Abstract
An embodiment in accordance with the present invention provides an integrated syringe-device which can store a volume of fluid for infusion, can connect via an air-tight connector to another device (such as a luer connector), can flush fluid through the connector into the other device, and can deliver a cap that forms an air-tight closure to the device connector.
Claims13
An apparatus for infusing liquid and sealing an indwelling medical device comprising:
- a syringe body having an outer wall defining a lumen extending therethrough for holding an infusing liquid and further including a proximal end and a distal end and wherein the outer wall defines an opening at the distal end of the syringe body;
- a plunger slidably disposed within the lumen of the syringe, such that the plunger slides from the proximal end of the syringe body to the distal end of the syringe body;
- a first notch defined by the outer wall of the syringe body and positioned proximate of the opening at the distal end of the syringe body;
- a pinch release ring having a finger which couples with the first notch and a wing to provide leverage to remove the finger from the first notch;
- a cap defining an opening through which the infusing liquid can travel, disposed within the opening at the distal end of the syringe body configured to couple to an end of the indwelling medical device and wherein the cap defines a second notch with which the finger of the pinch release ring can couple;
- and
- a plunger seal disposed at a proximal end of the plunger, and configured to be separable from the proximal end of the plunger and coupleable to the cap, such that the cap is sealed when coupled to the plunger seal.
