Title:
VACUUM DRYING PROCESS USED FOR MANUFACTURING DIALYZER
Document Type and Number:
WIPO Patent Application WO2004093936
Kind Code:
A3
Abstract:
A method of sterilizing and drying a dialyzer or other device, wherein a vacuum drying phase is interrupted by interspersed pulses of air or other gas. The pulses lessen the evaporative cooling effect, to thereby reduce differential shrinkage that can structurally damage the dialyzer.
