Abstract: A porous bionic skull repairing material includes a polymer material, whose structure is consistent with that of a human skull. The surface layers of the porous bionic skull repairing material are dense layers which are composed of non-degradable or degradable polymer materials and has blind holes having an asymmetric structure, and the inner layer of the porous bionic skull repairing material is a loose layer which has a porous structure. The repairing material can be molded by adopting a mixed mould pressing method or a 3D printing method, simulates a bone structure, with two dense sides and a loose middle, of a human skull to the greatest extent.

Abstract: A method for preparing a degradable drug-loaded microsphere for embolization and a product obtained therefrom, includes the steps of: dissolving a degradable material in an organic solvent, then adding a drug and mixing well to form a suspension or solution; then pouring the drug-containing suspension or solution into an aqueous solution of polyvinyl alcohol, stirring, and thereafter adding water twice for dilution, to prepare the degradable drug-loaded microsphere. The microsphere prepared by the present invention has the advantages of having a controllable particle size, a high drug loading capacity, and a regular spherical shape, being convenient for sieve sizing and accurate particle-size indication, and being accurately targeted to an embolized blood vessel, and the like, and thus has a good application prospect in interventional embolization therapy.

Abstract: An automatic bread slice-toasting oven comprises a case, a toasting chamber, a guide rail form toasting shelf, an electrical transmission mechanism and a timing control circuit. A push rod provided with push claws is provided beneath the toasting shelf, the push claws are hinged to the two ends of the push rod via pivot pins respectively, the push rod is connected to the transmission mechanism. The motor rotates in the positive and negative directions by the controlling of the timing control circuit so as to reciprocate the push rod, so that the front claw on the push rod pushes the toasted bread slice out of the toasting chamber and the rear claw pushes a bread slice to be toasted into the toasting chamber. The toasting can be carried out automatically, continuously and alternatively by setting the time period of toasting with safety and convenience, thus increasing the efficiency of toasting greatly and ensuring the quality of the toasted bread slice.
