Description

Aid device for turning patient posture and bed for turning patient posture The present invention relates to a patient position changing aid and a patient position changing bed. More specifically, the invention relates to a patient position changing aid and a patient position changing bed that can facilitate changing the position to suit the patient in order to prevent bedsores. Patients with physical paralysis or those with limited mobility often lie in bed in the same position for a long time. When lying in bed in the same position for an extended period, excessive pressure is applied to the back or buttocks, which can lead to the development of pressure sores in the affected areas. To prevent the occurrence of pressure ulcers, the patient's position must be changed at regular intervals; however, since the location of pressure ulcers varies from patient to patient, it is important to change the position to suit the individual patient. Nurses or caregivers caring for patients must frequently change the patient's position to suit them, and to prevent bedsores, an assistive device is needed to facilitate such position changes. FIG. 1 is a simplified perspective view illustrating a patient position changing bed equipped with a patient position changing assist device according to one embodiment of the present invention. FIG. 2 is a diagram illustrating the coupling relationship between a longitudinal frame and an electric pulley of a patient posture changing assistive device according to one embodiment of the present invention. FIG. 3 is a drawing illustrating a method for assembling a patient posture changing assistive device according to an embodiment of the present invention. FIGS. 4 to 6 are drawings for explaining a method of changing a patient's posture using a patient posture changing assistive device according to an embodiment of the present invention.
