Description

Technical Field

[0001] This utility model relates to the field of cell sorting instrument technology, specifically a cell sorting instrument with overheat protection. Background Technology

[0002] A cell sorter is a scientific instrument used to precisely separate specific types of cells. Simply put, it is based on the principle of flow cytometry. First, the mixed cell fluid is made into a single-cell suspension. Then, the size, shape, or fluorescent labeling of the cells is identified by detection methods such as lasers. Subsequently, the target cells are separated from other cells by electric fields or microfluidic technology and finally collected into a designated container. It is mainly used in biological and medical research, such as separating immune cells, stem cells, or diseased cells, to help scientists study cell function, disease mechanisms, or develop targeted treatments. It is one of the important tools in the life sciences.

[0003] Existing cell sorters, lacking ventilation mechanisms for the internal structure, cannot dissipate heat during long-term sorting processes, causing it to gradually accumulate inside the instrument. This heat accumulation becomes more pronounced as working time increases, and the sensors may experience signal fluctuations when heated, affecting the accuracy of identifying cell size, morphology, and other characteristics. In view of this, we provide a cell sorter that is protected against overheating. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a cell sorting instrument that is protected against overheating failure.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a cell sorting instrument with overheat protection, comprising a cell sorting platform. Multiple upper solenoid valves are fixedly connected to one side of the outer wall of the cell sorting platform, and multiple lower solenoid valves are simultaneously fixedly connected to one side of the top surface of the cell sorting platform. Multiple liquid bag hooks are fixedly connected to the outer wall of the top of the cell sorting platform, and a display screen is fixedly connected to one side of the top surface of the cell sorting platform. A peristaltic pump is fixedly connected to one side of the top surface of the cell sorting platform, and a pipe clamp is fixedly connected to one side of the top surface of the cell sorting platform. Multiple rectangular windows are provided on both sides of the outer wall of the cell sorting platform, and multiple filter screens are provided on the inner wall of the rectangular windows. Multiple guide rails are fixedly connected to the inner wall of the cell sorting platform, and an adjusting component is provided on one side of the outer wall of the guide rails. A sliding module is added to one side of the outer wall of the adjusting component. Multiple sliding grooves are simultaneously provided on both sides of the outer wall of the cell sorting platform, and multiple through grooves are provided on one side of the outer wall of the adjusting component.

[0006] As described above, one side of the outer wall of the sliding module penetrates the interior of the sliding groove, and one side of the outer wall of the sliding module extends to one side of the outer wall of the cell sorting station.

[0007] The outer wall of the sliding module is tightly fitted to the inner wall of the sliding groove, and the outer wall of the sliding module is slidably connected to the inner wall of the sliding groove.

[0008] As described above, the outer wall of the filter screen is fixedly connected to the inner wall of the rectangular window.

[0009] As described above, the plurality of through grooves correspond to each other with the filter screen, the spacing between the plurality of through grooves is equal to the spacing between the filter screens, and the width of the through grooves is consistent with the width of the filter screens;

[0010] The multiple through-slots are interwoven with the filter screen.

[0011] As described above, the multiple guide rails are located on both sides of the outer wall of the adjusting component, and one side of the outer wall of the guide rail is in close contact with one side of the outer wall of the adjusting component.

[0012] As described above, multiple strong magnetic positioning components are fixedly connected to both sides of the inner wall of the cell sorting stage, and the multiple strong magnetic positioning components are respectively located on both sides of the outer side of the adjustment component. Multiple metal components are fixedly connected to both sides of the outer wall of the adjustment component, and the metal components and the strong magnetic positioning components are mutually attracted.

[0013] Compared with existing technologies, this cell sorting instrument with overheat protection has the following advantages:

[0014] I. When the cell sorting station continuously screens and identifies cells, if the temperature rises to the point where heat dissipation is required, the operator can push the sliding modules on both sides to adjust the components to move smoothly along the guide rail. As the through slot and the rectangular window gradually align, outside air, after being filtered by the filter screen, enters the instrument through the through slot, quickly carrying away the accumulated heat. This reduces the occurrence of signal fluctuations in the sensor due to overheating, which affects the recognition accuracy of cell size, morphology, and other characteristics, and improves the reliability of the device when identifying and separating cells.

