The pushbutton stopcock assembly has a sleeve with outer ports, a body portion with inner ports, and a pushbutton to actuate a rotation of the body portion. Each outer port of the sleeve connects to a fluid passageway for the introduction of fluids, and each inner port is in fluid connection with the other inner ports. In this manner, fluids flow and travel from fluid passageways, through the outer ports, and through the inner ports. The body portion has a first end with a spring and a second end with a cam. The pushbutton abuts the second end portion of the body portion, such that depressing the pushbutton engages the cam to be cooperative with a complementary cam within the sleeve so as to rotate the body portion a set amount. Each set amount of rotation corresponds to a particular alignment of the outer ports and inner ports.

1. A pushbutton stopcock assembly, comprising: a sleeve, being cylindrical and having a plurality of outer ports, each outer port extending outward from said sleeve and being connectable to fluid passageways, each outer port being arranged perpendicular to at least one adjacent outer port;a body portion, being cylindrical and received within an interior of said sleeve, said body portion having a spring affixed on a first end portion thereof and a cam means on a second end portion, said first end portion having a diameter smaller than other portions of said body portion, said body portion having a plurality of inner ports corresponding to said plurality of outer ports, said inner ports being in fluid communication with each other and being arranged perpendicular to at least one adjacent inner port, each inner port extending partially through said body portion; anda pushbutton, being connected to said body portion at said second end portion thereof,wherein said cam means is cooperative with a complementary cam means within said sleeve so as to rotate said body portion about an axis aligned with said sleeve,wherein said pushbutton moves between an extended position to a depressed position, said spring returning said pushbutton from said depressed position to said extended position, said pushbutton engaging said cam means when moving from said extended position to said depressed position such that said cam means and said complementary cam means rotate said body portion a set amount and direction about said axis aligned with said sleeve, andwherein alignment between said inner ports on said body portion and said outer ports on said sleeve corresponds to the set amount of rotation of said body portion. 2. The pushbutton stopcock assembly of claim 1, wherein an outer port of said sleeve has a Luer lock at a distal end thereof. 3. The pushbutton stopcock assembly of claim 1, wherein said plurality of outer ports comprise a first outer port, a second outer port, and a third outer port, and wherein said plurality of inner ports comprise a first inner port, and a second inner port. 4. The pushbutton stopcock assembly of claim 3, wherein said first inner port corresponds to said first outer port and said second inner port corresponds to said second outer port in alignment after rotation of said set amount of said body portion, wherein said first inner port corresponds to said second outer port and said second inner port corresponds to a stop in misalignment after a subsequent rotation of said set amount of said body portion,wherein said first inner port corresponds to said stop and said second inner port corresponds to said third outer port in misalignment after another subsequent rotation of said set amount of said body portion,wherein said first inner port corresponds to said third outer port and said second inner port corresponds to said first outer port in alignment after still another subsequent rotation of said set amount of said body portion, andwherein another set amount of rotation returns said first inner port to said first outer port and said second inner port to said second outer port. 5. The pushbutton stopcock assembly of claim 1, wherein said plurality of outer ports comprise a first outer port, a second outer port, and a third outer port, and wherein said plurality of inner ports comprise a first inner port, a second inner port, and a third inner port. 6. The pushbutton stopcock assembly of claim 5, wherein said first inner port corresponds to said first outer port, said second inner port corresponds to said second outer port, said third inner port corresponds to said third outer port in alignment after rotation of said set amount of said body portion, wherein said first inner port corresponds to said second outer port, said second inner port corresponds to a stop, said third inner port corresponds to said first outer port in alignment after a subsequent rotation of said set amount of said body portion,wherein said first inner port corresponds to said stop, said second inner port corresponds to said third outer port, said third inner port corresponds to second outer port in alignment after another subsequent rotation of said set amount of said body portion,wherein said first inner port corresponds to said third outer port, said second inner port corresponds to said first outer port, said third inner port corresponds to said stop in alignment after still another subsequent rotation of said set amount of said body portion, andwherein another set amount of rotation returns said first inner port to said first outer port, said second inner port to said second outer port, and said third inner port to said third outer port. 7. The pushbutton stopcock assembly of claim 1, wherein said cam means comprises a plurality of engagement means, each engagement means being arranged for 90 degree rotation of said body portion for each actuation of said pushbutton, wherein said complementary cam means comprises a plurality of protrusions within said sleeve engaging respective engagement means, andwherein each protrusion engages a respective engagement means to rotate said body portion a set amount as said pushbutton moves from said extended position to said depressed position in a set direction. 8. The pushbutton stopcock assembly of claim 7, wherein each protrusion engages an adjacent engagement means, when said spring returns said pushbutton to said extended position.
