Abstract
Abstract A splint to be applied by a policeman, paramedic, or fireman during rescue operation to a suspected cervical spine injury victim. The splint is designed for quick on-site installation to immobilize the head and cervical area before any attempt is made to move the victim. The splint is composed of two half sections. Each section is mounted on a shoulder harness and is designed to be fitted independently on either side of the head. The two sections are then connected to form a cage surrounding the victim's head. The head is secured within the cage by means of inflatable neck pillows. The splint may be fitted with an accessory designed to apply traction to the cervical vertebrae during emergency room treatment.

Claim 1
Independent Claim
287 words
A device for immobilizing the head and cervical spine of an injury victim which comprises: a body harness having first and second half sections, means for releasibly connecting said half sections together, said body harness being adopted to embrace the thoracic region, the shoulders, the sides and the back of a victim, a head cage comprising a first and second pair of elongated rigid members and first and second U shaped members, said first pair being mounted on said first half section in spaced relationship such that said first pair of rigid members projects substantially upward around the head of a victim when said harness is worn by a victim, said second pair being mounted on said second half section in spaced relation such that said second pair of rigid members project substantially upward around the head of a victim when said harness is worn by a victim, said first U shaped member being mounted horizontally on said first pair of rigid members, said second U shaped member being mounted horizontally on said second pair of rigid members, said U shaped members being sized and positioned such that they extend completely around the head of a victim when said harness is worn by a victim, means for releasibly connecting the ends of the U shaped members together, said head cage further comprising an inflatable air pillow shaped like an open toroid insertable within said first and second pair of rigid members such that when said harness is worn said pillow is positioned between said rigid members and the neck of a victim and when inflated said pillow immobilizes the head of a victim within the confines of said rigid members by encircling the neck of a victim.
