Abstract
Abstract The apparatus disclosed includes a patient-supporting chair that is mounted on a shaft for rotation with the shaft as the shaft rotates around its longitudinal axis. The chair can be rotated around a second axis that is perpendicular to the longitudinal axis of the shaft. This allows the chair to be oriented to rotate with the patient facing toward or away from the direction of rotation to place the patient in positions such as head-up, headdown, brow-up or brow-down. Also, the chair can be oriented with the patient facing generally perpendicular to the direction of rotation of the chair for movement of the patient to positions such as the right and left decubitas positions.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
149 words
Patient-supporting apparatus for moving patients to a variety of positions comprising a base, a chair for supporting a patient including a seat and a back, and means on the base for supporting and rotating the chair, said means including power means having a cantilevered output shaft rotatable by the power means around its longitudinal axis and means mounting the chair on the cantilevered output shaft for rotation with the shaft around its longitudinal axis and for rotation around an axis generally perpendicular to the longitudinal axis of the output shaft whereby the chair can be positioned to orient the patient to face toward or away from the direction the chair is rotated by the output shaft or to face generally in the direction of the axis of rotation of the output shaft to permit the patient to be moved to a variety of positions while supported by the chair.
Claim 2
Dependent Claim
149 words
Patient-supporting apparatus for moving patients to a variety of positions comprising a base, a chair for supporting a patient including a seat and a back, and means on the base for supporting and rotating the chair, said means including power means having a cantilevered output shaft rotatable by the power means around its longitudinal axis and means mounting the chair on the cantilevered output shaft for rotation with the shaft around its longitudinal axis and for rotation around an axis generally perpendicular to the longitudinal axis of the output shaft whereby the chair can be positioned to orient the patient to face toward or away from the direction the chair is rotated by the output shaft or to face generally in the direction of the axis of rotation of the output shaft to permit the patient to be moved to a variety of positions while supported by the chair.
Claim 3
Dependent Claim
58 words
The apparatus of claim 1 further provided with means for holding the chair against rotation around the axis perpendicular to the longitudinal axis of the shaft when the chair is in the desired position relative to this axis, said means being releasable to permit the chair to be moved to another position relative to said axis when desired.
Claim 4
Dependent Claim
127 words
The apparatus of claim 1 further provided with adjustable cassette holder means including a cassette holder, a first member pivotally attached to the cassette holder, a second member pivotally and movably attached to the first member and to the back of the chair whereby the cassette holder can pivot relative to the first member, the first member can pivot and move axially relative to the second member, and the second member can pivot and move axially relative to the chair all as required to place the cassette holder in the desired position relative to a patient''s head when the patient is sitting in the chair and means for holding each member independently from such pivotal and sliding movement when the cassette holder is in the desired position.
Claim 5
Dependent Claim
138 words
A patient-supporting chair for moving patients to a variety of positions as required for example for a pneumoencephalogram comprising a chair having a seat and a back, means supporting the chair and for rotating the chair in a vertical plane around a horizontal axis, a base, and a column on the base for supporting the chair-supporting and rotating means, said supporting and rotating means including power means having a cantilevered horizontal output shaft and means mounting the seat of the chair on the cantilevered output shaft adjacent its unsupported end for rotation around a second axis perpendicular to the horizontal longitudinal axis of the output shaft to permit the patient to be placed in brow-up, brow-down, and head-hanging positions and by rotating the chair around said second axis to be placed in the left and right decubitas positions.
Claim 6
Dependent Claim
138 words
A patient-supporting chair for moving patients to a variety of positions as required for example for a pneumoencephalogram comprising a chair having a seat and a back, means supporting the chair and for rotating the chair in a vertical plane around a horizontal axis, a base, and a column on the base for supporting the chair-supporting and rotating means, said supporting and rotating means including power means having a cantilevered horizontal output shaft and means mounting the seat of the chair on the cantilevered output shaft adjacent its unsupported end for rotation around a second axis perpendicular to the horizontal longitudinal axis of the output shaft to permit the patient to be placed in brow-up, brow-down, and head-hanging positions and by rotating the chair around said second axis to be placed in the left and right decubitas positions.
Claim 7
Dependent Claim
23 words
The chair of claim 4 in which the column is extendable and retractable to permit the height of the chair to be adjusted.
