A syringe, comprising: a syringe body comprising a cylindrical main body portion, a conical portion connected to the cylindrical main body portion, and a discharge outlet connected to the conical portion;a two-part medical connector connected to the end of the discharge outlet and comprising a first part having a body defining a lumen for high pressure fluid flow through the medical connector and comprising a luer member and an annular member connected to the body, the luer member comprising external engagement structure and the annular member comprising internal and external engagement structure, wherein each of the external engagement structure of the luer member and the internal and external engagement structure of the annular member are in parallel alignment, the luer member further comprising a luer proximal end and a luer distal end and the annular member further comprising a proximal wall, an annular wall having a proximal end connected to the proximal wall and a distal end defining an annular opening, the luer proximal end of the luer member being integrally formed with the proximal wall of the annular member and the luer distal end of the luer member being recessed within the annular member and proximal to the distal end of the annular member; anda flange formed on and extending circumferentially about the body of the first part of the medical connector and located rearward of the annular member;wherein the body of the first part is connected to a second part having a body defining a second annular member, the second annular member comprising internal and external engagement structure, wherein said external engagement structure of the second annular member mates with the internal engagement structure of the annular member of the body of the first part and said internal engagement structure of the second annular member mates with the external engagement structure of the luer member of the body of the first part, said first and second parts capable of delivering fluid from the syringe to a patient when mated. 6. The syringe of claim 5 wherein the internal and external engagement structure on the annular member of the body of the first part comprises threads. 7. The syringe of claim 5 wherein the luer member of the body of the first part comprises either a male luer member or a female luer member. 8. The syringe of claim 5 wherein the external engagement structure on the luer member of the body of the first part comprises threads. 9. A two-part medical connector, comprising: a first part and a second part,the first part comprising:a luer member having an external engagement structure; anda first annular member having an internal engagement structure and an external engagement structure,wherein each of the external engagement structure of the luer member and the internal and external engagement structure of the first annular member are concentrically aligned,the second part comprising: a second annular member having an internal engagement structure and an external engagement structure,wherein the second part is connectable to the first part to form a fluid delivery path by engaging at least one of the external engagement structure of the luer member, the external engagement structure of the first annular member, and the internal engagement structure of the second annular member. 10. The two-part medical connector of claim 9, wherein the first part and the second part are connectable by mating the external engagement structure of the second annular member of the second part with the internal engagement structure of the first annular member of the first part and mating the internal engagement structure of the second part with the external engagement structure of the luer member of the first part. 11. The two-part medical connector of claim 9, wherein each of the external engagement structure of the luer member and the internal and external engagement structure of the first annular member of the first part are of a different size. 12.
