Abstract:
1. A blood pressure sleeve comprising: a first sheet having a top surface and a bottom surface; a second sheet having a top surface and a bottom surface; said second sheet being attached to said first sheet and defining an inflatable interior portion between the bottom surface of said first sheet and the top surface of said second sheet, said inflatable interior portion including an opening that receives a port fluidly interconnecting the interior of said inflatable portion with the exterior of said sleeve, said first sheet including an axial extension having a slotted portion aligned with said port such that said port can be fitted within said slotted portion when said sleeve is circumferentially wrapped about the limb of a patient wherein the top surface of said first sheet is defined by a non-woven surface and the bottom surface is defined by a fluid impermeable surface, and in which at least one of said non-woven and fluid impermeable surfaces of at least a portion of said first sheet is treated to reduce frictional effects between contacting top and bottom surfaces of said first sheet in a wrapped configuration wherein at least a portion of one of the contacting top and bottom surfaces of the first sheet is treated such that at least one of the coefficient of static friction and the coefficient of dynamic friction between the top and bottom surfaces is increased from an untreated level.
