An improved extraction splint capable of immobilizing the head, shoulders and vertebral column of an injured person, which splint comprises (a) a frame formed from pliable material, said frame comprising 1. a central portion having a length which approximates the length of a human torso; 2. a neck and head brace portion which extends longitudinally from one end of said central portion; 3. and at least one over-the-shoulder brace portion which is an elongated strip disposed lengthwise of said central portion and which is attached at one end to the central portion adjacent that end of the central portion from which the neck and head brace portion extends; 4. wherein the several portions of said frame may be manually deformed to accommodate the splint to the contortions in which an injured person may be found; (b) and a plurality of straps, individual ones of said straps being engaged respectively with said central, neck and head brace portion and said shoulder brace portions, each of said straps having a reach sufficient to clasp the engaged portion of the frame to a part of the body of an injured person.
Claim 2
Dependent Claim 188 words
An improved extraction splint capable of immobilizing the head, shoulders and vertebral column of an injured person, which splint comprises (a) a frame formed from pliable material, said frame comprising 1. a central portion having a length which approximates the length of a human torso; 2. a neck and head brace portion which extends longitudinally from one end of said central portion; 3. and at least one over-the-shoulder brace portion which is an elongated strip disposed lengthwise of said central portion and which is attached at one end to the central portion adjacent that end of the central portion from which the neck and head brace portion extends; 4. wherein the several portions of said frame may be manually deformed to accommodate the splint to the contortions in which an injured person may be found; (b) and a plurality of straps, individual ones of said straps being engaged respectively with said central, neck and head brace portion and said shoulder brace portions, each of said straps having a reach sufficient to clasp the engaged portion of the frame to a part of the body of an injured person.
Claim 3
Dependent Claim 75 words
An improved extraction splint according to claim 1 in which said central portion has a width which is less than the width of a human torso but greater than the width of the human neck, and is provided with right and left shoulder brace portions disposed lengthwise adjacent the respective longitudinal edge of said central portion and attached thereto adjacent that end of the central portion from which the neck and head brace portion extends.
Claim 4
Dependent Claim 37 words
An improved extraction splint according to either of claims 1 or 2 and in which the several portions of said frame are formed unitarily from a sheet of metallurgically soft metal which is substantially transparent to X-rays.
Claim 5
Dependent Claim 308 words
An improved extraction splint capable of immobilizing the head, shoulders and vertebral column relative to the torso of an injured person, which splint comprises (a) a unitary frame formed from a sheet of metallurgically soft, pliable metal which is substantially transparent to X-rays, said frame comprising; (1) a substantially rectangular central portion having a length which approximates the length of the torso of a human and having a width which is less than the width of the torso but greater than the width of the neck of a human; (2) a T-shaped neck and head brace portion with the stem of the T extending longitudinally from one end of said central portion for a distance which approximates the length of a human neck and head and the cross of the T extending substantially parallel to the end of said central portion; (3) right and left shoulder brace portions, each of which is substantially L-shaped with the stem of the L disposed lengthwise adjacent the respective longitudinal edge of said central portion and the distal end of the foot of the L joined to said central portion adjacent that end of the central portion from which said neck and head brace extends, wherein the several portions of said frame may be manually deformed from the initial flat form to accommodate the splint to the contortions in which an injured person may be found; and (b) at least one pair of straps for each of said central, neck and head and shoulder brace portions, respectively, one end of each such straps being fixed to the respective portion, and fastening means for each pair of straps for securing the distal ends of the straps together, the reach of each pair of straps being sufficient to clasp that portion of the frame to a part of the body of an injured person.
Claim 6
Dependent Claim 308 words
An improved extraction splint capable of immobilizing the head, shoulders and vertebral column relative to the torso of an injured person, which splint comprises (a) a unitary frame formed from a sheet of metallurgically soft, pliable metal which is substantially transparent to X-rays, said frame comprising; (1) a substantially rectangular central portion having a length which approximates the length of the torso of a human and having a width which is less than the width of the torso but greater than the width of the neck of a human; (2) a T-shaped neck and head brace portion with the stem of the T extending longitudinally from one end of said central portion for a distance which approximates the length of a human neck and head and the cross of the T extending substantially parallel to the end of said central portion; (3) right and left shoulder brace portions, each of which is substantially L-shaped with the stem of the L disposed lengthwise adjacent the respective longitudinal edge of said central portion and the distal end of the foot of the L joined to said central portion adjacent that end of the central portion from which said neck and head brace extends, wherein the several portions of said frame may be manually deformed from the initial flat form to accommodate the splint to the contortions in which an injured person may be found; and (b) at least one pair of straps for each of said central, neck and head and shoulder brace portions, respectively, one end of each such straps being fixed to the respective portion, and fastening means for each pair of straps for securing the distal ends of the straps together, the reach of each pair of straps being sufficient to clasp that portion of the frame to a part of the body of an injured person.
