Slotted syringe

Abstract

A syringe is disclosed. The syringe may include a syringe body, a first slot formed in the syringe body, a first sleeve covering the first slot, a thumb grip including a first slot guide disposed in the first slot, the thumb grip shaped to slide from a first position near the distal end of the syringe body toward a second position near the proximal end of the syringe body, and a plunger disposed in the fluid chamber of the syringe body. The plunger is configured to move towards the proximal end of the syringe body in response to pressure applied by a user to the thumb grip and includes a first plunger slot guide.

         12 . A dermal filler syringe comprising:
 a syringe body with a fluid chamber, the syringe body having a proximal end and a distal end, with an extrusion opening at the proximal end;   a first slot formed in the syringe body, starting near the proximal end of the syringe body and ending near the distal end of the syringe body;   a slidable thumb grip, the thumb grip including a first slot guide disposed in the first slot, the thumb grip shaped to slide from a first position near the distal end of the syringe body toward a second position near the proximal end of the syringe body; and   a plunger disposed in the fluid chamber of the syringe body, the plunger configured to move towards the proximal end of the syringe body in response to pressure applied by a user to the thumb grip, the plunger including a first plunger slot guide disposed in the first slot.   
     
     
         13 . The syringe of  claim 12 , further comprising:
 a second slot formed in the syringe body, beginning near the proximal end of the syringe body and ending near the distal end of the syringe body;   wherein the thumb grip further includes a second slot guide disposed in the second slot.   
     
     
         14 . The syringe of  claim 12 , wherein the first slot passes through the syringe body, from an outer surface forming an outer circumference of the syringe body through an inner surface forming the fluid chamber. 
     
     
         15 . The syringe of  claim 12 , wherein:
 the plunger is attached to the thumb grip.   
     
     
         16 . The syringe of  claim 12 , further comprising:
 an end cap disposed at the distal end of the syringe body.   
     
     
         17 . The syringe of  claim 12 , further comprising:
 a finger grip disposed on the syringe body near the proximal end of the syringe body.   
     
     
         18 . The syringe of  claim 12 , wherein:
 the first slot extends to the distal end of the syringe body.
