Description

Technical Field

[0001] The utility model belongs to the technical field of cell detection, and particularly relates to a cell liquid sample processing device. Background Art

[0002] In cell biology research experiments, it is necessary to detect the concentration (quantitative counting) of cells or other biological particles. The concentration of cell suspension is not only a monitoring parameter for cell culture, but also a necessary parameter in many experimental projects, which affects the smooth completion of biological research experiments.

[0003] Cell detectors usually use the Coulter principle to detect the cell concentration in cell suspension. Before detection, it is necessary to homogenize the cell suspension in the sample tube so that the cells are evenly distributed in the liquid to ensure the accuracy of subsequent detection results. After detection, it is necessary to remove the waste liquid after detection from the sample tube for centralized treatment of the waste liquid. In the prior art, the steps of mixing the cell suspension and removing the cell waste liquid cannot be integrated, resulting in relatively low detection efficiency.

[0004] Therefore, in view of the above technical problems, it is necessary to provide a cell liquid sample processing device. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a cell liquid sample processing device, which can solve the problem of relatively low cell counting detection efficiency mentioned above.

[0006] In order to achieve the above purpose, the technical solution provided by a specific embodiment of the utility model is as follows:

[0007] A cell liquid sample processing device includes a tube body, a moving component, a suction component and a diversion component. The moving component drives the tube body to approach or move away from the sample tube; when the suction component is communicated with the tube body, the suction component makes the cell liquid in the sample tube reciprocally enter or leave the tube body; when the diversion component is communicated with the tube body, the diversion component exports the waste liquid in the sample tube through the tube body.

[0008] In one or more embodiments of the utility model, the moving component includes: a fixing plate; a driving member installed on the fixing plate; a connecting plate slidably connected with the fixing plate and fixedly connected with the output end of the driving member, and the tube body is installed at one end of the connecting plate away from the driving member so that the tube body is aligned with the orifice of the sample tube

[0009] In one or more embodiments of the present utility model, the moving assembly further includes a bottom block and a pressing block.

[0010] In one or more embodiments of the present utility model, the moving assembly further includes a limiting member for limiting the moving direction of the tube body.

[0011] In one or more embodiments of the present utility model, the limiting member includes a limiting block. The limiting block is fixedly connected to the fixing plate. The limiting block is provided with a limiting hole, and the tube body slidably passes through the limiting hole.

[0012] In one or more embodiments of the present utility model, the fixing plate is provided with an avoidance notch on the side away from the driving member.

[0013] In one or more embodiments of the present utility model, the end of the tube body close to the sample tube is necked down to form a spike portion.

[0014] In one or more embodiments of the present utility model, the cell liquid sample processing device further includes a first pipeline connecting the suction member and the tube body, a second pipeline connecting the diversion member and the tube body, and a control member for controlling the opening and closing of the first pipeline or the second pipeline.

[0024] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Refer to Figure 1 , the cell fluid sample processing device in an embodiment of the present invention includes a tube body 1, a moving assembly 2, a suction member 3, and a diversion member 4. The moving assembly 2 drives the tube body 1 to approach or move away from a sample tube (the sample tube is not shown in the figure). When the suction member 3 is communicated with the tube body 1, the suction member 3 enables the cell fluid in the sample tube to reciprocally enter or leave the tube body 1. When the diversion member 4 is communicated with the tube body 1, the diversion member 4 discharges the waste liquid in the sample tube through the tube body 1.

[0026] Refer to Figure 2In the process of detecting the concentration of the cell fluid, the suction piece 3 is first connected to the tube body 1, and then the moving component 2 drives the tube body 1 close to the sample tube, and one end of the tube body 1 is submerged in the liquid surface. Then the suction piece 3 is started to circulate and suck the cell suspension in the sample tube, so that the cell suspension reciprocates into or leaves the tube body 1 with a smaller diameter, so that the cell suspension forms turbulence, so that the cells are evenly distributed in the cell suspension, so as to improve the accuracy of subsequent cell concentration detection. After uniform mixing, the moving component 2 drives the tube body 1 away from the sample tube. In this embodiment, the suction piece 3 is a syringe pump.