[0015] Second, when the adjusting component moves to the target position with the sliding module, the metal part on one side of the device will be tightly attracted to the strong magnetic positioning part on the inner wall of the cell sorting table, ensuring that the rectangular window remains open and closed, and further improving the stability of the device during operation.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figures 1-5 As shown, this utility model provides a cell sorting instrument technical solution to prevent overheating failure: A cell sorting instrument to prevent overheating failure includes a cell sorting platform 1. Multiple upper solenoid valves 101 are fixedly connected to one side of the outer wall of the cell sorting platform 1, and multiple lower solenoid valves 102 are simultaneously fixedly connected to one side of the top surface of the cell sorting platform 1. Multiple liquid bag hooks 103 are fixedly connected to the outer wall of the top of the cell sorting platform 1, and a display screen 104 is fixedly connected to one side of the top surface of the cell sorting platform 1. A peristaltic pump 105 is fixedly connected to one side of the top surface of the cell sorting platform 1. Furthermore, a pipe clamp 106 is fixedly connected to one side of the top surface of the cell sorting table 1. Multiple rectangular windows 2 are opened on both sides of the outer wall of the cell sorting table 1, and multiple filters 201 are installed on the inner wall of the rectangular windows 2. Multiple guide rails 202 are fixedly connected to the inner wall of the cell sorting table 1, and an adjustment component 203 is installed on one side of the outer wall of the guide rail 202. A sliding module 204 is added to one side of the outer wall of the adjustment component 203. Multiple sliding grooves 205 are opened on both sides of the outer wall of the cell sorting table 1, and multiple through grooves 206 are opened on one side of the outer wall of the adjustment component 203.

[0025] When the cell sorting station 1 continuously screens and identifies cells, the operator pushes the sliding modules 204 on both sides, which in turn moves the adjustment component 203 fixed thereto. As the through slot 206 gradually aligns with the rectangular window 2, when the adjustment component 203 moves to the target position with the sliding module 204, the metal part 208 will be attracted to the strong magnetic positioning component 207 on one side of the inner wall of the cell sorting station 1, keeping the rectangular window 2 in the open or closed state.

[0026] like Figure 1 As shown, one side of the outer wall of the sliding module 204 penetrates the interior of the sliding groove 205, and one side of the outer wall of the sliding module 204 extends to one side of the outer wall of the cell sorting station 1.

[0027] The outer wall of the sliding module 204 is tightly fitted to the inner wall of the sliding groove 205, and the outer wall of the sliding module 204 is slidably connected to the inner wall of the sliding groove 205.

[0028] The sliding connection between the sliding module 204 and the sliding groove 205 allows operators to adjust the opening and closing of the ventilation opening according to actual temperature requirements.

[0029] like Figure 1 As shown, the outer wall of filter 201 is fixedly connected to the inner wall of rectangular window 2.

[0030] The filter 201 is fixedly connected inside the rectangular window 2, which can block dust, debris and other impurities from entering the instrument to the greatest extent.

[0031] like Figure 1 As shown, multiple through slots 206 correspond to each other with filter screens 201, the spacing between multiple through slots 206 is equal to the spacing between filter screens 201, and the width of through slots 206 is the same as the width of filter screens 201.

[0032] Multiple through slots 206 are interwoven with the filter screen 201.

[0033] The corresponding staggered structure of the through groove 206 and the filter screen 201 can be adjusted by moving the adjustment component 203 to change the overlapping area of ​​the two, so as to control the opening and closing state of the rectangular window 2.

[0034] like Figure 1 As shown, multiple guide rails 202 are located on both sides of the outer wall of the adjusting member 203. One side of the outer wall of the guide rail 202 is in close contact with one side of the outer wall of the adjusting member 203.

[0035] The guide rail 202 is mainly used to provide a constraint effect on the movement trajectory of the adjustment component 203, provide guidance support for its movement, and reduce the jamming that occurs during the movement process.

[0036] like Figure 1As shown, multiple strong magnetic positioning components 207 are fixedly connected to both sides of the inner wall of the cell sorting stage 1, and the multiple strong magnetic positioning components 207 are located on both sides of the outer side of the adjustment component 203. Multiple metal components 208 are fixedly connected to both sides of the outer wall of the adjustment component 203, and the metal components 208 and the strong magnetic positioning components 207 are mutually attracted.

[0037] The magnetic positioning component 207 and the metal component 208 are connected by an adsorption relationship, which can fix the adjusting component 203 in the target position and ensure that the rectangular window 2 remains open or closed.

[0038] Working principle: When the cell sorting station 1 is working continuously, if its internal temperature rises to the point where heat dissipation is required, the operator can push the sliding modules 204 on both sides of the cell sorting station 1, which will drive the adjustment components 203 fixedly connected to them to move synchronously. As the adjustment components 203 move, the through grooves 206 on their outer walls gradually align with the filter screen 201 in the rectangular window 2. The overlapping area between the through grooves 206 and the filter screen 201 increases. After the external air is filtered by the filter screen 201 to remove dust and debris, it enters the cell sorting station 1 through the through grooves 206, comes into contact with the high-temperature area and carries away the heat. When the sliding modules 204 reach the target position, the metal parts 208 on the outer wall of the adjustment components 203 will be attracted and fixed by the strong magnetic positioning parts 207 on the inner wall of the cell sorting station 1, ensuring that the through grooves 206 and the rectangular window 2 remain in a continuous state. After the internal heat is gradually dissipated with the air flow and the temperature drops to a suitable range, the cell sorting station 1 resumes stable operation.

[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
