    • A fluid injection valve has: a valve body that is provided with an opening portion at one axial end thereof and is for starting and stopping a supply of a fluid out of the opening portion; and an injection port plate having a plurality of injection ports that penetrate therethrough, the injection port plate being fixed on the one axial end of the valve body to form a fluid chamber between itself and the valve body to accumulate the fluid therein and to which at least a part of the injection ports opens. A circumferential surface of the fluid chamber recedes toward the injection ports so as to decrease a cross-sectional area of the fluid chamber that is taken along a radial direction of the injection port plate and to reserve a predetermined length of distance between itself and the injection ports.
    • 流体喷射阀具有:阀体,其在其一个轴向端部设置有开口部,并且用于启动和停止从所述开口部分流出的流体; 以及具有贯穿其中的多个注入口的注入口板,所述注入口板固定在所述阀体的一个轴向端部上,以在其本身和所述阀体之间形成流体室,以将流体积聚在其中, 至少一部分注入口打开。 流体室的圆周表面朝向喷射口退出,以减小流体室的沿着喷射孔板的径向截取的横截面面积,并且在其自身与喷射之间保留预定长度的距离 港口。

    • A radiographic apparatus is disclosed, which allows a biopsy needle or a drug injection needle to be run into a patient accurately and quickly. Once a needle entry point on a body surface of the patient and a target point in the patient are designated and inputted on the screen of a display monitor, the radiographic apparatus in this invention automatically displays, en block on the display monitor, a guideline linking the two points, intersection marks indicative of intersections of the guideline and CT images, and angles and length serving as a reference for determining a direction and depth of running the needle. The operator has only to run the needle to a required depth along the guideline and intersection marks in the direction indicated by the angles displayed. Thus, the biopsy needle or injection needle may be run into the patient accurately and quickly.
    • 公开了一种放射线照相设备,其允许活检针或药物注射针准确且快速地进入患者。 一旦在患者的身体表面上的针入口点和患者中的目标点被指定并输入到显示监视器的屏幕上,本发明的射线照相设备将自动显示在显示监视器上的指南链接 两点,指示指纹和CT图像的交点的交叉标记,以及用作确定针的运行方向和深度的参考的角度和长度。 操作人员只能沿着指导针将指针运行到所需的深度,并以所显示的角度指示的方向交叉。 因此,活检针或注射针可以准确而快速地进入患者。
