Embodiment 1

[0028] Such as figure 1 , figure 2 As shown, a high-throughput multi-flow micropipette device includes a pipetting device and a liquid storage container, and the liquid pipetting device includes a mechanical arm 1 and an injection device; the liquid storage container is arranged on the mechanical arm 1 and passed through The position of the mechanical arm 1 is adjusted, and the liquid storage container is a multi-layer cavity structure with a plurality of independent liquid storage chambers 2, and each independent liquid storage chamber 2 is provided with a liquid inlet 3 and a multi-way needle 4, The liquid inlet 3 is connected to the injection device through the infusion tube 5, and the multi-way needle 4 is used for the liquid storage container to pick and place multiple liquids at the same time.

[0029] The liquid pipetting device first adjusts the multi-way needle 4 on the liquid storage container to a predetermined position through the mechanical arm 1, and then adjus...

Embodiment 2

[0031] On the basis of the foregoing embodiments, as a further preferred solution: as figure 1 , figure 2As shown, the liquid storage chambers 2 of the liquid storage container are arranged side by side and form an integrated structure, the number of liquid storage chambers 2 is not less than the number of syringes 7, and the infusion tube 5 is detachably connected to the injection port of the syringe 7 and Between the liquid inlet 3 of the liquid storage chamber 2. Multiple liquid storage chambers 2 are arranged side by side. Preferably, the side walls between multiple liquid storage chambers 2 are connected to each other, and the liquid inlets 3 are all arranged upwards; it is worth noting that since the syringe 7 can perform multiple liquid transfers , while the liquid storage chamber 2 generally can only store one kind of liquid at a time, and the number of syringes 7 is greater than the number of the liquid storage chambers 2, which can ensure that there is sufficient l...

Embodiment 3

[0033] On the basis of the foregoing embodiments, as a further preferred solution: as figure 1 , figure 2 As shown, the injection device is a multi-flow injection pump, including a PLC control system, a bracket 6 and at least two injection mechanisms, the injection mechanism includes a syringe 7, a servo motor 8, a lead screw 9 and a nut 10, and the PLC control system and The servo motor 8 is connected and controls the rotating speed of the servo motor 8. The lead screw 9 is connected with the servo motor 8 and rotates synchronously with the motor shaft. Linear movement, the syringe 7 is set on the support 6, the nut 10 pushes the piston of the syringe 7 to transport the liquid in the syringe 7 to the liquid storage container through the infusion tube 5 .

[0034] When working, the PLC control system sends out control pulses to rotate the servo motor 8, and the servo motor 8 drives the screw to convert the rotary motion into a linear motion, and pushes the piston of the syri...

Abstract

The invention provides a high-throughput multi-flow micro-pipetting device, which relates to the technical field of liquid pipetting equipment, including a liquid pipetting device and a liquid storage container, and the liquid pipetting device includes a mechanical arm and an injection device; the liquid storage container is set On the mechanical arm and adjust the position through the mechanical arm, the liquid storage container is a multi-layer cavity structure with multiple independent liquid storage chambers, and each independent liquid storage chamber is provided with a liquid inlet and a multi-way needle. , the liquid inlet is connected to the injection device through the infusion tube, and the multi-way needle is used for the liquid storage container to take and place multiple liquids at the same time. Compared with the traditional pipetting device, only one pipetting device is needed to realize the function of taking and placing multiple liquids separately. The liquids taken and placed have a separate liquid storage chamber for storage, which can effectively avoid contamination between samples, and The relative throughput is also increased, and it can be applied to the pipetting operation of multiple experiments at the same time.

Description

technical field [0001] The invention relates to the technical field of liquid pipetting equipment, in particular to a high-throughput multi-flow micro pipetting device. Background technique [0002] With the development of science and technology and the innovation of experimental technology, experiments in the fields of biochemistry and medical treatment involve more and more experimental equipment, and a large number of pipetting operations are required every day, such as mixing various liquid reagents and samples, Various volumes are accurately transferred to various analysis or testing equipment for various preparations and tests. [0003] The pipetting devices in the prior art are often pipette guns, generally row guns, whole-board combination guns or single-gun manual operations, which require multiple manual operations. When multiple samples exist, it is difficult to ensure the uniformity of processing between samples , the risk of contamination between samples is rel...
