  • PRECISION SYRINGE PLUNGER WITH SEPARATELY MANUFACTURED AND IRREVERSIBLY COUPLED PLUNGER ARM AND PLUNGER ROD
    Publication number: 20220023545
    Abstract: A precision syringe plunger includes a plunger rod and a separately manufactured plunger arm. The plunger rod includes a base formed at a proximal end of the plunger rod and a first interference fit connector formed below the base. The plunger rod is configured to extend longitudinally into a syringe barrel. The plunger arm includes a second interference fit connector formed at a proximal end of the plunger arm. The second interference fit connector is configured to be irreversibly coupled to the first interference fit connector so that the plunger arm extends longitudinally along an outer surface of the syringe barrel. The plunger arm further includes a distally located projection. The projection is configured to receive an applied force that causes an entirety of the syringe plunger to move relative to the syringe barrel so that the plunger rod is actuated through a portion of the syringe barrel.

  • Precision syringe
    Patent number: 11167091
    Abstract: A precision syringe includes a syringe barrel and plunger that has a base, an internal portion, and an external portion. The internal portion of the plunger extends longitudinally into the syringe barrel. The internal portion has a first end coupled to the base and a second end that is configured to push fluid out of and/or suction fluid into the syringe barrel. The external portion extends longitudinally along an outer surface of the syringe barrel. The external portion has a first end coupled to the base and a second end that is configured to receive an applied force that causes the plunger to move relative to the syringe barrel so that the second end of the internal portion is actuated through a portion of the syringe barrel (e.g., to dispense fluid from or suction fluid into the syringe barrel).
