Title

Automatisches Abtrennen von Fettgewebe

Other Title
Device for separating fatty tissue from biological tissue, has plunger arranged in sleeve to be displaceably movable and closes off sleeve toward upper end such that space is formed within sleeve for receiving tissue
Abstract
(A1) Die Erfindung liegt auf dem technischen Gebiet des Tissue Engineering und betrifft ein Verfahren zum Abtrennen von an Spendergewebe des tierischen oder menschlichen Koerpers anhaftendem elastischem Gewebe sowie eine Vorrichtung zur automatischen Durchfuehrung dieses Verfahrens. Ein Anwendungsgebiet ist die Abtrennung von an Hautgewebe anhaftendem Fettgewebe, sodass ein von Fettgewebe im Wesentlichen befreiter Gewebeverband erhalten werden kann. Aus den abgetrennten Gewebeschichten koennen Einzelzellen isoliert werden. Die Erfindung betrifft auch die GMP-konforme vollautomatische Bearbeitung von Spendergeweben.

WO 2010130304 A1 UPAB: 20101125 NOVELTY - The device has a bottom element (40) which covers a lower end (12) of the sleeve and is set apart from a sleeve (10). A circumferential gap (50) is formed between the bottom element and lower end of the sleeve. A plunger (30) is arranged in the sleeve to be displaceably movable and closes off the sleeve toward an upper end (14) such that space (60) is formed within the sleeve for receiving the tissue. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) method for separating fatty tissue hanging from piece of biological tissue; (2) method for isolation of fatty tissue from donor tissue of the human or animal body; (3) usage method of device; and (4) arrangement for automatic isolation of biological cells from human or animal donor tissue. USE - Device for separating fatty tissue from biological tissue of human or animal body (claimed). ADVANTAGE - The automated process is designed so as to be able to be operated in a good microbiological practice (GMP) compliant manner. The modularity of the individual automation steps allows high flexibility with respect to the tissue used and the desired application, including the possibility of carrying out individual processing steps.
