Abstract
Abstract A medical arm support that substantially immobilizes the arm to facilitate intravenous injection of fluid into the arm adjacent the elbow, but which allows a limited amount of natural flexure of the arm at the elbow for patient comfort. A spiral, slightly flexible section joins a panel overlying the forearm with a support panel underlying the upper arm to produce the desired immobility while allowing limited flexure. Upstanding posts secure and hold flexible tubing that supplies the fluid being injected to the forearm panel to prevent relative needle movement during flexing of the arm.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
236 words
A surgical arm support for substantially immobilizing the arm of a patient during intravenous injection into the forearm adjacent the elbow of fluid supplied through flexible tubing, comprising: an upper arm panel comprising a first generally flat elongate member having terminal ends and adapted to be disposed above the elbow, said member conforming to the arm and configured to underly and support the upper arm and adapted to be secured thereto; a forearm panel comprising a second, generally flat elongate member having terminal ends adapted to be disposed below the elbow, said member conforming to the arm and configured to overly and constrain the forearm and adapted to be secured thereto; and a spiral connecting section configured to extend at least partially around the arm, said spiral section being generally flat and connected to the upper arm member between said ends and extending longitudinally and helically away from said upper arm member to said forearm member wherein said panels are both spaced apart longitudinally as well as in opposed relationship to one another so as to be attached to the arm, said spiral connecting section rigidly joining said upper arm panel to said forearm panel whereby said arm support suBstantially immobilizes the elbow joint of the arm in a supine position thereof, said spiral section being capable of limited flexure to allow limited, natural bending of the arm at the elbow away from the supine position.
Claim 2
Dependent Claim
236 words
A surgical arm support for substantially immobilizing the arm of a patient during intravenous injection into the forearm adjacent the elbow of fluid supplied through flexible tubing, comprising: an upper arm panel comprising a first generally flat elongate member having terminal ends and adapted to be disposed above the elbow, said member conforming to the arm and configured to underly and support the upper arm and adapted to be secured thereto; a forearm panel comprising a second, generally flat elongate member having terminal ends adapted to be disposed below the elbow, said member conforming to the arm and configured to overly and constrain the forearm and adapted to be secured thereto; and a spiral connecting section configured to extend at least partially around the arm, said spiral section being generally flat and connected to the upper arm member between said ends and extending longitudinally and helically away from said upper arm member to said forearm member wherein said panels are both spaced apart longitudinally as well as in opposed relationship to one another so as to be attached to the arm, said spiral connecting section rigidly joining said upper arm panel to said forearm panel whereby said arm support suBstantially immobilizes the elbow joint of the arm in a supine position thereof, said spiral section being capable of limited flexure to allow limited, natural bending of the arm at the elbow away from the supine position.
Claim 3
Dependent Claim
59 words
An arm support as set forth in claim 1, wherein there is provided upstanding support means on said forearm panel adapted to engage the tubing supplying the fluid being injected and securely fasten the tubing to said forearm panel whereby said limited bending of the arm does not interfere with the intravenous injection of the fluid into the forearm.
Claim 4
Dependent Claim
41 words
An arm support as set forth in claim 2, wherein said support means comprises a plurality of upstanding posts integrally formed upon said forearm panel and having apertures therein for receiving and securely engaging the tubing supplying the fluid being injected.
Claim 5
Dependent Claim
44 words
An arm support as set forth in claim 1, wherein said upper arm panel and forearm panel extend longitudinally along the arm and are transversely curved in configurations generally complementary to the transverse curvature of the arm to comfortably and snugly receive the arm.
Claim 6
Dependent Claim
48 words
An arm support as set forth in claim 4, wherein said upper arm panel is disposed to extend longitudinally at an angle relative to said forearm panel generally complementary to the angle formed between the upper arm and the forearm when the arm is in a supine position.
Claim 7
Dependent Claim
25 words
An arm support as set forth in claim 5, wherein said angle between said upper arm panel and said forearm panel is approximately ten degrees.
Claim 8
Dependent Claim
32 words
An arm support as set forth in claim 4, wherein said upper arm panel and said forearm panel are longitudinally curved in configurations generally complementary to the longitudinally curvature of the arm.
Claim 9
Dependent Claim
39 words
An arm support as set forth in claim 1, wherein there is provided an elbow rest panel joined to one end of said upper arm panel and extending forwardly therefrom to underly and support the elbow of the arm.
Claim 10
Dependent Claim
28 words
An arm support as set forth in claim 8, said elbow panel being transversely and longitudinally curved to snugly and comfortably receive the elbow joint of the arm.
Claim 11
Dependent Claim
32 words
An arm support as set forth in claim 8, said spiral section being integrally joined to said upper arm panel adjacent said one end thereof and integrally joined to said forearm panel.
