Abstract

The invention discloses a uniform liquid mixing device applied to microfluidics. The device comprises: a body, wherein a liquid flow system is arranged in the body, and comprises a solution cavity for loading a liquid to be subjected to uniform mixing and a buffer cavity communicated with the solution cavity; and a power mechanism used for periodically generating positive air pressure and negative air pressure for the liquid flow system to form power for pushing the liquid to be subjected to uniform mixing, so that the liquid to be subjected to uniform mixing flows between the solution cavity and the buffer cavity in a reciprocating manner. The invention also discloses a microfluidic chip, which comprises the uniform liquid mixing device applied to microfluidic control disclosed by the invention. According to the invention, the technical problems that a traditional uniform mixing tool is large in occupied space, complex in operation and prone to leakage are at least solved.

Description

technical field [0001] The invention relates to the technical field of liquid mixing. More specifically, the present invention relates to a liquid mixing device and a microfluidic chip applied to microfluidics. Background technique [0002] In in vitro diagnostic testing, it is necessary to mix multiple fluids to achieve the detection task. The traditional mixing methods mainly include the following: 1) Add the liquid sample and diluent into the beaker, and stir and mix with a glass rod; 2) Use two beakers to invert the liquid back and forth to mix the liquid; 3) Use a single beaker to and fro Shake to mix. The above-mentioned mixing methods have the following unavoidable defects: 1) The mixing tools (such as the aforementioned beakers and glass rods) take up a lot of space; 2) There are too many mixing tools and the operation process is complicated; 3) Leakage is prone to occur, pollute the environment. Contents of the invention [0003] It is an object of the present...
