Biological fluid filtration system
A biological fluid filtration system for scanning a biological fluid so as to filter potentially undesirable constituents from the biological fluid for therapeutic or diagnostic purposes. The biological fluid filtration system generally includes a fluid receiving device adapted to receive a biological fluid. A valve including an inlet, a first outlet, and a second outlet is fluidly connected to the fluid receiving device. The biological fluid within the fluid receiving device is scanned by a scanner to produce scanned data relating to the biological fluid. A control unit in communication with the scanner and the valve receives the scanned data and controls the valve based on the scanned data. The valve is controlled to direct the biological fluid through either the first or second outlet of the valve depending upon the constituents of the biological fluid identified by the control unit.
1. A biological fluid filtration system, comprising:
a fluid receiving device adapted to receive a biological fluid;
a valve comprising an inlet, a first outlet, and a second outlet, wherein the inlet of the valve is fluidly connected to the fluid receiving device;
a scanner configured to scan the biological fluid within the fluid receiving device to produce a scanned data relating to the biological fluid within the fluid receiving device; wherein the scanner is an optical scanner comprising a digital holographic microscope; and
a control unit in communication with the scanner and the valve, wherein the control unit is configured to receive the scanned data from the scanner, wherein the control unit is configured to compare the scanned data to a reference data, wherein the reference data comprises one or more characteristics of healthy cell types other than a selected healthy cell type subset, wherein the healthy cell type subset is comprised of a white blood cell, and wherein the control unit is configured to control the valve based on the scanned data from the scanner;
wherein the control unit is configured to control the valve to (a) direct the biological fluid through the first outlet if the control unit determines that the scanned data indicates a presence of the healthy cell types within the biological fluid or (b) direct the biological fluid through the second outlet if the control unit determines that the scanned data does not indicate the presence of the healthy cell types within the biological fluid, such that the selected healthy cell type subset is directed through the second outlet.
2. The biological fluid filtration system of claim 1 , wherein the healthy cell type subset is comprised of a natural killer cell.
3. The biological fluid filtration system of claim 1 , wherein the healthy cell type subset is comprised of a macrophage.
4. The biological fluid filtration system of claim 1 , wherein the biological fluid is comprised of a leukapheresis extract.
5. A method of filtering a biological fluid using the biological fluid filtration system of claim 1 , comprising the steps of: receiving the biological fluid by the fluid receiving device; scanning the biological fluid within the fluid receiving device by the scanner; comparing the scanned data with the reference data by the control unit; directing the biological fluid through the first outlet if the control unit determines that the scanned data indicates the presence of the healthy cell types within the biological fluid; and directing the biological fluid through the second outlet if the control unit determines that the scanned data does not indicate the presence of the healthy cell types within the biological fluid.
6. A biological fluid filtration system, comprising:
a fluid receiving device adapted to receive a biological fluid;
a valve comprising an inlet, a first outlet, and a second outlet, wherein the inlet of the valve is fluidly connected to the fluid receiving device;
a scanner configured to scan the biological fluid within the fluid receiving device to produce a scanned data relating to the biological fluid within the fluid receiving device; wherein the scanner is an optical scanner comprising a digital holographic microscope; and
a control unit in communication with the scanner and the valve, wherein the control unit is configured to receive the scanned data from the scanner, wherein the control unit is configured to compare the scanned data to a reference data, wherein the reference data comprises one or more characteristics of healthy cell types other than a selected healthy cell type subset, wherein the healthy cell type subset is comprised of a T-cell, and wherein the control unit is configured to control the valve based on the scanned data from the scanner; wherein the control unit is configured to control the valve to (a) direct the biological fluid through the first outlet if the control unit determines that the scanned data indicates a presence of the healthy cell types within the biological fluid or (b) direct the biological fluid through the second outlet if the control unit determines that the scanned data does not indicate the presence of the healthy cell types within the biological fluid, such that the selected healthy cell type subset is directed through the second outlet.
7. The biological fluid filtration system of claim 6 , wherein the biological fluid is comprised of a leukapheresis extract.
8. A method of filtering a biological fluid using the biological fluid filtration system of claim 6 , comprising the steps of: receiving the biological fluid by the fluid receiving device; scanning the biological fluid within the fluid receiving device by the scanner; comparing the scanned data with the reference data by the control unit; directing the biological fluid through the first outlet if the control unit determines that the scanned data indicates the presence of the heathy cell types within the biological fluid; and directing the biological fluid through the second outlet if the control unit determines that the scanned data does not indicate the presence of the healthy cell types within the biological fluid.
