Abstract
Abstract The invention comprises a limb support having upper, middle and lower sections. The upper section includes two compartments for receiving a fluid or ice and forming a trough to receive a limb of the patient. The middle section is in the form of an inflatable compartment for adjusting the height of the unit. The lower section includes three triangular-shaped compartments for adjusting the angle at which the unit is to be rested.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
166 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including an upper section and a lower section; c. said upper section having a trough formed therein; d. said lower section having upper and lower substantially parallel walls and being divided into at least two separate compartments; e. means for inserting fluid into said at least two separate compartments; f. said at least two separate compartments being formed substantially triangular in cross-section, a wall between two of said at least two separate compartments being inclined upwardly from said lower wall of the support and contacting a compartment thereabove; whereby when one of said separate compartments has fluid therein and another of said separate compartments is substantially free of fluid, the support and trough will tilt; and when all of said separate compartments are substantially full of fluid the support will be substantially horizontal.
Claim 2
Dependent Claim
166 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including an upper section and a lower section; c. said upper section having a trough formed therein; d. said lower section having upper and lower substantially parallel walls and being divided into at least two separate compartments; e. means for inserting fluid into said at least two separate compartments; f. said at least two separate compartments being formed substantially triangular in cross-section, a wall between two of said at least two separate compartments being inclined upwardly from said lower wall of the support and contacting a compartment thereabove; whereby when one of said separate compartments has fluid therein and another of said separate compartments is substantially free of fluid, the support and trough will tilt; and when all of said separate compartments are substantially full of fluid the support will be substantially horizontal.
Claim 3
Dependent Claim
19 words
A body limb elevator as defined in claim 1 wherein said fluid is air, whereby said compartments are inflated.
Claim 4
Dependent Claim
32 words
A body limb elevator as defined in claim 1 wherein said at least one upper section includes at least one relatively large opening therein for the insertion of ice or the like.
Claim 5
Dependent Claim
139 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including at least an upper section and a lower section; c. said upper section having a trough formed therein; d. said lower section being divided into three separate compartments; e. said three separate compartments being formed with triangular cross-sections; f. wherein one of said three compartments has a bottom extending substantially the length and width of the support and having a pair of inclined walls having an apex substantially in the center of the length of the support, said inclined walls forming a wall of the other two of said three compartments; and g. means for inserting a fluid in at least some of said compartments.
Claim 6
Dependent Claim
139 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including at least an upper section and a lower section; c. said upper section having a trough formed therein; d. said lower section being divided into three separate compartments; e. said three separate compartments being formed with triangular cross-sections; f. wherein one of said three compartments has a bottom extending substantially the length and width of the support and having a pair of inclined walls having an apex substantially in the center of the length of the support, said inclined walls forming a wall of the other two of said three compartments; and g. means for inserting a fluid in at least some of said compartments.
Claim 7
Dependent Claim
103 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including at least an upper section and a lower section; c. said upper section including a pair of compartments forming a trough therein; d. said lower section including three compartments having triangular cross-sections; e. a third section being a middle section between said upper and lower sections and being in the form of a single compartment; and f. means for inserting a fluid in at least some of said compartments.
Claim 8
Dependent Claim
103 words
A body limb elevator and support comprising: a. a plurality of air and water-tight sections in the form of compartments made of flexible material and being sealed from each other; b. the support including at least an upper section and a lower section; c. said upper section including a pair of compartments forming a trough therein; d. said lower section including three compartments having triangular cross-sections; e. a third section being a middle section between said upper and lower sections and being in the form of a single compartment; and f. means for inserting a fluid in at least some of said compartments.
Claim 9
Dependent Claim
90 words
A body limb elevator as defined in claim 5 wherein the bottom of said trough abutes against the top of said middle section, and one of said three compartments having a bottom extending substantially the length and width of the support and including a pair of inclined walls having an apex substantially in the center of the length of the support, said inclined walls forming a wall of the other two of said three compartments, and the bottom of said middle section forming another wall of said other two compartments.
