    • A method of manufacturing a dental prosthesis, including: (a) a step of preparing a substrate of the dental prosthesis that is constituted by a dental molding material; (b) a step of forming a back coating layer on at least a part of a surface of the substrate, by using a first porcelain that is constituted principally by ceramic; (c) a step of forming a casting mold such that the substrate is disposed in the casting mold and such that a void is provided on a surface of the back coating layer; and (d) a step of forming a cast coating layer on at least a part of a surface of the back coating layer, by pouring a second porcelain into the void at a casting temperature. The second porcelain is constituted principally by ceramic whose composition is different from that of the ceramic of the first porcelain that viscosity of the second porcelain at the casting temperature is lower than that of the first porcelain. Also disclosed are a kit and a dental porcelain set that are used for manufacturing the dental prosthesis.
    • 一种制造牙科假体的方法,包括:(a)制备由牙科模制材料构成的牙科假体的基底的步骤; (b)通过使用主要由陶瓷构成的第一瓷,在所述基材的表面的至少一部分上形成背涂层的步骤; (c)形成铸模,使得基板设置在铸模中,并且在背涂层的表面上设置空隙的步骤; 和(d)通过在铸造温度下将第二种陶瓷浇注到空隙中,在背涂层的表面的至少一部分上形成流延涂层的步骤。 第二瓷主要由陶瓷构成,其组成与第一瓷的陶瓷不同,铸造温度下第二瓷的粘度低于第一瓷的粘度。 还公开了用于制造牙科假体的试剂盒和牙科瓷器组。

    • An instrument for introducing a catheter into a blood vessel includes an inner needle portion having an inner needle, and a dilator portion having a dilator, the latter including first and second insertion portions. The first insertion portion, which has a comparatively small diameter and a length no less than the distance from a patient's skin to the blood vessel wall, is formed at the tip of the dilator from which a cutting edge at the tip of the inner needle is capable of protruding. The second insertion portion, which has a comparatively large diameter and a length no less than the above length, is smoothly connected to the first insertion portion by a tapered intermediate segment. Also provided is a sheath portion through which a catheter is capable of being passed under liquid-tight conditions.
    • 用于将导管引入血管的仪器包括具有内针的内针部分和具有扩张器的扩张器部分,后者包括第一和第二插入部分。 具有相对较小直径和长度不小于从患者皮肤到血管壁的距离的第一插入部分形成在扩张器的尖端处,内针的尖端处的切割边缘是 能突出。 具有比较大的直径和长度不小于上述长度的第二插入部分通过锥形中间段平滑地连接到第一插入部分。 还提供了护套部分,导管能够在液体密封条件下通过该鞘部分。
