Description

Technical Field

[0001] The utility model relates to the technical field of sampling of cell specimen preservation liquid, in particular to an integrated sampling device for cell specimen preservation liquid. Background Art

[0002] Cell preservation fluid plays the role of maintaining and fixing the original morphological structure of cells and is the basis for pathological cell diagnosis. If the cell morphological structure changes, it may lead to errors in diagnostic results. Therefore, cell preservation fluid is needed to fix the cell morphology. When using cell specimen preservation fluid, it needs to be sampled.

[0003] For example, a biological cell sampling device with the authorization announcement number "CN217930942U" reduces the difficulty of operation for operators by fixing the sample bottle with a clamp. When cells need to be extracted, the valve is closed, the push rod is pulled, and the cells are drawn from the needle into the sampling tube. After the cells are drawn in, the valve is opened, the push rod is squeezed, and the samples are squeezed into the collection bottle through the valve along the pipeline, so that the sampling device can extract a large number of samples at one time, reducing the number of times the sample bottle is opened and the probability of sample cells being contaminated. However, the device fixes the sample bottle with the clamp by sleeve-fitting the outer wall of the sample bottle and rotating the positioning bolt, and it cannot be applied to sample bottles of different sizes. The device extracts the cell specimen preservation solution inside the sample bottle with a needle. Since the liquid level will drop when the cell specimen preservation solution is extracted, the needle of the device needs to be moved to below the liquid level for multiple times before the cell specimen preservation solution can be collected, which increases the workload of the operator and reduces the working efficiency of the device.

[0025] Working principle:

[0026] The operator places the cell specimen preservation solution sample bottle on the surface of the box 1

[0027] Auxiliary fixation process when collecting cell specimen preservation fluid:

[0028] The external power supply of the first hydraulic cylinder 201 is turned on, and the telescopic end of the first hydraulic cylinder 201 is started to shorten to drive the push block 202 to move downward, and the push block 202 drives the connecting rod 203 to move, and the connecting rod 203 pulls the clamping arms 204 closer to each other, and the clamping arms 204 drive the clamping block 206 to press against the surface of the cell specimen preservation fluid sample bottle, and the movement of the telescopic end of the first hydraulic cylinder 201 is stopped.

[0029] Auxiliary collection process when collecting cell specimen preservation fluid:

[0030] The external power supply of the first motor 301 is turned on, and the output shaft of the first motor 301 is started to rotate to drive the worm 303 to rotate. The rotation of the worm 303 drives the worm wheel 304 to rotate. The worm wheel 304 drives the gear 305 to rotate. The gear 305 drives the rack 306 to move downward. The rack 306 drives the support plate 307 to move downward synchronously.

At the same time, the external power supply of the second hydraulic cylinder 6 is turned on, and the telescopic end of the second hydraulic cylinder 6 is started to shorten to drive the push rod 7 to move upward. The push rod 7 moves in coordination with the fixed cylinder 8. The negative pressure generated draws the cell specimen preservation solution inside the cell specimen preservation solution sample bottle and injects it into the fixed tube 8. The one-way valve 9 prevents the cell specimen preservation solution inside the fixed tube 8 from flowing back. When the cell specimen preservation solution inside the fixed tube 8 reaches the demand, the valve between the fixed tube 8 and the hose 11 is opened, and the telescopic end of the second hydraulic cylinder 6 is started to extend again. The push rod 7 pushes the cell specimen preservation solution inside the fixed tube 8 to be transported to the collection tube 13 through the hose 11. The operator detects the cell specimen preservation solution inside the collection tube 13 to complete the auxiliary collection process of the cell specimen preservation solution.
