Sample injection module used for micro-fluidic chip and NC membrane multi-throughput detection

Abstract

The invention discloses a sample injection module, which is provided with a chip sample injection card slot and a NC membrane sample injection card slot that are independent of each other and are respectively used for inserting a chip or a NC membrane card; the sample injection module is also provided with a liquid path-gas path module; a chip sample injection shifter is arranged on the side surface of the chip sample injection card slot and is fixedly connected to a first driving connection piece which moves forth-and-back through synchronous belt driving by a power motor of the chip sample injection shifter; an NC membrane sample injection shifter is arranged on the side surface of the NC membrane sample injection card slot and is fixedly connected to a second driving connection piece which moves forth-and-back through synchronous belt driving by a power motor of the NC membrane sample injection shifter; the liquid path-gas path module in the sample injection module is used for ensuring that a chip reaction cavity is fully filled with a sample and a reagent for reactions. The sample injection module satisfies technical application scenes of both micro-fluidic chip and NC membranedetections, and can complete simultaneously sample injection of the two test platforms, micro-fluidic chip and NC membrane.

Description

technical field [0001] The invention belongs to the technical field of medical equipment, and in particular relates to a sampling module for multi-flux detection of microfluidic chips and NC membranes. Background technique [0002] Microfluidic chip (microfluidic chip) is currently a hot field in the development of Miniaturized Total Analysis Systems.
