Abstract

The invention discloses a multi-channel automatic pipetting gun, which solves the problems of automatic sampling and sample loading and improves the efficiency, wherein the sample loading and the sample discharging of each channel can be completely consistent and synchronous. The multi-channel automatic pipetting gun comprises a driving assembly, a piston assembly and a piston sleeve gun head assembly, wherein the piston assembly can movably arranged in a shell in an up and down direction, and comprises a sliding plate slidably connected to the shell in an up and down manner, and a plurality of pistons arranged on the sliding plate and capable of extending up and down, the piston sleeve gun head assembly is arranged on the lower end portion of the shell, and comprises a plurality of pipetting units, each pipetting unit comprises a piston sleeve positioned in the shell, a gun head seat arranged on the lower end portion of the shell, and a gun head positioned outside the shell and used for loading tips, the piston sleeve and the gun head are respectively arranged on the gun head seat, each gun head and the corresponding piston sleeve form a cavity, the piston can be inserted into thecavity, and moves up and down in the cavity, and the gun head is provided with through holes for communicating the cavity and the inner cavity of the tip.

Description

technical field [0001] The invention relates to the field of medical detection and analysis equipment, in particular to a multi-channel automatic pipetting gun. Background technique [0002] The pipette gun is a commonly used test tool in biological experiments, and is often used for taking and pipetting a small amount or a small amount of liquid. The existing lance structure for pipetting cannot ensure that the liquids of all channels are delivered synchronously during the liquid supply process of the lances, and the quality cannot be guaranteed. For example, Chinese patent CN208975834U discloses a pipette gun, comprising: a first cavity and a second cavity connected to each other, the first cavity is provided with a first cavity, and the second cavity is provided with a second cavity. cavity, the first cavity communicates with the second cavity; the second cavity includes a plurality of the second cavities arranged at intervals, and each of the second cavities The end of...
