CELL COLLECTING DEVICE
A cell collecting device is configured to collect target cells from a fluid sample such as blood or physiological fluid. The cell collecting device includes a conduit through which a fluid sample containing target cells passes. The cell collecting device further includes a screen filter installed inside the conduit and configured to guide the target cells toward a specified region. The screen filter includes a plurality of filtering holes for filtering the target cells.
1 . A cell collecting device, comprising:
a conduit through which a fluid sample containing target cells passes; and
a screen filter installed inside the conduit and configured to guide the target cells toward a specified region, the screen filter including a plurality of filtering holes for filtering the target cells.
2 . The cell collecting device of claim 1 , wherein the conduit includes a tubular wall defining a passage for passing the fluid sample therethrough, the screen filter configured to guide the target cells toward a boundary region where the screen filter meets with the tubular wall.
3 . The cell collecting device of claim 2 , wherein the screen filter is obliquely installed in the passage along a flow direction of the fluid sample.
4 . The cell collecting device of claim 3 , wherein the screen filter includes a trap formed at a downstream end of the screen filter so as to gather the target cells.
5 . The cell collecting device of claim 2 , wherein the screen filter is formed into a curvilinear shape.
6 . The cell collecting device of claim 2 , wherein the conduit includes an outlet formed near the boundary region and kept in communication with the boundary region so that the target cells can be discharged through the outlet.
7 . The cell collecting device of claim 2 , wherein the screen filter includes a convex portion formed to guide the target cells toward the boundary region.
8 . The cell collecting device of claim 1 , wherein the screen filter includes a concave portion formed to guide and gather the target cells.
9 . The cell collecting device of claim 8 , wherein the concave portion is formed at a center of the screen filter so as to gather the target cells.
10 . The cell collecting device of claim 9 , wherein the screen filter further includes a trap formed at a center of the concave portion so as to receive the target cells.
