Description

Continuous airtight aseptic fat collection device Technical Field The invention relates to the technical field of fat suction equipment, in particular to a continuous closed sterile fat collecting device. Background The human adipose-derived stem cells (human adipose-DERIVED STEM CELLS, hADSCs) are mesenchymal stem cells extracted and separated from human adipose tissues, have the advantages of readily available materials, small immunogenicity, large-scale in vitro culture and the like, and have good curative effects in regenerative medicine and medicine. At present, adipose stem cells produced by university laboratories and enterprises are all from adipose tissues obtained by liposuction in hospitals. Most of adipose tissues are obtained from the abdomen, the inner side and the outer side of the thigh and the two arms of a patient in a liposuction mode, swelling liquid is injected into a liposuction part, and negative pressure is formed through a liposuction needle with a length of 3-5 mm so as to be sucked into a lipocollection bottle. Hospital staff typically transfers adipose tissue from a lipid-collecting bottle to a syringe in an operating table or room or transfers adipose tissue to a sterile container using a pouring method, a pipette transferring method, and then transports to a laboratory or business, and bacteria or fungi may be introduced during the transfer, thereby contaminating the adipose tissue.
