Abstract

The invention discloses a sampling device, which comprises a shell, wherein a drive assembly, a drill pin assembly and a discharge assembly are arranged in the shell; the drill pin assembly comprisesa drill pin and a drill pin mounting shaft; the drill pin mounting shaft is connected with the drive assembly and can drive the drill pin to rotate under the drive of the drive assembly; the dischargeassembly comprises a knob and a discharge screw rod; the discharge screw rod is connected with the drill pin assembly; the knob is connected with the discharge screw rod and can drive the discharge screw rod to rotate to discharge materials; and an experimenter operates the sampling device with one hand, clamps a to-be-sampled mother sample on a special freezing table, clamps a special limiting sleeve on a sampling test tube, starts a button and presses the sampling device to carry out sampling work. The sampling work is completed when the sampling quantity meets the original set quantity, and the sampled sample is spun out into a target container. The frozen sample is quantitatively taken out in a targeted manner on the premise of keeping the mother sample in a non-frozen-thawed state, and the original tissue property of an experimental sample is kept to the maximum extent.

Description

Technical field

[0001] The invention relates to the field of sampling devices, in particular to a sampling device. Background technique

[0002] At the current stage, the biological sample library adopts relatively simple and primitive methods for sampling various types of frozen samples. In a frozen state such as -196° or -80°, biological samples will become extremely hard. If some samples need to be taken out for experiments, usually the researcher will freeze and thaw the mother samples, and then knock the mother samples with the tip of tweezers or a knife Surface, make the surface cracks and even a small sample block collapse, pick out the small sample block into the target container for the next scientific research experiment.

[0003] However, repeated freezing and thawing can cause a great loss of RNA in biological samples. Some brain tissue proteins may be lost or degraded after freezing and thawing, which will directly affect the results of medical research. Some samples...
