SYSTEMS AND METHODS FOR AUTOMATED AIR REMOVAL IN PRODUCTS COMPRISING BIOLOGICAL FLUIDS

摘要

Methods and systems are provided automatically removing air from a collection container for a blood product. The system comprises a disposable flow circuit including a tubing in fluid communication with the collection container and a durable hardware component. A programmable controller operates the pump in a first/forward direction to flow the target product into the collection container; determines that substantially all the target product has been pumped into the collection container; and operates the pump in the first/forward direction to pump a chase volume of air into the collection container along with any target product remaining in the tubing. In one embodiment, after the chase volume of air is pumped into the collection container, the controller operates the pump in a second/reverse direction for removing air from the collection container, and stops operation of the pump when the amount of air removed from the collection container is substantially equal to the residual volume of air.

主权项

1. A method for automatically controlling a system for separating biological fluids to remove air from a collection container into which a target product has been flowed, the system comprising a disposable flow circuit including a tubing in fluid communication with the collection container and a durable hardware component including a pump for engaging the tubing to flow fluid therethrough and a programmable controller for operating the pump, the method comprising:
a) the programmable controller operating the pump in a first, forward direction to flow the target product into the collection container; b) the programmable controller determining that substantially all the target has been pumped into the collection container; and c) the programmable controller operating the pump in the first, forward direction to pump a chase volume of air into the collection container along with any target product remaining in the tubing.
