A method of transporting a patient from a bed to a hospital table, comprising: positioning a first side of a transfer device adjacent the bed, the transfer device having a base with wheels and support columns, slide frames attached to upper portions of the support columns, carriages slidably supported by the slide frames, and a table assembly carried by said carriages including separable upper and lower tables (34, 36) comprising respective upper and lower belts (40, 48); moving the table assembly from a home position centered over the base to a first extended position at the first side of the transfer device with the upper and lower tables (34, 36) in forcible contact and the upper and lower belts (40, 48) counter-rotating to place the table assembly between the patient and the bed, while keeping the base stationary; separating the upper and lower tables (34, 36) with the table assembly in the first extended position to lift the patient above the bed on the upper table while the lower table remains resting upon the bed; moving the table assembly from the first extended position to the home position while supporting the patient on the upper table, keeping the upper and lower tables (34, 36) separated, with the lower table laterally supporting the transfer device and without any part of the base extending under the bed; moving the transfer device on its wheels from the bed at a first location to the hospital table at a second location while supporting the patient on the upper table and keeping the upper and lower tables (34, 36) separated; positioning the first side of the transfer device adjacent the hospital table; moving the table assembly from the home position to the first extended position at the first side of the transfer device while supporting the patient on the upper table, keeping the upper and lower tables (34, 36) separated, with the lower table laterally supporting the transfer device and without any part of the base extending under the hospital table; lowering the upper table into forcible contact with the lower table while keeping the base stationary; and moving the table assembly from the first extended position to the home position with the upper and lower tables (34, 36) in forcible contact and the upper and lower belts (40, 48) counter-rotating to offload the patient onto the hospital table, while keeping the base stationary. positioning a first side of a transfer device adjacent the bed, the transfer device having a base with wheels and support columns, slide frames attached to upper portions of the support columns, carriages slidably supported by the slide frames, and a table assembly carried by said carriages including separable upper and lower tables (34, 36) comprising respective upper and lower belts (40, 48); moving the table assembly from a home position centered over the base to a first extended position at the first side of the transfer device with the upper and lower tables (34, 36) in forcible contact and the upper and lower belts (40, 48) counter-rotating to place the table assembly between the patient and the bed, while keeping the base stationary; separating the upper and lower tables (34, 36) with the table assembly in the first extended position to lift the patient above the bed on the upper table while the lower table remains resting upon the bed; moving the table assembly from the first extended position to the home position while supporting the patient on the upper table, keeping the upper and lower tables (34, 36) separated, with the lower table laterally supporting the transfer device and without any part of the base extending under the bed; moving the transfer device on its wheels from the bed at a first location to the hospital table at a second location while supporting the patient on the upper table and keeping the upper and lower tables (34, 36) separated; positioning the first side of the transfer device adjacent the hospital table; moving the table assembly from the home position to the first extended position at the first side of the transfer device while supporting the patient on the upper table, keeping the upper and lower tables (34, 36) separated, with the lower table laterally supporting the transfer device and without any part of the base extending under the hospital table; lowering the upper table into forcible contact with the lower table while keeping the base stationary; and moving the table assembly from the first extended position to the home position with the upper and lower tables (34, 36) in forcible contact and the upper and lower belts (40, 48) counter-rotating to offload the patient onto the hospital table, while keeping the base stationary.
