This utility model relates to the field of textile fabrics, and more particularly to a green and environmentally friendly fabric, comprising a reinforcing surface layer and an environmentally friendly base layer. A heat-melting yarn is disposed between the reinforcing surface layer and the environmentally friendly base layer. The environmentally friendly base layer is made of regenerated cellulose fibers. The top and bottom ends of the heat-melting yarn are fixedly connected to the reinforcing surface layer and the environmentally friendly base layer, respectively. The heat-melting yarn is woven from heat-melting fibers. The reinforcing surface layer is woven from fiber bundles, which include tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers. The tensile fibers, flame-retardant fibers, absorbent fibers, polyester fibers, and corrosion-resistant fibers are bundled together to form a tight structure. This invention solves the technical problems of insufficient environmental performance and functionality in traditional fabrics.

This utility model discloses an adjustable steam flow rate umbilical therapy device for traditional Chinese medicine, relating to the field of umbilical therapy technology. The device includes: a mounting block with an adhesion ring on its outer side; and an adjustment mechanism located on the outer side of the mounting block, comprising a fixing block and an outlet pipe. An opening is formed on the outer side of the mounting block, and the outlet pipe is housed within the opening. Five sets of outlet holes are formed on the outer side of the outlet pipe, and a fixing block is fixedly mounted on the outer side of the outlet pipe. By rotating a knob, the knob moves on a threaded cylinder, causing the fixing block to move under the guidance of the mounting cylinder. This moves the outlet pipe within the fixing cylinder, positioning the outlet holes within the opening of the mounting block. The outer side of the outlet pipe fits against the inner side of the mounting block, effectively blocking the outlet and reducing the steam flow. This controls the steam flow rate, preventing excessive steam flow and temperature from causing burns to the patient's skin, reducing safety hazards, and improving the therapeutic effect.

This invention provides an external fixation frame for limb fractures, relating to the field of fracture fixation technology. It includes a main fixation component, a secondary fixation component, a length adjustment component, an angle adjustment component, a fixation element, and a movement component. The main fixation component includes a main fixation frame with a main adjustment groove on its long side and main through-channels on both its upper and lower sidewalls. The secondary fixation component includes a secondary fixation frame with a secondary adjustment groove on its long side and secondary through-channels on both its upper and lower sidewalls. The length adjustment component allows for adjustment of the distance between the two fixation positions, making it suitable for fractures of different lengths. Furthermore, the use of a drug-eluting silicone sleeve effectively inhibits early bacterial colonization, significantly reducing the risk of pin tract infection and secondary loosening.

This application provides a self-generating nano-silver PVDF composite fiber, comprising polyvinylidene fluoride (PVDF) and nano-silver, which are combined via electrospinning. By introducing AgNPs into the piezoelectric material PVDF and fabricating it into micro-electric nanofibers using electrospinning, this fiber possesses both the long-lasting, broad-spectrum antibacterial properties of nano-silver and the ability to continuously generate microcurrents on the wound surface. It does not rely on external devices such as fixed power supplies and electrode pads required for commonly used clinical electrical stimulation, making it highly significant and effective in reducing post-burn / traumatic infection, promoting wound healing, and ensuring patient safety and timely recovery. This solves the problem of poor stability and environmental limitations of PVDF nanocomposite membranes, which negatively impact wound healing. This application also provides a method for preparing the self-generating nano-silver PVDF composite fiber and its application in preparing dressings for treating burns and wounds.

The embodiment of the application discloses a circulating water aquaculture system, comprising: an aquaculture pond, a solid-liquid separation device, an elevator, a protein separator, a biochemical water treatment device and a backflow unit, the aquaculture pond, the solid-liquid separation device, the elevator, the protein separator and the biochemical water treatment device are sequentially arranged along a water inlet direction, and the backflow unit is connected with the biochemical water treatment device and the aquaculture pond. The circulating water aquaculture system can make the treated aquaculture wastewater backflow to the aquaculture pond for recycling, so that the aquaculture pond only needs to supplement a small amount of water, which can greatly save water resources, greatly reduce the infection of pathogenic bacteria brought by additional water, and effectively improve the aquaculture density and the aquaculture quality.

This utility model discloses a depth-limiting sheath assembly for endoscopic-assisted anterior cervical surgery, comprising an outer sheath and an inner sheath, the inner sheath being inside the outer sheath. The outer sheath has a depth-limiting locking block at its tip, which, during operation, can be locked in front of the cervical vertebrae to limit the depth of the sheath and endoscope. One end of the outer sheath is fixedly connected to a receiving cavity, and a pressure block is disposed within the receiving cavity. One end of the pressure block is connected to the receiving cavity via a first spring, and the pressure block is slidably connected to the receiving cavity. This utility model provides a depth-limiting sheath assembly for endoscopic-assisted anterior cervical surgery, which, through the relative movement of the spring-loaded pressure block between the endoscope and the sheath, limits the depth and allows for relative adjustment of the endoscope's position, facilitating observation of the intervertebral discs.

This invention provides a compound prebiotic concentrate for enhancing the performance of fast-moving consumer goods (FMCG) food, its preparation method, and its application, belonging to the field of prebiotic technology. The compound prebiotic concentrate for enhancing the performance of FMCG food comprises the following components in parts by weight: 10-20 parts fructooligosaccharides, 15-25 parts isomaltooligosaccharides, 10-20 parts galactooligosaccharides, 4-10 parts synergistic agents, and 10-20 parts water. This prebiotic concentrate promotes intestinal health, stabilizes blood sugar levels, reduces the risk of diabetes and colorectal cancer, and when added to food, has anti-weight-gain effects, improves the body's absorption of minerals such as calcium and magnesium, enhances the body's immune response, reduces the risk of infection and inflammation, and alleviates digestive problems such as constipation and diarrhea.
