Abstract
A system for injecting includes a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof. The system also includes a stopper member disposed in the syringe interior. The system further includes a plunger member coupled to the stopper member. The plunger member includes a rotatable member configured to insert the stopper member distally in the syringe interior relative to the syringe body with rotation of the rotatable member. The plunger member further includes a proximal portion proximal of the rotatable member configured to be moved distally to also insert the stopper member distally in the syringe interior relative to the syringe body to eject about microliters of fluid from the syringe interior.
Claims18
A system for injecting, comprising:
- a syringe body having proximal and distal ends, a syringe interior, and a syringe flange at the proximal end thereof;
- a stopper member disposed in the syringe interior;
- a finger flange coupled to the syringe flange;
- a rotatable member disposed on the finger flange, and
- a plunger member coupled to the stopper member, wherein the plunger member comprises an external stop proximal of the rotatable member configured to be moved distally relative to the rotatable member to further insert the plunger member and the stopper member coupled distally in the syringe interior relative to the syringe body,
- wherein the rotatable member has an opening through which the plunger member is disposed, and wherein the rotatable member is configured to travel along a longitudinal axis of the plunger member relative to the syringe body with rotation of the rotatable member.
