The present invention relates to a bed robot for preventing bedsores that can be used not only by general patients but also by elderly patients, debilitated patients, paralyzed patients, unconscious patients, post-surgical patients, and other critically ill patients who cannot change their positions on their own. More specifically, it relates to a bed robot for preventing bedsores. Tilt the bed left and right, providing optional functionality such as height adjustment, head or leg inclination adjustment, backrest or leg standing angle adjustment, 2-stage folding of the shins and thighs, and left and right tilt adjustment of the bed. It is designed to effectively prevent patients from falling when adjusting, ensuring simplification of structure and safety. In particular, it helps prevent bedsores by periodically providing position changes for critically ill patients who cannot change their position on their own. The goal is to provide a bed robot to prevent bedsores.

In the case of critically ill patients who are unable to change their position on their own, such as elderly patients, weak patients, paralyzed patients, unconscious, or in a post-operative state, the patient's position must be changed at least at intervals of 1 to 2 hours with the help of a caregiver or guardian. Because bedsores occur, you need to change your position at regular intervals and keep the skin around it clean and dry.

For this purpose, medical beds of various configurations are provided.

A representative example is the medical bed proposed in Republic of Korea Patent Publication (B1) 10-0947374 (2010.03.15.), which consists of a pair of opposing fixtures on both walls of the inner center, and each of the bottoms. A bed frame in which legs with moving rollers are installed at the corners, a plurality of red clay bed units are installed, and separation prevention parts are formed on both sides to prevent the red clay bed units from leaving; A support plate installed on the red clay bed unit to support the red clay bed unit; A head portion installed on the support plate, a body portion that extends from the lower side of the head portion to guide the lifting and lowering of the red clay bed unit, and a body portion that extends from the lower side of the body portion, is seated on the upper side of the elastic spring, and is inside the lifting member. An elevating unit consisting of a seating part that applies pressure to the space and installed to maintain a constant height on the floor; A lifting member that is installed on the top of the bed frame and has an elastic spring disposed therein, has an inlet through which oil and pneumatic pressure is injected and discharged, and vertically moves the lifting unit in the up and down directions; a water catcher located in the inner space of the bed frame, wheels installed at each corner of the bottom, and a bottom having a constant slope; It is configured to include an angle adjustment means installed on the bed frame to move the bed frame angularly.

Another example is a medical bed proposed in Republic of Korea Patent Publication (B1) 10-1493467 (2015.02.16.), which consists of a lower frame; an upper frame detachably installed on the lower frame; a patient support frame rotatably installed on the upper frame to support the upper or lower body of the patient, and rotating while moving to one side or the other side of the upper frame; a patient seating unit coupled to the patient support frame so that the patient can lie down; And a medical bed comprising an upper frame lifting part that connects the lower frame and the upper frame and elevates the upper frame in the lower frame, wherein the upper frame lifting part includes: a first driving member installed in the lower frame; a first rotating part rotatably installed on the lower frame to be connected to the first driving member; a second rotating part rotatably installed on the lower frame to interlock with the first rotating part; and a link part that connects the second rotating part and the upper frame, and folds through rotation of the second rotating part to raise and lower the upper frame.

In the case of the above-mentioned conventional medical beds, most of them are configured to implement the function of erecting the patient's upper body, lifting the legs, or adjusting the height of the bed. In the case of caregivers or guardians, the patient can be placed in a variety of positions.
