Integrated syringe device with self-capping connector

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.

What is claimed is: 
     
         1 . A method for locking an indwelling medical device comprising:
 pulling a plunger back from a distal most position within a barrel of a syringe to a proximal position within the barrel of the syringe to transfer lock solution from a reservoir within the plunger to the barrel of the syringe;   depressing the plunger to a first predetermined point within the barrel of the syringe to purge air from the syringe barrel;   coupling the syringe to the indwelling medical device via an end cap disposed at a distal end of the syringe;   depressing the plunger to a second predetermined point within the barrel of the syringe to flush the lock solution into the indwelling medical device; and   disengaging the syringe from the end cap such that the end cap remains coupled to the catheter.   
     
     
         2 . The method of  claim 1 , further comprising pushing a sealing member into the end cap.
