Title:
TANGENTIAL FLOW FILTER SYSTEM FOR FILTRATION OF MATERIALS FROM BIOLOGIC FLUIDS
Document Type and Number:
Japanese Patent JP2020124526
Kind Code:
A
Abstract:
To provide a system for withdrawing a volume of fluid comprising cerebrospinal fluid (CSF) from a CSF-containing space at a first flow rate.SOLUTION: A system comprises: a first filtration system including a first tangential flow filter for filtering a volume of fluid into a first permeate and a first retentate, the first filtration system operating according to a first set of parameters; a second filtration system including a second tangential flow filter in fluid connection with the first filtration system, and for filtering the first retentate into a second permeate and a second retentate, the second filtration system operating according to a second set of parameters; and a combiner in fluid connection with the first filtration system and the second filtration system, the combiner for combining the first permeate and the second permeate to form a combined permeate. The system is further configured to return the combined permeate from the combiner to a CFS-containing space of a subject at a second flow rate and updates at least one of the first set of operation parameters and the second set of operation parameters on the basis of a characteristic measured by a sensor responsive to determining that the measured characteristic exceeds a predetermined threshold.SELECTED DRAWING: Figure 1
