The invention discloses a manual back-lifting and leg-bending nursing bed for a patient and belongs to the field of nursing beds. The nursing bed comprises a bed body frame, a bed board, a back-lifting device and a leg-bending device. The bed board is of a curtain-shaped structure allowing longitudinal bending. The back-lifting device comprises back-lifting supports, back-lifting rotating shafts, back-lifting traction ropes and a manual back-lifting traction locking mechanism. The back-lifting supports are hinged to the bed body frame through the back-lifting rotating shafts, one end of each back-lifting traction rope is connected with a lever arm on the corresponding back-lifting support, and the other end of each back-lifting traction rope is connected with the manual back-lifting traction locking mechanism. The leg-bending device comprises leg-bending sliding supports, leg-bending sliding blocks, leg-bending guide rails, guide rail supports, leg-bending traction ropes and a manual leg-bending traction locking mechanism. The guide rail supports are installed on the bed body frame, the leg-bending guide rails are fixed to the guide rail supports, and the leg-bending sliding supports are matched with the leg-bending guide rails through the leg-bending sliding blocks. Back-lifting and leg-bending noise is small, the motion is smooth, operation is easy, and the nursing bed makes the patient feel more comfortable and is especially suitable for a paralytic without the self-care ability.
