Pivoting joint infusion system with steal

1. An infusion system for delivery of a therapeutic fluid from a remote source into a patient's body comprising;

a main infusion unit having a housing, a cannula with an injection channel, said cannula attached at an underside of said main infusion unit, a first fluid channel in communication with said cannula, and a rotating joint member receiving chamber;

a rotating joint member having a central fluid channel, a needle emplacement channel, and a fluid infusion channel, all of said channels intersecting within a central portion of said rotating joint member, said rotating joint member adapted to be received within and rotatable within said chamber and;

a fluid connector assembly having a fluid delivery channel, said fluid connector assembly attachable at an end of said rotating joint member such that said fluid delivery channel aligns with and is in communication with said central fluid channel of said rotating joint member, said fluid connector assembly attachable at a remote end to a delivery tube attached to said remote source of said therapeutic fluid;

wherein said rotating joint member rotatable from a first emplacement position

whereby an emplacement needle may be extended through said needle emplacement channel of said rotating joint member and through said injection channel of said cannula to subcutaneously pierce said patient

to a second delivery position after said emplacement needle has been withdrawn from said patient and said fluid connector assembly has been attached at said near end of said rotating joint member, said second delivery position aligning said fluid infusion channel with said injection channel of said cannula to deliver said therapeutic fluid to said patient.

2. The infusion system of claim 1 , wherein the main infusion unit further comprises a recess in said housing to receive and retain said rotating joint member when said rotating joint member is rotated to a third position, the third position for preventing flow of therapeutic fluid to the patient's body.

3. The infusion system of claim 2 , wherein the main infusion unit further includes a cover adapted to protect an opening to said central fluid channel in said rotating joint member when said rotating joint member is rotated to the third position.

4. The infusion system of claim 1 , wherein said rotating joint member upon removal of said fluid connector assembly is rotatable to a third position, said third position misaligning said fluid infusion channel with said first fluid channel of said main infusion unit to substantially prevent delivery of said therapeutic fluid to said patient.

5. The infusion system of claim 4 , wherein the central portion of said rotating joint member is a ball joint.

6. The infusion system of claim 5 , wherein said rotating joint member includes ears attached to the ball joint.

7. The infusion system of claim 1 , further including fluid sealing member cooperating with said fluid connector assembly and said rotating joint member to provide a fluid tight seal when the fluid connector assembly is engaged with the rotating joint member.

8. The infusion system of claim 1 , further including means to releasably lock said fluid connector assembly to said rotating joint member when said fluid connector assembly is in said second delivery position.

9. The infusion system of claim 1 , wherein the main infusion unit has walls defining a cutout and the fluid connector assembly has walls dimensioned for receipt into the cutout when the fluid connector assembly is in the second delivery position.

10. The infusion system of claim 1 , wherein the main infusion unit, rotating joint member, and fluid connector assembly are all septumless.
