serum are placed in a wire mesh basket as shown in Fig. 1, and transported as shown in Fig. 2, which forms part of the automatic sampler of an analyzer. The test tubes were transferred from the wire cage to a turntable as shown in Figure 3 or to a test tube feeding device connected by a flexible chain as shown in Figure 3, and then passed through the analyzer.

When using this method, it is necessary to transfer a large number of test tubes to a test tube feeding device such as an analyzer, and when it is necessary to keep the test tubes in the correct order during transfer, it is necessary to change the sample order. There is a risk of confusion and mistakes.

This device makes it possible to omit the above-mentioned transfer operation for a large number of test tubes, and therefore eliminates confusion and mistakes in the order of samples when transferring test tubes. The purpose is to provide a test tube carrying device that serves both as a flexible chain and a test tube holding frame consisting of several rectangular test tube holding frames each having a plurality of test tube holding holes arranged at predetermined intervals. A test tube carrying device consisting of a group of test tube holding frames connected in a zigzag manner with hinges at their diagonal corners, and a box serving as a holder for storing and holding a collection of folded test tube holding frames. It is.

Hereinafter, one embodiment of this invention will be described in detail based on the drawings.

Figure 4 shows a group of test tube holding frames in which the test tube holding frames are connected in a staggered manner with hinges at their diagonal corners, taken out onto the table of the test tube feeding device of the analyzer, unfolded, and continuously connected in a train shape. FIG. 6 is an explanatory plan view showing a state in which the test tube holding frame is sequentially applied to the feeding mechanism.

In the figure, 1 is a test tube, 2 is a test tube holding frame, 3 is a hinge,
4 is a feed drive gear of the test tube holding frame feed mechanism, and 5 is a population guide plate of the feed mechanism.

Figure 5 shows the test tube holding frame group containing the test tube 1 on the hinge 3.
FIG. 6 is a plan view showing the state in which the receivers are folded at the joints and stacked in a rectangular shape, and the receivers are housed in the box 6. FIG.
7 is a side view taken in the direction of the arrow VllVII in FIG. 5. FIG.

In Figures 6 and 7, 1 is a test tube, 2 is a test tube holding frame,
6 is a box, 7 is a handle, 8 is a window for photometry, and 9 is a hooking hole for a feed drive gear.

The feed drive gear hook holes 9 are through holes drilled on both lower sides of the long side of the test tube holding frame 2 at intervals equal to the feed pitch of the feed drive gear 4, and the through holes at both left and right ends are hinged. Needless to say, gaps are provided between the connected test tube holding frames so that the test tube holding frames 2 can be smoothly fed by the feed driving gear 4.

Further, the photometry window 8 is a through hole bored in both sides of the center of the longitudinal side of the test tube holding frame 2 corresponding to the test tube holding hole, and as shown in FIG. pull out from
When unfolding the tube and applying it to the feed mechanism of the analyzer, a test was performed using the conventional flexible chain feed mechanism to perform a measurement that was exactly the same as the absorbance measurement by passing light through the test tube from the side, as shown by arrow P in Figure 3. This allows the test to be carried out at a predetermined position while the tube is held in the test tube holding frame.

In the above-mentioned absorbance measurement, sampling of the sample indicated by arrow S is also carried out on the turntable of an automatic sampler used in the conventional analyzer shown in Fig. 2, or in the feeding mechanism using a conventional flexible chain shown in Fig. 3. Similarly, it can be implemented at a predetermined position of the feeding mechanism according to the invention.

In the above-mentioned absorbance measurement, for example, if a pre-process of adding a reagent to serum collected in a test tube and placing it in a constant temperature water bath for reaction is required, the test tube holding frame 2 is placed in the accumulation state shown in FIG. You can operate with .

The receiving box 6 can be configured such that one end thereof can be opened, and the test tube holding frame 2 can be sequentially drawn out from that part.

Also, instead of a box, a simple framework can perform this function.

Further, the hinge support pin of the connecting hinge may be made detachable so that the test tube holding frame 2 can be separated individually.

As is clear from the above description, according to the test tube transport device of this invention, when a large number of test tubes are sequentially passed through the feed mechanism of an analyzer, the operation of transferring test tubes can be omitted. In addition, it is possible to eliminate confusion and mistakes in sample order when transferring test tubes, and to analyze by passing light through the photometry window and measuring the absorbance while the test tubes are housed in the test holding frame in the feeding mechanism. You can also do that.
