Infusion set for a fluid pump

A tubing set for coupling a fluid delivery device into fluid communication with a cannula assembly having a first locking element disposed in a fixed position with respect to a cannula, the tubing set further including:

• a length of tubing having a first end and a second end;
• a hub for retaining a replaceable reservoir in a barrel in a pump housing in the fluid delivery device, the barrel including a longitudinal axis, the hub comprising:
• (1) a first end including a first end face disposed transverse to a hub axis, the first end face including a port disposed along the hub axis, the port having the first end of the length of tubing affixed thereto for passage of fluid from the reservoir, the first end face having formed therein a grip to facilitate rotation of the hub about the hub axis, and
• (2) a second end including a first male element for engaging with a corresponding female element on the reservoir to lock the hub to the reservoir and a second male element for engaging with a corresponding element of the pump housing to retain the reservoir in the barrel when (a) the hub is placed in the pump housing so that the hub axis corresponds with the barrel axis, and (b) the hub is rotated;
• and
• an infusion flap coupled to the second end of the length of tubing for connecting to the cannula assembly, the infusion flap including:
• a tubing needle,
• a second locking element for engaging the first locking element of the cannula assembly, and
• a lift tab for disconnecting the infusion flap from the cannula assembly,
• wherein coupling of the first and second locking elements requires initial mating of the infusion flap and cannula assembly followed by locking through rotation of the infusion flap with respect to the cannula assembly.
