Abstract
An apparatus comprises a plunger able to fit in a cartridge or syringe. The plunger includes an outer portion and a deflection portion. The outer portion is able to engage the body of the cartridge or syringe. The outer portion is operable to apply a first radial force to the cartridge or syringe. The deflection portion is positioned within the outer portion and is movable between a locked position and an unlocked position. The deflection portion in the unlocked position causes the outer portion to apply a second radial force to the cartridge or syringe
Claims21
An apparatus comprising a plunger configured to fit in a cartridge or syringe, the plunger apparatus comprising:
- a first plunger portion comprising:
- an open end;
- a deflection portion opposite the open end and including an opening;
- and
- an outer, circumferential, contact portion configured to contact an inner surface of the cartridge or syringe;
- and
- a second plunger portion configured for receipt within the first plunger portion and comprising:
- a central plug;
- at least one outer wall configured to contact an inner surface of the outer contact portion of the first plunger portion;
- and
- at least one channel for allowing fluid to flow through the second plunger portion to contact the deflection portion of the first plunger portion,
- wherein the deflection portion is movable from a locked position, in which the central plug plugs the opening, to an unlocked position, in which the central plug is separated from the opening to allow fluid flow through the opening.
