Abstract
This invention relates to therapeutic infusion assemblies, more specifically a device for the subcutaneous delivery of a fluid from a remote source. Applicant provides a base assembly which has a fluid channel therein and a cannula extending vertically downward from a flat bottom. A fluid connector member which receives a fluid bearing line from the remote fluid source and the fluid connector member pivotably and removably connects to the base member. The manner of connection is “hinged” allowing the fluid connector to move from a non-use position by rotation downward to a used position. In the use position a fluid channel in the fluid connector will connect with a fluid channel in the base to provide fluid to the cannula and to the patient.
