Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
153 words
A protective drape for separating solid specimens from liquids collected during urinary procedures, consisting of a rectangular impermeable sheet of flexible material having a fenestration centered approximately on the longitudinal axis of the sheet and spaced adajcent one end thereof, said fenestration being sufficiently large to enable said liquid and solid specimens to flow from a patient on one side of the sheet through said fenestration and onto the other side of the sheet, said sheet having a drainage and collection area centered approximately on the longitudinal axis of the sheet and spaced adajcent the opposite end thereof, the drainage and collection area being constituted by a plurality of spaced slits, each of said slits being formed by cutting without removal of material and lying transversely of the length of the sheet for permitting said liquid to flow therethrough, the space between pairs of said slits being effective to collect said solid specimens.
Claim 2
Dependent Claim
153 words
A protective drape for separating solid specimens from liquids collected during urinary procedures, consisting of a rectangular impermeable sheet of flexible material having a fenestration centered approximately on the longitudinal axis of the sheet and spaced adajcent one end thereof, said fenestration being sufficiently large to enable said liquid and solid specimens to flow from a patient on one side of the sheet through said fenestration and onto the other side of the sheet, said sheet having a drainage and collection area centered approximately on the longitudinal axis of the sheet and spaced adajcent the opposite end thereof, the drainage and collection area being constituted by a plurality of spaced slits, each of said slits being formed by cutting without removal of material and lying transversely of the length of the sheet for permitting said liquid to flow therethrough, the space between pairs of said slits being effective to collect said solid specimens.
Claim 3
Dependent Claim
45 words
A protective drape according to claim 1 wherein the sheet includes a lower liquid impermeable layer and an upper somewhat absorbent layer, said upper layer being effective to decrease the flow of liquid adjacent the slits to assist in said collection of said solid specimens.
Claim 4
Dependent Claim
46 words
A protective drape according to claim 1 wherein the distance between the fenestration and the drainage and collection area is sufficient to permit a bight of the material to be inserted under the patient when the drainage and collection area is located over a waste receptacle.
Claim 5
Dependent Claim
16 words
A protective drape according to claim 1 wherein at least some of the slits are curved.
Claim 6
Dependent Claim
29 words
A protective drape according to claim 4 wherein said slits are in rows extending transversely of the length of said sheet and alternate slits in each row face oppositely.
