Abstract

The invention includes methods and apparatuses for patient transfer from a rollable chair to a bed and back. A rollable chair includes a first frame having a seat; a second frame coupled to the first frame, the second frame having a backrest configured to move relative to the first frame; and a third frame coupled to the first frame, the third frame having a track having a curvilinear length configured to allow the first frame to rotate and to translate relative to the third frame. A bed includes a chair-receiving frame configured to couple to the first frame of the rollable chair. The rollable chair and the bed work in tandem to transfer a patient, for example using coordinated, automated motions.
