Description

technical field [0001] The invention relates to a magnetocaloric device, in particular to an adjustable magnetic field generating device. Background technique [0002] Magnetic hyperthermia is to deliver the magnetic drug carrier to the treatment area or specific target tissue or cells, under the action of an external alternating magnetic field, the magnetic particles generate heat due to magnetic loss to control the drug release and release kinetics of the drug-loading system, improving Drug efficacy and drug utilization. Because magnetic fields can penetrate human tissues, have no effect on the human body, and have little side effects, magnetic fields are considered to be a promising tool for enhancing the efficacy of drugs in clinical treatments. At present, there is no ready-made commercial magnetothermal device that can control the magnetic release of drugs, and most of the experimental researches are relatively simple and crude magnetic field devices, which are still ...
