Systems And Methods For Ensuring Proper Tubing Installation For Fluid Processing Systems

摘要

A fluid separation system is provided for separating a plasma-containing fluid into separated plasma and a concentrated fluid. The system cooperates with a fluid flow circuit including a fluid separation chamber and a plasma outlet line associated therewith for removing separated plasma from the fluid separation chamber. The system includes an optical sensor assembly that receives a portion of the plasma outlet line when the fluid flow circuit has been associated with the fluid separation system. To ensure proper installation of the plasma outlet line, the optical sensor assembly compares light received by its light detector to a baseline value, which is indicative of the amount of light received by the light detector before the plasma outlet line has been installed. The amount of received light being equal to or less than a selected percentage of the baseline value indicates that the plasma outlet line has been properly installed.

1. A fluid processing system configured to cooperate with a fluid flow circuit, the fluid processing system comprising:
an optical sensor assembly configured to receive a portion of the fluid flow circuit and comprising
a light source configured to emit a light, anda light detector configured to receive a portion of the light emitted by the light source and to produce an output indicative of the amount of received light; and a controller configured to receive the output from the light detector and programmed to determine whether said portion of the fluid flow circuit is properly received by the optical sensor assembly by
comparing the output from the light detector to a baseline value that is indicative of the amount of light from the light source that is received by the light detector in the absence of said portion of the fluid flow circuit, anddetermining that said portion of the fluid flow circuit is properly received by the optical sensor assembly if the output from the light detector is equal to or less than a selected percentage of the baseline value.
