This invention relates to the field of medical high-fidelity training model technology, and discloses a multi-vascular network biomimetic hemostasis model and method for junctional wounds. The model includes a biomimetic model, a blood bank system, a control system, and a temperature control unit. A biomimetic multi-vascular network is embedded in the junction area of ​​the biomimetic model, and a biomimetic wound opening is provided at the corresponding position of the biomimetic multi-vascular network. The input end of the biomimetic multi-vascular network is connected to the output end of the blood bank system, and the output end of the biomimetic multi-vascular network is located inside the biomimetic wound opening. The temperature control unit is located at the input end of the biomimetic multi-vascular network. A pressure sensor is provided in the biomimetic wound cavity wall of the biomimetic wound opening, and hemostatic material is filled inside the biomimetic wound opening, with the hemostatic material in contact with the pressure sensor. The control terminal of the control system is electrically connected to the blood bank system, the temperature control unit, and the pressure sensor. This invention can realistically simulate the bleeding process of penetrating and blind-tube injuries in the junctional wound of the simulation model, facilitating simulation training.

The invention relates to the technical field of flexible light-emitting devices, in particular to a flexible OLED screen curl packaging structure which comprises a substrate, a first electrode layer, a light-emitting function layer, a second electrode layer and a protective layer, the substrate, the first electrode layer, the light-emitting function layer, the second electrode layer and the protective layer are sequentially distributed, a filler cavity is formed in the protective layer, and the filler cavity is filled with a filling material. A filler is arranged in the filler cavity, and catalysts are arranged on the portions, located on the two sides of the filler cavity, of the base plate. According to the invention, the filler cavity is arranged and the catalyst is arranged between the protective layer and the substrate, so that when the edge of the OLED screen is torn, the filler in the filler cavity flows out and is in contact with the catalyst so as to repair side packaging, thereby avoiding the problem that internal electronic components are damaged due to contact with air due to edge tearing of the OLED screen; therefore, the service life of the OLED screen is effectively prolonged.

The utility model relates to the technical field of chemical fiber filament processing, in particular to a chemical fiber filament cutting machine material receiving mechanism, a cutting machine, a pressure applying mechanism and a collecting mechanism, the pressure applying mechanism is arranged on one side of the cutting machine, and the collecting mechanism is arranged on the outer side of the bottom of the pressure applying mechanism. The pressure applying mechanism comprises a mounting side plate, an oil cylinder frame, a first oil cylinder, a pressure applying block, a collecting cover and a clamping mechanism, the mounting side plate is fixed to one end of the cutting-off machine, and the oil cylinder frame is fixedly arranged at the top of the outer side of the mounting side plate. Fluffy chemical fibers are pressed into a packaging bag through the pressure applying mechanism, a bag opening of the packaging bag can be effectively fixed to the bottom of the collecting cover through the clamping mechanism, bag opening falling caused by pressing is avoided, and the bottom collecting mechanism adjusts the height of a bottom bearing disc of the bottom collecting mechanism according to the amount of the chemical fibers contained in the packaging bag; therefore, the packaging bag is gradually controlled to unfold along with the increase of the chemical fiber collection amount.

The invention discloses an anti-seepage ecological protection slope for farmland erosion gully treatment, and relates to the technical field of farmland treatment. The invention aims to solve the problems that in the prior art, a honeycomb ecological protection slope for preventing and treating farmland erosion gullies is good in ecological property and not good enough in stability, and landslide and collapse often occur; and traditional gabion slope protection modes and the like are adopted, the stability is good, however, farmland is prone to being damaged when erosion gabions are prevented and controlled, and the ecological property of the farmland is damaged. The anti-seepage ecological protection structure is formed by sequentially connecting an anti-seepage ecological protection section, a transition section, a stilling pool section and a confluence reinforcing section. The water inlet end of the erosion gully is provided with an anti-seepage type ecological protection section composed of honeycomb ecological protection slopes and then is a transition section composed of Reynolds protection slopes, and the rear portion of the transition section is sequentially connected with a stilling pool section composed of gabion protection slopes and a confluence reinforcing section. And the stilling pool section is provided with a stilling ditch. The method is used for farmland erosion gully treatment.
