Technical Field

The invention belongs to the field of medical material production, and particularly relates to a dispersing device for medical nano-material production.

Background

Nanotechnology refers to technology involving the use of parts per billion meters of material, i.e., technology involving dimensions between 1 and 100 nanometers. Nanotechnology has been applied in many fields and, as scientists continue to explore new ways for nanotechnology in the medical field, nanotechnology has shown considerable potential for use in medicine, for example, nanotechnology has shown great potential in the treatment of spinal cord injuries. Meanwhile, the molecules can be designed into a structure consistent with the nanoscale molecules in the spinal tissue by using a nanotechnology, and after the molecules are injected into blood by using an injector, the molecules can repair damaged neurons and stimulate the body to heal by itself, so that the damage caused by inflammation and scars can be prevented. In addition to making breakthroughs in the treatment of spinal cord injury, nanotechnology has also produced exciting results in terms of repairing the injury and restoring aging tissues. Scientists at state university in ohio developed a new technology called tissue nanotransfection technology. This technique helps transform skin cells into other types of functional cells that can then be used to repair the function of damaged tissues (e.g., nerves, blood vessels, and organs).

According to the above, the medical nano material using the nano technology has the characteristics of high specific surface area and high surface energy, but the medical nano material is easy to agglomerate in the transportation and storage processes, so that the inherent characteristics of the nano material are lost, and therefore, the medical nano material must be dispersed in advance in the use process to be better applied. Because the medical nano material has small particles and strong intermolecular action, the obtained particles are quickly agglomerated together to form a large agglomerate, and the general dispersing equipment can only primarily disperse the agglomerate, so that the fully and uniformly dispersed nano particles are difficult to obtain, the quality of the final medical nano material is influenced, and the quality of a product is reduced.
