摘要： An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger having a proximal end, a distal end and a stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel.for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The plunger includes anti-reflux structure for minimizing stopper deflection when fluid has been delivered from the chamber and the stopper is being forced against the distal end of the chamber.

摘要： An I.V. flush syringe assembly includes a barrel having an inside surface defining a chamber for retaining fluid, an open proximal end and a distal end with a passageway therethrough in fluid communication with the chamber. An elongate plunger havind a proximal end, a distal end and a flexible stopper is slidably positioned in fluid-tight engagement with the inside surface of the barrel for drawing fluid into and out of the chamber by movement of the stopper relative to the barrel. The barrel includes anti-reflux structure for holding said stopper in a partially deflected position after has been delivered from the chamber and the stopper is being force against the distal end of the chamber.

摘要： The present invention is generally directed to a drug delivery device for selecting and dispensing a number of user variable doses of a medicament. The device comprises a housing (10) having a tubular portion (12) with an inner thread, a piston rod (30) having a threaded portion (31) and a distal end, and a bearing (140) having a distal face and a proximal face. The bearing (140) comprises a retaining stem (142) protruding from the proximal face. The piston rod (30) comprises a distal portion having an outer diameter which is smaller than the inner diameter of the inner thread of the tubular portion (12) and comprising at its distal end at least one retaining clip (33, 33′) engaging the retaining stem (142). The axial length of the tubular portion (12) is smaller than or equal to the axial distance between the proximal face of the bearing disc (141) and the distal end of the threaded portion (31) of the piston rod (30). During manufacturing of the device, the retaining clip (33, 33′) engages the retaining stem (142) prior to the inner thread of the tubular portion (12) engages with the threaded portion (31) of the piston rod (30).
