The invention provides an independent column bag-type intelligent flexible automatic turnover nursing bed, belonging to the technical fields of medical care and automatic control. The independent column bag-type intelligent flexible automatic turnover nursing bed is composed of closed bag-type water storage equipment, a motor-driven pump, a water bag group, a main controller and a bed support. The automatic turnover nursing bed has the beneficial effects as follows: by means of full utilization of the thermal conductivity and incompressibility of water, accurate control of body temperature and prone position of human body can be realized by controlling water temperature as well as the pressure and flow of water bags in various units, and meanwhile the nursing bed in the operating process can keep quiet without air current noise like that of an air bag device; and as a proportional servo valve is employed for controlling water flow, water filling and discharging time of each water bag can be adjusted artificially so as to achieve the purpose of humanized control of tolerance level of patients during different periods. The automatic turnover nursing bed can regulate body temperature, flexibly change the prone position of a patient lying in bed for long term according to the acceptance of the patient, promote blood circulation, monitor the state of the patient in real time by controlling a computer and various sensors, reduce nursing workload and false accept rate of nursing personnel maximally and improve comfort level of the patient. The independent column bag-type intelligent flexible automatic turnover nursing bed has the advantages of compact structure, fewer parts, lighter weight compared with the similar device, and small packing size, and is easy to replace damaged parts, and is applicable to the environment in shortage of medical personnel for disaster relief, battlefield nursing and the like.
