Abstract

The invention discloses a reagent continuous quantitative injection device. The device comprises a power mechanism, at least one injection syringe and a support connection mechanism. The support connection mechanism comprises an upper fixing plate, a lower fixing plate and an adapter plate. The power mechanism comprises a motor and a power output shaft. The injection syringe comprises a syringe needle, a syringe cylinder, a piston rod and a piston fixed to the end of the piston rod. The upper fixing plate is fixed above a microfluidic chip by a support rod. The lower fixing plate is located below the upper fixing plate and is fixedly connected to the upper fixing plate by a connection rod. The device utilizes the power mechanism and the at least one injection syringe. The power mechanism is controlled by an upper computer and drives the injection syringe so that an injection process is finished. The device realizes continuous automatic injection. The power mechanism can synchronously drive one or more syringes so that injection efficiency is further improved.

Description

technical field [0001] The invention relates to an injection device, in particular to a reagent continuous quantitative injection device. Background technique [0002] Microfluidic technology is based on micro-electromechanical processing (MEMS) technology. The chip integrates micro-functional modules such as micro-channels, micro-electrodes, micro-pumps, micro-valves, micro-storage tanks, micro-detection modules and connectors into the chip through maintenance processing. Micro-total analysis system on materials. Compared with conventional chemical and biological analyzers, microfluidic chips are more efficient and quicker, save reagents and costs, and have high integration and high precision. applications have developed rapidly. [0003] The quantitative injection operation of microfluidics is the core of microfluidic chip analysis technology, and it is the premise of microfluidic chip to achieve reagent ratio mixing. So far, there is no specific injection technology f...
