Abstract

The invention provides a micro-fluidic chip, and belongs to the technical field of micro-fluidic control. The micro-fluidic chip comprises a chip substrate, the chip substrate is provided with a sample pool, a liquid output port and a liquid conveying pipeline communicated with the sample pool and the liquid output port. The sample pool is provided with an opening for injecting a liquid sample; afunctional pool is arranged on the liquid conveying pipeline in a communicating mode, and the liquid output port is externally connected with a negative pressure device so that negative pressure can be formed at the liquid output port. The liquid sample is transferred from the sample pool to the liquid output port so that the transfer operation of the liquid sample on the micro-fluidic chip is realized, and subsequent tests are facilitated.

Description

technical field [0001] The invention relates to the field of microfluidic technology, in particular to a microfluidic chip. Background technique [0002] The microfluidic analysis chip constructs various microfunctional components on the chip through microfabrication technology, thereby forming an analysis system with microfluidic control. Microfluidic chips have broad application prospects in many fields. Among them, biomedicine is currently the main application field of microfluidic chips. For example, microfluidic chips used for clinical testing have the most extensive market in my country. [0003] However, due to the small size and complex structure of the chip, the transfer operation of some liquid samples is prone to errors or cannot be realized, which leads to the failure of subsequent detection tests on liquid samples. Contents of the invention [0004] The purpose of the present invention is to provide a microfluidic chip, which can more accurately realize the ...
