  • Method for continuously collecting fluorescence data of microfluidic chip
    Patent number: 11998909
    Abstract: A method for continuously collecting fluorescence data of a microfluidic chip is provided. In the method, an optical path system emits a light perpendicular to the microfluidic chip, such that a center of a light spot formed by the optical path system on the microfluidic chip is located on a circle formed by centers of all reaction cells. The microfluidic chip is rotated around a center of the circle formed by centers of all the reaction cells. Fluorescence signal values are collected by using the optical path system along a rotation direction of the microfluidic chip. The collected fluorescence signal values are processed to obtain effective fluorescence data of all the reaction cells.

  • Optical positioning code disk, device and method for microfluidic chip
    Patent number: 11975322
    Abstract: An optical positioning code disk, device and method for a microfluidic chip are provided. A cross section of an outer contour of the code disk is circular. N light transmissive openings are arranged uniformly around the code disk. The device includes: the code disk, a positioning pin, a rotating shaft, a motor, an internal photoelectric switch and an external photoelectric switch. A positioning surface is provided on the rotating shaft. The motor is fixedly connected with an end of the rotating shaft, and the other end of the rotating shaft passes through a center of the cross section of the code disk. The internal and external photoelectric switches are configured to identify the light transmissive openings on the code disk.
