Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of old people nursing, specifically to a turning-over device for old people nursing. BACKGROUND

[0002] For some paralytic patients or postoperative patients, most of the time is lying on the nursing bed during the recovery period. Long time lying on the nursing bed can easily cause poor blood circulation and even bedsores. In order to promote blood circulation and prevent bedsores, the patient needs to continuously perform side-lying activities to the left or right with the assistance of others, and after side-lying, a sponge triangular pillow is used to support the back part, so that the body maintains a certain lateral decubitus inclination.

[0003] According to the search of the publication No. (CN113662773A), a turning-over device for nursing bed for old people is disclosed, which comprises a support frame, a backrest plate, an auxiliary plate, a main bed plate and a turning-over plate. The backrest plate, the auxiliary plate, the main bed plate and the turning-over plate are all connected to the support frame. A screw rod is rotatably connected to the support frame. A screw sleeve is threadedly connected to the screw rod. The screw sleeve is rotatably connected to the backrest plate through a lifting mechanism. A rotating rod and a driven rod are rotatably connected to the support frame. The rotating rod is rotatably connected to the driven rod through a first transmission mechanism. Gears are fixedly connected to the rotating rod and the driven rod. A rack is slidably connected to the support frame.

[0004] In the implementation of this technical solution, at least the following defects exist: Although the invention can perform turning-over operation on the patient, the turning-over plate must have a gap with the bed frame due to the need for upward turning. However, the gap between the turning-over plate and the bed frame can cause the patient's limbs (such as hands and feet) to be clamped into the gap, thereby causing the old person to be injured. Moreover, the existence of the gap can also cause the mobile phone and other items placed on the bedside to fall to the bed below and cause damage, which needs to be improved. Therefore, we propose a turning-over device for old people nursing. UTILITY MODEL CONTENTS

The lead screw can drive the jacking plate to move leftward through the lead screw sleeve, the jacking plate is in contact with the inclined surface of the wedge block, the jacking plate pushes the turning-over plate to rotate upward, thereby realizing the turning-over operation of the old people. When the turning-over is completed, the fixed rod can move upward driven by the traction rope, the rubber plate can be inserted between the bed frame and the turning-over plate driven by the fixed rod, thereby sealing the gap between the turning-over plate and the bed frame. The gap between the turning-over plate and the bed frame can prevent the patient's limbs (such as hands and feet) from being clamped into the gap, thereby preventing the old people from being injured. Moreover, the situation that the mobile phone and other articles fall from the gap and are damaged can be avoided.

[0009] Optionally, the lower end of the jacking plate is fixedly installed with a lead screw sleeve, and the lead screw is threadedly connected with the lead screw sleeve.
