Title:
LIQUID PATH SYSTEM FOR GENE SEQUENCING
Document Type and Number:
WIPO Patent Application WO/2023/108962
Kind Code:
A1
Abstract:
A liquid path system for gene sequencing, comprising a rotary valve (1), an electromagnetic valve (2), a reaction device (3), an injection pump (4) and a waste liquid collection device (5). The rotary valve (1) is provided with a plurality of reagent input channels (10) communicated with a kit and a reagent output channel (11). The electromagnetic valve (2) is a three-way electromagnetic valve provided with a first channel (20), a second channel (21) and a third channel (22). The reaction device (3) is provided with a fourth channel (30) and a fifth channel (31). The injection pump (4) is provided with a first injection pump channel (40) and a second injection pump channel (41). The first channel (20) is communicated with the reagent output channel (11) by means of a second conduit (200), and the second channel (21) is communicated with the fourth channel (30) by means of a third conduit (210). The third channel (22) is communicated with the first injection pump channel (40) by means of a fourth conduit (220), the fifth channel (31) and the second injection pump channel (41) are correspondingly connected to a fifth conduit (310) and a sixth conduit (410), and both the fifth conduit (310) and the sixth conduit (410) are in non-sealed communication with the waste liquid collection device (5). The system is more stable, and avoids fluctuations when taking pictures, so that the pictures are clearer.
