    • A syringe includes a body and a plunger disposed therein. The body includes a nozzle formed therein and at least one hub member connected thereto or integrally formed thereon for holding an end of a connector tube. The connector tube includes two ends, each end preferably being connected to a respective hub member to retain the connector tube in contact with the syringe. Preferably, the syringe and the connector tube are packaged in a pre-connected condition for ease of use by the customer. Furthermore, flexible inlet tubing for connection to a syringe for filling the syringe with contrast media, for example, is described. The inlet tubing permits filling of the syringe from either a bag or a bottle and may remain attached to the syringe so that it forms at least a part of the connection to the patient. In addition, an apparatus for facilitating the purge of air from a connector tube that will ultimately be connected between a syringe and a patient is described. The apparatus includes a purging tube connected to the distal end of the connector tubing from the syringe. The purging tube includes a venting cap at its distal end. A flow inhibitor is positioned under the venting cap to cooperate with the venting cap by discouraging the discharge of fluid from the distal end of the purging tube while permitting the discharge of air therefrom.
    • 注射器包括主体和设置在其中的柱塞。 主体包括形成在其中的喷嘴和与其连接或一体地形成在其上的至少一个毂构件,用于保持连接器管的端部。 连接器管包括两个端部,每个端部优选地连接到相应的毂部件,以将连接器管保持与注射器接触。 优选地,注射器和连接管被包装在预连接状态中,以便客户易于使用。 此外,描述了用于连接到注射器的柔性入口管,用于例如用造影剂填充注射器。 入口管允许从袋或瓶中填充注射器,并且可以保持附接到注射器,使得其形成与患者的连接的至少一部分。 此外,描述了一种便于从最终连接在注射器和患者之间的连接管吹扫空气的装置。 该装置包括从注射器连接到连接管的远端的清洗管。 吹扫管在其远端包括通气盖。 流动抑制剂位于排气盖下面,以与通气帽配合,通过阻止从清洗管的远端排出流体,同时允许排出空气。
