Low profile pivoting joint infusion assembly
First Claim
1. A system for subcutaneous delivery of a therapeutic fluid from a remote vessel into the body of a patient, the system comprising:
- a generally tabular assembly having a generally straight elongated cannula extending from a generally flat bottom surface;
a rotatable joint for engagement with the generally tabular assembly, the rotatable joint having an elongated engagement arm, the elongated engagement arm having a near end and a removed end and a joint body engaged with and integral with the near end of the elongated engagement arm having an axial aligned first fluid channel therethrough, the first fluid channel extending at least partially through the joint body;
the rotatable joint further having a second interconnecting fluid channel for intersecting with the first axially aligned fluid channel and with a surface of the joint body forming a fluid port thereby;
wherein the generally tabular assembly is adapted to engage the rotatable joint so as to provide rotation of the elongated engagement arm in a plane, the plane including the cannula of the generally tabular assembly;
wherein the elongated engagement arm is moveable between a first position, generally vertical to the generally tabular assembly, wherein the axially aligned first fluid channel is along an axis defining the cannula, to a second position, approximately perpendicular to the first position, wherein the second interconnecting fluid channel is in fluid communication with the cannula.

Abstract
System for the subcutaneous delivery into the body of a patient of a fluid from a remote vessel. The system includes a main assembly and placement member with a needle. A delivery tube for carrying the fluid is attached at a near end to the remote reservoir or vessel. At removed end, the delivery tube has a needle for engagement with the main assembly. The main assembly includes a rotating member that when the rotating is perpendicular to the main assembly, it will accept the handle and needle for emplacement of the body onto a patient. After the handle and needle are removed, the delivery tube can be attached to the rotating member which can then be rotated down to a position along to and adjacent the skin of the patient. This provides for a flush mounted infusion device.

18. A system for subcutaneous delivery of a therapeutic fluid from a remote vessel into the body of a patient, the system comprising:
-
a generally tabular assembly having a generally straight elongated cannula extending from a generally flat bottom surface; a rotatable joint for engagement with the generally tabular assembly, the rotatable joint having an elongated engagement arm, the elongated engagement arm having a near end and a removed end and a joint body engaged with and integral with the near end of the elongated engagement arm having an axial aligned first fluid channel therethrough, the first fluid channel extending at least partially through the joint body; the joint body further having a second interconnecting fluid channel for intersecting with the first axially aligned fluid channel and with a surface of the joint body forming a fluid port thereby; wherein the generally tabular assembly is adapted to engage the rotatable joint so as to provide rotation of the elongated engagement arm in a plane, the plane including the cannula of the generally tabular assembly; wherein the elongated engagement arm is moveable between a first position, generally vertical to the generally tabular assembly, wherein the axially aligned first fluid channel is along an axis defining the cannula, to a second position, approximately perpendicular to the first position, wherein the second interconnecting fluid channel is in fluid communication with the cannula; further including a fluid connector removably engageable with the elongated engagement arm and engageable with a remote source of therapeutic fluid, wherein the fluid connector is adapted to releasably engage the elongated engagement arm, when the elongated engagement arm is out of the second position; wherein the fluid connector and the generally tabular assembly include cooperating means to releasably engage the fluid connector to the generally tabular assembly when the fluid connector is engaged with the elongated engagement arm and rotating joint is in the second position; and further including a handle assembly having an emplacement needle, the emplacement needle engageable with the axially aligned first fluid channel of the elongated engagement arm. - View Dependent Claims (19, 20)
