The utility model provides a one-way sealing soluble bridge plug, and belongs to the field of bridge plugs. The one-way sealing soluble bridge plug comprises a center pipe and a guiding shoe connected to the lower end of the center pipe, the guiding shoe is provided with an extending section protruding out of the lower end wall of the center pipe in the axial direction, the extending section is provided with a center hole coaxially communicated with the center pipe, and the inner wall of the center hole of the guiding shoe and / or the inner wall of the center pipe are / is provided with a flow guide groove allowing flow-back liquid to bypass the fracturing ball. The flow guide grooves are formed in the inner wall of the center pipe and / or the inner wall of the center hole of the guide shoe, so that the surface area of the center pipe and / or the guide shoe is increased, the dissolving speed of the center pipe and / or the guide shoe is increased, flowback liquid can still flow smoothly when the fracturing ball is clamped into the center hole of the center pipe or the guide shoe, and the fracturing effect is improved. And the fast dissolving speed of the one-way sealed soluble bridge plug is ensured.

The invention relates to a grinding device for pharmacy. The grinding device comprises a supporting base, a tamping rod frame is connected to the supporting base, a grinding tank is arranged on the lower portion of the tamping rod frame, an electric secondary telescopic rod is connected to the upper portion of the tamping rod frame, a grinding block is connected to the telescopic end of the electric secondary telescopic rod, and a driving piece is connected between the tamping rod frame and the grinding tank. The technical scheme of the invention has the beneficial technical effects that the electric secondary telescopic rod is adopted to drive the grinding block to realize lifting, extruding and grinding, so that each medicine raw material can be in uniform contact with the extruding and grinding surface of the grinding block, the problem of non-uniform grinding caused by local accumulation and corner residues of medicines is effectively avoided, and the granularity consistency of final ground products is ensured. The synergistic grinding mode is especially suitable for scenes with high requirements on the fineness of medicine powder in pharmaceutical research and preparation production, high-quality raw materials can be provided for subsequent medicine dissolution, mixing and preparation forming, and the dissolution rate and the medicine effect stability of the medicine are indirectly guaranteed.

The present invention belongs to the technical field of fermented extract preparation, and specifically relates to a mulberry leaf fermented extract with a slow-release sugar effect, and a preparation method and application thereof. The present invention first adds saccharomyces cerevisiae separated from the surface of mulberry leaves while ensuring that the content of 1-deoxynojirimycin in the mulberry leaf extract remains unchanged, and utilizes the method of microbial fermentation to fully release and retain the nutrition and active ingredients of the mulberry leaves, and ensures the dissolution rate of the active ingredients of the mulberry leaves while also ensuring safety; secondly, the use of organic solvents is reduced by fermentation, and environmental pollution is avoided; again, the bitterness of the mulberry leaf extract is reduced or even avoided, and the fragrance of mulberry leaf tea is improved; finally, the microbial varieties in the method are easy to obtain, the fermentation process is simple, the use cost is low, and the microbial fermentation is efficient and repeatable, whether it is laboratory small-scale preparation or factory large-scale production, it has cost advantages and has good practical application value.
