Clip Syringe

Abstract

A single use pre-filled delivery device is disclosed having a deformable container including a side wall having an inside surface defining a chamber for retaining fluid, a clip element, and a locking element. The deformable container further includes a closed proximal end and an open distal end including a male luer tip having a passageway therethrough providing fluid communication with the chamber. The male luer tip may be removably connectable to a female luer connection of a vascular access device. The clip element includes a distal end, proximal end, and a pivot located between the distal end and the proximal end of the clip element for collapsing the deformable container to drive fluid out of the chamber by movement of the proximal end towards the distal end. The pivot may be a hinge, which may be in the form of a living hinge. The deformable container may be attached to the clip element. The locking element may be disposed on the clip element. A method of administering a fluid to a vascular access device using a single use pre-filled delivery device as described herein is also disclosed.

What is claimed is: 
     
         1 . A single use pre-filled delivery device comprising:
 a deformable container including a side wall having an inside surface defining a chamber for retaining fluid, a closed proximal end and an open distal end including a male luer tip having a passageway therethrough providing fluid communication with said chamber; said male luer tip removably connectable to a female luer connection of a vascular access device; and   a clip element for collapsing the deformable container having a distal end and proximal end comprising a pivot located between the distal end and the proximal end for driving fluid out of said chamber by movement of the proximal end towards the distal end, the clip element comprising a distal portion and a proximal portion, said deformable container being attached to the clip element; and   a locking element having a racheting mechanism having a plurality of teeth and a catch.   
     
     
         2 . The single use pre-filled delivery device of  claim 1 , wherein the catch is disposed on the proximal end of the clip element and the plurality of teeth is disposed on the distal end of the clip element. 
     
     
         3 . The single use pre-filled delivery device of  claim 1 , wherein the catch is disposed on the distal end of the clip element and the plurality of teeth is disposed on the proximal end of the clip element. 
     
     
         4 . The single use pre-filled delivery device of  claim 1 , wherein the locking element is arranged to be manually activated by a user after the catch engages to one or more of the plurality of teeth. 
     
     
         5 . The single use pre-filled delivery device of  claim 1 , wherein the locking element minimizes reflux of solution in the passageway. 
     
     
         6 . The single use pre-filled delivery device of  claim 1 , wherein the vascular access device is a syringe, extension set, intravenous set, stop cock, tubing, high pressure extension tubing, or needleless connector. 
     
     
         7 . The single use pre-filled delivery device of  claim 1 , further comprising a pre-selected amount of sterile fluid in the chamber. 
     
     
         8 . The single use pre-filled delivery device of  claim 7 , wherein the pre-selected amount of fluid in the chamber is from 0.5 ml to 10 ml. 
     
     
         9 . The single use pre-filled delivery device of  claim 8 , wherein the fluid comprises a sterile flush solution. 
     
     
         10 . The single use pre-filled delivery device of  claim 9 , wherein the flush solution is saline, heparin, water or a combination thereof. 
     
     
         11 . The single use pre-filled delivery device of  claim 8 , wherein the fluid comprises a medicament or drug. 
     
     
         12 . The single use pre-filled delivery device of  claim 1 , wherein the deformable container is made of thermoplastic elastomers, polyolefin, polyester or other injection moldable or formable resin. 
     
     
         13 . The single use pre-filled delivery device of  claim 1 , further comprising a tip cap releasably connected to the male luer tip. 
     
     
         14 . A method of administering a fluid to a vascular access device comprising the steps of:
 (a) providing a single use pre-filled delivery device of  claim 1 ;   (b) providing a vascular access device having a proximal end, a distal end and a passageway therethrough, said proximal end having a female luer tip in fluid communication with said passageway;   (c) placing said distal end of said vascular access device in a blood vessel of a patient;   (d) engaging said male luer tip of said deformable container with said female luer tip of said vascular access device;   (e) applying force to the clip element to engage the locking element such that the catch engages to one or more of the plurality of teeth; and   (g) disengaging said male luer tip of said deformable container from said female luer tip of said vascular access device.
