  • Padded x-ray compatible spine board
    Patent number: 6915805
    Abstract: A molded plastic spine board having specialized padding strategically located in the board and stiffing members. The specialized padding reduces patient discomfort and aids perfusion in the regions that are in contact with the board while the patient is immobilized on the board thereby helping to prevent tissue ischemia and pressure ulcer formation. The stiffening members strengthen the board eliminating deflection of the board thereby keeping the patient immobilized while eliminating artifacts (shadows and interference) in x-rays thereby ensuring good x-ray examination.
