Abstract
Abstract A head restraint system for use with a backboard includes a stretchable base pad which defines a rectangular envelope for fitting tightly over one end of the backboard and a pair of head blocks which are adapted to engage a patient's head. The base pad is positioned on the backboard and under a patient's head and the pair of head blocks positioned thereon with one on each side of the patient's head. A base portion of each of the blocks includes hook material for attachment to a top surface of the base pad. The base pad also includes at least one ring-like element on one edge thereof and straps are provided for passing through the ring-like element to press and hold the head blocks downwardly against the upper surface of the base pad and inwardly against the patient's head.

Claim 1
Independent Claim
225 words
A head restraint system for use in transporting an injured patient on a longitudinally extending spine/backboard comprising a stretchable base pad defining a rectangular envelope having superposed top and bottom layers which are closed along at least a portion of each of three sides thereof and open on a fourth side and constructed and arranged so that the envelope can be stretched in a lateral direction parallel to its open side and slipped over one end of the spine/backboard and pulled downwardly along the spine/backboard's longitudinal axis until one of the closed sides opposite from said open side and between said lateral sides engage the end of the spine/backboard and upon release of the lateral stretched sides tightly engages the sides of the spine/backboard, a pair of longitudinally extending head blocks having base portions adapted to engage said top layer and upwardly extending portions adapted to engage the side of a patient's head means for holding said blocks on said top layer on each side of the patient's head, fastening means fixed to said closed portion of one of said lateral sides of said envelope and strap means for engaging said fastening means and for pressing said blocks downwardly against said top layer and inwardly against the side of the patient's head to thereby prevent movement of the patient's head during movement of the patient.
