Combined micro-fluidic chip

Abstract

The invention relates to the technical field of micro-fluidic chips. The invention provides a combined micro-fluidic chip. The chip comprises a disc-shaped chip body and an adapter, wherein the adapter is used for fixing the disc-shaped chip body on a detection instrument; the disc-shaped chip body is composed of a plurality of sectors, each sector is provided with a single chip body, each singlechip body is provided with a fixing structure matched with the adapter, a connecting structure matched with the single chip bodies in other sectors and a functional area used for reaction detection, and the front surface and the back surface of each single chip body are respectively provided with a packaging layer in the functional area. According to the combined micro-fluidic chip, the multiple single chip bodies can be freely combined and assembled into different types of joint inspection, the multiple single chip bodies can be assembled or the disc-shaped chip body can be disassembled easily through the connecting structure between the single chip bodies, and the adapter solves the problem of adaptation between the combined micro-fluidic chip and an existing detection instrument.

Description

technical field [0001] The invention relates to the technical field of microfluidic chips, and more specifically relates to a combined microfluidic chip. Background technique [0002] Microfluidic devices are usually called microfluidic chips, also known as lab-on-a-chip, which make the basic operation units involved in the fields of biology and chemistry, such as reaction, separation, cultivation, sorting, and detection, into micro / nano quantities. The micro-level components are integrated into a micron-scale chip, a network of micro-channels is formed, and controllable fluids are used to run through the entire system to achieve various functions of conventional biology or chemistry. [0003] The current disc-shaped microfluidic chip can only perform pre-embedded detection, and cannot flexibly configure joint detection types. For example, a disk-shaped 8-sample chip has a total of 8 sample chambers, each chamber has 4 reaction pools, and the detection reagents are pre-embe...

[0003] The current disk-shaped microfluidic chip can only perform pre-embedded detection, and cannot flexibly configure joint detection types

For example, a disk-shaped 8-sample chip has a total of 8 sample chambers, each chamber has 4 reaction pools, and the detection reagents are pre-embedded in the reaction pools, so the chip can detect 8 samples at the same time, and each sample Only 4 fixed inspection items can be jointly inspected, but the type of joint inspection cannot be changed by itself

In addition, when the number of measurable samples of the chip is greater than the number of samples to be detected, the redundant unreacted channels can only be wasted in the current disc-shaped microfluidic chip. Chips, often cause contamination due to poor storage or careless handling during reuse
