The application belongs to the technical field of medical instruments, and particularly relates to a state detection and control method, a state detection and control device and a state detection and control medium.
Background
With the increasing living standard of people, the market demand for body-building products is gradually increased. Traditional non-invasive techniques for removing excess body fat include topical application of drugs, administration of weight loss drugs, exercise and diet. However, these lipid-reducing methods have limited treatment populations and in some cases have poor lipid-reducing effects. In addition, fat reduction methods using comprehensive systems generally do not achieve fat reduction to selective regions of the human body.
Although the disadvantages can be overcome by utilizing the non-invasiveness, effectiveness and selectivity of the frozen fat-dissolving, the skin is easily damaged in the frozen fat-dissolving process. Therefore, it is necessary to monitor the condition of the cryoapparatus and/or the skin during the process of freezing fat liquification and to take necessary measures to avoid the occurrence of skin freezing injury.
