The advantages of the guide groove 31 arranged in the above manner are: when the guide plate 3 moves upwards or downwards, each adding pipe 1 moves horizontally because each guide groove 31 presses the corresponding connecting rod 82 to move the corresponding connecting rod (in the process, the first slide block 4 moves along the first guide rail 62, so that the adding pipe 1 can only move horizontally), namely, the position of each adding pipe 1 is controlled by the guide groove 31, and in order to keep the distance between every two adjacent adding pipes 1 equal at all times, the distance between any two adjacent guide grooves 31 in the same horizontal direction needs to be ensured to be equal, meanwhile, in order to realize that the distance between every two adjacent adding pipes 1 can be adjusted, the distance between every two adjacent guide grooves 31 in the height direction needs to be ensured to be gradually changed, so that when the guide plate 3 moves vertically, the distance between every adding pipe 1 changes gradually, meanwhile, the distance between the adjacent adding pipes 1 is kept equal all the time, fig. 8 shows a state when the guide plate 3 moves downwards to the lowest point, and the distance between the adjacent adding pipes 1 is at the maximum, and fig. 9 shows a state when the guide plate 3 moves upwards to the highest point, and the distance between the adjacent adding pipes 1 is at the minimum.

This example is mainly used to simultaneously add physiological saline to a plurality of test tubes containing leucorrhea samples in batches. When the quantity of leucorrhea sample is more, adopt this embodiment can add normal saline to a plurality of test tubes that are equipped with the leucorrhea sample simultaneously fast, compare the current operation mode of adding one by one, can raise the efficiency greatly, save operating time. The application method of the embodiment is specifically as follows:

the test tube rack is used for fixing a plurality of test tubes with leucorrhea samples; the structural form of the test tube rack can be seen in the Chinese patent with an authorization publication number of CN3591568D applied by Shenzhen Merrill biomedical electronics Limited, and the test tubes can be arranged in a row at equal intervals; unlike the above patent, in this embodiment, since the number of the adding tubes 1 is eight, the number of the fixing clamps of the test tube rack should also be eight instead of ten shown in the above patent;

before use, a certain amount of normal saline needs to be poured into the container 2 in advance, and the normal saline enters the container 2 and then enters the adding pipes 1 through the pipelines 2 a;

when in use, firstly, a plurality of test tubes filled with leucorrhea samples are placed on a test tube rack; then, placing the test tube rack in the test tube placing area 92 at the front side of the shell 9, and after placing, ensuring that each test tube on the test tube rack is aligned with the outlet of one of the adding tubes 1;

after the test tube rack is placed, pressing a second button 932 of the display control panel 93 by hand; then, the control module controls each valve 1a to be opened, so that the physiological saline which enters each adding pipe 1 from the container 2 in advance flows out from the outlet of the adding pipe 1, the valve 1a is automatically closed after a short time interval, and a certain amount of physiological saline is added into each test tube after the valve 1a is closed; then, taking out the test tube rack from the test tube placing area 92, then taking down each test tube from the test tube rack, then shaking the test tubes to fully dissolve the leucorrhea sample and the normal saline, then dipping the leucorrhea solution in the test tubes with a cotton swab and smearing the leucorrhea solution on a glass slide of a microscope, and then observing the visible components in the leucorrhea solution through the microscope to judge whether the abnormal leucorrhea condition exists;

because the test tube rack can have various specifications and sizes, the test tube racks with different specifications can have different distances between the fixing screens for placing test tubes, but in the same test tube rack, the distances between the adjacent fixing screens are generally equal, for example, the test tube rack with six fixing screens has the distance between the central lines of the adjacent fixing screens of 3.5cm, the test tube rack with eight fixing screens has the distance between the central lines of the adjacent fixing screens of 2.5 cm; therefore, in order to adapt the present embodiment to test tube racks with different specifications, the distance between the adding tubes 1 needs to be adjustable. In this embodiment, the first slider 4, the second slider 5, the bottom plate assembly 6, the driving mechanism 7, the connecting member 8 and other components are specially added to realize the function of adjusting the distance between the adding pipes 1; when the device is used, the screw rod 72 can be rotated only by rotating the knob 78 by hand, and then the threaded sleeve 71 can move along the screw rod 72 to drive the bottom plate 3 to move upwards or downwards, when the bottom plate 3 moves vertically, each guide groove 31 of the bottom plate 3 can respectively extrude each corresponding connecting rod 82 to force the connecting rods 82 to move, and because the connecting rods 82 connect the adding pipes 1 with the first sliding blocks 4 together, and simultaneously the first sliding blocks 4 can only horizontally move along the first guide rails 62, under the extrusion of the guide grooves 31, the adding pipes 1 can horizontally move by means of the matching of the first sliding blocks 4 and the first guide rails 62, so that the distance between the adding pipes 1 can be adjusted; therefore, in use, after replacing test tube racks with different specifications, the user can adjust the distance between the adding tubes 1 by rotating the knob 78 by hand, so that the adding tubes 1 can be aligned with the test tubes below one by one.

In addition, can also design corresponding location structure (not shown in the figure) in test tube placing area 92 to when guaranteeing that the test-tube rack places test tube placing area 92 in, the test-tube rack can obtain corresponding location, and the back of fixing a position, each test tube is located same facade with each interpolation pipe 1, and the liquid that each interpolation pipe 1 flowed out just can directly get into in the test tube of below like this, has removed the trouble of manual regulation test-tube rack position from.

In the description of the present invention, the terms "connect", "mount", "fix", etc. should be interpreted broadly, for example, the term "connect" may be a fixed connection, a detachable connection, or an integral connection; may be directly connected or indirectly connected through an intermediate. The specific meanings of the above terms in the present invention can be understood by those skilled in the art according to specific situations.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
