Description

Technical Field

[0001] The utility model relates to the technical field of microchannel chips, in particular to a microchannel chip degumming device. Background Art

[0002] The benefits of miniaturization for biochemical experiments include accurate quantification, saving on the number of specimens, and easy observation and automation of multiple reactions at one time. As miniaturization technology becomes more mature, many traditional culture dishes are gradually replaced by chips, and cells are cultured on chips with microfluidics to study the drug stimulation response of single cells. Generally speaking, cells are cultured in the microfluidics of the chip, and liquid containing drugs is injected. When the liquid flows, the drugs contained in the liquid will react with the cells to study the stimulation of the drugs on the cells. In order to prevent the drug from diffusing in the microfluidics and affecting the correctness of the drug's action time on the cells, the drug is usually wrapped with bubbles and then delivered during the experiment to accurately control the drug's stimulation time on the cells.

[0003] The patent with publication number CN 115648033 A discloses a chip degumming device and a degumming method, wherein the device comprises a grinder, a base plate, a rotating platform and a clamping linkage mechanism for clamping the chip, wherein the grinder is mounted on one end of the upper surface of the base plate, the rotating platform is slidably arranged on the other end of the upper surface of the base plate, the clamping linkage mechanism is arranged on the rotating platform and can rotate with the rotating platform, and the clamping linkage mechanism can slide on the base plate with the rotating platform to approach or move away from the grinder, and the grinder can grind the glue remaining on the edge of the chip clamped on the clamping linkage mechanism.

[0004] The above-mentioned device uses a grinder to grind the glue on the chip. Although this method can remove the glue on the chip, it may cause damage to the chip during the grinding process. For semiconductor chips, grinding with a grinder can indeed achieve the purpose of removing the glue, but for microfluidic chips, removing the glue by a grinder is very likely to cause damage to the chip. For microfluidic chips, heating the degumming medium to soften the degumming is less likely to damage the chip itself than semiconductor chips. Utility Model Content
