Estimating the term…
An optical detection assembly for monitoring a biological fluid in a vessel includes two fluid-adjustment structures, which are spaced apart and configured to receive at least a portion of a biological fluid-containing vessel therebetween. A light source (which may be associated with one of the fluid-adjustment structures) is configured to emit light through a thickness of the biological fluid in the vessel, while a light detector (which may be associated with the other one of the fluid-adjustment structures) is configured to receive at least a portion of the light from the light source after it has passed through the biological fluid in the vessel. At least a portion of at least one of the fluid-adjustment structures is configured to move with respect to at least a portion of the other one so as to change the thickness of the biological fluid in the monitored portion of the vessel.
(canceled)
The optical detection assembly of claim 22, wherein the first and second fluid-adjustment structures are configured such that movement of said at least a portion of said at least one of the first and second fluid-adjustment structures with respect to the other one of the first and second fluid-adjustment structures changes a dimension of said at least a portion of the vessel.
The optical detection assembly of claim 22, further comprising
The optical detection assembly of claim 22, wherein the light source is configured as a broadband light source.
The optical detection assembly of claim 22, wherein the light source is configured to emit light having a single wavelength.
The optical detection assembly of claim 22, wherein said at least a portion of only one of the first and second fluid-adjustment structures is movable and said at least a portion of the other one of the first and second fluid-adjustment structures is stationary.
8-9. (canceled)
The optical detection assembly of claim 22, wherein the first and second fluid-adjustment structures are configured to accommodate a vessel configured as a flexible tube.
11-13. (canceled)
The optical detection assembly of claim 22, configured such that relative movement of said at least a portion of said at least one of the first and second fluid-adjustment structures toward said at least a portion of the other one of the first and second fluid-adjustment structures increases the thickness of the biological fluid.
15-17. (canceled)
The optical detection assembly of claim 22, wherein the light source is associated to the first fluid-adjustment structure and the light detector is associated to the second fluid-adjustment structure such that movement of said at least a portion of said at least one of the first and second fluid-adjustment structures with respect to said at least a portion of the other one of the first and second fluid-adjustment structures changes a distance between the light source and the light detector.
The optical detection assembly of claim 22, wherein a distance between the light source and the light detector is configured to remain unchanged upon movement of said at least a portion of said at least one of the first and second fluid-adjustment structures with respect to said at least a portion of the other one of the first and second fluid-adjustment structures.
20-21. (canceled)
