Problems solved by technology

[0003] At present, the existing sorting analysis and sorting equipment has a complex structure, and it is impossible to achieve sample mixing and control the temperature of the sample liquid during the sorting process, so that the activity of biological particles in the sample liquid cannot be maintained, and for sample separation The replacement of the selected test tubes is also cumbersome, time-consuming and labor-intensive, and the degree of automation is not high, so it is necessary to design a sample loading device involving analysis and sorting equipment

Embodiment 1

[0044] Please refer to figure 1The sample loading device in Embodiment 1 of the present invention includes a first drive device 1, a test tube carrier 2, a bin body 5, and a sample feeding device 6, the first drive device 1 is connected to the test tube carrier 2, and the test tube carrier 2 is used to carry the test tube 4, the interior of the test tube 4 can place the sample liquid, and the sample feeding device 6 is arranged in the chamber body 5.

[0045] Please refer to figure 1 and figure 2 , first describe the specific structure of the first driving device 1 as follows:

[0046] The first driving device 1 includes a first cylinder 101, the piston rod of the first cylinder 101 is connected with the first piston 102, and the first cylinder 101 can drive the piston rod and the first piston rod connected with the piston rod after ventilation. The piston 102 moves up and down in the vertical direction, wherein the movable stroke of the piston rod driven by the first cyli...

Embodiment 2

[0079] The second embodiment is mostly the same in structure and working process as the first embodiment, and the differences are as follows:

[0080] Please refer to Figure 10 , in order to realize that a part of the test tube carrier 2 is no longer suspended in the air and the installation is stable, in the second embodiment of the present invention, the first driving device 1 no longer drives the test tube carrier to move vertically, and the first driving device 1 drives the test tube carrier 2 moves in the horizontal direction, and the tail of the test tube carrier 2 is connected to the output end of the first driving device 1. Preferably, the first driving device 1 specifically adopts a cylinder and is arranged in the horizontal direction, wherein the first driving device 1 Several supporting bases 16 are arranged at the bottom to ensure the stability of the first driving device 1 . A pair of second guide rails 171 are connected to the bottom of the test tube carrier 2,...

Abstract

The invention relates to a sample loading device and analysis and sorting equipment comprising the same, the sample loading device comprises a test tube carrier, a first driving device, a bin body and a sample injection device, the test tube carrier for bearing test tubes can be driven by the first driving device so as to realize that the test tubes extend into or out of a hollow part, when the test tubes are positioned in the hollow part, sample liquid in the test tubes is transferred from the sample injection device to a flow chamber through a power source. The invention further provides analyzing and sorting equipment, the analyzing and sorting equipment comprises the sample loading device, the flow chamber, a detection module, a control module and a sorting module. The sample liquid is driven by positive pressure to be transferred to the flow chamber by adopting the power source, so that automatic sample loading of the sample liquid is realized, and the automation degree is high. By adding a liquid path mechanism, the constant-temperature environment of the hollow part of the bin body can be ensured, so that the activity of biological particles in sample liquid can be kept after the test tubes enter the hollow part, the analyzing and sorting performance of the analyzing and sorting equipment is improved, and the cost is reduced.

Description

technical field [0001] The invention relates to the field of analysis and separation equipment, in particular to a sample loading device and analysis and separation equipment including the device. Background technique [0002] Analysis and sorting equipment is a device for automatic analysis and sorting of cells, which can quickly measure, store, and display a series of important biophysical and biochemical characteristic parameters of dispersed cells suspended in liquid, and can be used according to preselected The parameter ranges from which the specified cell subpopulations are sorted. [0003] At present, the existing sorting analysis and sorting equipment has a complex structure, and it is impossible to achieve sample mixing and control the temperature of the sample liquid during the sorting process, so that the activity of biological particles in the sample liquid cannot be maintained, and for sample separation The replacement of the selected test tubes is also cumber...
