Abstract:
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 vertically at an underside of said main infusion unit, [a first fluid channel in communication with said cannula,] and a rotating joint member receiving surface; a rotating joint member having a fluid channel, a separate needle emplacement channel, and a separate fluid infusion channel generally perpendicular to the fluid channel and the needle emplacement channel, said rotating joint member adapted to be received upon and rotatable with said joint member receiving surface; and a fluid connector assembly having a fluid delivery channel, said fluid connector assembly removably attachable to an end of said rotating joint member such that said fluid delivery channel aligns with and is in fluid communication with said 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; whereby an emplacement needle may be extended when said rotating joint member is vertical, through said fluid channel and said needle emplacement channel of said rotating joint member and through said injection channel of said cannula to subcutaneously pierce said patient; wherein said rotating joint member is rotatable about 90° in an axis perpendicular to said cannula from a first vertical emplacement position to a second horizontal delivery position after said emplacement needle has been withdrawn from said patient and said fluid connector assembly has been attached to said rotating joint member, said second delivery position aligning said fluid infusion channel such that it is in fluid communication with said injection channel of said cannula to deliver said therapeutic fluid to said patient; wherein said rotating joint member is rotatable to a third position, the third position for preventing flow of therapeutic fluid to the patient's body or the flow of fluids from the patient's body out of the rotating joint member.
