Abstract

Abstract An elongated, waterproof, flexible bag having an opening at one end through which a cast-bound limb is inserted and sealing means around the opening including an inflatable cuff of substantially toroidal configuration and sufficiently wide to distribute the sealing pressure over a large enough area to prevent interference with the blood supply to the injured limb when the cuff is inflated. Longitudinally oriented flotation sections may be disposed in the wall of the bag to further aid in buoying up the cast-bound limb while swimming and/or for therapeutic water treatments.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 124 words
A cast cover for protecting and buoying up the cast-bound limb of a wearer comprising, an elongated, waterproof, flexible bag having an opening at one end thereof, sealing means at said opening comprising an inflatable cuff of toroidal configuration having sufficient width to distribute the sealing pressure over a relatively wide area and adapted to fit closely around the limb of the wearer above the top of the cast, longitudinally disposed flotation sections secured to and made part of said cast cover for providing additional buoyancy to the cast-bound limb, and means for inflating said cuff to produce a seal for preventing water from entering the elongated bag through the opening without causing interference with the normal flow of blood to the cast-bound limb.
Claim 2
Dependent Claim 124 words
A cast cover for protecting and buoying up the cast-bound limb of a wearer comprising, an elongated, waterproof, flexible bag having an opening at one end thereof, sealing means at said opening comprising an inflatable cuff of toroidal configuration having sufficient width to distribute the sealing pressure over a relatively wide area and adapted to fit closely around the limb of the wearer above the top of the cast, longitudinally disposed flotation sections secured to and made part of said cast cover for providing additional buoyancy to the cast-bound limb, and means for inflating said cuff to produce a seal for preventing water from entering the elongated bag through the opening without causing interference with the normal flow of blood to the cast-bound limb.
Claim 3
Dependent Claim 19 words
The cast cover defined in claim 1 including a non-porous foam lining on the inner portion of said cuff.
Claim 4
Dependent Claim 20 words
The cast cover defined in claim 1 including a soft latex rubber surface on the inner portion of said cuff.
Claim 5
Dependent Claim 33 words
The cast cover defined in claim 1 including a suitable protective material at the end of said bag opposite said opening to protect said cover from puncture by rough edges of the cast.
Claim 6
Dependent Claim 21 words
The cast cover defined in claim 1 wherein the longitudinally disposed flotation sections include separate means for inflating said flotation sections.
