Abstract
The present disclosure relates to a system for washing lipoaspirate, comprising a chamber; a lid connecting to the top side of the chamber and comprising a harvest port configured to connect to and receive a harvested lipoaspirate from a hose; a sub-assembly comprising a mesh basket and disposed in an upper portion of the chamber, the sub-assembly configured to drain the lipoaspirate through the mesh basket; a tray located in a lower portion of the chamber and comprising a foam assembly configured to concentrate a drained lipoaspirate; and an extraction port along a side wall of the chamber and configured to permit extraction of a concentrated lipoaspirate from the system.
Claims20
A system for washing lipoaspirate, comprising:
- (a) a chamber comprising a hollow body formed of side walls having an exterior surface and an interior surface, the chamber being open at a top side and a bottom side of the chamber;
- (b) a lid comprising:
- (i) a top surface;
- (ii) a lip extending downward from a bottom surface of the lid and configured to securely connect the lid to the top side of the chamber, and
- (iii) a harvest port comprising a cylindrical tap extending outwardly from the top side of the lid and configured to connect to and receive a harvested lipoaspirate from a hose;
- (c) a sub-assembly comprising a mesh basket and disposed in an upper portion of the chamber, the sub-assembly configured to receive the lipoaspirate received through the harvest port and to separate extracted waste fluid from the lipoaspirate to form a washed lipoaspirate;
- (d) a tray configured to insert into a lower portion of the chamber through an opening in the side walls, thereby forming a bottom portion of the system, the tray comprising:
- (i) a plate;
- (ii) raised sidewalls positioned along the entire perimeter of the plate and extending upward from a top surface of the plate;
- and
- (ii) a foam assembly fitting onto the plate and within the sidewalls so that the foam assembly is disposed in a lower portion of the chamber and configured to concentrate the washed lipoaspirate;
- and
- (e) an extraction port along one of the side walls of the chamber configured to permit removal of lipoaspirate that has been one of washed and concentrated.
A method for washing a harvested lipoaspirate with a lipoaspirate washing system, the method comprising:
- (a) receiving the harvested lipoaspirate into a chamber of the lipoaspirate washing system so that the harvested lipoaspirate is contained by a mesh basket disposed in an upper portion of the chamber of the lipoaspirate washing system to form a received lipoaspirate;
- (b) adding a washing solution to the chamber and mixing the washing solution with the received lipoaspirate using a spatula to form a mixed lipoaspirate;
- and
- (c) separating the mixed lipoaspirate into an extracted waste fluid and a washed lipoaspirate.
