Abstract: A method and device for isolating tissue cells from a liquid is provided for integrating a mixture of the tissue cells and the liquid into a vacuum stream and isolating again from the vacuum stream in a tissue collection container (13). The tissue cells are filtered out of the mixture by means of gravity and the remaining liquid is re-integrated into the vacuum stream. In order to further develop said method and device to improve the care of the tissue cells and to reduce the filtration time, the vacuum stream that is isolated from the mixture inside the tissue collection container (13) is temporarily interrupted in order to generate a pressure that also acts on the mixture. In terms of the device, the connection between the lower collection chamber (23) for the liquid and the upper vacuum chamber (25) is formed by a blockable bypass line (27).

Abstract: The invention relates to an apparatus for separating tissue cells from a fluid, with a collection container forming a collection space, which is connected, on one hand, with a negative pressure source and which is connected, on the other hand, with a supply line for the fluid-tissue cell mixture. It is provided that inside the collection space (18) a communicating tube (16) is arranged, which terminates at a distance from the bottom (17) of the collection container (14), wherein a connection is provided between the communicating tube (16) and the collection space (18) above a fluid-tissue cell mixture level (22) established in the collection container (14), and a suction element (20) which is connected with the negative pressure source (6) is arranged inside the communicating tube (16).

Abstract: The invention relates to a method for transporting a fluid for generating a fluid jet, wherein the fluid is delivered from a pump under pressure with a predetermined volume flow to an exit opening. In the event of an interruption of the volume flow, the pump is automatically switched from an operating mode for generating pressure to an operating mode for suctioning fluid; and a device for producing a volume flow for realizing a fluid jet for cutting and/or flushing of material, comprising a pump with an operating mode for generating pressure in the fluid and for generating suction. The device is constructed such that during interruption of the set volume flow, the pumpcan be switched over or switches over automatically from the operating mode for generating pressure to an operating mode for generating suction for the purpose of suctioning fluid.

Abstract: The invention relates to a method for separating adult stem cells from fatty tissue, wherein the fatty tissue is mixed with a fluid and the stem cells are subsequently separated. The fatty tissue with fat cells and adult stem cells is exposed to a fluid jet (38) having a pressure adjusted such that the adult stem cells are separated from the fat cells and the adult stem cells are separated from the fat cell-stem cell-fluid mixture. A container (12) is provided for receiving fatty tissue removed from a biological structure, which includes fat cells (62) and adult stem cells (64), wherein the container (12) has a feed device (28) for a pressurized fluid and the feed device (28) includes an outlet the arrangement (30) for the fluid which is introduced or can be introduced into the fatty tissue.

Abstract: The invention relates to a device for fluid jet-supported separation and suctioning of tissue cells from a biological structure, with a pressure generator for supplying a defined fluid jet to an applicator of the device, with a suction device for removing the separated tissue cells and the used fluid from the biological structure, wherein the suction device includes a vacuum source and a suction line for connecting the applicator with the vacuum source, wherein a tissue cell collector is incorporated in the suction line. It is provided that a catch device (16) for catching connecting tissue and the like from the fluid-tissue cell mixture is arranged upstream of the tissue cell collector (13).

Abstract: In order to provide a work area that is as large as possible, and to shield off the environment, and in order to simultaneously provide for a mobile application, the discharge nozzle (11) and the suction opening (12) are disposed in a protective cover (6, 6?, 6?, 6??). The protective cover (6, 6?, 6?, 6??) and the body parts of the patient conjointly form a defined vacuum-sealed work chamber (8). The protective cover is made of a transparent material.
