Abstract

The invention discloses an automatic suction device. The automatic suction device comprises a rack, a pipetting gun, a first driving mechanism, a second driving mechanism and a control system, wherein the pipetting gun is fixedly arranged on the rack, a button is arranged on the pipetting gun, and the button has a first function of changing a pipetting range through rotation and also has a second function of sucking and discharging liquid through translation; the first driving mechanism is arranged on the rack in a sliding mode, the first driving mechanism is fixedly connected with the button, and the first driving mechanism is used for driving the button to rotate; the second driving mechanism is arranged on the rack and is used for driving the first driving mechanism and the button to synchronously translate; and the control system is used for respectively controlling the first driving mechanism and the second driving mechanism. The pipetting gun is fixed on the rack, the volume of sucked liquid is controllable by rotating the button through the first driving mechanism, the liquid is sucked and discharged by pressing the button through the second driving mechanism, the volume of pretreatment is adjusted through the control system, and related pipetting operation is carried out, so that automatic and accurate pipetting is realized, and the cost of the pipettor is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to an automatic suction device. Background technique [0002] Pipettes are often used for pipetting a small amount or micro-volume of liquid in the laboratory. For pipette guns, all pipetting needs to be operated manually, and automatic liquid extraction cannot be realized. The operation is not accurate enough, and it is not convenient enough. Contents of the invention [0003] The purpose of the present invention is to solve at least one of the technical problems in the prior art, and to provide an automatic suction device capable of performing pipetting operations with high precision. [0004] According to an embodiment of the first aspect of the present invention, an automatic suction device is provided, comprising: [0005] frame; [0006] The pipette gun is fixedly arranged on the frame, the pipette gun is provided with a button, and the button has the first fun...
