20100217206 | Luer-Snap Connection and Luer-Snap Syringe - Syringes having a snap-fit mechanism for attaching a needle hub to a syringe barrel in a snap-fit relationship and packaged medical device comprising a syringe with a snap-fit mechanism and a needle hub mare provided. An exemplary syringe includes a barrel with a collar and a rotatable arm which allows connection of a needle hub to the barrel in a snap-fit relationship. Additional features of the collar and rotatable arm may also permit disconnection of the needle hub from the barrel without the use of relative rotation of the needle hub and barrel. In a specific configuration, the syringe utilizes a torsional snap-fit element to connect the needle hub to the barrel in a snap-fit rotation. In a more specific configuration, the syringe utilizes a collar with differing interior surfaces which permit snap-fit assembly and disassembly of the needle and the barrel. | 08-26-2010 |
20110046559 | Syringe Assembly Having a Flexible or Slidable Flange - A syringe assembly having a flexible and/or slidable flange is provided, wherein in a pre-use or packaged state, the flange is positioned substantially parallel to the barrel of the syringe resulting in a syringe assembly having a smaller packaging footprint. The smaller packaging footprint allows for reduced storage space of the syringe assembly. Upon removal from the packaging and/or storage space, the flange can be slid and locked into place such that it extends in a perpendicular direction with respect to a longitudinal axis of the syringe barrel to allow for traditional operation of the syringe. | 02-24-2011 |
20110046560 | Magnifying Collapsed Plunger Rod - A syringe assembly having a collapsible or pivotable plunger rod with magnification properties is provided. In a pre-use or packaged state, the plunger rod is positioned substantially parallel to the barrel of the syringe resulting in a syringe assembly having a reduced length and a smaller packaging footprint. The smaller packaging footprint allows for reduced storage space of the syringe assembly. Upon removal from the packaging and/or storage space, the plunger rod can be slid or pivoted toward the proximal end of the syringe barrel and locked into place such that the syringe is ready for use. The plunger rod can be shaped to provide magnification to the syringe barrel indicia and/or contents. Alternatively, a separate magnification member can be associated with the plunger rod and/or secured about the syringe barrel. | 02-24-2011 |
20110046569 | Syringe Having a Collapsible Plunger Rod - A syringe assembly includes a syringe barrel having an exterior surface, an inside surface defining a chamber, an open proximal end, a distal end, and an outlet disposed adjacent the distal end in fluid communication with the chamber; and a plunger assembly disposed at least partially within the syringe barrel. The plunger assembly includes an elongated plunger rod and a plunger head. The elongated plunger rod is associated with the plunger head to move the plunger head within the chamber of the syringe barrel through an injection cycle. The plunger rod is adapted to move from a collapsed position extending alongside the exterior surface of the syringe barrel to an extended position engaging the plunger head to move the plunger head through the injection cycle. | 02-24-2011 |
20110224610 | Medical Device Including an Air Evacuation System - Medical device assemblies capable of aspirating liquid into a syringe barrel or other medical devices while evacuating any air from the syringe are described. An exemplary medical device includes a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within either the stopper or the plunger rod. Described is a medical device including a syringe barrel, plunger rod and stopper assembly having an air permeable and liquid impermeable porous portion and structure for forming a vacuum within chamber between the stopper and plunger rod wherein the plunger rod includes a sealing edge and is moveable relative to the stopper. Exemplary medical devices may include a vent for allowing air that permeates through the porous portion to escape to atmosphere. Methods for aspirating a syringe barrel with a liquid are also provided. | 09-15-2011 |
20110224611 | MEDICAL DEVICE INCLUDING AN AIR EVACUATION SYSTEM - Medical device assemblies capable of aspirating liquid into a syringe barrel or other medical devices while evacuating any air from the syringe are described.
