A large-range grass seed sowing device and method based on grassland ecological restoration
PendingCN122498307Amaintain water retentionAvoid secondary ecological degradation
This invention discloses a large-scale grass seeding device for grassland ecological restoration, belonging to the field of grassland ecological restoration technology. The device includes a seeding frame with two rows of plow blades mounted on its lower surface, the blades being staggered in position. Each plow blade has a cutting section at its front end, which is triangular in shape, and a supporting section at its rear end, which has a symmetrical butterfly-wing structure. The cutting section cuts linear planting grooves into the soil. A connecting rod is rotatably connected to the rear end of the seeding frame via a bearing, and a pressing roller is rotatably connected to the end of the connecting rod. This invention employs a triangular cutting section for linear grooving, only subjecting the soil to narrow-slit, linear, and minimal disturbance. The working surface is narrow and the depth is controllable, without damaging the original structure of the grassland surface. It can completely preserve the crust layer and litter layer, maximizing the soil's water retention, soil stabilization, and wind erosion resistance, thus preventing secondary degradation of the grassland ecosystem from the source and truly achieving protective ecological restoration.

PendingCN121971410AAvoid sharp painImprove toleranceOrganic active ingredientsPharmaceutical non-active ingredientsPharmaceutical AidsBiodegradable polymer
The invention belongs to the technical field of pharmaceutical preparations, and discloses a treprostinil soluble microcrystalline patch and a preparation method thereof. Existing treprostinil mainly depends on intravenous injection or subcutaneous injection, the administration mode needs to be operated by professional medical staff, pain is brought to a patient, and the problems of infection risk, inconvenience in long-term administration and the like exist. The invention provides a treprostinil soluble microcrystalline patch and a preparation method thereof. The patch is of a layered structure and comprises a backing layer, a microcrystal array layer, an adhesive layer and a protective layer, and the microcrystal array layer is composed of treprostinil, a biodegradable polymer matrix material and auxiliary materials. The preparation method comprises the following steps: dissolving the components in a solvent to form a microcrystal stock solution, injecting into a mold, curing microcrystals through vacuum drying, and laminating and assembling with each layer of material. The microcrystalline patch disclosed by the invention can penetrate through a skin cuticle painlessly and noninvasively, so that efficient and continuous transdermal administration of treprostinil is realized, and many defects of an existing administration mode of treprostinil are overcome.

A cutting fixture and method
This invention discloses a cutting fixture and method applied to the removal of compressor moving blades in a gas turbine. The cutting fixture includes: a support module positioned on the compressor disc, the support module having a hollow groove suitable for the compressor moving blade to pass through, with a gap between the hollow groove and the compressor moving blade; a guide module disposed on the support module, suitable for moving axially along the compressor disc; and a cutting module disposed on the guide module, having a cutting end positioned directly above the gap during cutting, suitable for axial cutting along the compressor disc via the guide module. The support module of this invention positions the cutting module, eliminating the need for operators to hold an angle grinder. The guide module provides linear guidance for the cutting module, ensuring that the cutting groove cuts linearly along the compressor disc axis, preventing the cutting angle from wobbling due to unstable handling and avoiding accidental damage to the compressor disc.

An anastomosis assisting device for proximal aorta in coronary artery bypass grafting
PendingCN122123746AAvoid clampingavoid potential risksSurgical needlesBlood vesselsCoronary Artery BypassesAorta clamps
An auxiliary device for proximal aortic anastomosis in coronary artery bypass grafting (CABG) includes a puncture needle, a puncture cannula, a cutting cannula, and a ring compressor. The puncture cannula is fitted over the puncture needle, with a bulging ball at its tip and an annular groove at its tail end. The ring compressor is fitted over the puncture cannula and can slide axially; its tip has a notched compression ring with an inner diameter smaller than the outer diameter of the bulging ball. During puncture, after the aorta is penetrated, the ring compressor is pressed down, and the compression ring and bulging ball work together to clamp the puncture site, achieving a bloodless procedure. The cutting cannula is then pressed down, and the aortic wall within the compression ring is removed. The graft vessel is then anastomosed to the aorta, with the suture passing through the compression ring. After suturing, the ring compressor is rotated, and the suture exits through the notch. The entire device is then withdrawn, and the suture is tightened and knotted to complete the anastomosis. This invention avoids aortic clamping, eliminates the risk of plaque dislodgement, requires only a single port for anastomosis, and is simple to operate with reliable hemostasis.

This invention provides a method and system for processing book edge relief. The method includes: converting a preset book edge planar image into a three-dimensional depth map containing depth information; creating a three-dimensional relief model of the book edge based on the three-dimensional depth map; generating an engraving scheme based on the three-dimensional relief model, the engraving scheme including tool path, feed rate, step distance, and depth of cut; optimizing the engraving scheme according to the paper characteristics of the book; mechanically engraving the book edge according to the optimized engraving scheme; and inkjet coloring the mechanically engraved book edge to form an relief pattern with a three-dimensional visual effect. In this invention, by mechanically engraving the book edge, a book edge relief with controllable depth, sharp edges, and a smooth and delicate surface can be formed, which is beneficial for the accurate registration and color reproduction of subsequent inkjet printing, completely avoiding the defects of laser edge burning and insufficient layering of mechanical imprinting, and enabling the mass production of high-quality book edge decorations.
