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;   a fluid de-accelerator device positioned within said luer;   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 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.   
     
     
         2 . The syringe assembly of  claim 1  wherein said cannula is recessed from said luer tip opening in a range of about 0.15 inches to about 0.35 inches. 
     
     
         3 . The syringe assembly of  claim 1  wherein said receiving cavity has a depth in a range of about 1 inch to 1.5 inches. 
     
     
         4 . The syringe assembly of  claim 1  wherein said fluid de-accelerator device has a double helix design or a single circuit design. 
     
     
         5 . A syringe assembly comprising:
 a syringe having a cylindrical body with a luer at a first end, said luer having an exit opening;   a fluid de-accelerator device positioned within said luer, said fluid de-accelerator in the form of a plug with fluid pathways about an outer surface thereof;   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 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.   
     
     
         6 . The syringe assembly of  claim 5  wherein said cannula is recessed from said luer tip opening in a range of about 0.15 inches to about 0.35 inches. 
     
     
         7 . The syringe assembly of  claim 5  wherein said receiving cavity has a depth in a range of about 1 inch to 1.5 inches. 
     
     
         8 . The syringe assembly of  claim 5  wherein said fluid de-accelerator device has a double helix design or a single circuit design. 
     
     
         9 . A syringe assembly comprising:
 a syringe having a cylindrical body with a luer at a first end, said luer having an exit opening;   means for de-accelerating fluid as it passes through said luer;   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 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.   
     
     
         10 . The syringe assembly of  claim 9  wherein said means for de-accelerating fluid as it passes through said luer is a plug with fluid pathways about an outer surface thereof. 
     
     
         11 . The syringe assembly of  claim 9  wherein said means for de-accelerating fluid as it passes through said luer has a double helix design or a single circuit design. 
     
     
         12 . The syringe assembly of  claim 10  wherein said means for de-accelerating fluid as it passes through said luer has a double helix design or a single circuit design.
