摘要： A liquid transfer device includes a transfer unit, a reaction chamber, and a collecting unit. The collecting unit receives a sample solution. The transfer unit includes a piston assembly, a pipette, and a reagent adding unit, a portion of the piston assembly is received in the pipette. The piston assembly moves back and forth along the pipette and the reagent adding unit can receive a reagent. In a first state, the transfer unit is disposed above the collecting unit. In moving away from the collecting unit, the piston deforms the pipe to intake a sample. In a second state, the piston assembly can move closer to the reaction chamber to deform the pipe and release the reacted sample.

摘要： A nucleic acid detection host includes a host body, a detection kit installation area, a sample heating area, a sampling groove, a heating structure, and an image collection unit. The detection kit installation area is configured to detachably install a nucleic acid detection kit. The sampling groove is disposed on the detection kit installation area and is connected to the detection kit installation area. The heating structure is configured to heat the nucleic acid detection kit to perform a PCR amplification reaction and an electrophoretic detection. The image collection unit is configured to collect an image of the nucleic acid detection kit. A nucleic acid detection device including the nucleic acid detection host is also disclosed. The nucleic acid detection device has a simple structure, which is portable, flexible, and convenient, and can be used at home.
