AI Technical Summary

Technical Problem

The prior art is difficult to maintain the stability of the magnetic field strength and gradient when transmitting magnetic fields from a distance, resulting in insufficient accuracy when introducing magnetic labeled cells and biological macromolecules in specific parts of the body or object.

Method used

A magnetic guide device is designed, including an outer cladding, a plurality of magnetic bodies and a probe. The magnetic bodies are arranged in sequence along the axial direction of the outer cladding layer, and form a chain structure through opposite-sex attracting connections, so that the magnetic inductive lines are continuously superimposed along the axial direction, maintaining a strong and stable magnetic field strength.

Benefits of technology

It achieves long-distance targeted transmission of magnetic fields without significant attenuation, ensuring the strength and direction of the magnetic field in specific parts of the body or object, and thus improving the precise enrichment effect of magnetic labeled cells and biological macromolecules.

Abstract

The present invention provides a magnetic guide device, including an outer layer, a plurality of magnetic bodies and a probe. The outer layer is in the shape of a hollow cylinder; the outer layer is made of sterile biological material, and the outer layer is flexible and can be bent along its axial direction; a plurality of magnetic bodies are arranged in sequence in the outer layer along the axial direction of the outer layer; each magnetic body has magnetism, and the polarity of the two ends of the magnetic body along the axial direction of the outer layer is different, and the polarity of the adjacent ends between any two adjacent magnetic bodies is different and attracts each other; the probe and the magnetic body are located at one end of the axial direction of the outer layer through magnetic attraction, and can adsorb magnetically labeled cells, biological macromolecules or other substances with paramagnetism or permanent magnetism. The magnetic flux lines of the magnetic guide device are continuously superimposed along its axial direction, so that the magnetic field strength can be kept strong and stable along the axial direction, and the magnetic field strength in other directions except the axial direction is significantly weakened, that is, the magnetic guide device realizes long-distance targeted transmission of magnetic field without obvious attenuation through multiple magnetic bodies.
