Abstract
Abstract A pressure cuff for medical therapeutic purposes is formed from a single walled, fluid impervious casing which is sealed to the body of a patient by one or more flexible, body-conforming, adherent flaps of thin film sheet material. Valves in the casing provide direct access to the body portion to be treated and allow maintenance of a controlled atmosphere around the body portion. A modification allows the use of both positive and negative pressures.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
235 words
A therapeutic cuff for an animal body comprising A. a relatively inflexible casing for positioning over a body portion and forming a chamber therewith, B. at least one thin, flexible, body conforming, adherent, elongated sheet having a first end thereof circumferentially attached to said casing and having a second end thereof extending radially inwardly from said casing for engagement along a substantial area, intermediate said ends, with a body positioned within said casing to thereby form a circumferentially extending fluid tight sealing flap surrounding said body portion and isolating the interior of said chamber from the exterior thereof, the diameter of said flap at its ends and all portions therebetween being greater than that of the body portion it contacts whereby said flap exerts substantially no force of its own against said body portion, C. means forming a circumferentially extending closed auxiliary chamber on an interior wall of said casing and having a deformable wall in contact with a surface of said flap opposite the surface in contact with said body portion, said chamber being pressurized to substantially atmospheric pressure to thereby exert minimal force against said flap and said body portion when the pressure within said casing is greater than atmospheric pressure and to exert a sealing force against said flap and body portion when the pressure in said chamber is less than atmospheric, and D. means on said cuff for pressurizing said chamber.
Claim 2
Dependent Claim
235 words
A therapeutic cuff for an animal body comprising A. a relatively inflexible casing for positioning over a body portion and forming a chamber therewith, B. at least one thin, flexible, body conforming, adherent, elongated sheet having a first end thereof circumferentially attached to said casing and having a second end thereof extending radially inwardly from said casing for engagement along a substantial area, intermediate said ends, with a body positioned within said casing to thereby form a circumferentially extending fluid tight sealing flap surrounding said body portion and isolating the interior of said chamber from the exterior thereof, the diameter of said flap at its ends and all portions therebetween being greater than that of the body portion it contacts whereby said flap exerts substantially no force of its own against said body portion, C. means forming a circumferentially extending closed auxiliary chamber on an interior wall of said casing and having a deformable wall in contact with a surface of said flap opposite the surface in contact with said body portion, said chamber being pressurized to substantially atmospheric pressure to thereby exert minimal force against said flap and said body portion when the pressure within said casing is greater than atmospheric pressure and to exert a sealing force against said flap and body portion when the pressure in said chamber is less than atmospheric, and D. means on said cuff for pressurizing said chamber.
Claim 3
Dependent Claim
24 words
A therapeutic cuff in accordance with claim 1 in which said sheet increasingly frictionally adheres to said body portion when said chamber is pressurized.
Claim 4
Dependent Claim
34 words
A therapeutic cuff in accordance with claim 1 in which said sheet is sufficiently thin to snugly conform to a body contour it engages and sufficiently thick to withstand rupture by the chamber pressure.
Claim 5
Dependent Claim
16 words
A therapeutic cuff in accordance with claim 3 in which said sheet is formed of rubber.
Claim 6
Dependent Claim
16 words
A therapeutic cuff in accordance with claim 3 in which said sheet is formed of plastic.
Claim 7
Dependent Claim
31 words
A therapeutic cuff in accordance with claim 3 in which said sheet is formed of a plastic that is treated to increase its frictional engagement with a body surface it contacts.
Claim 8
Dependent Claim
49 words
A therapeutic cuff in accordance with claim 3 in which a viscous paste is applied between the body-conforming sheet and the body portion to which it is to be sealed to thereby increase adherence between said body portion and said sheet and further increase the security of the seal.
Claim 9
Dependent Claim
25 words
A therapeutic cuff in accordance with claim 1 in which said casing is cylindrical in shape and is adapted to completely encompass said body portion.
Claim 10
Dependent Claim
108 words
A therapeutic cuff for an animal body, said cuff comprising A. a casing for forming a hollow air chamber surrounding a body portion to be treated, B. means for extending between said casing and said body portion for sealing said chamber fluid-tight; and C. means forming a flexible wall in said casing and of substantially larger cross section than the chamber containing the body portion to be treated and movable inwardly and outwardly of said chamber to thereby change the pressure therein at a rate greater than that achievable by flexible walls of cross sectioN comparable to that of the chamber containing the body portion to be treated.
Claim 11
Dependent Claim
108 words
A therapeutic cuff for an animal body, said cuff comprising A. a casing for forming a hollow air chamber surrounding a body portion to be treated, B. means for extending between said casing and said body portion for sealing said chamber fluid-tight; and C. means forming a flexible wall in said casing and of substantially larger cross section than the chamber containing the body portion to be treated and movable inwardly and outwardly of said chamber to thereby change the pressure therein at a rate greater than that achievable by flexible walls of cross sectioN comparable to that of the chamber containing the body portion to be treated.
Claim 12
Dependent Claim
17 words
A therapeutic cuff according to claim 9 in which said flexible wall comprises a resilient membrane diaphragm.
Claim 13
Dependent Claim
19 words
A therapeutic cuff according to claim 9 in which said flexible wall is in the form of a bellows.
Claim 14
Dependent Claim
21 words
A therapeutic cuff according to claim 9 which includes reciprocating means for moving said wall inwardly and outwardly of said chamber.
