This invention proposes the construction of a simple closed loop system for continuous flow harvesting, collection, syphoning, and grafting of large volumes of fat. (See FIG. 1—a schematic of the overall setup). This invention uniquely bypasses the standard cumbersome and time-consuming process, that mainly being the need to first transfer fat into individual syringes prior to grafting into the patient. This is traditionally done with unmeasured, manual pressures as generated by a simple plunger syringe. It can be messy and sloppy, with loss of fat. In contrast, this innovative concept presented here simplifies the whole process into a closed loop, from the donor harvest site, and then back to the patient. The concept is modular, drawing on commonly used, interchangeable parts and pumps present and available in most basic community hospital operating rooms. The major benefit is a significant reduction in time to transfer. However there is also a simplification of the process with less air exposure time, consistent controlled limit on flow pressures, and a simple on off control that can be held in one hand. The system is adaptable to standard liposuction and introduction cannulas through standard liposuction tubing and a luer lock connection. Collection canisters are also interchangeable.
