AI Technical Summary

Technical Problem

The existing portable biochemical analyzers have a long operating time when adding diluents, resulting in lower detection efficiency.

Method used

A portable biochemical analyzer is designed, including a liquid storage container, a liquid injection device and a clamping device. The liquid storage container pushes the piston part through the liquid injection device, and the piston part squeezes the diluent to make it flow out of the liquid outlet tube, which has a high liquid injection accuracy. The clamping device clamps the tube body to ensure that the tube body is stable when the piston moves and the position is accurate when the diluent is injected.

Benefits of technology

By improving the injection accuracy and shortening the dilution addition time, the biochemical detection efficiency is significantly improved. The design of the clamping device ensures stability and accuracy of operation.

Abstract

The invention provides a portable biochemical analyzer. The portable biochemical analyzer comprises a shell, a liquid storage container, a liquid injection device and a clamping device, the liquid storage container is vertically inserted into the machine shell and comprises a pipe body and a piston part, the pipe body is used for containing diluent, and a liquid outlet pipe directly facing a freeze-drying reagent on the microfluidic disc is arranged at the bottom end of the pipe body; one end of the piston part is slidably arranged in the tube body, and the other end extends out of the tube body; the liquid injection device is arranged in the machine shell and provided with a power end capable of moving in the axial direction of the pipe body, and the power end is detachably connected with the end, extending out of the pipe body, of the piston part so as to extrude diluent. The clamping device is arranged in the machine shell and used for clamping the pipe body in the circumferential direction of the pipe body. The portable biochemical analyzer disclosed by the invention has relatively high diluent injection precision and a good dilution effect on a freeze-drying reagent; different freeze-drying reagents on the micro-fluidic disc are added with diluents without repeated displacement operation, so that the biochemical detection efficiency is high; the clamping device clamps the pipe body, so that the pipe body is more stable and not prone to shaking.
