Abstract: A nucleic acid detection kit includes a detection chip, an electrophoresis box, and a barrier unit. The detection chip includes a channel and an outlet. The outlet is connected to the channel. The temperature-dependent barrier unit may be in a first state or a second state. The barrier unit is disposed on a side of the outlet close to the channel when the barrier unit is in the first state, so that the channel is disconnected from the electrophoresis box. The barrier unit is away from the outlet when the barrier unit is in the second state, so that the channel is connected to the electrophoresis box. A nucleic acid detection device including the nucleic acid detection kit is also disclosed. The nucleic acid detection device has a simple structure, which is portable, flexible, and convenient, and can be used at home.

Abstract: A device for transferring liquids and liquid samples in certain quantities includes a pressing unit and a liquid extraction assembly. The pressing unit includes a first housing and a second housing. The first housing includes a first sidewall, a first top wall, and an extrusion portion. The second housing includes a second sidewall, a second top wall, and a receiving cavity. The first housing is received in the receiving cavity. The liquid extraction assembly includes a liquid extraction pipe, a liquid extraction head, and a first connecting portion. The first housing is configured to move back and forth along the receiving cavity to drive the extrusion portion to compress and deform the liquid extraction pipe. The liquid extraction assembly is detachably installed in pressing unit and is replaceable and suitable for single-use situations.

The second housing includes a second sidewall, a second top wall, and a second receiving cavity. The first housing is received in the second receiving cavity. The liquid extraction assembly includes a liquid extraction pipe and a liquid extraction head. By thumb or finger pressure, the first housing can be moved into the second receiving cavity to compress the extrusion portion to cause release of a sample, or released to gather a sample.
