Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a SVF processing and collection component. Background Art

[0002] SVF (Stromal Vascular Fraction) is a group of heterogeneous cells that surround fat cells in adipose tissue. They can be obtained from adipose tissues such as the abdomen, buttocks, breasts, and internal organs of humans. Currently, the method for obtaining SVF is to obtain adipose tissue after liposuction, wash to remove blood cells, digest with collagenase to obtain a single cell suspension, and filter through a 0.22um filter to remove undigested tissue residues. Because of the light specific gravity of fat cells, the precipitate obtained after centrifugation is SVF.

[0003] At present, the absorption, processing and separation of fat in the human body are all carried out using different devices. The fat needs to be manually transferred between different devices, and the degree of automation is low, which cannot meet clinical needs. Utility Model Content
