Abstract
A method for rotatable selection of sites for cannulation of a subcutaneous vascular access vessel comprises the step of providing a template defining an opening for a plurality of zones, each of the plurality of zones configured for receiving a plurality of simultaneous cannulations accessing the vascular access vessel. The outer surface of the template is marked, the marking defining each of the plurality of zones for use as cannulation sites along the vascular access vessel. The template is positioned on the skin of the patient adjacent the subcutaneous vascular access vessel such that the opening aligns with the vascular access vessel, and the marking is used for selecting a first zone for a cannulation site into the vascular access vessel such that the cannulation site in the first zone is spaced from and not adjacent to a second zone used for cannulation immediately previously to the first zone.
