    • An electro-spray delivery device for delivering a stream of charged micro-droplets of a conductive fluid, and which a capillary tube having a proximal end in fluid communication with a source of conductive fluid and a distal end opposite the proximal end. The device also includes a solid guide wire coaxially disposed at least partially within the capillary tube to form an annular passage therein, and which has a distal tip projecting beyond the distal end of the capillary tube. At least one of the capillary tube and guide wire is conductive and in electrical communication with a high-voltage source to electrically charge the conductive fluid flowing through the annular passage and wetting the distal tip of the guide wire. The electrospray delivery device further includes a grounding electrode that is located a predetermined distance from the distal tip of the guide wire and which is in electrical communication with a source of ground. A voltage differential between the charged fluid and the grounding electrode draws the charged fluid away from the distal end of the capillary tube to form a cone jet about the end face of the distal tip discharging a stream of charged micro-droplets.
    • 一种用于传送导电流体的带电微滴流的电喷射递送装置,其中毛细管具有与导电流体源流体连通的近端和与近端相对的远端。 该装置还包括同轴地设置在毛细管内的实心导丝,以在其中形成环形通道,并且具有突出超出毛细管远端的远端尖端。 毛细管和导丝中的至少一个是导电的并且与高压源电连通以对流过环形通道的导电流体进行电荷并润湿导丝的远端。 电喷雾输送装置还包括接地电极,该接地电极位于与导丝的远端顶部预定距离处,并且与接地源电连通。 带电流体和接地电极之间的电压差使得带电流体远离毛细管的远端,以形成围绕远侧末端的端面排出带电微滴流的锥形射流。
