However, when the reagent enters the perfusion head from the reagent box through the delivery tube, an impact force is generated, causing the perfusion head to shake, resulting in the reagent easily splashing during perfusion. Therefore, it is urgent to design a perfusion structure for reagent packaging to solve the above problem. Utility Model Content

[0027] Working principle:

[0028] When using the perfusion structure for reagent packaging, first place the perfused reagent tube 213 on the upper end of the tray 212, and then perfuse the reagent in the reagent box 211 into the reagent tube 213 through the delivery tube 214 from the perfusion head 215. When the reagent enters the perfusion head 215 through the delivery tube 214, the second fixed plate 217 drives the support column 219 to move downward, causing it to squeeze the spring 222, which is used for buffering. At the same time, the force is transmitted to the damper 223 for decomposition, so as to prevent the generated force from causing the perfusion head 215 to shake, causing splashing during perfusion.

[0029] When the filling mechanism is used to fill the reagent tubes 213, multiple groups of reagent tubes 213 can be inserted into the limiting cavity 229 at the same time, and the servo motor 114 is started to drive the rotating rod 315 to rotate, thereby driving the tray 212 to rotate, which can drive the reagent tubes 213 placed on the tray 212 to rotate synchronously, so that multiple groups of reagent tubes 213 can be filled and unloaded at the same time, thereby improving the filling efficiency.
