Problems solved by technology

[0004] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide a quick and easy single cell picking device to solve the problem in the prior art that in the process of using a pipette to extract single cells, often due to the The poor contact of the extraction hose caused the hose to fall off during the extraction of the single-cell fluid, and because the connection between the pipette gun and the extraction hose was directly inserted and pressed together, it was easy to cause the connection It is uneven, which causes air leakage during the hose lifting process, which is not conducive to the picking of single cells.

Abstract

The invention discloses a quick, simple and convenient single cell picking device which structurally comprises a gun body, a display screen, a handle pad, a pressure adjusting key, an adjusting torsion bar, an extraction cavity column and a buckling assembly. The device has the beneficial effects that through the arrangement of the guide connection structure, the hose is connected in a guide manner under the action of the guide plate, so that when the hose is connected with the pipetting cavity, the hose is quickly and flatly connected, and the phenomenon that the hose is irregularly connected in a sleeving manner, then the single-cell liquid is separated when being extracted is avoided, and the connecting structure and the stroking and pressing mechanism are arranged in a matched manner, so that the connected hose is subjected to air bubble fitting and extrusion at the joint of the pipette and the hose under the stroking and matching of the wiping and pasting plate, and the phenomenon that the hose leaks air, and unnecessary factor influences are generated on single-cell extraction is avoided.

Description

technical field [0001] The invention relates to the field of experimental equipment, more specifically, a fast and simple single cell picking device. Background technique [0002] At present, the acquisition of single cells mainly relies on manual and automated methods. Manual picking is mainly carried out by means of mouth pipette, which requires the operator to use the mouth to cooperate with the pipette to pick out a single cell from the plate, which is cumbersome and has a certain risk of contamination; automatic picking requires large and expensive instruments and equipment, and there are high cost issue. [0003] In the process of using a pipette to extract single cells, often due to poor contact between the pipette and the extraction hose, the hose may fall off during the process of extracting the single-cell liquid, and due to the The connection with the extraction hose is directly interspersed and pressed together, which can easily lead to unevenness at the connec...
