A method for preparing drug in hemisphere-shaped dosage form. A high molecular weight solution containing the drug is prepared, and the solution is then dropped on a base material. The interface phenomena between the solution and different base materials makes the drop of high molecular weight solution containing the drug form a hemisphere-shape. After solidifying by cross-link or evaporation, the drug in hemisphere-shaped dosage form is obtained. The advantages of the preparation method are a simple and fast process, and simple operation. Applications of the method to prepare a drug in hemisphere-shaped dosage form are also provided.

An electrospinning manufacture for drug carriers is disclosed. The method comprises a preliminary step mixing a predetermined drug, an alginate, and a saline to obtain a mixture; an electric field establishing step providing a collection plate and an emitter filled with divalent cation agent and the mixture individually, wherein an electric field is applied to the collection plate and the emitter to form a voltage therebetween; and an electrospinning step sequentially dropping the mixture from the emitter into the divalent cation agent filled in the collection plate via the driving of the electric field, triggering a crosslinking-gelating reaction between the divalent cation and the alginate, wherein a plurality of gel particles is produced for a coating of the predetermined drug presenting a drug carrier performance.
摘要:
The present invention includes a carrying frame with two connecting ends for pivotally connected to a supporting frame for mounting the display, and two pivots are respectively mounted at the positions where the connecting ends of the carrying frame are pivotally connected with the supporting frame, wherein one pivot is penetrated through a hook flange washer and a positioning flange washer, wherein the hook flange washer has plural protruding portions located at one side of the edge thereof, and the positioning flange washer correspondingly has plural bulges located at one side of the edge thereof for forming a position-limiting trough to reject with the protruding portion, and the other pivot is penetrated through plural positioning washers and at least a plate type washer, so that when the carrying frame has a turning, the required torsion can be provided by the rejection between the protruding portion and the position-limiting trough.
