[0002] Immunoassay is a process of qualitatively and quantitatively determining immune molecules and immune cells, and the clinical significance can be analyzed according to the test results. Immunoassay includes cellular immunity detection and humoral immunity detection. When performing humoral immunity detection, it is necessary to sample the liquid, so a sampling tube is required.

[0003] The existing sampling tube has a relatively simple structure. The piston in the sampling tube is driven by a pull rod to move for sampling the liquid. However, this sampling tube has some disadvantages. When sampling, it is not easy to quantitatively control the sampling measurement. The operator needs to observe the sampling volume while sampling, and when pulling the piston by the pull rod, the movement stability of the pull rod is poor. Summary of the Utility Model

The outer wall of the piston contacts the inner wall of the tube body. The top end of the pull rod is fixedly connected with a pull handle. Two groups of fixed pieces are symmetrically fixedly connected to the front and rear of the outer wall of the top of the tube body. The stabilizing mechanism includes two groups of racks. Two groups of U-shaped guiding grooves are symmetrically fixedly connected to the left and right of the outer wall of the tube body. The top ends of the two groups of racks are respectively fixedly connected to both sides of the bottom of the pull handle.

When the threaded adjusting tube drives the adjusting plate to move upward, the sampling volume increases, and vice versa. Adjust the position of the adjusting plate inside the tube body according to the scale value to adjust the amount of sampling. After adjustment, first push the piston to the bottom of the tube body through the pull rod, then hold the tube body by hand, and place the index finger and middle finger against the lower part of the fixed piece. Insert the liquid extraction syringe into the liquid to be sampled, and pull the pull rod with the other hand to drive the piston to move until the top of the piston contacts the bottom end of the adjusting plate, then the quantitative sampling can be completed. Thus, it is convenient to quantitatively control the sampling measurement without observing while extracting. When extracting, the pull rod drives the rack to move, so that the rack drives the gear to rotate through meshing, and the rack drives the guiding slider to slide on the U-shaped guiding groove.
