Abstract

The invention discloses a directional cooling preparation device for microstructured biological materials, which relates to the technical field of microstructured biological materials. Cold column, one end of the first cooling column extends to the outside of the cold source tank and is inserted into the seal, the seal seals the cold source tank, the seal communicates with the material chamber, and the outlet of the material chamber is provided with a sealed thermal insulation cover , forming a directional conduction structure in which the cold source transfers energy to the material chamber along the first cooling column. The material chamber that can accommodate the material is set at the part of the device, so that the material is in contact with the first cooling column, the energy of the cold source is transferred to the material through the directional guidance of the first cooling column, and the direction of the cooling source is controlled, thereby controlling the ice crystals. Growth direction, reducing the difficulty of material preparation, high repeatability, good reproducibility, and controllable process.

Description

technical field [0001] The invention relates to the technical field of microstructure biomaterials, in particular to a directional cooling preparation device for microstructure biomaterials. Background technique [0002] Bone regeneration materials have always been one of the research hotspots of clinicians at home and abroad. The preparation of regular microstructure biomaterials is based on the frontier of bone tissue engineering development and has important bionic and application values. There are many ways to prepare them. For example, using existing Controlled cooling device, through the vacuum freeze-drying method, the solvent in the material is frozen at a low temperature, and the ice crystals in the material are directly sublimated under vacuum or low pressure to obtain a material with a certain microporous structure. The principle of this preparation method Simple, but the disadvantages are: (1) It cannot achieve directional cooling, that is, control the growth dir...
