    • A tube device for forming a fistula is constructed in such a way that the tube device is composed of a metallic guide wire, a small diameter tube to which the guide wire can be inserted in its center, a medium diameter tube covering the outer periphery of the small diameter tube, a medium-large diameter tube covering the outer periphery of the small diameter tube and having an outer diameter larger than the medium diameter tube, a large diameter tube covering the outer periphery of the small diameter tube and having an outer diameter larger than the medium-large diameter tube, a large diameter drainage tube covering the outer periphery of the small diameter tube and having an outer diameter equal to that of the large diameter tube, and an extra large diameter tube covering the outer periphery of the large diameter drainage tube. An outer diameter of each tip portion of the small diameter tube, medium diameter tube, medium-large diameter tube and large diameter tube is gradually reduced towards ends thereof to be taper-shaped. These tubes are exchanged and inserted in the order of their diameters, i.e. from small diameter to large diameter, by means of a guide wire. The extra large diameter tube necessary for the insertion of the endscope can be inserted in a short time with an extreme safety since the tapered surface of the tip portion of the tube applies the pressure to the liver tissue to expand it gradually.
    • 用于形成瘘管的管装置被构造成使得管装置由金属导丝,导丝可以插入其中心的小直径管,覆盖外围的中径管 小直径管,覆盖小直径管的外周并具有比中等直径管大的外径的中大直径管,覆盖小直径管的外周的大直径管,具有外径 大于中大直径管,大直径排水管覆盖小直径管的外周,外径等于大直径管的外径,外径大的管覆盖大直径管的外周 直径排水管。 小直径管,中径管,中大直径管和大直径管的每个末端部分的外径朝向其端部逐渐减小为锥形。 这些管子通过导丝以其直径,即从小直径到大直径的顺序交换和插入。 由于管的尖端部分的锥面向肝组织施加压力以逐渐扩张,所以能够在极短的时间内插入用于插入内镜的特大直径的管。

    • A cooking oven includes a box-like casing defining a heating chamber wherein food in placed. A rear plate of the casing has a recess projecting outward, a number of suction holes cut in the bottom of the recess, and a number of discharge holes cut in sections located above and below the recess. A cover is fixed to the outer surface of the rear plate to define a storing chamber. In the storing chamber are arranged a fan for drawing air in the heating chamber into the storing chamber and discharging the air into the heating chamber, and a heater for heating the sucked air. The cover has a first air-directing section for directing part of the hot air from the fan in a direction parallel to the top plate of the casing, and a second air-directing section for directing part of the hot air in a direction different from the direction of the hot air directed by the first air-directing section.
    • 烹饪炉包括限定加热室的盒状壳体,其中放置食物。 壳体的后板具有向外突出的凹部,在凹部的底部切割的多个吸入孔以及位于凹部上方和下方的多个排出孔。 盖子固定到后板的外表面以限定储存室。 在储存室中设置有用于将加热室内的空气吸入储存室并将空气排放到加热室中的风扇和用于加热吸入空气的加热器。 所述盖具有第一导风部分,用于沿着平行于所述壳体的顶板的方向引导来自所述风扇的部分热空气,以及第二导风部分,用于将部分热空气沿不同于 由第一导风部分引导的热空气的方向。
