Syringe extrusion accessory

Abstract

Described herein are syringe extrusion accessories comprising: a handle operatively coupled to an attachment portion configured to attach to a syringe; and at least one prawl operatively coupled to the handle and configured to engage with a plunger of the syringe, wherein the syringe extrusion accessory is configured to transfer a substantially perpendicular force applied to the handle to an axial force to push the plunger and extrude a product from the syringe.

We claim: 
     
         1 . A syringe extrusion accessory comprising:
 a handle operatively coupled to an attachment portion configured to attach to a syringe; and   at least one prawl operatively coupled to the handle and configured to engage with a plunger of the syringe,   wherein the syringe extrusion accessory is configured to transfer a substantially perpendicular force applied to the handle to an axial force to push the plunger and extrude a product from the syringe.   
     
     
         2 . The syringe extrusion accessory of  claim 1 , wherein the at least one prawl includes at least one claw. 
     
     
         3 . The syringe extrusion accessory of  claim 1 , wherein the prawl has a sinusoidal shape. 
     
     
         4 . The syringe extrusion accessory of  claim 1 , wherein the handle is coupled to the attachment portion through a hinge. 
     
     
         5 . The syringe extrusion accessory of  claim 1 , wherein the prawl is coupled to the handle through a hinge. 
     
     
         6 . The syringe extrusion accessory of  claim 5 , wherein the prawl is further attached to the handle with a spring. 
     
     
         7 . The syringe extrusion accessory of  claim 6 , wherein the spring is a compression spring. 
     
     
         8 . The syringe extrusion accessory of  claim 1 , wherein the substantially perpendicular force is between about 1 degree and about 20 degrees perpendicular to the syringe. 
     
     
         9 . The syringe extrusion accessory of  claim 1 , wherein the attachment portion is configured to attach to a flange portion of the syringe. 
     
     
         10 . The syringe extrusion accessory of  claim 1 , wherein the handle includes a depression configured to apply force from at least one finger. 
     
     
         11 . A method of extruding a product from a syringe, the method comprising:
 applying a substantially perpendicular force to an accessory associated with the syringe; and   extruding the product from the syringe,   wherein the accessory includes a handle operatively coupled to an attachment portion configured to attach to a syringe; and at least one prawl operatively coupled to the handle and configured to engage with a plunger of the syringe.   
     
     
         12 . The method of  claim 11 , wherein the accessory is configured to transfer a substantially perpendicular force applied to the handle to an axial force to push the plunger and extrude the product from the syringe. 
     
     
         13 . The method of  claim 11 , wherein the substantially perpendicular force is applied to a depression on the handle. 
     
     
         14 . The method of  claim 11 , wherein the method further comprises attaching the accessory to the syringe. 
     
     
         15 . The method of  claim 14 , wherein the accessory is configured to attach to a flange on the syringe. 
     
     
         16 . The method of  claim 11 , wherein the substantially perpendicular force is between about 1 degree and about 20 degrees perpendicular to the syringe. 
     
     
         17 . The method of  claim 11 , wherein the at least one prawl includes at least one claw. 
     
     
         18 . The method of  claim 11 , wherein the prawl has a sinusoidal shape. 
     
     
         19 . The method of  claim 11 , wherein the handle is coupled to the attachment portion through a hinge. 
     
     
         20 . The method of  claim 11 , wherein the prawl is coupled to the handle through a hinge. 
     
     
         21 . The method of  claim 20 , wherein the prawl is further attached to the handle with a spring. 
     
     
         22 . The method of  claim 21 , wherein the spring is a compression spring.
