Abstract

The invention relates to a blood type detection device based on microfluidic chips and STM32. The device comprises a base, an eccentric device and a positioning device. A switch and a touch screen are arranged at the right front end of the base. The eccentric device comprises an eccentric rotating disc and a direct-current brushless motor. The direct-current brushless motor is installed in the middle of the base and is connected with a rotating disc connecting shaft, the rotating disc connecting shaft sequentially penetrates upwards through an upper partition plate and a rubber pad and is connected with the eccentric rotating disc, and an inner ring and an outer ring of 24 clamping grooves used for containing the microfluidic chips are formed in the eccentric rotating disc. According to the device, an STM32 controller serves as a core, and positioning and eccentric operation are completed through the two crossed ball screws on the upper portion and a working table. With the combination of an embedding type, the microfluidic technology, movement control, optical detection and other technologies, the blood type detection device has the advantages of being accurate in positioning, high in speed and efficiency, intelligent, flexible, convenient to use and the like.

Description

technical field [0001] The invention relates to the technical field of blood detection in medicine, more specifically to a blood type detection device developed based on a microfluidic chip and STM32 embedded. Background technique [0002] Blood testing is a common testing content in medicine, such as testing blood type, red blood cell count, blood sugar, hemoglobin concentration, etc. The miniaturization and miniaturization of blood testing instruments is the future trend. There are already small blood glucose testing instruments on the market, but there is no small blood type testing equipment. Because the traditional micro-column gel blood type card is mostly used for blood type detection at present, and the controller of the blood centrifuge is relatively large, resulting in problems such as poor portability of the whole machine and low detection efficiency. [0003] Microfluidic chip is an emerging technology industry. With its advantages of miniaturization and high th...
