Sample loading device and sample driving device

Abstract

The invention discloses a sample loading device and a sample driving device. The sample loading device includes a sample fixing module, a test tube module and a loading tale, wherein a stepped throughhole is formed in the middle of the loading table; a first annular boss and a second annular boss are arranged inside the stepped through hole; the sample fixing module includes a circular panel anda straight rod; the test tube module is magnetically buckled onto the upper surface of the second annular boss; the panel of the sample fixing module is magnetically buckled onto the upper surface ofthe first annular boss; the straight rod can be inserted inside the test tube module. According to the invention, mounting and connection between the test tube module and the loading table and betweenthe sample fixing module and the loading module is realized through the magnetic attraction; during application of the device, operation convenience and accuracy are improved, and the measurement accuracy is improved; the sample driving device can be used for mounting a sample to be tested onto a rotary component through the sample loading device, so that the operation convenience of the device during application is improved, and the measurement accuracy of tomography is improved.

Description

technical field [0001] The present invention relates to the technical field of optical projection tomography devices, and more specifically relates to a sample loading device and a sample driving device applied to an optical projection tomography system. Background technique [0002] Optical projection tomography is a new type of three-dimensional imaging technology for small biological specimens. This three-dimensional imaging technology uses optical cleaning agents to clean or use transparent samples, and uses ultraviolet, visible and near-infrared spectra to transmit through samples. photons to compute three-dimensional structures. [0003] At present, the sample loading scheme of the optical projection tomography system mainly uses a perforated rubber plug to pass the sample fixing device through the through hole on the rubber plug. The sample fixing device is fixed with the sample to be tested, and finally the rubber plug is inserted into the At the end of the test tub...

Problems solved by technology

[0004] The advantage of the existing sample loading scheme is that the required loading components are simple and low in cost, but the disadvantage is that the rubber stopper is easily aged due to the influence of the environment or the number of uses, resulting in deformation of the through hole of the rubber stopper, which easily makes the sample to be tested inside the test tube Offset from the center position, and after inserting the rubber stopper into the test tube port, the rubber stopper will be more or less inclined to a certain extent, which will also easily make the test sample inside the test tube deviate from the center position, and the test tube will be tested during the rotation of the test tube. The sample is easy to leave the depth of field range, which affects the accuracy of the projection data
