Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading devices, in particular to an automatic loading and unloading device for a flow cytometer. Background Technique

[0002] A flow cytometer is a device for automatically analyzing and sorting cells. It can quickly measure, store, and display a series of important biophysical and biochemical characteristic parameters of dispersed cells suspended in a liquid, and can sort out specified cell subsets according to a preselected parameter range.

[0003] In the automatic loading and unloading device for a flow cytometer with the application number 202321704737.2, it is proposed that the existing sample loading method overly relies on manual labor. Workers need to operate the sample tubes one by one for loading and unloading. Therefore, during the experiment, staff members always need to be on duty in the sample loading area of the flow cytometer, resulting in low work efficiency. Moreover, when the number of samples to be detected is large, the labor intensity of the staff is relatively high. By designing a lifting device to control the lifting of the loading tray, the action of automatically inserting or pulling out the sample tube into or from the sampling hole is realized. And through a rotating device, the rotation of the loading tray is realized, thus realizing the automatic replacement of the sample tube. There is no need for the operator to be on duty in the sample loading area for special loading and unloading. After placing the samples to be detected on the loading tray, the automatic loading and unloading device of the flow cytometer can automatically load and unload the samples. During the sample loading and replacement, the operator can concentrate on other tasks, greatly improving the work efficiency of the laboratory.

[0004] However, when the above device is in use, since the sample tubes are directly exposed to the outside world, the undetected sample tubes may be contaminated, thus affecting the detection effect of the experiment.

[0005] Therefore, in view of the above problems, we propose an automatic loading and unloading device for a flow cytometer. Content of the Utility Model

An upper and lower material device is arranged above the installation plate. An installation groove is opened on the upper surface of the flow cytometer main body. A driving motor is arranged inside the installation groove. An electric push rod is fixedly installed at the bottom of the installation plate.

[0008] As a further description of the present utility model: The loading and unloading device includes a feeding box, a feeding seat is rotatably connected inside the feeding box, a connecting rod is fixedly installed on the upper surface of the feeding seat, a plurality of placement holes are formed around the connecting rod on the upper surface of the feeding seat, and a circular hole for the connecting rod to pass through is formed on the upper surface of the feeding box.

[0009] As a further description of the present utility model: Two through holes are formed on the upper surface of the feeding box, the two through holes are distributed front and back, and the outer diameter of the through holes is larger than the outer diameter of the placement holes.
