All-in one syringe assembly for blood draws and medicine delivery to patients

Abstract

A syringe assembly includes (i) a syringe with a cylindrical body, luer tip at a first end, finger grip at a second end and a cannula extending from the luer tip into the cylindrical body, and (ii) a plunger unit having an adapter portion, receiving cavity, finger grip and piston. A channel extends the length of the adapter portion to receive the cannula in one end and a variety of connectors, valves and/or syringes in a second end. The end of the channel accessible in the receiving cavity mates with or engages any number of commercially available valves, connectors and/or syringes while the luer tip similarly connects to any number of valves, catheters, connectors, etc., depending on the task being undertaken with the syringe assembly.

We claim: 
     
         1 . A syringe assembly comprising:
 a syringe having a cylindrical body with a luer at a first end, said luer having an exit opening and two ports in communication with an interior of said cylindrical body of said syringe so that said side ports may direct fluid in and out of said cylindrical body;   a plunger unit including an adapter portion and a receiving cavity, a first end of said adapter portion retaining a piston, said plunger unit insertable into a second end of said syringe and slidable within said cylindrical body during which said piston creates a fluid seal with an interior surface of said cylindrical body; and   a cannula secured at one end proximate said exit opening of said luer and extending into said piston and extendable into said channel as said plunger unit is inserted farther into said syringe.   
     
     
         2 . The syringe assembly of  claim 1  wherein said cylindrical body is pre-filled with a flush, medicament or other fluid. 
     
     
         3 . The syringe assembly of  claim 1  wherein said two ports are spaced 180° about said exit opening. 
     
     
         4 . The syringe assembly of  claim 1  wherein said two ports serve to decrease pull pressure related to said plunger. 
     
     
         5 . The syringe assembly of  claim 1  wherein said two ports serve to prevent cell damage to ingested blood fluids. 
     
     
         6 . The syringe assembly of  claim 1  wherein said two ports facilitate pre-filling said syringe. 
     
     
         7 . The syringe assembly of  claim 2  wherein said two ports facilitate pre-filling said syringe. 
     
     
         8 . A syringe assembly comprising:
 a syringe having a cylindrical body with a luer at a first end, said luer having an exit opening and two ports in communication with an interior of said cylindrical body of said syringe so that said side ports may direct fluid in and out of said cylindrical body;   a plunger unit including an adapter portion and a receiving cavity, a first end of said adapter portion retaining a piston, said plunger unit insertable into a second end of said syringe and slidable within said cylindrical body during which said piston creates a fluid seal with an interior surface of said cylindrical body, said adapter portion including a channel extending along its length to an opening at a bottom of said receiving cavity for insertion of an intermediary connector or valve; and   a cannula secured at one end proximate said exit opening of said luer and extending into said piston and extendable into said channel as said plunger unit is inserted farther into said syringe.   
     
     
         9 . The syringe assembly of  claim 8  wherein said cylindrical body is pre-filled with a flush, medicament or other fluid. 
     
     
         10 . The syringe assembly of  claim 8  wherein said two ports serve to decrease pull pressure related to said plunger. 
     
     
         11 . The syringe assembly of  claim 8  wherein said two ports serve to prevent cell damage to ingested blood fluids. 
     
     
         12 . The syringe assembly of  claim 8  wherein said two ports facilitate pre-filling said syringe. 
     
     
         13 . The syringe assembly of  claim 9  wherein said two ports facilitate pre-filling said syringe. 
     
     
         14 . A syringe assembly comprising:
 a syringe having a cylindrical body with a luer at a first end, said luer having an exit opening and two ports spaced thereabout in communication with an interior of said cylindrical body of said syringe;   a plunger unit including an adapter portion and a receiving cavity, a first end of said adapter portion retaining a piston, said plunger unit insertable into a second end of said syringe and slidable within said cylindrical body during which said piston creates a fluid seal with an interior surface of said cylindrical body, said adapter portion including a channel extending along its length to an opening at a bottom of said receiving cavity for insertion of an intermediary connector or valve; and   a cannula secured at one end proximate said exit opening of said luer and extending into said piston and extendable into said channel as said plunger unit is inserted farther into said syringe.   
     
     
         15 . The syringe assembly of  claim 13  wherein said cylindrical body is pre-filled with a flush, medicament or other fluid. 
     
     
         16 . The syringe assembly of  claim 13  wherein said two ports are spaced 180° about said exit opening. 
     
     
         17 . The syringe assembly of  claim 13  wherein said two ports serve to decrease pull pressure related to said plunger. 
     
     
         18 . The syringe assembly of  claim 13  wherein said two ports serve to prevent cell damage to ingested blood fluids. 
     
     
         19 . The syringe assembly of  claim 13  wherein said two ports facilitate pre-filling said syringe. 
     
     
         20 . The syringe assembly of  claim 14  wherein said two ports facilitate pre-filling said syringe. 
     
     
         20 . The syringe assembly of  claim 14  wherein said two ports facilitate pre-filling said syringe.
