Problems solved by technology

[0003] However, the method of cryolipolysis to remove the heat in the subcutaneous tissue is relatively simple. In the way of transdermal cooling, the temperature of the fat tissue is lowered, and the skin tissue is also challenged by a lower temperature, which is prone to the risk of skin frostbite. At present, there is not much The best way to prevent skin frostbite

preparation example Construction

[0063] Further, the preparation method of the liquid guide 10b includes the following steps: making the degradable material into a thin film of the required shape, then injecting antifreeze injection preparation to form the liquid guide part 120, and then using the hot injection molding method of the mold to form the liquid guide part 120. 120 is integrated on the first substrate 110b. It can be understood that, in the process of thermal injection molding using a mold, the injection hole formed when injecting the antifreeze injection formulation is fused with the first substrate 110b to form a sealed film.

[0064] Furthermore, each liquid guiding part 120 is in a zigzag shape; further, each liquid guiding part 120 is in the shape of a cone; furthermore, each liquid guiding part has a height of 1.5-2 mm, a bottom surface diameter of 50-200 μm, and adjacent The distance between the two liquid guides 120 is 500 μm to 1000 μm, and the amount of antifreeze injection preparation fi...

Abstract

The invention relates to an anti-freezing solution injection preparation for assisting in freezing and lipolysis, a liquid guide device, a kit and a freezing and lipolysis system. Wherein the freezing point of the anti-freezing solution injection preparation assisting in freezing andlipolysis is lower than-10 DEG C, and at the temperature of 20-40 DEG C, the viscosity of the anti-freezing solution injection preparation is 1-1000 cps, and the pH value is 6.5-7.5. According to the anti-freezing solution injection preparation assisting in freezing and lipolysis, the injection device, the kit and the freezing and lipolysis system, skin frostbite can be effectively prevented on the basis of ensuring the treatment effect.

Description

technical field [0001] The invention relates to the technical field of cryolipolysis, in particular to an antifreeze injection preparation, a fluid guide, a kit and a cryofat system for assisting cryofat melting. Background technique [0002] Cryolipolysis, also known as cryofat reduction, utilizes the characteristic that fat-rich cells in the human body are more sensitive to low temperature than other non-fat-rich cells, and sends freezing through the skin to the designated fat-reducing parts through a non-invasive device, so that The fat cells in this area undergo apoptosis under the action of cold stimulation, and then are excreted by the body's own metabolism, so as to achieve the purpose of fat reduction. Compared with other non-invasive fat reduction techniques, cryolipolysis is the most effective non-invasive fat reduction method, and its average fat reduction rate can reach 25%. [0003] However, the method of cryolipolysis to remove the heat in the subcutaneous tis...
