Abstract: A nebulizer system includes a bottle that has a bottle mouth on top thereof and stores liquid therein, a heater device that is connectable to the bottle mouth, and a nebulizer adapter that is connectable to the heater device. The bottle includes a dip tube that is dipped into the liquid stored therein. An upper end portion of the dip tube is disposed inside a circumferential wall of the bottle mouth with a clearance communicating between an interior and an exterior of the bottle via the bottle mouth. The nebulizer adapter includes a nozzle member that has an orifice for injecting gas, and an aerosol-forming member in a corresponding position with the orifice, the aerosol-forming member sucking up the liquid in the bottle via the dip tube and heater device by a stream of gas injected from the orifice, and generating fine aerosol from the sucked liquid.

Abstract: A biomedical article made of alumina ceramics including an aluminum oxide having a purity of not less than 99.95% and unavoidable impurities as remainder. The alumina ceramics contains no sintering agent. The alumina ceramics has no irregularities in the crystal grain size, and has a strength necessary for biomedical article, and have a crystal grain size of less than 1.0 &mgr;m to assure excellent slidability.

Abstract: A living body-supporting member having a surface layer with multiple pores regularly arranged therein, in which the porous portions constituting the living body-supporting member are made of ceramics giving no harm to a human body. And a method to perforate multiple pores in a green sheet made of the ceramics, to laminate the green sheets so that pores communicate with each other, and to fire it. The living body-supporting member is coupled with the bone, and there is no risk that it may drop from the supporting portion. Even if the substrate is composed of ceramics, the substrate and the surface layer can be integrally coupled with each other, thereby there is no risk that both of them are separated. Furthermore, according to the above method, the pore shapes of the porous body can be preliminarily designed so that pores communicate with each other while being displaced for every certain depth, and it can be accurately controlled in the production thereof.
