Multi-channel incubation device and sample preparation equipment that can support chip tilt

Abstract

The invention discloses a multi-channel incubation device capable of supporting chip inclination, which comprises a plurality of incubation components, each incubation component includes: a bracket; For the platform on which the microfluidic chip is placed and the electric heating element for heating the microfluidic chip, the axial direction of the rotating shaft is perpendicular to the direction from the first end to the second end of the platform, and parallel to the plane where the platform is located, and the rotating shaft is connected The position on the rotating block away from the first end; the drive assembly that drives the rotating block to rotate along the rotating shaft; the extrusion part on the bracket, the extrusion part is located on the rotation path of the first end of the platform, and the rotating block rotates from the horizontal position to In the first position, the platform is in an inclined state where the first end is higher than the second end, and the extrusion member can abut against the cleaning liquid bubble of the microfluidic chip and break the cleaning liquid bubble. The device can synchronously inject cleaning liquid and can control the flow speed of the liquid in the microfluidic chip.

Description

technical field [0001] The present invention relates to the technical field of biological detection, and more particularly, to a multi-channel incubation device that can support chip tilt and a sample preparation device including the multi-channel incubation device that can support chip tilt. Background technique [0002] In the prior art, a microfluidic chip applied to immunodetection analysis refers to setting a microfluidic channel structure and other functional elements (such as a cleaning liquid bubble wrapped with a cleaning solution) on the chip, adding a sample into the microfluidic channel, and testing the microfluidic chip. The sample flows in the microfluidic channel, and an immune reaction occurs during the flow to generate conjugates. The conjugates can be adsorbed in a certain area (adsorption area) in the microfluidic channel, and then the cleaning vacuole at the beginning of the microfluidic channel is punctured to make The cleaning solution is injected into ...

AI Technical Summary

Problems solved by technology

However, tilting requires manual lifting or adding supports, and the number of microfluidic chips is large, all manual lifting is time-consuming and laborious, and it is difficult to control the tilting angle by adding supports; and piercing each cleaning bubble one by one. The operation of injecting the cleaning solution into the flow channel is cumbersome and requires a long time of manual operation, which also leads to a difference in the time of adding the cleaning solution to each microfluidic chip.

[0004] Therefore, it is urgent to solve the problems of cumbersome injection of cleaning solution into each microfluidic chip, asynchronous injection time and slow flow of samples and cleaning solution in the microfluidic chip, requiring operators to wait for a long time and check regularly
