As shown in fig. 1-2, the utility model relates to a high-precision medical electromagnetic infusion device, which comprises a medicine storage device 1, a micro-electromagnet 2, a shell and an injector 3;
the shell comprises a first shell 4 and a second shell 5, and the first shell 4 is arranged above the second shell 5; the second shell 5 is arranged above the injector 3, and the micro electromagnet 2 is arranged above the first shell 4; the medicine storage device 1 is arranged on one side of the first shell 4, the injection needle 6 is arranged on the other side of the first shell 4, and the medicine storage device 1 and the injection needle 6 are connected to the shell; an elastic rubber gasket 7 is arranged on the inner side of the first shell 4, and the middle of the elastic rubber gasket 7 is fixed on the first shell 4; permanent magnets 8 are arranged at two ends of one side of the elastic rubber gasket 7.
In this embodiment, the micro-electromagnet 2 includes a magnetic conductive block 2.1 and an electromagnet coil 2.2, and the electromagnet coil 2.2 is wound in the middle of the magnetic conductive block 2.1; a liquid inlet hole and a liquid outlet hole are arranged at the corresponding positions of the two ends of the first shell 4 and the magnetic conduction block 2.1, and an injection hole is arranged at the connecting position of the second shell 5 and the injector 3; more than one permanent magnet 8 corresponds to the liquid inlet hole and the liquid outlet hole on the first shell 4, and the liquid inlet and the liquid outlet of the liquid inlet hole and the liquid outlet hole are controlled by the adsorption of the permanent magnets 8 and the micro-electromagnet 2.
In the embodiment, a pipeline is arranged on one side of the medicine storage device 1, and the medicine storage device 1 is connected with a liquid inlet hole arranged on the first shell 4 through the pipeline; one end of the injection needle 6 is also provided with a pipeline, and the injection needle 6 is connected with the liquid outlet hole of the first shell 4 through the pipeline.

The working principle is as follows:
when the electromagnet is not electrified, the elastic rubber gasket naturally extends and is flatly laid on the inner surface of the shell, and the magnetic conduction block has no magnetism, so that the magnetic conduction block and the two ends of the permanent magnet are in a natural attraction state at the same time;
as shown in fig. 4, when the liquid medicine needs to be extracted, the electromagnet is powered on in the positive direction, and the magnetic conduction block gathers the magnetic field at the two ends of the magnetic conduction block and forms an N pole and an S pole; the permanent magnet moves inwards due to the fact that magnetism repels liquid inlet holes of the medicine storage device pipeline, the rubber gasket is bent under the driving of the permanent magnet, and therefore the medicine storage device pipeline is opened, and the liquid inlet holes of the medicine storage device are in an open state; meanwhile, the injection pipeline is in a closed state due to the fact that the injection pipeline is magnetically attracted, the rubber gasket is in a close fit mode under the strong attraction effect of the permanent magnet, and liquid medicine flows into the injector under the action of negative pressure in the valve;
as shown in fig. 5, when the liquid medicine needs to be injected, the electromagnet is energized in the reverse direction, the magnetic conduction block gathers the magnetic field at the two ends of the magnetic conduction block and forms an S pole and an N pole, and the polarity is opposite to that of the liquid medicine extracting operation. At the moment, the liquid inlet hole of the medicine storage pipeline is closed due to magnetic attraction, and the liquid outlet hole of the injection pipeline is opened due to magnetic repulsion.
The above description is only an embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that are not thought of through the inventive work should be included in the scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope defined by the claims.
