Mixing vial

Abstract

Various implementations include a mixing vial system. The system includes a hypodermic syringe and a mixing vial. The mixing vial includes a vessel, a stopper, and a dislodgeable plug. The vessel includes an open end, a closed end, and a side wall. A hollow interior chamber is defined by the side wall and the closed end. The open end defines a neck. The stopper includes an open proximal end, a closed distal end, and a stopper side wall. The closed distal end and the stopper side wall define a hollow interior chamber. The stopper is positioned in a sealing relationship within the neck. The dislodgeable plug is positioned in and sealing the open proximal end of the stopper. The closed distal end of the stopper is penetrable by a needle of the hypodermic syringe to dislodge the dislodgeable plug to effect mixing of contents of the stopper and the vessel.

1 .- 13 . (canceled) 
     
     
         14 . A mixing vial system, the system comprising:
 a hypodermic syringe comprising:
 a barrel, and 
 a needle having a distal end and a proximal end coupled to the barrel; and 
   a mixing vial comprising:
 a vessel including an open end, a closed end opposite and spaced apart from the open end, and at least one side wall extending from the open end to the closed end, wherein a hollow interior chamber is defined by the at least one side wall and the closed end, wherein the open end defines a neck having a distal open end and a proximal open end; 
 a stopper including an open proximal end, a closed distal end, and a stopper side wall extending from the open proximal end to the closed distal end, wherein the closed distal end and the stopper side wall are a single piece and define a hollow interior chamber, the stopper being positioned in a sealing relationship within the neck; and 
 a dislodgeable plug positioned in and sealing the open proximal end of the hollow interior chamber of the stopper, 
 wherein the closed distal end of the stopper is penetrable by the distal end of the needle of the hypodermic syringe to fully dislodge the entire dislodgeable plug to effect mixing of contents of the interior chamber of the stopper and the interior chamber of the vessel. 
   
     
     
         15 . The system of  claim 14 , wherein the closed end and the at least one side wall of the vessel of the mixing vial are formed as a single piece. 
     
     
         16 . The system of  claim 14 , wherein the stopper comprises an elastomeric material. 
     
     
         17 . The system of  claim 16 , wherein the stopper is made entirely of the elastomeric material. 
     
     
         18 . The system of  claim 14 , wherein the contents of the interior chamber of the vessel comprises an anesthetic drug, and the contents of the interior chamber of the stopper comprises a buffering reagent. 
     
     
         19 . The system of  claim 14 , wherein the neck of the vessel has a largest diameter and the at least one side wall has a largest diameter, wherein the largest diameter of the at least one side wall is greater than the largest diameter of the neck. 
     
     
         20 . The system of  claim 14 , wherein the closed distal end of the stopper includes a radially outwardly extending annular flange. 
     
     
         21 . The system of  claim 14 , wherein the mixing vial further comprises a metal clip for retaining the stopper within the neck. 
     
     
         22 . The system of  claim 14 , wherein the vessel comprises glass. 
     
     
         23 . The system of  claim 14 , wherein the dislodgeable plug includes a strike plate for preventing needle penetration. 
     
     
         24 . The system of  claim 14 , wherein the needle of the hypodermic syringe is in fluid communication with the barrel such that mixed contents of the interior chamber of the stopper and the interior chamber of the vessel can flow from the mixing vial, through the needle, and into the barrel such that the mixed contents of the interior chamber of the stopper and the interior chamber of the vessel are retained within the barrel.
