Description

Technical Field

[0001] This utility model relates to the field of flow cytometer technology, specifically to a liquid storage mechanism for a flow cytometer. Background Technology

[0002] Flow cytometers are important analytical instruments widely used in life sciences, medical diagnostics, drug development and clinical testing. They achieve multi-parameter, high-throughput analysis and sorting of individual cells or particles through hydrodynamic focusing and optical detection. During the operation of flow cytometers, the reservoir mechanism serves as a key support system, responsible for the storage and supply of sheath fluid, sample solution and washing solution.

[0003] However, the existing technology still has the following shortcomings in use: In the existing technology configuration, the liquid storage device can usually only hold one specific liquid. Therefore, when the experimental process needs to be switched to a different liquid, the operator needs to disassemble the current liquid circuit connection, remove the liquid storage container, install a new liquid storage container and re-establish the liquid circuit connection. This process is not only complicated, but also significantly reduces the experimental efficiency. Utility Model Content

[0011] Furthermore, at least six cover plates are threadedly connected to the top of the multi-cavity hopper, and a handle is also fixedly connected to the top of the multi-cavity hopper through the sorting hopper.

[0012] The beneficial effects of this utility model are: the multi-cavity bottle can be rotated by manually rotating the handle, thereby adjusting the position of the multi-cavity bottle and improving the usage effect.

[0013] Furthermore, the chamber is connected to the output pipe, and the sleeve, the central pipe, and the water pump are connected.

[0014] The beneficial effect of this utility model is that the water pump can discharge the liquid flowing into the central pipe, which helps to improve work efficiency.

Details are set forth in the following description for purposes of explanation. It should be understood that those skilled in the art will recognize that the present invention can be implemented without using these specific details. In other instances, well-known structures and processes will not be described in detail to avoid obscuring the description of the present invention with unnecessary detail. Therefore, the present invention is not intended to be limited to the embodiments shown, but is consistent with the broadest scope of the principles and features disclosed in this application.

[0024] Example 1 like Figure 1 , Figure 3 As shown, the device includes a central base 100, a sorting container 101 fixedly connected above the central base 100, a multi-chamber container 102 rotatably connected inside the sorting container 101, and at least six chambers 103 inside the multi-chamber container 102. An output pipe 104 is fixedly connected inside the chamber 103, and a solenoid valve 105 is connected to the output pipe 104. A delivery assembly for cooperating with the output pipe 104 is connected inside the central base 100. The delivery assembly includes a central pipe 110 fixedly connected inside the central base 100, a sleeve 111 fixedly connected to one end of the central pipe 110, and a water pump 112 fixedly connected to the other end. A sealing ring 113 is fixedly connected below each chamber 103, and the sealing ring 113 cooperates with the sleeve 111. Various reagents or samples can be pre-loaded in the six chambers 103, and then the liquid can be transferred in conjunction with the delivery assembly, which helps to improve the efficiency.

[0025] Example 2 Based on Embodiment 1, the present invention can be further improved in the following ways, such as... Figure 1 , Figure 3 and Figure 4 As shown, at least six south pole magnets 120 are fixedly connected to the bottom of the multi-chamber container 102, and a north pole magnet 121 is fixedly connected inside the concentrator 100. The north pole magnet 121 cooperates with the south pole magnet 120. At least six cover plates 122 are threadedly connected to the top of the multi-chamber container 102. A handle 123 is fixedly connected to the top of the sorting container 101. The output end of the handle 123 is fixedly connected to the multi-chamber container 102. By turning out the cover plate 122, liquid can be added into the multi-chamber container 102, making it more convenient to use.

[0026] Example 3 Based on Embodiment 2, the present invention can be further improved in the following ways, such as... Figure 3 and Figure 4As shown, chamber 103 is connected to output pipe 104, sleeve 111, central pipe 110 and water pump 112 are connected, and an exhaust valve 124 is provided on the central seat 100. By opening output pipe 104, the liquid inside the corresponding chamber 103 can be discharged, improving the usage effect.

[0027] Specifically, when using the device: First, the operator unscrews the cover plate 122 from the multi-chamber container 102, pours different liquids into each independent chamber 103, and locks the cover plate 122. Then, the name of the corresponding liquid is pasted on the cover plate 122. When it is necessary to call the liquid from a specific chamber 103, the multi-chamber container 102 is rotated by the handle 123. When the output pipe 104 of the target chamber 103 moves into the fixed sleeve 111 with the rotation, the north pole magnet 121 attracts the south pole magnet 120. At this time, the closing ring 113 of the chamber 103 and the sleeve 111 are precisely aligned, forming a reliable dynamic connection. The system forms a sealed interface to effectively prevent liquid leakage. At this time, under the action of magnetic attraction, the rotation angle of the multi-chamber reservoir 102 is limited. Then, the water pump 112 is started and the solenoid valve 105 of the corresponding output pipe 104 is opened. The liquid in the target chamber 103 flows into the central pipe 110 through the output pipe 104 under negative pressure and is finally discharged by the water pump 112. This process realizes rapid and sealed switching of liquid, which significantly improves work efficiency. When it is necessary to switch to another chamber 103, the corresponding solenoid valve 105 is closed first. The system repeats the above steps to complete the convenient replacement of liquid, making it more convenient to use.
