Abstract
Abstract A splint device for the spinal immobilization of a patient. The splint includes a central support portion (11) and two pairs of laterally extending flexible wings adapted to extend, respectively, about the head and about the body of a patient. The central support portion (11) is formed in two parts (61,65) joined together by a lockable hinge (60) such that the angle of inclination of a head part of the splint to the body part thereof may be selectively adjusted between 0<sup>o</sup> and 30<sup>o</sup>.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
186 words
A splint device for the spinal immobilization of a patient, comprising a generally rigid central support portion adapted to extend from the lumbar region to the head region adjacent the spine of a patient, two pairs of laterally exending flexible wings attached to the side edges of the support portion, a first pair of the wings being adapted to extend about the head of a patient, and a second pair of the wings being adapted to extend about at least one of the thoracic and lumbar regions of the patient, first engagement means adapted to retain the first pair of wings about the head of a patient and second engagement means adapted to retain the said second pair of wings about at least one of the thoracic and lumbar regions of a patient, the splint device being characterized in that the central support portion is formed integrally with the wings from a synthetic plastic material and has a longitudinal cavity and includes within the cavity a plurality of longitudinal and diagonal stiffening ribs adapted to render the central support portion substantially inflexible laterally along its length.
Claim 2
Dependent Claim
186 words
A splint device for the spinal immobilization of a patient, comprising a generally rigid central support portion adapted to extend from the lumbar region to the head region adjacent the spine of a patient, two pairs of laterally exending flexible wings attached to the side edges of the support portion, a first pair of the wings being adapted to extend about the head of a patient, and a second pair of the wings being adapted to extend about at least one of the thoracic and lumbar regions of the patient, first engagement means adapted to retain the first pair of wings about the head of a patient and second engagement means adapted to retain the said second pair of wings about at least one of the thoracic and lumbar regions of a patient, the splint device being characterized in that the central support portion is formed integrally with the wings from a synthetic plastic material and has a longitudinal cavity and includes within the cavity a plurality of longitudinal and diagonal stiffening ribs adapted to render the central support portion substantially inflexible laterally along its length.
Claim 3
Dependent Claim
22 words
A splint device as claimed in claim 1, in which the said cavity is concave on its side proximal to the patient.
Claim 4
Dependent Claim
27 words
A splint device as claimed in claim 1, in which the stiffening ribs include two sets of substantially parallel diagonal ribs, ribs of the respective sets intersecting.
Claim 5
Dependent Claim
32 words
A splint device as claimed in claim 1, in which a closure panel is provided on the central support portion to cover the cavity and the integrally formed stiffening ribs contained therein.
Claim 6
Dependent Claim
40 words
A splint device as claimed in claim 4, in which the closure panel is so connected with the central support portion that its outer surface is flush with the outer surface of the central support portion of the splint device.
Claim 7
Dependent Claim
42 words
A splint device as claimed in claim 1, in which the wings of at least one pair each reduce in thickness in tapering fashion from a position adjacent the central support portion to a position adjacent the free end of that wing.
Claim 8
Dependent Claim
45 words
A splint device as claimed in claim 6, in which each wing tapers in thickness from a thickness of from 3 to 5 mm adjacent the central support portion to a thickness of from 0.5 to 2.5 mm adjacent the free end of that wing.
Claim 9
Dependent Claim
29 words
A splint device as claimed in claim 1, in which the wings of at least one pair thereof are formed with an array of longitudinally extending, substantially parallel corrugations.
Claim 10
Dependent Claim
21 words
A splint device as claimed in claim 1, in which the central support portion and the wings are made from polypropylene.
Claim 11
Dependent Claim
47 words
A splint device as claimed in claim 1, in which the first engagement means comprise a pair of straps adapted to be passed around the forehead and chin respectively of a patient and connected at each end to a respective one of the first pair of wings.
Claim 12
Dependent Claim
45 words
A splint device as claimed in claim 1, in which the second engagement means comprise straps adapted to pass respectively around the legs and abdomen of a patient, the straps being connected at each end to a respective one of the second pair of wings.
