The fat necrosis risk monitoring system comprises an oxygen saturation detection device used for obtaining oxygen saturation information of a transplantation area and a contrast area; the temperature detection device is used for acquiring temperature information of the transplantation area and the contrast area; the pressure detection device is used for acquiring pressure information of the transplantation area and the contrast area; the data acquisition device is electrically connected to the oxygen saturation detection device, the temperature detection device and the pressure detection device and is used for acquiring information detected by the oxygen saturation detection device, the temperature detection device and the pressure detection device; and the upper computer is electrically connected to the data acquisition device and is used for acquiring the data acquired by the data acquisition device and processing the acquired data. According to the invention, the fat necrosis comprehensive risk coefficient of the transplantation area can be obtained, so that an accurate quantitative index is provided for evaluation and nursing work after fat transplantation.

The specification relates to a method of manufacturing a diabetic foot patient-specific skin regeneration sheet, and a diabetic foot patient-specific skin regeneration sheet. The method includes extracting autologous adipose tissue, removing fibers in the autologous adipose tissue, crushing the autologous adipose tissue, and acquiring an adipose tissue extract by filtrating the crushed autologous adipose tissue.

The application discloses a kind of composite protein gels and preparation method thereof, its preparation method includes the following steps: with the blood collection tube with anticoagulant is collected blood;The above-mentioned blood is centrifuged at 300-700g centrifugal acceleration at room temperature 10-20min;After centrifugation, blood is transferred to biological safety cabinet, and the upper plasma layer is extracted, and then it is placed in-80 ℃ ultra-low temperature refrigerator and rapidly frozen, and the freezing time is 24-72h;Then, the frozen plasma is taken out, and freeze-drying treatment is carried out under the condition that the temperature is-55-65 ℃ and the pressure is 50-100Pa, and the freeze-dried plasma is prepared;Calcium chloride injection is added to the freeze-dried plasma at a volume ratio of 1:0.5-2, then reacted in a water bath at 60-90 ℃ for 5-15min, and removed to prepare.The protein gel can effectively solve the problem of easy skin stiffening, collapse, high in vivo absorption rate and poor filler stability caused by hyaluronic acid and autologous fat.

The utility model discloses an autologous fat component separation filler, and relates to the technical field of fat filling. Comprising a main body, the main body is composed of a push-injection cylinder and a filling cylinder, the lower inner wall of the push-injection cylinder is fixedly sleeved with a sealing plate, one end, away from the sealing plate, of the push-injection cylinder is rotatably provided with a push-injection knob, the surface of the push-injection knob is sleeved with a lead screw in a penetrating and threaded mode, and a push rod is fixedly installed at the end of the lead screw and slides at the bottom of the sealing plate in a limited mode; a piston head is fixedly installed at the end, away from the lead screw, of the push rod and sleeved with the inner wall of the filling cylinder. The push injection knob is rotated to drive the screw rod in threaded engagement with the push injection knob to move up and down, and in the process, the sliding groove slidably sleeves the surface of the convex block to play a limiting role, so that the piston head makes piston motion on the inner wall of the filling cylinder, constant-speed separation and filling of autologous fat are achieved, and the filling speed can be accurately controlled; therefore, the survival rate of fat cell transplantation is improved.

The present invention relates to a fat processing device, specifically a fat processing device for autologous reinjection in aesthetic and reconstructive medicine. The fat processing device comprising a container, a lid, a filter element and an impeller.

The invention discloses autologous fat transplantation equipment for increasing the survival rate of fat cells, and relates to the technical field of fat cell transplantation. Comprising an adipocyte transplantation processing mechanism, the adipocyte transplantation processing mechanism comprises a cell transplantation box, and a control panel is installed on the surface of the cell transplantation box; the device can conveniently extract transplanted and extracted fat cells, is beneficial to efficiently treating the transplanted fat cells, improves the fat cell transplantation and extraction effect, reduces the probability of errors caused by manual extraction of the fat cells by medical staff, can ensure that the fat cells are transplanted and extracted in a closed and sterile environment, and improves the survival rate of the fat cells. The fat cell transplantation and extraction device is simple in structure and convenient to use, the survival rate of fat cell transplantation and extraction is increased, medical articles for fat cell extraction can be stored, medical staff can conveniently operate in the fat cell transplantation and extraction work, the fat cell transplantation efficiency of the medical staff is improved, and convenience is provided for the staff.

The utility model provides an autologous adipose-derived stem cell kit which comprises a cuboid layered box body, and the layered box body is formed by sequentially connecting a sterile collection layer, an enzymolysis filtering layer, a centrifugal separation layer, a culture amplification layer and a low-temperature cryopreservation layer from top to bottom; the adjacent upper-layer structure and lower-layer structure are separately connected through a sealing buckle, and directional flowing of liquid is achieved through a one-way valve. An injector preloaded with anticoagulant and a blunt-end fat collection needle are arranged in the sterile collection layer, so that tissue damage is reduced. The autologous adipose-derived stem cell kit provided by the utility model can enable the existing kit to have the technical effect of multiple functions, can be used for extracting, amplifying and storing autologous adipose-derived stem cells, and has the technical effects that the whole process is closed, the operation is simple and convenient, and the cell viability can be improved.
