This invention discloses an electrode implantation tool. The distal end of the electrode is provided with a fixing component. The implantation tool includes an outer sheath and an inner sheath. The inner sheath includes an inner sheath tube and a first handle. The outer sheath includes an outer sheath tube and a second handle. The inner sheath tube can be inserted into the outer sheath tube. The first handle can be locked within the second handle. The second handle has at least a first locking position and a second locking position in the axial direction, allowing the first handle to move from the first locking position to the second locking position. The inner diameter of the inner sheath tube is smaller than the outer diameter of the fixing component, and the inner diameter of the outer sheath tube is larger than the outer diameter of the fixing component. Other parts of the electrode, excluding the fixing component, can be inserted into the inner sheath tube. This invention allows for a single puncture of the electrode and implantation tool near the target nerve tissue. After successful testing, the electrode is directly released and fixed, ensuring consistency between the test point and the implantation point.

This invention belongs to the field of food processing technology, specifically relating to a low molecular weight *Hydrangea hygroscopica* polysaccharide microsphere for relieving fatigue, its preparation method, and its application. The preparation method includes the following steps: (1) extraction of crude polysaccharide from *Hydrangea hygroscopica*; (2) degradation; (3) encapsulation: the low molecular weight *Hydrangea hygroscopica* polysaccharide obtained in step (2) is dripped into CaCl2 solution through electrospray treatment to form a gel core, and the gel core is encapsulated to obtain the low molecular weight *Hydrangea hygroscopica* polysaccharide microspheres. The beneficial effects of this invention are: this invention efficiently extracts *Hydrangea hygroscopica* polysaccharide through steam explosion-pulsed electric field synergy, accurately prepares 10-20 kDa high-activity low molecular weight fragments through compound enzymatic hydrolysis-ultrasound-ultrafiltration, and finally constructs colon-targeting microspheres using electrospray-layer-by-layer self-assembly. These microspheres can protect the active ingredients and allow them to reach the colon for release, significantly improving the bioavailability and anti-fatigue effect of the polysaccharide.

This utility model relates to the field of check valve technology, specifically to a check valve structure for unloading and separating from shipboard and vehicle loading. It includes a valve body, with a control component mounted on the outer wall of the valve body. The inner wall of the valve body has two interconnected conical cavities, each with a valve core assembly mounted on its inner wall. A drive component connected to the control component is mounted at the midpoint of the inner wall of the valve body. A liquid flow direction sensor is mounted on the outer wall of the drive component. Flanges are fixedly connected to both ends of the valve body. This utility model overcomes the shortcomings of existing technologies by incorporating two valve core assemblies within the valve body. The valve core assemblies facilitate control of the flow at both ends of the valve body. The cooperation between the drive component and the control component allows for easy adjustment and control of the two valve core assemblies, improving their stability and solving the problem of poor stability in existing check valves affecting normal liquid transport.

The application belongs to the technical field of olefin polymerization, and discloses a fluorine aryl borate compound dispersion system, a preparation method and application thereof, the preparation method comprising the following steps: 1) dissolving the fluorine aryl borate compound in a good solvent to prepare a saturated solution; 2) under the action of stirring and ultrasonic, the saturated solution is added into a poor solvent, and after the addition is completed, the stirring and ultrasonic continue for 3-10 minutes; 3) the suspension obtained in the step 2) is filtered to obtain a solid, the solid is dried by blowing hot nitrogen gas under stirring, and then the solid is treated at high temperature under reduced pressure; 4) the solid obtained in the step 3) is dispersed in an alkane solvent to obtain the fluorine aryl borate compound dispersion system. The preparation method has low process cost, and the particle size of the fluorine aryl borate compound in the prepared dispersion system is adjustable and the purity is improved.
