Embodiment Construction

[0045] In the following description, for the sake of clarity, a three-dimensional coordinate system is established, where the X direction refers to the length direction (injection direction) of the syringe pump, the Z direction refers to the height direction (up and down direction) of the syringe pump, and the Y direction refers to the Refers to the width direction (left and right direction) of the syringe pump.

[0046] refer to figure 1 , the syringe pump in the prior art generally uses two guide rails, and the two guide rails (or called guide rods) or push rods 1 and 2 are arranged in parallel in the same plane, and the driving mechanism 4 used to push the syringe handle receives the wire The driving of the rod 3 moves along the X direction, and generally in consideration of reducing the size, the distance between the lead screw 3 and the plane where the two guide rails 1 and 2 are located in the Z direction is not very large. After the syringe (not shown) is clamped on th...

Abstract

The invention provides an injection pump. The injection pump comprises a base, a motor, an injector tube pressing block, three X-axis parallel guide rods, a lead screw and an injector handle assembling mechanism, wherein the motor, the injector tube pressing block and the three X-axis parallel guide rods are installed on the base, the lead screw is driven by the motor, the injector handle assembling mechanism is provided with three guide holes, an injector handle limiting groove and a drive hole, the lead screw is matched with the drive hole to form a lead screw pair, and the guide rods are matched with the guide holes to form a sliding pair; the centers of the three guide holes are located on three vertexes of an equilateral triangle, the center of the drive hole is located in the center of the equilateral triangle, and the symmetrical axis of the injector handle limiting groove coincides with the Z-axis center line of the equilateral triangle. The invention further provides an injection system and an injection method through which the parallel control can be achieved. The injection pump, the injection system and the injection method have the advantages of being high in injection precision and high in universality.

Description

technical field [0001] The invention relates to the field of injection of chemical materials, in particular to an injection device, an injection system and an injection method of fluid chemicals in chemical experiments. Background technique [0002] As microfluidic chips are widely used in various chemical experiments and tests in recent years, in one experiment, the injection rate and sequence of injection of multiple drugs may be required, and sometimes several drugs must be realized during the experiment. Simultaneous injection in different proportions. Therefore, the performance requirements of the injection system are becoming more and more stringent. It is required that they can inject accurately according to the set injection rate, and it is also required that the operator can easily set up the cooperative work of each pump. [0003] At present, although there are some syringe pump systems at home and abroad, most of their design of the circuit control unit is centere...
