The invention belongs to the technical field of perilla oil extraction, and discloses a perilla oil extraction device which comprises a tank body, a support is fixedly installed on the tank body, a ball head is fixedly installed on the support, the ball head is installed in a ball seat in a matched mode, and an outer cylinder is connected to the ball seat through a connecting frame. The inner cylinder is supported by the ejector rod and the guide wheel, so that the filter screen can be always kept in an inclined state, oil can be always naturally collected to a residue-free area in the filtering process, residues at a high position are promoted to be precipitated at a shallow layer under the action of oil flow, the filtering efficiency and the utilization rate of the filter screen are greatly improved, and the service life of the filter screen is prolonged. And in the process of collecting the residues, secondary recovery of grease can be realized through the permeation holes in the sleeve, so that the content of grease in the residues is reduced, the problem of grease waste is reduced, and the extraction rate of perilla oil is improved.

The present application belongs to the technical field of traditional Chinese medicine composition, and relates to a traditional Chinese medicine transdermal external preparation for treating vulvar hypopigmentation disease. The preparation is a paste prepared by mixing traditional Chinese medicine powder and horse oil. The traditional Chinese medicine powder is composed of the following raw materials by weight: Xuchangqing 10-12, Pugongying 10-15, Difusiduo 12-15, Tuzifuding 12-15, Baiji 10-15, Huzhang 9-12, Quansie 6-10, Diyu 10-12, Xuezhi 10-12, Danggui 6-10, Rushang 6-10, Miedu 6-10, Bingpian 1-3. The traditional Chinese medicine transdermal external preparation has definite and significant effects on vulvar hypopigmentation disease, especially in relieving intractable pruritus, promoting pigment recovery and improving skin sclerosis / atrophy. The traditional Chinese medicine transdermal external preparation has high safety, few adverse reactions and low recurrence rate.

The invention relates to the field of metal recovery, and particularly discloses a waste circuit board metal recovery device which comprises an acid-base pool and a liquid guide table arranged on the acid-base pool, a soaking cage is placed in the acid-base pool and comprises symmetrical containing frames used for containing broken circuit boards, hinged frames hinged to each other are arranged at one ends of the containing frames, and the hinged frames are arranged on the liquid guide table. Lifting ropes are arranged at the other end of the containing frame, and a second lifting head is fixed between the lifting ropes. The soaking cage is provided with the following two stations: a first station: a hoisting machine is used for hoisting along the hinging frame, so that the two containing frames are attached to each other; and in the second station, the hoisting machine hoists along the second hoisting head, so that the two containing frames are turned over along the hinge frame. According to the device disclosed by the invention, the seepage of internal liquid from the containing frames is accelerated through the two stations of separating and closing the two containing frames, so that the waiting time is shortened, the total time of batch leaching is shortened, and the efficiency of large-batch leaching is improved.

This application discloses a surgical incision protection device for postoperative umbilical morphology correction, comprising a main body and an observation window structure. The main body includes a drug layer, a support layer, and an antibacterial silicone layer. The drug layer is attached to the inner side of the support layer, and the antibacterial silicone layer is attached to the outer side of the drug layer. The observation window structure includes a rotatable turntable with a window fixed on it. An annular ring is fixed at the inner opening of the support layer. The observation window structure has a snap-fit ​​structure that is detachably connected to the annular ring. The turntable has a positioning structure to achieve long-lasting antibacterial protection. The closed-loop treatment system with precise drug release in the inner layer achieves the shaping of the surgical position and prevents surgical incision adhesion. The designed vents facilitate ventilation and fluid leakage, reducing the risk of infection. The rotatable observation window enables visual monitoring. The snap-fit ​​structure and adhesive tape enable quick assembly and disassembly, improving dressing change efficiency.

The transfer bucket comprises a cylinder with two open ends, a bottom plate is movably arranged at the bottom of the cylinder, the diameter of the bottom plate is larger than the outer diameter of the cylinder, a cross rib plate is fixedly connected to the bottom plate, a hanging rod is fixed to the upper portion of the rib plate, the position, close to the upper end, in the cylinder is connected with a cylinder through a plurality of connecting rods, and the hanging rod penetrates through the cylinder. A lifting ring is fixed to the top of the lifting rod, a nut is fixed to each of the two sides of the outer wall of the cylinder, a round rod is connected to each nut in a threaded mode, and two lifting holes are formed in the cylinder; the transfer bucket is arranged to be of a structure comprising a cylinder, a bottom plate, a hanging rod, a hanging ring and a cylinder, when the cylinder is loaded, the device is placed on the ground and located below a steel ball discharging port, after the device is full, the hanging ring can be hung through a crane for transferring, after transferring is completed, the cylinder is hung through the crane, the cylinder is separated from the bottom plate, and therefore the steel balls are unloaded; the steel balls can be unloaded without turning over the cylinder, the structure is simple, and operation is simpler and more convenient.

This invention belongs to the field of medical materials technology and discloses a simplified preparation method and application of an ECM paper scaffold. Specifically, an ECM paper scaffold is disclosed, prepared from decellularized ECM and hexafluoroisopropanol. The ECM paper scaffold provided by this invention has indentations and wrinkles of varying depths, as well as obvious through-holes, exhibiting good swelling rate, hydrophilicity, and permeability, and high tissue stability. Cells (such as HUVECs) can achieve rapid adhesion to the ECM paper scaffold, with visible tentacles adhering to the scaffold, and can extend and spread well, promoting cell proliferation, effectively promoting cell functional expression (such as promoting NO secretion by HUVECs), effectively promoting the deep penetration of nutrients and oxygen, and promoting cell growth.

The invention relates to the technical field of biology, in particular to a mouse liver cell extraction and cryopreservation method. Comprising the following steps: performing liver perfusion and digestion: performing inferior vena cava intubation on a mouse corpse, cutting open vena cava, clamping superior vena cava, performing perfusion with perfusate for 6-8 minutes, and performing circulating perfusion with digestive juice for 10-15 minutes; separating and purifying the cells: taking out the liver, tearing a liver membrane in precooling termination digestion liquid at 3-5 DEG C, filtering by a screen, collecting filtrate, performing primary centrifugation on the filtrate, supplementing a complete culture medium, then performing secondary centrifugation, collecting cell precipitates, washing with the complete culture medium for 2-3 times, performing centrifugation again, and retaining the cell precipitates at the bottom to obtain purified parenchymal liver cells; and resuspending the purified parenchymal hepatic cells by using a precooled cryopreservation solution until the final concentration is (1-2) * 10 < 7 > cells / mL, sub-packaging and cryopreserving. The method is stable in operation, high in cell obtaining rate, good in activity and high in recovery rate after cryopreservation.
