Abstract
A fluid dispensing device having a barrel having a lumen for containing a fluid therein and a flexible structure extending from the barrel. A plunger is axially slidable within the lumen to dispense fluid from the barrel, the plunger having a first set of grooves spaced apart a first distance and a second set of grooves spaced apart a second distance. The flexible structure includes a flexible arm extending transversely with respect to the barrel and configured to engage the grooves.
Claims20
A fluid dispensing device comprising:
- a barrel having a lumen for containing a fluid therein and a flexible structure extending from the barrel;
- and
- a plunger axially slidable within the lumen to dispense fluid from the barrel, the plunger having a first set of grooves spaced apart a first distance and a second set of grooves spaced apart a second distance, and the flexible structure including at least one flexible arm extending transversely with respect to the barrel and positioned to engage either the first set of grooves or the second set of grooves.
A fluid dispensing device comprising:
- a barrel having a lumen for containing a fluid therein and a deflectable structure extending from the barrel;
- and
- a plunger axially slidable within the lumen to dispense fluid from the barrel, the plunger having a longitudinal axis and a set of grooves extending longitudinally along an outer surface,
- the deflectable structure extending transversely with respect to the barrel and positioned to engage the set of grooves, the deflectable structure deflecting in a transverse direction to disengage from the grooves.
A fluid dispensing device comprising:
- a barrel having a lumen for containing a fluid therein and a flange at a proximal portion of the barrel;
- a plunger axially slidable within the lumen to dispense fluid from the barrel, the plunger having a longitudinal axis and a set of grooves extending longitudinally along an outer surface, and
- a deflectable structure mountable to the proximal portion of the barrel and engageable with an underside of the flange, the deflectable structure extending transversely with respect to the barrel and positioned to engage the set of grooves, the deflectable structure being external of the barrel and exposed.
