A combined type nursing bed. A moveable backrest is provided on a fixed bed body, and a wheelchair is disposed at an end of the moveable backrest. The wheelchair includes three rectangular plates, a wheelchair support, and a second driving mechanism. When in use, the three rectangular plates are driven by the second driving mechanism and pivots around rotating shafts to form the wheelchair. The wheelchair can be separated from the bed body. Through separation and combination of the wheelchair and the bed body, a patient can be easily transferred. The transferring process does not require hard labor of the nursing personnel, and the patients do not suffer addition discomfort due to use of the nursing bed.
