Problems solved by technology
[0004]The existing autologous fat living cell filtration device uses cell sieves to filter, because there will still be adipose tissue that has not been digested and dispersed by collagenase in the adipose tissue digestion mixture, During the filtration process, the sieve hole will be blocked, and the filtration speed and filtration efficiency will be poor.

Abstract
The invention relates to the technical field of cell filtration and discloses an autologous fat active cell filter device for the plastic and cosmetic surgery. The filter device comprises a container, a cell sieve and a collector, wherein the cell sieve comprises a filter barrel, a flow collecting funnel is connected with the bottom of the filter barrel, the heavy-caliber edge of the flow collecting funnel is in sealing connection with the bottom edge of the filter barrel, and the minor-caliber end of the flow collecting funnel is communicated with an inner cavity of the collector; the filter device further comprises a separating barrel arranged between the container and the cell sieve; a suction tube is mounted at the top of the collector, one end of the suction tube is communicated with the inner cavity of the collector, and the other end is connected with a sucking pump. According to the filter device, fatty tissue digestive mixed liquor is pre-separated by the separating barrel, fatty tissue which is not digested completely and other large-particle impurities are removed, the problem that filter speed is affected by blockage of sieve pores of the cell sieve is solved, and the filter efficiency is improved; the cell sieve is utilized for further filtration, mixed cells such as red blood cells and the like in the pre-separated filtrate are filtered out, and follow-up centrifugal separation and purification of fat active cells are facilitated.
Description
technical field [0001] The invention relates to the technical field of cell filtration, in particular to an autologous fat active cell filtration device for plastic surgery. Background technique [0002] With the growth of age, human tissues age and the number of cells decreases, which in turn leads to signs of aging such as sagging, loss of elasticity, increased wrinkles, and even local depressions. This drives people to pursue various beauty-preserving techniques that are taken internally or externally. [0003] Adipose active cells are isolated from adipose tissue, which are not fully differentiated, immature cells, and cells with multi-directional differentiation potential. Because of the advantages of rich sources, convenient materials, and rich stem cells in tissues, adipose active cells are considered to be one of the ideal cell sources for tissue regeneration and repair. Autologous adipose active cells extract the adipose tissue from the waist, abdomen, buttocks, l...
