Abstract

The invention provides a waste liquid sucking and collecting device which is used for sucking and collecting waste liquid generated in cytological experiments and the like. The waste liquid sucking and collecting device comprises a suction head used for sucking waste liquid, a liquid suction pump which is used for providing power for suction of the waste liquid and is provided with a pedal type control switch used for controlling starting and pausing of the liquid suction pump, a waste liquid collecting container which is connected with the suction head and is used for collecting the waste liquid sucked by the suction head, a suck-back prevention pipe which is connected between the suction head and the liquid suction pump, and a hanger to which the suction head can be fixed. By applying the waste liquid sucking and collecting device provided by the invention, cell pollution caused by suck-back of the waste liquid can be reduced, noise pollution generated by a negative pressure liquid sucking pump is effectively improved, energy is saved, the environment is protected, and instruments are protected. Moreover, through the suction head and the hanger matched with the suction head, the experiment operation can be facilitated, the operation space of a biosafety cabinet is reasonably utilized, and the pollution probability in the experiment process is reduced.

Description

technical field [0001] The invention belongs to the field of biomedical scientific research experimental equipment, and in particular relates to a set of waste liquid suction and collection devices suitable for suction and collection of waste liquid generated in cytology experiments and the like. Background technique [0002] In biomedical experiments, cytology experiments are one of the basic, common and important experimental techniques. Among them, the suction and addition of culture medium, buffer solution, drug or other reagent waste liquid are the basic operations of cytology experiments. This operation is to suck the above-mentioned liquid from the culture vessel or centrifuge tube, and then add new liquid, and must maintain strict sterility during the whole operation. Most laboratories suck up the above-mentioned waste liquid by manually sucking it with a micropipette or a straw, and then discharge the waste liquid into a small waste liquid bucket, and dump it after...