[0027] After the cell fluid concentration detection is completed, the flow guide 4 is switched to be connected with the tube body 1, and then the moving assembly 2 drives the tube body 1 to move into the sample tube, and then the flow guide 4 is started to guide the cell waste fluid in the sample tube. In this embodiment, the flow guide 4 can be a hydraulic pump.

[0028] It is understandable that the connection between the tube body 1 and the suction member 3 or the flow guide member 4 can be switched manually by relevant personnel, or can be switched automatically by setting a mechanical device.

[0029] Reference Figure 2 and Figure 3 The tube body 1 is constricted at one end near the sample tube to form a spike portion 11. The spike portion 11 further reduces its caliber, thereby further improving the uniform mixing effect of the cells in the cell suspension. When the guide member 4 draws cell waste liquid from the sample tube, the spike portion 11 can also enhance the suction effect, thereby improving the removal efficiency of the cell waste liquid.

[0030] Reference Figure 2 and Figure 3 The moving assembly 2 includes a fixing plate 21 , a driving member 22 , a connecting plate 23 , a bottom block 24 , a pressing block 25 and a limiting member 26 .

[0031] Reference Figure 2 and Figure 3 , the driving member 22 is installed on the fixed plate 21, and the driving member 22 can be a cylinder. The fixed plate 21 is provided with a notch for avoidance on the side away from the driving member 22. On the one hand, the notch can effectively save material costs, and on the other hand, it can avoid other devices and facilitate installation. The connecting plate 23 is slidably connected to the fixed plate 21, and is fixedly connected to the output end of the driving member 22. The connecting plate 23 and the fixed plate 21 can be slidably connected via a slide rail. The tube body 1 is installed on one end of the connecting plate 23 away from the driving member 22, so that the tube body 1 is aligned with the tube mouth of the sample tube. Therefore, the driving member 22 drives the connecting plate 23 to move, thereby being able to drive the tube body 1 to approach or move away from the sample tube.

[0032] Reference Figure 2 and Figure 3The bottom block 24 is fixedly connected to the end of the connecting plate 23 away from the driving member 22, and a mounting hole 5 for abutting and fixing the pipe body 1 is formed between the pressing block 25 and the bottom block 24, and the pressing block 25 and the bottom block 24 are detachably connected. The combination of the bottom block 24 and the pressing block 25 can effectively fix the pipe body 1.

[0033] Reference Figure 3 The limiting member 26 is used to limit the moving direction of the tube body 1, so that the tube body 1 moves toward or away from the sample tube. Specifically, the limiting member 26 includes a limiting block 261, which is fixedly connected to the fixing plate 21. The limiting block 261 is provided with a limiting hole, and the tube body 1 is slidably arranged in the limiting hole. The limiting block 261 can also reduce the shaking that may occur during the movement of the tube body 1, and further ensure the stability of the movement of the tube body 1.

[0034] Reference Figure 1 In an optional embodiment, the cell fluid sample processing device further includes a first pipeline connecting the suction member 3 and the tube body 1, a second pipeline connecting the flow guide member 4 and the tube body 1, and a control member for controlling the opening and closing of the first pipeline or the second pipeline. In this embodiment, the control member includes a solenoid valve, which is installed in the first pipeline and the second pipeline respectively. The first pipeline, the second pipeline and the solenoid valve are not shown in the figure.

[0035] When the electromagnetic valve in the first pipeline is opened, the suction member 3 is connected to the tube body 1, so that the cell suspension can be mixed. When the electromagnetic valve in the second pipeline is opened, the flow guide member 4 is connected to the tube body 1, so that the cell waste liquid can be extracted and discharged.

[0036] Therefore, by providing a controller, the connection state between the suction member 3 or the flow guide member 4 and the tube body 1 can be automatically switched, thereby further improving the detection efficiency of the cell suspension.

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
