Material Reservoir Centered Or Clamped In Syringe By Slidable Component Patents (Class 604/234)
  • Patent number: 9821119
    Abstract: The invention provides a syringe assembly comprising a syringe barrel having an inside surface defining a chamber, an open proximal end, and a distal end having an opening therethrough. An elongated plunger rod extends between a first end and a second end, with a cap or guard disposed on the first end of the plunger rod. A plunger head extends within the chamber of the syringe barrel, and is adapted for slidable movement within the syringe barrel between the proximal end and the distal end, with the second end of the plunger rod connected with the plunger head through a pivotable connection. The plunger rod is adapted to pivot with respect to the plunger head between a first position in which the guard is adjacent the distal end of the syringe barrel and a second position in which the plunger rod is in general axial alignment with the syringe barrel, and is further adapted for axial movement so as to cause sliding movement of the plunger head through the syringe barrel to expel contents thereof.

With the cartridge (10) fitted, the tongue (48) is straightened, and a spring clip (50) holds the cartridge (10) in position. A plunger (38) can then be depressed, though a guide (42), to drive the bung (18) forward and make the injection.

  • Patent number: 8298194
    Abstract: A refillable injection device (1) having a dose setting mechanism with a dose setting member (4) and a dose rod (11). The dose setting member and the dose rod engage during normal operation of the injection device, and they do not engage during change of cartridge. The dose setting member and the dose rod need to be moved into engagement when a new cartridge is inserted in the injection device. Thereby there is a risk that stress is build-up in the piston rod. In order to prevent this, the cartridge holder is operatively connected to the dose rod in such a manner that when a cartridge is being inserted in the cartridge holder, the dose rod is caused to move along with the piston rod in an axial direction, at least while the dose setting member and the dose rod are moved into engagement.

Alternatively, a release mechanism could be used so that the vial may be removed from the medication delivery pen. In addition, the vial retainer includes an opening for receiving the vial defined by a pair of flexible snap wings.

  • Patent number: 6045537
    Abstract: A syringe for injection of doses of a medicine from an exchangeable cartridge has a housing comprising a cartridge holder and a dosing mechanism by which a dose is set and injected by successively advancing a piston rod to press a piston into the cartridge. The dosing mechanism comprises a threaded spindle and a nut member cooperating with the spindle. A dose is set by relative rotation of the spindle and nut member whereby the nut member is moved along the spindle. The position of the nut member on the spindle defines how far the piston rod is advanced. The spindle and the nut are locked against relative rotation when the dosing mechanism is not operated to set a dose. Access to the cartridge holder is obtained by opening a lid connected to the housing and coupled to the dosing mechanism in such a way that the locking of the nut element in its position on the spindle is released when the lid is opened, and the opening movement of the lid is transmitted to a piston rod retraction mechanism.

  • Patent number: 6024728
    Abstract: A veterinary syringe with a dosing device for administering medications in different preselectable amounts, comprises a piston rod which projects into a syringe cylinder by a piston provided at a first end of the piston rod and which is supported at a handle at its other end by an actuating lever which is fastened to the other end so as to be swivelable. The piston rod is supported so as to be displaceable longitudinally in a holder which is rigidly connected with the handle. A dosing device is provided between the holder on one side and the piston rod on the other side. At least two longitudinal grooves are arranged parallel to one another and which have different lengths compared with one another are distributed along the outer circumference of the piston rod. An engagement member is provided which is arranged so as to be rotatable about the piston rod and can be moved into one of the grooves.
