Abstract

Abstract The invention provides an immobilizer for use in X-ray, and surgical procedures. The immobilizer has a back which is adapted to be rigid or bent at various positions. It also has flexible straps for securing different sections of a patient's body against movement in the immobilizer. The immobilizer comprises two parts, a radiotransparent backing member and a radiotransparent flexible part. The backing member is removably inserted under the flexible member with the backing member held firmly by loops and slots on the back of the flexible member. The knee and elbow sections can be produced so as to be used individually and have a unique method of restraining these appendages. The elbow and head restraints are adjustable for patients of different heights.

Claim 11
Dependent Claim 184 words
The immobilizer of claim 1 wherein said restraining means comprises pairs of straps attached to said flexible member with mating means on at least one surface of each strap to secure the ends of said straps together when disposed around a portion of said patient; said straps disposed to correspond to the knee and elbow locations of said patient, said straps having slots spaced from the point of attachment to said flexible member; said ends of said straps adapted to be looped through said slots to provide adjustable restraining means for the limbs of said patient; said ends of each said strap extending around the region of a portion of the limb to be immobilized, passing through its respective slot, drawn tightly around said region of said limb portion, and passing again around and over said limb region to attach to said other of said pair of straps; said elbow restraining means including a loop on the posterior surface of said flexible member and extending across said flexible member; said loop providing slidable movement of said elbow restraining means relative to said flexible member.
Claim 12
Dependent Claim 72 words
The immobilizer of claim 1 wherein said restraining means includes elbow restraining means pivotally attached to said flexible member whereby said elbow restraining means is alternatively disposed in a first position whereby the elbows of the patient are secured against movement adjacent and alongside the torso of said patient, and pivotally movable to a second position whereby the elbows of the patient are secured against movement alongside the head of said patient.
Claim 13
Dependent Claim 120 words
The immobilizer of claim 11 wherein said elbow restraining means is pivotally attached along a transverse axis to the posterior of said flexible member and is adapted to pivot about said axis to move between said first position and said second position, said elbow restraining means including: pairs of straps attached to said flexible member with mating means on at least one surface of each strap to secure the ends of said straps together when disposed around the elbow of said patient; said straps having slots spaced from the point of attachment to said flexible member; said ends of said straps adapted to be looped through said slots to provide an adjustable restraining means for the elbows of said patient.
