Abstract
A syringe assembly for use with an infusion pump having a drive piston. The syringe assembly comprises a substantially hollow syringe housing and a plunger axially movable within the syringe housing to dispense a fluid therefrom. The plunger has a body with a portion thereof configured to engage a radially elastic member associated with the drive piston such that the plunger is releasably axially secured relative to the drive piston.
Claims20
A syringe assembly for use with an infusion pump having a drive piston, the syringe assembly comprising:
- a substantially hollow syringe housing;
- a plunger axially movable within the syringe housing to expel a fluid therefrom, the plunger having a body with a portion configured to engage a radially elastic member associated with the drive piston such that the plunger is releasably axially secured relative to the drive piston.
An infusion pump assembly comprising:
- an insulin pump including a drive piston having a radially elastic member associated therewith;
- and
- a syringe assembly including a substantially hollow syringe housing and a plunger axially movable within the syringe housing to expel a fluid therefrom, the plunger having a body with a portion configured to engage the radially elastic member associated with the drive piston such that the plunger is releasably axially secured relative to the drive piston.
An infusion pump assembly comprising:
- an insulin pump including a drive piston with a first annular groove;
- a syringe assembly including a substantially hollow syringe housing and a plunger axially movable within the syringe housing to expel a fluid therefrom, the plunger having a body engagable with the drive piston and including a second annular groove;
- and
- a radially elastic member positional within the first and second grooves to releasably, axially secure the plunger relative to the drive piston.
