Size-classifier of adipocyte cells and liposuction system comprising same

A size-classifier (12) for dividing adipocyte cells into specific size fractions, the size-classifier comprising,

• a classifier vessel (12v) having a classifier floor (12f), a classifier wall (12w) having a geometry of revolution about a classifier axis (Z12) and an open end closed by a classifier lid (13) and defining a classifier inner volume,
• a carousel (14) rotatably mounted in the classifier inner volume to rotate about the classifier axis (Z12), and comprising,
• a carousel vessel (14v) having a carousel floor (14f), a carousel wall (14w) which has a geometry of revolution about the classifier axis (Z12) and an open end defining a carousel inner volume, wherein
• the carousel inner volume is divided into a plurality of compartments (14.1-14.n) separated from one another by compartment walls, each compartment wall comprising a transverse wall portion which is transverse to a radial direction of the carousel wall (14w),
• a classifier inlet opening (12i) in the classifier lid in registration with the carousel and configured for giving a needle direct access to the compartments (14i),
• a classifier outlet opening (12o) in the classifier floor (12f) configured for evacuating liquids,
• a driving coupling element (16c) configured for driving a rotation of the carousel (14) relative to the classifier vessel (12v) when coupled to a motor (M),
• Characterized in that,
• the transverse wall portion separating a first compartment (14.1) from a second compartment (14.2) comprises a mesh of first opening (R1),
• the transverse wall portion separating an ith compartment (14.i) from a (i+1)th compartment (14.(i+1)), with i=2 to (n−1), comprises a mesh of ith opening (Ri), smaller than an (i−1)th opening (R(i−1)) of a transverse wall portion separating a (i−1)th compartment (14.(i−1)) from the ith compartment (14.i), (i.e., R(n−1)<R(n−2) . . . <Ri< . . . <R1),
• the carousel floor of the nth compartment (14f.n) comprises an opening in fluid communication with the classifier floor (12f) and with the outlet opening (12o).
