Abstract
Abstract A device is provided which is adapted for use in manually cleaning a soiled segment of a surgical blade. The device includes a hollow casing having a base portion and upwardly extending wall portions that form an elongated slot in an exterior surface of the casing. The slot is arranged so that the soiled segment of a surgical blade may be inserted through the slot into the casing and may be moved longitudinally of the slot. A compressible frictional media is disposed within the hollow casing and is adapted to exert compressive frictional force on the inserted surgical blade segment to effect cleaning thereof when the blade is moved longitudinally of the slot.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
135 words
A device for use in cleaning a surgical blade soiled with adherent liquid an non-liquid matter comprising a hollow casing having an exposed surface provided with an elongated narrow slot sized to accommodate and guide the soiled blade portion when the latter is inserted at an acute angle through the slot and moved longitudinally thereof, and a frictional medium disposed within said casing having only a portion thereof aligned with said slot, being only accessible to the blade portion through said slot, and extending the full length of said slot; said medium resiliently engaging a concealed surface of the casing circumjacent the slot and being adapted to exert a compressive frictional force on the inserted soiled blade portion to effect cleaning thereof when the angularly disposed, soiled blade portion is moved longitudinally of said slot.
Claim 2
Independent Claim
135 words
A device for use in cleaning a surgical blade soiled with adherent liquid an non-liquid matter comprising a hollow casing having an exposed surface provided with an elongated narrow slot sized to accommodate and guide the soiled blade portion when the latter is inserted at an acute angle through the slot and moved longitudinally thereof, and a frictional medium disposed within said casing having only a portion thereof aligned with said slot, being only accessible to the blade portion through said slot, and extending the full length of said slot; said medium resiliently engaging a concealed surface of the casing circumjacent the slot and being adapted to exert a compressive frictional force on the inserted soiled blade portion to effect cleaning thereof when the angularly disposed, soiled blade portion is moved longitudinally of said slot.
Claim 3
Dependent Claim
35 words
The device of claim 1 wherein the hollow casing has a generally cylindrical cross sectional configuration, and the exposed surface of said casing is provided with upwardly extending guide flanges defining the elongated narrow slot.
Claim 4
Dependent Claim
72 words
The device of claim 1 wherein the hollow casing is comprised of a base portion and wall portions having upper and lower segments; said lower wall segments extending upwardly and at a like acute angle from the base portion and said upper wall segments extending inwardly from the upper edge portions of said lower wall segments; said upper wall segments being in substantially coplanar relation forming the exposed surface of said casing.
Claim 5
Dependent Claim
22 words
The device of claim 3 wherein the lower wall segments extend upwardly and at a like obtuse angle from the base portion.
Claim 6
Dependent Claim
29 words
The device of claim 1 wherein the hollow casing is comprised of a resilient synthetic material formed so that said hollow casing exerts compressive force on the frictional medium.
