[0038] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0039] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific implementation methods disclosed below.

[0040] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below with reference to the accompanying drawings.

[0041] See also Figure 1-5 As shown, this embodiment is a cell lipidomics detection sampling device, comprising:

[0042] A test tube assembly, the test tube assembly comprising a test tube body 101;

[0043] A straw assembly, the straw assembly includes a straw body 201, a glass rod 202, a piston 203 and a grip rod 204;

[0044] The middle of the test tube body 101 is movably connected to the straw body 201, the middle of the straw body 201 is movably connected to the glass rod 202, the bottom of the glass rod 202 is fixedly installed with a piston 203, and the top of the glass rod 202 is fixedly installed with a gripping rod 204;

[0045] The test tube body 101 is used to place the cell solution, and the glass rod 202 is used to install the piston 203. The piston 203 moves in the pipette body 201 to generate suction.

[0046] The piston 203 is made of rubber material, and the diameter of the piston 203 is larger than the inner diameter of the straw body 201;

[0047] The size setting of the above components can ensure that the piston 203 can smoothly generate the force when moving;

[0048] The length of the glass rod 202 and the height of the piston 203 are greater than the length of the straw body 201;

[0049] The dimensions of the above components can ensure that sufficient cell fluid can be extracted;

[0050] The straw assembly also includes a scale mark 205;

[0051] The scale lines 205 are evenly spaced and distributed on the outer circle of the straw body 201;

[0052] The installation of the scale line 205 facilitates the marking and observation of the volume of the extracted cell fluid;

[0053] Working principle: insert the glass rod 202 equipped with the piston 203 and the grip 204 into the pipette body 201, then insert the pipette body 201 into the test tube body 101, hold the grip 204, and pull the glass rod 202 outwards. At this time, the glass rod 202 drives the piston 203 to move in the pipette body 201. Under the action of the pressure difference, the cell fluid in the test tube body 101 is sucked into the pipette body 201, and the volume of the cell fluid can be observed through the scale line 205.

[0054] This step can ensure that the test tube body is isolated from the outside world, thereby preventing the external environment from contaminating the cell lipidome during sampling.

[0055] See also Figure 1-5 As shown, this embodiment is based on the above embodiment 1 and further includes a fixed density component;

[0056] The fixed density assembly includes a threaded barrel 301 and a screw column 302;

[0057] A threaded barrel 301 is fixedly installed on the top of the test tube body 101, and a screw column 302 is fixedly installed on the outer ring of the pipette body 201, and the screw column 302 is connected to the threaded barrel 301;

[0058] With the cooperation of the threaded barrel 301 and the screw column 302, a stable connection can be achieved between the test tube body 101 and the pipette body 201, so as to facilitate the subsequent direct sampling operation;

[0059] The fixed density assembly also includes a sealing ring 303;

[0060] A sealing ring 303 is fixedly installed on the top of the screw column 302;

[0061] The provision of the sealing ring 303 improves the air tightness of the test tube body 101 and can prevent the external environment from contaminating the cell fluid;

[0062] The fixed density component also includes anti-skid particles 304;

[0063] The inner ring of the sealing ring 303 is provided with anti-skid particles 304;

[0064] The anti-skid particles 304 can increase the friction force of the inner ring of the sealing ring 303, thereby preventing the sealing ring 303 from falling off the glass rod 202;

[0065] Also included is a support assembly;

[0066] The supporting assembly includes a rubber block 401, a placement groove 402 and a suction cup 403;

[0067] A placement groove 402 is provided in the middle of the rubber block 401, and a suction cup 403 is fixedly installed at the bottom of the rubber block 401;

[0068] A suction cup 403 is installed at the bottom of the rubber block 401 to fix and place a single test tube body 101;

[0069] Working principle: Screw the screw column 302 into the threaded barrel 301 to achieve a stable connection between the test tube body 101 and the pipette body 201. At this time, the sealing ring 303 contacts the threaded barrel 301 to achieve a sealing effect. When a single test tube body 101 needs to be fixed and placed, the suction cup 403 at the bottom of the rubber block 401 is sucked on the table, and then the test tube body 101 is inserted into the placement groove 402;

[0070] This step can firmly connect the test tube body and the straw body when not in use, making it convenient for subsequent direct sampling operations.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
