A device for guiding the lattice distribution of magnetic induction intensity

Abstract

The invention discloses a device for guiding lattice distribution of magnetic induction intensity. The device comprises a permanent magnet and a plurality of soft magnetic wires arranged in an array mounted on the surface of the permanent magnet by a fixing module; a plurality of soft magnetic wire accommodation holes running through the upper and lower surfaces of the fixing module is arranged inthe fixing module in array, the soft magnetic wires correspond one by one and are mounted in the corresponding soft magnetic wire accommodation holes, and the depth of the soft magnetic wire accommodation hole is matched with the length of the soft magnetic wires; the cross section size of the soft magnetic wire accommodation holes is matched with the cross section size of the soft magnetic wires; the fixing module is mounted on the upper surface of the permanent magnet, the array area corresponding to the soft magnetic wire accommodation holes is located in the weak magnetic field intensityarea of the center of the permanent magnet, and the soft magnetic wires are adsorbed on the surface of the permanent magnet and maintains an upright state under the limit of the soft magnetic wire accommodation holes. By the arrangement, fluid disturbance can be resisted, the spatial position of cell microcarriers can be accurately controlled, and orderly arrangement of the cell microcarriers in liquid environment is realized.

Description

technical field [0001] The invention relates to the technology of constructing artificial tissue scaffolds by using cell microcarriers, in particular to a device for guiding the distribution of magnetic induction intensity in a lattice for assisting in the assembly of magnetic cell microcarriers, and belongs to the technical field of three-dimensional cell assembly in tissue engineering. Background technique [0002] Various unpredictable natural disasters and behavioral accidents are likely to cause tissue damage and organ loss, and the aging and degeneration of tissues and organs also threaten human health. Tissue engineering develops artificial tissues with human organ functions through three-dimensional assembly of cells, which provides a new way for organ repair and regeneration. Human tissue is an ordered structure composed of a variety of cells. How to realize the precise spatial arrangement of different cells is a difficult problem in the development of cell three-di...
