Abstract
Abstract A surgical wicking device utilizing a hollow conduit having a first end portion and a second portion terminating in an open end. The first end portion is connected to a suction source. A porous element having an outer surface and a matrix within the same is capable of transporting fluids, including blood, from the outer surface to a inner or central reservoir or zone of the matrix by only capillary flow. The open end of the second end portion of the hollow flexible conduit is held to the interior of porous element adjacent the matrix inner zone, to permit aspiration of fluids from the matrix central zone to the conduit.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
170 words
A surgical fluid aspiration device, comprising: a. means for providing a suction force; b. a conduit having a first end portion and a second end portion, terminating in open end, said first end portion being connected to the means for providing a suction force; c. a porous element possessing an outer surface and a matrix within, said matrix having an inner zone spaced from said outer surface, said porous element being capable of transporting fluids from said outer surface to said matrix inner zone by capillary flow only; d. fastening means for holding said open end of said second end portion of said conduit to the interior of said porous element adjacent said matrix inner zone to permit flow of fluids from said matrix inner zone to said conduit only by the influence of the suction force; and e. means for determining the magnitude of the suction force of the means for providing a suction force, to provide the suction force only to said inner zone of said porous element.
Claim 2
Dependent Claim
170 words
A surgical fluid aspiration device, comprising: a. means for providing a suction force; b. a conduit having a first end portion and a second end portion, terminating in open end, said first end portion being connected to the means for providing a suction force; c. a porous element possessing an outer surface and a matrix within, said matrix having an inner zone spaced from said outer surface, said porous element being capable of transporting fluids from said outer surface to said matrix inner zone by capillary flow only; d. fastening means for holding said open end of said second end portion of said conduit to the interior of said porous element adjacent said matrix inner zone to permit flow of fluids from said matrix inner zone to said conduit only by the influence of the suction force; and e. means for determining the magnitude of the suction force of the means for providing a suction force, to provide the suction force only to said inner zone of said porous element.
Claim 3
Dependent Claim
16 words
