The utility model discloses an auxiliary sample
liquid transfer device for a medical 96-well plate. Comprising a main
machine body, a loading plate, a travel switch, an orthogonal moving unit, a pipetting
execution unit and a needle replacement unit, a
disposable needle head is preassembled in the needle head replacing unit and is a capillary
glass tube, and a needle
handle is arranged at the top of the
disposable needle head. Through effective combination of the orthogonal moving unit and the pipetting
execution unit, automatic transfer of sample liquid in an EP tube plate and a 96-well plate is realized, meanwhile, automatic replacement of a needle head can be realized by virtue of the needle head replacement unit, and a needle head
recovery chamber is additionally arranged, so that the
pollution problem caused by disordered placement of the needle head is prevented; the full-
process operation of manually transferring the sample liquid, replacing the
disposable needle head and abandoning the needle is simulated to a great extent, the manual labor force is liberated by an automatic method, the
technical risk of sample
liquid transfer dislocation is also prevented, and the accuracy and the working efficiency are improved.
