Fluid transfer port information system
First Claim
1. A method of associating a specific fluid transfer port with a given fluid transfer event of fluid to a patient from a parenteral fluid delivery device, the method comprising:
- transmitting a conductive fluid transfer signal from the parenteral fluid delivery device to a patient associated identifier by capacitively coupling the conductive fluid transfer signal to the fluid infused to the patient from the parenteral fluid delivery device, wherein the patient associated identifier is configured to use a patient'"'"'s body as a signal conduction medium upon establishment of a fluid transfer connection between the parenteral fluid delivery device and the patient, and wherein the parenteral delivery device is coupled to the patient using a plurality of fluid transfer ports; and
determining which of the plurality of fluid transfer ports is employed for the given fluid transfer event based on a parameter of the conductive fluid transfer signal; and
wherein the parameter varies with respect to distance traveled by the fluid transfer signal.

Abstract
Methods are provided for associating a specific one of two or more distinct fluid transfer ports of a patient with a given fluid transfer event of fluid from a parenteral fluid delivery device. Aspects of the methods include establishing a fluid transfer connection between the parenteral fluid delivery device and the patient via one of the two or more distinct fluid transfer ports and transmitting a fluid transfer signal between the parenteral fluid delivery device and a patient associated identifier using the patient'"'"'s body as a signal conduction medium. Association may result in identification of the fluid transfer port that will be, is being or has been employed for the given fluid transfer event. Also provided are systems for practicing methods of the invention.
