Automatic micro-injection device and control method thereof

Abstract

The invention provides an automatic micro-injection device which comprises a supporting plate which is vertically arranged; a supporting frame which is vertically arranged on the supporting plate andcan move in the axial direction of the supporting plate; a horizontal guide rail which is horizontally and vertically arranged on the supporting frame in a sliding manner; a connecting frame which isarranged on the horizontal guide rail in a sliding manner; an injection frame which is rotatably arranged on the connecting frame; an injection arm which is rotatably arranged on the injection frame;a puncture power mechanism which is fixedly arranged on the injection arm; a puncture frame which is fixedly arranged at the output end of the puncture power mechanism; an injection needle clamping device which is fixedly arranged at one axial end, far away from the puncture power mechanism, of the puncture frame; an injection power mechanism which is fixedly arranged at the other axial end of thepuncture frame; and a pushing plate which is fixedly arranged at the output end of the injection power mechanism and is used for being matched with a pushing rod of an injection needle and driving the pushing rod to push for administration. The invention further provides a control method of the automatic micro-injection device.

Description

technical field [0001] The invention relates to the technical field of micro-injection of liquid medicine, and more specifically, the invention relates to an automatic micro-injection device and a control method thereof. Background technique [0002] In animal experiments, tail vein drug injection is often required, which is basically done manually by the test personnel, and when the drug is injected, the animal is likely to struggle or muscle shaking, resulting in easy needle shaking, deviation or even needle failure during injection. Disengaging and accidentally injuring the test personnel also increases the difficulty of operation. [0003] Chinese invention patent 201310342063.6 discloses an intelligent veterinary syringe, which is specifically composed of an environmental protection device, an intelligent controller, a liquid medicine booster, an automatic infusion device, a sensor, a telescopic rod and continuous syringes of different specifications. When giving an in...

But it also needs to manually determine the injection point and perform needle injection

[0005] Therefore, when injecting medicinal liquid in animal experiments, the experimenter basically determines the injection point based on experience and manually injects the needle, resulting in a great relationship between the success rate of an injection and the experience of the experimenter, which also causes the success rate of an injection to vary. together

Not only reduces the efficiency of animal experiments, but also increases animal suffering
