Detection system and micro-fluidic chip clamp therefor

Abstract

The invention relates to a detection system and a micro-fluidic chip clamp therefor. The micro-fluidic chip clamp comprises a base, two turning covers which are both rotationally connected with the base and matched with the base to form clamping spaces, and a fastening mechanism for fixing the turning covers on the base, wherein a chip groove for placing a micro-fluidic chip is formed in the base; the chip groove is connected with the two clamping spaces; one end, equipped with a liquid inlet, of the micro-fluidic chip extends into one clamping space while one end, equipped with a liquid outlet, of the micro-fluidic chip extends into the other clamping space; and the micro-fluidic chip is clamped between the two turning covers. When the micro-fluidic chip is installed, the fastening mechanism is opened, and the turning covers are turned up, and then the micro-fluidic chip is placed in the chip groove, the turning coves are closed, and the fastening mechanism is tightly locked; and when the micro-fluidic chip needs to be replaced, the fastening mechanism is opened, the turning coves are turned up, the original micro-fluidic chip is taken out and a new micro-fluidic chip is placed into the chip groove, so that the replacement of the micro-fluidic chip is quite convenient, and the detection efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, in particular to a detection system and a microfluidic chip fixture thereof. Background technique [0002] The digital PCR (Polymerase chain reaction) detection device requires high detection accuracy and needs to be able to accurately detect the size of the fluorescent signal contained in each liquid droplet passing through the detection flow channel. Evenly spaced. Since the microfluidic chip used for digital PCR detection devices generally only arranges the diluent, when the droplet size is smaller than the channel size of the chip, the arrangement effect is poor, so the chip is often replaced due to the change of the droplet size. When the microfluidic chip is installed, it needs to be connected with the external pump valve system and pipeline. At present, the microfluidic chip and the pipeline are connected by pins, glue, etc., but these connection methods are irreversible and ca...

Since the microfluidic chip used for digital PCR detection devices generally only arranges the diluent, when the droplet size is smaller than the channel size of the chip, the arrangement effect is poor, so the chip is often replaced due to the change of the droplet size

When the microfluidic chip is installed, it needs to be connected with the external pump valve system and pipeline. At present, the microfluidic chip and the pipeline are connected by pins, glue, etc., but these connection methods are irreversible and cannot be connected to the chip. Replacement; there is also a connection method to fix the microfluidic chip through a fixture, but when replacing the chip, all the fixture parts need to be dismantled, which is inconvenient for chip installation and disassembly, inconvenient to use, and reduces detection efficiency
